Porsche Launches New 911 GT3 RSR Endurance Racer

Porsche has unveiled an updated version of its 911 GT3 RSR racecar, which will participate in next year’s GT Championship. The German firm's engineers modified the exhaust system and air intake housing, with the 4.0-liter boxer powerplant delivering 5 more horsepower, for a total of 455 hp at 7,800 rpm. While the power increase isn't much of an improvement, Porsche claims that the six-cylinder unit is better adapted to different fuel grades and its driveability is superior compared to the outgoing model.

The car also comes with a modified bodykit with a new front lip providing higher downforce, while the rear wing’s position has changed. In addition, there are larger front wheels and new LED tail lamps, borrowed from road-legal 911s.

The base price for the 911 GT3 RSR has been set at €410,000 (US $542,430), plus VAT. All the aforementioned modifications are available as a kit for the 2010 season cars.

New Porsche 911 Shows its Panamera-Style Snout in South Africa

Once again, Carscoop's photographers have caught the all-new generation of Porsche's 911 sports car series testing. However, this time, they snagged a barely camouflaged prototype not in Germany, but in South Africa. And even though our man with the camera wasn't able to capture a crystal clear shot of the front end of the 2012MY 911, it's fairly obvious that the styling is heavily influenced by the Panamera.

From there on, despite some changes here and there such as the exterior mirrors that are mounted on the doors instead of on the window frame, the redesigned tail lamps and a slightly lower roofline, the basic silhouette and proportions remain the same. An extensive aerodynamic package with an active front spoiler and variable air-intakes, is believed to be in development.

We expect more differences inside the cabin with some fresh bits and pieces borrowed directly from the Cayenne and Panamera parts bins.

The new model, codenamed '991', may look eerily similar to today's generation of the 911, but underneath the body there's a revised platform that has grown a few inches in length and width. Furthermore, Porsche's engineering team is also said to have made good use of exotic and lightweight materials to reduce the sports car's overall weight.

The 911's engine lineup will be revised with upgraded six-cylinder boxer units boasting the latest technological advancements including direct injection and start/stop systems for gains in power as well as reductions in fuel consumption and CO2 emissions. At launch, Porsche will offer two variants - the Carrera and more powerful Carrera S models, with the Turbo and other versions such as the GT2 and GT3 to follow down the line.

Delivering power to the rear or to all four wheels will be a standard six-speed manual gearbox (depending on the model) joined by an optional seven-speed PDK (Porsche Doppel Kupplung) twin-clutch transmission with shift paddles behind the wheel.

Chances are that Porsche will choose its home show in Frankfurt, Germany, next year to present the world premiere of the new 911.

A Video Tour of the Porsche Classic Workshop

Porsche Classic is a specialized workshop owned by the German automaker, responsible for repairing, servicing and even restoring classic vehicles, like this 1973 911 T Coupe. Every year, a team of 30 highly trained specialists work on around 250 cars, keeping Porsche's heritage alive. According to the Stuttgart-based company, more than 70 per cent of all Porsches ever built are still on the roads today, which is pretty impressive if you think about it. Video follows after the break.

VIDEO: New Porsche 911 GT2 RS "Driven to Extreme"

Gordon Robertson is back. Having previously tamed the GT3, the chief driving consultant of the Porsche Experience Center at Silverstone now takes on another of Stuttgart's iconic 911s: the GT2 RS.

Capable of 620 hp and 700 Nm (516 lb-ft) of torque, the 911 GT2 RS is the most powerful road-going Porsche ever built. It accelerates from standstill to 100 km/h (62 mph) in just 3.5 seconds and hits the 200 km/h (124 mph) mark in a staggering 9.8 seconds. Clearly, you need some impressive skills to drive pace the GT2 RS through a twisty circuit, but for now, you can enjoy Mr. Robertson at work in the video after the break.

More Power, Please: Wimmer RS Tunes Porsche GT2 RS to 703HP

With 620-horsepower on tap from the twin-tubo'd boxer engine for a 0-100km/h (62mph) sprint time of just 3.5 seconds and top speed of 330 km/h (205 mph), we'd argue Porsche's 911 GT2 RS is lighting quick. However, German tuning house Wimmer RS has a mind of its own when it comes to performance even if we're talking about a sports car that will be produced in a limited run of just 500 units.

The tuner's upgrades are concentrated on the 911 GT2 RS' 3.6-liter six-cylinder boxer which benefits from a remapped engine controller, optimized turbochargers, a sport air-filter, new air-intake and a valve-controlled sport exhaust system along with sport catalysts.

These modifications bump output from 620 to 703-horsepower, while peak torque rises from 700Nm to an even more impressive 810Nm or 597.5 pound-feet. According to Wimmer RS, the powered-up 911 GT2 RS can now complete the sprint from 0 to 100km/h in 3.3 seconds and pass the 200 km/h mark after just 9.5 seconds (stock model: 9.8 seconds), while continuing up to a top speed of 356 km/h or 221.2 mph.
