Trump Administration’s Fuel Economy Plans
The Trump administration plans to lower fuel economy targets for cars to 34.5 miles per gallon by 2031. This is a sharp departure from the previous goal of 50.4 miles per gallon set during the Biden administration. The primary rationale is that reducing the regulatory burden should make new cars cheaper for American drivers.
Economic Implications for Automakers and Buyers
According to government estimates, easing the standards could allow automakers to save approximately $35 billion by 2031. These savings could theoretically lead to a reduction in the average price of a new car by about $930. Automakers, especially those focused on producing SUVs and pickup trucks, support this initiative.
Hidden Costs for Consumers
However, the analysis also shows the other side of the coin. Less fuel-efficient cars will consume more fuel. According to projections, by 2050, the additional consumption could reach 100 billion gallons, costing Americans an extra $185 billion in fuel expenses.

Experts believe that any one-time savings on the purchase will be quickly eaten up by constantly rising refueling costs. As noted by Jason Schwartz from New York University:
From day one of driving, this will cost consumers more: more for gasoline, more for repairs, more time spent refueling.
For those buying a car on credit, the $930 savings will be spread over years, while higher fuel costs will be felt weekly.
Administration’s Arguments and Market Impact
Trump administration officials criticize long-term fuel cost projections, calling them speculative. They also argue that automakers will avoid fines for non-compliance with standards, which is not accounted for in the calculations. Furthermore, easing the rules could facilitate the return of less fuel-efficient cars to the market, such as powerful models with large engines, which might be perceived positively by some car enthusiasts.

This move is also seen as an attempt to counter what the administration calls an “unofficial electric vehicle mandate,” as electric cars remain expensive to produce.
Balance Between Purchase Price and Operating Costs
The question is whether the benefit of a lower initial price will outweigh years of higher vehicle maintenance costs. For many buyers, the savings may disappear long before they pay off the car.

This political debate is taking place against the backdrop of broader discussions about energy independence and environmental commitments. On one hand, regulatory relief could stimulate domestic production and savings for the industry. On the other hand, the long-term consequences for household budgets and the environment remain subjects of significant doubt. The ultimate effect will depend not only on market fuel prices but also on how quickly technology allows combining power with efficiency, regardless of regulatory pressure.
