Average fuel consumption for new U.S. vehicles has improved in recent years, reaching a record high of 27.1 miles per gallon (mpg) for model year 2023 vehicles[6]. Over the past two decades, fuel efficiency for new models increased significantly, with new 2022 models averaging 26.4 mpg, up from 19.5 mpg in 2002[2]. Cars specifically saw fuel efficiency rise to 33.3 mpg in 2022, while trucks improved to 23.4 mpg[2].
Improvements in fuel economy are attributable to tougher standards and the growing adoption of electric vehicles, plug-in hybrids, and high-efficiency hybrids[5]. These advances have contributed to lower average fuel consumption and reduced annual gasoline expenses for U.S. drivers[2].
Fuel economy varies significantly by type and weight of vehicle:
- Light-duty cars (new): ~27.1 mpg (MY2023 average)[6]
- All new vehicles (2022): 26.4 mpg[2]
- Light trucks: around 16.2 mpg overall, but modern pickups and SUVs are improving[4]
- Medium trucks: 8 mpg[4]
- Heavy trucks: 5.8 mpg[4]
These figures reflect ongoing improvements, but actual fuel consumption depends on specific vehicle model, driving habits, and maintenance. Continued advances in vehicle technology and policy are expected to further increase average fuel economy in the coming years[6].
