Notes: "Alternative Fuel Capable" vehicles are those with the capability of being converted to an alternative fuel. The data do not confirm whether the vehicle actually completed a conversion.
The chart illustrates the annual percent change of light-duty vehicles, by fuel type, registered in the United States from 2016 through 2020. Hydrogen fuel cell vehicles (HFCVs) consistently show the greatest growth in registration counts over the four-year period. However, the base number of vehicles was very low, and the rate of increase peaked in 2019 when the registration counts of HFCVs increased by more than 60% and has been steadily decreasing since. This is likely from increased production of the Toyota Mirai and the Honda Clarity Fuel Cell models in efforts to improve market share. Plug-in hybrid electric and electric vehicles have maintained steady growth, averaging around 35% year over year for the past four years. Annual changes are more volatile for vehicle fuel types with small populations, such as hydrogen, methanol and propane. See relative vehicle population sizes at Light-Duty AFV Registrations, AFV and HEV Model Offerings, by Manufacturer, U.S. Plug-in Electric Vehicle Sales by Model, and the Energy Information Administration's Fleet and Fuel Data. For a map comparing the density of light-duty vehicles per state and charts comparing registration counts over time, see TransAtlas.
