My question is would you consider DCT a manual or automatic transmission when filling out an insurance form. I'm going to get DCT because I don't want to have commute daily 30 miles with a manual transmission in traffic.

I had the SMG transmission on my former m3 (e46) much the same as the DCT only that the DCT is an improvement over the SMG. Some of my former cars were MT and I sort of missed it so I went back to the MT. In retrospect my next one will be again a DCT or whatever BMW will have at the time Have fun with whatever you will get in the end ...

I have owned both DCT and the 6MT...Both are amazing, its all about "whatever floats your boat." I loved them both equally for different reasons and to be honest I would be just as happy with either one. However, I dont have to commute to work in heavy traffic, if I did I would choose the DCT without question.
Oh and I have 5 pins in my left foot so the DCT is a little easier on me for prolonged drives Last edited by Raptor251; 09-24-2011 at 10:54 AM.. |

I have ordered DCT. It will be my first autocar. I am really worried that I will not like it but I want to try it and I think it helps selling later. I only want to have the car for 1 year.

As to your second statement, your point is well taken. Interestingly, at least to me, is this little nugget about the benefits of a manual over anything without a third pedal. Quote:

From a pure performance standpoint, we have arrived at the time where the automatic can outperform the manual. It didn't used to be this way. The reasons for buying a manual now are different.

Someone else asked this in an earlier thread, and the consensus was that automatic should be chosen. Insurance uses that mostly to gauge the possible cost of repairs and DCT just like a traditional auto would be more expensive to repair than stick. Plus any insurance adjuster would probably just look in the footwell, only see two pedals, and say "It's an automatic". If you pointed to the paddle shifters as a manual mode, he would correctly say that lots of automatic transmissions allow that, and if you then tried to explain 2 clutches vs a slushbox, he'd probably give you a blank stare.

The Dual-Clutch Transmissions Goes Down In Front Of The 8-speed Gear Box The German automotive manufacturer ZF announced that BMW might give up in favor of dual-clutch transmissions automatic transmission with eight steps. The same measure could be taken also by Porsche regarding PDK transmission. The double-clutch transmissions from BMW could be replaced with eight-speed gear automatic transmission boxes. This situation was basically launched from the ZF company sources, the DCT transmission supplier for BMW and PDK for Porsche. It seems that the two types of gearboxes are niche products, which are extremely expensive to manufacture and have limited utility in the range of the two manufacturers. It seems that the existing materials and technologies do not support a higher torque. The most prominent argument of the hypothesis that the DCT transmission will disappear from the range of BMW M models lies in equipping the X5 M and X6 M. The two SUVs are equipped with a performing automatic transmission to provide updated technical changes of speed as fast as with a dual-clutch units. Eliminating the DCT Series M transmission from the Bavarian manufacturer could lead to a ceasing production of this type of transmission line and its replacement with an eight-speed automatic gearbox, which already has been created by ZF engineers. The BMW 760i BMW F01 is the first BMW model that will use this type of transmission. While some manufacturers still offer automatic transmissions with four or five-speed, ZF people in Detroit had an automatic gearbox with nine steps, destined to the cars with front wheel drive and transverse engine. The experts from ZF presented a new automatic transmission. In addition to the record number of gears, nine, the new unit is for use on cars with transverse engines. This means that the nine-speed ZF transmission will be implemented on a front-wheel drive model. According to first information, the new transmission will debut on a Chrysler model, but there are good chances for it to go further on BMW models with front wheel drive and in other manufacturers ranges. Thanks to how to change module took over from the eight-speed transmission made for models with engine located longitudinally, the changes will be extremely fast speed and will not be felt by the driver or passenger.[/SIZE][/FONT]

However, can you begin to imagine the exhaust note of those 8 or 9 close gear ratio equipped vehicles that are shifiting within an relatively narrow rpm bandwith at an also relatively modest 6k or 7k rpm for an upper limit?

I believe that article predates the announcement that the F10 M5 would be using the 7DCT and not the 8AMT, even as many sources claimed the ZF DCT would not be able to cope with the torque from the S63.

This is reason enough to doubt the rest of the article. See also: http://www.dctfacts.com/archive/2009...trags-dct.aspx I don't know about the m5 but I suspect getrag provides that too. |

I heard ZF engineers speak at a presentation and they said that they expected that future versions of "traditonal" planetary gear automatic transmissions would rival and perhaps match the peformance of DCTs. They also felt that a torque converter is a very good device for smooth starts and as long as they get locked up at low speeds they have negligable effect on performance and efficiency. CA

I opted for a manual (..as I always have; the only automatic that I've ever owned is the one and ONLY car that my mother purchased for me in high school), and I'll continue to opt for a manual regardless of the slight performance variance with regards to shift speed. There simply is no replacement for rowing the cogs IMHO.
I still think that the DCT technology is impressive however. |

Good catch. Yes, all BMW DCTs are Getrag. Porsche uses ZF.

I think that the appeal of the DCT is two fold. Part of the appeal is the technology and the fast shift times and part of the appeal is the idea that it is "not really an Automatic Transmission" and does not have the stigma of being a "Slushbox". CA

Anyone of you haver the lap times for the M-DCT to compare to the MT posted here?
