DOD Finalizes 'Freedom Means Affordable Cars' Rule, Setting 2031 Fuel Target at 34.9 MPG

Key points

• The new rule sets a 2031 fleet average fuel economy target of 34.9 mpg, down from the previous 49.3 mpg target.
• The administration projects the rule will lower average new vehicle costs by $1,300 and save consumers $138 billion over five years.
• The rule eliminates the CAFE credit trading program starting in 2028 and reclassifies vehicle categories to favor passenger cars over light trucks.
• Independent analysts doubt the administration's claim that the rule will significantly reduce car prices for consumers.
• The rule is expected to reduce yearly oil consumption by 1.3 billion barrels by 2050 compared to 2024 levels.

Background

This development follows President Trump's approval of weaker fuel standards on September 26, 2026, which replaced Biden-era rules requiring 50.4 mpg by 2031. The new standards effectively end federal mandates favoring electric vehicle adoption, shifting auto policy toward market forces. Critics have noted that recent legislative changes may limit the enforcement power of these new standards.

How outlets are covering it

The Department of Transportation, led by Secretary Sean Duffy, frames the rule as a consumer protection measure that ends an 'illegal EV mandate' and promotes affordability. In contrast, The Washington Post reports that independent analysts are doubtful that the rule will actually lower car prices for consumers. Yahoo Finance highlights potential cost savings for manufacturers like GM, estimating a $20 billion reduction in technology costs through 2031, but does not confirm consumer price impacts. The administration emphasizes safety and consumer choice, while critics question the economic feasibility of the projected savings.

Why it matters

This rule significantly alters U.S. automotive policy by reducing fuel efficiency requirements and eliminating EV-related incentives. It could impact vehicle prices, consumer choices, and the automotive industry's investment in electric vehicles. The outcome will affect consumer costs, environmental goals, and U.S. competitiveness in the global EV market.

What to watch

The rule will take effect for model years 2022 to 2031, with specific changes to vehicle classification starting in 2030. The CAFE credit trading program will be eliminated starting in 2028. The administration will monitor the rule's impact on vehicle prices and consumer savings, while analysts and critics will assess whether the projected benefits materialize.
