2010 Porsche GT3 RS explained by Porsche

Announcing the new GT3 RS for 2010
Coming soon to a trackday near you is the new 2010 GT3 RS. The latest iteration of the 911 homologation special boasts more power, lighter weight, improved stability, and a dynamic new livery. Improvements to the intake components result in a free revving, 450hp motor that is paired with a shorter geared transmission
through a lightweight single-mass flywheel. In addition to the lighter flywheel, the door panels have been reworked to save weight, and titanium is used extensively in the exhaust to save approximately 13 lbs. Those customers wishing to save even more weight can opt for the lightweight halogen headlamps, a lithium ion battery, and can even delete the air conditioning and CDR. Lateral dynamics and stability are improved through increased downforce, PSM, and a wider front track covering 245/35/19 tires. Finally, the new livery is a dramatic statement of the GT3 RS's racing roots. For customers wishing a more subdued appearance, the wheels can be
painted in silver instead at no additional cost.
Engine:
The 2010 GT3 RS engine, based on the legendary GT1 engine, utilizes the technological enhancements first seen in the 2010 GT3, such as a larger displacement and enhanced VarioCam Plus that continuously adjusts both intake and exhaust camshafts. However, in GT3 RS guise, the 3.8 liter powerplant produces 450 hp @ 7900 rpm, and 317 lb-ft @ 6750 rpm for a specific output of 118 hp/liter. This increase in power is accomplished through modifications to the intake manifold and air cleaner. All told, those improvements result in a reduction of flow resistance of approximately 20%. The GT3 RS motor also boasts a higher compression ratio than that of the GT3 (12.2:1 vs. 12.0:1). To save weight (approximately 13lbs), the rear silencer and tailpipes are made of titanium. As in previous models, the motor features dry-sump lubrication, titanium connecting rods, forged pistons, a variable intake system, and a low-backpressure sport exhaust.
Transmission:
As in previous years, the only available transmission is a 6 speed manual. Compared to the 2010 GT3, the final drive ratio is shorter (3.89 vs. 3.44) as is 6th gear (0.88 vs. 0.92). This lower gearing in conjunction with the more powerful motor results in superior drive dynamics, especially in a track enviornment. For additional high speed engine response, a lighter single-mass flywheel is employed.
Exterior Styling:
The 2010 GT3 RS sports a completely new livery, yet remains unmistakeably a GT3 RS. Standard colors on the GT3 RS are Carrara White and Aqua Blue Metallic, and in addition to those a special color, Grey Black, is also available as an option. Each exterior color is paired with one of two contrast colors, Guards Red or White Gold Metallic. Components finished in the contrasting color are the wheels, exterior mirrors, front air intake surround, rear wing sideplates, GT3 RS badge on deck lid, and the start/finish flag and GT3 RS logos on front right and rear left fenders. At the front, the lighting strategy of the GT3 is carried over, while the front spoiler is larger and more pronounced for increased downforce. At the side one immediately notices the front fender flares that cover wider tires and allow for a wider track. In addition, the black side skirt previously seen on the GT2 manages airflow around the wide rear fenders. At the rear, the new carbon fiber wing with forged aluminum
wing supports.
Interior:
The lightweight, pared down feel of the GT3 RS continues on the inside of the car. The door panels are simplified, with a red pull strap instead of the usual door opener, and the storage box has been removed. In place of the standard dash panel trim strip, carbon fiber with an RS 3.8 logo is used. Also standard are carbon fiber door entry guards with the RS 3.8 logo. For customers looking for an even more single purpose track car, A/C can be deleted, as can the CDR. Conversely, cupholders are a no cost option on the GT3 RS. Note, as in years past, the roll bar is not offered in the US market.
Chassis:
The chassis of the GT3 RS is largely the same as that of the GT3. Notable differences include standard Dynamic Engine Mounts, wider front/rear track, and split wishbones in the rear. As in the 2008 GT3 RS, the rear track is 44 mm wider than that of the GT3. This allows use of wider tires (325), and provides greater overall grip and stability. New for 2010 is a wider front track and wider front wheels and tires. Again, this results in greater stability and grip. Like in the GT3, the Front Lift
System is optional. The new, lighter weight braking system is carried over from the GT3, and PCCBs are an option. Finally, Porsche Stability Management is now fitted as standard. This system parallels that of the GT2 in operation, which means that it increases active safety, but not at the expense of extremely sporty driving. Audio and Communications CDR 30 is fitted as standard, PCM 3.0 is optional, along with Navigation, XM Satellite Radio, Bluetooth, and iPod connectivity.
Pricing and Availability:
The GT3 will be available from early spring 2010, with a base price of $132,800.
