The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule III for Model Years 2022 to 2031 Passenger Cars and Light Trucks
The National Highway Traffic Safety Administration (NHTSA), on behalf of the U.S. Department of Transportation (DOT), is substantially recalibrating the Corporate Average Fuel Economy (CAFE) program to bring the program into compliance with the law and to remove previous regulatory distortions which have induced manufacturers to make design decisions that have neither aligned with market demand and the needs of American families nor have delivered the consistent improvements in the fuel economy performance of manufacturer fleets, as Congress intended. This recalibration finalizes amendments to fuel economy standards for light-duty vehicles for model years 2022-2026 and MYs 2027-2031. This final rule also finalizes amendments to compliance aspects of the program, including to vehicle classification and other compliance pathways. This rule is effective 30 November 2026. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of 30 November 2026. 91 Federal Register (FR) 61988, 30 September 2026; Title 49 Code of Federal Regulations (CFR) Parts 523, 531, 533, 536, and 537: This final rule and previous actions notified under the symbol G/TBT/N/USA/2253 are identified by Docket Number NHTSA-2025-0491.

Notice of proposed rulemaking - The National Highway Traffic Safety Administration (NHTSA), on behalf of the Department of Transportation (DOT), proposes to substantially recalibrate the Corporate Average Fuel Economy (CAFE) program to realign this program with Congressional intent. That recalibration includes proposing to amend DOT's fuel economy standards for light-duty vehicles for model years (MYs) 2022- 2026 and MYs 2027-2031. Consistent with statutory requirements, the fuel economy standards proposed in this rule are founded on light-duty vehicles powered by gasoline and diesel fuels, a category that includes non-plug-in hybrid vehicles. In formulating the proposed standards, NHTSA has not considered, consistent with law, the imputed fuel-economy performance of battery-powered electric vehicles (EVs) or the electric operation of vehicles that use plug-in hybrid electric powertrains, nor compliance credits or adjustments to the two-cycle fuel economy test procedures to account for air conditioning and off-cycle technologies. NHTSA also is proposing to eliminate the inter-manufacturer credit trading system and to amend the light-duty vehicle fleet classification system to allocate vehicles into passenger and non-passenger automobile fleets appropriately, based on their attributes and capabilities, starting in MY 2028. Elimination of unlawful considerations, combined with several of the proposed changes, would significantly improve the capabilities of manufacturers to…
