The Alfa Romeo 900 commercial truck was produced from 1947 to 1954. As a line, the model was virtually identical to its successor, the Alfa Romeo 800, according to its page in Wikipedia.
The new truck had a 9,500cc, 128-hp six-cylinder diesel engine and four-speed transmission. In addition, the loading capacity was increased to 9 tons, and a three-axle version was also available.
By the mid-1950s, the Model 900 was updated and became known as the Model 950. The main difference between the two models is the small windows behind the front doors of the cab.
The 950 was in production until 1958. The 950 was replaced that year by the new Mille model.
Alfa Romeo 800
The Alfa Romeo 800 heavy truck was in production between 1940 and 1947. According to its Wikipedia military page, the Model 800 was first produced as a military version 800RE and after the war as a civilian version.
The military Model 800 was initially used only in the Italian Army (“Regio Esercito”). It was used mainly in North Africa, Russia and occupied France.
The 800 was equipped with a fuel-injected 8.7-liter diesel engine and could reach a top speed of 31 mph (50 kmh). There also were gas generator and gasoline models produced.
A half-track prototype version called the CSEM 800RE was made for the Italian army. The Centro Studi ed Esperienze della Motorizzazione was the Italian Army’s vehicle research and development organization.
Some of the 800RE models were also converted to the German Army as half-track Maultier trucks.
The 800 was replaced by the model 900.
