No wonder you can't, it's generally classified information. This is from US patent registered in 2003. Download the PDF and you will notice that they don't specify on the published paper but instead say "FIGS. 14 through 18 torque curves of embodiments in accordance with the invention on the shifting time between two gears," Other than the patent one, about a decade ago Volkswagen AG published an article on DSG but it never specified shift time. I believe they suggested an "average shift time under full throttle" to be 8ms in DSG transmissions, you can google "dsg 8ms" and it will give you bunch of old articles. ZF8HP on the other hand is known to have 200ms~250ms as default setting, although it is known to take half the time thanks to optimization of shifting programs (by individual makers such as BMW, Audi), bringing down to about 100ms. Haven't got the info on 8 speed DCT from ZF since it is new. http://papers.sae.org/2012-01-0060/ I haven't got an access to this article yet since I am at home, but I will also post what I can find. I believe it could contain actual values in this paper.

BMW already mentioned it wouldn't use American transmissions for its shift quality(shift time and smoothness) albeit its high torque limit advantage. Why would they cross the Ocean deliberately when they have excellent makers such as Getrag and ZF already in Europe?

Are you sure that the 6-8 ms shift time of the Porsche DCT is not the time it takes to change the gear ratio only? IE, it's not taking into account the time it takes to disengage, then reengage the clutch?

In three years, BMW will announce " no one uses the flappy paddles anymore because our 11 speed automatic is so good " and they won't include them on cars anymore , saving another $X per vehicle in manufacturing costs . |

I've noticed the seats have a black strip going down the center. Also the lumbar support slightly indented in the center. Can't wait to get this thing. However the exhaust note as this thing is driving is almost non existent. But then again we are getting the exhaust button so mayb there is still good to come

Is this really the kind of interior people want these days? Super fussy with all kinds of hideous glossy material everywhere and WTF is going on with the gear selector??

Also, considering this is an automatic only car, I'm I the only one who think putting a fake gear lever is a waste of console space ? I means it does not have any mechanical linkage, it would be a massive advantage to just replace it by a button or a stalk ? You'd get twice the amount of storage space.

Auto bmws have had paddle shifters for almost a decade now.

Could be, but since the number is compared with other DCT equivalents, they are likely measuring time of o the identical mechanical process. Getrag isn't the fastest shifting DCT I've seen; I imagine it is due to some reliability compromise that comes with higher shifting speed.

I was thinking the exact same thing - I had to rewind the video to see if I had issued the "startup sound"
