Trump approves vehicle fuel-economy rules; final text is pending
President Donald Trump says he approved new fuel-economy standards for passenger vehicles, but the final rule has yet to be published. Transportation Secretary Sean Duffy pointed to a fuller announcement on Monday. The proposal would lower the model-year 2031 fleet average from the Biden-era 50.4 to about 34.5 miles per gallon. Automakers still need the final text to know which target the rule sets.

Approval without the final rule
President Donald Trump said on September 26 that he had approved new fuel-economy standards for passenger vehicles. The announcement concerns rules intended to replace stricter standards from the Biden administration. The final rule text was not yet available when the reports appeared, so the approval establishes a policy decision without yet supplying the exact requirement manufacturers will face. Transportation Secretary Sean Duffy pointed to a fuller announcement on Monday. For now, the immediate development is the administration's approval claim and the wait for its published terms. Until those terms appear, the public cannot read the final standard from the announcement alone.[1], [2]
The proposal gives a scale, not a final number
An earlier National Highway Traffic Safety Administration proposal would set the fleet average at about 34.5 miles per gallon for model year 2031. The Biden-era rule it would replace called for 50.4 miles per gallon. POLITICO described the expected reduction as nearly a third, but that comparison belongs to the proposal: the published final text may settle the number differently. A fleet average sets a target for the mix of vehicles a manufacturer sells; it does not require every individual car to achieve the same mileage figure. The announced approval gives direction to the policy; the measurable requirement still depends on the document that follows.[1]
Enforcement and the next document
The standard's practical force is another question. University of Maryland professor Joshua Linn told POLITICO that last year's removal of penalties for noncompliance had made the standards closer to a request without a fine. Environmental campaigner Dan Becker argued that easing the rule could leave Detroit less competitive as other markets move toward Chinese electric vehicles. Those are their assessments, not findings established by the approval post. Congress also cut consumer tax incentives for electric vehicles last year, placing the fuel-economy change in a broader shift in US vehicle policy. The White House had not immediately answered POLITICO's questions. Monday's promised detail should show what the administration actually approved, before any court challenge tests the text.[1]
