Porsche will be at the Geneva Motor Show (4-14.3.2010) presenting a hybrid version of the 911 GT3 R. The system was developed specifically for use in racing cars and differs in structure and in the components significantly from conventional solutions.
For example, a front-axle supplemented with two of 60 kW/82 hp electric motor the 480-hp six-cylinder boxer four liter in the rear of the 911 GT3 R. Instead of the usual street-in hybrid electric vehicles, batteries flywheel storage, which is housed inside next to the driver delivers the energy for the electric motors.
The memory of the flywheel rotor rotates at up to 40 000 revolutions per minute. The mechanical energy is stored as rotational energy. The flywheel storage is charged during braking procedures, if the two electric machines at the front axle to reverse their role and work as generators. From the loaded storage flywheel, the pilot can, if necessary, ie when accelerating out of corners or when overtaking, whose energy retrieve it by holding the flywheel in the generator is electromagnetically braked and then returns from its kinetic energy up to 120 kW power for the two electric motors at the front axle . This additional service is the driver after each charging each for a duration about six to eight seconds are available.
Energy that was previously converted into heat wasted during braking can be implemented in additional driving the Porsche. The hybrid drive will, depending on the race situation is not only efficient, but also a consumption used. This increases efficiency and allows a lower fuel weight, or subsequent pit stops.
The 911 GT3 R Hybrid will be tested after its premiere in Geneva at the Nürburgring in endurance racing. Part of the test is a start in the 24-hour race on the north loop of the Nürburgring on 15 and 16 May 2010.
