The Department of Transportation (DOT) recently determined that the Biden administration exceeded its authority by factoring electric vehicles into its fuel economy guidelines, according to TheStreet.
That reversal could cost drivers the $600 in annual gas savings that the original Biden-era rules were expected to deliver.
What changed?
In 2024, the Biden administration finalized rules requiring automakers to boost fuel efficiency by about 2% annually for passenger cars from 2027 through 2031, and for SUVs and light trucks from 2029 through 2031.
TheStreet reports these tighter standards were expected to save drivers more than $600 a year at the pump.
The DOT contends that federal law prohibits factoring electric vehicle adoption into fuel economy calculations, making the Biden-era assumptions invalid.
This decision paves the way for the Trump administration to roll back the Biden-era rules and introduce looser standards.
How $600 affects the typical budget
Missing out on $600 in savings means an extra hit of about $50 a month or roughly $12.50 a week.
On average, U.S. households spend about $2,148 per year on gasoline, based on the U.S. Energy Information Administration’s (EIA) analysis of the Consumer Expenditure Survey (CES). Any increase in fuel costs can add extra strain for families managing tight budgets.
In a DOT statement shared via TheStreet, Transportation Secretary Sean Duffy said the goal is to keep cars more affordable and easier to manufacture in the U.S.
He argued that the “previous administration illegally used Corporate Average Fuel Economy (CAFE) standards as an electric vehicle mandate,” a move he believes could have driven up prices or reduced the number of models available to buyers.
Practical ways to use less fuel
While federal rules are out of drivers’ hands, small daily choices can help stretch each gallon:
- Maintain your car: Inflate tires properly, replace air filters, and follow the manufacturer’s oil recommendations.
- Drive smoothly: Avoid abrupt starts and stops; use cruise control to maintain steady speeds on highways.
- Plan wisely: Combine errands, share rides, and see if your workplace offers carpool benefits.
Weigh financial impacts before replacing your car
Buying a more fuel-efficient car can involve extra expenses such as higher insurance, taxes, and depreciation.
For households with a paid-off, reliable vehicle, ongoing maintenance costs are often lower than the total cost of a new purchase.
Fuel price outlook
It’s uncertain how long the revised standards will remain in place, but households may want to monitor gas use and set aside about $50 a month as a buffer. If prices hold steady, that money can be used for other needs.
Small changes, such as adding a remote workday or using free grocery pickup, can help reduce unnecessary trips and fuel stops. Daily habits still play the biggest role in managing fuel expenses.
