Porsche 911 GT3 R Racer unveiled

Recently, Porsche debuted its new 911 GT3 R racing car at the Autosport International Show in Birmingham, UK. A further development of the 911 GT3 Cup that was presented in September for one-make cup racing, the new 'R' model replaces the 911 GT3 Cup S in Porsche Motorsports' model range fully complying with the FIA GT3 regulations.

The GT3 R, which tips the scales at just 1,200 kg (2,646 lb), features a larger 4.0-liter (instead of 3.8-liters) six-cylinder boxer engine than the Cup model delivering 480 horsepower (+30HP) and other technical developments designed to improve the performance of the car further still.


These include an anti-lock braking system, traction control and an electronic throttle with 'blip' function on gearbox down-changes that are said to make it much easier for drivers to get used to the GT3 R race car than the prior Cup S model.

Porsche says that the new car is also more appropriate for the ambitious amateur racing driver rather than purely experienced professionals.

The GT3 also comes with additional flared wheel arches front and rear while to improve aerodynamics, the underbody of the car is completely covered and features a rear diffuser. Furthermore, compared to the prior Cup S model, the range of adjustment on the rear wing has been increased.

The fully adjustable suspension system comprises of height-adjustable McPherson struts with variable SACHS two-way shock absorbers and double coil springs up front and a rigidly mounted sub-frame with a height-adjustable multi-arm axle together with adjustable SACHS two-way shock absorbers and double coil springs at the back.


The base price of the 911 GT3 R is 279,000 Euros plus local sales tax/VAT with first deliveries to customer teams expected to begin in the spring. However, Porsche says that almost all cars for 2010 have been spoken for.

"Since we announced our intention to launch the 911 GT3 R, demand has been huge," said Uwe Brettel, Head of Porsche Motorsport Sales. "The number of GT3 R vehicles we had planned for 2010 is almost sold out."

RSR DEBUTS THE JAGUAR XKR GT2 RACECAR AT PETIT LE MANS

RASELTON, GA (September 24, 2009) – In preparation for a full championship effort in 2010, RSR has entered the Jaguar XKR GT2 in the American Le Mans Series' famed event the Petit Le Mans with the intention to introduce the car and utilize the track time for testing and development. The Jaguar brand is launched into what everyone considers the deepest GT2 class in the history of the ALMS and will have to face off against the likes of Ferrari, Porsche, BMW, Corvette, Viper, and Ford.


From a production car, the Jaguar XKR makes an excellent racecar. "The Jaguar XKR is exceptionally strong and rigid, and the construction method is in advance of the conventional steel stamping that we see in cars today," explained Paul Gentilozzi, RSR team owner. "That allows RSR to build a lighter, stronger, stiffer racecar. Also, the basic aerodynamic design of the XKR has a low drag coefficient and more than sufficient downforce."

The GT2 class features production-based cars modified as allowed by the Automobile Club de l'Ouest (ACO) rules. "There are very specific limitations. We use what we call in the industry, the Body-In-White. That is the basic skeletal structure, the sub-frames and frames from the original production car. We started our GT2 car with a real Jaguar XKR, this is not a panel built or fabricated car. We are using all of the aluminum skeletal structure of the car, the production doors, roof and deck lid."

The body work features a design that is based on the Jaguar XKR and was completed in the Jaguar Advance Design Studio headed by chief designer Ian Callum. The body has undergone intensive computational fluid dynamics work, know as CFD, by the Jaguar aerodynamics department. Information from the CFD was then incorporated into the finished body work which was made in clay at the RSR facility. Over 1100 man hours were spent during the clay process. The carbon fiber composite body work was molded and produced by a local company in Michigan and conforms to the ACO guidelines.

"The end result is a GT2 car that contains the DNA and the spirit of the Jaguar Design Department and the production car," comments Gentilozzi.

Yokohama has been announced as the official tire supplier. "Partnering with RSR on the Jaguar XKR GT2 in ALMS is a perfect fit for Yokohama," said Mark Chung, Yokohama Tire Corporation director, corporate strategy and planning. "Motorsports is a core element in what we do. It's in our DNA – we like to compete and we like to win, and so does RSR. Our collective efforts will certainly put us among the leaders in GT2 next year. We are definitely eager to get going."

RSR is working very closely with Bosch Motorsport to integrate their technologies for engine control and chassis data acquisition. The car will be equipped with a Bosch Motorsport ECU and data logger with color display, as well as Bosch spark plugs.

Gentilozzi has had a long relationship with brake supplier Brembo, winning races in Trans-Am and Champ Car. Brembo six piston front calipers on 380 mm discs with four piston rear calipers on 350 mm discs have been installed and actuated by a Tilton floating master cylinder pedal assembly. A 5.5 inch Tilton metallic clutch will allow power to flow from the modified Jaguar AJ133 engine to a Hewland CST Transaxle.

A five time Trans-Am Series Champion, Gentilozzi will wear multiple hats for the team, as not only the owner but also one of the three drivers designated to run at the Petit Le Mans. He will be joined with sports car veterans American Scott Pruett and Belgian Marc Goossens. During the testing and development process these seasoned drivers will play a key role in getting the Jaguar XKR up to speed for a strong fight in 2010.

The Jaguar XKR GT2 will make its debut in the Petit Le Mans powered by MAZDA6 at Road Atlanta in Braselton, Georgia. The 1,000-mile, 10-hour spectacle is scheduled to start 11:15 a.m. EDT on September 26. Live coverage can be seen on SPEED beginning at 11:00 a.m.
