KEY: CAFE = Corporate Average Fuel Economy; GVWR = gross vehicle weight rating; kmpl = kilometers per liter; 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. These data were then converted to metric
	  units.
	  c Beginning with FY 1999,
	  the total light truck fleet ceased to be categorized by either domestic or
	  import fleets.
	  d No combined figure is
	  available for 1980. In 1980, CAFE standard for 2 wheel drive, and 4 wheel
	  drive light trucks were 6.8, and 6.0 kmpl respectively.
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.
	1.609344 kilometers = 1 mile.
	3.785412 liters = 1 gallon.
