Audiholic, sometimes I feel that you have massively unrealistic expectations!
The car is fabulous, albeit it a tad on the obscene side (to quote a friend of mine).
650 Nm, eh? No way you're going to get an S-Tronic transmission to handle that torque unless you pluck the (very different) dual clutch transmission from the Veyron. Sequential manual? You'll fry that clutch with all that torque being available at just 1500 rpm. 6 speed manual gearbox some of you ask? You'll need a left leg that's built like Ben Johnson's and be taking all those "supplements" too. No, I'm perfectly comfortable with a good old-fashioned, robust torque convertor automatic. It's only on a racetrack pushing at 10/10ths that you'll need quicker shifts and besides if it's anything as good as BMW's Steptronic in the 335i (and I'm more than certain it will be) then it'll be darn well suited to the big wagon.
