The Fiat 500 Topolino (Italian: mouse) is an Italian passenger car of the interwar, World War II, and early postwar era. The first copies of this car appeared in 1936, and serial production lasted from 1936 to 1955. During this period, about 520,000 examples of this car were created. The drive was provided by one engine with a volume of 0.6 liters and a power of 13 hp. The first Fiat 500 Topolino cars were introduced in 1936 for the civilian market. The car was a two-seater with a very low curb weight (only 535 kilograms in the first batch!) and small dimensions. Acquisition and operating costs were also relatively low. Even before 1939, the license for its production was acquired by the French Simca plant and the German NSU. At the beginning of the Second World War, many of these cars were mobilized and served as staff cars for officers of the Italian and German armed forces, especially during the campaign in North Africa in 1940-1943. Serial production of the car continued until 1955, and after the Second World War two improved versions were introduced: the Fiat 500B and the Fiat 500C.
