NHTSA finalizes rollback of Biden-era fuel economy standards
The Department of Transportation announced Monday that the National Highway Traffic Safety Administration has finalized new corporate average fuel economy rules, replacing Biden-era targets. The previous standard called for new vehicles to average 50.4 miles per gallon by 2031; the new rule lowers that requirement to 34.9 miles per gallon.
GoKawiil's interpretation of the reporting above, not reported fact.
The administration argues the change will lower new-car prices by easing compliance costs for automakers, though that outcome is not guaranteed and depends on how manufacturers respond. A lower fuel-economy bar could reduce pressure on automakers to invest in electrification and lightweight technology, with potential consequences for fuel costs to consumers and emissions over time.
