It make no sence to bring the new M5 with an Auto and with the M-DKG ... and people who had seen the real productin-car quoted, that this has the ZF 8-gear Automatic ... and also remenber the interview with an M official not long ago, were he praises the ZF8 and how sporty it was ... but:

Thanks Uli, I did not know that prototypes were definitely built with DKG (DCT for us in NA...).

As we have been discussing, here and in other threads, modern automatic transmissions have come a very long way. 7-8 gears, wet clutches that bypass torque converters and offer full lock up, high rpm capability beyond the limits of a torque converter, full DCT style user controls and software adjustability - all while maintaining the ultra smooth take off and power brake capabilitties of a traditional automatic!
If the transmission feels like a DKG and performs like a DKG (shift speeds and efficiency), in my opinion, I would have no objection to such a transmission in a sports car of mine, M3 or otherwise. It will be VERY interesting to see how a true modern automatic would be named and marketed in the M3. There is simply too much stigma associated with automatics. That brings the discussion right back to the jargon discussion we got side tracked with right here!
I have not sampled it personally, but from what I have read the automatic ZF transmissions in the XK and XF are about the best out there and feel awfully close to a DCT.
