What to know

  • DOT finalized new CAFE standards cutting the required fleet average from a Biden-era target of 50.4 mpg by 2031 to about 34.9 mpg and dropping extra credit for EVs.
  • The administration says the change will lower new vehicle prices, but analysts say real savings depend on fuel costs and broader economic conditions.
  • Critics say the rollback will raise pollution and fuel costs and further cede ground on EV competitiveness to other countries.
  • The rule was released just after Trump rejected an Iranian proposal on the Strait of Hormuz, a move that sent oil prices sharply higher.

The rollback is bad policy that makes the US dirtier and less competitive globally on climate and EVs.

America's truck-and-SUV culture is irrational and wasteful, driven by status rather than need.

US road infrastructure and driving conditions make smaller, less powerful vehicles impractical or unsafe.

      The Trump administration released new fuel economy standards today, relaxing regulatory requirements for automakers, and reverting to the dark ages compared to the rest of the civilized world. Under Trump, are we still actually part of that civilized world? I think not.

    • We already are. We saw the US auto industry go through a bifurcation several years ago in response to the toxic approach of US lawmakers towards EVs. They started the transition, but then quickly realised it was easier to just separate out the US and regress there. 98% of new cars sold in Norway are EVs. About 30% of new cars sold in the UK are…

Still unanswered
  • Will the rollback actually lower new-car prices given rising fuel costs?
  • How will automakers that had invested in EV production respond to the removal of EV credits?
