Porsche 911 GT3 R Hybrid starts in Laguna Seca

Stuttgart. The race outing of the Porsche 911 GT3 R Hybrid Version 2.0 was trend-setting. The innovative race car achieved the same quick lap times as its top rivals yet used considerably less fuel. Just two broken transmission flanges and a collision thwarted a possible podium spot. The next test under race conditions for the further development of the particularly efficient drive technology of the 911 GT3 R Hybrid 2.0 is planned for the American Le Mans Series race on the Laguna Seca Raceway in California on 17 September. The vehicle is not eligible for championship points, as the hybrid technology is not yet a part of the GT regulations.

Two Porsche works pilots, Romain Dumas (France) and Richard Lietz (Austria) man the cockpit of the orange and white racer from Weissach. Dumas has already driven the world’s most innovative GT vehicle last year at the “Petit Le Mans”, the ALMS race on the Road Atlanta circuit. Lietz piloted the Hybrid-911 at the 24 hour races on the Nuerburgring in 2010 and 2011 as well as at various long distance races on the Nuerburgring.

“I’m so looking forward to showing this very special car at race speed to the spectators in California. Many Porsche fans live on the west coast of America, and some of them have already discovered the advantages of the hybrid system at the wheel of a Porsche Cayenne S Hybrid,” says Romain Dumas. “I’m very curious, because Laguna Seca is one of the most exciting race tracks on earth. I only know it from computer games and onboard videos. Its layout with a series of up and downhill passages should actually suit our 911 GT3 R Hybrid.”

The Porsche 911 GT3 R Hybrid 2.0, with two 75 kilowatt electric motors on the front axle supplementing the 465 hp four-litre, six-cylinder power unit at the rear, particularly embodies the philosophy of “Porsche Intelligent Performance”: The electric energy is generated during braking and stored in an electric flywheel in the 911 GT3 R Hybrid 2.0, which has undergone further development since 2010. During acceleration, this energy is automatically delivered to the front wheels, supporting the combustion engine. This leads to a reduction in fuel consumption and increases the cruising range on the circuit. Moreover, drivers can manually utilise the stored energy with a boost-paddle on the steering wheel for overtaking. Compared to its predecessor, the weight of the 911 GT3 R Hybrid was reduced from 1,350 to 1,300 kilograms.
