Porsche celebrates 50 years of 911 with a new 991 GT3 [Release]

March 2013, Stuttgart. For five decades, the 911 has been the heart of the Porsche brand. Few other automobiles in the world can look back on such a long tradition and such continuity as the Porsche 911. It has been inspiring car enthusiasts the world over since its debut as the model 901 at the IAA International Automotive Show in September 1963. Today it is considered the quintessential sports car, the benchmark for all others. The 911 is also the central point of reference for all other Porsche series. From the Cayenne to the Panamera, every Porsche is the most sporting automobile in its category, and each one carries a piece of the 911 philosophy.

Porsche is marking the 911 anniversary year by starting a new chapter in the history of GT3 high performance sports cars for circuit tracks. Following the total production of 14,145 GT3 cars since 1999, the fifth generation of the 911 GT3, an all round redevelopment, is set to take on the pole position among the thoroughbred Porsche sports cars with naturally aspirated engines. Both engine and transmission, as well as body and chassis are entirely new, and extend the 911 GT3 concept with an impressive performance leap. This is due to the new active rear-wheel steering, as well as other features. The sportiest 911 will have its world premiere at the Geneva International Motor Show: the new Porsche 911 GT3.
Being the 50th anniversary year of the 911, Porsche is now set to open a new chapter in race track performance sports cars. The fifth generation of the 911 GT3, a complete new development, will take the pole position among the thoroughbred Porsche sports cars with naturally aspirated engines. Boxer engine and transmission, as well as body and chassis are completely new and constitute a further development of the 911 GT3 concept with an impressive performance leap. Power: 475 hp. Power to weight ratio: 3.0 kg/hp. Acceleration from zero to 100 km/h: in 3.5 seconds. Top speed: 315 km/h. Lap time Nürburgring Nordschleife: under 7:30 minutes. As a technical highlight, it features the first active rear wheel steering in a production Porsche. As well as the optional full LED headlights. The new 911 GT3 keeps all the successful properties of a sports car suitable for racing, with even more driving dynamics, more sophisticated practicality - and a highly emotional fun factor.

The powertrain of the new 911 GT3 is composed of a 3.8-liter boxer engine yielding 475 hp (350 kW) at 8.250 rpm, a Porsche dual-clutch transmission (PDK) and a high-traction rear-wheel drive. The six-cylinder engine is based on the same engine as the 911 Carrera S, although they share only few common parts. All other components, particularly the crankshaft and valve gear, were specially adapted or designed for the GT3. For instance, Porsche designed titanium connecting rods and forged pistons. The basic modifications set the stage for an extremely high-speed engine that reaches up to 9,000 rpm. The Porsche dual-clutch transmission was also specially developed; the characteristics are directly based on a sequential gearbox from motor racing, thereby providing further performance and dynamics advantages to the driver.

The new 911 GT3 is designed for further gains in precision and lateral dynamics throughout. Additionally, Porsche is using active rear-wheel steering for the first time. Depending on the speed, the system steers in the opposite or the same direction as the front wheels, thereby improving agility and stability. Among the other new driving dynamics features are the electronically controlled, fully variable rear differential lock, and the dynamic engine mounts. The height, toe and camber of the newly developed all-aluminium chassis is still adjustable. The new, 20-inch forged alloy wheels with central locking are used for optimal road contact.

The 911 GT3 is based on the light, yet stiff body of the current generation 911 Carrera in hybrid steel-aluminium construction, however, it comes with independent front and rear parts. In addition, the 911 GT3 is 44 millimetres wider than a 911 Carrera S in the area of the rear axle. Another clear recognition feature is again the large, fixed rear wing. This makes a decisive contribution to the exemplary aerodynamics of the new 911 GT3, which combines low air resistance, downforce with even more power.

As a result, the new 911 GT3 sets new performance records. At full acceleration from standstill, the 100 km/h mark is breached after 3.5 seconds, and 200 km/h are reached in less than twelve seconds. The top speed is 315 km/h in the seventh, top gear of the completely newly adapted PDK transmission. The lap time on the Nürburgring Nordschleife, which the new 911 GT3 manages in under 7:30 minutes, is even more impressive. Around 80 percent of all 911 GT3 are also driven on race tracks.

Together with the 911 GT3, the next generation of the racing version of the high performance sports car is being launched. The new version of the 911 GT3 Cup is thus the first race car based on the seventh generation of the iconic sports car from Stuttgart-Zuffenhausen. What is significant is the new engine is a 3.8-liter six-cylinder and the power is transferred by a newly developed six-speed constant-mesh manual gearbox independently developed by Porsche Motorsport. Thanks to the extremely rigid lightweight body in aluminum-steel composite, the latest racing car for the Porsche Mobil 1 Supercup only weighs 1,175 kilograms. More than 2,400 units of the 911 GT3 Cup have been produced since 1998, making it the best-selling racing car in the world.

At time of writing, we understand that the new 991 GT3 in Singapore will start from the vicinity of $760k before COE and options (thanks to new rules and taxes on car purchases here).
