The Fiat 500 is a city car produced by the Italian manufacturer Fiat between 1957 and 1975. Launched as the Nuova (new) 500 in July 1957, it was a cheap and practical town car.
Measuring only 2.97 metres (9 feet 9 inches) long, and originally powered by an appropriately sized 479 cc two-cylinder, air-cooled engine, the 500 redefined the term "small car" and is considered one of the first city cars. In 2007, the 50th anniversary of the Nuova 500's launch, Fiat launched another new 500, stylistically inspired by the 1957 Nuova 500 but considerably heavier and larger, featuring a front-mounted engine and front-wheel drive.
To meet the demands of the post-war market which called for economy cars, in 1949 a front engine, Fiat 500 was released, a 2-door coupe body with sun-roof, this was later complemented by an Estate (Station Wagon) version; both continued until 1954 before replaced by the all new, lighter body car with rear-engine, on the pattern of the Volkswagen Beetle, just like its bigger brother, the 1955 Fiat 600. Several car makers followed the now uncommon rear engine configuration at the time and were quite successful. The Neckar version manufactured in Heilbronn under a complicated deal involving NSU, was introduced in October 1961. In Upper Austria the firm of Steyr-Puch also produced cars based, by agreement, on the Fiat 500. Despite its diminutive size, the 500 proved to be an enormously practical and popular vehicle throughout Europe. Besides the two-door coupé, it was also available as the "Giardiniera" station wagon; this variant featured the standard engine laid on its side, the wheelbase lengthened by 10 cm (3.9 in) to provide a more convenient rear seat, a full-length sunroof, and larger brakes from the Fiat 600. Sports models were famously produced by Abarth, as well as by Giannini. An Austrian variant, produced by Steyr-Daimler-Puch, the 1957–1973 Steyr-Puch 500, had a motorcycle-derived Puch boxer twin motor, a sports model of which was the 1965–1969 Steyr-Puch 650 TR2. Production of the 500 ended in 1975, although its replacement, the Fiat 126, was launched two years earlier. The 126 was never as popular as its predecessor in Italy, but was enormously popular in the former Eastern Bloc countries, where it is famed for its mechanical durability and high fuel economy. The Fiat 500 has a Cx (aerodynamic resistance coefficient) of 0,38, a very good performance for its time.
