It's OK, I welcome constructive criticism but not so fast on this count.

First of all, to clear up any miscommunication, I said for the track the M-DCT is "almost certainly better". Since no one has independently tested M-DCT I guess we'll have to wait and see before I remove the almost qualifier.

However, for a dual purpose car I'm not sure the distinction is so cut and dried.

I don't know why ZF would develop, and manufacturers would spec, both the new autos and DCT in high HP, performance cars if 1 was always superior to the other. I also don't know why Audi would spec the ZF 6 speed for its R8 V12 TDI concept if the DSG was always better. And for that matter the new RS6 speced with the ZF. Ditto the new CTS-V which used to be manual only. I also don't know ultimately if autos developed into manuals will be less than manuals developed in autos.

I do know that shift times can be measured differently. The GT-R's DCT is claiming R mode shift times of 200 ms, which caused an outcry on GT-R forums and threads of 'Why so slow in comparison to others?" until it was discovered that the shift times are measured differently, and really the GT-R uses an updated B-W core the same as other DCT's such as Audi's DSG.

I'm not sorry that I keep an open mind on these things.
