Porsche Doppelkupplu
Totally off 993 topic, but what do people think about the Porsche Doppelkupplu transmission?
I've been a manual guy for decades, but is this as good as it sounds?
Um, to keep this sort of on topic...my 993 does NOT need a clutch.....

I have driven a VW GTI with their version of the transmission and ridden in a 991 C4S with it. I was seriously in doubt when I started both rides but afterwards no doubt. It is simply the finest transmission ever made. Both cars just seemed to keep accelerating with completely unperceivable shifts.

it is really good.
the 991 turbo and 991 GT3 are no longer available with manual which says something.
PDK is faster on the track and makes for nice daily driving bumper to bumper traffic.

PDK (Kupplung is the K) is a great transmission if you're into that sort of thing. I'm not, so I don't care how good it is.

Gearing
Gearing for PDK vs Manual transmission is different.

Of course, the guff from the 993 forum folks might be unbearable.

I had an Audi with that and I really didn't care for it. It may have something to do with the engine cal but to me it feels like a 200k transmission with worn gears and clutch, so you can just do clutchless shifts all the time. Maybe the ones on porsche will feel more direct. Then there is the issue of changing gear via two micro switches with the pedal feel purely designed to emulate something mechanical. It's just a little too superficial to me.
Porsche is more or less forced to do PDK on the GT3 and TT, because they will always be bench marked against their competitors for the all important 0 to 60 time. There is just no way to get a good time without a double clutch these days. The additional sale, if any, of offering a manual option does not justify the cost of homologation and the hit on average fuel economy. Not to mention that a lot of cars these days are sold to the new markets, e.g. China, India, Middle East, where people don't care for sticks. It really is just as much about marketing as engineering.
