Porsche 918 RSR Detroit Auto Show
Porsche AG, Stuttgart, is continuing to extend its performance and high efficiency competence via intensive development work in the field of hybrid technology. With the Porsche 918 RSR, the company plans to achieve a new high when it comes to Hybrid technology. In the Porsche 918 RSR, the two electric motors offer a torque vectoring function with variable torque distribution to the front axle. With the new Porsche 918 RSR racing laboratory, Porsche is now elevating this motor racing hybrid concept to an experimental level.
The Porsche 918 RSR was unveiled at the Detroit Motor Show and this just goes to show that car manufacturers are working hard to optimise and improve the performance in Hybrid cars.
The Porsche 918 RSR is a two-seat, mid-engine coupe.
The car uses a direct-injection, mid-mounted V8 engine producing 563 hp, with two electric motors on the front wheels that each produce 75kW, for a total of 767 peak hp. The front wheels are powered by the electric motors and can receive variable levels of torque. Under braking the system reverses and the electric motors become generators.
Call it a hybrid hybrid. And call it powerful. “Instead of the futuristic, ergonomically avant-garde centre console with touch-sensitive user interface from the 918 Spyder concept car, the 918 RSR’s cockpit is split by a minimalistic console with rocker switches,” Porsche said.
This Porsche flywheel accumulator made an appearance last February, when the company was getting ready to unveil the 911 GT3 R hybrid. Porsche said of the flywheel that it “is an electric motor whose rotor rotates at up to 36,000 rpm to store rotation energy. Charging occurs when the two electric motors on the front axle reverse their function during braking processes and operate as generators.
