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 imported 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.
