This time I have filmed a very brutal Mercedes-Benz CLS63S AMG by LA Performance. The ECU is done by RRahmani performance, fitted with racing filters, full BRABUS exhaust and catless downpipes! It produces now a whopping 912HP! You will hear some loud revs, accelerations and drag racing. It did a drag race of 1000 meters with a rolling start of 50 km/h. Best Vmax: 289,50 km/h. I hope you will enjoy the video.Liked the video?
