FACT FOCUS: Trump said weaker gas mileage rules will mean cheaper cars. Experts say don’t bet on it
By ALEXA ST. JOHN
DETROIT (AP) — President Donald Trump this week announced plans to weaken rules for how far automakers’ new vehicles need to travel on a gallon of gasoline, set under former President Joe Biden.
The Trump administration said the rules, known formally as Corporate Average Fuel Economy, or CAFE, standards, are why new vehicles are too expensive, and that cutting them will drive down costs and make driving safer for Americans.
The new standards would drop the industry fleetwide average for light-duty vehicles to roughly 34.5 mpg in the 2031 model year, down from the goal of about 50.4 mpg that year under the Biden-era rule.

Here are the facts.
Affordability
TRUMP: EV-friendly policies “forced automakers to build cars using expensive technologies that drove up costs, drove up prices and made the car much worse.”
THE FACTS: It’s true that gas mileage standards have played a role in rising vehicle prices in recent years, but experts say plenty of other factors have contributed, and some much more.
