U.S. Department of Transportation significantly relaxes fuel efficiency standards and reconsiders EV promotion measures

On the 28th, the US Department of Transportation announced new standards that significantly relax fuel efficiency standards for automobiles. This is part of a review of the previous Biden administration's electric vehicle (EV) promotion policies. "We have ended illegal regulations that force the production of expensive electric vehicles that American families don't want," Transportation Secretary Duffy said in a statement. The headwinds against EVs that have continued since the inauguration of the second Trump administration are likely to become even stronger, affecting the strategies of manufacturers.

The new standards require automakers to average 34.9 miles per gallon for 2031 cars and light trucks. This is a significant reduction from the previous 50 miles (approximately 21 km).

In addition, a system that allows manufacturers to turn surplus fuel into credits when they exceed fuel efficiency regulations and sell them will be abolished starting with the 2028 model year, as it is advantageous to EV manufacturers. Vehicle classification will also be reviewed, and vehicles primarily used to transport people, such as some crossover vehicles that were classified as light trucks, will be classified as passenger cars.
