Patent for Dual Clutch Transmission filed!

Out of curiosity, why can a DCT not have a clutch pedal that disengages both clutches at the same time and overrides the computer.
There may be times you want to "feather" the clutch to get over ramp bumps etc. without the computer providing all or nothing.

Since Porsche has offered the PDK(DCT) sales are at 75%. Not even the best drivers can shift as fast and efficiently as the PDK. With the sport chrono option with launch control the 911S with only 400hp outperforms the C7 with Z51 in the 0 to 60.
Just imagine what the C7 will do with DCT. The option is 4050 in a Porsche. That gives you full auto and manual paddle shifters. However I would not hold your breath for this option. If GM just filed for the patent, it might be two or three years before you see it in a Corvette. In the next five to ten years the manual trans will go the way of the dodo bird. Ferrari no longer offers MT and Porsche offers only the PDK trans on the upcoming 911 GT3.

I agree and have mentioned this before. F1 cars have a 3rd paddle behind the wheel. Although primarily for launches, a third peddle/paddle permits relaxed operation for situations as you described. I can't envision GM doing it though. Handing control back to the driver doesn't seem in their DNA, probably for some possible liability concern. When the manuals are gone, it's probably as final as it is inevitable. But you pointed out the key differentiator, manual clutch control which does not exist currently in any production DCT automobile. I suspect the rev matching feature of the C7 is as close as we'll see, which is frankly a highly effective equalizer for a driver not practiced in the heel/toe technique.

Based on the article on the CF main page, it seems this may replace the automatic trans on upcoming models. I think that would be a mistake, unless they kept a traditional automatic mode. There's a lot of people who simply don't want to change gears on their own at all. Likewise, I hope this doesn't replace the manual transmission, as it has on so many other sports and exotic cars.
Hopefully this will be a transmission used as an option on the Z07 for those who are looking for maximum performance, yet I feel like it will become the only transmission by the time the next generation debuts.

I think if GM really did it, put the 7 speed DC on the Vette in the near future that'll look bad for them. Remember Jeep with the Grand Cherokee SRT-8, that was really crappy.

I do believe that this transmission will eventually show up in the Corvette. Dual clutch transmissions are designed and intended specifically for people who want to shift for themselves (enthusiasts).
Having said that, the only reason it might not make it to the Vette would be because of HP/torque limitations, but I can't imagine a world where GM would develop this transmission and not be 100% certain that it was going in the Corvette, their flagship sports car.
To make a long story epic, yes, I firmly believe this is going in the Vette eventually. Near future? that's another story... I'd say 2016-ish.

The new GT3 PDK transmission does this, but without the clutch pedal. You simply pull both paddles in at the same time, and it opens both clutches. You can gas it and release the clutch if you want. Porsche calls it their "burnout" mode.

I'm saying that sometimes you want only a half clutch just to get up over some bump like a small curb,ramp, speedbump. An auto will slip the torque convert. to do this

Say what you want about Porsche. They may be overpriced and underpowered. But their technology is definitely leading edge. I'd guess this is the only DCT on the consumer market that does this.

Go drive a modded GTR or PDK 911 and then tell me those cars aren't a freaking blast?
Go watch some roadcourse vids of either and tell me there isn't driver involvement.
Does it take away skill? Of course it does, but I don't drive to say "Ahhhh, I have better shifting skills and heel to toe technique then you ha ha" those cars are fun as hell to drive.
I love manual too and loathe automatics like all of the ones that get swapped into modded Vettes. If you drive them you will see a DCT is nothing like slushbox when in manual mode.
