Today GM debuted their new unified GT racer, the ZR1 based C6R GT2.

Testing will be done at the remaining six races this year in order to get the bugs worked out for next year.  For this year, the cars will use LS7 based 6.0L’s but next year they will have to work with only 5.5L of displacement and run on E85R racing ethanol fuel.

“The global movement toward a single GT class will allow us to compete head-to-head with more marketplace competitors while increasing both the production content of the Corvette C6.R race cars and the relevance of racing to our customers. This is a step that positions Corvette for the future of production-based sports car racing worldwide, and a move that is perfectly aligned with GM’s marketing and business objectives in racing,” said Mark Kent, GM Racing manager.

The first race for the new car will be the Acura Sports Car Challenge at Mid-Ohio this coming Saturday, August 8. It will be televised on ABC at 2:30pm Sunday, August 9.
