Yes the shape of the torque curve matters but ultimately in a WOT type of competition if the car never sees below X rpm (on a normal S65 that is about 6000 rpm, less for just a split second during launch) then the torque at all rpm below that rpm X are utterly inconsequential. Peak hp is always the single most important factor. Although "area under the curve" (physically meaningless - what you really mean is time averaged power or torque - not rpm averaged) is important, I wouldn't at all bet that a 100 hp peak wheel power advantage wouldn't entirely trump the "area under the curve". I'd be happy to run a simulation if you provide two examples of the torque curves in 500 rpm increments for representative examples, one at 600 peak whp and one at 700 peak whp.
