Porsche 991 Turbo: Frankfurt Motor Show 2013 Spy Pics
Killer-M | On 30, Mar 2013
So it looks like it will be official, Porsche AG is looking to debut the 2013 Porsche 991 Turbo at the Frankfurt Motor Show in September 2013. There’s a lot of speculation around this supercar, however it’s safe to say that the turbocharged engine will be a 3.8 liter six cylinder, boxer layout (that means the cylinders are horizontally opposed to each other). Power will be applied to an all wheel drive system with a max output in at 530 hp – slightly more than the outgoing Porsche 997 Turbo S.
These Spy pictures show the turbo with PCCB (Porsche Ceramic Composite Breaks) which come as an option.
There’s still quite a bit of speculation on whether the 991 turbo’s power will be assisted with three or the standard two turbos. A three turbo configuration would consist of a small diameter fast spooling turbo for low end power which would transition the forced air induction to two larger turbos (possibly variable vane) on higher RPM’s. The idea would be an even better reduction to turbo lag – which would make this car simply insane in a 0-100 kph sprint and and 0-200 kph (120 mph) should then come nicely under 10 seconds – a monumental feet for a stock Porsche!
A few points that we believe are spot on when it comes to the Porsche 991 turbo:
- It has active aero. A rubber tube similar to a bicycle tire runs along the underside of the front spoiler. In Sport Plus mode, it fills with air, extending downward as a spoiler to swap the 911’s inherent front-end lift for slight down-force. Top speed is limited to 196 mph on the Turbo S because it’s all the tires can handle—otherwise the new rocket would be capable of 207.
- The optional ceramic brake discs measure 16.1 inches in front, 15.4 in the rear. In other words, they’re enormous.
- In the past, Turbo models used the Porsche Carrera 4’s wide body. This time, the Turbo is even wider. C4 models are 1.7 inches wider than the base 911; add another 1.1 inches for the Turbo!
- Angry mobs, grab your pitchforks. There’s no more manual—PDK is the only transmission now. The center differential is now a computer-controlled, water-cooled Haldex unit that can send 13 percent more power up front.
- Additional boost (up to 17.4 psi) and additional revs (up to 7200) means additional power: the Turbo makes 520 hp and 479 lb-ft. The Turbo S makes 560 hp and 516 lb-ft. Each motor gets an over-boost function, producing another 37 lb-ft for up to ten seconds.
- Like the Porsche GT3, the 911 Turbo uses rear active steering for more maneuverability at low speeds and more stability at high speeds.
- The Turbo’s roof can be painted, made of glass, or made of carbon fiber, a la the Porsche GT3 Cup car.
- Not that anyone cares, but the Turbo uses some 13% less fuel than the last one. Partial thanks go to the virtual-gear programming in the PDK that uses clutch slippage to “fake” an appropriate gear ratio. It aims to keeps revs near 1000 rpm under low-speed, low-load conditions. Start/stop is standard, and now turns the engine off under 4 mph.
- The last Turbo and Turbo S flew around the Nürburgring in 7:39 and 7:37, respectively. The new car does it in under 7:30, meaning it could match the Porsche Carrera GT’s 7:25. Look for a 0-60 time of around 3 seconds flat.
