Last year, at the same press conference where American Le Mans Series CEO Scott Atherton announced the Green Challenge, Chevrolet general manager Ed Peper announced that the C6R Corvettes would be running on cellulosic ethanol in the GT1 class. After a year of tearing up the tracks powered by non-food-sourced biofuel, GM Road Racing Group Manager Steve Wesoloski is proud of the team's accomplishments. He also welcomes Michelin on board as the title sponsor of the Green Challenge for 2009. Ethanol obviously remains a controversial fuel, but Wesoloski said, "It's going to be a long time before the auto industry finds the one magic solution. In the meantime we're all looking for answers. This [cellulosic E85] is one. We're saying you don't have to be afraid of ethanol." Lessons learned converting the race car to E85 are being shared with the production side at GM. Now, with a GT2 car under development for its debut later this year, the team is working on weight reduction by using the aluminum chassis of the production Z06 and ZR1 models. Hopefully, some of those weight reduction lessons will also make their way to production GM cars.
