Miles per gallon
|Average U.S. passenger car fuel efficiency (calendar year)||New vehicle fuel efficiency (model year)||CAFE standards (model year)|
|Passenger car||Other 2-axle 4-tire vehicle||Passenger car||Domestic passenger car||Imported passenger car||Light truck (<8,500 lbs GVWR)||Passenger car||Light truck|
KEY: CAFE = Corporate Average Fuel Economy; GVWR = Gross vehicle weight rating; U = Data are unavailable.
NOTES: New vehicle fuel efficiency and CAFE standards assume 55% city and 45% highway-miles. The fuel efficiency figures for light duty vehicles represent the sales-weighted harmonic average of the combined passenger car and light truck fuel economies.
Beginning with model year 2008, Light truck manufacturers have the option to comply with the unreformed standard values or the new reformed standard values based upon each manufacturers unique vehicle fleet characteristics. In model years 2008-2010, the values shown for CAFE standards for Light truck are the standard values applicable under the existing "unreformed" CAFE program.
