The Porsche 911 RSR, which is engineered for endurance racing, was unveiled overnight.
According to Porsche, the suspension, engine, transmission, body structure, and aerodynamic aids have been “designed from scratch”.
The RSR is powered by a naturally-aspirated direct-injection 4.0-litre six-cylinder engine that’s positioned ahead of the rear axle. The engine will typically output around 375kW of power, but that will vary depending on the race and which restrictor is being used.
Drive is sent to the 31cm wide rear wheels via a six-speed sequential gearbox that’s operated via shift paddles on the steering wheel.
Porsche says that the engine and its layout has allowed its engineers to fit an extra large diffuser, as well as a rear wing inspired by the 919 Hybrid LMP1 race car, to the rear of the RSR.
To help the driver out, the 911 RSR is equipped with a collision warning system, which uses a radar to detect faster vehicles, such as LMP prototypes, approaching from behind.
While the RSR’s body has been styled to look similar to the latest 911 that’s available in showrooms, the race car’s exterior panels are all made from carbon-fibre, and can be removed and replaced quickly thanks to quick-release fasteners.
Naturally, the RSR is fitted with a stripped out race track-ready interior, complete with roll cage, adjustable pedal box, and a driver’s seat that’s fixed to the vehicle’s chassis.
The Porsche 911 RSR is available for the 2017 endurance racing season, and the company expects the RSR to compete in 19 races next year.
A factory-backed outfit with two race cars will compete in the FIA World Endurance Championship, including the 24 Hours of Le Mans.
