Fifty years ago, the Porsche 911 made its debut at the Frankfurt International Auto Show and ten years later the first 911 Turbo prototype made its premiere appearance at the same show.
Now, on the 40th anniversary of that first 911 Turbo, Porsche is releasing the latest generation of the 911 Turbo and Turbo S.
A new all-wheel-drive system, active rear steering, adaptive aerodynamics, full-LED headlights, and up to 560 hp from a twin-turbocharged flat six-cylinder engine reinforce the Turbo's leading role as the flagship of the 911's road-going line.
Enhancing its capability is an all-new, lightweight chassis design with a 99-mm longer wheelbase and 20-inch wheels.
In addition, the Porsche Dynamic Chassis Control (PDCC) active anti-roll system is being offered for the first time in 911 Turbo models, further increasing their dynamic performance.
PDCC is standard equipment in the 911 Turbo S, as is a Sport Chrono Package Plus with dynamic engine mounts, and Porsche Carbon Ceramic Composite Brakes (PCCB). All these features are available as options in the 911 Turbo.
Porsche's turbocharged 3.8-liter six-cylinder engine with direct fuel injection produces 520 hp in the 911 Turbo and 560 hp in the S model. Porsche is the only automaker to offer two turbochargers with variable turbine geometry on a gasoline engine.
The Turbo's seven-speed, dual-clutch (PDK) transmission now enables an auto start/stop function with engine shutoff that activates earlier while the car is coming to a stop, as well as when coasting at speed.
The engine and transmission connect with a new Porsche Traction Management (PTM) all-wheel drive system with electronically controlled and activated multi-plate coupling.
The system is equipped with a new water cooling function, which enables more drive torque to the front wheels than that in the previous 911 Turbo.
A new rear wheel steering system in all Turbo models is said to improve both track driving capability and everyday performance. It is comprised of two electro-mechanical actuators, instead of the conventional control links, on the left and right rear axles.
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, giving the same effect as shortening the wheelbase by 24.9 mm, which helps the car turn faster into corners and offers more dynamic steering response as well as simplifying maneuvering and parking.
At speeds above 80 km/h, the system steers the rear wheels parallel to the front wheels, giving the same effect as lengthening the wheelbase by 498 mm, thus adding to the car's directional control capability.
Steering input by the driver leads to significantly faster build-up of lateral force at the rear axle, which responds to steering commands even more quickly.
Further enhancing the cars' high speed capability is an active aerodynamic system, applied to the new 911 Turbo models for the first time.
It consists of a retractable three-stage front spoiler, whose segments can be pneumatically extended, and a deployable rear wing with three adjustable, driver-controlled wing positions.
In the performance position, all segments of the front spoiler are fully extendedto generate downforce on the front wheels. Similarly, the rear wing is extended to its maximum height with the greatest angle of attack, to generate more downforce at the rear.
Activation of that system alone is said to improve lap times on the North Loop of the Nürburgring by up to two seconds.
The new 911 Turbo S can now lap the North Loop in well under 7 minutes, 30 seconds, with standard production tires. It can also accelerate from 0-to-100 km/h in just 3.1 seconds and reach a top speed of 318 km/h.
Visually, the rear body panels of the new Turbomodels are 28 mm wider than on the 911 Carrera 4, with a near-level surface, abouta hand-width, extending between the C-pillar and the outer edge of the body.
Other differentiating characteristics include forged two-tone 20-inch aluminum wheels, with centre hub wheel lock on the Turbo S.
That model is further differentiated by new full-LED headlights that feature four-point daytime running lights and camera-based high/low beam control, which can be ordered as an option for the 911 Turbo.
The interior was completely redesigned in both 911 Turbo models, offering an exclusive black/Carrera-red interior and standard Sport Seats Plus with 18-way adjustment and memory.
As on the previous models, a Bose sound system is standard and, for the first time, a Burmester system is available as an option.
A radar-controlled cruise control system, camera-based road sign recognition, and speed limit recognition are other new available options.
The new models will arrive in Canada in December 2013, with prices starting at $169,200 for the Turbo and $206,600 for the Turbo S.
