"Third, CAFE mpg is very different from the fuel-economy-label mpg numbers on every new car. That’s because the CAFE figures are based on the original city and highway fuel-economy tests established in the Seventies, while the window-sticker numbers combine those values, along with the results of three other emissions tests, to produce mpg figures that better-match real-world driving. In general, the combined mpg on a vehicle’s label is about 20 percent lower than the CAFE mpg."
