A key lobby group for automakers in the United States has failed to block stringent gas mileage rules enforced by the U.S. Environmental Protection Agency.

The Alliance of Automobile Manufacturers which lobbies for the likes of FCA, Ford, GM, BMW, Jaguar Land Rover, Mercedes, Mitsubishi, VW, Toyota and Mazda, didn’t want the EPA to finalize rules requiring carmakers to produce fleets averaging more than 50 mpg by 2025.

As part of the EPA’s crackdown on fuel economy, it has enforced CAFE rules for the 2017-2021 model years and was originally subject to review these rules in 2018 for the 2022-2025 model years. However, The Detroit News reports that the EPA has moved quickly to ratify the 2022-25 rules before President-elect Donald Trump takes office early next year.

A number of automakers believes that the 50 mpg rules are perhaps too ambitious and claim that the mid-term review has been “unnecessarily politicized.”
