Houston, TX, September 28, 2026 — The Trump administration has finalized new regulations that will lower fuel economy standards for automakers, impacting pollution controls for gasoline-powered cars and light trucks. The revised standards represent a significant reduction in the stringency of requirements previously set for the automotive industry.

According to the administration’s announcement, these finalized rules are projected to result in a lower fleetwide average fuel economy. The target for the average efficiency of new vehicles is now set at approximately 34.9 miles per gallon for the 2031 model year. This figure marks a decrease when compared to prior projections for the same timeframe.

The previous regulatory trajectory had aimed for higher fuel economy averages. The decision to relax these standards is expected to have implications for vehicle emissions and the overall environmental impact of the automotive sector. The administration stated these changes were intended to reduce compliance burdens on manufacturers.

Specific details regarding the precise previous projections or the exact timeline for the implementation of these new standards beyond the 2031 target were not fully detailed in the summary. Furthermore, the summary did not specify any particular automakers or companies that were involved in the development or consultation process for these standards.

The finalized standards address pollution control measures for gasoline-powered vehicles. The lowered requirements signify a shift in federal policy concerning automotive environmental performance. The decrease in the projected fleetwide average from earlier estimates indicates a potentially different path for fuel efficiency advancements in new vehicle models entering the market in the coming years.
