Trump slashes auto fuel standards to 34.5 mpg, gutting EV mandates

Key points

• Trump announced the new fuel economy standards via Truth Social, framing them as a victory for auto manufacturers and consumers.
• The new CAFE standards require an average of 34.5 mpg by 2031, a significant drop from the previous 50.4 mpg target.
• Transportation Secretary Sean Duffy confirmed the move, stating a major victory for auto workers is coming.
• The final rule text was not immediately available, and White House officials did not respond to questions.
• The policy change is part of a broader effort to dismantle Biden-era electric vehicle policies.

Background

This development follows a series of rollbacks of Biden-era climate and energy policies. In February 2026, the EPA scrapped all climate rules for motor vehicles, including the scientific finding that underpinned them. Additionally, Congress passed the One Big Beautiful Bill Act, which repealed noncompliance penalties for failing to meet fleetwide fuel economy averages. This legislative change transformed CAFE standards from mandatory requirements into voluntary suggestions, as noted by University of Maryland professor Joshua Linn.

How outlets are covering it

Politico emphasizes the political context, noting the move comes amid scrutiny over high gas prices and rising car costs ahead of midterm elections. It highlights that the new standards are less impactful than the EPA's earlier repeal of climate rules due to the removal of penalties. CNBC focuses on the business implications, stating that weaker standards allow automakers to produce more profitable pickup trucks and SUVs, while making electric vehicles less attractive. However, CNBC notes that some companies, like General Motors, have stated they will continue to make electric vehicles. Critics, such as Dan Becker of the Center for Biological Diversity, argue that the policy weakens U.S. competitiveness against global trends favoring Chinese advanced technology electric vehicles.

Why it matters

The new fuel economy standards signal a definitive shift away from federal mandates for electric vehicle adoption in the United States. By lowering efficiency targets and removing penalties for non-compliance, the policy allows automakers to prioritize more profitable, less efficient vehicles. This move widens the gap between U.S. transportation policy and global trends, potentially impacting the competitiveness of the U.S. auto industry in the global market.

What to watch

The final rule is expected to be detailed further, with Transportation Secretary Sean Duffy indicating a major announcement is coming Monday. The new standards will likely face legal challenges, similar to the EPA's repeal of vehicle emissions rules. Automakers will decide whether to meet the new standards based on business considerations, as there are no penalties for non-compliance. The policy may also influence consumer behavior and market trends for electric vehicles in the coming years.
