Two teams of Corvettes have just been added, completing the field for the 2011 GT1 World Championship. InRacing.com reported March 19th that the four Corvettes were added to the race later than other cars because they are being used as replacements for the four cars and teams that pulled out of the race at the end of last season.

At the end of 2010, both Maserati teams withdrew, creating an opening for Corvettes to take their places on the grid. According to World GT1 rules, sportscar brands must be represented in a pair of racing teams. This means that four of each sportscar that is represented must race in the GT1 World Championship. The Corvettes join a field of Nissans, Fords, Lamborghinis and Aston Martins, representing a race field of 20 cars.

The two teams of Corvettes will be racing under the banners Exim Bank Team China and DKR Engineering. Teams Hegersport and Vitaphone Racing will not be represented at the race this year due to team drop-outs, although the latter is a GT1 champion team. Mike Hezemans, a regular GT1 racer, will be driving one of the Corvettes for at least a couple rounds.

Swapping out Maseratis for Corvettes isn’t the only change for the 2011 GT1 season. Many changes have been made in the drivers on all teams except for team Aston Martin. Swish, Belgian and Munnich racing teams have moved away from the car brands they were previously associated with for the 2011 championship, creating a new field of championship contenders.
