AWD is not all about driving in the snowbelt. In the case of the Mustang, it is also about putting power down for acceleration. Many of those who park their Mustangs for the winter do so to protect it from salt, slush and grime....not because of traction. After owning and drag racing several different Mustangs, I think AWD would be very attractive for both traction and safety. It is pretty easy for a 480 HP or more RWD vehicle to become very squirrelly especially in the hands of an inexperienced driver. It is no accident that the upcoming Dodge Chargers will be AWD. Same could be said for high performance Porsches, BMWs, Audis, etc. Of course, mid-engine would also solve the traction problem, as in the Corvette, but it seems to me that AWD would make more sense.
