The heart of the new 911 GT3 RS, the power unit, is based on the engine already featured in the 911 GT3. Like the latter, the RS power unit now displaces 3.8 instead of 3.6 litres, delivering more power and revving up faster and more dynamically.
The engine featured in the new 911 GT3 RS delivers 15 bhp more than its counterpart in the 911 GT3, that is maximum output of 450 horsepower from the fast-revving naturally-aspirated power unit. This means specific output of more than 118 bhp per litre from the six-cylinder.
The new 911 GT3 RS comes exclusively with a six-speed manual gearbox optimised 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 gears come with a shorter transmission ratio than on the 911 GT3, deliberately making concessions in terms of even higher top speed.
To improve its sporting behaviour, the new 911 GT3 RS comes for the first time with a purpose-built and specially set up PASM suspension, with wider track not only at the rear, but also on the front axle. Accordingly, the body of the new 911 GT3 RS is wider not only at the rear, but also at the front through the use of additional wheel arch covers.
The front axle comes with nine-inch-wide wheels running on 245/35 ZR 19 sports tyres, the rear axle features twelve-inch-wide wheels incorporating 325/30 ZR 19 sports tyres.
The dynamic engine mounts featured as standard also serve to improve the car's driving dynamics to a higher level. Depending on driving conditions, the mounts change in their stiffness and damping effect, improving the connection between the engine and the body when driving under very dynamic conditions.
As yet a further point the car's aerodynamics develop even more downforce than on the GT3, again benefiting the qualities of the car on the race track. Racing qualities are also why Porsche is introducing another new option in 2010, a lithium-ion battery delivered with the car and, replacing the conventional lead battery, reducing weight by more than 10 kg or 22 lb.
The new 911 GT3 RS shows its close connection to motorsport also through the dynamic looks of the car borne out in particular by its low ride height, the new, extra-large carbon-fibre rear wing with its specifically designed wing supports made of aluminium, the characteristic dual tailpipes on the extra-light titanium sports exhaust, as well as special front and rear parts exclusive to this model.
