NHTSA Proposes Increases In Fuel Economy Standards


The National Highway Traffic Safety Administration has released a proposed rule to increase 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 (with gross vehicle weight ratings of more than 8,500 pounds up to 14,000 pounds) for model years 2030-2035.

The proposed rule would raise fuel economy standards for passenger cars and light trucks and fuel efficiency standards for model years (MYs) 2027-31 by 2% per year for passenger cars and 4% 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% per year.

NHTSA is also proposing standards for MY 2032 passenger cars and light trucks, that would increase at 2% and 4% 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 in MY 2032 and an industry fleet-wide average for HDPUVs of roughly 2.6 gallons per 100 miles in MY 2038.

Vehicle manufacturers supposedly can meet the requirements with a mix of electric vehicles, gasoline-electric hybrids and efficiency improvements in gasoline and diesel vehicles.

NHTSA says its proposed fuel economy standards complement and align with the Environmental Protection Agency’s recently proposed greenhouse gas emissions standards for similar vehicle fleets, although each agency has its own authority to regulate in this area.
