Model year 2006 cars and light trucks are the fastest and heaviest since 1975, yet they average the same 21.0 miles per gallon they got last year, according to the U.S. Environmental Protection Agency's (EPA) annual fuel economy trends report released today.
But the 21.0 mpg average fuel economy for cars and light trucks is five percent lower than the average fuel economy peak value of 22.1 mpg achieved in 1987-1988."
