Cigarette Racing and Mercedes-AMG joined forces to create this GT S inspired boat called the 50 Marouder GT S Concept racing boat. The car pulls its power from a 4.0-litre V8 engine but the boat gets two Mercury racing engine which allows this 15 m long rocket to hit a scary 217 km/h. The hull is finished in matte black with Solarbeam highlights and it looks rather serious next to it’s four-wheeled inspiration. Although it is called a concept, the power boat has been given a price tag of $1.2 million which means it is for sale. I bet someone will come along and buy both!
