In this country, unless you are taking it to a track, the operating speed is 0-80 or so. Once you pull second or third, you're right, 400 to the rear wheels, or even 500 is fine - and that's on near perfect pavement on a dry day. But while you're in first, this is just too much power and is pissed away by torque management (human or computer). Throw in our awful roads, etc and even 500 in second has to be limited. We don't have an autobahn - there's no public place to rocket to 150. That's why AWD is so key, it allows full torque to the wheels in first and second gear. That's where most Americans are going to get the thrill and use the power. Further, a touch of water, or a ripple in the pavement doesn't mess anything up. Forget the benefits in real weather where RWD just doesn't compare in any meaningful way (and you know that). Also, making the tires any larger adversely affects performance in weather. Also hurts fuel economy.
I'm surprised that Germany leads us in technology that is more applicable here, than there!
