Of all those cars, the slush box 135i was the quickest from a dig up to around 80 mph. There was really something beautiful the way the torque converter meshed with the turbos and the torque produced by the N54. The car hooked up great and it never felt like any boost was lost between shifts. The only downside (other than the level of driver engagement offered up by a M/T) was the relative ease by which you could overheat the transmission, rendering it useless. The e92 M3 is not a torque monster and DCT seems to compliment the high revving S65. The M6 on the other hand has gobs of torque, but is quite possibly the slowest car off the line.

I see your point, but remember M was never built as a dragster;straight line is only part of the performance. In my opinion, instead of making m5 have more power it is better to lose the weight of the car with DCT tranny (they can do so with carbon fiber roof and aluminum body parts.)
If you want luxury, you really should be going for 550i instead. (At least thats what set M5 apart! Sportiness over luxury)
