Trump fuel economy rollback saves automakers $60 billion in tech costs
The U.S. Transportation Department finalized a rule reducing fuel economy standards for automakers, cutting $60.6B in tech costs through 2031. The rule sets a 34.9 mpg fleet average by 2031, down from 50.4 mpg under Biden's rule. The Alliance for Automotive Innovation, including GM, Toyota, and Ford, supports the decision. The rule also eliminates a credit trading program and phases out certain efficiency credits. Stellantis faced $775M in fines for noncompliance.
