Average Fuel Economy Standards for Light Trucks Model Years 2008-
2011

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

[[Page 19450]]


ACTION: Final rule; correction.

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

SUMMARY: The National Highway Traffic Safety Administration published 
in the Federal Register of April 6, 2006, a final rule establishing 
Corporate Average Fuel Economy (CAFE) standards for light trucks 
manufactured in model years 2008 through 2011. Inadvertently, the 
document had the wrong docket number; footprint and target fuel economy 
values provided in example calculations did not have the correct number 
of decimal places; the definition of ``footprint'' in the regulatory 
text was incorrect; and Figure 1 of the regulatory text incorrectly 
referenced ``model,'' as opposed to ``model type.'' Additionally, there 
was a typographical error in the regulatory text regarding the flat 
floor provision. This document makes the appropriate corrections.

Effective Date: August 4, 2006. Petitions for reconsideration must be 
received by May 22, 2006.

FOR FURTHER INFORMATION CONTACT: For technical issues, call Ken Katz, 
Lead Engineer, Fuel Economy Division, Office of International Vehicle, 
Fuel Economy, and Consumer Standards, at (202) 366-0846, facsimile 
(202) 493-2290, electronic mail [email protected]. For legal issues, 
call Stephen Wood or Christopher Calamita of the Office of the Chief 
Counsel, at (202) 366-2992, or e-mail them at [email protected] or

SUPPLEMENTARY INFORMATION: The National Highway Traffic Safety 
Administration published in the Federal Register of April 6, 2006, (71 
FR 17566) a final rule establishing fuel Corporate Average Fuel Economy 
(CAFE) standards for light trucks manufactured in model years 2008 
through 2011. Inadvertently, the document had the wrong docket number; 
footprint and target fuel economy values provided in example 
calculations did not have the correct number of decimal places; the 
regulatory text incorrectly incorporated the proposed definition of 
``footprint,'' as opposed to the final definition discussed in the 
preamble of the final rule; and Figure 1 of the regulatory text 
incorrectly referenced ``model'' instead of ``model type.''
    This document provides the correct docket number, amends the 
footprint values in example calculations such that the footprint values 
are provided to the nearest tenth of a square foot, amends the fuel 
economy target values in example calculations such that the target 
values are provided to the nearest hundredth mile per gallon, amends 
the definition of ``footprint'' to clarify the precision of the value 
and reflect the definition discussed in the preamble, and amends Figure 
1 by referencing ``model type.'' Additionally, this document corrects a 
typographical error in the ``flat floor'' regulatory text, i.e., 
``flat-leveled cargo surface'' is corrected to read ``flat, leveled 
cargo surface.''
    In FR Docket No. NHTSA 2006-24306 published on April 6, 2006 (71 FR 
17566) make the following corrections.
    On page 17566, in the first column, the Docket number is revised to 
read, ``NHTSA No. 2006-24309.''
    On page 17608, Table 5 is revised to read as follows,

    On page 17609, at the top of the page, the formula labeled 
``Required CAFE Level'' is revised to read as follows,

    On page 17676, in the first column, the definition of 
``Footprint,'' is revised to read, ``Footprint is defined as the 
product of track width (measured in inches and rounded to the nearest 
tenth of an inch) times wheelbase (measured in inches and rounded to 
the nearest tenth of an inch) divided by 144 and then rounded to the 
nearest tenth of a square foot. For purposes of this definition, track 
width is the lateral distance between the centerlines of the base tires 
at ground, including the camber angle. For purposes of this definition, 
wheelbase is the longitudinal distance between front and rear wheel 
centerlines.''
    On page 17676, in the third column, paragraph (ii) is revised to 
read, ``For light trucks manufactured in model year 2008 and beyond, 
for vehicles equipped with at least 3 rows of designated seating 
positions as standard equipment, permit expanded use of the automobile 
for cargo-carrying purposes or other nonpassenger-carrying purposes 
through the removal or stowing of foldable or pivoting seats so as to 
create a flat, leveled cargo surface extending from the forwardmost 
point of installation of those seats to the rear of the automobile's 
interior.''
    On the bottom of page 17676 and continuing on the top of page 
17677, between Table IV and V, Figure 1 is revised to read as follows,

[[Page 19451]]

Where:

N is the total number (sum) of light trucks produced by a manufacturer, 
Ni is the number (sum) of the ith light truck 
model type produced by the manufacturer, and
Ti is fuel economy target of the ith light truck 
model type, which is determined according to the following formula, 
rounded to the nearest hundredth:

    Note to Appendix A Table 1. Manufacturer X's required corporate 
average fuel economy level under Sec.  533.5(g) would be calculated 
by first determining the fuel economy target applicable to each 
vehicle as illustrated in ``Appendix A Figure 1:''

to read as follows:

    Note to Appendix A Figure 1. Accordingly, vehicle models A, B, 
C, D, E, and F would be compared to fuel economy values of 26.20, 
25.50, 24.80, 23.30, 21.70, and 20.30 mpg, respectively. With the 
appropriate fuel economy targets calculated, Manufacturer X's 
required fuel economy would be calculated as illustrated in 
``Appendix A Figure 2.''
