Dernière née de la gamme du constructeur de Stuttgart dotée de 15 chevaux de plus que la déjà très virile GT3, Porsche a dévoilé sa nouvelle GT3 RS, la version ultime de la 911 propulsée par le fameux flat-six maison poussé à 450 chevaux. Les détails dans la suite !
Équipé de roues de 19 pouces, de nouveaux appendices aérodynamiques et du dernier système de suspension réglable, le bolide a été plafonné à 310 km/h de vitesse de pointe, afin de privilégier les accélérations et les reprises en raccourcissant les rapports de la boîte manuelle à six vitesses. Pour ce qui est de l’agressivité de cette nouvelle Porsche, un seul chiffre suffira, le 0 à 100 km/h est tout simplement abattu en 4 secondes. Quand au budget, vous pouvez d’ores et déjà commencer à économiser les 147 624 euros nécessaires à vous l’offrir !
Delivering even more engine power, lower weight and shorter transmission ratios, as well as upgraded body and suspension components than all previous GT3s, the new Porsche 911 GT3 RS sets the foundation for homologating the race version of the 911 GT3 and will be introduced at the Frankfurt Motor Show September 17-27, 2009.
The heart of the new, uncompromising GT3 RS is the power unit. Like the engine featured in the 911 GT3, the naturally-aspirated RS power unit now displaces 3.8 liters and delivers even more power, while revving up even faster to its 8500 rpm redline. It now delivers 450 horsepower, 15 more horsepower than its 911 GT3 counterpart. Even with a specific output of more than 118 hp per liter from the six-cylinder boxer engine, the power unit in the new GT3 RS remains fully suitable for everyday use.
The new 911 GT3 RS comes exclusively with a six-speed manual gearbox optimized 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 transmission comes with shorter ratios than found in the 911 GT3, deliberately conceding an even higher potential top track speed.
Dynamic engine mounts are standard and serve to improve the car’s handling 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 lively conditions, yet allow for more comfortable conditions during everyday street use.
Porsche is also introducing another new option in 2010 for the GT3 RS, a lithium-ion battery. Delivered with the car and, when replacing the conventional lead-acid battery, it reduces the weight by more than 10 kg or 22 lb and is mainly intended for the track.
To further improve its sporting behavior, the new 911 GT3 RS comes with a purpose-built and specially set up PASM suspension, a wider front and rear track and corresponding bodywork.
The front axle comes with nine-inch-wide wheels running on 245/35 ZR 19 sports tires while the rear axle features twelve-inch-wide wheels incorporating 325/30 ZR 19 sports tires.
The new 911 GT3 RS shows its close connection to motorsport through its dynamic looks, in particular by its low ride height, the new, extra large carbon-fiber rear wing and titanium exhaust system.
The 2010 911 GT3 RS goes on sale in the U.S. in early spring of 2010 and will be priced at $132,800.
