2009 Porsche 911 GT3 RSR

To keep pace with Ferrari domination in GT2, Porsche updated their RSR for the second year straight in 2009. To accommodate air conditioning, Porsche had to relocate the cooling system to the front of the car and include an air exit on the top of the hood. Flying Lizard, Felbermayr, IMSA Performance, Trackspeed and Endurance Asia received new cars in 2009.

Press Release

January 22, 2009 — The successful Porsche 911 GT3 RSR takes off into the new model year with extensive modifications. The most powerful race car based on the Porsche 911, which last season secured wins in the American Le Mans Series and at the
Nürburgring 24 Hours, competes in the GT2 class at international long-distance races.

The most distinguishing feature of the new GT3 RSR is the redesigned front end with large air outlets on the front hood. Under the lightweight bodyshell, major changes were also made to the quickest 911.

Indeed, the louvers on the front hood are an indication of the completely redesigned air ducting of the radiators, which became necessary through the installation of an optional air-conditioning unit. The aerodynamics under the rear underwent further optimization; the rear wing now features a wider adjustment range. The weight-optimised brake system and the lighter wiring harness contribute to improved handling compared to the previous model.

The capacity of the well-known six-cylinder boxer engine has been increased from 3.8 to 4.0
litres. After another reduction in the size of the air restrictors for the 2009 season, the engine now delivers around 450 hp at 7,800 rpm and maximum torque of 430 Nm at 7,250 rpm. The rev limiter of the efficient six-cylinder unit kicks in at 9,000 rpm. The engine also features an optimized torque curve and offers better driveability.

In the cockpit, a new multi-function display located above the dashboard indicates the optimum moment to change gears. Another new feature is the programmable multi-function, onboard supply system control device, giving teams the choice of many individual functions. For instance, it can be used to infinitely adjust the blinking frequency of the lights in the front apron, which helps identify race cars when they enter the pits in the dark. For easier servicing under race conditions, other modifications were made. The GT3 RSR now features a new air jack system with overpressure valve and the oil refill with fast filling function has now moved to the rear lid, giving mechanics better access.

Aside from GT3 Cup and the GT3 Cup S, the GT3 RSR is the third race car based on the Porsche 911 offered by Porsche Motorsport. About 20 of the successful long distance racers have been built in Weissach and are now being delivered to customer teams around the world. The GT3 RSR costs 380,000 Euro plus VAT specific to each country.
