In the latest post on the GM Fastlane blog, Corvette chief engineer Tom Wallace describes what he calls the greatest victory yet for the Corvette Racing team. Just over a week ago at the Petit Le Mans at Road Atlanta, the Corvette C6R of Johnny O'Connell, Jan Magnussen, and Ron Fellows became the first ever GT class winner of the ALMS Green Challenge. The American Le Mans Series debuted the Green Challenge as part of the PLM to measure the environmental impact of the competitors. The challenge measures the fuel consumption and well-to-wheel impact of the fuels used by the racers in a formula combined with on-track performance. Efficiency is always an important element in racing, particularly endurance racing because it allows the cars to run longer between fuel stops. The Corvette team had already optimized the C6R to minimize friction and drag. The key to the Green Challenge victory was the fuel used by the Corvettes. They have been running through most of the 2008 season on cellulosic E85 made by KL Engineering.
