Because the Volkswagen 82 (Kubelwagen) proved extremely successful through the campaign in Poland, it had been essential to produce everincreasing amounts of this automobile. Later, Ferdinand Porsche developed an amphibian version of this vehicle, called the Schwimmwagen. The light weight of this car (about 1/2 ton) allowed crossing of muddy areas, since only two guys were enough to keep this vehicle going. For reconnaissance and liaison missions, water must be crossed often, which was impossible along with other cars.
