\a\ Values are rounded to thousands. Accordingly, these estimates are
not
equal to the sum of Federal fleet data (for which exact counts are
available)
and non-Federal fleet estimates (rounded to thousands).
\b\ The remaining portion of 85-percent methanol and both ethanol fuels is gasoline. \c\ In 1997, some vehicle manufacturers began including E85-fueling capability in certain model lines of vehicles. Those vehicles are capable of operating on E85, gasoline, or both. Alternative fuel vehicles (AFV's) in use include only those E85 vehicles believed to be intended for use as alternative-fuel vehicles (AFV's). These are primarily fleet-operated vehicles. All of the E85 vehicles are included in the data for "AFV's made available." Note: Estimates for 1998-2000 have been revised since their original publication in October 1999. The revision reflects new data for the Federal sector only. Estimates for 1999 are preliminary and estimates for 2000, in italics, are based on plans or projections. Estimates for historical years may be revised in future reports if new information becomes available.
