Porsche Cayman - Porsche Doppelkupplung (PDK) - Porsche North America
"Porsche Doppelkupplung (PDK)
Of course, you could let us take care of the gearshift strategy so that you can devote all your attention to your cornering strategy, with the optional 7-speed Porsche Doppelkupplung (PDK) featuring both manual and automatic modes. PDK offers extremely fast gear changes with no interruption in the flow of power, improved acceleration over the manual transmission, very short response times, reduced fuel consumption and a distinct increase in comfort."
You need to look into the Stingray and Hellcat some more, you're a little behind the time on those.

It is more than a matter of semantics, if you saw the Vette or Doge trans out of the car, they have a torque converter, use pumps to generate pressure, planetary sets, sprags, pawls, and all the other stuff found in all automatic transmissions. If you saw the PDK out of a Porsche, it is not similar to the current seven speed manual,
it is the seven speed manual, complete with gears, synchro rings and everything else you would find in a manual gear box, the big difference is that it uses a dual (one of even gears, one for odd) wet clutch system, and everything is controlled by computers, right down to "blipping" the throttle during down shifts.
