Technically the C63 uses the M156 engine while the SLS uses the M159 so no, not the same engine. Compared to the M156, the M159 engine includes an all-new intake system, reworked valve train and camshafts, the use of flow-optimised tubular steel headers and dethrottling of the exhaust system. The engine also utilizes a dry-sump lubrication system to lower the center of gravity of the car. I'm nitpicking lol
