<strong>Speedi</strong> Wings & Wheels - August / September 2012 - Page 84 More powerful still than the 911 GT3 RSR, the Porsche 911 GT3 R is extremely popular for its forgiving handling and basic speed. And it was exactly in this direction that the improvements for the 2012 model year were targeted. The engine output was increased by 20 hp to now deliver 500 hp (368 kW). Paddle-shifts on the steering wheel ensure gear changes are even quicker and simpler, making it easier for pilots to concentrate on braking. The 1,200 kg lightweight 911 GT3 R is based on the Porsche 911 GT3 Cup (Type 997) for onemake Cup racing. Thanks to a 0.2-litre increase in engine capacity, the 2012 model GT3 R delivers 50 hp more than its Cup relatives. Both race vehicles are based on the extrawide body of the street-legal 911 GT3 RS
The 2012-spec Porsche 911 GT3 Cup is based on the lightweight 911 GT3 RS (997) street sports car. The power unit is largely identical to the production engine of the 911 GT3 RS with the same output of 450 bhp and the same maximum engine speed of 8,500 rpm. A race exhaust system with a controlled catalytic converter keeps emissions to a minimum. The vehicle cannot be approved for road use. It’s the most successful race car on earth: The Porsche 911 GT3 Cup. With over 2,200 units sold, it is the undisputed number one amongst customer racing teams all over the world. The 2012 911 GT3 Cup features a 100-litre FT3 safety fuel tank, filled via an opening in the front hood and, according to Porsche, the new tank contributes to a further improvement in safety standards. The flared wheel arches at the front axle accommodate light alloy rims measuring 9.5Jx18 with 25/64-18 Michelin race tyres. The light alloy rims at the rear measure 12Jx18 with 30/68-18 tyres. Depending on the type of racing, the new 911 GT3 Cup features different rim specifications. The blade-type anti-roll bars at the front and rear are adjustable in seven positions allowing an extremely precise set-up for each race track. Exclusive to the Porsche Mobil 1 Supercup, which runs as support to Formula 1, is the PCCB Porsche Ceramic Composite Brake. This is also available for Porsche’s road models. Compared to the composite cast brakes in the Carrera Cup cars and the GT3 Cup Challenge cars, PCCB reduces the weight of the car by around 20 kilograms. <strong>Speedi</strong> Wings & Wheels - August / September 2012 - Page 85
