Brabus has to be one of the craziest tuning companies around. Just how crazy is it? The company has created this insane monster, the Brabus 850 6.0 Biturbo G63 Widestar. As its name would imply, the G63 Widestar packs an incredible turbocharged V8 engine that pumps out 838 hp and 1,069 lb-ft of torque. That's an astonishing bump of approximately 200 hp and 300 lb-ft over the 6.0-liter V12 found in the already zany Mercedes-AMG G65 AMG.

To create this ludicrous amount of power, Brabus has increased the original 5.5-liter V8 to 6.0 liters by boring out the cylinders and installing larger forged pistons. There's a lot of other engine work under the hood, but the standard turbos have been replaced by larger compressor units, while intake and charge air pipes have been fitted with special "gold heat reflection." For a deeper growl, the SUV has been fitted with a Brabus sport exhaust system with stainless steel dual-side tailpipes. Incredibly, the G63 Widestar can get to 62 mph in 4.0 seconds and is limited to a top speed of 162 mph. Look out for the Brabus 850 G63 Widestart at this year's Frankfurt Motor Show.
