David FritzingerYou're absolutely correct: race and rally drivers want to be able to use both the brakes and the throttle in order to steer the car, and RWD offers a better layout for doing that.

So yes I meant understeer in the drivetrain layout context. Though subaru with it's outgoing symmetrican layout is notoriously unwilling to rotate. I guess it's a moot point in a pig such as Q7.
It won't be as bad as it would be in a RWD car, because the fact that the engine braking operates on the front wheels rather than the rear means that the reduction in traction operates against the oversteer rather than adding to it.
I think that some drivers (race and rally drivers come to mind) actually want oversteer, and prefer rwd to fwd because the oversteer is more controllable and is induced accelerating through a turn gives you more speed coming out of the turn. I believe that in Porsche 911s (until recently), and especially in 911 Turbos, the only way to safely drive the car on a twisty road was to enter the corner relatively slowly, and accelerate hard on the way out. Any other technique would put you in the bushes, backwards. That the modern 911s handle so well is an excellent example of engineering over physics.
