The Fiat 500, commonly known as "Topolino", is an Italian city car produced and manufactured by Fiat from 1936 to 1955. The name "Topolino" is Italian and translates literally as "little mouse" in English, but is also the Italian name for Mickey Mouse. The Topolino was one of the smallest cars in the world at the time of its production. Launched in 1936, three models were produced until 1955, all with only minor mechanical and cosmetic changes. It was equipped... with a 569 cc four-cylinder, side-valve, water-cooled engine mounted in front of the front axle, (later an overhead valve motor) and so was a full-scale car rather than a cyclecar. The radiator was located behind the engine which made possible a lowered aerodynamic nose profile at a time when competitors had a flat, nearly vertical grille. The shape of the car's front allowed exceptional forward visibility. Rear suspension initially used quarter-elliptic rear springs, but buyers frequently squeezed four or five people into the nominally two-seater car, and in later models the chassis was extended at the rear to allow for more robust semi-elliptic springs.
