Maps and Data

This figure illustrates the population breakdown of alternative fuel vehicles (AFVs) registered in the United States as of December 31, 2023. Most of the vehicles are flexible fuel vehicles (FFVs), but those generally operate primarily on conventional gasoline. FFVs were produced and sold as a way for vehicle manufacturers to meet their fuel economy requirements. Hybrid electric vehicles (HEVs) are the second largest population by fuel type, accounting for 50% of the AFV population when excluding FFVs. Electric vehicles (EVs) account for about 22% of the AFV population when excluding FFVs. For a map comparing the density of light-duty vehicles per state and charts comparing registration counts over time, see TransAtlas.
