General Motors Corporation (GM) and Porsche AG were named on Saturday, October 4, as the inaugural winners of the Green Challenge at the Petit Le Mans, the signature endurance race of the American Le Mans Series. GM's Corvette Racing team took top honors among the Grand Touring entries, which are modified production cars, while Porsche's Penske Racing team placed first among the prototype cars. While Audi Sport North America won the actual 1,000-mile race at Road Atlanta, the Corvette and Porsche teams won the race-within-the-race by achieving the best scores for overall performance, amount of petroleum displaced, and amount of greenhouse gas emissions. According to GM, the Corvette team's low score was achieved in part by burning cellulosic E85R, a blend of 15% gasoline and 85% ethanol derived from waste wood. The American Le Mans Series partnered with DOE, the U.S. Environmental Protection Agency, and SAE International (an automotive engineering society) to develop the Green Challenge.
