Well, Ill take some heat with ya.....Im the popular guy just so you know
Anyway I think it wouldnt be to far fetched, can you imagine a Mustang that is all wheel drive and has 400hp at its disposal? Although only the 3.5 is AWD compatible, the Eco-Boost engine can easily be pushed passed the 400hp mark.
So Why not I say, maybe introduce it as a Special Edition V6 model and see where it goes. Would improve performance to a level the competition would either have to adapt to, or just concede to !!!!
