The win was the third consecutive victory in America’s premier environmental motorsports competition for the Benicia, Calif. based Muscle Milk Aston Martin team.

“Our Muscle Milk team believes very much in being fast, clean, and efficient and we are very proud to earn the MICHELIN^® GREEN X^® Challenge once again,” said winning co-driver Klaus Graf. “Taking wins in both the race and the MICHELIN GREEN X Challenge means a lot to us.”

Being fast, clean, and efficient also paid off for Corvette Racing, winners of the fiercely contested GT category on the track and in the MICHELIN GREEN X Challenge
