Just as the Porsche 911 is celebrating its 50th year this year with the launch of an all-new 911 GT3, the 911 Turbo is celebrating its 40th year by launching the all-new, seventh-generation \'Type 991\' 911 Turbo and Turbo S.
For the first time, the Porsche Dynamic Chassis Control active anti-roll system is offered on the 911 Turbo models, thereby increasing the cars\' dynamic performance potential even more. Together with the Sport Chrono Package Plus, which incorporates dynamic engine mounts into the car, and the Porsche Ceramic Composite Brakes, the 911 Turbo S reportedly shortens the benchmark lap time around the Nurburgring\'s Nordschleife circuit to under 7 minutes and 30 seconds. With a top speed of 317kph, the 911 Turbo can accelerate from zero to 100kph in 3.2 seconds, while the 911 Turbo S handles the same sprint in 3.1 seconds.
A turbocharged 3.8-liter flat-six engine with direct injection powers the 911 Turbo, with an output of 514hp for the standard model and 553hp for the Turbo S. Transferring the power to the Porsche Traction Management all-wheel drive system is a seven-speed dual-clutch transmission that has an auto start/stop function with the engine shut-off activating earlier, specifically when coasting to a halt.
Helping to intensify the driving experience is the sound symposer, which transmits \"induction sounds of the turbo engine to the passenger compartment via a speaker diaphragm.\"
Rear axle steering is also being introduced to the 911 Turbo models, improving both its track driving and everyday performance as the steering angle of the rear wheels can vary up to 2.8 degrees depending on vehicle speed. At speeds up to 50kph, when the front wheels are turned, the system steers the rear wheels in the opposite direction, virtually shortening the car\'s wheelbase by 250mm, enhancing the car\'s cornering agility. At speeds above 80kph, the system steers the rear wheels parallel to the front wheels, virtually lengthening the wheelbase by 500mm and giving the car tremendous stability, especially at high speeds.
The all-new 911 Turbo and 911 Turbo S will officially reach the global market in September 2013.
