Donald Trump announces new fuel economy standards to replace Biden-era mandates

On September 27, 2026, U.S. President Donald Trump announced via the Truth Social platform the approval of new fuel economy standards. These regulations formally terminate the mandatory framework previously established by the Joe Biden administration regarding electric vehicle production requirements.

Trump stated that these changes will reduce unnecessary manufacturing costs, allowing American families to save thousands of dollars on new, safe vehicles. The policy shift reverses the Biden administration's strategy, which had sought to pressure automakers into producing more electric vehicles to meet strict efficiency targets. The administration had previously signaled its intention to modify these standards last month, aiming to eliminate what it described as wasteful mandates on the automotive industry.
