According to the latest reports from Dutch magazine AutoVisie, it appears that Porsche is currently planning a limited edition of the GT3 RS, called GT3 RS Limited Edition. Just like the Porsche 911 GT2 RS, which was unveiled last year, the new 911 GT3 RS will carry a 4.0-liter engine (the standard model is powered by a 3.8-liter engine) capable to deliver 500 hp. 500 is also the number of the all 911 GT3 RS produced.
Same sources confirmed the fact that the car will be introduced to the market in late July and it appears that it will be the last edition based on the current generation, as the all-new 911 will be introduced in September at the 2011 Frankfurt Motor Show.
For those who don’t know, standard 911 GT3 RS is powered by a 3.8-liter engine delivering 450 hp which means more than 118 bhp per litre from the six-cylinder, an extremely high figure for natural-aspiration technology even in the strictest worldwide comparison.
The car also comes with a special PASM suspension and with a wider track not only at the rear, but also on the front axle. The engine is mated to a six-speed manual gearbox optimised for short gearshift travel, low weight and high efficiency.
In order to ensure that excellent performance is maintained, the power transmission was optimized. Specifically, coming in as standard in the 911 GT3 RS is the manual six-speed gearbox. It was optimized to have high efficiency, low eight, and short gear travel. In order to take the performance even higher, the gears 1-5 have a transmission ratio that is around 11% shorter when compared to the 911 GT3.
As such, after the gears have been shifted, the ongoing flow of power is improved. It even offers new potential to deliver faster acceleration than ever. For the 6th gear meanwhile, the transmission ratio is 5% shorter and thus it foregoes a higher top speed in order to maximize the racetrack performance. Supplementing the power unit of the 911 GT3 RS is the mechanical rear axle lock which gives it that asymmetric effect.
This particular feature actually comes standard on the previous model as well as the new 911 GT3. Under power, the locking action stands at 28% while in overrun it is at 40%. This means that it ensures high traction regardless of what the road surface is and also provides precise behavior when curving and does the same under load change and all through its limit. Standard as well are the dynamic engine mounts which provide a number of benefits to the car.
For example, it helps improve its driving dynamics. In addition, depending on the current driving conditions, it modifies the stiffness as well as the damping effect. It can even help improve the connection of the body to the power unit especially in cases when the driver wants a more dynamic style of motoring.
To make sure that the 911 GT3 RS continues to display higher standards when it comes to sporting performance, it has PASM suspension that is accurately set-up, extra-large brakes with the aluminum brake covers, and wheels that have a wider track and central bolts for both the front and rear. Because of this, the body of the 911 GT3 RS is wider at the rear axle. It also has extra wheel arch fairings for its front wheels.
The front wheels have a width of 9 inches and fitted on it are the sized 245/35 ZR 19 sports tyres. The rear meanwhile has the 12-inch diameter wheels with the 325/30 ZR 19 sports tyres. The Porsche Stability Management is another new feature, though for this model it has the extra-sporting version. Unlike the Traction Control on the previous model, the PSM system helps stabilize the car especially during acceleration.
It even delivers a high standard when it comes to active safety and due to the specific set-up, it is able to meet any dynamic requirements that a sporting driver may need. The control algorithm automatically switches off in two stages, when needed and was made specifically for the racetrack. Traditionally, the low weight of the 911 GT3 has been important to the brand as it results in supreme performance.
This is the reason why the most current 911 GT3 has features like its doors and bootlid being made of aluminum, as it helps make a good start in lowering the weight. Even if the body is wider, the 911 GT3 RS is 55 lbs. (about 25 kgs.) lighter when compared to the 911 GT3 which weighs at 3,021 lbs. (around 1,370 kg).
The reason for this lower weight stems from a number of changes that include a singlemass flywheel, the use of lighter materials like the titanium exhaust system, lightweight door panels, and rear window composed of a special synthetic material. Even the center panel at the rear and the rear wing are composed of composite materials.
