Porsche has revealed the latest version of the ultimate 911, the GT3 RS and as Porsche says it’s the most dynamic 911 yet. As it’s the case with every new model everything is a little bit better, it has more power, less weight and also shorter transmission ratios, as well as upgraded body and suspension components. Designwise, you can’t expect drastic changes, but it’s been tweaked in places.

The heart of the new, uncompromising GT3 RS is the power unit. Like the engine featured in the 911 GT3, the naturally-aspirated RS power unit now displaces 3.8 liters and delivers even more power, while revving up even faster to its 8500 rpm redline. It now delivers 450 horsepower, 15 more horsepower than its 911 GT3 counterpart. Even with a specific output of more than 118 hp per liter from the six-cylinder boxer engine, the power unit in the new GT3 RS remains fully suitable for everyday use.

The new 911 GT3 RS comes exclusively with a six-speed manual gearbox optimized for short gearshift travel, low weight and high efficiency. To enhance the level of performance throughout the entire range of engine and road speed, the transmission comes with shorter ratios than found in the 911 GT3, deliberately conceding an even higher potential top track speed.

Porsche is also introducing another new option in 2010 for the GT3 RS, a lithium-ion battery. Delivered with the car and, when replacing the conventional lead-acid battery, it reduces the weight by more than 10 kg or 22 lb and is mainly intended for the track. The new 911 GT3 RS comes with a purpose-built and specially set up PASM suspension, a wider front and rear track and corresponding bodywork.The front axle comes with nine-inch-wide wheels running on 245/35 ZR 19 sports tires while the rear axle features twelve-inch-wide wheels incorporating 325/30 ZR 19 sports tires.
