New C63 Black Series AMG coupe spyphotos - M157 twin turbo V8 rumors continue
The previous C63 Black Series spyphotos
we showed you last month were of the sedan. This brought into question if they were focusing on the sedan or if the coupe had been abandoned. It is quite clear now Mercedes is working on Black Series versions of both. Photographers did look under the hood and it seems the 571 horsepower performance package version of the M157 twin turbo 5.5 liter V8 may make it to production. If so, game over, we bow in respect, and sign us up.
