Endurance racer gets a KERS-style system; will compete in Nurburgring
3 March 2010

Porsche is spearheading its hybrid development with the launch of the 911 GT3 R Hybrid race car.

After its launch at the Geneva motor show, the GT3 Hybrid R will undergo extensive development at the Nurburgring and it will compete in the 24 Hours race at the circuit in May.

Porsche describes the car as a “racing laboratory”, which will provide the knowledge for its future road-going hybrid sports cars.

Powering the rear wheels is a 473bhp 4.0-litre flat-six engine. The front axle is driven by two electric motors, which each produce the equivalent of 80bhp. Porsche says this system ensures the car has greater traction and agility than the non-hybrid GT3 R.

Rather than using batteries to power the electric motors, the 911 R Hybrid uses an electric flywheel power generator. This spins at 40,000rpm and stores energy mechanically as kinetic energy. The flywheel generator is charged up when the brakes applied, with the electric motors reversing their function and acting themselves as generators.

Similar to a KERS system in Formula One, the driver is able to call on this electric power at certain opportunities to aid acceleration, overtaking or with defensive driving. This power is available for around 6-8 secs after a full recharge.

The hybrid drive can also be used to save fuel, which makes the car ideally suited to endurance racing.

All that extra kit at the front end should even up the weight distribution a little - maybe one day they might achieve the magic 50-50 ... ;o)

... as things going, one day nobody will remember that once in a long time Toyota sold a lot of Hybrids...

Probably a good thing.

Toyota Prius - Because we like devastating landmass and shipping batteries halfway around the world and call it eco-freindly

This sounds similar to the Williams F1 design for KERS. Their system was never installed during the season (as far as I know), but was apparently significantly lighter than all the other teams. (Due to the lack of batteries)

I really hope it works, as it seems like an excellent technical solution. More info on Williams system available here and here

Edit: Looks like williams are heavily involved in it. Press release here

Looks like it, http://www.autosport.com/news/grapevine.php/id/81402 Autosprt have it too.

Nice engine partner for Frank and Patrick in the future?

Fantastic to see the Williams system being used in a real-world application; i always thought it was a good KERS concept that never quite saw track time in F1.

An F1 derived system that for once has found it's way onto a road car in a fairly short time. This has to be ggod news and surely must balance up the 911 very well.

What a cracking paint job on the pictured car.

I sure hope it doesn't destroy the 911's ideal performance car weight distribution. The one that's resulted in countless racing victories over the decades. Including sweeping the American LeMans series in 2009 over all those front engined Corvettes, BMWs and the mid-engined Ferrari 430.

Hybrid technology to "save the planet" is a complete con job. Period. Hybrid technology is / has always been an interesting thing to experiment with for racing cars. I look forward to seeing how this turns out.

Oh, a hybrid GT3, the ideal dream.

Long live the electric GT3!
