The 2011 C6.R uses a naturally aspirated, production-based 5.5-liter (336 CI) small-block V-8. Designated LS5.5R, the naturally aspirated powerplant is based on the Corvette Z06's 7.0-liter LS7 engine and is built with a production cast-aluminum cylinder block.
The reduction in displacement to meet the GT class regulations was achieved by shortening the crankshaft stroke and reducing the cylinder bore diameter. In accordance with the regulations, the race engines have two 28.8mm diameter intake air restrictors. The LS5.5R engines are equipped with dry-sump oiling systems, CNC-ported aluminum cylinder heads with titanium intake and exhaust valves, and sequential electronic port fuel injection. The race engines use E85 ethanol racing fuel in the ALMS and E10 fuel in Le Mans.
