KEY: CAFE = Corporate Average Fuel Economy; GVWR = gross vehicle weight rating; mpg = miles per gallon; N = data do not exist; 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. ,,,,,,,,,,,,,
c 2 Wheel Drive/4 Wheel Drive.  No combined figure available for this year.,,,,,,,,,,,,,
"d Beginning with MY 1999, the total light truck fleet ceased to be categorized by either domestic or import fleets.",,,,,,,,,,,,,
,,,,,,,,,,,,,
NOTE:  The fuel efficiency figures for light duty vehicles represent the sales-weighted harmonic average of the combined passenger car and light truck fuel economies.,,,,,,,,,,,,,
