Mississauga, Ontario – Porsche will debut its new hybrid technology in a GT race car when it unveils the Porsche 911 GT3 R Hybrid at the Geneva Motor Show in March.
The car’s hybrid technology has been developed specifically for racing, and differs significantly from conventional hybrid systems. In the GT3 R Hybrid, an electrically-powered front axle with two electric motors supplements the 480-horsepower 4.0-litre six-cylinder engine at the rear. Instead of the batteries found in a typical hybrid road car, the electrical flywheel power generator fitted in the interior next to the driver delivers energy to the electric motors.
The flywheel generator is an electric motor, with a rotor spinning at speeds of up to 40,000 r.p.m., storing energy mechanically as rotation energy. It is charged whenever the driver applies the brake. When accelerating out of a bend or when passing, the system supplies to up 120 kW to the two electric motors in front. The additional power is available for approximately six to eight seconds after each charge process. Depending on racing conditions, the hybrid drive can also be used to save fuel, making pit stops less frequent.
Following its show debut, the 911 GT3 R Hybrid will be tested in a number of long-distance races on the Nürburgring racetrack in Germany, including the 24 Hours on the Nordschleife in May.
