Porsche revises 911 GT3 RSR for 2009

Porsche has made a number of revisions to the 911 GT3 RSR for 2009.
Based on the Porsche 911, the racing car notched up wins in the American Le Mans Series and Nürburgring 24 Hours last year and competes in the GT2 class in international long distance races.
Most notable of the tweaks is a re-designed nose with its large air outlets on the front panel. Louvres on the nose panel indicate re-designed air ducting for the radiators.
The aerodynamics beneath the rear of the car have also been redesigned, while the rear wing now features a wider adjustment range.
Weight-optimised braking system and a lighter wiring harness also contribute to improved driving dynamics.
The 911 GT3's six-cylinder boxer engine has been increased from 3.8 to 4.0-litres, and now outputs 450bhp at 7,800 rpm and develops maximum torque of 320lb-ft at 7,250 rpm. The rev limiter kicks in at 9,000 rpm.
Porsche says the new engine features an optimised torque curve for better driveability.
In the cockpit, a new multi-function display located above the dashboard indicates the optimum time to change gears, while a programmable multi-function, on-board supply system control device controls infinitely-adjustable blinking frequency of the lights in the front apron, which helps to immediately recognise race cars when they enter the pits at night-time in long distance endurance events.
Inside there's one bucket seat, a roll cage and fire extinguishing system. Air con is an option only.
For easier servicing under race conditions the GT3 RSR now features a new air-jack system with over-pressure valve. The oil re-fill 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 plus VAT.
