The FSO Polonez is a motor vehicle that was developed in Poland in collaboration with Fiat and produced by Fabryka Samochodów Osobowych from 1978 to 2002. It was based on the Polski Fiat 125p platform with a new hatchback design by Zbigniew Watson, Walter de Silva and Giorgetto Giugiaro. It was available in body styles that included two- and four-door compact-sized cars, station wagons, as well as commercial versions as pickup truck, cargo van, and ambulance. Production totaled more than one million units, excluding the pickup truck and van variants. The Polonez was marketed in other nations and was popular in its domestic market until Poland joined the European Union in 2004.
