During my stay I have filmed this very big BRABUS 850 based on the Mercedes-AMG GLS63 XL. It has a 6.0 liter V8 BiTurbo engine that produce 850HP (stock: 585HP) and goes from 0-100 in 4.2 seconds for a car with a size of a house! This video shows you the start up, some accelerations and a night drive in Monaco! I hope you will enjoy the video!
