Trump Finalizes Weaker Fuel-Economy Rules for 2022-2031 Vehicles

The Trump administration finalized a rule Sept. 28, 2026, loosening pollution limits for gasoline cars and light trucks from model years 2022-2031. The Transportation Department calls it 'Freedom Means Affordable Cars.' It reverses Biden-era fuel-efficiency increases, cutting required yearly gains to a fraction of a percent. Disputes over emissions, costs, and state enforcement are likely.
