owered by cellulosic E85R ethanol racing fuel made primarily from wood waste and armed with a variety of energy-saving technologies, Corvette Racing is aiming for an overall victory in the inaugural American Le Mans Series Green Challenge. This race-within-a-race will be contested on October 4 in conjunction with the 1,000-mile/10-hour Petit Le Mans at Road Atlanta, the 10th round of the 11-race series.

Under criteria developed by the U.S. Department of Energy, the U.S. Environmental Protection Agency and SAE International, the Green Challenge will determine the winning entries in the GT and Prototype classes based on performance, fuel efficiency and environmental impact. Each car will be ranked according to the amount of energy used, the greenhouse gases emitted, and the amount of petroleum displaced – while racing flat-out for a class title in the crown jewel of the ALMS.

"The Green Challenge adds an entirely new dimension to racing," said Doug Fehan, Corvette Racing program manager. "It's not simply a race to the checkered flag – the Green Challenge takes science, technology and engineering to an entirely new level in motorsports.

"The determining factors in the Green Challenge include weight, fuel consumption, the speed of the vehicle, distance traveled, emissions from the exhaust pipe, and the environmental footprint of the fuel that's used," Fehan said. "It is a huge, huge challenge, and one that we've embraced because it sends the right message – and because it's the right thing to do. Corvette Racing's commitment to green racing reflects the position of General Motors in finding new ways to power vehicles that are exciting for our customers."

While Green Challenge winners will be named in both the GT and Prototype classes, Corvette Racing is aiming for the best overall score in the competition.

"With vehicles that span the spectrum from exotic prototypes to production-based cars and fuels that range from cellulosic E10 and E85 ethanol to clean diesel and hybrids, the Green Challenge is a true benchmark for race teams to compare their engineering capabilities," said Steve Wesoloski, GM Racing Road Racing Group manager. "How does our GM small-block V-8 running on E85R ethanol stack up against Audi's TDI diesel in efficiency and environmental impact? We've taken the approach that cellulosic ethanol is an important step toward a greener future, not only in racing but in GM's gas-friendly to gas-free vehicles on the highway. The Green Challenge will give every team an unprecedented opportunity to gauge its technology against world-class competition."

One of the key elements in Corvette Racing's strategy to win the first Green Challenge title is cellulosic E85R ethanol racing fuel. This second-generation ethanol fuel has powered the twin Compuware Corvette C6.R race cars in every round of the ALMS since April. The cellulosic ethanol is made from waste wood collected in the Black Hills National Forest as part of a wildfire prevention program.
