Originally only available with the same 2-door sedan body as used in Italy, two different 4-door versions also appeared in 1967. The very rare
corto (short) used the bodywork developed by
Francis Lombardi for the Fiat 850 "Lucciola", while the
largo (long) version used a floorpan lengthened by 15 cm and bodywork developed specifically by Carrocerías Costa for SEAT. At the 1971 Paris Motor Salon, the 850
Especial Lujo (Special deLuxe) was presented, only available with the 4-door
largo body. Production ended in late 1974, having been replaced by the
SEAT 133, essentially an 850 rebodied in the style of the
127. Sedans and the standard coupé received 843 cc four-cylinder engines with either . After
Fiat 850 production ceased in Italy in 1972, the SEAT version was sold in European countries through Fiat dealers for a couple of years. These cars had a
Fiat badge which had "costruzione SEAT" underneath it. == SEAT 850 Sport ==
