  aExcludes gasoline-electric and diesel-electric hybrids.
  bThe remaining portion of 85-percent ethanol is gasoline.
  cExcludes E85 vehicles used by private individuals (non-fleet users) because most of those are believed to be in use as traditional gasoline-powered vehicles. 
  dMay 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.  Light duty includes vehicles less than or equal to 8,500 pounds Gross Vehicle Weight Rating (GVWR). Medium duty includes vehicles 8,501 to 26,000 pounds GVWR. Heavy duty includes vehicles 26,001 pounds and over GVWR.  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.
