Porsche has just unleashed its second iteration of the 911 GT3 R Hybrid race car. Porsche claims the hybrid racer is lighter and more fuel efficient than the previous version. Porsche plans to enter the 911 GT3 R Hybrid at the Nürburgring 24 hour race on June 25, 2011.
The German automaker managed to reduce the overall weight of th 911 GT3 R Hybrid race car to 20 percent, which is mainly optimized at the hybrid components. The 911 GTR Hybrid racer is now powered by two electric motors to spin the front wheels, and while the six-cylinder boxer engine at the rear. The two electric motors provide up to 200 horsepower that is available on tap for that needed boost, and the six-cylinder engine produces about 470 horsepower as the main driver.
The electric flywheel accumulator, with its rotor spinning up to 40,000 rpm and storing energy mechanically as rotational energy. Drivers could manually call this additional power through use of the throttle pedal for overtaking instances.
From the first look, the new GT3 R Hybrid is similar to the 2010 model. But through the optimization of the hybrid system’s high voltage components, the massive air intakes in front of the rear fenders were not necessarily. Hence, the weight of the vehicle has been reduced from 2,970 pounds to 2,860 pounds, and significantly more aerodynamic.
Porsche plans to race the 911 GT3 R Hybrid 2.0 at various race events throughout the year, with the first being at the Nürburgring 24 hour race event.
