The Trump administration is preparing to ease federal fuel economy rules for cars and trucks, undoing stricter requirements adopted under former President Joe Biden.

Transportation Secretary Sean Duffy said that the administration would soon release the new standards. The move reverses policies that increased efficiency mandates on vehicle manufacturers during the previous administration.

Industry observers have long argued that the Biden-era rules imposed significant compliance costs on automakers and limited consumer choice in the vehicle market. The expected changes aim to provide greater flexibility for manufacturers while maintaining safety and environmental standards.

Duffy's remarks came as the administration continues to review a range of regulatory actions from the prior term. Officials have indicated the new fuel economy framework will prioritize practical outcomes over aggressive targets.

The announcement follows similar efforts by the administration to streamline other federal regulations affecting the transportation sector. Details on the precise changes to the Corporate Average Fuel Economy standards are anticipated in the coming weeks.
