Isn't max torque for these cars around 5500 rpm for the competition and 6,100 rpm for base model? So if you exceed this on your way to red line which is 7,200 rpm, should you not experience a decrease in torque?

Those hard shifts in the DCT were more for show than anything else. At the limits the smoother shifts of the ZF will keep the car more composed. The DCT was more engaging and gave the cars some additional personality, but for the majority of auto transmission buyers the ZF is the better choice. In daily traffic and around town it is much smoother and more comfortable.
There is a noticeable lag when shifting the ZF manually vs the DCT. It is not that the shifts are slow, it is a gap from pulling the shift paddle and the ZF actually shifting. Your brain adapts to it pretty quickly, but it is definitely there. I am not saying either is right or wrong, I have owned M cars with both setups and they each have their pluses and minuses. |

ZF (and other planetary autos) have to do this by function of their design. Their clutches can't slam gears like DCT clutches can, so there's some level of slip and/or torque reduction that is needed. Not dissimilar to letting off the gas when clutching in at WOT in a manual vs a DCT which is powershifting

The AT transmissions may be a bit of a disappointment in some respects versus DCT, but boy have AT transmissions come a loooooooong way. And, again, for the target audience, I think most will actually prefer the AT to the DCT because they will be willing to accept a bit less engagement for reduced NVH. An AT also seems more of a fit for a car of this size. The cars size would probably be my biggest complaint. That said, it is probably appropriately sized for the target market - and there is the M2 for folks like me that want something a bit smaller. I'm also not a fan of more weight but BMW seems to have done a masterful job of minimizing impact. |

just drove the G80 M3 today and last week drove the M4 MT
I have an M3CS which I drove to dealer I loved the G80 to me the ZF transmission is very good yes the DCT feels snappier , but overall the G80 is a better car |

Personally I don’t love the M-DCT and I don’t despise the modern ATs. I like both of different reasons. So my comment on passing on the car was for those who have driven it and feel like the OP that it’s a major downgrade. I don’t think that feeling will disappear cause they really do feel different. It never did for me vs MT as long as I despised AT. Everytime I drove an AT I couldn’t wait to get back into an MT, the AT totally removed me from the driving experience, feel of the car and precise control. Not anymore with modern ATs, they are more than acceptable. That said I will go AT this time and I will miss the MT but not a DCT. Last edited by solstice; 03-19-2021 at 09:11 PM.. |

Maybe it's just the way BMW manuals feel, but I really didn't like the manual in the G82 I test drove. The throw was long and mushy and the clutch had basically no feel - I kept making jerky shifts even with the rev matching on because I couldn't feel the bite point start to engage and kept the clutch slipping too long. I'm sure I would get used to it and it would be fine after a few days, but it was more distracting than engaging. Glad I'm going with the competition.

It will be interesting to compare the ZF8 and PDK. Though I understand that PDK is not offered in the electric porsches like the cross turismo. If that's the case, ZF8 may be the eventual winner in the transmission stakes. For now though, I much prefer the DCT in my F87 CS to the ZF8 in my G02 M40i.

Even though the G8x is new so aftermarket tuners have not had much time with the car yet, but shouldn't transmission software updates address many of the concerns being mentioned regarding the AT? I don't own an F80 DCT car (I have a F80 6MT), but from what I have read on the forums, transmission software upgrades on the F8x DCT cars did improve performance. So if the AT concerns people are mentioning now resonate loud enough, maybe BMW will tweak the transmission software for the M-Cars to help get back some of that DCT like feel/performance. And of course there always is the aftermarket AT tuning options once available.

Test drove the G80 M3 today, ZF still a HUGE let down, came away from the test drive incredibly conflicted. Love the way the car drives, the power for a 6cyl is good, interior/tech are great, steering is the best electric BMW has done to date. Get back in my F10 and just wonder if we just paired this transmission in that car we really would have had something.
I've bemoaned on these forums for years about transmissions and really thought I'd eat my words one of these days and get the ZF in either the F90 or the G80 but just don't think I can do it. Should probably just drive a 6MT and decide from there. |

I couldn't agree more about the ZF replacing the DTC. Its the only negative thing I have to say about the cars performance. But the ZF is pretty much bullet proof. I do think they didn't a better job tuning the AT for the G80 then then they did for F90 comp.

I largely agree with this. Having driven the G80 for a week now, I definitely miss the DCT. I generally drove in "manual" mode with the DCT because I love a MT, but hate having to deal with a clutch in city traffic. I found the DCT to be a very good compromise on control of the shift. That said, in the G80, I have been more frequently driving it as a regular automatic. I find the self shifting a bit jerky compared to the DCT - that might just be adjusting to the feel of the car and the sound of the engine which is very different from the F80. However, I also find this AT much better than the AT in the F80. I never really liked the F80 DCT in auto mode. The G80 seems more responsive in the auto mode and also seems to more aggressively downshift than the F80 did. |

It's only a matter of time before XHP releases a flash for the G80/82 comps. $300 tune drastically changes the shifting characteristics of my M235i. You can make shift speeds much faster and brutal if you want along with tons of other customizations.
