Porsche 911 RSR

The 911 RSR, which contests the Sports Car World Endurance Championship (WEC) – including the 24 Hours of Le Mans – as well as the new TUDOR United SportsCar Championship GT Le Mans (GTLM) class in the USA and Canada, follows in the footsteps of its successful predecessor, the 911 GT3 RSR. It is based on the seventh generation of the iconic 911 sports car. As with the production vehicle, the wheelbase grew by approximately ten centimeters. A wishbone front suspension replaces the previously used McPherson struts. Another new development from Porsche Motorsport is the particularly lightweight racing gearbox. As previously, the six gears are selected via paddles on the steering wheel. The 470 hp (with ACO restriction), 4.0-liter six-cylinder boxer engine was taken from the car’s predecessor and extensively optimized.

Porsche 911 GT America

The Porsche 911 GT America was built specifically for racing in the GT Daytona (GTD) class (GTD) for the 2014 TUDOR United SportsCar Championship. The vehicle is an enhanced version of the new Porsche 911 GT3 Cup, the most successful, and – with more than 2,600 units built since 1998 – the most widely manufactured racecar in the world. The 911 GT America features a flat-six 4.0-liter racing engine in the rear which produces 470 hp (350 kW) at 7,750 rpm, and utilizes a six-speed sequential gearbox with pneumatic paddle shift system and electronic throttle. As with the Porsche 911 GT3 Cup and 911 RSR, drivers are safeguarded by a redesigned safety cage and race seat, specially molded around the head and shoulders. A rescue hatch in the roof provides easy access for primary medical attention and for the extrication of the driver. As with the road-legal car, the body of the new 911 GT America combines highest rigidity with low weight thanks to its smart aluminum-steel composite construction. The 911 GT America weighs around 2640 pounds per current IMSA regulations. As in the case of the 911 GT3 Cup, the suspension features higher precision and more stability at high speeds. With the wheelbase extended to 2,458 millimeters, the handling of the 911 GT America at the limit has also improved. The race braking system, newly developed for the latest version of the GT3 Cup, improves the excellent endurance qualities of the 911 GT America.

Porsche 911 GT3 R

While this particular model of the 911 GT3 R was launched in 2010 for the worldwide FIA GT3 categories, it is running in North America for the first time in 2014. Three cars are racing in the Pirelli World Challenge. Based on the sixth generation of the Porsche 911 GT3 RS street car (type 997), the 911 GT3 has flared fenders front and rear. The aerodynamics improves downforce for higher cornering speeds and later braking points, while the wider track provides additional traction. The highly efficient four-liter six-cylinder flat engine has an output of approximately 500 hp (368 kW). The Porsche six-speed sequential dog-type gearbox with pneumatic shift system is operated via shift paddles on the steering wheel.

Porsche 911 GT3 Cup

The Porsche 911 GT3 Cup is the racing version of the Porsche 911 GT3 street car. After celebrating a successful debut in the 2013 Porsche Mobil 1 Supercup, the production-based racecar, based on the seventh generation of the 911, also runs in the worldwide Porsche Carrera Cups and Challenge Cups, included the IMSA Porsche GT3 Cup Challenge by Yokohama (USA), and the Ultra 94 Porsche GT3 Cup Challenge by Michelin (Canada). Powering the Porsche 911 GT3 Cup is a 3.8-litre, six-cylinder boxer engine. Thanks to the weight-optimized modular race exhaust system, the vehicle generates 460 hp (338 KW) at 7,500 revs per minute. Power is delivered to the rear axle via a race clutch and a Porsche Motorsport designed six-speed dog-type gearbox with a mechanical limited slip differential. For the first time in a Porsche makes Cup racecar, gear shifting is performed with paddle shifts on the steering wheel.
