This time I have filmed a very brutal Mercedes-Benz CLS63S AMG by LA Performance. With updated ECU and racing filters, full BRABUS exhaust and catless downpipes it produces now 720HP! 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: 284.23 km/h. I hope you will enjoy the video.
