The thrilling and historic first season for the Audi R10 TDI in the American Le Mans Series has concluded with Audi's two-car team scoring a 1-2 victory, its third of the year, at this season's final race at Laguna Seca. The victory caps an eight-race all-out win streak and mark's the first time an ALMS car has gone undefeated in its debut season. Though Audi did win every race outright this season, the two races occurring in between the 12 Hours of Sebring season opener and 24 Hours of Le Mans were ran by the R10 TDI's predecessor, the R8, that won both. Much credit should be given to the R10 TDI itself, not just for the win at Laguna Seca but for the entire winning season, as its extremely frugal use of fuel (for a 650-horsepower race car) often gave its four drivers a big competitive advantage. The drivers themselves, however, which include Allan McNish / Dindo Capello and Emanuele Pirro / Frank Biela, deserve a good deal of credit, as well, along with their teams. Most races throughout the season were never in the bag for the Audi team, each win being earned through excellent driving, pit management and the confidence that comes from piloting these Audi-engineered racers. Congrats to Audi for the unbeaten season and Capello and McNish for winning the Drivers' Title.
