On September 28, it was reported that the Trump administration has finalized a significant rollback of federal fuel economy standards for vehicles, withdrawing a policy that aimed to push the automotive industry to improve energy efficiency and increase sales of battery electric vehicles. The U.S. Department of Transportation announced on Monday that automakers will be required to achieve an average fuel economy of 34.9 miles per gallon for passenger cars and light trucks by the 2031 model year, far below the standard of approximately 50 miles per gallon set during the Biden administration. This move is part of the Trump administration's efforts to weaken federal policies, which he has repeatedly criticized as 'electric vehicle mandates,' claiming they drive up new car prices and impose excessive burdens. U.S. Transportation Secretary Duffy stated that the adjustment of standards aims to lower new car prices and make them more affordable for consumers.
