Fiat 600 at the Josefuv Dul Car Show, Liberecky kraj, Bohemia(CZ), 2015

When I first saw this car, I assumed it was a Fiat 500, but Fiat, in fact, also built a Fiat 600, which looked very similar, as this one does. The 600 actually predated the second generation of the 500 (which is the one everyone knows) by 2 years. The 500 was actually a scaled-down 600 intended as one of the world's first "city cars" designed to be as small as possible.

The Fiat 600, like the 500, always came with an air-cooled I-4 engine, in a rear/rear layout. The engine was longitudinally mounted behind the rear axle, showing the influence of the Volkswagen Beetle in the design process. Displacement of the engine varied, but was always less than a liter, being available, in various years, at 633cc, 767cc, and 843cc displacement. Predictably, it was a very slow car for 1955, with a top speed of only 95Km/h (59 m.p.h.), much slower than every variant of the Volkswagen Beetle, as well as most other economy cars at the time. For that matter, it was slower than a Ford Model A. Its other numbers are similarly bad, except for that its small size does make it ideal of a city.

As this photo illustrates, the Fiat 600 does have enough of a fan following to be found in preservation, possibly being due to it's somewhat unusual design (although, as I said, the better-known Fiat 500 is based on it).
