Some of these mods will make your eyes water.
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.
