Carlsson here has made a fantastic work on this C-class which I didn't wate it from this tuner company.Anyway, this car is very fast and very sport.Without any turbo's or kompressor's this tuner company has managed to make its engine of 3200cc to produce 420hp!!(something like formula1!)The seats have been changed and been replaced by other racing ones even and the back seats!Many aerodynamic assistance etc.And even its atmospheric engine that produces lot's of power for it's capacity can catch a very high top speed(295km/h!!) where normally these types of engines lose some kilometers of their topspeed.
Don’t believe what your eyes are telling you. All they show is limitation. Look with your understanding.
A stupid man's report of what a clever man says can never be accurate, because he unconsciously translates what he hears into something he can understand.
