I curious to what they are refering to as automatically double-declutching and how that affects the manual downshift procedure by the driver... wasn't that a technique needed back in the old days when gearboxes didn't have syncros?
My guess is that it's similar to the system used by Nissan with the 370Z (moving the gear lever creates an automatic rev-match by the computer).
That would make sense, but then why call it double-declutching? i.e. declucthing->moving into neutral->cluctching again->declucthing->moving into the lower gear->clutching. I looked at the original press release and it literally says double-declutching, not match-reving.
I suspect that it is just a mistranslation. There isn't a German expression specifically meaning the same as "double-declutching". The expression "Zwischengas geben" is used to cover both rev-matching and double-declutching and the wrong one of the two English possibilities was chosen in this instance when the English version of the press release was drafted.
That makes a whole lot of sense Fritz! thanks for the clarification 
Agreed -- this looks like a slightly misleading translation of the original press release...
For example, in the German press articles on the 991 Carrera 4 they make reference to...
"7-Gang Schaltgetriebe + Zwischengasfunktion (nur mit Sport Chrono Paket)" = "7-speed manual + declutching function (only with Sport Chrono Package)"
...where "Zwischengasfunktion" refers to the point under discussion...
...which is apparently the same word ("
Zwischengasfunktion") that Porsche also use to describe the "
throttle-blip" function for the
2012 Porsche 911 GT3 R race-car!

So that does sound like the new 991 Carrera 4S offers an optional "throttle-blip" function for the 7-speed manual transmission...
