The Trump administration on Monday released a final rule that substantially weakens federal fuel economy standards for gasoline-powered cars and light trucks, marking a sharp reversal of Biden-era regulations. The move, which the administration frames as eliminating a “backdoor EV mandate,” is the latest step by Trump and Republican allies to undo incentives for automakers to produce electric vehicles—even as China dominates the global EV market. The new rules were released shortly after President Donald Trump rejected an Iranian proposal to open the Strait of Hormuz, sending oil prices soaring.
According to the administration, the relaxed standards will better align regulations with current market conditions and the law. The Alliance for Automotive Innovation, a trade group representing General Motors, Toyota, Volkswagen, Hyundai, Ford, and other major automakers, said it is “still reviewing the final rule, but NHTSA made the right call to better align fuel economy standards with the law and current market conditions.” The group’s support signals that automakers may welcome the flexibility, though critics argue the rollback will have severe consequences.
Environmental and consumer advocates warn that the new standards will lead to higher costs and more pollution. “For decades, our national fuel economy standards have steadily made our vehicles more efficient and less expensive to drive,” said Andy Su, Senior Transportation Attorney at the Environmental Defense Fund. “Now these Trump administration rules will be a sharp U-turn that will mean wasted gas, more pollution, and higher costs for Americans who are already struggling with high fuel prices.” The rollback is expected to increase gasoline consumption and tailpipe emissions, undermining efforts to combat climate change.
The final rule also cuts EV credits, further discouraging electric vehicle adoption. This comes at a time when China is aggressively expanding its EV market and global influence. While the administration argues the changes will reduce regulatory burdens and lower vehicle prices, critics contend that the long-term costs—both environmental and economic—will be significant. As the 2026 midterm elections approach, the fuel economy rollback is likely to remain a contentious issue, with automakers, environmental groups, and consumers all weighing in on its impact.
