It had a total weight of 3,100 kg (6,834 lb), and was available in versions stake or van bodywork, chassis and carrozable for transportation and as a tractocamioón.

At first the model had a new petrol engine with 1395 cc and 29 kW (39 hp) at 3800 rpm to 1400 Fiat, and had a manual 4-speed transmission.

Once in motion, the Fiat 615 was indeed 80 km/h (50 mph) fast, but with forced driving it had poor fuel efficiency.

The somewhat weaker beast of burden was, with its 1.1 liter and 28/30 PS (at 4400 rpm) a little lame, but it had fully loaded a ton to move less weight, so was more economical.

The export ran well at the beginning, missing, or half-hearted development left the Fiat 615 N (and especially its successor) over the years to become increasingly rare even in Italy.
