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.
