a Excludes gasoline-electric and diesel-electric hybrids because the input fuel is gasoline or diesel rather than an alternative transportation fuel. The Department of Energy, which has Energy Policy Act implementation authority, ruled that gasoline-electric and diesel-electric hybrids are not "alternative fuel vehicles."
b The remaining portion of 85-percent ethanol is gasoline.
c In 1997, some vehicle manufacturers began including E85-fueling capability in certain model lines of vehicles.  For 2007, the EIA estimates that the number of E-85 vehicles that are capable of operating on E85, gasoline, or both, is about 7.1 million.  Many of these alternative-fueled vehicles (AFVs) are sold and used as traditional gasoline-powered vehicles.  In this table, AFVs in use include only those E85 vehicles believed to be used as AFVs.  These are primarily fleet-operated vehicles.
d May include P-Series fuel or any other fuel designated by the Secretary of Energy as an alternative fuel in accordance with the Energy Policy Act of 1995.
Notes:  Vehicles in Use do not include concept and demonstration vehicles that are not ready for delivery to end users.  Vehicles in Use represent accumulated acquisitions, less retirements, as of the end of each calendar year.  The estimated number of neat methanol (M100), 85-percent methanol (M85), and 95-percent ethanol (E95) vehicles in use is zero for all years included in this table.  Therefore, those fuels are not shown.
