Porsche upgrades the 911 GT3 RSR

Article by Christian A., on August 29, 2010

The GT3 RSR, one of Porsche's three production racing 911s, have been upgraded for the new model year with numerous improvements intended to guarantee that it will continue the GT2 series successfully.

The external improvements involved considerable alterations to the bodywork to guarantee added aerodynamics and front and rear downforce.

These enhancements consist of fresh air outtake vents to accommodate an air-conditioning system option and more adaptability to the wing at the rear to improve handling.

The brake system, which has been 'weight optimized', is part of the improvement, as well as the installation of much lighter wiring harness in contrast to the preceding version. More improvements were done to the engine, with its 6-cylinder Porsche boxer receiving a displacement upgrade from 3.8 to 4.0-liter.

The latest RSR can now generate 450 hp (to last year's model of 465hp) and 430Nm of torque, thanks to a size reduction of its air restrictors for this year's season.

Although the power may be lower, it is claimed by Porsche that the current model is easier to handle due to higher power yield at lower rpms throughout the range and a superior torque curve.

On the interior the RSR received new display equipment that informs the driver the best time to change gears for optimum performance, besides this however the interior has been stripped to the level of a regular 911 and is equipped with the same list of race-specific buttons.

The cost for the RSR is 380,000 Euros (around $500,000) about $300,000 above the price of a 911 GT2.

Press Release

Porsche 911 GT3 RSR

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.
