Exemptions From Average Fuel Economy Standards; Passenger 
Automobile Average Fuel Economy Standards

AGENCY: National Highway Traffic Safety Administration (NHTSA), 
Department of Transportation (DOT).

ACTION: Proposed rule; proposed decision to grant exemption.

-----------------------------------------------------------------------

SUMMARY: This proposed decision responds to petitions filed by several 
low volume manufacturers requesting exemption from the generally 
applicable corporate average fuel economy (CAFE) standards for several 
model years (MYs). The low volume manufacturers and MYs are as follows: 
Aston Martin Lagonda Limited for MYs 2008-2023, Ferrari N.V. for MYs 
2016-2018 and 2020, Koenigsegg Automotive AB for MYs 2015 and 2018-
2023, McLaren Automotive for MYs 2012-2023, Mobility Ventures LLC for 
MYs 2014-2016, Pagani Automobili S.p.A for MYs 2014 and 2016-2023, and 
Spyker Automobielen B.V. for MYs 2008-2010. NHTSA proposes to exempt 
these manufacturers from the generally applicable CAFE standards for 
the model years listed and establish alternative standards for each 
individual manufacturer at the levels outlined below.

1. Introduction

    The Energy Policy and Conservation Act (EPCA) of 1975, as amended 
by the Energy Independence and Security Act (EISA) of 2007,\1\ directs 
the Secretary of Transportation, and the National Highway Traffic 
Safety Administration (NHTSA) by delegation,\2\ to prescribe corporate 
average fuel economy (CAFE) standards for automobiles manufactured in 
each model year (MY). EPCA/EISA requires NHTSA to establish CAFE 
standards for passenger cars and light trucks at the ``maximum feasible 
average fuel economy level'' that it decides manufacturers can achieve 
in a MY,\3\ based on the agency's consideration of four factors: 
technological feasibility, economic practicability, the effect of other 
standards of the Government on fuel economy, and the need of the United 
States to conserve energy.\4\
---------------------------------------------------------------------------

    \1\ 49 U.S.C. 32902.
    \2\ 49 CFR 1.95.
    \3\ 49 U.S.C. 32902(a).
    \4\ 49 U.S.C. 32902(f).
---------------------------------------------------------------------------

    Congress provided in EPCA/EISA statutory authority for NHTSA to 
exempt a low volume manufacturer of passenger automobiles from the 
industry-wide passenger car standard if NHTSA concludes that the 
industry-wide passenger car standard is more stringent than the maximum 
feasible average fuel economy level that the manufacturer can achieve, 
and NHTSA establishes an alternative standard for that manufacturer's 
fleet of passenger cars at the maximum feasible average fuel economy 
level that the manufacturer can achieve.\5\ Under EPCA/EISA, a low 
volume manufacturer is one that manufactured (whether in the United 
States or not) fewer than 10,000 passenger automobiles in the MY two 
years before the MY for which the exemption is sought, and that will 
manufacture fewer than 10,000 passenger automobiles in the affected MY. 
NHTSA may set alternative fuel economy standards in three ways: (1) a 
separate standard for each exempted manufacturer; (2) a separate 
standard applicable to each class of exempted automobiles (classes 
based on design, size, price or other factors); or (3) a single 
standard for all exempted manufacturers.\6\ NHTSA has historically set 
individual standards for each exempted manufacturer.

    49 CFR part 525 contains NHTSA's regulations implementing the 
statutory requirements in 49 U.S.C. 32902. This part provides content 
and format requirements for low volume manufacturer petitions for 
exemption, and specifies that those petitions must be submitted to 
NHTSA not later than 24 months before the beginning of the affected 
model year, unless good cause for later submission is shown.\7\ That 
part also outlines the NHTSA process for publishing proposed and final 
decisions on petitions in the Federal Register and for accepting public 
input on proposed decisions.\8\ A manufacturer's final alternative 
standard is codified at 49 CFR part 531.
---------------------------------------------------------------------------

    \7\ 49 CFR 525.6(b). See also 54 FR 40689 (Oct. 3, 1989). NHTSA 
has identified two broad categories of situations that would 
establish good cause for failure to submit a timely petition: 
situations in which necessary supporting data for the petition were 
unavailable until after the due date had passed (for example, a 
recently incorporated manufacturer might not have adequate time to 
file an exemption petition 24 months prior to the model year), and 
second, situations in which a legitimately unexpected noncompliance 
occurs (for example, if a company providing a low volume 
manufacturer with its engines goes out of business, and the 
manufacturer is forced to make an unanticipated engine switch, 
resulting in lower than expected fuel economy). That said, each 
determination that good cause was or was not shown for the late 
filing is made on an individual basis. Manufacturers should reach 
out to NHTSA as expeditiously as possible if they expect they cannot 
submit a petition in a timely manner.
    \8\ 49 CFR 525.8.
---------------------------------------------------------------------------

    This proposed decision responds to petitions filed by Aston Martin 
Lagonda Limited (AML) for MYs 2008-2023, Ferrari N.V. (Ferrari) for MYs 
2016-2018 and 2020, Koenigsegg Automotive AB (Koenigsegg) for MYs 2015 
and 2018-2023, McLaren Automotive (McLaren) for MYs 2012-2023, Mobility 
Ventures LLC (Mobility Ventures) for MYs 2014-2016, Pagani Automobili 
S.p.A (Pagani) for MYs 2014 and 2016-2023,\9\ and Spyker Automobielen 
B.V. (Spyker) for MYs 2008-2010. NHTSA proposes to conclude that all 
seven manufacturers were, and are, eligible for an alternative standard 
for the listed model years, that the industry-wide passenger car CAFE 
standard for those model years is more stringent than the maximum 
feasible average fuel economy level that those manufacturers could, and 
can, achieve, and that alternative standards should be set at the 
levels discussed below.
---------------------------------------------------------------------------

    \9\ Pagani petitioned for alternative standards for MYs 2012-
2021 but did not produce any vehicles for sale in the U.S. market in 
MYs 2012, 2013, and 2015.
---------------------------------------------------------------------------

2. Evaluation of Maximum Feasible Fuel Economy Levels

    NHTSA has not granted petitions for alternative standards for 
several low volume manufacturers for several model years, both past and 
imminent future. If NHTSA does not set an alternative standard for a 
petitioning manufacturer, that manufacturer would be subject to the 
industry-wide passenger car standard(s) for the model year(s) in 
question, and would therefore be liable for civil penalties if it was 
unable to comply with those standards. At this

[[Page 39441]]

point, any NHTSA action prescribing alternative standards for past 
model years is retroactive.\10\
---------------------------------------------------------------------------

    \10\ See Bowen v. Georgetown University Hospital, 488 U.S. 204, 
208 (1988). The Supreme Court in Bowen v. Georgetown University 
Hospital laid the foundation for modern retroactivity jurisprudence 
by pronouncing that ``[r]etroactivity is not favored in the law.'' 
Justice Kennedy, writing for the majority, and Justice Scalia, 
writing in his concurrence, established the competing principles 
that a statute can explicitly authorize retroactive rulemaking where 
Congress conveys the power to do so in express terms, and a statute 
can implicitly authorize retroactive rulemaking, as in situations 
where an agency misses a statutory deadline to promulgate a rule, or 
similarly, where an agency's inaction would have eliminated a 
Congressionally-prescribed exemption.
---------------------------------------------------------------------------

    However, NHTSA has previously granted low volume exemption 
petitions retroactively when the agency did not publish proposed and 
final determinations on those exemption petitions prior to the 
beginning of a model year.\11\ In these previous notices, NHTSA 
recognized that the agency's ability to adopt retroactive rules is very 
limited but noted that there were compelling reasons to distinguish low 
volume CAFE exemptions. NHTSA reasoned that if the agency could not 
issue exemptions from the industry-wide CAFE standards for low volume 
manufacturers after the commencement of a model year, the agency would, 
by inaction, have ``totally eliminated the congressionally prescribed'' 
low volume manufacturer exemption for the manufacturers and years in 
question.\12\ NHTSA also stated that the agency's failure to act upon 
timely applications for low volume exemptions from the industry-wide 
CAFE standard is analogous to a situation where an agency misses a 
statutory deadline and then must issue a rule retroactively, 
particularly since the manufacturers were in no way responsible for the 
agency's inaction. To avoid unfairly penalizing the low volume 
manufacturers for agency inaction that was beyond their control, NHTSA 
reasoned that EPCA must be construed to implicitly authorize the grant 
of retroactive low volume exemptions.
---------------------------------------------------------------------------

    \11\ See, e.g., 43 FR 33268 (July 31, 1978); 49 FR 11548 (March 
1, 1979); 46 FR 29944 (June 4, 1981); 54 FR 40689 (October 3, 1989); 
55 FR 12485 (April 4, 1990).
    \12\ Supra note 10.
---------------------------------------------------------------------------

    Since those decisions, the D.C. Circuit in General Motors Corp. v. 
National Highway Traffic Safety Administration stated, in dicta, that 
EPCA provided support for NHTSA to set retroactive alternative fuel 
economy standards for low volume manufacturers.\13\ In considering the 
congressional authorization for NHTSA's ability to retroactively amend 
a CAFE standard for LVMs, but not full-line manufacturers,\14\ the 
court agreed with the agency's explanation that ``granting retroactive 
exemptions from the generally applicable standard for low-volume 
manufacturers does not have the same potential for disrupting the 
statutory scheme as retroactively amending the standard as it applies 
to the rest of the industry.'' \15\ The court also noted that Congress 
had, in EPCA and accompanying legislative history, ``[sent] out strong 
signals that [low volume] manufacturers are to be treated differently 
from the rest of the industry.'' \16\ Because LVMs only account for a 
fraction of the total annual production of passenger automobiles, the 
LVMs have limited engineering staff and limited market, and each 
exemption applies to only one manufacturer, ``NHTSA is well within its 
authority to proceed on a case-by-case basis to exempt small 
manufacturers from the industry-wide CAFE standards, and establish an 
individualized CAFE for each exempted manufacturer.'' \17\
---------------------------------------------------------------------------

    \13\ General Motors Corp. v. National Highway Traffic Safety 
Admin., 898 F.2d 165, at 171 (1990).
    \14\ Id. at 176. The court agreed with NHTSA that it was 
reasonable to deny a 1987 petition and subsequent petition for 
reconsideration from General Motors (GM) to retroactively amend the 
1984 and 1985 industry-wide CAFE standard. NHTSA had denied GM's 
petitions on the basis that retroactive amendment would be 
inconsistent with the EPCA statutory scheme. Subsequent to NHTSA's 
original petition denials but before General Motors Corp., the 
Supreme Court addressed retroactive rulemaking in Bowen, and NHTSA 
added to its original argument that ``beyond the independent 
validity of its petition denials, any retroactive amendment of the 
[industry-wide] CAFE standard is barred by the Bowen decision.''
    \15\ Id. (citing 53 FR 15246 (April 28, 1988)).
    \16\ Id. (citing 44 FR 3710 (Jan. 18, 1979), 53 FR 15241 (April 
28, 1988)).
    \17\ Id. at 177. Chief Judge Wald went on to state that, 
similarly, ``[e]ven assuming a general policy of granting 
retroactive exemptions after the model year had begun for a segment 
of the industry accounting for significantly less than one percent 
of the product, NHTSA could reasonably have a different policy for 
the other 99 percent.''
---------------------------------------------------------------------------

    If NHTSA could not set standards for these past model years, the 
low volume manufacturers would be liable for civil penalties for 
noncompliance, and would have to either pay the penalty or buy 
unexpired fuel economy credits \18\ from other manufacturers to make up 
the deficit between their fleet fuel economy and the industry-wide 
passenger car standard. This would be a reversal of several decades of 
NHTSA policy to grant appropriately submitted petitions for alternative 
standards,\19\ \20\ and with functionally no notice. A petitioning 
manufacturer would have had no reason to believe that NHTSA would not 
act in a timely fashion on its request based on prior agency practice; 
that is, it could not have known that it needed suddenly to drastically 
improve its fleet fuel economy, or alternatively, needed suddenly to 
pay civil penalties for failure to meet the industry-wide standard. 
Accordingly, NHTSA continues to believe that EPCA/EISA permits the 
agency to set alternative standards for past MYs. In support of this 
position, NHTSA has also deferred sending the required enforcement 
notification to the manufacturers considered in this notice for falling 
below the conventional passenger car standards until any outstanding 
petitions for the given model year have been resolved.\21\
---------------------------------------------------------------------------

    \18\ NHTSA has deleted all MY 2012 and earlier credits which 
have reached their expiry date in accordance with 49 CFR 
536.5(c)(2).
    \19\ See supra, note 11.
    \20\ Note, this is a different inquiry than whether the LVM's 
maximum feasible fuel economy level is the level that it petitioned 
for, or some other level. NHTSA can grant the petition for review 
then set a different standard than the manufacturer requested.
    \21\ If a manufacturer's vehicles in a particular compliance 
category have below standard fuel economy, NHTSA will provide 
written notification to the manufacturer that it has failed to meet 
a particular fleet target standard. See 49 CFR 536.5(d)(2).
---------------------------------------------------------------------------

a. Determining ``Maximum Feasible'' Under EPCA/EISA

    NHTSA has determined that EPCA/EISA permits the agency to 
retroactively set fuel economy standards for low volume manufacturers. 
However, determining how to prescribe an alternative fuel economy 
standard at the maximum feasible level for past model years is a 
separate question.
    NHTSA relies heavily on the information that a low volume 
manufacturer submits in its petition in determining what maximum 
feasible fuel economy level is achievable for that manufacturer. 
Evaluating that information well in advance of a model year for which 
the petition is submitted invariably aids NHTSA in setting a LVM's 
alternative standard at its maximum feasible level; attempting to 
determine now how the agency would have evaluated the information 
included in the petition seems like an imprecise, if not also futile, 
exercise because the agency already knows what fuel-economy-improving 
technologies the LVM applied, and importantly (and irrevocably), the 
vehicles have already been sold. Regardless of what average fuel 
economy level the LVMs told the agency they could achieve in each model 
year, the LVMs achieved the levels they achieved, and that information 
is now before the agency along with the information originally 
submitted by the LVMs. Thus, the

[[Page 39442]]

agency will consider all currently available information in proposing 
maximum feasible levels for each LVM.
    Accordingly, NHTSA believes the question that the agency must 
answer now for past model years is, given all information currently 
before the agency, what fuel economy levels were the maximum feasible 
levels that each LVM could have achieved in each model year?
    For imminently future model years, the agency must answer a 
slightly different set of questions; that is, is the alternative 
standard that the manufacturer petitioned for maximum feasible, and if 
not, what, if any, technologically feasible and economically 
practicable changes would the manufacturer be able to make in the time 
frame before model year production would need to commence? A vehicle 
manufacturer's model year typically begins before the calendar year 
(e.g., model year 2020 vehicles are manufactured beginning in calendar 
year 2019). Vehicle designs (including drivetrains, which are where 
many fuel economy improvements are made) are often fixed years in 
advance, which makes adjusting fleet fuel economy difficult without 
sufficient lead time. For most manufacturers, production plans are 
solidified at least 18 months in advance of a model year, and there is 
limited ability to deviate.
    While EPCA/EISA does not prescribe a statutory deadline by which 
NHTSA must act on low volume exemption applications, in establishing 
the regulations implementing EPCA's low volume manufacturer exemption 
provisions, the agency required low volume manufacturers to submit 
petitions for exemption ``not later than 24 months before the beginning 
of the affected model year'' to ``facilitate the low volume 
manufacturers' planning to comply with the alternative standards, and 
to ensure that the agency's analysis of those manufacturers' maximum 
feasible average fuel economy would not be simply a `rubber stamping' 
of the individual manufacturer's planned fuel economy, caused by 
insufficient leadtime for the manufacturer to make changes.'' \22\ As a 
practical matter, the greater the difference between what NHTSA 
believes is the maximum feasible standard and what the manufacturer 
petitioned for, the more time the manufacturer likely needs to adjust 
product designs and plans to meet that standard.
---------------------------------------------------------------------------

    \22\ See 41 FR 53827, 53828 (Dec. 9, 1976); 54 FR 40690 (October 
3, 1989). See also 49 U.S.C. 32902(a), 81 FR 95491 (Dec. 28, 2016). 
EPCA/EISA requires that when NHTSA amends a generally applicable 
fuel economy standard to make it more stringent, that new standard 
must be promulgated ``[a]t least 18 months before the beginning of 
each model year.'' This is because Congress recognized the 
importance of notice to vehicle manufacturers to allow them the lead 
time necessary to adjust their product plans, designs, and 
compliance plans to address changes in fuel economy standards.
---------------------------------------------------------------------------

    With these considerations and questions in mind, NHTSA summarizes 
the methodology used to assess the petitioners' maximum feasible 
average fuel economy levels, and the information submitted by 
petitioners to assist in that assessment, below.

b. Methodology Used To Assess Maximum Feasible Average Fuel Economy 
Level for Petitioners

    As an initial matter, all manufacturers considered in this proposed 
decision met the threshold statutory requirements for eligibility; that 
is, all manufacturers manufactured or will manufacture fewer than 
10,000 vehicles in the applicable model years. Some petitions for some 
model years were submitted late, although the late filings were 
accompanied with good cause claims, per 49 CFR part 525.\23\ Regardless 
of the sufficiency of those good cause claims, NHTSA believes that due 
to the significant lateness of the agency's response to these specific 
exemption requests, it would be inequitable at this point to deny the 
late petitions on grounds of untimeliness. Moving forward, NHTSA 
expects manufacturers to remain cognizant of the requirement that each 
submission must be submitted not later than 24 months before the 
beginning of the affected model year, unless good cause for later 
submission is shown. While each good cause claim is evaluated on an 
individual basis, NHTSA encourages manufacturers to contact the agency 
as early as possible if they begin to expect a petition for exemption 
may be delayed. Once a manufacturer is aware of its obligations 
regarding petitions for exemption from CAFE standards, arguing that a 
company is ``busy simply trying to survive as a small manufacturer'' is 
not enough to show good cause for late submission of an exemption 
petition.\24\
---------------------------------------------------------------------------

    \23\ 49 CFR 525.6 (``Each petition filed under this part must . 
. . Be submitted not later than 24 months before the beginning of 
the affected model year, unless good cause for later submission is 
shown.'').
    \24\ 56 FR 3517 (Jan. 30, 1991).
---------------------------------------------------------------------------

    When proposing maximum feasible average fuel economy levels, NHTSA 
must consider four factors: technological feasibility, economic 
practicability, the effect of other motor vehicle standards of the 
Government on fuel economy, and the need of the United States to 
conserve energy. The agency's consideration of these factors in 
relation to low volume manufacturers differs from how the agency 
considers these factors for full-line manufacturers; the consideration 
of these factors as applied to past model years as compared to future 
model years necessarily differs as well.
    ``Technological feasibility'' refers to whether a particular method 
of improving fuel economy can be available for commercial application 
in the model year for which a standard is being established. 
Historically, for both low volume and full-line manufacturers, NHTSA 
has looked at manufacturers' use of fuel-economy improving technologies 
for weight reduction and aerodynamic improvements, engine improvements, 
and transmission improvements, among other technologies. Moving 
forward, NHTSA is also considering another category of technologies, 
off-cycle and air conditioning (A/C) efficiency improvement 
technologies. These technologies provide fuel economy improvements in 
real-world operation, but that improvement cannot be adequately 
captured by the 2-cycle test procedures used to demonstrate compliance 
with fuel economy standards. These off-cycle and A/C efficiency 
improvement technologies fall within the scope of technologies that 
manufacturers must discuss in their petitions to the agency,\25\ and 
the manufacturer should include any anticipated benefit from those off-
cycle and A/C efficiency improvement technologies in the projected fuel 
economy value for each vehicle configuration as required by 49 CFR 
525.7(f).
---------------------------------------------------------------------------

    \25\ 49 CFR 525.7(h)(1).
---------------------------------------------------------------------------

    Next, NHTSA considers ``economic practicability'' for petitions 
filed under 49 CFR part 525 as meaning the financial capability of the 
manufacturer to improve its average fuel economy by making 
technologically feasible changes to its passenger automobiles for the 
model years under consideration.\26\ Technological feasibility and 
economic practicability are often conflated; whether a fuel-economy-
improving technology does or will exist (technological feasibility) is 
a different question from what economic consequences could ensue if 
NHTSA effectively requires a low volume manufacturer utilize that 
technology, and the economic consequences of the absence of consumer 
demand for low volume vehicles utilizing that technology (economic 
practicability).
---------------------------------------------------------------------------

    \26\ See, e.g., 42 FR 33533 (June 30, 1977).

---------------------------------------------------------------------------

[[Page 39443]]

    As part of economic practicability, NHTSA has historically 
considered only those technology improvements that would be compatible 
with the basic design concepts of the low volume manufacturers' 
vehicles. For example, for vehicles exclusively designed to be used for 
transporting the wheelchair bound or other mobility-impaired 
individuals, NHTSA did not consider design changes that would impair 
the ability of the vehicle to perform that function; \27\ for a five-
passenger luxury car, NHTSA did not consider ``design changes that 
would make the cars unsuitable for five adult passengers with luggage 
or would remove items traditionally offered on luxury cars, such as air 
conditioning, automatic transmission, power steering, and power 
windows;'' \28\ and for ``exotic high performance cars, design changes 
that would remove items traditionally offered on these cars, such as 
reducing the displacement of their engines, were not considered.'' \29\ 
This is because ``[s]uch changes to the basic design could be 
economically impracticable since they might well significantly reduce 
the demand for these automobiles, thereby reducing sales and causing 
significant economic injury to the low volume manufacturer.'' \30\ 
Market demand has been part of economic practicability considerations 
for decades, both in the industry-wide and low-volume CAFE 
programs.\31\

Citizen v. NHTSA, 848 F.2d 256 (Congress established broad 
guidelines in the fuel economy statute; agency's decision to set 
lower standards was a reasonable accommodation of conflicting 
policies). See also 58 FR 41229 (Aug. 3, 1993) (``Consumers need not 
purchase what they do not want.'').
---------------------------------------------------------------------------

    Between different types of low volume manufacturers, different 
technologies may or may not be available for commercial application for 
certain types of vehicles because of supply chain considerations and 
economies of scale. NHTSA has previously recognized that low volume 
manufacturers lag in having the latest developments in fuel-economy-
improving technology because suppliers generally provide components to 
small manufacturers only after supplying large manufacturers.\32\ 
Similarly, full-line manufacturers that provide engines and 
transmissions to small volume manufacturers may only do so after 
developing those parts for use in their own vehicles. In fact, as 
discussed below, some manufacturers requesting alternative standards 
rely on full-line manufacturers to provide customized engines for their 
vehicles.
---------------------------------------------------------------------------

    \32\ See, e.g., 61 FR 39429 (July 29, 1996); 61 FR 67518 
(December 23, 1996); 63 FR 5774 (February 4, 1998); 64 FR 73476 
(December 30, 1999); 71 FR 49407 (August 23, 2006); 73 FR 34242 
(June 17, 2008).
---------------------------------------------------------------------------

    That said, some of the vehicles covered by this proposed decision 
employ some of the most advanced fuel-economy-improving technologies 
available in the market today, but to improve other vehicle attributes. 
For example, as mentioned below, NHTSA generally considers 
turbochargers to be an effective technology to improve vehicle fuel 
economy; however, a high-performance sports car manufacturer may use 
turbochargers to increase vehicle power. Under NHTSA's historical 
interpretation of economic practicability for low volume manufacturers, 
a low volume manufacturer would justify in its petition to the agency 
whether it could direct some performance improvement towards fuel 
economy, and if not, why not. This requirement is echoed in NHTSA's 
regulations governing petition information: petitioners must include a 
discussion of the technological means selected by the petitioner for 
improving the average fuel economy of its vehicles and a discussion of 
the alternative and additional means considered but not selected that 
would have enabled its vehicles to achieve a higher average fuel 
economy than it did.\33\
---------------------------------------------------------------------------

    \33\ 49 CFR 525.7(h).
---------------------------------------------------------------------------

    Economic practicability can also encompass considerations like the 
manufacturer's ability to refresh and redesign their vehicles based on 
the availability of technology, as discussed above, or other factors. 
Manufacturers use diverse strategies with respect to when, and how 
often, they update vehicle designs. While most vehicles have been 
redesigned sometime in the last five years, many vehicles have not.\34\ 
For low volume manufacturers, that time frame can potentially be even 
longer given the nature of their products. Vehicles with lower annual 
sales volumes tend to be redesigned less frequently, giving 
manufacturers more time to amortize the investment needed to bring the 
product to market. To the extent that a manufacturer includes these 
economic practicability concerns in their petition for exemption, NHTSA 
considers this alongside the evaluation of potential technological 
improvements.
---------------------------------------------------------------------------

    \34\ See, e.g., 83 FR 43014 (Aug. 24, 2018) (Table II-3, Summary 
of Sales Weighted Average Time between Engineering Redesigns, by 
Manufacturer, by Vehicle Technology Class).
---------------------------------------------------------------------------

    NHTSA also considers a low volume manufacturer's ability to improve 
fuel economy by changing the mix of vehicle models it sells. Where a 
low volume manufacturer only produces one vehicle model, there is no 
change that they can make to their fleet sales mix to achieve a higher 
fleet average fuel economy level. Where a manufacturer only produces a 
handful of vehicle models, there may be slightly more opportunity; \35\ 
however, a manufacturer's ability to change its fleet mix may also be a 
component of its sales strategy, and a limitation of producing such a 
niche product. Where ``producing additional models or making some of 
the configurations significantly more fuel efficient is not possible 
since both corporate financial limitations and the unique market sector 
served by [the low volume manufacturer] preclude significant changes to 
the basic concept of'' the low volume manufacturers' vehicles, NHTSA 
has not previously required those types of changes.\36\
---------------------------------------------------------------------------

    \35\ Because CAFE standards apply to a manufacturer's fleet 
rather than to individual vehicles, it is possible for a 
manufacturer's fuel economy performance to fluctuate yearly based 
not only on changes in the fuel economy of each of its models, but 
also based on changes in the production volumes of those models. 
There may be situations in which a manufacturer makes no changes to 
the fuel economy of any of its models from one year to the next, but 
its fleet average decreases because of changes in the production 
volumes of the individual vehicle models it produces. This may occur 
even when a manufacturer makes improvements in the fuel economy of 
one or more individual vehicle models from one year to the next.
    \36\ See 58 FR 41228 (Aug. 3, 1993).
---------------------------------------------------------------------------

    Finally, it is important to note that NHTSA has historically taken 
the position that its evaluation of economic practicability does not 
consider the ability of the low volume manufacturer to absorb any 
potential civil penalties.\37\ This is because if NHTSA considers the 
ability to pay a civil penalty as part of economic practicability for 
an individual manufacturer, the resulting standard may be higher than 
the highest fuel economy level that the manufacturer could achieve. 
Considering the ability of a manufacturer to pay civil penalties would 
also not conserve any fuel, which would not appear to support EPCA's 
underlying purpose of energy conservation and would simply represent a 
transfer of money from the manufacturer to the U.S. Treasury. This is 
separate from EPCA/EISA's statutory prohibition on the consideration of

[[Page 39444]]

trading, transferring, or the availability of credits when setting 
maximum feasible standards,\38\ which the agency believes is also 
relevant when setting alternative standards for a low volume 
manufacturer at the maximum feasible level.\39\ In either case, NHTSA 
continues to believe that imposing an unavoidable additional cost on 
manufacturers (whether to pay the penalty, or, since the enactment of 
the credit trading program in EPCA/EISA, buy credits from another 
manufacturer) contravenes Congress' intent to establish maximum 
feasible standards for a manufacturer that the manufacturer can 
actually achieve.
---------------------------------------------------------------------------

    \37\ See, e.g., 44 FR 3710 (Jan. 18, 1979).
    \38\ 49 U.S.C. 32902(h).
    \39\ While 49 U.S.C. 32902(h) does not point directly to the 
exemption provision at 49 U.S.C. 32902(d), it does point to 49 
U.S.C. 32902(f), which outlines the factors that NHTSA must consider 
when ``deciding maximum feasible average fuel economy.'' NHTSA 
believes that when the agency carries out the directive in 49 U.S.C. 
32902(d)--to prescribe by regulation an alternative average fuel 
economy standard for the passenger automobiles manufactured by the 
exempted manufacturer that the Secretary decides is the maximum 
feasible average fuel economy level for the manufacturers to which 
the alternative standard applies--just as considering the 
manufacturer's ability to pay civil penalties would result in a 
higher standard than the manufacturer could actually achieve, 
forcing the manufacturer to buy credits would also result in a 
higher standard than the manufacturer could actually achieve.
---------------------------------------------------------------------------

    Next, NHTSA interprets ``the need of the United States to conserve 
energy'' as ``the consumer cost, national balance of payments, 
environmental, and foreign policy implications of our need for large 
quantities of petroleum, especially imported petroleum.'' \40\ In 
determining the impact that establishing an alternative CAFE standard 
would have on the need of the United States to conserve energy, NHTSA 
has historically taken two approaches. Originally, if the agency 
determined the low volume manufacturer could not meet a higher fuel 
economy standard than they requested--because it was not 
technologically feasible or economically practicable for them to do 
so--NHTSA concluded that denying the exemption or setting a higher 
alternative standard would not lead to any fuel savings.\41\ Similarly, 
if the manufacturer had already produced the vehicles for sale (in the 
case of a petition that was granted after the vehicles were built and 
sold), NHTSA concluded that denying the exemption or setting a higher 
alternative standard would not result in any fuel savings, and would 
relatedly have no effect on the need of the United States to conserve 
energy.\42\ In later years the agency attempted to quantify the de 
minimis impact of granting low volume manufacturer exemption petitions 
for illustrative purposes, by estimating the amount of additional fuel 
consumed by the exempted fleet over its operating lifetime.\43\

23, 2006).
---------------------------------------------------------------------------

    Finally, in considering the impact of other standards of the 
Government on fuel economy, NHTSA has historically looked at the weight 
impact of its own safety standards, as well as the Environmental 
Protection Agency's (EPA) greenhouse gas (GHG) and criteria pollutant 
emissions standards. NHTSA is aware that some manufacturers included in 
this proposed decision have received a final determination from EPA on 
alternative GHG standards for past model years,\44\ standards that are 
on average less stringent than EPA's large manufacturer standards, and 
invites comment on any new information on the impact of EPA's GHG 
standards on the manufacturer's ability to meet an alternative fuel 
economy standard that the agency should consider.

---------------------------------------------------------------------------

    The following section discusses technological feasibility and 
economic practicability individually for each manufacturer, as each 
manufacturer employs technology in a different manner to achieve 
different objectives. For some manufacturers that have several years of 
unanswered petitions, with several vehicle lines, the discussion of 
relevant information submitted in their petitions is necessarily longer 
than that of a manufacturer that produces only one vehicle type, or 
that only has outstanding petitions for a few model years. In addition, 
because low volume manufacturers can petition for alternative standards 
for periods of three model years at a time,\45\ some petitions docketed 
in support of this notice also include requests for alternative 
standards for MYs through 2024. Outstanding MY 2024 requests will be 
addressed in a subsequent notice.
---------------------------------------------------------------------------

    \45\ 49 CFR 525.9.
---------------------------------------------------------------------------

    Note also, low volume manufacturers generally submit two copies of 
their petition to NHTSA, one with confidential business information 
(CBI), and one without. CBI includes information like projected sales 
volumes for each vehicle, planned future technology application, and 
future vehicle models. The information presented below is taken from 
the non-CBI materials because even though some model years have passed 
(and some MY-specific information like actual production volumes ceases 
to be CBI after the model year has passed and that information becomes 
knowable), information may still be pertinent to future product plans 
or confidential sales strategy may have remained the same over time.
    To assess the impact of setting alternative standards at the levels 
proposed herein on the need of United States to conserve energy, NHTSA 
presents the calculations for all manufacturers together and separately 
by manufacturer. Similarly, the assessment of the effect of other 
standards of the Government on fuel economy is presented in a single 
section for all manufacturers.
i. Technological Feasibility and Economic Practicability
    NHTSA's regulations at 49 CFR 525.7 request that low volume 
manufacturers submit several pieces of information to assist NHTSA in 
assessing technologically feasible and economically practicable 
improvements for the manufacturer's fleet. This information includes a 
description of the technological means selected by the manufacturer for 
improving the average fuel economy of its automobiles to be 
manufactured in a model year, a chronological description of the 
manufacturer's past and planned efforts to implement the fuel-economy-
improving technology in its fleet, a discussion of the alternative and 
additional means considered but not selected by the manufacturer that 
would have enabled its passenger automobiles to achieve a higher 
average fuel economy than is achievable with the means it described, 
and in the case of a manufacturer that plans to increase the average 
fuel economy of its passenger automobiles to be manufactured in either 
of the two model years immediately following the first affected model 
year, an explanation of the reasons for not making those increases in 
the affected model year.
    As discussed above, the technologies manufacturers generally 
discuss in these exemption petitions include technologies for weight 
reduction and aerodynamic improvements, engine improvements, and 
transmission improvements. Manufacturers have also started using off-
cycle and air conditioning (A/C) efficiency improvement technologies, 
which fall within the scope of technologies that manufacturers should 
discuss in their petitions to the agency if a manufacturer plans to 
apply those technologies in an affected MY.

[[Page 39445]]

(a) Aston Martin Lagonda Limited (AML) MY 2008-2023 Vehicles
    Aston Martin Lagonda Limited (AML) is a sports car manufacturer 
whose product portfolio for the model years covered by this proposed 
decision include the DB9, DBS, DB11, Vantage, Virage, Rapide, and 
Vanquish, among others, in multiple engine and body configurations.
    For all model years covered by AML's petitions for alternative 
standards, AML only sold vehicles with V8 or V12 engines. With respect 
to ongoing engine improvements, AML stated that for MYs 2018 and later 
it is downsizing the V12 6.0-liter engine to 5.2 liters, resulting in 
reduced fuel use. Other engine technologies for the V12 engine that AML 
stated support a reduction in fuel use include turbocharging, reduced 
exhaust backpressure, stop-start, cylinder deactivation, electric 
thermostat with coolant flow management, and electric/hydraulic power 
steering. For the models that use the new 4.0-liter V8 turbocharged 
engine, like the new DB11 V8 and Vantage models, AML stated that 
similar technology additions helped to realize an additional fuel 
economy improvement.
    Starting with MY 2014, AML employed Bosch engine management systems 
(EMS) to realize fuel consumption improvements and CO2 
emissions reduction through use of other technology enablers such as 
start-stop, but due to the small size of the company the application of 
additional technologies will be over an extended period. According to 
AML's MY 2021 petition in June 2018, all vehicle models included the 
Bosch EMS. AML stated that the company is also investigating powerunit 
sourcing opportunities to increase vehicle efficiency, although there 
are very long lead time changes due to contractual agreements with 
suppliers and vehicle architecture modification requirements.
    Since MY 2008, AML's transmissions incorporate six-, seven-, or 
eight-speed technologies, and the seven-speed transmission incorporates 
a lightweight, low friction design. Starting in 2014, AML began 
replacing the previously-used 6-speed ZF automatic transmission with an 
8-speed ZF transmission in its vehicles with V12 engines. Per AML, the 
DB11 uses an enhanced version of the 8-speed ZF transmission coupled to 
a low loss higher ratio final drive to enable further downspeeding of 
the V12 engine, thereby enhancing its fuel economy capability. Future 
AML models will also use this 8-speed transmission.
    Each of AML's vehicles possesses a body and chassis configuration 
that is small, aerodynamic,\46\ and that makes extensive use of 
advanced lightweight materials. All major body and mechanical 
components of the Virage, DB9, DB11, and Vanquish models are either 
aluminum, magnesium alloy, or advanced lightweight composite materials, 
resulting in vehicles that are up to 600kg lighter than comparable in 
the same class of vehicles.\47\
---------------------------------------------------------------------------

    \46\ The reported aerodynamic drag coefficients for AML vehicles 
range from 0.33-0.34 for the early 2010s DB9, Virage, and Vantage 
models, to 0.37 for the MY 2020 DB11. Although current mass market 
vehicles have now achieved similar aerodynamic drag coefficients, 
for high performance vehicles desirable downforce to prevent rear 
end lift at high speeds and sufficient powertrain cooling needs 
limit further reductions.
    \47\ Likewise, AML stated the company has extensively used 
carbon fiber composite material in the vehicles' body panels. All 
AML models incorporate an all-alloy underbody structure that 
contributes only minimal weight, in addition to the bonnet and roof 
that are constructed from a lightweight alloy, while the front 
fenders, tailgate, and sills are produced from advanced composites. 
Aside from the vehicle body, the engine block design also decreases 
weight with use of aluminum material for components that are not 
loading points.
---------------------------------------------------------------------------

    In the late 2000s/early 2010s, AML considered using partial 
hydraulic/electric or full electric power assist steering (EPAS) 
technology that could improve fuel economy, however, it was rejected 
because of the scale of development needed for introduction. As 
mentioned above, AML's more recent vehicles include this technology. 
Similarly, in the early 2010s, AML considered using low friction 
lubricants in the V8 engines but rejected them on the basis that 10W60 
oil provided the oil-film thickness retention needed to protect the 
lead-free main bearings at elevated engine speeds. Since that time, 
with the introduction of the 5.2 liter V12 engine, AML has improved 
engine friction by adopting advanced engine oil lubrication and is 
continuously investigating use of other oil formulations for the 
future.
    AML noted in its petitions that its vehicles share underlying 
platforms and technologies, which impacts how fuel-economy improving 
technologies can be applied throughout its fleet. For example, AML 
introduced the ZF 8 speed automatic transmission in MY 2015 following 
four years of development to replace all 6-speed transmissions on V12 
models apart from the DB9. AML stated that this lead time was 
principally driven by the need for new tooled parts and a heavily 
revised engine and gearbox calibration.
    Next, AML stated that it is not able to manipulate its model mix. 
AML produces only one ``type'' of car, specifically what it 
characterizes as high performance/limited production. These vehicles 
all have what AML refers to as multi-cylinder large capacity power 
units, and in fact for model years that have already passed, AML has 
only sold vehicles with V8 or V12 power units in the U.S. market. In 
early petitions, AML projected that vehicles with the (relatively) more 
fuel efficient V8 engines would exceed sales of vehicles with the V12 
engines, however, that did not happen. AML observed that the V8 and V12 
vehicles appeal to different market segments and attempting to force 
more sales of vehicles with V8 engines was not feasible. Accordingly, 
when sales of the V8 models declined relative to projections, as 
compared to the V12 model, AML's achieved CAFE level was negatively 
affected. Over the model years that NHTSA considered in this proposed 
decision, AML projected that the balance of vehicle sales with V8 and 
V12 engines would vary in different model years.
    AML also stated that the company is limited to making technology 
improvements that are compatible with the basic design concept of its 
vehicles, i.e., high performance vehicles. AML stated in its petitions 
that it has taken all possible steps to maximize fuel economy within 
its existing vehicle range, with recent changes to engine, engine 
management, and transmission technology, that has resulted in 
incrementally improving fleet fuel economy. AML also stated that its 
lightweight and aerodynamic vehicle designs have shown that it has done 
as much as possible to improve its vehicles' fuel economy.
(b) Ferrari MY 2016-2018 and 2020 Vehicles
    Ferrari N.V. (Ferrari) is a small volume manufacturer of sports 
cars. Ferrari's product portfolio for the model years covered by this 
proposed decision includes GT cars (e.g., the GTC4Lusso and California 
T) and sports cars (like the F12 Berlinetta and LaFerrari, and 488 
Spider and 488 GTB) with a mix of V8 and V12 engines, in addition to 
its portfolio of limited series supercars, which include the LaFerrari 
Aperta, the F60 America, the F12tdf, GTC4LussoT, and 812 Superfast.
    With respect to powertrain technologies, Ferrari stated that it was 
developing new gasoline direct injection technology to target tailpipe 
emissions, in addition to a new turbocharged, downsized, and down-
speeded V8 engine family. Ferrari also stated that it is investigating 
engines with higher BMEP levels to improve thermal efficiency from 
better combustion, with

[[Page 39446]]

electric boosting to reduce turbo lag. Ferrari provided specific 
technology information on its MY 2015 California T grand tourer, 
showing that with the addition of a downsized engine and two 
turbochargers, the vehicle achieved an improved fuel economy value of 
18.7% over the previous model while still meeting its performance 
objectives. The MY 2014 V12 Limited Edition LaFerrari utilized a hybrid 
powertrain with a 120kW electric motor and an ultra-lightweight 
composite body to achieve a fuel economy of 17.6 mpg.
    Ferrari stated that the mix of vehicles it sells strongly affects 
its fleet average fuel economy, though substantial fuel economy 
improvements can be seen in each category of vehicles. In evaluating 
new vehicle technologies, Ferrari stated that it must consider 
maintaining the higher performance and unique driving experience of its 
vehicles, customer acceptance, and the impact on overall vehicle 
design. Additionally, manufacturing constraints may affect which new 
technologies Ferrari can adopt on its vehicles; Ferrari noted that 
moving from internal R&D to production vehicles is dependent on 
suppliers, and obtaining components from suppliers is more difficult 
for Ferrari than for larger companies, especially given the low volume 
of vehicles produced and the unique nature of the vehicles' design. The 
low volume of components required by the company may cause delays or 
project cancellations due to the inability of suppliers to produce 
components in a desired timeframe. Additionally, Ferrari stated that it 
had not had any assistance regarding vehicle components from Fiat or 
Fiat Chrysler when it was still associated with those organizations.
    Ferrari stated that even with a limited model mix and the need to 
provide customers with superior performance, handling, and luxury, the 
company targeted a fuel economy improvement of 17.4% for its fleet 
average fuel economy for MY 2018 as compared to MY 2014. Ferrari stated 
that it planned to improve its fleet fuel economy in each of the model 
years covered by its petitions.
    Ferrari also initially requested an exemption for its MY 2019 
vehicles, but subsequently notified NHTSA that it produced more than 
10,000 passenger automobiles globally in 2019 and therefore was not 
eligible for small volume manufacturer status. Accordingly, NHTSA did 
not consider Ferrari's original MY 2019 request in this notice.
    However, Ferrari has requested an exemption for its MY 2020 
vehicles, expecting sales to be below the 10,000 passenger automobiles 
globally. The drop in sales is anticipated due to the effects of the 
COVID-19 public health emergency.
(c) Koenigsegg Automotive AB MY 2015, 2018-2023 Vehicles
    Koenigsegg Automotive AB (Koenigsegg) is a low volume manufacturer 
of high-performance vehicles. For the model years covered by this 
proposed decision, Koenigsegg produced the Agera model for 2015 and 
2018, the Regera model for 2019-2021, the Jesko model for 2022-2023, 
and the Gemera model for 2023.
    Koenigsegg vehicles use smaller displacement engines than many 
other specialty manufacturers; the company stated that where other 
similarly situated manufacturers often use 6 liters or larger 
displacement 10- or 12-cylinder engines, the Koenigsegg engine is a 
relatively small 5-liter V8 engine that utilizes twin turbochargers to 
facilitate vehicle performance. Koenigsegg also uses lightweight 
materials to build its vehicles; carbon fiber is used not only for the 
body panels, but for structural parts as well. Additionally, starting 
with MY 2019, the company offers only a hybrid drivetrain, consisting 
of a conventional combustion engine and three electric motors. That 
hybrid drivetrain was not introduced onto MY 2015 and MY 2018 vehicles 
because of budget and staff limitations.
    Koenigsegg stated that it was not possible to improve its fuel 
economy level in MYs 2015 and 2018-2021 by shifting its fleet mix 
because the company only offered one vehicle configuration. 
Additionally, for model years 2022 and 2023, the vehicle footprints are 
increasing in size for the new vehicle models. Koenigsegg stated that 
its budget for research and development into fuel economy improving 
technologies is limited because of its small size. Other economic 
practicability concerns relevant to this proposed decision include 
Koenigsegg's statement that an obligation to meet higher CAFE standards 
than requested would ``jeopardize [its] position as a world class 
leader of hyper cars.''
(d) McLaren Automotive MY 2012-2023 Vehicles
    McLaren Automotive is a small volume manufacturer of high-
performance vehicles. The vehicles covered by McLaren's petitions 
include the MP4-12C, P1, 570S/570GT, and 720S, among others.
    McLaren's independently-developed vehicle models began in 2011 with 
the McLaren MP4-12C, which utilized McLaren's independently-developed 
engine, the M838T. The M838T is a 3.8 liter downsized, turbocharged 8-
cylinder engine that employs technologies including variable valve 
timing to optimize engine efficiency, secondary air injection, and 
electronically controlled twin thermostats. The engine also uses 
Nikasil-coated aluminum liners for further weight reduction. McLaren 
stated the valve timing on the M838T has been calibrated for best fuel 
economy under typical road driving speeds and loads, within the 
limitations of acceptable combustion stability. From optimizing the 
M838T prototype engine to pre-production engine valve timing, McLaren 
realized a 4-5% specific fuel consumption reduction. The M838T also 
uses friction reduction technology including reduced diameter bearing 
journals, the Nikasil-coated cylinder liners mentioned above, low 
friction piston skirt coating, superfinished finger followers, and 
coated valves in the valvetrain. The piston ring pack has been 
developed to meet oil consumption targets with minimum ring tension, 
and the use of a dry sump system, allows reduced churning losses in the 
crankcase. McLaren uses synthetic Mobil 0W/40 oil in its vehicles, and 
stated that the advantages to moving to bespoke oil for its vehicles is 
limited; however, McLaren stated that it is investigating other 
advanced engine oil formulations.
    McLaren's P1 vehicle is powered by an upgraded version of its M838T 
powertrain in parallel with an electric motor, and the vehicle can 
operate in either hybrid or electric-only mode. The motor also allows 
for energy recovery through regenerative braking. Accordingly, the P1 
has achieved an increase in fuel economy over the previous vehicle, the 
MP4-12C, while also increasing power.
    The M838T engine is coupled to a 7-speed dual clutch transmission, 
which McLaren refers to as its ``Seamless Shift'' dual clutch gearbox 
(SSG), and which the company designed to respond to demand for a 
``mechanical package that resulted in not only reduced weight and 
dynamic control for the entire vehicle, but also improved fuel 
consumption and CO2 emissions.'' McLaren stated that the 
gear ratios have been optimized for acceptable vehicle performance 
while maximizing fuel economy,\48\ and in the transmission's base mode, 
``auto normal,'' the shift

[[Page 39447]]

points are optimized to provide maximum powertrain efficiency and fuel 
economy.\49\ McLaren has explored transmission loss reductions, using 
hardware to significantly improve losses from the first prototype 
transmission and final validation prototypes. A wide default park 
position for the shift clutches also allows for reduced friction 
levels, reduced cooling flow to the clutches, contributing to 
efficiency at idle. Because there is some performance trade-off for 
this park position, the vehicle uses an adaptive strategy to detect 
when a higher performance level is required, returning to the low 
friction park position once the high-performance demand has subsided. 
McLaren also stated that the transmission lubricants have been 
optimized to provide the best compromise between fuel economy and 
transmission life/service intervals.
---------------------------------------------------------------------------

    \48\ Additionally, McLaren stated that the maximum speed of the 
MP4-12C is achieved in 6th gear, leaving 7th gear as a true 
``overdrive'' gear intended for maximum fuel efficiency.
    \49\ McLaren stated that the company has conducted extensive 
development work to ensure that the default shift schedule has been 
optimized to ensure the best possible fuel economy: ``The high 
levels of torque available at low engine speeds have been exploited 
to improve fuel economy. The engine idle speed has been reduced to 
600rpm to minimise the fuel consumption when in this condition. If a 
very high level of performance is requested by the driver, the shift 
schedule will adapt to this request before returning to the low 
engine speed, maximum fuel economy schedule, once the driver demand 
is reduced to lighter load driving. This adaption will be completed 
after just 20 seconds of light load driving. If the driver is 
holding a constant speed around 50kph/30mph then this will trigger a 
shortcut and the adaption will be complete within just 4 seconds.''
---------------------------------------------------------------------------

    All of McLaren's vehicles utilize a lightweight carbon fiber 
chassis that McLaren has termed the Carbon MonoCell, with the 12C 
MonoCell weighing less than 175 pounds. Other mass reduction 
opportunities that McLaren has implemented include brakes with forged 
aluminum hubs, reduced exhaust path length, airflow-assisted airbrake 
deployment, reduced wheel weight, rear-mounted engine cooling radiators 
to minimize pipework and the fluid contained within, a downsized engine 
coupled to a lightweight transmission, halogen-free compressed wiring, 
and a Li-ion battery.
    For aerodynamic improvements, McLaren has increased the MP4-12C 
down force while achieving a reduction in the coefficient of drag 
relative to the Mercedes SLR McLaren. Techniques used to achieve this 
reduction include a more efficient vehicle shape, careful control of 
vehicle cooling air, and extensive use of under floor guide vanes to 
control wheel wakes while producing downforce with little or no drag 
penalties.
    Other commonly employed vehicle technologies that McLaren has 
utilized to reduce parasitic losses include an electrically powered 
hydraulic steering system, which provides fuel efficiency improvements 
over a conventional engine-driven hydraulic pump by removing the need 
to continually drive the pump when the pressure is not required. 
McLaren has also made electric load improvements by using high 
efficiency lamps and series/parallel fan control.
    With respect to economic practicability, McLaren noted that it 
invested significantly in the M838T engine, and as a low volume 
manufacturer with relatively low sales volumes, a return on investment 
must come from carefully considered platform engineering and an 
extended lifecycle for the base powertrain. The projected trend for 
McLaren's market sector is continued increases in rated power; the 
company predicted that a sustained reduction in CO2 (and 
accordingly, an increase in fuel economy) would be challenging. McLaren 
stated that the company continues to conduct powertrain research and 
development to support future emissions and CO2 reductions. 
However, McLaren stated that currently, there are no other further fuel 
economy improvements that the company can adopt that are compatible 
with the basic design concept of its high-performance sports cars. 
Similarly, McLaren stated that the company has no opportunity to 
improve fuel economy by changing its model mix because all of its 
vehicles share a common platform, all using variants of the same power 
plant.
    As for future fuel economy improvements, McLaren stated that moving 
forward, they have planned a range of other models that will allow the 
company to introduce new, innovative technologies designed to improve 
efficiency even further. McLaren in 2016 stated that the company 
planned to implement hybrid technology on 50% of its fleet by 2022, 
with a quarter of planned investment revenue slated for research and 
development of new technologies. In 2020, McLaren stated that the 
company would implement hybrid technology on 100% of its Sports Series 
and Super Series vehicles by 2025.
(e) Mobility Ventures MY 2014-2016 MV1
    Mobility Ventures is a wholly-owned subsidiary of AM General LLC 
(``AM General''). AM General is a private company headquartered in 
South Bend, Indiana. AM General produces light tactical vehicles for 
the military as well as commercial vehicles, both as an original 
equipment manufacturer (OEM) and as a contract manufacturer.\50\
---------------------------------------------------------------------------

    \50\ Vehicles manufactured and certified by AM General in the 
past, such as the road-legal variant of the Hummer, were likely not 
passenger automobiles or non-passenger automobiles subject to the 
CAFE program, and thus would not have needed to apply for exemption 
from CAFE standards.
---------------------------------------------------------------------------

    Prior to forming Mobility Ventures in late 2013, AM General 
contracted with the now-defunct Vehicle Production Group LLC (``VPG'') 
to assemble their MV-1 vehicle at AM General's Commercial Assembly 
Plant in Mishawaka, Indiana. The MV-1 is a vehicle specifically 
engineered from the ground up to address the unique requirements and 
limitations of wheelchair users and other people with disabilities. 
Production of the VPG MV-1 began in 2011 and ended in February 2013 
when VPG ceased operations. In September 2013, AM General acquired the 
assets of VPG and formed Mobility Ventures to assume engineering, 
production, and distribution of the MV-1. Production of the MV-1 
resumed under the Mobility Ventures brand in March 2014. Production of 
the MV-1 ceased in late 2015, with MY 2016 being the final model year.
    In its petition, Mobility Ventures listed and described several 
fuel-saving technologies that it applied to its vehicles for MYs 2014-
2016 including engine and transmission technologies. Mobility Ventures 
noted that, ``after acquiring the assets of VPG in 2013, Mobility 
Ventures put the MV-1 into production without modifying the vehicle 
from VPG's 2012 model year configuration,'' due to time constraints. 
For MY 2014, Mobility Ventures offered a compressed natural gas (CNG) 
variant of the 4.6L V8 engine which achieved a fuel economy value of 
114.7 mpg, substantially higher than the 18.4 mpg achieved by the 
gasoline-powered variant. Starting with MY 2015, Mobility Ventures 
retired the 4.6L V8 engine in favor of a more efficient 3.7L V6 engine. 
Also for MY 2015, Mobility Ventures replaced the 4-speed transmission 
with a more efficient 6-speed transmission. Implementation of this 
downsized engine and more advanced transmission resulted in a 9.8% 
increase in fuel economy for the MY 2015 MV-1 as compared to the 
gasoline-powered MY 2014 MV-1. The MV-1 retained the MY 2015 
configuration for MY 2016.
    Mobility Ventures did not consider any changes for the MY 2014 MV-1 
since it elected to resume MV-1 production without delay following its 
acquisition of VPG in late 2013. Mobility Ventures planned to offer a

[[Page 39448]]

CNG version of the MV-1 for MY 2015. However, CNG calibration issues 
arose in transitioning to the more fuel efficient 3.7L V6 engine. 
Mobility Ventures considered technical solutions proposed by the fuel 
injector manufacturer but could not justify the substantial added cost 
given the weak demand for the CNG version of the vehicle.
(f) Pagani Automobili S.p.A MY 2014 and 2016-2023 Vehicles
    Pagani Automobili S.p.A. (Pagani), formerly Modena Design S.p.A., 
is an Italian corporation formed in 1991 and owned by the Pagani 
family. Pagani began manufacturing Pagani-brand sports cars in 1999, 
first producing the Zonda, then Huayra,\51\ both in very low volumes. 
For the model years covered by Pagani's petitions, the company's 
product portfolio includes the Huayra (C9), Huayra BC (C9N), and Huayra 
Roadster (C9R). The company estimated that it had a total production 
capacity of no more than 50 vehicles per year, with approximately 20 of 
those vehicles built to U.S. specifications.
---------------------------------------------------------------------------

    \51\ The corresponding model numbers for vehicles covered by 
this petition are C8 and C9. As of the date that Pagani submitted 
its MY 2012-2014 petition, the C9 had not yet been named Huayra.
---------------------------------------------------------------------------

    Pagani's first vehicle, the Zonda, was a high-performance sports 
car powered by a Mercedes-Benz 12-cylinder engine. The Huayra, the 
vehicle replacing the Zonda, received a new engine, the M158 engine, 
which was more powerful than the previous engine but also smaller, 
further reducing weight and increasing efficiency. Pagani stated in its 
MY 2015-2017 petition that the M158 engine was homologated to meet the 
strictest environmental regulations, which at that time were EU5 and 
LEV2. Additionally, despite the increase in power compared to other 
Mercedes-AMG V12 engines developed for Pagani, the engine has reduced 
CO2 emissions and fuel consumption, ``to make the Pagani 
Huayra class leading amongst 12 cylinder sports cars with values that 
are respective of much smaller vehicles in the market.'' Pagani's MY 
2018-2020 petition also stated that a new developed engine is expected 
for introduction in MY 2018.
    Pagani stated in its MY 2012-2014 petition that the Huayra makes 
extensive use of lightweight materials, including carbon fiber in the 
chassis and panels, and chromoly steel space frames. Pagani stated in 
its MY 2015-2017 petition that the central monocoque on the Huayra had 
been updated to an entirely new design made from carbontitanium, and 
structural and non-structural weight reduction strategies like 
integrating all ventilation air ducts into the monocoque's structure 
contributed to the vehicle's weight of 1,350 kg (2976.24 lbs), making 
the Huayra ``the lightest sports car in its class.'' Pagani stated that 
the Huayra design optimizes aerodynamics to achieve a coefficient of 
drag value of 0.35, which also allows for greater efficiency. Finally, 
the Huayra employs low rolling resistance Pirelli P Zero tires to 
reduce CO2 emissions and fuel consumption.
    Pagani stated that the unique nature of the company's product line 
does not lend itself to high fuel economy values, and accordingly there 
are no additional fuel economy improvements that it could adopt that 
are compatible with the basic design concept of a traditional sports 
car. Similarly, Pagani stated that it cannot improve its fuel economy 
by changing its model mix because it only sells one vehicle model in 
the United States, which uses the Mercedes-Benz engine. Because Pagani 
does not produce its own engine, the company stated that it is 
constrained in making additional improvements to the vehicle 
powertrain. Beyond the technologies described above, Pagani stated that 
there are no further fuel economy improvements for the company to adopt 
that are compatible with the basic design concept of its vehicles.
(g) Spyker Automobielen B.V. MY 2008-2010 Vehicles
    Spyker Automobiles produces limited-production sports cars, built 
to individual order.\52\ The vehicles covered by Spyker's MY 2008-2010 
petition include different variants of its C8 vehicle.\53\
---------------------------------------------------------------------------

    \52\ At the time that the entity that produced Spyker vehicles 
petitioned NHTSA for alternative standards, that entity was Spyker 
Automobielen B.V. That entity is now Spyker N.V., however it does 
not seem that Spyker has produced vehicles for sale in the U.S. 
market from the time of the 2008-2010 petition.
    \53\ At the time of its petition, Spyker was also planning to 
produce a Super Sport Utility Vehicle (SSUV) and mentioned that 
vehicle in their petition. However, 49 U.S.C. 32902(d) limits the 
applicability of an exemption to passenger automobiles produced by 
the manufacturer requesting the exemption.
---------------------------------------------------------------------------

    Spyker's vehicle uses a LEV V8 powertrain from the Audi A8 coupled 
with a Bosch ME-7 engine management system. Spyker stated that this 4.2 
L Audi V8 engine is the most advanced engine available to a small 
vehicle manufacturer seeking an engine from an outside source. Spyker 
stated that its vehicles are both lightweight and aerodynamic; the 
chassis is made of aluminum and the vehicle in total weighs in at 1346 
kg (2967 pounds). The coefficient of drag of the vehicle is 0.41 with 
the roof off, and 0.38 with the roof on.
    Spyker stated that the high-performance nature of its product line 
generally does not lend itself to high fuel economy values, and the 
company is not able to manipulate model mix because the company was 
created to sell limited numbers of high-performance automobiles. 
Accordingly, Spyker stated that there is no room for CAFE changes based 
on marketing actions. Spyker also stated that it has no opportunity to 
improve fuel economy by changing its model mix because it would only 
export three high performance models to the United States in MYs 2008-
2010, all using the Audi V8 or V12 engines. Spyker also stated the 
company had invested millions of dollars (at the time of the MY 2008-
2010 petition) in design, development, homologation, and the start of 
production, and the company is financially constrained in making 
additional fuel economy improvements because of the large investment in 
start-up and producing new models. In sum, Spyker stated that producing 
more fuel-efficient models or making existing configurations 
significantly more fuel efficient is not possible.
ii. The Need of the United States To Conserve Energy
    Many of the manufacturers considered in this notice noted that they 
were not unmindful of energy issues facing the United States today, 
including both energy conservation and climate change. Several 
manufacturers noted however, that the extremely low sales volumes of 
their vehicles, coupled with the fact that, in the case of many high-
performance sports cars, they are ``almost exclusively used as a second 
or third car (and hence infrequently),'' \54\ meant that these vehicles 
had a ``virtually immeasurable'' effect on U.S. energy consumption.\55\ 
As discussed further below, some manufacturers also submitted 
additional data estimates on how many miles their vehicles are driven 
per year, or estimates of how much fuel their fleet of vehicles is 
estimated to consume over time, and the agency confirmed these 
estimates with an independent evaluation of vehicle miles travelled 
(VMT) data performed for this notice.
---------------------------------------------------------------------------

2023.

---------------------------------------------------------------------------

    As mentioned above, when independently evaluating the impact that 
establishing an alternative CAFE

[[Page 39449]]

standard would have on the need of the United States to conserve 
energy, NHTSA has historically taken two approaches. For several years, 
the agency categorically concluded that if it had already determined 
that it would not be technologically feasible or economically 
practicable for the low volume manufacturer to achieve a higher fuel 
economy standard than requested, denying the exemption or setting a 
higher alternative standard would not have had any effect on the need 
of the United States to conserve energy.\56\ In later years the agency 
attempted to quantify that de minimis impact for illustrative purposes, 
by estimating the amount of additional fuel consumed by the exempted 
fleet over their operating lifetime.\57\
---------------------------------------------------------------------------

    \56\ See, e.g., 54 FR 40689 (Oct. 3, 1989).
    \57\ See, e.g., 61 FR 46756 (Sep. 5, 1996), 71 FR 49407 (Aug. 
23, 2006).
---------------------------------------------------------------------------

    In brief, the estimated amount of additional fuel consumed by the 
exempted fleet over its operating lifetime is a function of the 
difference between the manufacturer's actual CAFE standard and their 
requested alternative standard multiplied by the manufacturer's 
estimated U.S. production volume, multiplied then by an estimate of the 
total miles these vehicles could travel as an active part of the 
fleet.\58\ The resulting difference is then divided by the average 
number of gallons that the total U.S. automotive fleet uses.\59\ The 
final value shows the fleet's additional gallons of fuel use as a 
percentage of total U.S. automotive fuel use.
---------------------------------------------------------------------------

    \58\ NHTSA estimated the lifetime miles for vehicle classes as 
part of the SAFE Final Rule analysis. See SAFE Final Rule 
``paramters_ref.xlsx'' file, available for download at https://www.nhtsa.gov/corporate-average-fuel-economy/compliance-and-effects-modeling-system.

Review March 2020, Table 3.7c Petroleum Consumption: Transportation 
and Electric Power Sectors, available at https://www.eia.gov/totalenergy/data/monthly/pdf/mer.pdf.
---------------------------------------------------------------------------

    Unique to the analysis for this proposed action is that for model 
years that have already passed, for which NHTSA has final verified fuel 
economy values from EPA or final data submitted to EPA by 
manufacturers, those values are used instead of the proposed 
alternative standard. In a majority of cases, the manufacturers 
achieved a higher fleet fuel economy value than they requested for a 
given model year.
    Additionally, because projected U.S. production volumes for some 
fleets are still CBI at this time, or because NHTSA does not have final 
production data from EPA for some completed model years, NHTSA averaged 
each manufacturers' latest three years of verified production data to 
present estimates of potential future fuel use for those model years. 
NHTSA considered assuming that every manufacturer would produce the 
maximum 10,000 vehicles in MYs 2019 and later, or that each 
manufacturer would produce 5,000 vehicles in MYs 2019 and later, 
although these assumptions were not supported by historical data. NHTSA 
seeks comment on this approach, in addition to any alternative 
assumptions that the agency should employ in estimating the amount of 
additional fuel consumed by a fleet granted an alternative CAFE 
standard. Note again, these projections are only used to estimate the 
potential future fuel use of a manufacturer's fleet; a fleet's actual 
fuel use is dependent factors like an individual vehicle owner's 
driving patterns. As discussed below, many of the vehicles considered 
in this notice are driven infrequently, if at all.
    For the quantitative estimate presented today, NHTSA also developed 
new assumptions about low volume vehicle lifetime mileage that more 
accurately captures how some low volume vehicles are driven.\60\ For 
reference, the Federal Highway Administration's (FHWA) 2017 National 
Household Travel Survey (NHTS) best available estimate for average 
miles driven per vehicle is 11,128 miles per year for the category of 
vehicle that includes automobiles, cars, and station wagons.\61\ 
NHTSA's new calculated yearly VMT for high performance vehicles is 
2,543 miles per year. Note, as discussed below, that NHTSA used the 
FHWA's 2017 NHTS best available VMT estimate for cars for Mobility 
Ventures' fleet, as the agency does not believe that the driving 
patterns of mobility vehicles are accurately represented by the data 
used to calculate an average yearly VMT value for high performance 
vehicles. The agency seeks comment on this approach, in addition to any 
other data or information on the driving patterns and mileage schedules 
of vehicles used to transport wheelchair bound or otherwise mobility 
impaired individuals.
---------------------------------------------------------------------------

    \60\ Historically, low volume manufacturer petitions for 
exemption from CAFE standards have covered luxury vehicles, exotic 
high-performance vehicles, and vehicles exclusively designed to be 
used for transporting the wheelchair bound or other mobility-
impaired individuals.
    \61\ See Developing a Best Estimate of Annual Vehicle Mileage 
for 2017 NHTS Vehicles, available at https://nhts.ornl.gov/assets/2017BESTMILE_Documentation.pdf.
---------------------------------------------------------------------------

    To estimate an average yearly VMT schedule for high performance 
vehicles, NHTSA consulted an IHS/Polk dataset that includes more than 
74 million unique odometer readings across 16 model years (2000-2015). 
NHTSA used over 10,000 odometer readings from vehicles produced by 
Aston Martin, Ferrari, and McLaren from MY 2000 to MY 2014. 
Specifically, NHTSA used the average odometer reading for vehicles of 
each manufacturer, model, and model year, and the average age of the 
vehicle in calendar year 2014 (when the majority of odometer readings 
occurred). NHTSA then divided the average odometer reading by the 
average age for each vehicle to arrive at an estimate of average miles 
traveled per year of use. Averaging all the unique make, model, and 
model years for which there is data (approximately 200 unique 
combinations), resulted in an average usage of 2,543 miles per year.
    Although this is a relatively small sample that only considers 
manufacturers for which there is readily-available data, it more 
closely tracks what low volume manufacturers (specifically in this case 
of what could be considered high performance vehicles) claim the 
impacts of their vehicles would be on overall fuel use. For example, 
AML's MY 2019 petition (and other manufacturers have shared similar 
sentiments) stated that their vehicles' impact on energy consumption is 
de minimis, ``not only because of the tiny volume of cars, but also 
because the vehicles tend to be used very infrequently (as a second or 
third car) and therefore have a very low VMT (vehicle miles travelled) 
value per annum.'' Similarly, Pagani stated that, in fact, ``[s]ome 
customers choose to not drive the cars at all and view the cars as 
investments to be stored for future sale. Most others will choose to 
drive the car sparingly as a weekend trophy car.'' More recently, in 
its MY 2022 petition, AML stated that ``AMLs current understanding is 
that VMT [for its vehicles] is in the order of 2500 miles per annum.''
    We seek comment on this new approach, in addition to any other data 
or information on yearly VMT for vehicles that would generally qualify 
under NHTSA's low volume manufacturer provision. If commenters believe 
that a higher VMT assumption would be appropriate for making this 
calculation, it would be most helpful to the agency for commenters to 
provide specific data or citations underlying that belief, ideally data 
that could be made public. Additionally, as mentioned above, NHTSA did 
not believe that it was appropriate to use the calculated value for 
high performance vehicles for the Mobility Ventures fleet, as odometer

[[Page 39450]]

readings from high performance sports cars would likely not be 
representative of the average usage of mobility vehicles. NHTSA seeks 
comment on any data or information that would help to inform the 
agency's yearly VMT schedule for these vehicles.
    NHTSA estimates that the additional fuel consumed by the LVM fleets 
at the proposed alternative standards level is as follows:

iii. The Effect of Other Standards of the Federal Government on Fuel 
Economy
    NHTSA has determined that ``other motor vehicle standards of the 
Government'' that affect fuel economy include its own safety standards 
as well as EPA's emissions standards, which include criteria pollutant 
and now greenhouse gas ((GHG), which include CO2, 
N2O, CH4, and hydrofluorocarbons) emissions 
standards. While NHTSA regulates fuel economy and EPA regulates GHGs, 
and has done so sometimes in joint rules, differences in the agencies' 
statutory authorities make it so that each agency is required to make 
an independent judgment about the level of standards that is 
appropriate.\63\
---------------------------------------------------------------------------

    \62\ See U.S. Energy Information Administration Monthly Energy 
Review March 2020, Table 3.7c Petroleum Consumption: Transportation 
and Electric Power Sectors, available at https://www.eia.gov/totalenergy/data/monthly/pdf/mer.pdf. This includes an average 
estimate of 8.9 million barrels/day of motor gasoline consumed by 
vehicles in the United States.
    \63\ See 85 FR 24174, 25137 (April 30, 2020).
---------------------------------------------------------------------------

    This is the first time that NHTSA has had the opportunity to 
consider EPA's small volume manufacturer GHG standards in the context 
of CAFE low volume petitions for exemption. Just as there are 
differences in the agencies' statutory directives that require 
programmatic differences between the fuel economy and greenhouse gas 
emissions light-duty vehicle programs, differences exist between each 
agency's low or small volume manufacturer exemption program. EPA's 
small volume manufacturer regulations, finalized in 2012,\64\ defined 
the process for exemptions from GHG standards \65\ differently from the 
NHTSA program by expanding applicability to light trucks, and lowering 
the eligibility requirements to only 5,000 vehicles produced in the 
United States.\66\ For NHTSA's program, both the 10,000 vehicle 
worldwide production limit on eligibility and sole applicability to 
passenger cars were terms prescribed by Congress in the 1970s.\67\

    \65\ 77 FR 62624, 62789 (Oct. 15, 2012).
    \66\ To be eligible for alternative standards established under 
the EPA program, the manufacturer's average sales for the three most 
recent consecutive model years must remain below 5,000. If a 
manufacturer's average sales for the three most recent consecutive 
model years exceeds 4999, the manufacturer will no longer be 
eligible for exemption and must meet applicable emission standards 
starting with the model year. See 40 CFR 86.1818-12(g)(1). In 
contrast, as discussed above, 49 U.S.C. 32902(d)(1) makes clear the 
exemption applies to manufacturers that manufacture worldwide fewer 
than 10,000 passenger automobiles in the model year 2 years before 
the model year for which the application is made, and in the 
applicable model year. In addition, 49 U.S.C. 32902(d)(1)(B) makes 
clear the exemption and alternative standard only applies to 
passenger automobiles.

    Three manufacturers considered in this notice (Aston Martin, 
Ferrari, and McLaren) recently received an alternative low volume 
standard under the EPA small volume program for vehicles manufactured 
in MYs 2017-2021.\68\ For the first four model years of the program, 
MYs 2017-2020, EPA proposed and adopted the alternative standards 
requested by the manufacturers. For MY 2021, EPA finalized MY 2021 
standards for McLaren reflecting 3 percent year-over-year reductions 
from a MY 2017 baseline year.\69\

    NHTSA must set alternative standards at the maximum feasible 
average fuel economy level for the manufacturer to which the 
alternative standard applies.\70\ This means that, as discussed further 
below, NHTSA believes that the agency cannot set alternative standards 
for a manufacturer for past model years at the level that the 
manufacturer requested, if that level is lower than the fuel economy 
level than the manufacturer actually achieved. In fact, it is 
frequently the case that the manufacturers achieved a higher fuel 
economy value than they requested. NHTSA believes that, accordingly, 
the requested fuel economy value is not the maximum feasible fuel 
economy level that the manufacturer could have achieved in that model 
year, and is proposing to set standards at the fuel economy values that 
manufacturers achieved for past MYs.

    EPA's final rule also stated that in determining GHG standards for 
some manufacturers in MY 2021, EPA considered that those standards can 
be met ``through the use of credits, including air conditioning and 
off-cycle credits, and the use of program flexibilities including 
credit carry-forward and credit carry-back within the lead time 
available.'' \71\ As discussed above, NHTSA does not consider the 
availability of credits when prescribing a maximum feasible average 
fuel economy standard under the low volume CAFE exemption program. In 
addition, in NHTSA's program, the

[[Page 39451]]

additional fuel economy benefit from air conditioning and off-cycle 
technology is added to a vehicle's fuel economy value, and is not a 
``credit'' that can be traded or transferred. Accordingly, as discussed 
above, a manufacturer that plans to use air conditioning and off-cycle 
technology should include any anticipated benefit from those 
technologies in the projected fuel economy value for each vehicle 
configuration as required by 49 CFR 525.7(f).

    NHTSA invites comment on any new information on the impact of EPA's 
GHG standards on a manufacturer's ability to meet an alternative fuel 
economy standard that the agency should consider.
    In regards to the impact of vehicle safety standards on CAFE 
values, AML stated that Federal Motor Vehicle Safety Standard (FMVSS) 
No. 214, Side Impact Protection, FMVSS No. 216, Roof Crush Resistance, 
FMVSS No. 226, Occupant Ejection Mitigation, and FMVSS No. 301, Fuel 
System Integrity, could have potential adverse impacts on its vehicles' 
achieved fuel economy levels, requiring increased mass to body and 
frame structures. Additionally, AML stated that it must consider the 
Pedestrian Protection requirements as proposed in the UN ECE Global 
Technical Regulation (GTR) No. 9 due to economies of scale. GTR No. 9 
would require increased deformation resistance to body and frame 
structures, which translate into additional weight.\73\
---------------------------------------------------------------------------

    \73\ To the extent that GTR No. 9 adds additional weight and AML 
has modified its entire fleet of production vehicles based on 
economies of scale to meet that standard, NHTSA understands that is 
factored into AML's assessment of the maximum feasible fuel economy 
level that its fleet could achieve.
---------------------------------------------------------------------------

    Ferrari stated that FMVSS No. 216, Roof Crush Resistance, FMVSS No. 
226, Occupant Ejection Mitigation, and FMVSS No. 214, Side Impact 
Protection, affect vehicle weight and aerodynamics, and other aspects 
of vehicle design. Ferrari also stated that they face challenges 
regarding compliance with the EPA and California Tier 3 tailpipe and 
evaporative emissions standards.
    Koenigsegg stated that the Federal motor vehicle standards 
regarding outside rear view mirrors have a significant effect on fuel 
economy, and that if outside rear view mirrors are replaced by camera 
systems, fuel economy will improve significantly.
    McLaren cited FMVSS No. 214, Side Impact Protection, FMVSS No. 216, 
Roof Crush Resistance, and FMVSS No. 301, Fuel System Integrity, as 
safety standards that have impacts on McLaren's achievable fuel 
economy. McLaren also stated that crashworthiness standards generally 
tend to decrease fuel economy, since they can preclude, in some 
instances, the use of lighter-weight components. McLaren additionally 
cited EPA's Tier 3 emissions rule as a requirement that would demand 
resources (both financial and personnel) and a balancing of priorities 
for the company to comply with all government standards.
    Mobility Ventures did not identify any other motor vehicle 
standards that affect the fuel economy achieved or achievable by the 
MV-1.
    Pagani stated that the company's small size limits the amount of 
resources it can apply to comply with both the mandatory safety and 
emissions standards and fuel economy requirements (citing NHTSA's 
proposed and final decisions for Spyker's MY 2006 and 2007 exemption 
request).\74\ Similarly, Pagani cited NHTSA's proposed decision for 
DeTomaso Automobiles' MY 2000 and 2001 vehicles for the proposition 
that crashworthiness standards can generally tend to reduce achievable 
CAFE,\75\ since they preclude, in some instances, the use of lighter 
weight components. Pagani stated that other safety standards that would 
demand the company's resources, and that could have weight and fuel 
economy consequences, include upgraded FMVSS No. 301, Fuel System 
Integrity requirements, upgraded FMVSS No. 214, Side Impact Protection, 
and upgraded FMVSS No. 216 Roof Crush Resistance.

    Spyker stated in its petition for MYs 2008-2010 that California's 
emissions standards will apply to the company in MY 2006, and the Tier 
2-LEV II exhaust standards are applicable in 2007. Accordingly, the 
company's limited engineering resources would have to be expended to 
comply with those more stringent standards. With respect to safety, 
Spyker stated that crash-worthiness standards tend to reduce achievable 
CAFE because they preclude, in some instances, the use of lighter-

[[Page 39452]]

weight components. Spyker also stated that smaller companies with 
limited resources must give priority to compliance with safety 
standards. Spyker had until June 2008 to develop FMVSS No. 208, 
Occupant Crash Protection compliant advanced air bags (under a NHTSA 
temporary exemption), which the company stated would add additional 
weight, and Spyker stated that FMVSS No. 301, Fuel System Integrity 
would also demand additional resources.
    To determine the additional weight that federal motor vehicle 
safety standards would have on these vehicles, to determine the impact 
of the standards on fuel economy, NHTSA used published estimates from 
the MYs 2017-2025 Light-Duty Vehicle Greenhouse Gas Emission Standards 
and Corporate Average Fuel Economy Standards Final Regulatory Impact 
Analysis (FRIA).\76\ Table IV-3a in the FRIA shows estimated weight 
increases for each FMVSS that would become effective between MY 2008 
and MY 2018 for passenger vehicles and light trucks, comparing MY 2025 
to the MY 2008 baseline fleet.\77\ The passenger car values are 
reproduced below.

weight for passenger cars between the two fleets is 5.13 pounds 
(32.31 added pounds for the 2008 fleet and 27.18 added pounds for 
the 2010 fleet). NHTSA believes that the 5.13 pound difference 
between the two estimates is trivial; however, the agency decided to 
use the more conservative 2008 fleet estimates for this analysis.

    As NHTSA stated in the FRIA, these weight estimates, which are 
based on cost and weight tear-down studies of a few vehicles, cannot 
possibly cover all the variations in a manufacturer's fleet. Rather, 
these represent rough averages of potential per-vehicle weights that 
could be incurred. This is even truer for the vehicles considered in 
this petition, which, as discussed above, use a high proportion of 
advanced lightweight materials like carbon fiber reinforced plastics. 
That said, for purposes of this analysis, NHTSA believes that these 
weight values are reasonable to use to consider potential impacts on 
vehicle weight, as the agency does not now have updated weight 
estimates or estimates specifically for the specialized vehicle types 
considered in this proposed decision. Additionally, because of the 
lateness of the agency's response to these petitions, much of the 
projected weight difference may already be included on manufacturers' 
vehicles. It is possible that these values might overestimate any 
potential future weight impacts that may compete with manufacturers' 
ability to reduce weight to better achieve fuel economy improvements. 
The agency seeks comment on the methodology used, in addition to any 
specific information (including tear-down studies, etc.) that could 
better inform this analysis.
    Based on the agency's weight-versus-fuel-economy algorithms as 
applied in the 2012-2016 CAFE FRIA,\82\ a 3-4-pound increase in weight 
is projected to reduce fuel economy by 0.01 mpg. A manufacturer that 
had to comply with all additional FMVSS that NHTSA considered in the 
2017-2025 final rule would add 32.31 pounds to a passenger car in MY 
2025 versus a baseline 2008 passenger car, for an approximate fuel 
economy penalty of 0.09 mpg. Based on these estimates, NHTSA believes 
that it is reasonable to conclude that the small increase in weight 
from the FMVSSs would have negligible effects on any LVM fleet 
considered in this proposed decision.

    As to the impact that criteria pollutant emissions standards would 
have on a LVM's maximum feasible fuel economy level, EPA stated in its 
final rule establishing Tier 3 motor vehicle emissions and fuel 
standards that they ``do not expect the Tier 3 vehicle standards to 
result in any discernible changes in vehicle . . . fuel economy. 
Emissions of the pollutants that are controlled by the Tier 3 program--
NMOG, NOX, and PM--are not a function of the amount of fuel 
consumed, since manufacturers need to design their catalytic emission 
control systems to reduce these emissions regardless of their engine-
out levels.'' \83\ Moreover, EPA established special flexibility 
provisions for small businesses subject to the Tier 3 standards, which 
include small volume manufacturers (SVMs) that sell less than 5,000 
vehicles per year in the United States.\84\ In the Tier 3 final rule, 
EPA stated that the agency ``have found no fundamental reason why, 
given sufficient lead time, all manufacturers, regardless of company 
size and vehicle characteristics, will not be able to meet the Tier 3 
standards,'' but also established an optional alternative phase-in 
schedule for SVMs and non-SVM small businesses to meet the 
standards.\85\ Given these findings, NHTSA believes that it is 
reasonable to conclude that criteria pollutant emissions standards 
would have a negligible effect on any low volume

3. Proposed Maximum Feasible Average Fuel Economy for Exempted 
Manufacturers

    With these considerations taken together, NHTSA proposes to set 
alternative average fuel economy standards for these seven 
manufacturers for each model year at the following levels: NHTSA has 
received final fuel economy data from EPA for MYs 2008-2017 for all 
LVMs that have outstanding petitions for those years, and is proposing 
to use those final EPA values for those years. For MY 2018, NHTSA has 
some final EPA values for petitioning manufacturers' fleets, but not 
all; where NHTSA has a final EPA value for a manufacturer, NHTSA 
proposes to set the manufacturer's alternative standard at that level. 
Where NHTSA does not have a verified final EPA value for a 
manufacturer, NHTSA proposes to set the manufacturer's alternative 
standard at the level submitted by manufacturers in their non-final 
fuel economy reports to the agencies. NHTSA believes that all 
manufacturers covered by this proposed decision submitted information 
sufficient for the agency to conclude that their achieved fuel economy 
levels for past model years were the maximum feasible fuel economy 
levels that they could have achieved for those model years.
    For MYs 2019-2023, the proposed alternative standards take into 
consideration both CBI and non-CBI information submitted to the agency, 
including the manufacturer's requested alternative standard and 
predicted achieved fleet fuel economy value (if that value differed 
from the requested alternative standard). In addition, the alternative 
standards proposed today reflect NHTSA's belief that even though the 
manufacturers considered in this notice may have less capability to 
improve their fleet fuel economy than full-line manufacturers for the 
reasons listed above, manufacturers should aim to at least hold their 
fleet fuel economy constant, if not improve it year over year. Congress 
granted NHTSA the ability to provide an exemption to low volume 
manufacturers in part because it believed that the need of the nation 
would not be adversely affected by allowing the limited exemption; \86\ 
however, as discussed further in the draft environmental assessment 
below, transportation fuel consumption is expected to remain a major 
source of U.S. energy use through at least mid-decade. NHTSA believes 
that the proposed fuel economy levels presented below appropriately 
balance the CAFE exemption program with EPCA's directive to conserve 
energy, and that standards that do not backslide year over year for 
imminently future model years are therefore maximum feasible for the 
manufacturers petitioning the agency for alternative standards.
---------------------------------------------------------------------------

    \86\ See, e.g., 44 FR at 3711 (Jan. 18, 1979) (``The agency 
believes that the language in section 502(c) specifying that this 
agency may exempt low volume manufacturers indicates that Congress 
intended this agency to apply a test of whether granting an 
exemption would be generally consistent with the purposes of the 
Act. The main purpose of the Act is conserving energy.'').
---------------------------------------------------------------------------

    Considering the unique circumstances of this proposed decision, we 
also note that in accordance with 49 CFR 525.11--Termination of 
exemption; amendment of alternative average fuel economy standard, the 
agency may also initiate another rulemaking either on its own motion or 
on petition by an interested person to terminate an exemption granted 
under this part or to amend an alternative average fuel economy 
standard. While that may seem premature to mention at this point, as 
the agency has not yet issued final standards, NHTSA must set standards 
for a petitioning low volume manufacturer at the maximum feasible 
level. If additional data indicate that a manufacturer's achieved CAFE 
level differs significantly from the levels proposed in this notice or 
finalized, NHTSA will consider all options available to the agency to 
ensure that each manufacturer's alternative standard is the maximum 
feasible standard that the manufacturer can achieve. In addition, as 
discussed above, NHTSA will consider any additional information 
submitted by commenters, manufacturers (if additional information is 
available), or EPA (if additional final fuel economy data becomes 
available) that is submitted during the pendency of the comment period 
associated with this notice.
    Accordingly, NHTSA believes that the proposed alternative standards 
presented below are maximum feasible for these manufacturers for these 
model years, consistent with the purpose of EPCA/EISA.

    NHTSA seeks comment on the analysis that led to this proposed 
decision.

4. Regulatory Impact Analyses

a. Regulatory Evaluation

    NHTSA has considered the potential impacts of this action under 
Executive Order (E.O.) 12866 and the Department of Transportation's 
regulatory policies and procedures and has concluded that those orders 
do not apply, because this action is not an agency statement of general 
applicability and future affect. This decision is not generally 
applicable, because the agency has proposed to set alternative average 
fuel economy standards for each individual manufacturer.

b. Regulatory Flexibility Determination

    Pursuant to the Regulatory Flexibility Act (5 U.S.C. 601 et seq., 
as amended by the Small Business Regulatory Enforcement Fairness Act 
(SBREFA) of 1996), whenever an agency is required to publish a notice 
of proposed rulemaking, it must prepare and make available for public 
comment a regulatory flexibility analysis that describes the effect of 
the rule on small entities (i.e., small businesses, small 
organizations, and small governmental jurisdictions) unless the head of 
an agency certifies the proposal will not have a significant economic 
impact on a substantial number of small entities. The Small Business 
Administration's regulations at 13 CFR part 121 define a small 
business, in part, as a business entity ``which operates primarily 
within the United States.'' (13 CFR 121.105(a)). SBREFA amended the 
Regulatory Flexibility Act to require Federal agencies to provide a 
statement of the factual basis for certifying that a proposal will not 
have a significant economic impact on a substantial number of small 
entities.
    I certify this proposed decision would not have a significant 
impact on a substantial number of small entities. This proposed 
decision exempts low volume manufacturers from the generally applicable 
passenger car CAFE standards and proposes to set alternative standards 
for those low volume manufacturers at maximum feasible levels.

c. National Environmental Policy Act

    The National Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 
4321-4347) requires Federal agencies consider the environmental impacts 
of proposed major Federal actions significantly affecting the quality 
of the human environment, as well as the impacts of alternatives to the 
proposed action.\87\ The Council on Environmental Quality (CEQ) NEPA 
implementing regulations (40 CFR parts 1500-1508) direct Federal 
agencies to prepare an environmental assessment for a proposed action 
that is not likely to have significant effects or when the significance 
of the effects is unknown.\88\ The environmental assessment must 
``briefly discuss the purpose and need for the proposed action, 
alternatives[], and the environmental impacts of the proposed action 
and alternatives, and include a listing of agencies and persons 
consulted.'' \89\ This section serves as the National Highway Traffic 
Safety Administration's (NHTSA) Draft Environmental Assessment (Draft 
EA). NHTSA invites public comments on the contents and tentative 
conclusions of this Draft EA.

    \87\ 42 U.S.C. 4332(2)(C).
    \88\ 40 CFR 1501.5(a).
    \89\ 40 CFR 1501.5(c)(2).
---------------------------------------------------------------------------

1. Purpose and Need for Action
    In accordance with the Energy Policy and Conservation Act (EPCA) of 
1975, as amended by the Energy Independence and Security Act (EISA) of 
2007, and the procedures at 49 CFR part 525, the purpose of this 
proposal is to set alternative corporate average fuel economy (CAFE) 
standards for low volume manufacturers that have petitioned the agency 
for an alternative standard at the maximum feasible fuel economy level 
that NHTSA believes each manufacturer can achieve in each model year. 
While the purpose of setting industry-wide fuel economy standards under 
EPCA/EISA is, among other things, energy conservation, Congress granted 
NHTSA the ability to provide an exemption to low volume manufacturers 
in part because it believed that the need of the United States to 
conserve energy would not be adversely affected by allowing the limited 
exemption.\90\ If NHTSA did not grant alternative standards for low 
volume manufacturers, they would have to meet the industry-wide 
passenger car standard in each applicable model year, which, in most if 
not all cases, is more stringent than the maximum feasible fuel economy 
level that NHTSA believes these low volume manufacturers can achieve.
---------------------------------------------------------------------------

    \90\ See, e.g., 44 FR at 3711 (Jan. 18, 1979).
---------------------------------------------------------------------------

    When determining the maximum feasible fuel economy levels that 
manufacturers can achieve in each model year, EPCA/EISA requires that 
NHTSA consider four factors: technological feasibility, economic 
practicability, the effect of other motor vehicle standards of the 
government on fuel economy, and the need of the United States to 
conserve energy. NHTSA relies on information in each low volume 
manufacturer's petition for exemption, which are discussed in more 
detail in the preamble above, to propose alternative average fuel 
economy standards at the maximum feasible level for each manufacturer. 
However, the unique nature of this action requires NHTSA to set maximum 
feasible standards for model years that have already passed. NHTSA's 
proposed action and range of alternatives considered below reflects 
these statutory and practical considerations.
2. Proposed Action and Alternatives
    For this action NHTSA has considered a No Action Alternative and 
two alternatives. The No Action Alternative assumes that in the absence 
of NHTSA action on their petitions, manufacturers would meet their 
footprint-based CAFE standard for MYs 2013-2023.\91\ One action 
alternative proposes to set alternative standards at the levels that 
the manufacturers requested for model years that NHTSA does not have 
final fuel economy data (the ``as-requested'' alternative); and the 
preferred alternative proposes to set standards at the levels detailed 
in the preamble above. NHTSA did not consider an alternative that 
proposed to set an alternative standard for a model year at a lower 
level than the manufacturer achieved in past model years (i.e., in some 
cases for past model years what the manufacturer requested) because 
that would not have been the maximum feasible fuel economy level that 
the manufacturer could have achieved.
---------------------------------------------------------------------------

    \91\ As discussed above, NHTSA has expired MY 2012 and earlier 
fuel economy credits in accordance with 49 CFR 536.5(c)(2), meaning 
that low volume manufacturers that built vehicles in MYs 2008-2012 
cannot now buy fuel economy credits from manufacturers that exceeded 
their CAFE standard in those years to offset the CAFE values of the 
low volume vehicles produced in those years. As a simplifying 
assumption, because there can be no difference between the fuel used 
in MYs 2008-2012 under the No Action Alternative baseline and action 
scenarios, fuel use in those years was not considered.

---------------------------------------------------------------------------

[[Page 39455]]

3. Affected Environment
    Broadly, NHTSA actions regulating motor vehicle fuel economy could 
have a range of environmental impacts, including to energy use, air 
quality, climate change, resource extraction and use, and to 
environmental justice communities, among others. Every time NHTSA sets 
industry-wide CAFE standards, the agency examines the environmental 
impact of the proposed standards and a range of alternatives on these 
resources in an environmental impact statement (EIS). The EIS uses 
estimates of fuel consumption that would result if the agency adopted 
different levels of fuel economy standards to quantitatively estimate 
the impacts to energy use, air quality, and greenhouse gas emissions 
and climate change. NHTSA also qualitatively discusses the lesser 
impacts to other resource areas, including land use and development, 
hazardous materials and regulated waste, historical and cultural 
resources, noise, and environmental justice. NHTSA's recent Final 
Supplemental Environmental Impact Statement (Final SEIS) for the notice 
of proposed rulemaking (NPRM) for MY 2024-2026 passenger car and light 
truck fuel economy standards (hereinafter ``Final SEIS'') provides the 
most up-to-date estimates of the impact of different levels of fuel 
economy standards on these resource areas and discussion of the 
environmental impacts. The Final SEIS discussions of environmental 
impacts resulting from changes in fuel use from motor vehicles is 
incorporated by reference here,\92\ as discussed further below.
---------------------------------------------------------------------------

    \92\ 40 CFR 1501.12.
---------------------------------------------------------------------------

    Transportation fuel accounts for a large portion of total U.S. 
energy consumption and energy imports and has a significant impact on 
the functioning of the energy sector as a whole. Although U.S. energy 
efficiency has been increasing and the U.S. share of global energy 
consumption has been declining in recent decades, total U.S. energy 
consumption has been increasing over that same period. Until a decade 
ago, most of this increase came not from increased domestic energy 
production but from the increase in imports, largely for use in the 
transportation sector. U.S. net petroleum imports are expected to 
result primarily from fuel consumption by light-duty and heavy-duty 
vehicles, with the transportation sector expected to account for 76.9 
percent of total U.S. petroleum consumption by 2050. This means that 
the transportation sector will continue to be the largest consumer of 
U.S. petroleum and the second-largest consumer of total U.S. energy, 
after the industrial sector. Please refer to Chapter 3 of the Final 
SEIS (Energy) for a comprehensive discussion of transportation sector 
energy impacts, including discussions of how the passenger car and 
light truck vehicle sector affects overall energy use in the United 
States and how improvements in the fuel economy of vehicles and 
increasing energy production together affect U.S. energy security by 
reducing the overall U.S. trade deficit and the macroeconomic 
vulnerability of the United States to foreign oil supply disruptions.
    Next, several human activities related to motor vehicles cause 
gases and particles to be emitted into the atmosphere, including 
driving cars and trucks; extracting, refining, and transporting crude 
oil; burning coal, natural gas, and other fossil fuels; and 
manufacturing chemicals and other products from raw materials as well 
as other industrial and agricultural operations. Emissions of vehicle-
related sources of air pollutants, including criteria pollutants and 
mobile source air toxics (MSATs), from both upstream fuel extraction 
processes and vehicle tailpipes impact air quality.\93\ In addition to 
causing adverse environmental impacts, air pollution from upstream and 
downstream sources causes emissions-related health conditions like 
increased asthma incidences, work-loss days, and even premature 
mortality.
---------------------------------------------------------------------------

    \93\ In the motor vehicle context, emissions from fuel 
extraction, refining, and transportation are generally referred to 
as upstream emissions, while emissions from the tailpipe of the 
vehicle that result from the vehicle being driven are generally 
referred to as downstream emissions. Decreases in upstream emissions 
could result from decreases in gasoline consumption, and therefore 
lower volumes of fuel production and distribution, while decreases 
in downstream emissions generally occur because of on-vehicle 
pollution controls like catalytic converter systems or because the 
vehicle is being driven less, and therefore emits fewer emissions 
from the tailpipe.
---------------------------------------------------------------------------

    To reduce air pollution levels, the Environmental Protection Agency 
(EPA) (and some state agencies, like the California Air Resources 
Board) established regulatory programs to control sources of emissions 
from transportation. The regulatory programs that cover the vehicles 
subject to proposed alternative CAFE standards in this notice include 
EPA's Tier 2 and Tier 3 vehicle emissions and gasoline standards, which 
prescribe reductions in vehicle tailpipe emissions as well as limits 
for the sulfur content in gasoline. As discussed further in Chapter 4 
of NHTSA's Final SEIS (Air Quality), since the 1970s aggregate 
emissions traditionally associated with vehicles have decreased 
substantially even as vehicle miles traveled (VMT) increased by 
approximately 173 percent from 1970 to 2014, and additional growth in 
VMT will have a smaller impact on emissions because of these stricter 
EPA standards for vehicle tailpipe emissions and fuels.\94\
---------------------------------------------------------------------------

    \94\ Final SEIS, at 4-13.
---------------------------------------------------------------------------

    Chapter 4 of the Final SEIS also discusses how air pollutant 
emissions increase the risk of adverse health impacts, particularly for 
populations that live, work, or go to school near high-traffic roadways 
or that are exposed to high-traffic; the human health and environmental 
effects of criteria pollutants and MSATs; the relevant regulatory 
programs that control air pollutant emissions from vehicles and 
gasoline; and trends in travel and emissions from highway vehicles. 
Chapter 4 estimates the impact of emissions of criteria pollutants and 
MSATs from passenger cars and light trucks that would result from 
different levels of increases in CAFE standards for the U.S. light duty 
vehicle fleet. Please refer to that Chapter for a comprehensive 
discussion of those impacts.
    Finally, as discussed further in Chapter 5 of the Final SEIS 
(Greenhouse Gas Emissions and Climate Change), the carbon dioxide and 
other greenhouse gasses emitted from the tailpipes of vehicles driven 
in the United States have global impacts. Chapter 5 of the Final SEIS 
provides a comprehensive survey of panel-reviewed synthesis and 
assessment reports from the Intergovernmental Panel on Climate Change 
(IPCC) and U.S. Global Climate Change Research Program (GCRP), 
supplemented with past reports from the U.S. Climate Change Science 
Program (CCSP), the National Research Council, the Arctic Council, and 
EPA's Technical Support Document for Endangerment and Cause or 
Contribute Findings for Greenhouse Gases under the Clean Air Act (EPA 
2009), which relied heavily on past major international or national 
scientific assessment reports, to provide decisionmakers and the public 
with information about climate change's potential impacts on health, 
society, and the environment. Increases in greenhouse gas emissions, in 
particular from human activities like burning fossil fuels,\95\ leads 
to changes in global

[[Page 39456]]

average surface temperature, precipitation, ice cover, sea level, cloud 
cover, sea surface temperatures and currents, and other climate 
conditions.
---------------------------------------------------------------------------

    \95\ While greenhouse gas emissions and the corresponding 
processes that affect the aforementioned climate parameters are 
highly complex and variable, an increasing number of studies 
conclude that anthropogenic greenhouse gas emissions are affecting 
the global climate in detectable and quantifiable ways.
---------------------------------------------------------------------------

    Chapter 5 of the Final SEIS explains how NHTSA estimated the levels 
of greenhouse gas emissions that would result from different levels of 
CAFE standards, and how the agency modeled certain climate parameters 
including global concentrations of CO2, sea level rise, 
global mean surface temperature, and ocean pH. At the levels of 
estimated fuel use resulting from different levels of industry-wide 
CAFE standards for model years 2024-2026, NHTSA estimated the following 
global impacts (presented as a range between the no action alternative, 
which is an approximately 1.5 percent year over year increase in the 
industry-wide light duty CAFE standards, and the most stringent action 
alternative, which is an approximately 10 percent year over year 
increase in the industry-wide light duty CAFE standards).\96\

--------------------------------------------------------------------------------------------------------------------------------------------------------

    Although actions related to motor vehicle fuel economy have local, 
national, and global effect, it is difficult to assess the area of 
effect for this action because--unlike the industry-wide EIS that 
assigns nationwide impacts based in part on population \97\--NHTSA does 
not know where the vehicles considered in this action are sold and 
driven. Therefore, as discussed further below, NHTSA made several 
simplifying assumptions for purposes of estimating the environmental 
impacts of the proposed action and alternatives.
---------------------------------------------------------------------------

    \97\ Moreover, this is unlike a typical NEPA action such as a 
pipeline route, forest management plan, etc. that considers a site-
specific proposal and site-specific alternatives.
---------------------------------------------------------------------------

    The following subsection presents the estimated impacts of this 
action on fuel use for each alternative and the associated estimated 
downstream greenhouse gas emissions impacts based on estimated fuel 
use. NHTSA did not conduct independent climate or air quality modeling 
for this action because, as discussed further below, the agency 
believes that it is reasonable to infer from the amount of estimated 
fuel used under each alternative that none of the alternatives 
considered in this notice would result in appreciable environmental 
impacts, and this information would not result in any new meaningful 
information for decisionmakers and the public. To read a comprehensive 
discussion of the resource areas summarized above, or the other 
resource areas considered when setting industry-wide CAFE standards, 
please see the Final SEIS.
4. Environmental Consequences
    Like the estimates of fuel consumption that would result if NHTSA 
set industry-wide CAFE standards at different levels, NHTSA's fuel 
consumption estimates calculated for this action provide a starting 
point to estimate a relative potential range of environmental impacts.
    To estimate the amount of additional fuel consumed by the exempted 
fleet over its operating lifetime,\98\ NHTSA calculated the difference 
between the low volume manufacturer's footprint-based standard for MY 
2013 forward (i.e., the estimated fuel used under the no-action 
alternative, for model years for which fuel economy credits are 
available) and their proposed alternative standard (or achieved fleet 
fuel economy for model years that have already passed). NHTSA 
multiplied this difference by the manufacturer's estimated U.S. 
production volume,\99\ and then by an estimated total miles that these 
vehicles could travel as an active part of the fleet (i.e., the 
vehicles' estimated yearly VMT).\100\ The resulting estimates of 
additional lifetime fuel consumption for all manufacturers and model 
years considered in this action compared to the no-action alternative 
are shown below.
---------------------------------------------------------------------------

    \98\ Approximately 15 years, based on the estimated passenger 
sedan life as calculated in the latest industry-wide CAFE rulemaking 
action.
    \99\ As discussed in the preamble, where NHTSA did not have 
final production data for a manufacturer, in particular where 
estimated production data is still confidential, the agency averaged 
the last three years of a manufacturers' actual production data.
    \100\ As discussed in the preamble, NHTSA estimated that a high-
performance vehicle would travel 2,543 miles per year, while a 
mobility van would travel 11,128 miles per year.

                                                                                     Preferred
                                                                     No action      alternative    As requested

Total Gallons...................................................      48,873,908      88,643,357      88,997,267
Difference from the No Action Alternative.......................  ..............      39,769,449      40,123,359
----------------------------------------------------------------------------------------------------------------

    To put this in perspective, NHTSA looked at the average amount of 
fuel consumed by an average passenger car subject to the industry-wide 
passenger car CAFE standard over its useful life, in this case a MY 
2017 Toyota Camry. The estimated total gallons of fuel used if 
standards are set at the levels proposed in this action are roughly 
equivalent to the fuel used by approximately 8,534 MY 2017 Toyota 
Camrys. In other words, setting alternative standards at the levels 
proposed in this notice for the 15 model years covered by this notice 
would have the energy effect of a one-time addition of 171 MY 2017 
Toyota Camrys per U.S. state. Compared to the pre-pandemic peak of 
approximately 17 million vehicles sold in the United States in a model 
year, the vehicles considered in

[[Page 39457]]

this notice that cover fifteen model years contribute only a small 
amount to total U.S. transportation fuel use.
    As with the impacts to energy use, NHTSA expects that the proposed 
action would have a relatively minimal impact on air quality, and 
accordingly, air quality related health effects, based on the relative 
percentage of fuel used by the vehicles considered in this action 
compared to total light-duty vehicle fuel use. As discussed in Chapter 
4 of NHTSA's Final SEIS, nationwide criteria pollutant emissions from 
vehicle tailpipes are projected to decrease over time, even as VMT 
increases, due to increasingly stringent EPA regulation of criteria 
pollutant emissions and reductions in emissions from fuel production. 
NHTSA does not expect that trend to change based on the levels of fuel 
use projected for this action. In addition, some of the increases in 
criteria pollutant emissions projected in the Final SEIS are due to 
increases in upstream emissions from power plants from increased 
electric vehicle use. The vehicles considered in this action run 
primarily on gasoline; none of the vehicles with electrified 
powertrains draw energy from the electric grid. The same projected 
trends exist for toxic air pollutants; emissions are projected to 
decrease through 2050 based on increasingly stringent EPA regulations 
and reductions in emissions from fuel production, despite growth in 
total VMT. NHTSA does not expect that any of these trends would change 
based on the minor increases in fuel use projected from this action.
    To estimate the approximate effect that this action would have on 
greenhouse gas emissions, NHTSA first used EPA's Greenhouse Gas 
Equivalencies Calculator to convert the estimated additional gallons of 
gasoline that would be used under the alternatives to metric tons of 
carbon dioxide equivalent emissions.\101\ Over the lifetime of all 
model year vehicles considered in this notice (15 model years' worth of 
vehicles that each last approximately 15 years), for the fuel use 
considered in this action, the following additional carbon dioxide 
equivalent emissions are expected to result: 285,193 metric tons of 
carbon dioxide equivalent emissions under the ``as-requested'' 
alternative, and 282,047 metric tons of carbon dioxide equivalent 
emissions at the preferred alternative levels. To put this in 
perspective, NHTSA referenced EPA's Inventory of U.S. Greenhouse Gas 
Emissions and Sinks 1990-2019 report, which estimated that the U.S. 
passenger car and light truck vehicle fleet emits a little over a 
thousand million metric tons of carbon dioxide equivalent emissions per 
year (averaged over 2017, 2018, and 2019).\102\ Over the useful life of 
a vehicle considered in this action, the vehicles considered in this 
action are estimated to produce an estimated increase in carbon dioxide 
equivalent emissions of 0.00169% and 0.00167% (for the as-requested and 
preferred alternative levels, respectively) of total light duty vehicle 
carbon dioxide equivalent emissions over what the vehicles would have 
produced had they met their footprint-based standard.
---------------------------------------------------------------------------

    \101\ U.S. EPA Greenhouse Gas Equivalencies Calculator, https://www.epa.gov/energy/greenhouse-gas-equivalencies-calculator. EPA 
specifies that estimates from this calculator are approximate and 
should not be used for emission inventories or formal carbon 
emissions analysis. NHTSA used these estimates as part of its 
determination that a formal carbon emissions analysis is not 
required for this action.
    \102\ U.S. EPA, Inventory of U.S. Greenhouse Gas Emissions and 
Sinks: 1990-2019, at Table 2-13, available at https://www.epa.gov/sites/default/files/2021-04/documents/us-ghg-inventory-2021-main-text.pdf?VersionId=wEy8wQuGrWS8Ef_hSLXHy1kYwKs4.ZaU.
---------------------------------------------------------------------------

    NHTSA did not perform independent climate modeling for this 
proposal because the agency believes that is reasonable to infer that 
if relatively small--but not trivial--climate impacts would result from 
large-scale changes in fuel use from changes in the industry-wide 
passenger car and light truck standards, as shown in the table of 
estimated atmospheric CO2 concentrations, global mean 
surface temperature increases, sea-level rise, and ocean pH above, 
estimating the impacts of the no action alternative and alternatives 
presented in this notice would not present any additional meaningful 
information for decisionmakers and the public.
    Some potential impacts of the proposed action could be mitigated 
through other means; as discussed above, EPA also sets alternative 
carbon dioxide emissions standards for some of the low volume 
manufacturers considered in this notice. Unlike the structure of EPCA/
EISA, which allows civil penalty payment for each 0.1 of a mile a 
gallon by which the manufacturer falls short of the applicable average 
fuel economy standard,\103\ manufacturers must be in compliance with 
EPA regulations promulgated under the Clean Air Act to sell their 
vehicles. To the extent that EPA sets higher alternative standards for 
model year 2022 and 2023 vehicles, some of the estimated impacts could 
be mitigated. Next, the estimates of fuel use presented here are 
dependent on several assumptions, one being how many miles these 
vehicles are driven. The vehicles covered by this proposed exemption 
represent an extremely small fraction of overall motor vehicle sales 
and on-road VMT; most of the vehicles considered in this notice are 
estimated to drive a quarter of the mileage of the average passenger 
car. If these vehicles were or are driven less than NHTSA estimated, 
fuel use, air quality impacts, and greenhouse gas emissions would be 
reduced accordingly. However, to the extent that some of the vehicles 
considered in this action have already been built and sold, the impacts 
of those vehicles achieving a lower fuel economy level than their 
footprint-based standard represent an unavoidable adverse impact.

    Both alternatives considered in this Draft EA result in increased 
fuel use compared to the no-action alternative; however, the preferred 
alternative does result in marginally less estimated fuel use than the 
``as requested'' alternative. NHTSA does not believe that establishing 
alternative CAFE standards at the preferred alternative levels would 
contribute appreciably to any of the environmental impacts considered 
in this Draft EA. NHTSA seeks comment on this analysis and whether 
there are any environmental impacts that the agency has not considered 
that are relevant to a reasoned choice by the decisionmaker.
5. Agencies and Persons Consulted
    NHTSA coordinated with EPA to seek their feedback on this Draft EA, 
and EPA had no comments or suggested changes.
6. Conclusion
    NHTSA has reviewed the information presented in this Draft EA and 
concludes that the proposed action would have minimal impacts on the 
quality of the human environment. Based on the information in this 
Draft EA and assuming no additional information or changed 
circumstances, NHTSA expects to issue a Finding of No Significant 
Impact (FONSI). Such a finding will be made only after careful review 
of all public comments received. A Final EA and a FONSI, if 
appropriate, will be issued as part of the final rule.
