New Vehicles Must Average 40 mpg by 2026, up From 28 mpg

DETROIT (AP) — New vehicles sold in the U.S. will have to travel an average of at least 40 miles per gallon of gasoline in 2026 under new rules unveiled by the government.

The National Highway Traffic Safety Administration said Friday its fuel economy requirements will undo a rollback enacted under President Donald Trump.

The new requirements increase gas mileage by 8% per year for model years 2024 and 2025 and 10% in the 2026 model year.

For the current model year, standards enacted under Trump require the fleet of new vehicles to get just over 28 miles per gallon in real-world driving.

Some environmental groups say the new standards aren’t tough enough.
