Mercedes C63 AMG Black Series by Renntech

"Real-world performance is all about torque, not so much about a peak horsepower number at very high rpm," explains Feyhl. "It can be very easy to build high rpm horsepower, but to get instant throttle response and mid-range acceleration it is more difficult, and this is where customers really want to feel that improvement." The car got also a new suspension kit which lowered it even more and added carbon fiber elements like a new front splitter and rear diffuser to manage the underbody airflow.

With the new customization programme the car is capable to hit 100 km/h in less than 4 seconds while the top speed is over 300 km/h.
