Auto Car | 2011 Porsche 911 GT3 R Hybrid Race Car | Porsche said the so-called version 2.0 of the 911 GT3 R hybrid race car is lighter, more power, but the car uses less fuel, while achieving comparable lap times with that of his predecessor. The latest edition of the Porsche endurance racer will make its debut in late June on the Nürburgring 24-hour race. The hybrid system of Porsche 911 GT3 R Hybrid Race Car's weighs 20 percent less and is more efficient than last year's 911 GT3 R Hybrid, which was unveiled at the Geneva Motor Show in 2010 and made his racing debut last June at the Nurburgring.
Output of the twin electric motors that are attached to the front axle, has been boosted from 60 to 75 kW (100 hp) each. That extra 200 hp is available in short bursts, using the accelerator, the 470 horsepower 4.0-liter flat-6 engine supplement in the rear. The hybrid electric flywheel accumulator, which stores kinetic energy, is now housed in a carbon-fiber safety cell on the passenger side.
Porsche has revised the exterior, so the extra large cooling fins in the rear wings, while trimming the car's weight of 110 pounds to 2865 pounds. The cabin is also revised, with many of the controls and displays moves to the steering wheel and additional functions are controlled by illuminated buttons on the center console.
