Fasttoys,
If you linked that article here for us, thanks!
If you wrote that article, THANK YOU!!!
Foosh,
I just hope my experience with DCTs are better than yours. I'm looking forward to a different experience in the C8 (assuming I can afford it) than the manuals in my C5 and C7. Hopefully just as enjoyable, but obviously different.
Only 4 more days!
Have a good one,
Mike

Watch some of of the early in car POV footage like the one with Senna at Monaco in the rain. Stuff blows my mine, it looks like the film has been greatly sped up ala Hollywood but it's not, it's the real thing. I get scared just watching the footage, I'd probably cry like a schoolgirl with a skinned knee if I was riding behind in tandem. It's amazing, highly recommend those with an interest that haven't done so consider having a look on Youtube, there is quite a lot of in car footage although less of the older stuff which to me is more interesting.

Oh, and a PDK transmission will be available in a few months for those who really want to chase lap times. The six-speed manual is fun, say the Porsche engineers, but the PDK is fast. No one will confirm it on the record, but it's whispered a PDK-equipped 718 Cayman GT4 has already lapped the Nordschleife seven to eight seconds quicker than the manual car.

Sorry guys, not true. Read the article here. PDK is coming to the GT4 although not initially available.

crabman - my experiences are exactly like yours. Not all TC autos are created the same, and the ZF8 is the best I have ever driven. But even then, each automaker who uses that transmission has variable levels of success tuning it to the car. There is a lot of marketing baloney that GM and others have tried to pass-off about "faster than DCT" but any reasonable person who drives a DCT car vs a TC Auto can immediately tell the difference. The DCT is more direct, more visceral, more responsive and with that, of course, comes a little more raw-feeling that some people don't like. I love it.

Many are hesitant to try a DCT transmission due to Ford’s issues with dual-clutch transmissions in the past. Ford’s PowerShift DCT was seemingly plagued by problems, some caused by a leaky gearbox and some caused by as of yet unnamed sources that weren’t able to be remedied despite numerous transmission swaps and other costly maintenance procedures. These issues eventually led to a class action lawsuit that affected many Focus and Fiesta owners.
It got her through the end of undergrad and through law school driving 90 miles each way every day, so at least it did it's job.
My number one concern with DCT in the C8 "did they get the programing right?" If not, it could blow up in their faces quick.

If you consider pumping a clutch and moving a stick on the floor around less boring than pulling on the paddles to shift the transmission you are missing the fun part of driving and controlling the car. It isn't about how you do the shifting it is about doing it so it makes the car perform better. Zipping around town and doing quick shifts at mid level rpms at less than wide open throttle is not the point.

Ahhh. So you are referring to a car that was in testing but not yet currently available? quote:....

Let me ask you this, when was the last time there was a manual-only Porsche?

I expect there will be a large number of Corvette guys who have only known how TC autos feel, and have never driven or lived with a DCT, that are going to bitch to high heaven about how the DCT in the C8 operates.
Fully expect to see a plethora of bitch threads in here by these guys. And if GM doesn't nail the tuning of this DCT unit - it'll be a veritable shitstorm in here.
That said - I'm one actually looking forward to it (and currently own two manual trans Corvettes), and hope they get it dialed in well.

I any event before too long the car will be in owners hands and the misinformation going to be displaced by the truth: DCTs aren't perfect, they most def have quirks, but they're a better mousetrap for a performance car than an TC automatic despite their limitations. I'd rather have a stick as I said before because this will be strictly a fun car but if I cant then it's DCT all the way. There is a reason Porsche went to PDK almost everywhere but the Cayenne, Porsche owners are a loyal group often owning more than one and once you've had a decent DCT the Tiptronic doesn't look so good anymore.

What makes a manual non boring? Nothing. They all have the same boring non boring attributes. You can shift all of them manually the only difference is if you are moving a stick around or pulling on paddles. Same exercise just different location. TC auto's have two ways to shift manually through a stick on the floor or with the paddles. Who gives a crap when it comes right down to it. The biggest advantage of the DCT is it doesn't have a torque converter. It isn't a slush box. It's biggest weakness is it doesn't a have torque converter so it doesn't get the extra gear ratio that a torque converter provides. If you aren't doing an initial high acceleration launch, slowing inching into a space or pulling a heavy load you don't need the torque converter. Except for those conditions either the DCT or manual transmission will do the job better. If you need fast positive up and down shifts then the DCT out performs the manual box unless you have one of the few automated manuals which does the shifting and clutch application for you if you want it to.
If you consider pumping a clutch and moving a stick on the floor around less boring than pulling on the paddles to shift the transmission you are missing the fun part of driving and controlling the car. It isn't about how you do the shifting it is about doing it so it makes the car perform better.

You can argue objective criteria until you are blue in the face, but personal preference drives perception, and perception is the reality for any given individual. You can't define for other people what part of driving and controlling a car makes it most enjoyable.
There are people like me who have considerable experience with both, and no matter how hard I try, I can't enjoy paddles as much as I enjoy using a clutch pedal and manual shifter.
The objective criteria are often meaningless in terms of what makes a more enjoyable driving experience for any given individual.

Then leave the track and start driving around town. Sure, some prefer autos in that case and yes, that is what a DCT can do, some of them well, some... not so well. Me, if I am not in my truck, I'd prefer to drive a manual. The one vehicle I own that has paddles (granted, it's an auto with paddles, but the point I am about to make applies), I've used the paddles maybe 5 times in 2 years in driving around town. IF I buy a car with DCT, I'm sure it will be the same. I drove a friend's M3 with SMG around for 4 months, don't think I really ever used the paddles in normal driving. When I drove his M3 with DCT for a few weeks, same story. And while both cars were faster than my M3 with a regular old manual, I preferred driving my car.
Back at the track, coming into turn 12 at COTA and having to downshift from 5th to 2nd (hitting each gear along the way, not skipping) is just a total blast, I really don't want to lose that.

Funny enough, your last paragraph kinda proves the point about manuals. I'm sure you are aware of what happens with a manual transmission when you come into a corner at the track that requires a downshift. Yeah, with the synchronizers in there, you don't need to double clutch, and if you get it done quick enough you might not need to rev-match. But, it is highly likely you are going to cause the rear to lock up a little (or a lot) and that destabilizes the car if you don't rev-match. The problem for some of us with things like DCT/SMG and even the auto rev-match is it takes that "fun of driving" part completely out of it and let's face it, you aren't really "controlling the car" because the computer is controlling part of it for you. Finger flip or not to downshift, the computer will decide if your downshift is appropriate (ie, no over-rev) and execute all of the steps to do it. That's not how I would defining "controlling the car".

The irony of the above is that 99% of these cars will never see a track. Yes, in a track car, give me the DCT. In my fun street car, I want a manual, and flipping paddles is no substitute for the enjoyment I get out of it.
However, I will add that auto rev-match has significantly minimized the too-busy part on a race track. I felt much less stressed driving the C7 M7 on a track than I did in my C6 Z06.

"Back in my days, I had to walk to school in 10 feet of snow bare feet to go to school"
This is what this thread is turning into. I never see a group of individuals so resistant to change. Cars are getting to the point where they need all the nannies in order to keep on the car on the road/track. For every owner who knows what they are doing, there is a thousand who has no clue. To expect "The casual" to comply to your ideal of what a "real driver" should be is ridiculous. DCT is a positive change for the vehicle. I don't know how anyone would see this has a negative. This is coming form a M7 owner. I am not ashamed to say that I use the Rev Match option all the time. It's not that I don't know how to do it, it just more convenient to let the care do it.
If I buy a C8, I won't care if it has a DCT. I will embrace that change because I know that transmission is going to be faster and more efficient that I could ever be with a shift stick and 3 pedals. The stigma that Corvette is an old man car is not something that is going to go away with thread like this. It only amplifies that the car requires a "rejuvenation" because soon all the current Corvette owner will be dead there will be nobody left to buy the car.

That is not the fun part he is addressing. Controlling the car is a lot more than simply shifting a manual. I understand the fun part of complete interaction with the car. There are times that can be great when perfectly matching brake, shift, turn and track out. But, there are other times that a turn really gets too busy and eliminating as much as one can is very desirable.
But my point, you can't say "controlling the car" when the computer is controlling an important aspect of it (gear selection). And I gave an example of that "too busy" turn.... it's still more enjoyable. Turn 15 is another. Coming into turn 4 at COTA, hauling ***, lots of transition in direction, still need to brake and downshift or carry a long gear through 5 and likely 6. I've done them in DCTs, some of the best, still more fun and I felt more "in control" of what the car was doing with a manual.

If I am racing, like real racing (wheel to wheel or time trial), then yes the DCT is the way to go. HPDE? Nah, I'm not racing anyone and I'm just practicing all of the skills, which I include shifting a manual as part of that. I wish my actual race car could be a DCT, but it is banned by the rules.
