Book excerpt: The Fiat 600, announced at the Geneva Show in 1955, was a four-seater within similar overall dimensions to the popular 500. The Multipla announced in 1956 replaced the earlier estates and accommodated not fewer than six people in a vehicle less than a foot longer than the basic 600. The third baby in the range was the slightly larger 850 with two delightful variants, the 850 coupT and the Bertone-styled 850 Spyder. Engine capacity and power were increased in 1969. The Multipla ceased production in 1966, the 600 in 1970 and the 850s in 1974.
