KEY: CAFE = Corporate Average Fuel Economy; GVWR = gross vehicle weight rating; kmpl = kilometers per liter; 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-kilometers. The source calculated average kilometers per liter for light-duty vehicles by taking the reciprocal of the sales-weighted average of liters per kilometer. 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.
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.
Numbers may differ slightly from previous year's metric tables because a higher precision conversion factor was used.
