The Trump administration on Monday finalized a rule rolling back Biden-era fuel economy standards for new cars and light trucks, fulfilling a promise President Donald Trump made to lower vehicle prices. The Transportation Department’s “Freedom Means Affordable Cars” rule cuts the fleet-wide fuel economy target for model year 2031 from 50.4 miles per gallon under the Biden standards to 34.9 miles per gallon. It also eliminates what the administration describes as a requirement that effectively pushed automakers to build electric vehicles.
Trump announced over the weekend that he had approved the new standards, saying on Truth Social that they would “take the waste out of building cars in America. That means LOWER PRICES, saving families thousands on a new, beautiful, and safe car.” The administration estimates the change will reduce the average cost of a new vehicle by about $1,300 and save Americans $138 billion over five years. Transportation Secretary Sean Duffy said the department had “finally ended the illegal mandate that forced automakers to produce more expensive electric vehicles that American families didn’t want.”
Details & Background
Corporate Average Fuel Economy standards, known as CAFE, set the average miles per gallon each automaker’s fleet must reach. Under President Joe Biden, the standards required roughly 2% annual improvements, while the new rule requires about 1% per year. The Trump administration first unveiled its plan in December 2025, arguing the Biden rules exceeded the authority Congress gave regulators. That proposal also called for ending the CAFE credit trading program and reclassifying crossovers and small SUVs as passenger cars rather than light trucks.
The rollback comes as car prices remain a major burden for families. The average new vehicle cost $49,855 in July 2026, according to figures cited by ABC News. The administration argues that cheaper cars will also mean safer roads, because more families will be able to replace older vehicles. “Newer cars are safer cars. By reducing vehicle prices, more American families will be able to afford newer vehicles,” said National Highway Traffic Safety Administration Administrator Jonathan Morrison.
Reactions
The auto industry welcomed the decision. The Alliance for Automotive Innovation called it “an appropriate course correction,” with CEO John Bozzella saying the previous standards “effectively required a switchover to electric vehicles that was out of step with market realities and customer demand.” Duffy said the new standards are “commonsense guidelines” and that the administration is “delivering relief to families and reviving the beating heart of American manufacturing.”
Environmental groups sharply disagreed. The Environmental Defense Fund argued drivers would spend an average of $1,400 more on gas and warned of “wasted gas, more pollution, and higher costs.” Dan Becker of the Center for Biological Diversity said the change would hurt consumers “at the pump and at the doctor’s office,” and former EPA Administrator Gina McCarthy said, “For fifty years, fuel economy standards have saved Americans money and cut pollution at the same time.” The Sierra Club also warned of higher gas use and air pollution.
Why This Matters to You
For families shopping for a new car or truck, federal rules have a direct effect on sticker prices. The administration says loosening the mileage mandate will let automakers build the vehicles Americans actually want to buy, at lower cost, rather than forcing more expensive electric models onto dealer lots. If the promised $1,300 in average savings holds up, that could make a real difference for working families already stretched by high prices.
The fight is far from over. Critics argue the savings at the dealership will be offset by higher fuel costs, and environmental groups have made clear they will keep fighting the change. But Monday’s rule marks one of the clearest breaks yet with the Biden administration’s climate agenda and a major shift in how Washington regulates the auto industry. For American drivers, manufacturers and workers, the decision will shape the cars on the road for years to come.
