Apparently the new 5.0 mustang makes 412 bhp (essentially the same as the M3) but it delivers 26 mpg. I guess this why direct injection is the future.

It's not that I can't afford the extra fuel, but I'd love to not have to stop for fuel twice a week. Oh and no I don't want a bigger fuel tank, the car is heavy enough.
