Carscoop recently posted a gallery of the upcoming Porsche 911 (991) Turbo cold weather testing somewhere in Europe. It shouldn’t be too long before we get to see the production 911 Turbo, perhaps towards the end of the year as a 2013 model.
Expect Porsche to keep the 3.8 liter flat-six, but replace the twin-turbo system of the 997 Turbo with a complex triple-turbo induction process similar to the systems used by BMW in their brand new M Performance models.
The Porsche system uses three individual turbochargers providing a power up to 520hp. One smaller unit is mounted close to the engine to boost low-end response together with two larger ones similar to the Borg Warner units in use today.
The system should provide a more linear delivery at the lower end of the rev range. The new induction process is claimed to improve efficiency. The new tri-turbo system is also planned for the next-generation 911 GT2 and the successor to the GT2 RS.
A source also suggests the 911 Turbo will use a seven-speed PDK dual-clutch transmission and Porsche’s new seven-speed manual gearbox. Expect a weight loss over the 997 Turbo too, as well as the new Porsche start-stop system.
Style-wise, the pictures show a wider vehicle with a more rounded appearance. The front bumper gets a facelift with the new 991 headlights and a set of daytime running lights. The iconic turbo air intakes appear to be more rounded than the outgoing model. Something Porsche wants to hide with 997 style stickers. At the back there’s a pop-up twin-deck spoiler. We’re not sure if this is something that will be carried through to the production model or if this is just camouflage.
