Corporate Average Fuel Economy Standards for Passenger Cars and Light Trucks for Model Years 2027-2032 and Fuel Efficiency Standards for Heavy-Duty Pickup Trucks and Vans for Model Years 2030-2035; (263 page(s), in English)
Notice of proposed rulemaking - NHTSA, on behalf of the Department of Transportation (DOT), is proposing new fuel economy standards for passenger cars and light trucks and fuel efficiency standards for model years (MYs) 2027–31 that increase at a rate of 2 percent per year for passenger cars and 4 percent per year for light trucks, and new fuel efficiency standards for heavy-duty pickup trucks and vans (HDPUVs) for MYs 2030–2035 that increase at a rate of 10 percent per year. NHTSA is also setting forth proposed augural standards for MY 2032 passenger cars and light trucks, that would increase at 2 percent and 4 percent year over year, respectively, as compared to the prior year's standards. NHTSA currently projects that the proposed standards would require an industry fleet-wide average for passenger cars and light trucks of roughly 58 miles per gallon (mpg) in MY 2032 and an industry fleet-wide average for HDPUVs of roughly 2.6 gallons per 100 miles in MY 2038. NHTSA further projects that the proposed standards would reduce average fuel outlays over the lifetimes of passenger cars and light trucks by $1,043 and of HDPUVs by $439. These proposed standards are directly responsive to the agency's statutory mandate to improve energy conservation and reduce the nation's energy dependence on foreign sources.
