The sales-weighted fuel economy of new light-duty vehicles sold in the U.S. rose to 23.8 mpg last month from 20.1 mpg in October 2007, according to researchers at the University of Michigan Transportation Research Institute.
UMTRI says the greater efficiency of the 61 million new vehicles sold during that five-year period saved about 6.1 billion gallons of fuel and reduced carbon dioxide emissions by about 120 billion pounds.
The researchers note that average new-car fuel economy in the U.S. was 14 mpg in 1923. It slid to an all-time low of 11.9 mpg in 1973 before climbing to 17.2 mpg in 1991.
