Conversion models were counted for natural gas and propane vehicles for the first time in 2012.

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 2012. In 2012, vehicles capable of using E85 represent the largest share of models offered. This is largely because the technology required for E85 vehicles is comparatively inexpensive and compatible with gasoline vehicles.
