Road-approved but race track-ready
Aerodynamics and lightweight construction
The fact that the design of the 911 GT2 RS is centred around the vehicle's racing properties is unmistakable from every angle. Drag makes way for downforce, top speed makes way for cornering speed. The wide coupé nestles low to the road. The wide front spoiler lip only leaves the necessary gap for ground clearance, contributing the most to ensuring downforce at the front axle. The striking air intakes on the aerodynamic front end and behind the doors are indications of the huge demand for cooling air required by the powertrain, brakes and charge-air coolers at full power application. The additional air vent in front of the front lid – typical for 911s in the GT class – supports the flow of air through the central radiator and simultaneously increases the aerodynamic downforce at the front axle.
Two intakes in the bonnet improve ventilation of the brake system without negatively affecting the drag coefficient. Developed by the predecessor to NASA, these “NACAs” are being used in a series-produced Porsche vehicle to cool the brakes at this point for the very first time. Motorsport technology is also evident in the front wheel arch vents of the wings. Carbon slats ensure efficient ventilation of the front wheel arches. This reduces the overpressure generated by the turning wheels, and therefore also reduces lift.
The strikingly broad side skirts also contribute to the impressive appearance of the 911 GT2 RS and its sophisticated aerodynamics: The enlarged underbody surface creates a greater vacuum. Downforce increases to exceed speed. The main part of the aerodynamically generated wheel load on the rear axle is provided by the fixed rear wing in a carbon-weave finish. The wing supports are made of forged aluminium, while the new side plates are kept in the same colour as the vehicle exterior. At a speed of 340 km/h, a total of 340 kilograms of aerodynamic downforce is exerted on the coupé. When tuned for racing, the contact pressure increases to up to 450 kilograms. Two Ram Air Scoops on the rear lid – the dynamic pressure collectors – supply the engine with combustion air. Four fins on the rear end transform the bottom engine cowling into a diffusor, thereby improving the air supply.
Lightweight design: The right material in the right places
The second visible dominant theme of the 911 GT2 RS is lightweight construction. With the torso of the 911 Turbo in an aluminium-steel composite construction, the two-seater boasts a design that is both commendably lightweight yet rigid. The front lid, front wings, wheel arch vents, outer shells on the Sport Design exterior mirrors, air intakes on the rear side sections and parts of the rear end are made from carbon-fibre-reinforced plastic, as are many of the interior components. The bonnet is also made from carbon and the roof is finished with magnesium. Both body parts have a wide lateral swage line. This contour is not simply a visually distinctive feature for the lightweight components, but also increases the rigidity of the material.
As a particularly lightweight and yet nevertheless extremely stable high-tech material, Porsche uses lightweight polyurethane with glass spheres and carbon fibre elements in the front and rear apron of the GT sports car. The rear window and rear side windows are made from lightweight glass – a real innovation at Porsche. The material is as light as polycarbonate, but also particularly resistant to scratching and breakages. Inside, the new 911 GT2 RS boasts lightweight door trims with opening loops. Drivers also have the option of dispensing with the sound system, air-conditioning system or Clubsport package to further improve the power-to-weight ratio.
Clubsport package as standard
The new 911 GT2 RS is supplied with the Clubsport package as standard. This package consists of a roll cage bolted to the body behind the front seats, a six-point seat belt in red for the driver's side, a fire extinguisher complete with mounting bracket and a preparation for the battery main switch. The switch is available separately via the Porsche motorsport department, as is the front cage bracket for motorsport events.
The school of lightweight construction: Weissach package for enhanced performance
Ever since the 918 Spyder, the Weissach package has been synonymous with increased performance through lightweight construction. The 911 GT2 RS is almost 30 kilograms lighter than that model thanks to its specially developed Weissach package. The roof and anti-roll bars on the front and rear axle are made of carbon. Even details such as the steering wheel trim and the gearshift paddles are made of the carbon material. The magnesium wheels alone, painted in satin-finish White-Gold, help the new 911 GT2 RS equipped with Weissach package shed over 11 kilograms in weight. The anti-roll bars and coupling rods save a further 5.3 kilograms in weight. This optimisation work also extends into the passenger compartment: The bolted roll cage is made of titanium and weighs around 9 kilograms less than the standard roll cage made of steel. The front lid and the carbon-weave-finish roof are emblazoned with a central strip in the same colour as the car for a visually distinctive look. The “Weissach package” logo can also be found on the headrests on the bucket seats and on a plaque on the cupholder trim.
