KEY: CAFE = Corporate Average Fuel Economy; GVWR = gross vehicle weight rating; kmpl = kilometers per liter; R = revised; U = data are not available.,,,,,,,,,,,,,,,,,,,,
,,,,,,,,,,,,,,,,,,,,
"a From 1980 to 1994, passenger car fuel efficiency includes motorcycles.",,,,,,,,,,,,
b Assumes 55% city and 45% highway-miles.  The source calculated average miles per gallon for light-duty vehicles by taking the reciprocal of the sales-weighted average of gallons per mile.  This is called the harmonic average.  These data were then converted to metric units. ,,,,,,,,,,,,
"c Beginning with FY 1999, the total light truck fleet ceased to be categorized by either domestic or import fleets.",,,,,,,,,,,,
d 2 Wheel Drive/4 Wheel Drive.  No combined figure available for this year.,,,,,,,,,,,,
,,,,,,,,,,,,
NOTES,,,,,,,,,,,,
The fuel efficiency figures for light duty vehicles represent the sales-weighted harmonic average of the combined passenger car and light truck fuel economies.,,,,,,,,,,,,
1.609344 kilometers = 1 mile.,,,,,,,,,,,,
3.785412 liters = 1 gallon.,,,,,,,,,,,,
