Porsche test driver Walter Röhrl is set to compete in the Nürburgring 24 hour race in May 2010 with a stock standard Porsche 911 GT3 RS. The double world rally champion, now 62, returns to the famous endurance race since last competing there in 1993.

But he’s far from rusty. Röhrl has tested every standard Porsche on the Nürburgring-Nordschleife since 1993 and said this about the current GT3 RS: “Right from the word go, the 911 GT3 RS reminded me of a race vehicle. No other road-going 911 has ever been as close to a race car as this current GT3 RS. That’s why I’m thrilled to be able to prove that this sports car is up to the challenge of the 24-hour race.”

The GT3 RS is powered by a 450 bhp, 3.8-litre, six-cylinder boxer engine. Befitting its hardcore nature, it comes with extra short transmission ratios as standard. The car’s dynamic engine mounts change in their stiffness and damping to “improve the connection between the engine and body when driving under racing conditions”. These, plus a body optimised for downforce makes for a good track car out of the box.

Walter may face stiff competition from the race cars he helped to develop though – Porsche’s GT3 RSR has been dominating the race for the past four years!
