Fiat 615 was a small light truck built by Fiat from 1951 to 1965, with a longer life as the Fiat 616 until 1978. It was created to bridge the gap between the common van and the larger trucks, offering a payload of about 1.55 tons. The truck came in flatbed, panel van, or chassis-cab versions and rode on a traditional ladder-frame chassis with a modern cab.
