Porsche doesn't even share that transmission within VAG. Audi, for example, just stuck the ZF 8-speed in the new RS5 "because a DCT couldn't handle the torque". We know that's not true, since the same engine (and more powerful ones) have DCT's in Porsche models. And in BMW models, for that matter. As for why BMW's existing DCT wasn't used, I imagine it wasn't designed for AWD, and if Audi didn't get access to the DCT, BMW sure wouldn't. My understanding is they got the shift times in the new M ZF down to 100ms. If so that's as fast as the best DCT's on the market, and better than any competitors (most of which are at 200ms). BMW is already known for having the best programming of the ZF, I'll wait to experience the new M5 before assuming they suddenly forgot what they were doing when it came to transmission logic on this version.
