r Revised.

a 55% city, 45% highway miles sales weighted harmonic average.

b Sales-weighted harmonic average of the combined passenger car and light truck fuel economies.

c 2WD/4WD. No combined figure available for this year.

N Data are nonexistent.

U Data are unavailable.

Note: GVWR= Gross vehicle weight rating.

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.
