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 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.
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.
