You're saying a PDK is better than a transmission that hasn't even been released yet? Maybe we should wait and see if this brand new auto tranny is better or not once it's in the hands of the motoring public...

I'd assumed that it was an E60 V10 but maybe not?

LOL.
Porsche 918: Price: $845,000 plus
P1: Price $ 1,100,000 plus
SLS: $221,000
Read about Mercedes keeping their horrid auto in their cars for the longest time. It was to cope with the massive torque. I also stated that my personal car made 650 WHEEL TORQUE which is conservatively over 700 at the engine, so that statement alone proved that perhaps DCTs can indeed handle torque.
But don't use 1/4 of a million dollar cars and up as examples to make a point!
Those cars leverage all sorts of rare materials to achieve what they do, and I can guarantee servicing those cars can probably buy you a Corvette Stingray over a 3 year ownership...
GM must have seen their 650ft/lbs as a challenge for the DCT from a cost analysis perspective, so decided to evolve the old auto/torque converter to act like a DCT. It will probably be cheaper to own too!
A clutch kit for my M5 is $4800 from Dodson, not including the labor. Not cheap!

Lol this is so true. Bias being the key word. Most people are so stubborn and argumentative that even if it's great but they wanted to dislike it they will find reasons to justify in their head.

Oh ok, so it appears that the stock (DCT? SMG?) trans in the M5/M6 isn't quite up to the task of added power/torque (over stock levels).

For the folks that say a DCT can't handle the torque, I did a little of the heavy lifting for you. Here is an information PDF from Tremec about one of their DCT transmissions, http://www.tremec.com/anexos/File/TR...7%20DCT_A4.pdf
For those that don't want to take the time and click and read, it is rated at 664 lb-ft. So as far as I am concerned, the talk about DCT's not handling Z06 levels of torque is dead to me.

considering the c7 is an all new car, and they new how big dual clutch transmissions were, one has to wonder why they painted themselves in a corner. I am hoping it is because they knew they could make something better and smaller, and they did.

Doesn't matter since the subject of my post was about DCT's in general, not DCT's that can be fitted to a C7. But sooner or later, if the general wants too, a DCT that handle the torque and be designed to fit the C7 could happen. But again, only if the general wants to.
And again i say, the generic topic of DCT's not being able to handle the torque is a dead issue.

I will say I'm impressed with my BMW DCT. It's fast and smooth considering all the stress it's under. I hope GM has created the silver bullet of auto transmissions!

The as-is factory output of 650ft/lbs is already at 98% of the maximum capacity that Tremec unit can handle. Considering the new Z06 is supercharged and has already had a bump in power from 625/635 to 650/650.. is it really that hard to understand that a transmission rated for a MAX of 664ft/lbs of torque is still insufficient.
Not only due you have to worry about the 2% safety margin that you have left. But remember GM is also putting a 5year, 100,000mile warranty on each Z06. And risking their reputation of bulletproof drivetrain equipped performance cars. I dont think any company in the world would be willing to risk that much.. when they already have a solution that is capable of handling up to 768ft/lbs of torque. Meaning the Z06's output of 650ft/lbs is only at 85% of the max rated limit.
