porche 911 gt3 rs
The Porsche 911 GT3 is a higher performance version of the Porsche 911 sports car. The GT3 has had a successful racing career in the one make national Porsche Carrera Cup series, and the international Porsche Supercup. It has won championship and endurance races, including the GT class of the American Le Mans Series seven times, first overall in the 24 Hours of Daytona, and first overall at the 24 Hours Nürburgring six time._
Top speed 310 km/h (193 mph)
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 3.6 seconds(3.0 in the 2010 model)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.
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 IMSA American LeMans has not approved the new car for competition. Grand-Am originally did not approve the car, but after performance issues (a Porsche team did not compete at the Indy Grand Prix of Alabama round), Grand-Am approved the second-generation car in April 2010.
The 911 GT3 RS 4.0 is the final evolution of the 997 and features a 4.0 litre engine. The engine itself uses the crankshaft from the RSR with increased stroke dimensions (from 76.4mm to 80.4mm). This change has increased the power to 507 PS (373 kW; 500 hp) at 8250 rpm and 460 N·m (339 ft·lbf) of torque at 5750 rpm. Chassis development has been influenced by the GT2 RS and uses bits from other RS 911s. Front dive planes give additional downforce up front. The car weighs in at 1,370 kilograms (3,000 lb), giving it a power to weight ratio of 365bhp per ton. Only 600 cars will be built.
Performance is a 3.9 second 0-100 kilometres per hour (62 mph) time and a top speed of 193 miles per hour (311 km/h)
