If the M5 pulls away "at speed", whatever that is, it will be because of a horsepower advantage, not a torque advantage. I'm tired of the "old school" "torque wins races", "no substitute for cubic inches" nonsense. Torque is meaningless once your are "at speed". The extra torque of the M5 will translate in to more horsepower at lower RPMs than the M3, very useful for autocrossing or around town if you don't want to downshift, but meaningless once the engine is near its power peak. A Formula 1 car makes less torque and probably has more aerodynamic drag than the M5, but since it revs to some 18000 RPM it can make about 800 HP, do you think the M5's torque curve will allow it to pull away from Mika and Michael "at speed"? I didn't think so.
