 The Chevrolet Corvette C5-R closed out an historic era on Saturday night wîth a GTS victory at Mazda Raceway Laguna Seca, a circuit in which the championship-winning team had never won. Ron Fellows and Johnny O'Connell took the class victory in their #3 Compuware Corvette C5-R, seconds ahead of teammates Oliver Gavin and Olivier Beretta in the #4 Corvette. The successful endurance sports car racing program closed out the Corvette C5 era wîth a notable 35th victory in 55 races. Corvette won every single American Le Mans Series event in 2004 as well as the 24 Hours of Le Mans.

 'It's a very special year when you can go undefeated,' said Doug Duchardt, GM Racing director. 'It's great for the team to finally win at Laguna Seca and this was an amazing effort from the beginning until the end. We're going to work very hard in the off season to continue wîth the Corvette C6-R in 2005.'

 The four-hour event started in sunny and warm conditions, but ended under hard rain and darkness. The #4 Corvette started from the pole position and held the lead for roughly three hours; a close race in the pits sent the #3 Corvette out in front wîth only an hour remaining. Johnny O'Connell was able to hold off Olivier Beretta under the gathering rain, and took the final checkered flag for the Corvette C5-R.
