Iso built the Autocarro, a commercial version with full-width rear axle. The Autocarro was offered in several body styles, a flatbed pickup, enclosed truck, a tilt-bed, or even a fire engine, although some of these might not have been sold. The Autocarro was an extremely popular type of vehicle in Italy, and numerous manufacturers produced some variant of the type. Iso had previously produced a motorcycle-type Isocarro. The Iso Autocarro was larger than most, with its four-wheel layout, conventional rear axle with differential and leaf springs, and a large tubular frame. It was good for a 500 kg (1,100 lb) load. The name Isetta Autocarro was also used. It is thought that more than 4,000 Autocarros were built.
