Porsche 911 GT3 R Hybrid race car revealed

Porsche will bring its latest hybrid know-how to the racetrack in the form of the new 911 GT3 R Hybrid, revealed here for the first time prior to a planned public premiere at the Geneva auto show in early March. Developed by a team of engineers at Porsche's Weissach R&D center, Porsche plans for the stripped-out race car to act as a rolling laboratory. The German carmaker wants to explore the potential of hybrid drivetrains in a racing environment before an expected announcement that it will return to the 24 Hours of Le Mans in a factory capacity, perhaps in 2012, with a race car boasting technology based on that used in the 911 GT3 R Hybrid.
