What Does the Patent Describe?
The patent, filed by Mercedes-Benz Group AG, outlines a control system for an off-road vehicle designed to navigate bodies of water. It's not about turning an SUV into a speedboat, but rather enabling it to enter the water, remain stable while floating,
and successfully exit back onto land. The core of the invention involves detachable buoyancy modules made of foam or inflatable materials that would be installed within the vehicle's four wheel arches to help it float. The patent suggests these could be stored in the spare tire area and inflated with an onboard compressor when needed, meaning the vehicle wouldn't be permanently amphibious.
How Would It Steer and Move?
This is where the concept gets particularly clever. Instead of propellers, the system would use the vehicle's own wheels for propulsion and steering. The patent details how an adaptive suspension could lower the wheels deeper into the water to act like rudders. For an electric vehicle with four independent motors, like the new electric G-Class, the system could precisely control the torque sent to each wheel. It could even spin wheels in opposite directions to help steer the vehicle, counter a current, or assist in climbing onto a slippery bank. A control unit would manage this entire process, adjusting buoyancy and power distribution based on the vehicle's load and water conditions.
Is This For the G-Class?
While the patent doesn't name a specific model, speculation immediately turned to the iconic G-Class, especially the new electric G 580 with EQ Technology. This model already has the sophisticated architecture that would make such a system feasible, including four individually controlled electric motors and advanced suspension. The existing G-Class is already known for its impressive water-fording capabilities, but this patent describes a true floating or swimming operation, not just wading. This isn't the first time Mercedes has explored such ideas; another patent from late 2025 also described a floating vehicle, suggesting a consistent direction of engineering thought.
From Patent to Production: A Reality Check
It is crucial to remember that a patent filing is not a promise of a future product. Automakers frequently patent innovative and sometimes wild ideas to protect their intellectual property, and many of these concepts never make it to the showroom floor. The documents confirm that, as of now, the system remains a concept and is not attached to any official production project. So, while the engineering is intriguing and aligns with Mercedes-Benz's reputation for pushing boundaries, a G-Class that you can take for a swim remains an exciting possibility rather than a confirmed vehicle on the horizon. It's a glimpse into the future of off-road capability, but one that is still firmly on the drawing board.
