Background
Fiat launched the 600 in 1955 to replace the ageing and no longer appealing 500 "Topolino", with the clear goal to satisfy a growing number of customers looking to buy a compact car that was still capable of seating 4 adults.
The project, helmed by Dante Giacosa, the father of both the Topolino and the iconic Nuova 500, was rather ambitious despite the modest resources available to Fiat at the time: Vittorio Valletta, then president of the carmaker, wanted a simple yet not too spartan people's car that was also cheap and yet not boring to drive in order to take advantage of the automotive revolution. Unlike the Topolino, the Fiat 600 was initially equipped with fairly innovative 4 cylinder, 633cc engine with a cast iron block and an intake manifold that was part of the engine's head own casting. Another innovation was the rear mounted heat exchanger, a little feat that helped Fiat maximize the car's front cargo space. The Fiat 600 also feature front, transverse mounted leafsprings that doubled as an anti-roll bar, a successful solution later found on many of the automaker's models. However, the most important technical innovation, and a first for Fiat, was the adoption of an unibody chassis with a rear mounted engine.
