Biden-era fuel economy rules for light-duty vehicles and medium- and heavy-duty trucks have been undone by the Trump administration, which put in place replacement standards instead. That shift determines how far American automobiles must go on a gallon of fuel going forward.
Congress created the Corporate Average Fuel Economy (CAFE) standards in 1975. These standards demand that vehicles achieve a certain minimum average miles-per-gallon figure each year. The NHTSA now estimates that under the new Trump administration rule, the fleetwide average will reach 34.9 miles per gallon by model year 2031. That projection is lower than the 50.4 miles per gallon expected under the Biden-era rules for 2031.
The Cost Claim
According to the Department of Transportation, the new regulation will reduce the typical upfront price of new vehicles by $1,300, while giving car manufacturers more freedom about what kinds of vehicles they produce. The agency adds that the rule will help Americans save $138 billion across the next five years.
What Buyers Are Paying Now
The national average price for gasoline stood at $4.48 per gallon on Monday, having risen from below $3 earlier this year. According to Kelley Blue Book, the typical new car cost $50,089, while the typical electric vehicle cost $54,813.
Industry Reactions
The Alliance for Automotive Innovation’s chief executive, John Bozzella, offered praise for the rollback. In his remarks, he referred to the standards “effectively required a switchover to electric vehicles that was out of step with market realities and customer demand.”, saying they had been weakened.
Sean Tucker, managing editor for Kelley Blue Book, doubts the new rules will affect automobile manufacturing and suggests they could be reversed down the road. He observed that carmakers “can’t move fast enough to design new cars for a regulation likely to last just two to three years.”
Ray Shefska, a co-founder of CarEdge, spoke with CBS News about the direction of car prices. His position is that automakers will not reduce their costs. He explained that sales of between 15.6 and 16.2 million new cars per year, combined with rising profit margins from looser government fuel economy rules, mean prices are likely to remain elevated.
Patrick Anderson, CEO of Anderson Economic Group, said the new rules will help automakers lower costs by aligning production with consumer demand. He also said the Trump administration’s $1,300 savings estimate is “entirely achievable.”
The Sierra Club Response
The Sierra Club’s Clean Transportation For All (CTFA) campaign is led by Katherine García, who directs it. She has spoken out against the new rules, saying “less fuel-efficient cars mean more gas burned, spending more at the pump and dirtier air in our communities.”.
Oil Consumption
On Monday, the transportation department stated that the rule would lower annual U.S. oil use in 2050 by roughly 1.3 billion barrels against 2024 levels. When the 2024 mileage standards took effect, NHTSA estimated they would cut gas consumption by 14 billion gallons by 2050.
The Political Divide
Each side is making its case as expected. The administration says the rollback ends an “illegal mandate” that forces expensive electric vehicles on buyers. Environmental advocates counter that less efficient cars burn more gas and pollute more.
Key Dates and Figures
| Milestone | Projection |
|---|---|
| Fleetwide average mpg (Biden-era) | 50.4 miles per gallon |
