Brabus really know how to take an already fast car and make it completely mental. Well they have taken the 503 horsepower Mercedes-AMG C63 S and gave a boat load of more power to allow it to top out at 320 km/h. They added some newly developed turbochargers featuring a larger compressor unit, a special core assembly with reinforced axial bearings, a reprogrammed ECU and a sports stainless-steel exhaust with actively controlled butterfly valves. That is good for 641 horses and 820 Nm of torque. Thanks to this improvement, 0 to 100km/h is dealt with in just 3.7 seconds. To make it look like it goes faster, there is a carbon aero and styling kit available in matte and mirror-polished finishes. This includes a front apron, rear spoiler, rear diffuser and mirror caps, with Brabus also offering plenty of interior customization options such as unique upholstery and aluminum trims and accents. We are very likely to see this car at the Geneva Motor Show.
