This chart shows the number of light-duty alternative fuel vehicles (AFVs), hybrid electric vehicles (HEVs), and diesel models offered by vehicle manufacturers from 1991 through 2019. Vehicles capable of using E85 (up to 85% ethanol, 15% gasoline) have represented the largest share of models offered from 2003 until 2017, when electric vehicles (EVs) overtook them. This was largely because the technology required for E85 vehicles is comparatively inexpensive and compatible with gasoline vehicles. 2016 was the first quantitative decrease in the number of new AFVs offered after five years of steady increases. Contributing factors to this decrease could be low gasoline prices, the Volkswagen diesel emissions scandal, and the phase-out of Corporate Average Fuel Economy (CAFE) credits for flexible-fuel vehicles (FFVs). Since then, increases in EV offerings have made up for the loss in E85 offerings.
