Abomination.

Why? They are both just automatics.

Not even close. Just because DCT can auto shift doesn't make it the same as an torque converter auto trans.

If BMW felt there was that much of a discernible difference between the two transmissions, they wouldn't of replace the DCT with a ZF8, they obviously didn't..

The opposite of a manual transmission is the whatever automated option they offer.

Yes it does

Also rumors of an M2 GC, according to Autocar. Let's hope that abomination never sees the light of day.

That's pure fiction.

You might be giving BMW too much credit.

In my humble opinion, it's cheaper and easier to deploy a single (auto) transmission across the entire brand. Could they put a revised or new DCT in the M cars? Of course...but it appears they don't want to spend the R&D to make that a reality.

That hasn't been my experience with the ZF, in any guise. It's slower and relatively dim-witted by comparison.

Will the masses like it? Sure. It's smooth - I will give it that...but yes, there is a tangible, tactile aspect of the engagement that has been removed, and that will be missed, by swapping out the DCT.

Just like, to some, the DCT is a step removed from the engagement / experience benefits associated with a manual transmission.

BMW collects $2,900 for each DCT and for some strange reason, DCT fanatics doesn't hesitate to pay that, at all (I wouldn't, on sheer principle).

I sincerely doubt they'll lose much or any profit by replacing it a with a free ZF8, over any R&D cost for the DCT option.

I would say that the shift to ZF8 is writing on the wall that M cars will eventually become hybrid, some time within this next generation.

However, my point was that regardless of how you slice it, if a vehicle doesn't have a clutch pedal, IT IS NOT A MANUAL, The end.

The tactile aspect of a DCT you're referring to is a side effect of a computer controlled clutch. It's not a feature.

If you want 100x the tactile feedback, get a manual. The difference between a DCT and an 8HP is academic.

BMW made a bulk purchase of it that was the biggest in ZF history. This is to save money. Has nothing to do with M except increasing profitability of M cars. Shameful.

BMW knows the average lease guy wants a smooth transmissjon in his $130k car not a bumpy shift. It just happens the ZF8 is much cheaper for them as well.

No shit?



I never said the DCT was a manual - however, I do think it provides an experience that is closer to that of a manual than what the ZF provides. And that, to me, is something one might expect to see in an M car.

I disagree, but that's cool too - that's the beauty of subjective comparisons.

That really wasn't directed at you, it was more of a broad statement on the subject of those that try to justify their choice of gearbox. Just accept what you have and don't try to be what its not. If you like the DCT, say it proudly and call it exactly what it is: an automatic with paddle shifters. Same as a ZF8 and many other automatic transmissions.

And yes, I did own a DCT before, it was a VW R32 with a DSG and it was anemic AF, even with its lighten-fast shifting. Couldn't wait to get rid of it. There is simply no replacement for that third pedal.

Dmboone is right as the decision to do away with DCT is due to cost savings and not because ZF8 is just as good. One less automatic, less cost. Not good for quality of new M cars.

I hope they just drop in the S58 motor, as is, without possibly watering-down any of its mechanical components, for the lower tier/output vehicles, like the G87 M2.

I can't wait to get my hands on one, I feel like the turbo-charged, combustion motor has now plateaued in power output for the RWD & manual platform and this will be one of the last great all-round packages, before they bow-out and only offer all electric vehicles, in their line-up.

As a result, this one will be a keeper

I doubt there will be much a difference mechanically between the S58 in the M2 and M4. Isn't the M2C S55 almost identical to the M4 S55? A simple tune would probably bring it to near parity. The work BMW has done in refining their turbo I6 from N54 > N55 > B58 has been impressive to say the least. I think there's a good chance they'll make at least one more, though.

Yes, the S55 is identical in mechanics, across the model ranges, with the exception of the ancillary water-injection system in the M4 GTS. I'm just a little worried that they might cut corners, but I more than likely have nothing to really be concern about.

Also, they're already in deep talks about hybridizing their fleet, so all-electric M cars are not too far, on the horizon. One would assume..

So this might possible be one of their last full ICE strait 6 motor.. Who knows :

The ZF trans in my X3M40i is better than both DCT cars that I owned before it. Mitsubishi EVOX MR and an Audi S3. DCT trans are loud, clunky, and jerky in low speed situations. And it also didn't seem to shift faster.

Its only the first gear when driving slow, so put it in 2nd!
