The Mercedes SLS Rado twin-turbo by World Motorsports is one of the sickest, most powerful and most insane versions of the German super car ever built. It makes 850 horsepower, and, as it turned out, massive flames.

Here’s a video of the car on a dyno machine. The thing is a bloody flamethrower. That technician sitting in the boot – presumably to push the back-end down for grip – gets almost cooked:

The magnificent M156 6.2 liter AMG V8 in the World Motorsports Mercedes SLS Rado is fitted with a meaty twin-turbo system that makes 850 hp at 4 lbs of boost. The tuner is aiming at 10 lbs for the next stage, eyeing outputs of well over 1,000 horsepower. If this car here is any indication, the next one is going to come out of the workshop already on fire!
