Not to get in the middle of your lovers quarrel, but we already have a blower on a C7, so he wouldn't be first at that.
Carry on.

How about the 458 Italia? How about the McLaren MP4-12C, or the 911, or the SLS AMG, or the California, etc etc etc that all use dual clutch systems... Are these all "not performance cars?"
How about the track only (NON-STREET CAR) McLaren 12C GT Sprint car that uses a dual clutch?
You are correct about racecars not using DCT at the higher levels (because they are illegal and the durability of the dog clutch sequentials) However they are being used more and more at the club levels and more and more are preferring DCT in SCCA.
Proper tuning of the DCT is the main concern, reliability goes hand in hand with this.
He doesn't want to have to think that much into it. Assume all of those things will be right on (I seriously want to trust whoever designs the car to be that good - no errors in gear ratio choice). He just wants the benefits of a DCT. If the gearing isn't right, of course no one will like it. That should just be a given. Make a DCT, gear it correctly, make it where it's no more hassle than most (I know there are extra services, etc), make it handle a lot of torque, and make it less than $10k as an option. We want it all. Go.
Fun part? I'm serious.

DCT is not necessary. Give us a very fast automatic like the Aisin transmission which has shift times as fast as Porsches PDK. With Corvettes wide torque band a DCT is just a waste. Here is a transmission that is just as fast as a PDK.

It is an amazing transmission. I will soon buy a a C7, but am waiting to see if GM offers the 8 spd auto in the C7 2015. If not, will go with the C7 with the A6.

LOL ok... M cars are not performance cars? And who said anything about them being race cars? (Besides the variant used in ALMS, and yes i know they have a semi-auto sequential) Yes they are street cars just like the vette, and yes they ARE performance cars...I am taken aback as to how you could possibly say they are not performance cars...
I've also driven a 911 and a GTR shortly. Those are cars that I can get behind having a DCT. They are both in excess of 100k new.

Traded my 1999 C5 for a 2005 C6 with the A4. Traded the C6 for the Lexus ISF with the 8 spd auto. Locks the torque converter in all but 1st. Must get out of 1st in a hurry as the ISF lights up the Michelins all the way to 2nd & beyond.

I've read nothing but great reviews on this Aisin AA80E transmission. Maybe the DCT fanboys will actually read up about this alternative concept. Tadge has explained the issues of a DCT numerous times now. You would think the DCT fanboys would read, concentrate, and listen.

Rumor has it that either an 8 spd ZF sourced ( german tranny maker) auto and /or a DCT is on the horizon. Likely GM will do what they did when the C6 was introduced. The first year of the C6, 2005, had the holdover A4 tranny used in the C5. The second year of production of the C6, they introduced the A6, which was a POS when operated in manual mode with the paddles. Ask me how I know( it has been dramatically improved starting in 08 with the best version in the C7). One thing GM knows, is most vette junkies are like the proverbial donkey in pursuit of the carrot. All GM has to do, is bring on carefully calculated enhancements, or better yet just make a few cosmetic changes and the faithful will beg borrow and steal to buy a new vette. Again, ask me how I know. As an example, if GM comes out with an 8 spd auto/ 7 spd DCT in 2015, tons of guys who bought 2014 C7/A6's will replace them with 2015 C7's with the new auto tranny. IE, the donkey after the carrot.
A modern tranny is a necessity to keep the vette ( and CTS-V,ATS-V,etc) relevant with BMW and Porsche, so expect to hear about one, either at the Detroit auto show in January or the bash in April when the 2015 models are revealed.

How can I say this? Well, because one time, I actually drove a 2012 M3 with a DCT for about a month while the owner was away. If that's a "performance" car, then my mother's X5 could be called a "sports" SUV.
I've also driven a 911 and a GTR shortly. Those are cars that I can get behind having a DCT. They are both in excess of 100k new.

What does 100k price of a car have to do with a thing we are discussing? And comparing an M3 to an X5?! Lol GTFO dude

Tadge is the current chief engineer for Corvette. He is also the head cheerleader who spews BS excuses for why C7 didn't launch with a DCT. Any educated Corvette owner like myself sees through the PR spin and lies and is refusing to buy another new Corvette until GM gives us the OPTION of a modern DCT. Every educated car person and manufacturer isn't wrong about DCT. GM is the one who is wrong and needs to offer a DCT for 2015 or ASAP.

New RWD Cadillac's for 2014 at least will get AISIN eight-speed automatics in the TL-80SN, per a short-term agreement between GM and AISIN. The heavy-duty variant TR-80SD in my TDI Touareg is one of the best things about the entire vehicle, it's a very stout transmission.
It was rumored that the new C7 auto would be AISIN and it probably should have been per this agreement between GM and AISIN, but we'll have to see how far GM gets with their own eight speed autos before MY 2015 to see if GM will resort to a Japanese transmission in their Corvette, (which is probably exactly why they didn't port it over into the C7.)
If anything, I'm disappointed that GM didn't take the up-rated 6L90 from the Camaro ZL1 and use it for the C7 as it's 6L80 isn't able to absorb as much torque, and as we all are learning, the new LT1 is a very high-torque engine.

I'm somewhat new to the corvette platform as a whole (minus knowledge on the LT/LS engines alone) so excuse my ignorance to who Tadge is, or what he said or didn't say, but I do know what other professionals across the auto industry have said in regards to the DCT, as well as seen the advantages first hand like many of you.

Corvette has never been a "money is no object" marque. If you want a DCT go buy one of the brands you listed and move along. I believe the DCT is a 10k option on the audi, putting the base model at what, 125 grand?
