GREENVILLE, S.C. (Feb. 2, 2009)—Michelin North America Inc. will be the title sponsor of the Michelin Green X Challenge environmental competition to take place alongside the 2009 American Le Mans Series.
During each 2009 ALMS racing event, beginning in March with the season opener in Sebring, Fla., two teams—one GT and one prototype class—that demonstrate the best overall performance, fuel efficiency and lowest environmental impact will receive Green X Challenge awards.
Each race car competing in the ALMS uses one of four street legal fuel alternatives: clean sulfur-free diesel, E10, cellulosic E85 or gas-electric hybrid.
All cars in the Michelin Green X Challenge are ranked based on the amount of energy used, greenhouse gas emissions and the amount of petroleum displaced, Michelin said.
The inaugural Green Challenge took place in October at Road Atlanta's Petit Le Mans, the ALMS signature 1,000-mile race. Corvette Racing, using cellulosic E85 fuel, had the best green achievement score and won the GT class challenge. Penske Racing won the prototype class challenge with its Porsche RS Spyder using E10 and direct-fuel injection.
The Michelin Green X Challenge was created jointly by the U.S. Environmental Protection Agency, U.S. Department of Energy, SAE International and ALMS.
