Trump promised his mileage standards would make cars cheaper and safer. New documents raise doubts about that.

Washington Post logoTop Senate Democrat argues that revised rule “will lead to vehicles that are neither safer, nor more affordable or fuel-efficient.”

President Trump has said his plan to weaken federal mileage standards would make cars cheaper and “substantially safer.” But the administration’s own analysis suggests that it would cost consumers more than it would save them in the long run, and would do little to make the nation’s roads safer.

The revised Safer Affordable Fuel-Efficient (SAFE) Vehicles rule, which has not been released publicly, would require automakers to increase the average fuel efficiency of the nation’s fleets by 1.5 percent per year between model years 2021 and 2026. Rules put in place by the Obama administration, by comparison, require a nearly 5 percent annual increase.

If finalized, the proposal would mandate more progress on fuel efficiency than the Trump administration’s initial effort to freeze fuel standards in the years ahead.
