Overview
GT3
Launched in 2003, the Porsche 911 GT3 features a 3.6-litre, flat-six cylinder engine, derived from the Turbo and GT2 models. It produces an impressive 105bhp per litre.
The most striking visual feature of the GT3 is its unique rear wing. Combined with a unique front apron, the GT3 achieves a drag coefficient of Cd 0.30.
The brakes on the GT3 have feature six-piston callipers and larger discs fitted with Porsche-patented cooling ducts. Porsche Ceramic Composite Brake (PCCB) discs, standard on the 911 GT2, can be fitted on request.
GT3 RS
The 911 GT3 RS was a homologation model, manufactured to allow Porsche to compete in international GT racing. Around 200(?) were built.
The power to weight ratio is 4% better than the basic GT3, thanks to a weight saving of 50 kg - it tips the scales at 1,360 kilograms with a full load of fuel of 90 litres (LHD models) in the tank.
The RS, like its motor-sport predecessors, is only available with a full roll-over cage installed (front section can be removed). All cars have a white paint finish, with the inscriptions only in blue or red.
The road version of the GT3 RS features a special weight-saving rear window made of polycarbonate material and a carbon-fibre reinforced bonnet, rear wing and wing mirrors.
The engine is an extremely free-revving unit that develops 381 bhp at 7,300rpm from 3.6 litres. The maximum engine speed is 8,200 rpm and the specific output 105.8 bhp per liter. An air collector located under the rear wing uses pressure build-up there to supply extra intake air to the engine at high speeds, so that the RS reaches its maximum power output even more easily, as borne out by its performance figures. Between the engine and the gearbox the RS has a single-mass flywheel with a lower rotating mass than the double mass version.
