2013 is an important jubilee for Porsche. While the 911 model attracts the attention with the celebration of its 50th anniversary, the 911 Turbo also reaches a symbolic milestone: the first prototype was presented 40 years ago at the IAA in Frankfurt.
A symbolic milestone which complements an impressive list of technical ingredients. In addition to the longer wheelbase and wider track of the 991 Carrera, the Turbo version gets a new all-wheel-drive system, the real wheel steering system unveiled on the 991 GT3 and sophisticated active aerodynamics.
The twin turbo version of the 3.8L flat six puts out 520 hp. The Turbo S raises power to 560 hp, and includes also as standard fitment the PDCC active antiroll system, the Sport Chrono pack et PCCB carbon ceramic brakes. Torque is sent to all 4 wheels through the PDK2 7 ratios twin clutch gearbox. Fuel saving strategies applied to the Carrera and Carrera S are included: stop-start system and automatic coasting system. The 0-100 km/h acceleration times are claimed at 3.2 seconds with the optional Sport Chrono pack, and 3.1s on the Turbo S. Top speed is 318 km/h. As for the new GT3, Porsche claims a lap time on the Nordschleife “well under 7’30” with standard production tires.
Rear fenders are 28mm wider than those on the 991 Carrera 4. The 991 Turbo is also fitted with a new Porsche Active Aerodynamics (PAA) with three settings for the front spoiler and rear wing.
The rear wheel steering system consists of two electro-mechanical actuators instead of the conventional control arms on the left and right of the rear axle. The steering angle of the rear wheels can be varied by up to 2.8 degrees, depending on vehicle speed. At speeds up to 50 km/h, when the front wheels are turned the system steers the rear wheels in the opposite direction. This corresponds to a virtual shortening of the wheelbase by 250 mm. At speeds above 80 km/h, the system steers the rear wheels parallel to the turned front wheels. This is equivalent to a virtual lengthening of the wheelbase by a significant 500 mm, thereby improving stability at high speeds.
Pricing is set at 162,055 euros for the 911 Turbo and 195,256 euros for the 911 Turbo S, or respectively CHF 224‘200 and CHF 270‘200 on the swiss market.
