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

ACTION: Notification of public hearing.

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

SUMMARY: The National Highway Traffic Safety Administration (NHTSA) is 
announcing a virtual public hearing to be held January 7, 2026 on its 
proposal for the ``The Safer Affordable Fuel-Efficient (SAFE) Vehicle 
Rule III for Model Years 2022 to 2031 Passenger Cars and Light 
Trucks,'' which was signed on December 2, 2025. This hearing also 
allows the public to provide oral comments regarding the Draft 
Supplemental Environmental Impact Statement (Draft SEIS) that 
accompanies the proposal. An additional virtual session will be held on 
January 8, 2026, if necessary, to accommodate the number of people that 
sign up to speak.

DATES: NHTSA will hold a virtual public hearing on January 7, 2026. An 
additional session will be held on January 8, 2026, if necessary, to 
accommodate the number of people that sign up to testify. Please refer 
to the SUPPLEMENTARY INFORMATION section for additional information on 
the public hearing.

ADDRESSES: The virtual public hearing will be held on January 7, 2026. 
An additional session will be held on January 8, 2026, if necessary, to 
accommodate the number of speakers that sign up to testify. Each day 
the hearing will convene at 9:00 a.m. Eastern Time and will conclude 
when the last pre-registered speaker has testified but no later than 
6:00 p.m. Eastern Time. All hearing attendees, including those who do 
not intend to provide oral testimony, should register by December 31, 
2025. The link to register will be available at http://www.nhtsa.gov/cafe. Additional information regarding the hearing appears below under 
SUPPLEMENTARY INFORMATION.

FOR FURTHER INFORMATION CONTACT: For questions regarding how to 
register to attend the hearing, please contact NHTSA's Office of 
Communications at [email protected]. For any other questions 
about this notice, please contact Joseph Bayer, Corporate Average Fuel 
Economy (CAFE) Program Division Chief, Office of Rulemaking, NHTSA, at 
[email protected].

SUPPLEMENTARY INFORMATION: NHTSA, on behalf of the Department of 
Transportation, is proposing to amend CAFE standards for light-duty 
vehicles for model years (MYs) 2022-2026 and MYs 2027-2031. Consistent 
with the requirements of the CAFE program, the fuel economy standards 
proposed in this rule are founded on light-duty vehicles powered by 
gasoline and diesel fuels, a category that these rules treat as 
including non-plug-in hybrid vehicles. In formulating the proposed 
standards, NHTSA has not considered the imputed fuel-economy 
performance of battery-powered electric vehicles or the electric 
operation of vehicles that use plug-in hybrid electric powertrains and 
has not considered compliance credits nor adjustments to the 
statutorily required two-cycle fuel economy test procedures to account 
for air conditioning and off-cycle technologies, since such 
consideration is prohibited by statute. NHTSA is proposing to set fuel 
economy standards that increase from the newly proposed MY 2022 
standards at 0.5 percent per year through MY 2026 followed by 0.25 
percent per year through MY 2031, with MY 2027 stringency as a bridge 
between the two sets of standards. The reduced stringency in later 
years, coupled with a reevaluation of the coefficients that define the 
fuel economy standards functions, are intended to enable the industry 
to adapt to proposals to remove credit trading and to classify 
passenger and non-passenger automobiles appropriately, based on their 
attributes and capabilities, starting in MY 2028. NHTSA projects that 
the amended standards would correspond to industry fleetwide average 
all light-duty vehicles of roughly 34.5 miles per gallon (mpg) in MY 
2031. The proposal was signed on December 2, 2025, and was published in 
the Federal Register on December 5, 2025 (90 FR 56438). A notice of 
availability for the accompanying Draft SEIS was published in the 
Federal Register on December 5, 2025 (90 FR 56144). The Draft SEIS is 
available on NHTSA's CAFE website, https://www.nhtsa.gov/cafe, and is 
also available in Docket ID No. NHTSA-2025-0490.
