Brabus have launched their 850 version of the CLS Rocket, descried as “The World’s most powerful street-legal all-wheel-drive weapon”. Shmee150 has this exclusive footage from behind the scenes including hearing quite how this monster sounds!

The 850 has a twin-turbo V8 enlarged from the standard 5.5l to 5.9l producing 850hp with a limited 1,150Nm of torque. 0-100km/h is listed at just 3.1 seconds with a top speed of: very, very, very, very fast having been limited at 350km/h or 217mph.

The Brabus 850 CLS takes the 800 “Rocket” up one notch further in the numbers game, and the sound it makes just feels immense even at low revs.
