Michael Sivak on fuel economy

May 10, 2009

Little progress in fuel economy since 1923

Vehicles on America's roads today get only about three miles more per gallon than vehicles back in 1923, University of Michigan researchers say.

A new study in the journal Energy Policy by Michael Sivak and Omer Tsimhoni (formerly) of UMTRI's Human Factors Division shows that overall fuel economy for vehicles in the United States was 14 miles per gallon in 1923 and 17.2 mpg in 2006.
