The Fiat 850 is a small longitudinal-rear-engined rear wheel drive car which was produced between 1964 and 1973. Its technical design was an evolution of the very successful Fiat 600. The internal name for the Fiat 600 development project was "Project 100" and consequently, the internal Fiat codename for the 850 project was 100G (G for the Italian word "grande"—big). The engine of the 850 was based on that of the Fiat 600, but had its capacity increased to 843 cc. The 850 came in two versions: "normale" (standard) with 34 hp (25 kW) and "super" with 37 hp (28 kW). The maximum speed was approximately 125 km/h (78 mph). While it was not a large step forward in technical development, it possessed a certain charm with its large rolling eyes and its short tail, in which the engine sat. In 1968, Fiat revised the successful Spider and Coupé again and gave them an even stronger engine with 903 cc and 52 hp (39 kW). They were called Sport Spider and Sport Coupé. The Sport Spider body stayed essentially the same, but with a restyled front. The headlamps were moved forward slightly and the plastic covers were eliminated giving the car a "frogeye" look, and the original flush front turn indicators were replaced with units hung below the bumper.
