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 miles per gallon, the highest level yet. It was up 4 mpg, or 20 percent, 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.
