Americans continue to look for fuel-efficient vehicles when they go car shopping.
The average fuel economy – what is on the window sticker of a new car -- of new vehicles sold in the U.S. in October was 24.1 mpg -- the highest level yet. It was up 4 mpg, or 20%, from October 2007, according to the University of Michigan Transportation Research Institute.
The 24.1 mpg is up from 23 mpg in October a year ago and from 22.3 mpg in the same month in 2010.
Researchers at the institute said their numbers are adjusted to include the new ratings – down in most cases by 1 to 2 fewer miles per gallon depending on the vehicle – for the Hyundais and Kias that the Environmental Protection Agency found had inflated mileage ratings.
