The Mercedes CLS63 AMG is already a beauty by itself. However, tuner Carlsson pushed it beyond in its kit called the CK 63 RS.
The performance changes made by the tuner were actually launched in IAA in Frankfurt. The 649HP and 900Nm torque upgrade premiered then, however, they are now altered its interior, by making it red which makes a great impact to how it looks because of the striking contrast to its white exterior paint.
The kit is available in other colors, of course, depending on the customer’s taste. So if you want orange or yellow green it might be doable.
