The mental Mercedes C63 AMG Coupe Black gets reviewed on public roads and gets a bit of sideways action too. The C63 AMG Coupe Black is powered by the same 5.5-liter V8 biturbo engine as the regular model, and it develops 517 hp and 620 Nm of torque. This means it can get from nought to 62 mph (100 km/h) in 4.2 seconds and that it can reach a top speed of more than 300 km/h. However, it's limited to a maximum of 250 km/h.
