How did Volkswagen originate?

Literally translated Volkswagen = Peoples Car (an affordable vehicle). The "Beetle" was designed pre WW2 to be this "peoples car".

It had a "bolt on chassis" and this enabled the floorpan to be utilised for military purpose by fixing a different body onto it.

Thus the german army staff car - Kubelwagen - was in place.

And of course, the Feuhrer also commissioned the Autobahn - the first multi lane highway in the world.

Oh how he was slated then - but in fairness, he did have some ideas way ahead of his time.
