I have had some ideas about AWD that I think would be intersting.
As far as I know GM does not have any kind of AWD drivetrain that could go in the bonnes but some other makes do.
The Mitsibuishi(sp????) 3000GT VR-4 was AWD with a transverse motor. The last year these cars were made they were pushing 325 HP through all four wheels with twin turbos and a 6-speed manual.
I know this sounds like complete blasphemy but I think it would be a hell of a drivetrain. The drivetrain from the 3000GT is the only car I can think of that is a transverse set up and puts out the kind of power we would want. Getting 500 plus HP out of the Twin Turbo 3.0 in the 3000GT would not be too difficult as it already has a large aftermarket following.
The AWD 3000 was a very heavy car, just over 4000 lbs, and in its last year had a top speed over 140 mph and ran mid 13'* in the quarter i think.
