Also produced by other manufacturers including Seat (as pictured above), the 600 was Fiat’s first small car to go on sale after the Second World War.
At the time of their launch in 1961, both models were fitted with the Billancourt engine which had made its debut in their predecessor, the Renault 4CV.
The Ami was mechanically very similar to the Citroën 2CV, but since it was also larger and heavier it was given an expanded 602cc version of the 2CV’s air-cooled flat-twin engine.
When launched in 1976, the LN was essentially a three-door Peugeot 104 hatchback fitted with Citroën’s 602cc twin-cylinder engine.
Although it didn’t look like it, the Méhari open-topped utility vehicle was related to Citroën’s 2CV, Ami and Dyane saloons.
Later known as the fortwo, the original smart city car was offered with a variety of three-cylinder turbocharged petrol and diesel engines.
Fiat’s replacement for the Nuova 500, which we’ll come to shortly, was only ever fitted with an inline two-cylinder engine. Its size varied during the lifetime of the car, though, reaching 704cc in later years.
DKW, the forerunner of today’s Audi, was the world’s leading producer of motorcycles – and of two-stroke engines – by the time it ventured into car manufacture in the late 1920s.
The 600 was a larger, four-wheeled development of the Isetta bubble car which BMW began building in 1955.
