a 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.
b 2 Wheel Drive/4 Wheel Drive. No combined figure available for this year.  

KEY: CAFE = Corporate Average Fuel Economy; GVWR = gross vehicle weight rating; kpl = kilometers per liter; R = revised; U = data are unavailable. 

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.
