The Fiat 500, introduced in 1957, is a compact car inheriting the will of the pre-war Topolino. But even more importantly, it was a new car that pursued the very minimum of a functional passenger car. Certainly, there are many differences between the Topolino and the Fiat 500. Compared with the two-seat Topolino, the Fiat 500, though cramped, had seats for four adults. Furthermore, while the Topolino had a front engine/rear drive layout, the Fiat 500, with a full monocoque construction body, had a rear engine/rear drive layout.
