 A rong class="keyword">rong class="keyword">rong class="keyword">rong class="keyword">Porscherong> rong class="keyword">911rong>rong> rong class="keyword">GT3rong>rong> Rrong> with innovative hybrid drive will be unveiled at the Geneva Motor Show in March, taking the evolution of the iconic sports coupe to new levels in motor sport and opening a new chapter in an illustrious racing record that has witnessed more than 20,000 victories in 45 years. After its debut in Switzerland, the rong class="keyword">rong class="keyword">rong class="keyword">rong class="keyword">911rong> rong class="keyword">GT3rong>rong> Rrong> Hybridrong> will be tested in long-distance races around the Nürburgring, Germany. The highlight of this test programme will be the 24 Hours race around the 14-mile Nürburgring Nordschleife circuit on 15/16 May.
More from PRESS RELEASE :
110 years since Ferdinand rong class="keyword">Porscherong> – the company’s founder - developed the world’s first car with hybrid drive, the Lohner rong class="keyword">Porscherong> Semper Vivus, it is entirely appropriate that rong class="keyword">Porscherong> is once again employing this visionary drive concept in a production car-based GT racing programme.
The rong class="keyword">rong class="keyword">rong class="keyword">rong class="keyword">911rong> rong class="keyword">GT3rong>rong> Rrong> Hybridrong>
The hybrid technology featured in the rong class="keyword">rong class="keyword">rong class="keyword">rong class="keyword">911rong> rong class="keyword">GT3rong>rong> Rrong> Hybridrong> has been developed especially for racing, and is set apart from conventional hybrid systems in its configuration and choice of components. Uniquely, an electrical front axle drive with two electric motors each developing 60 kW supplements the familiar 480 hp (353 kW) four-litre flat-six ‘boxer’ petrol engine at the rear of the rong class="keyword">rong class="keyword">rong class="keyword">rong class="keyword">911rong> rong class="keyword">GT3rong>rong> Rrong> Hybridrong>. Consequently, the rong class="keyword">rong class="keyword">rong class="keyword">rong class="keyword">911rong> rong class="keyword">GT3rong>rong> Rrong> Hybridrong> has four driven wheels, offering even greater traction and agility.
A further significant point is that instead of the usual batteries of a conventional hybrid-powered road car, this rong class="keyword">911rong> features an electric flywheel power generator – mounted inside the cockpit beside the driver – that delivers energy to the electric motors on the front axle.
The flywheel generator itself is an electric motor - with its rotor capable of spinning at speeds of up to 40,000 rpm - and stores energy mechanically as rotation, or kinetic, energy. The flywheel generator is charged-up whenever the driver applies the brakes, with the two electric motors reversing their function on the front axle and acting themselves as generators.
The driver is able to call upon this extra energy from the charged flywheel generator at his command for competitive advantage, such as when accelerating out of a bend or overtaking. The flywheel generator is slowed down electromagnetically in the generator mode and able to supply up to 120 kW to the two electric motors at the front axle from its resource of kinetic energy. This additional power is available to the driver after each charge process for approximately 6 - 8 seconds.
Energy formerly converted into heat, and thus wasted, upon every application of the brakes is now converted highly efficiently into additional drive power.
Depending on racing conditions, hybrid drive is used in this case not only for extra power, but also to save fuel. This again increases the efficiency and, accordingly, the performance of the rong class="keyword">rong class="keyword">rong class="keyword">rong class="keyword">911rong> rong class="keyword">GT3rong>rong> Rrong> Hybridrong>, by reducing the weight of the fuel tank or making pit stops less frequent, for example.
rong class="keyword">Porscherong> Intelligent Performance
The rong class="keyword">rong class="keyword">rong class="keyword">rong class="keyword">911rong> rong class="keyword">GT3rong>rong> Rrong> Hybridrong> is a perfect example of the rong class="keyword">Porscherong> Intelligent Performance philosophy, a principle to be found in every rong class="keyword">Porscherong> and defined as more power on less fuel, more efficiency and lower CO2 emissions – on the race track and on the road. Already, customers can buy a rong class="keyword">rong class="keyword">Porscherong> rong class="keyword">911rong>rong> coupe with a six-cylinder 345 bhp engine which can return nearly 30mpg Combined and produces just 225 g/km CO2; a feat unrivalled in its performance class and just one example of the application of rong class="keyword">Porscherong> Intelligent Performance to maintain outstanding driving dynamics yet lower running costs and environmental impact.
Devising smart, individual engineering solutions to combine performance and efficiency with everyday usability is something for which rong class="keyword">Porscherong> is renowned, and is evident in such developments as lightweight body construction methods, rong class="keyword">Porscherong> Ceramic Composite Brakes (PCCB) and the rong class="keyword">Porscherong> Doppelkupplungsgetreibe (PDK) double-clutch gearbox.
