In 1975, only three percent of all new cars had a fuel economy above 25 miles per gallon (mpg), but by 2014, 73% did. Great improvements were made in the fuel economy of cars from 1975 to 1985, so that by 1985 most of the cars produced had a fuel economy above 20 mpg. Light truck fuel economy showed an improvement during that same time period, so that by 1985 most light trucks produced had a fuel economy above 15 mpg. Due to more recent improvements, 40% of cars produced in 2014 have a fuel economy above 30 mpg and half of light trucks were over 20 mpg.
