Marengo is a model name that Italian car maker Fiat has given to the van derivatives of its mid-size cars, beginning with the "Fiat 131 Marengo" in 1979 and continuing with the Regata, Tempra, and Marea. The Marengo light commercial vehicle derivatives only have two seats and have only been equipped with diesel engines. The nameplate was retired in 2001 and succeeded by the van version of the Fiat Stilo Multiwagon. Fiat has a tradition of naming their commercial vehicle derivatives differently from the cars upon which they are based, compare with the Fiorino and the Penny.
The first version was introduced in 1979 and was a three-door panel van version of the Fiat 131. Unlike the succeeding models it had unique bodywork, as no other three-door estate version of the 131 was marketed. It was actually sold as the "131 Marengo".
The second generation was presented alongside with the new Fiat Regata Weekend upon which it was based. As with its successors, the side windows in the rear were blacked out. Unlike the Regata, with its four engine options, the Marengo was only available with a 65 PS (48 kW), 1,929 cc diesel engine. A strict two-seater it has a cargo capacity of 430 kg (948 lb).
