Default Porsche 911 GT3 R Hybrid

Porsche 911 GT3 R Hybrid-01porsche911gt3rhybrid.jpg


Hybrid Porsche 911 GT3 R to make world debut in Geneva
  • Innovative hybrid drive unveiled at Geneva Show prior to racing at the Nurburgring in May
  • Development of 911 GT3 racer serves as a spearhead for technology and 'racing laboratory'
  • Showcase for Porsche Intelligent Performance philosophy
  • A Porsche 911 GT3 R 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 911 GT3 R Hybrid 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. However, the focus is not on the 911 GT3 R Hybrid winning the race but rather serving as a spearhead for the technology and a 'racing laboratory' that will provide invaluable knowledge and insight on the subsequent use of hybrid technology in road-going Porsche sports cars.

110 years since Ferdinand Porsche – the company's founder - developed the world's first car with hybrid drive, the Lohner Porsche Semper Vivus, it is entirely appropriate that Porsche is once again employing this visionary drive concept in a production car-based GT racing programme.

The 911 GT3 R Hybrid
The hybrid technology featured in the 911 GT3 R Hybrid 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 911 GT3 R Hybrid. Consequently, the 911 GT3 R Hybrid 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 911 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 911 GT3 R Hybrid, by reducing the weight of the fuel tank or making pit stops less frequent, for example.

Porsche Intelligent Performance
The 911 GT3 R Hybrid is a perfect example of the Porsche Intelligent Performance philosophy, a principle to be found in every Porsche 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 Porsche 911 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 Porsche 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 Porsche is renowned, and is evident in such developments as lightweight body construction methods, Porsche Ceramic Composite Brakes (PCCB) and the Porsche Doppelkupplungsgetreibe (PDK) double-clutch gearbox.

Nice! The flywheel power generator is a pretty robust set up,and I guess we'll get to see more of it going forward,with advances in technology tweaking every bit of this system.
(thats one huge spoiler on the 911!!)

Also with all those electrical paraphernalia up front,it should account for an even better weight distribution! Brilliant!

Default Porsche 911 GT3 R Hybrid uses Williams F1 flywheel KERS



Oxford, UK, February 11, 2010. Williams Hybrid Power Limited is pleased to confirm that the energy storage system as part of the new Porsche 911 GT3 R Hybrid, which was announced today by Dr. Ing. h.c. F. Porsche AG, Stuttgart, has been developed and supplied by Williams Hybrid Power. The 911 GT3 R Hybrid with innovative hybrid drive will make its debut at the Geneva Motor Show. Further details from Porsche follow in the attached press release.

The energy storage system was originally developed for use in Formula One by the AT&T Williams team but Williams Hybrid Power is now focused on applications in road vehicles. The technology will also be developed for larger, infrastructure applications by Williams F1 at its new research facility in the Qatar Science and Technology Park.

Ian Foley, Managing Director of Williams Hybrid Power said, "We are delighted to see our technology being adopted by one of the world's leading engineering companies and most prestigious automotive manufacturers in one of their racing cars. Partnering with Porsche on this project has been a very positive experience and we are grateful to them for choosing to work with us."

Alex Burns, Chairman of Williams Hybrid Power and Chief Operating Officer of Williams F1 said, "This is a milestone for both Williams Hybrid Power and Williams F1. Together we have worked to bring this technology forward to the point where it can be tested in a racing car and deployed in a road car. We hope that this will be just the start of the evolution of hybrid systems developed for Formula One moving across to applications where they can contribute to cleaner and more powerful vehicles."

Default Re: Porsche 911 GT3 R Hybrid

In a conversation with Autocar, Porsche CEO Matthias Muller said the German car maker could consider offering a hybrid with the next generation 911. The 911 is set to get a facelift later this year, but that model will not get the addition of a hybrid motor. With the 918 Spyder, Porsche has already put a strong foot forward in the hybrid supercar race.

So is this another Formula 1 derived trickle down to road going cars? By a birds eye view of it, this looks like a Flywheel based KERS.
