The US Department of Transportation has finalized new fuel efficiency standards, marking a significant shift in federal automotive policy. The administration characterizes this move as one of its most substantial deregulatory efforts to date, effectively replacing the previous targets established during the Biden era.
Under the new mandate, the required fleet average fuel economy is set to reach 34.9 miles per gallon. This target represents a modest increase from the 30.1 miles per gallon previously established for the 2024 model year, while abandoning the earlier goal of 50.4 miles per gallon by 2031.
The administration estimates that these changes will reduce the average price of a new vehicle by $1 300, potentially generating $138 billion in savings over the next five years. However, these projections remain a subject of debate among various industry analysts and advocacy groups.
Automakers have expressed support for the revised regulations. Conversely, environmental and consumer advocacy organizations argue that the lower standards will lead to increased fuel expenditures for drivers, alongside broader public health costs and environmental impacts associated with higher emissions.
Previous standards, which were discarded by the current administration, were projected to save consumers over $600 in gasoline costs over the lifetime of a vehicle. The total fuel savings under the former policy were estimated at $23 billion.
