German AUTO BILD 997 Turbo "Review"
But anyway, here are some points from the article in AUTO BILD:
480 HP (Germany) seems to be official now, I don't expect any substantial change anymore.
The engine is definetely based on the "old" 3.6 l engine without direct fuel injection but with the new VTG turbo chargers.
AUTO BILD claims a 0-100 kph time of 3.9 seconds for the manual and 3.8 seconds for the Tiptronic S, so the Tip really seems to be faster by 0.1 seconds. The interesting thing is: any driver can achieve 3.8 seconds with the Tip but it won't be easy to achieve each time 3.9 seconds with the manual. For red light races, the Tiptronic is definetely the better choice.
AUTO BILD also confirms the chrono sport package with the overboost function of 10 seconds to raise torque from 620 Nm to 680 Nm (~ 10%).
They also claim that the steering feels more direct/connected in the 997 Turbo compared to the 997, something which is almost hard to believe but possible.
They didn't like the sound of the engine/exhaust too much, so the rumor of an optional Porsche Sport Exhaust for the Turbo may be true.
AUTO BILD also claims that the car they "testdrove" (I suppose they were driving as co-pilots) was driving on normal winter tires without spikes and that handling performance was spectacular, even if the car sometimes had traction problems at full power (pretty normal for a 480 HP car on snow and ice).
More to come as soon as I have the magazine in my hands again, I just arrived home from Austria and I have to unpack the luggage.
