Hold onto your hats, Porsche has just unveiled the lastest version of its GT2 class racer, the GT3 RSR. Designed to compete in the international Le Mans series, the GT3 RSR is based on its predecessor the GT3 RS, but adds substantial revisions to the aero package and drive-train.
For 2009, the RSR gains a new heavily-louvered bonnet and a rear wing with added adjustability. Revised radiator duct-work accommodates an optional A/C package while weight has been stripped from the brake system and wiring harness.
Where the magic really happens is in the flat six engine, with displacement stretched to 4.0 litres. Peak power stands at 331 kW at 7800rpm with maximum torque set at 430 Nm at 7250rpm and a rev limiter that cuts in a stratospheric 9400rpm. A remapped torque curve ensures a more even spread of force throughout the rev range.
Power is transferred via a three-plate carbon-fibre clutch to a new six-speed sequential gearbox. Six-piston aliminuim callipers clamping 380mm vented discs at the front and four-piston callipers with 355mm discs at the rear keep it all on-track.
Other revisions include a relocated oil filler for easier access, new air jack system, variable blink rate for the front lights and a new multi-function display for the driver. Pricing for the RSR is set at €380,000 plus taxes.
