I love/hate you PDK! But now I'm free...

Synchromesh is for lazy drivers who don't get involved and can't double clutch <snicker>

In fact, F1 cars still have a manual clutch, but is used for different purposes due to F1 rules. Frankly, I think the F1 drivers would love to have a 'traditional clutch' inside the cockpit, because it can hlep the drivers to hold the clutch at a specific point to help theirs cars to getawy at the start of the race (however, such advantage is prohibited by F1 regulations.)

What's that.. a poke in the eye to those of us who reside south of the border who chose to buy a PDK car over a manual?
After nearly a year of ownership, I'm a convert. I'd never go back to a manual. Once the PDK is mastered, it's absolutey stunning in it's performance. Maybe that's why Porsche chose to put a PDK variant in their race cars rather than a manual.. ahem..

If I remember correctly, even the brand new Porsche 918 RSR race car actually does not use PDK either, but a rather traditional 6-speed straight-toothed constant-mesh 'sequential' manual transmission. The recent RS Spyder and GT3RSR (which just won Le Mans last year) did not have PDK as well.
Most of those race cars (e.g. F1 cars) that you folks refer to in this thread are not PDK, they are just good old sequential manual transmissions with electro-hydraulics paddles that still require manual shifting action by the race drivers (no 'D' mode like in your shift gate.)

However, I HAVE TO CORRECT YOU... Porsche does NOT use PDK in ANY of their race cars! and I do KNOW it because I was part of Nuburgring and Hockenheim Porsche cup races last summer! it's either manual, or, sequential gearbox.

Reckon Porsche stopped using the dual-clutch transmssion (aka PDK) after just a few years of racing in the 1980's, and back to the sequential gearbox in their race cars -- lighter, stronger, smaller, less complex, and the constant-mesh straight-toothed gears combine with race driver skills yield almost negligible shifting time disadvantages (full automatic shift mode is prohibited in most races, anyway.)
If I remember correctly, even the brand new Porsche 918 RSR race car actually does not use PDK either, but a rather traditional 6-speed straight-toothed constant-mesh manual transmission. The recent RS Spyder and GT3RSR (which just won Le Mans last year) did not have PDK as well.

BTW, the 918 RSR uses a 6 speed paddle shift gearbox derived from the RS Spyder. It's not a "traditional....manual transmission"; no clutch pedal or shifter.

All due respect, but I'm not sure exactly what your point is. A racing sequential gearbox would be totally inappropriate for a street driven car. The dual clutch PDK, OTOH, gives most of the performance benefits of a sequential box along with the much higher degree of refinement that street driving demands. Like the sequential racing box, it doesn't require the driver to work a clutch pedal, and is essentially a manual gearbox that is shifted with paddles. Also, having the ability to put the PDK gearbox in "D", as well the manual shift mode, is a benefit that provides welcome flexibilty for the street; it's not a drawback. In concept, PDK is closer to the sequential gearboxes Porsche uses for racing, than is a conventional manual transmission.

The next generation Porsche GT3 race cars will use a PDK transmission. PDK is a lot closer to the the Seamless Shift gearboxes used in F1. I really don't understand the emotion this topic engenders. I have one of each and like them both. OTOH my RS is mostly track and I wish it had PDK - faster shifts, constant torque means up or down shifts do not cause a weight transfer - which is a big deal on a race track.
Pick your favorite and enjoy.

This is it exactly for me - if my GTS were going to be used mostly as a track car, I would have gone for PDK as it is clearly superior in that arena; as a daily driver where most of my driving is relaxed, I prefer the satisfaction of rowing my own.

If Porsche wants to offer the PDK, thats great, and if you like it, awesome. But when I stop having the choice of a manual gearbox, I would be pissed.
I have zero interest in the 458, regardless of how technically good a car it may be, because of the lack of a manual. Same goes for the new Mclaren.
