Trump Rolls Back Fuel Economy Standards. Will Cars Really Get Cheaper?
When it was first proposed in December 2025, the rule was divisive, drawing ire from environmental advocates while garnering praise from auto-industry trade groups. The Administration finalized it last week with a signoff from President Donald Trump.
The President commented on the forthcoming rule Sept. 26, saying the new standards would “take the waste out of building cars in America.”
“That means LOWER PRICES, saving families thousands on a new, beautiful, and safe car,” he wrote on Truth Social.
The claim that the revisions will pass down cost savings to American buyers, however, relies on several factors, including automakers’ pricing decisions, fuel costs, and broader economic conditions.
What changes under Trump’s new fuel economy rule?
Former President Joe Biden’s regulations were put in place in 2024 to reduce car-based greenhouse gas emissions, decrease dependence on fossil fuels, and spur a transition to electric and hybrid vehicles. The Trump Administration has claimed that its revisions are more focused on bolstering the auto industry and making safer, newer cars more accessible.
