The resulting Fiat 600 was one of the great success stories of the twentieth century, with some 2.7 million cars produced.
The mixed-use station wagon, called 600 Multipla (All Service), was introduced in 1956. The idea was to multiply the serviceability of the 600 for both family motoring and business use.
The multi-place seating was very flexible through a combination of folding seats. Three versions were available:
* The 4/5 seater had bench seats front and rear that folded to make a bed.
* The 6-seater had a front bench and four individual seats that folded completely flat into the floor to make a roomy load platform.
* The Taxi version had a single seat and luggage platform in front, separate folding seats in the middle, and a bench seat in back, together with a division.
Differences from the sedan included, besides the bodywork, an auxiliary radiator up front, wishbone front suspension, different gear ratios, worm and roller steering, slightly larger fuel tank, and interior lamps.
