Audi, Corvette Claim Victories in Michelin Green X Challenge
Proving their race cars to be both faster and greener than the competition, Audi and Corvette scored the prototype and GT race wins respectively while winning the first Michelin Green X Challenge awards at the Twelve Hours of Sebring, the opening event of the 2009 American Le Mans Series season. Making its first race appearance, the low sulphur diesel powered Audi R15 TDI prevailed in an epic 12-hour battle against archrivals from Peugeot to claim the race victory while also using less energy. The pairs of cars from the two teams exchanged the lead 23 times in the 12-hour race that produced new records for race distance and average speed.
