**[U.S. Significantly Eases Fuel Economy Standards, Undermining Biden's EV Policies]** According to a report by Jinse Finance, on September 28, the Trump administration finalized measures to significantly weaken federal automotive fuel economy standards, rolling back a key policy that had previously encouraged the auto industry to improve the efficiency of cars and trucks and boost sales of battery electric vehicles. The U.S. Department of Transportation stated on Monday that automakers must achieve an average fuel economy of 34.9 miles per gallon for passenger cars and light trucks by the 2031 model year. This standard is far lower than the approximately 50 miles per gallon requirement finalized during former President Joe Biden's administration. This move advances Trump's efforts to weaken federal policies that had previously driven the auto industry to enhance the efficiency of fuel-powered vehicles (cars and trucks) and expand electric vehicle sales. President Trump had repeatedly criticized these measures, calling them an "EV mandate" that drove up new car prices and labeling the policies as "overly burdensome and utterly ridiculous." U.S. Transportation Secretary Elaine Chao stated that the adjustment aims to lower new car prices, making them more affordable for consumers.
