C6.R

* 2005 The C6.R was unveiled for its first race at the 2005 12 Hours of Sebring endurance race of the American Le Mans Series. Later, in the 2005 24 Hours of Le Mans, it made up for Sebring by placing first and second in the GT1 car class (5th and 6th overall) after a lengthy duel with the Aston Martin team’s DBR9 racers. Corvette C6.R went on to win its class at every race it entered in the 2005 ALMS season.
* 2006 In 2006 Corvette C6.R won both American Le Mans GT1 Championships: Teams and Manufacturers.
* 2007 On March 17, 2007 the C6.R won the GT1 class in the 12 Hours of Sebring. For Le Mans 2007, there were four C6.R’s on the entry list, as the two Corvette Racing entries were joined by single entries from the Luc Alphand Adventures and PSI-Motorsport teams. However, the Corvettes could not equate their increased numbers into a GT1 class win, as Corvette Racing finished second in class, one lap behind the class-winning Aston Martin DBR9 entered by Aston Martin Racing.
* 2009 Corvette will officially leave the GT1 class. In August, Corvette Racing will officially debut their GT2 class entry at the Mid-Ohio ALMS race. The new GT2 car has body work inspired by the ZR1 Corvette.
