New Porsche 911 GT3 RS



New Porsche 911 GT3 RS
The Most Sporting Road-Going 911

Stuttgart. Dr. Ing. h.c. F. Porsche AG, Stuttgart, is sending the new 911 GT3 RS to the starting line: Delivering even more engine power, offering lower weight, and featuring shorter transmission ratios as well as body and suspension elements upgraded to an even higher standard, the new 911 GT3 RS sets the foundation for homologating the racing version of the 911 GT3 and therefore offers everything it takes for ongoing success on the race track, continuing the series of absolutely uncompromising, sporting 911s homologated for the road.

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 even more power and revving up even 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, an extremely high figure for natural-aspiration technology even in the strictest worldwide comparison. And unlike many other high-performance engines, the power unit in the new 911 GT3 RS remains fully suitable for everyday use.

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 further 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 an even 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.

Sales of the new Porsche 911 GT3 RS are starting in Germany in January 2010. The Euro base-price is Euro 122,400 and US$132,800 ($163,000 CDN).- without value-added tax and national specifications.

Porsche GT3

The Porsche 911 GT3 was introduced in 1999 as a high performance version of the first water-cooled version of the Porsche 911, the 996, to continue the quarter-century tradition of low-weight RS (short for "Rennsport" in German) models that ended with the 993 RS. The GT3, named after the FIA GT class it was intended for, did not use the rather simple engine of the regular production versions of the 996, but a naturally-aspirated version of the turbocharged Porsche 962 and Porsche 911 GT1 race cars. Later, the turbo-charged Porsche 911 GT2 was added to the maker's lineup, but unlike its predecessor 993 GT2, did not fit into GT racing regulations. The racing versions of the GT3 have won several major 24h races outright, and mainly dominated their class at Le Mans. The 911 GT3 competes with the BMW M3 GTR and the Ferrari F430 GT2.

In February 2006, Porsche revealed the street-legal version of the GT3, built on the new 997 platform. Prior to that, 997 had already been in active race use for several months. In addition to a new 415 hp (309 kW) 3.6 litre flat-six engine, the vehicle features "zero lift" aerodynamics, meaning the car creates only aerodynamic downforce but no "lift", which pulls upwards and away from the road surface and affects overall grip. The vehicle now makes use of a modified, track oriented version of Porsche's active PASM suspension making this the first of Porsche's RS or GT3 versions to feature an electronically adjustable suspension system. Also available are a navigation system and Porsche's "sports chrono" gauge package, making this the most "friendly" lightweight track car the company has ever produced. The car went to sale in summer of 2006 and had a starting price of 106,000 USD. The RS was released in Europe in October 2006 and in North America in spring 2007.

The vehicle has a rated 0-60 mph time of 4.1 seconds and has a top speed of 193 miles per hour (311 km/h). Road and Track was able to achieve a 0-60 mph run in 3.8 seconds. Porsche's official test-driver Walter Röhrl completed the Nürburgring Nordschleife in 7 minutes 42 seconds with the 997 GT3. Cited in an interview with Mr. Röhrl by Swedish sports car magazine Automobil 5.06.

In 2009 Porsche launched the 2nd Generation 997 GT3, boasting an enlarged 3.8 litre engine producing 435 bhp (324 kW; 441 PS). It also featured a number of new options including dynamic engine mounts and a hydraulically lifting front axle to compensate for the low ground clearance. The rear spoiler was also modified along other parts of the bodywork. Deliveries in Europe commenced in October the same year.

As with earlier models, such as the Carrera RS 2.7 of 1973 and the Type 964 911 RS of 1991, Porsche offered an RS version of the 997 GT3. In common with its predecessors, it provides a homologation model for use in a range of racing series. Thanks to a close-ratio six-speed transmission with a single-mass flywheel, the engine revs up even more freely, thus enabling the 911 GT3 to sprint from zero to 100 km/h (62 mph) in 4.0 seconds while reaching 200 km/h (124 mph) in 13.3 seconds. Maximum speed is 310 km/h (193 mph).

The RS is 20 kg (44 lb) lighter than the GT3, weighing in at 1,375 kg (3,031 lb). This weight-saving was achieved by the use of an adjustable carbon fiber wing, a plastic engine cover, and a lightweight plastic rear window. The weight savings gives the RS model corresponding engine power to curb weight ratio of 300 bhp (220 kW) per tonne.

One characteristic of the new RS is the body, which is 44 mm (1.7 in) wider at the rear (a legacy from the Carrera 4 models with which it shares its shell) by comparison with the 911 GT3. The muscular-looking rear end conceals a wider track that not only improves directional stability but also increases the potential cornering grip of the two-seater coupe. On the other hand, drag is increased, and top speed reduced.

In addition to the new technology featured in this flat six motor car, the paint scheme and body panels are all designed specially for this car. For the RS version, the limited edition orange color was mixed specially for this car.

The American version of the RS has a standard rear window (not plexiglas) and the smaller 911 fuel tank to comply with rules of SCCA, Grand-Am, and IMSA. For Grand-Am races, the central locking wheel nut is replaced with the standard five-lug pattern required under Grand-Am rules.

Production of the first generation 997 GT3 RS ended in 2009. An estimated 413 units were delivered to the US and the worldwide production run is estimated to be under 2,000 vehicles.

For 2010, the new (or second generation) 911 GT3 RS received an additional 35 PS (26 kW; 35 hp) due to a new 3.8-liter flat-six, bringing total power output up to 450 PS (331 kW; 444 hp). This car will not be raced in the United States as both NASCAR Grand-Am, and IMSA American LeMans have not approved the new car for competition.
Porsche test driver Walter Röhrl had intended to enter the 2010 24 Hours of Nürburgring on a standard road legal 911 GT3 RS, but had to withdraw due to health reasons from the team that comprised racers Roland Asch and Patrick Simon, plus journalists Horst von Saurma and Chris Harris.

911 GT3 R Hybrid

The new Porsche 997 GT3 R Hybrid made its debut at the 2010 Geneva Motor Show. The hybrid technology featured in the car was developed by the Williams Formula One Team and is based on their F1 Kinetic Energy Recovery Systems (KERS) which they did not race in 2009. Unlike other KERS that were developed for F1, the Williams system is based on using kinetic energy stored in a flywheel rather than batteries. The GT3-R has two electric motors, each developing 80 brake horsepower (60 kW), driving the front wheels to supplements the 480 brake horsepower (360 kW) four-litre flat-six engine at the rear. It is planned to enter the car in the 2010 24 Hours Nürburgring.[4][5] As part of the build up to the 24 hour race the GT3 Hybrid made it's racing debut at the 57th ADAC Westfalenfahrt at Nürburgring on March 27 2010
