After her debut in Switzerland, Porsche 911 GT3 R hybrid tested long term around the Nurburgring in Germany. The culmination of this test program will be 24 hours of racing around the circuit 14-mile Nurburgring Nordschleife 15/16 May 2010. However, the emphasis is not on the Porsche 911 GT3 R hybrid race win, but rather serves as a spearhead in technology and laboratory race, which will provide valuable knowledge and insight on the future use of hybrid technology on public roads Porsche sports cars.
110 years since Ferdinand Porsche - Founder of the company - has developed the first hybrid car powered world, the Lohner Porsche Semper Vivus, is entirely appropriate that Porsche is once again with this unity of vision concept in a program production-based GT race car.
The hybrid technology featured in the Porsche 911 GT3 R hybrid was developed specifically for the race, and unlike conventional hybrid systems in the configuration and component selection. Individual electric front axles with two electric motors each developing 60 kW 480 hp family supplements (353 kW) petrol engine with four-cylinder flat-six 'boxer' in the back of the Porsche 911 GT3 R hybrids. Therefore, the Porsche 911 GT3 R hybrid four-wheel drive provides traction and agility.
Another important point is that instead of the usual battery of conventional hybrid road car powered, the 911 has a generator of electric steering wheel - mounted inside the cab beside the driver - which transmits energy to the electric motors in the front axle.
Flywheel itself is an electric motor - the rotor can rotate up to 40,000 rpm - and store mechanical energy of the cycle, or kinetic energy. Flywheel for whenever the driver to brake, in which two electric motors to turn the front axle of their activities and act as self-generators.
The driver is able to draw extra energy from charging the battery charged at his command for competitive advantage, as when accelerating out of a turn or overtaking. generator driving slower electromagnetic generator of fashion and can provide up to 120 kW for two electric motors to the front axle of its kinetic energy resources. This extra power is available to the teacher after each charging process about 6-8 seconds.
The energy previously converted into heat and therefore lost after applying the brakes are now converted very efficiently to the extra power.
Under race conditions, hybrid engines are used in this case not only for the extra power, but also to save fuel. This performance increases efficiency and thus the Porsche 911 GT3 R hybrid, by reducing the weight of the fuel tank or make pit stops less frequent, for example.
Porsche Performance Smart
Porsche 911 GT3 R Hybrid is a perfect example of the philosophy of Porsche intelligent performance, a principle is found in all Porsche, defined as more power with less fuel, more efficiency and reduce CO2 emissions - on the race track and on the road. Already, customers can buy a Porsche 911 coupe with an engine power six-cylinder 345 that can return nearly 30mpg combined and produces only 225 g / km of CO2, a feat unmatched in its class and an example of the implementation of Porsche Intelligent maintain outstanding performance driving dynamics also lower operating costs and environmental impact.
Design of intelligent solutions designed to combine individual performance and efficiency in daily use is something for which Porsche is recognized and is evident in developments such as methods of body light Porsche Ceramic Composite Brake (PCCB) and the Porsche Doppelkupplungsgetreibe (PDK) dual-clutch gearbox.
