Study finds that increased vehicle travel and decreased occupancy have undercut the impact of improving fuel economy over last 40 years

Green Car Congress

Sivak found that while the vehicle fuel economy of the entire light-duty fleet improved by 40% (from 13 mpg US to 21.6 l/100km), because of the decrease in vehicle load, the occupant fuel economy only improved by 17% (from 24.8 Combining these two effects yields a reduction of about 14% in the amount of fuel used.
