The GT3R Hybrid Makes Its Debut
Porsche's GT3R proves itself worthy at the 2010 Petit Le Mans

This past weekend, the Porsche GT3 R Hybrid made its North American racing debut at the 2010 Petit Le Mans. As part of its debut, it ran in it's own experimental class during the race. Starting from the back of the grid in 43rd position, the GT3 R Hybrid clawed its way forward to finish in 18th place nine hours later.

The car completed 350 Lap, travelling 889 miles with the team of Le Mans winning drivers Timo Bernhard (Germany), Romain Dumas (France) and Mike Rockenfeller (Germany) at the wheel.

In the first hour of the race, the hybrid suffered two tire punctures, forcing two unexpected pit stops. For the Porsche engineers the race was< used as a test lab to monitor the new KERS fly-wheel system, mounted in the passenger footwell of the car.

The 911 GT3 R Hybrid is a mild hybrid car, meaning it is unable to run solely on electrical power. It uses a KERS system (kinetic energy recovery system) which utilizes a flywheel generator and a regenerative braking system to power two electric motors mounted at the front of this rear-engined vehicle. Porsche calls the system Intelligent Performance.

Although the GT3 R Hybrid is based on a car normally seen competing in the GTC Class, the hybrid system was pushing the car into lap times similar to the much lighter Porsche RSR.

Here is a great video that Porsche has produced to document the GT3R's day on the track.
