997 Turbo re-post--hope not
I did a search and could not find this.
The 997 Turbo Tip has two dry clutches.....no slush box here. hench the blistering 0 to 60 times. I will say that I was fooled. I thinkl it's called DSG, please correct me if I'm wrong on the name

DSG is Audis dual clutch system.
AFAIK (even though its basically something Porsche used in the 80'ies) its not available on any current models. Heard rumours about GT3's soon being offered with it though

Check out the june motortrend. Full test drive write-up on it, the type of transmission and exhaust. I don't have it handy, but the tester said that if they ever put PDK (porche's version of DSG) instead of Tip in this thing, the competitors better sell every single Ferrari and Lamborghini they can before it hits the market. That's how close to perfect this car is.
BTW, for $10 a year, motortrend is about the best auto-mag deal you can get.

The Road & Track article I was reading over the weekend said that the Auto was faster because the torque converter allowed you to spool up the turbos prior to launch. If accurate, it's a slushbox. A very fast slushbox, but a slushbox nonetheless.

Porsche is not putting DSG in any of its production cars yet. It's all rumors at this point.

At least Ferrari, BMW, Audi, and VW are now offering manual transmissions with electonically activated clutches and gear changes ala F1 cars. These can be operated as automatics. Porsche has not offered one, and I don't think the 997 Turbo has one. The fluid connection in the torque converter will allow you to rev up the engine a bit with your foot on the brake to keep the car from moving giving more boost. Thus the slushbox 997 Turbo is quicker 0-60 than the manual.

We really have no idea, just going on what we have read

Yes, the Tiptronic is faster than the manual. Porsche says improvements made to the Tip’s hydraulics allow for brake torquing on takeoff, letting the turbos spool up and deliver full boost pressure immediately. It’s faster in passing speeds, too–if only by a hair–because gearing in the Tip is such that the turbos maintain full boost pressure throughout the rev range rather than dropping off slightly at shift points.
Brake Torquing is (Google):
A procedure generally used in performance tests to improve the off-the-line acceleration of a car equipped with an automatic transmission. It is exectued by firmly dpressing the brake with the left foot, applying the throttle with the car in gear to increase engine rpm, then releasing the brakes. Brake torquing is particularly effective with turbocharged cars because it helps overcome turbo lag.
From modernracer.com:
This launch involves keeping the car stationary by flooring the brakes with the left foot, while using the right foot to rev up the engine against the torque converter.
The technique has this nagging problem (same site):
There is a lot of stress on the transmission, and the consequent heat build-up can destroy your automatic gearbox.
So, it does appear to be a traditional automatic. Maybe its was PCNA hoping for the other box. Who knows?
