Table 4-23: Average Fuel Efficiency of U.S. Passenger Cars and Light Trucks
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.
