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.

North American automakers are struggling with a nagging shortage of tires, caused in part by tire plant closings and rising demand for low-volume specialty tires. Automakers are paying much higher prices -- double-digit percentage increases from a year ago -- as tire makers gain pricing power. "We have been bombarded from every side for additional tires, and we can't keep up," said David O'Donnell, Continental Tire's vice president of original equipment in the Americas.
