Porsche has updated one of its three factory racing 911s, the GT3 RSR, for the new model year with a number of enhancements designed to ensure it continues a successful GT2 series run. 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 Porsche made significant changes to the bodywork to ensure the GT3 RSR is more aerodynamic and has more even downforce front and rear. The changes include new air outlet slots to allow for an optional air-conditioning system and more adjustment on the rear wing to modify the handling for the conditions. Also improved is a “weight optimised” brake system and the installation of lighter wiring harness compared to the previous model.

Inside the racing cockpit is a new display that tells drivers when the best time is to change gears. Although Porsche did not go in to specifics about this, it looks similar to the system used in the Ferrari F430 and 599GTB supercars. As you can see from this gallery picture, the interior is completely stripped bare compared to a standard 911 and comes with the usual assortment of race-specific buttons.
