No, Fiat came up with an improved version of it's pre-war Topolino, a small car built to the standards of a big one. After that came the 500. Very tiny but still a genuine 'real' car. It cannot compare to the Kabinenroller or the Heinkel and BMW Isetta. These were motorized scooters more or less, the Fiat 500 was conceived as a small car from the outset. May be the reason why it was built into the 1970's. As the 'wirtschaftwunder' progressed in WWII Germany, people traded their bubble cars in for Volkwagen Beetles.
