The Fiat 600 (, ) is a rear-engine, water-cooled city car, manufactured and marketed by Fiat from 1955 to 1969 — offered in two-door fastback sedan and four-door Multipla mini MPV body styles. Measuring only long, its all-new design was the first unibody and rear-engined Fiat, and was priced at 590,000 lire (the equivalent of about €8,680 or US$9,440 in 2023). The total number produced from 1955 to 1969 at the Mirafiori plant in Turin was 2,695,197. The 1955 Fiat 600 formed the blueprint for the 2nd generation "Nuova" (New) 500, launched two years later – which was even smaller, at and, although rounder, largely copied the 600s layout and shape. Later, the 600 also formed the platform for the larger 850 saloon, launched in 1964, which coexisted with the 600 in Fiats line-up for five years, until the 600 was cancelled. During the 1950s, '60s, '70s and '80s, many units were built in countries such as Spain (as SEAT 600), where it became the icon of the Spanish miracle and where it was nicknamed Seiscientos; Argentina, where it was nicknamed Fitito (a diminutive of FIAT) and former Yugoslavia where it was nicknamed Fića or Fićo (pronounced [fee-cha] and [fee-cho] respectively). Much of the 1974's SEAT / Fiat 133 platform can even be traced back to the Fiat 600. Development Codenamed Progetto 100 ("Project 100"), the Fiat 600 mirrored the layout of the Volkswagen Beetle and Renault 4CV of its era. Aimed at being an economical but capable vehicle, its design parameters stipulated a weight of around 450 kg with the ability to carry 4 people and luggage with a cruising speed of no less than 85 km/h. A total of 5 prototypes were built between 1952 and 1954, which all differed from each other. Chassis number 000001 with engine number 000002 is believed to be the sole remaining example, according to a recent report by Quattroruote's "Ruoteclassiche" vintage division. It was powered by an innovative single-cam V2-cylinder engine designed to simplify maintenance and did not feature a clutch pedal. At the official launch in 1955, FIAT engineer, Dante Giacosa declared that the aim had been to create something new, both in the interest of progress and simplification. This prototype, however, did not become the chosen design. Characteristics The car had hydraulic drum brakes on all four wheels. Suspension was a single double-mounted leafspring—which acts as a stabilizer—between the front
