Fiat's first real industrial vehicle, the 615N, produced from 1952 to 1960, combined a sturdy frame with side members to the diesel engines used for the 1400 and the Campagnola. The vehicle had rounded shapes and a front that could recall that of the 500C and the city buses 400 and 411. In 1951 a petrol version was released. In Yugoslavia it was produced under the Zastava brand, before the 620 evolution.
