Porsche 911 GT3 R, 2010

Porsche 911 GT3 R, 2010

Developed for racing series based on the international FIA GT3 regulations, the stunning Porsche 911 GT3 R succeeds the 911 GT3 Cup S and is delivered to customers ready-to-race. The starting point in developing the Porsche 911 GT3 R was the latest 3.8-litre Porsche 911 GT3 Cup, which will compete in the 2010 Porsche Mobil 1 Supercup supporting selected Formula One races. However, the Porsche 911 GT3 R - which weighs just 1,200 kg (2,646 lb) - has a larger 4.0-litre six-cylinder 'boxer' engine delivering 480 bhp and other technical developments designed to improve the performance of the car further still.

For example, an anti-lock braking system, traction control and an electronic throttle with 'blip' function on gearbox down-changes make it much easier for drivers to get used to the Porsche 911 GT3 R race car than the prior Cup S model, with the consequence that the new car is also more appropriate for the ambitious amateur racing driver rather than purely experienced professionals. The main focus with this new car was to deliver even better driveability and easier handling.

Additional flared wheel arches front and rear emphasise the purposeful, wide track of the Porsche 911 GT3 R. And like all second generation versions of the 911, the new Porsche 911 GT3 R also comes with striking LED rear light clusters. For optimal aerodynamic performance, the underbody of the car is completely covered and features a rear diffuser and, compared to the prior Cup S model, the range of adjustment on the rear wing has been increased.

The highly-developed suspension can also be adjusted extensively; at the front are height-adjustable MacPherson struts with variable SACHS two-way shock absorbers and double coil springs (main and auxiliary). At the rear, the Porsche 911 GT3 R features a rigidly mounted sub-frame with a height-adjustable multi-arm axle together with adjustable SACHS two-way shock absorbers and double coil springs.

As the newest Porsche race car, the 911 GT3 R has an incredible provenance. In 2009, the ultimate racing Porsche 911 - the GT3 RSR - won the GT2 Drivers' title in the FIA GT Championship, the GT2 title in the American Le Mans Series and also in the Le Mans Series of endurance races, and also triumphed in the gruelling 24 Hours of the Nurburgring race.

Like the 911 GT3 Cup and 911 GT3 RSR, the Porsche 911 GT3 R is designed and built by the Porsche Motorsport Department at the company's Weissach Development Centre. First deliveries to customer teams around the world begin in the spring, and the base price of the Porsche 911 GT3 R is 279,000 Euros plus local sales tax/VAT.

Porsche 911 GT3 Cup, 2010

Stronger, wider, faster - the new Porsche 911 GT3 Cup car is the latest-edition of the world's best-selling and most successful production-based race car of more than 1,400 units. It will be introduced at the Frankfurt Motor Show September 17-27, 2009, along side the previously-announced 2010 Porsche 911 Turbo and 911 GT3 RS.

For the first time, the race car is based on the street-legal 2010 GT3 RS version. However, in keeping with tradition, it continues to be assembled on the same production line as all road-going Porsche 911 vehicles in Stuttgart-Zuffenhausen.

Like the flat-six "Boxer" engine in the new GT3 RS, displacement is increased by 0.2 liters over the former model to 3.8 liters and produces 30 more horsepower - 450 hp with a maximum RPM of 8,500. Additionally, it comes with a standard, sequential six-speed manual gearbox and weighs 2,646 lbs (1,200 kg).

Also like the 911 GT3 RS, the Porsche 911 GT3 Cup car features the 1.73-inch wider body of the current 911 Carrera 4S, providing sufficient space for larger wheels. Wider front wheel arches allow for three-piece light-alloy rims measuring 9.5 J x 18 (previously 9 J x 18) utilizing 24/64-18 Michelin racing tires. The three-piece light-alloy wheels on the rear axle are up by one inch in width, now measuring 12 J x 18 with 27/68-18 tires.

The Porsche 911 GT3 Cup is clearly recognizable at first sight through the special design of the front end. The striking daytime driving lights come straight from the current generation 911. Another carryover from the road-going 911 GT3 RS are the front body panels - as they prove aerodynamically-efficient for racing duty. The front spoiler lip is more than 0.5-inches lower to provide significantly more downforce on the front axle.

Downforce on the rear axle is also increased by the by virtue of a rear wing that is over 9-inches wider than the street version, 66.9 inches vs. 57.5 inches respectively. The rear air dam, with its air vent openings as well as the rear LED lights, also come straight from the road model.

Additional Unibal joints are featured on the track control arms and the front and rear anti-roll bars are now adjustable to seven different positions, allowing for an even more precise set-up of the car to best match each prospective race track.

The cockpit of the new Porsche 911 GT3 Cup caters even more to the specific needs of the driver. An additional vent in the upper part of the front lid, for example, provides the driver with a better supply of fresh air. The controls for the Info Display are now positioned directly on the steering wheel housing. And in addition to fore-and-aft adjustment, the steering wheel may now also be adjusted for height as on the regular production car.

Since the current era of sports car racing in the U.S started in 1999, Porsche 911 race cars have over 130 class victories, more than any other manufacturer. In addition, Porsche has won seven of ten GT2 manufacturers' championships and eight of ten drivers' championships in the American Le Mans Series. In addition, 911 race cars have won seven of nine GT championships in the Grand-Am Road Racing series, including an overall victory at the Rolex 24 at Daytona.

Porsche 911 GT3, 2010

Porsche 911 GT3, 2010

The new Porsche 911 GT3 is the latest evolution of an iconic sports car. Embodying the essence of more than 23,000 Porsche racing victories, the 911 GT3 is the ultimate integration of driver and car and arrives in the UK this autumn.

In developing the second generation of the Type 997 911 GT3 into the most sporting and dynamic road-going 911 ever with a naturally-aspirated power unit, Porsche has applied a wide range of know-how gained in motor sport. Indeed, this is precisely why the new Porsche 911 GT3 is truly impressive not only on the road, but also on the race track.

The Porsche 911 GT3 offers an even higher standard above all in two key areas: performance and driving dynamics. The proven six-cylinder naturally aspirated power unit now develops a maximum output of 435 hp (320 kW), up 20 hp over its predecessor. This results first and foremost from an increase in engine capacity by 200 cc to 3.8-litres and from improved cylinder head gas flow: now not only the intake, but for the first time also the exhaust camshafts, are adjusted by VarioCam.

A further important point is that, through its upgraded power and performance, the flat six 'boxer' engine also offers a significant increase in torque at medium engine speeds, a benefit of particular significance in everyday motoring. Clearly, this also means a further improvement in performance; the new Porsche 911 GT3 accelerates from a standstill to 62 mph (100 km/h) in 4.1 seconds and reaches 99 mph (160 km/h) in 8.2 seconds. Top speed is 194 mph.

The second emphasis in developing the Porsche 911 GT3 to an even higher standard was to further improve the car's driving dynamics. For the first time, the Porsche 911 GT3 comes with a particularly sporting variant of Porsche Stability Management (PSM), offering the facility to deactivate both Stability Control (SC) and Traction Control (TC) in separate steps. And to give the driver unrestricted, individual control over the driving dynamics of his car, these functions are not reactivated automatically even under the most extreme driving conditions, but only at the touch of a button.

The new Porsche 911 GT3 offers increased grip and stability at high speeds, courtesy of specific modifications to the car's aerodynamics which have increased downforce front and rear to such an extent that the overall air pressure pushing down on the car is more than twice as great as on the former model. At the same time, the new 'Aerodynamics Package' gives the Porsche 911 GT3 a distinctive appearance which is further accentuated by new Bi-Xenon headlights, LED rear light clusters, and modified air intakes and outlets.

The Porsche Active Suspension Management (PASM) fitted to the 911 GT3 has enabled Porsche engineers to make the springs and anti-roll bars stiffer yet again, thus ensuring even more precise handling in the PASM 'sports' mode. However, the PASM ensures appropriate ride comfort suitable for everyday use when in the 'normal' PASM mode. The Porsche 911 GT3 rides on new, lighter wheels in a racing-inspired design - with a centre locking nut - fitted with ultra-high performance (UHP) tyres. Tyre pressure monitoring is fitted as standard.

With driving dynamics and performance increasing to an even higher level, following Porsche tradition the braking system has also been enhanced accordingly on the new 911 GT3. The brakes now feature larger friction discs and an aluminium cover to reduce un-sprung weight further still. Brake ventilation has been improved, which guarantees a higher level of consistent stopping power over long periods. As an option, the Porsche 911 GT3 comes as before with an exclusive version of the Porsche Ceramic Composite Brakes (PCCB) made specifically for this model.
