Porsche has just revealed its plans to return to the 24 hours of Nürburgring using an upgraded 911 GT3 R Hybrid, called the Version 2.0. The updated model is powered by a 4.0-liter flat-six engine churns out 470 PS (346 kW / 464 hp) along with a couple electric motors that churns out a combined output of 150 kW (201 hp / 204 PS) which is around 30 kW (40 hp / 41 PS) higher over the previous hybrid.

The flat-six engine is used for powering the rear wheels, whereas the electric motors for powering the front axle. Using this configuration, the 911 GT3 R Hybrid Version 2.0 can release up to a 200 PS (147 kW / 197 hp) boost which must prove very handy when overtaking.

Furthermore, the new GT3 R Hybrid comes with an aerodynamically optimized design which should reduce weight and fuel consumption. While on the cabin, most of the controls have been shifted to the steering wheel which allows the drivers to easily operate key functions without need to take their eyes off the track.

Hartmut Kristen, head of Porsche motorsport said :

"The emphasis of our work was on improving efficiency. That means we want to keep the lap times consistent with 2010 but use less energy, hence less fuel. In this way, we support future developments of road-going, sporting hybrid vehicles."

Nürburgring 24 hour race
Porsche lines up with an even more efficient 911 GT3 R Hybrid
Stuttgart. Porsche takes up the Nürburgring 24 hour race on 25 June with a further developed version of the Porsche 911 GT3 R Hybrid. Priority of the development was given to the improvement of efficiency through the targeted optimisation of hybrid components, which also resulted in a 20 percent weight reduction. Version 2.0 of the 911 GT3 R Hybrid is intended to achieve the same lap times as its predecessor but with less fuel consumption.
The general layout of the hybrid was adopted from the 2010 model. A portal axle with two electric motors drives the front wheels and supplements the four-litre, depending on the balance of performance classification approximately 470 hp, six-cylinder boxer engine at the rear. The output of both electric motors has increased from 60 to 75 kilowatts each. For seconds at a time, pilots now have almost an additional 200 hp at their disposal with the 911 GT3 R Hybrid 2.0. Depending on the programming, this power is automatically activated through use of the throttle pedal. Moreover, pilots can manually call up this extra power, for instance when overtaking.
The electric flywheel accumulator, with its rotor spinning up to 40,000 rpm and stor-ing energy mechanically as rotational energy, is now housed with the other hybrid components in a carbon fibre safety cell on the passenger's side.
At first glance, the new GT3 R Hybrid is clearly distinguishable from the 2010 model. Thanks to the optimisation of the hybrid system's high voltage components, the large louvres in front of the rear fenders were no longer necessary. This reduces drag and also lowers fuel consumption. All in all, the weight of the vehicle decreased from 1,350 to 1,300 kilograms.
"We've collected a great deal of information from our races on the Nürburgring, at the ALMS race at Road Atlanta in the USA, as well as from the ILMC race on China's Zhuhai circuit, which was an invaluable help for the further development of our racing laboratory," says Hartmut Kristen, head of Porsche motorsport. "The emphasis of our work was on improving efficiency. That means we want to keep the lap times consis-tent with 2010 but use less energy, hence less fuel. In this way, we support future developments of road-going, sporting hybrid vehicles."
The cockpit of the 911 GT3 R Hybrid has also been completely revised. Most of the displays and controls have moved to the steering wheel. Drivers can operate the rest of the functions via backlit buttons now situated on the centre console. Priority was placed on the ergonomics and the clear layout for pilots - particularly in darkness.
The new 911 GT3 R Hybrid is a perfect example of the ‘Porsche Intelligent Perform-ance' philosophy, a principle found in every Porsche: More power on less fuel, more efficiency and lower CO2 emissions - on the race track and on the road.
