CAFE standards only apply to "light duty" vehicles. Note that if you purchase an F-250 or an F-350 mpg is NOT on the window sticker. (Light duty vehicles = vehicles weighing less than 8800 lbs.) About the only thing that is regulated is the tailpipe emissions, but the fuel consumption is not.
Really its only now that medium and heavy duty vehicles are even remotely being considered for some sort of mileage standard.
