It doesn't take a second glance to see this is a heavily beefed up version of the new C 63 AMG Coupe. Upon first impressions, there are those huge pumped out wheel arches front and back traditional to AMG Black Series cars. The front guards might also feature racing-style heat-extracting vents behind the front wheels, similar to the old CLK AMG Black, by the looks of the camouflaging.
Although this test car is covered in fairly extensive camouflaging, vast revisions are expected to have been made to the front bumper. It appears to include a sharp chin spoiler, visible by the pointy centre, air ducting for the front brakes and a large radiator scoop in the middle.
From the side we can see the Black Series version will be fitted with a big brake package incorporating cross-drilled rotors and huge multi-piston calipers clamping large diametre discs.
The Black Series is also said to feature a highly uprated suspension package over the standard C 63 AMG Coupe, with added chassis stiffening and suspension braces throughout.
Underneath the bonnet of the C 63 AMG Black is a bit of a mystery at this early stage. Speculation suggests it will boast an uprated - rather, an 'un-detuned' - version of the 6.2-litre V8 that comes with the standard C 63 (336kW). Output is expected to exceed the 500hp (373kW) mark.
AMG Black Series cars are not only about outright power, however. The car will also be much lighter than the standard AMG version, shedding weight by having its rear seats removed and the fitment of slimmer interior details and fundamentals such as lightweight carbon fibre front seats.
No word yet as to when this bad boy will hit the market, or indeed when it will be officially unveiled. We'll keep a close eye on it and keep you updated.
