The world is an unfair place. While most of us save every penny to possibly purchase a Porsche 911, there are others out there who just take the little coupe racing. For those select few, the bar may have just been raised. Porsche revealed the 2009 911 GT3 RSR.
Compared to last year’s model , this RSR has a redesigned front end with large air outlets on the front hood. Also, the aerodynamics and air ducts were redesigned for better air flow, the rear wing is more adjustable, and the body and some interior materials (like wiring harnesses) are lighter than the 2008 GT3 RSR .
Oh and one other thing...the engine capacity has been increased from 3.8 to 4.0-litres. Oddly enough the engine now delivers around 450 hp at 7,800 rpm, which is about 15 hp less than last year (465 hp at the higher 8,000 rpm) and develops a maximum torque of 430 Nm at 7,250 rpm, which is the same as 2008. The aerodynamics and weight loss must be what keeps this car competitive because Porsche still calls it "the quickest 911". (To Porsche: we may be willing to let you hand us the keys to the 2008 and 2009 cars for a head-to-head to settle this.)
The 2009 911 GT3 RSR starts out at €380,000 (about $494,000 at current rates). At that kind of pricing Porsche must know this car goes to a well heeled clientele, because this car now comes with one very race unfriendly compromise: optional air conditioning.
Press release after the jump.
The successful Porsche 911 GT3 RSR takes off into the new model year with extensive modifications. The most powerful race car based on the Porsche 911 , which last season secured wins in the American Le Mans Series and at the Nürburgring 24 Hours, competes in the GT2 class at international long distance races. The most distinguishing feature of the new GT3 RSR is the redesigned front with large air outlets on the front hood. Under the light-weight bodyshell, as well, major changes were made to the quickest 911.
Noticeable at first sight are the air outlet slots, or the so-called louvers, on the front hood: an indication of the completely redesigned air ducting of the radiators, which became necessary through the new design of supply and discharge air with the installation of an optional air-conditioning unit. The aerodynamics under the rear underwent further optimisation. The rear wing now features a wider adjustment range. The weight-optimised brake system and the lighter wiring harness contribute to further improved handling, compared to the predecessor model.
The capacity of the well-known six-cylinder boxer engine increased from 3.8 to 4.0-litres. After another reduction in the size of the air restrictors for the 2009 season, the engine now delivers around 450 hp (331 kW) at 7,800 revs per minute and develops a maximum torque of 430 Nm at 7,250 rpm. The rev limiter of the efficient six-cylinder unit kicks in at 9,000 rpm. Compared to the forerunner, the rev level for a given power output was significantly lowered. Thanks to this, the engine features an optimised torque curve and offers better driveability.
In the cockpit, a new multi-function display located above the dashboard indicates the opti-mum moment to change gears. Another new feature is the programmable multi-function, onboard supply system control device, giving teams the choice of many individual functions. One of these is the infinitely adjustable blinking frequency of the lights in the front apron, which helps to immediately recognise race cars when they enter the pits in the dark. For eas-ier servicing under race conditions, other modifications were made. The GT3 RSR now fea-tures a new air-jack system with overpressure valve. The oil refill with fast filling function has now moved to the rear lid, giving mechanics better access.
Aside from GT3 Cup and the GT3 Cup S, the GT3 RSR is the third race car based on the Porsche 911 offered by Porsche Motorsport. About 20 of the successful long distance racers have been built in Weissach and are now being delivered to customer teams around the world. The GT3 RSR costs 380,000 Euro plus VAT specific to each country.
