Power at the crank? Perhaps to 60 (or so) but not above. The physics says significantly higher losses = you are going to lose and I have never seen any evidence that contradicts this. Show us your "hand".

I tend to agree with you in that the GT-R probably has more total drive train loss than a RS4 (or equivalent) but keep in mind that the losses come from two sources - the number of components times the efficiency of each component (or perhaps more clearly stated the sum of the losses of each component is the total loss). Although a system with an extra shaft will indeed have significantly more components - it could be that the individual components are so good that the loss is not higher.
