Michelin Green X Challenge heads to Lime Rock

Since then, the Michelin Green X Challenge has grown into a global initiative with the European- and Asian-based Le Mans Series and the prestigious 24 Hours of Le Mans all adopting the program to recognize the Prototype and GT car going farthest, fastest, with the smallest environmental impact at each event.

"This is an exciting time for the Michelin Green X Challenge. We are seeing acceleration in the development of new fuels, technologies and energy sources through competition," said Silvia Mammone, Michelin Motorsports manager.

"The continued migration of ALMS teams from E10 to E85R fuels, the introduction of isobutanol fuel, and the impending appearance of hybrid technologies in the series later this season are proving the relevance of the American Le Mans Series and the Michelin Green X Challenge," said Mammone.

Mammone notes that while there were no E85R fueled GT entries at the 2009 Lime Rock race, nine entries, including a single E85R entry from Risi Competizione Ferrari and pairs of E85R entries from Corvette Racing, Flying Lizard Porsche, Extreme Speed Ferrari, and BMW Rahal Letterman Racing are expected at Lime Rock this year.

In addition, the Drayson and Intersport Racing prototypes will race at Lime Rock Park (July 24) on E85R fuel, while the Dyson Mazda prototype races on the isobutanol fuel approved for ALMS competition earlier this year.
