I ordered my '14 C7 A6 today. I'm a "cruiser" not a racer. Sure the romance of the next best thing helps sell the next production year but after renting a C7 for a day....an A6 with all it's current refinements is good enough for me!!!

After having issues with pretty much every GM automatic transmission (i.e. 700R4, 4L60E, etc) I have ever owned, I ordered my new C7 with a manual transmission. There are exceptions, but for the most part, my experience my has that GM auto trannys don't hold up well over time.

I hope we both don't have any issues, but a clutch is alot cheaper than a transmission.

Sure, when everyone is raving next year about how much better the A8 is it might make me think, but unless I am seeing huge differences in 1/4 mile times, I won't care.

Why is it that every thread regarding the new A8 transmission for the 2015 C7 has the ongoing theme that makes the assumption that GMs A8 is inferior to the DCT. None of this has yet to be demonstrated. Have the DCT fist pounders considered the possibility that the C7s A8 may actually be superior to the almighty Porsche DCT?

I can speak from personal experience. Regardless of what each transmission cost, there is NO COMPARISON between the A6 in my C7 and the DCT in my previous car (2009 Z4 35i). The DCT is far superior. This was NO surprise to me. Life is full of compromises and there is no such thing as a perfect car.
It remains to be seen how much of the HUGE gap between the Automatic and the DCT GM filled with the A8, which still uses different technology than that in the DCT/PDK.

The Porsche (PDK) or BMW (DCT) isn't better simply because it is a more expensive option than the C7's Automatic Transmission.

But what does that mean exactly?
It completes the shift faster when you press the paddle or once it receives the command from the controller it shifts faster? Big difference there.
No one is pounding fists, the A8 just isnt a huge leap in technology from the present A6 - or any other modern 8 speed auto. Its going to end up in way more pickup trucks than in Corvettes. I'm not a hater, I welcome any new technology, and of course GMs job is to sell new cars so they will say whatever to sell them and create a buzz. Until they are out there no one will know how good the A8 will be in the C7.

Apparently the new A8 is 6 pounds lighter than the A6 it replaces. The article I read when the Z06 was introduced was quite impressive. I really hope it lives up the the hype and revolutionizes how people think of a torque-converter based auto. If it doesn't... all the DCT fanboys will be on here screaming "WE TOLD YOU SO!".

I said it remains to be seen if the A8 will close the gap on the DCT. No assumptions.
