Photographers have recently spotted a sedan version of Mercedes C63 AMG Black Series. The pictured 4 door prototype - spied while lapping at the Nurburgring - shows a more aggressive look thanks to the big deep front spoiler and the wider wheel arches.
No official release date has been set for the model, which will probably use the same 6.3-litre V8 engine (delivering 517hp and 620Nm of torque) powering the C63 AMG Black Series. Gearbox and suspension are also expected to be shared with its coupe counterpart.
