AWD in ITR or ITS?

Duh - the e30 325ix would be interesting...!

There is no way that the 325ix is a better car than the RWD 325i unless it was very wet. It's much heavier and much more complex. Lots of drivetrain loss. I guess you could have a rain car, all set up with AWD and a nice soft suspension. Race the RWD car in the dry and the AWD car in the pouring rain, otherwise, no thanks.

The tradeoff isn't as obvious when the 2WD variant is FWD though, as in the Audis. The early A4 FWD cars had the VW beam axle in the rear too, not the fancier rear suspension in the quattros.
