Well, i doubt any fox body is doing that, but the new dodge charger/magnum/300 srt8's w/ the 6.1 425 hp hemi might get close to 20mpg highway, but keep in mind these engines only run w/ 4 cylinders on the highway to reduce fuel consumption.

I may be off your original question though. Do you have a specific stang your looking to get better MPG with? need more info
