At the beginning there was the Mercedes-Benz C63 AMG Coupe, a model that was developing 451 hp (457 PS). After that, the Stuttgart-based carmaker has introduced the AMG Performance package that was lifting the power to 480 hp (487 PS). 
If these two versions don’t fit with you behavior, the German carmaker brings it Black Series edition, a 510 hp (517 PS) version. In the end, Mercedes also offered two more optional packages for the C63 AMG Coupe Black Series, called Aerodynamics and Track. 
In short, this is the story of the latest Mercedes C63 AMG Coupe. The German tuning house Vath has decided that is not enough for this special model. They come with a new supercharger, a custom exhaust system and new software that take the power output up to 746 hp (756 PS). Thanks to these modifications, the German model can sprint from stand still to 100 km/h in 3.6 seconds, while the top speed is clocked at 350 km/h. 
The kit is priced at 49.310 Euros, excluding VAT. The German tuner also offers a new suspension kit that can lower the ride height between 20 – 65 mm, new 20 inch wheels, higher performance brakes and various interior trim options.
