German tuner VOS has just revealed one of the most extreme interpretations of the BMW M4 we've ever come across. Performance upgrades to the 3.0-liter twin-turbo straight-six has seen output increase to 550 hp and 523 lb-ft of torque, giving it a top speed of 193 mph. The chassis has been suitably upgraded with a Clubsport chassis and KW suspension, as well as a stainless-steel exhaust system with a middle silencer and rear muffler, bespoke Brembo brakes, and a set of 20-inch BBS alloys.

The only exterior mods are a set of carbon-fiber mirror caps and carbon rear diffuser. While the parts are available individually, the complete package comes in at over 27,000 Euros.
