KEY: CAFE = Corporate Average Fuel Economy; GVWR = gross vehicle weight rating; mpg = miles per gallon; R = revised; U = data are unavailable.
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 No combined figure is
available for 1980. In 1980, CAFE standard for 2 wheel drive, and 4 wheel
drive light trucks were 16.0, and 14.0 mpg respectively.
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.
