Porsche Updates the 911 GT3 RSR for 2009
The most powerful race-spec 911, the GT3 RSR which is designed to compete in the GT2 class at international long distance races, has received a series of modifications for the 2009 model year. The updated 911 GT3 RSR features a more aerodynamic body, a larger capacity boxer engine as well as upgrades in the interior.In the 2009 model, the capacity of the six-cylinder boxer engine has been increased from 3.8 to 4.0-litres delivering around 450HP at 7,800 rpm and a maximum torque of 430 Nm at 7,250 rpm. Power is driven to the rear wheels through a sequential six-speed gearbox. Other mechanical changes include the weight-optimised brake system and the lighter wiring harness.
On the outside, the most distinguishing feature of the new GT3 RSR is the redesigned front-end with large air outlets on the front hood. Furthermore, Porsche optimized the GT3 RSR's underbody aerodynamics while the rear wing now features a wider adjustment range.
The 2009 911 GT3 RSR's cockpit boasts a new multi-function display located above the dashboard that tells the driver when it's the right time to change gears. Another new feature is the programmable multi-function, onboard supply system control device that gives racing teams the choice of many individual functions. One of these is the infinitely adjustable blinking frequency of the lights in the front apron, which helps to recognize race cars when they enter the pits in the dark.
The price of the updated 911 GT3 RSR has been set at €380,000 -around $490,000 US with the current exchanges rates- plus VAT specific to each country.
