Trump Says He Is Rolling Back Biden-Era US Fuel Economy Rules for Cars

US President Donald Trump said he is rolling back fuel economy rules for cars that were put in place during the Biden administration, framing the move as the end of what he called an "EV mandate."

Trump said the previous rules had steered consumers toward purchasing electric vehicles, and that his administration would reverse that approach. The announcement continues a broader pattern of the administration revisiting environmental and automotive regulations enacted under the prior administration.

Fuel economy standards set requirements for how efficiently vehicles must use fuel, and previous administrations have used them as a lever to encourage automakers to expand production of electric and hybrid vehicles. Rolling back such rules would ease compliance requirements for manufacturers that continue to produce traditional combustion-engine vehicles.

The move is likely to draw reactions from environmental groups, who have generally supported stricter fuel economy standards as a tool for reducing vehicle emissions, as well as from parts of the auto industry that have invested heavily in electric vehicle production in response to the earlier rules.

Further details on the specific scope of the rollback and its implementation timeline were not immediately outlined in the president's remarks.
