Following the Porsche 911 GT3 Cup, Porsche AG, Stuttgart, is entering yet another racing car in the 2010 motorsport season: The 911 GT3 R will be raced in series based on the international FIA GT3 regulations, thus succeeding the 911 GT3 Cup S. The main focus in developing this new model was on even better drivability and even easier handling.
The 911 GT3 R is powered by a four-litre six-cylinder boxer engine delivering maximum output of 480 bhp (353 kW) transmitted to the rear axle by a sequential six-speed dog gearbox.
The starting point in developing the 911 GT3 R weighing just 1,200 kg or 2,646 lb was the Porsche 911 GT3 Cup presented in September for one-make cup racing. Thanks to its increase in engine size by 0.2 litres, the GT3 R offers 30 bhp more than the Cup model. Both cars are based on the extra-wide body of the 911 GT3 RS street-legal sports car.
An anti-lock brake system (ABS), traction control and an e-gas with “throttle-blip” function make it much easier to get used to this new GT3 racing car than its predecessor, meaning that the new model is also more appropriate for the ambitious amateur racing driver.
Flared wheel arches added on to the body both front and rear bear clear testimony to the wider track than on the former model. And like all second-generation versions of the 911, the new 911 GT3 R also comes with striking LED rear light clusters.
The Porsche 911 GT3 R is making its world debut on 14 January 2010 at the Birmingham Motor Show. The car is built by Porsche’s Motorsport Department at the Weissach Development Centre and will be delivered to Customer Teams the world over as of spring 2010. The base price of the Porsche 911 GT3 R is 279,000 euros plus local sales tax/VAT.
2013 Porsche 911 GT3 R
The new Porsche 911 GT3 R based on the 997 model generation heads into the 2013 motorsport season with extensive modifications. With its widened fender flares front and rear, the successful customer sport racer, fielded in the GT3 classes, looks considerably brawnier than its predecessor. The new aerodynamics generates substantially more downforce, allowing for higher cornering speeds and later braking points. The wider track and the adapted wheels provide additional improvement in traction.
Ever since its launch in 2010, customer teams around the world have gone from success to success with the 911 GT3 R. In 2012 alone, Porsche customer teams raced the 500 hp production-based Grand Touring race car in 131 races, won 41 of them and clinched numerous championships.
For 2013, Porsche Motorsport significantly modified the aerodynamics. The front bumper panels, all fenders, the sill covers, the rear panel and underbody with rear diffuser received further fine-tuning in the wind tunnel. The rear wing was enlarged to the width of the vehicle and repositioned to work optimally with the redesigned body.
The suspension also underwent modifications. The track of both the front and rear axle grew by 50 millimetres. The width of the front rims is now twelve instead of 10.9 inches. The wheelbase of the latest 911 GT3 R grew by ten millimetres.
Like its predecessor, the highly efficient four-litre, six-cylinder flat engine has an out-put of 368 kW (500 hp). The Porsche six-speed sequential dog-type gearbox with pneumatic shift system is operated via shift paddles on the steering wheel. This technical solution allows very fast and smooth gear changes – an advantage when it comes to high operational safety and a long service life.
An array of electronic driver assistance systems adopted from the predecessor helps turn fast and safe laps. The E-gas features a throttle-blip function. The gearbox elec-tronics make skipping gears and the resulting over revving of the engine virtually impossible. Thanks to a specially-adjusted traction control and a race ABS, the 911 GT3 R can be very well controlled under braking and acceleration.
With a conversion kit offered by Porsche, customer teams can convert older model years of the 911 GT3 R to the 2013-spec. The kit is available from Porsche Motor-sport at the price of 45,500 Euros plus country-specific value added tax.
