If you thought the legendary German tuning house BRABUS only specialized in turning Mercedes-Benz G-Wagons into menacing, high-horsepower land missiles, it's time to look toward the water.In a groundbreaking new collaboration with luxury boat builder Sunreef Yachts, the performance brand has just unveiled the BRABUS Ultima 55. As showcased in a sleek new promotional video making the rounds across YouTube and TikTok, this isn't your standard weekend cruiser—it is a 55-foot floating supercar designed to fly right over the waves.The core appeal of the Ultima 55 is its breathtaking combination of catamaran stability and monohull agility, mixed with classic BRABUS aggression.Image Credit: https://www.brabus.comAdvertisementAdvertisementTo ensure the boat earns its badge, Sunreef equipped the 55-footer with twin six-cylinder engines that churn out a combined 1,450 horsepower. That immense power allows the luxury vessel to comfortably cruise past the 40-knot mark. But raw speed isn't the only trick up its sleeve.The Ultima 55 is equipped with a sophisticated hydrofoil system that actively lifts the hull above the water's surface at high speeds. This drastically reduces drag, eliminates uncomfortable listing, and provides passengers with the sensation that they are literally gliding above the ocean.Carbon Fiber EverythingVisually, the boat is unmistakably BRABUS. The striking Graphite Black hull is absolutely dripping in custom carbon-fiber components, from the illuminated roof pillars and front wings to an aggressive rear spoiler that looks like it was ripped straight off a GT3 race car.Folding side platforms can mechanically extend the yacht's width to nearly 25 feet, creating a massive waterside lounge complete with an electric barbecue, wet bar, and low-maintenance Esthec decking.Image Credit: https://www.brabus.comAdvertisementAdvertisementBelow deck, the bespoke interior offers customizable accommodations for up to six guests, featuring the same ultra-premium leather treatments you'd expect to find inside a BRABUS-tuned street car.Of course, claiming the title of "the hypercar of the sea" comes with a hypercar price tag. The BRABUS Ultima 55 starts at an eye-watering $3.7 million, proving that bringing the track to the open ocean doesn't come cheap.
