NHTSA proposes cutting fuel use almost in half by 2035

Washington — The Biden administration plans to cut vehicle fuel consumption almost in half by 2035, according to new proposed Corporate Average Fuel Economy standards released Friday by the U.S. Department of Transportation’s National Highway Traffic Safety Administration.

The rules would once again increase fuel efficiency, pushing car companies to meet an estimated 58 mile per gallon average fuel economy by model year 2032. It would require automakers to improve fuel efficiency by 2% every year for cars and 4% per year for light trucks beginning in model year 2027.

The proposed standards also would increase fuel economy standards for heavy duty pickup trucks and work vans by 10% annually model years 2030 to 2035. Combined, NHTSA estimates that the country’s total fleet fuel consumption would be cut by 48% by model year 2035. 

Comparatively, a 2022 rulemaking bumped up the existing standard to 49 miles per gallon fleetwide by model year 2026, with 8% efficiency increases in model years 2024 and 2025 and a 10% increase in model year 2026.

For model year 2023, passenger cars must get 50.5 miles to the gallon and light duty trucks must get 35.8 miles to the gallon.

The agency can’t consider electric vehicles or alternative fuels in determining whether automakers can feasibly comply with the rules, but car companies can use EVs to meet the requirements — meaning regulators believe car companies could meet the requirements even if they were not pivoting to EVs. NHTSA estimates the proposed standards would result in an estimated 56% EV market penetration by 2032, Acting Administrator Ann Carlson said Friday.

“These targets are consistent with Congress’ direction to conserve fuel and promote American energy independence and American auto manufacturing,” Carlson said.
