Corporate Average Fuel Economy Standards for Passenger Cars and Light Trucks for Model Years 2027 and Beyond (CAFE) and Fuel Efficiency Standards for Heavy-Duty Pickup Trucks and Vans for Model Years 2030 and Beyond

This rule by the National Highway Traffic Safety Administration (NHTSA) establishes Corporate Average Fuel Economy (CAFE) standards for passenger cars and light trucks that increase at a rate of 2 percent per year for passenger cars in model years (MYs) 2027-31, 0 percent per year for light trucks in model years 2027-28, and 2 percent per year for light trucks in model years 2029-31. NHTSA is also finalizing fuel efficiency standards for heavy-duty pickup trucks and vans (HDPUVs) for model years 2030-32 that increase at a rate of 10 percent per year and model years 2033-35 that increase at a rate of 8 percent per year.

In January 2025, the NHTSA secretary sent a memorandum to NHTSA to review and reconsider this policy, per Trump's executive orders.
