You will not believe it, a Beetle can also swim. In the America of the fifties, one has made attempts to put the Beetle carefully on the water with a crane. Almost exactly half an hour, it persevered.
Another American has brought his Beetle landed in the lake even with a rope to the shore, where it plummeted then at approx. one meter water level. His wife on the passenger seat could be rescued.
Yet another Beetle been washed away with the flood half a kilometer. When it is recovered and one opens the doors, it is undamaged and dry inside. Already some have wondered why at the Beetle the doors close only slightly, if you open a window.
Of course, an amphibious vehicle is even more intense protect downward against water penetration. In addition, it needs a more stable, although hand-crafted trough, the like a boat protrudes upwards before the front axle. Problematic are all the openings. E.g. the of the front and rear axle, track rod and extension of the crankshaft.
Sometimes it goes so steep in the water that the passengers get up and the whole snout immerse. Then the ship propeller folded down and the engine drives to approximately 10 km/h via a closed chain drive, more slowly even against the current. With the steering wheel and the front wheels is steered.
The amphibious vehicle is a further development of the bucket car. Different from this it has a simple all-wheel drive, which is led to the front axle through the central tunnel. At least it should be able to return to land without exit into the water according to the will of the military contractors. Here it is in an inferior position with its low maximum speed compared to the country vehicles. And there are no doors. 03/10
