Introduced in 1954, the Romeo van was the first mass-produced Italian front-wheel drive vehicle and a rare case of the application of a twin-shaft petrol engine to a commercial vehicle; the engine was mounted on the Giulietta sedan a year later. A two-stroke diesel with a supercharger was also available. The second series (Romeo 2) was marketed from 1957 to 1967, again with a twin shaft but with a ZF gearbox in place of the Alfa Romeo one. In Spain, Fadisa produced a Romeo with a 1600cc Perkins diesel engine. The Romeo was then replaced by the F11 and F12 with the Giulia engine.
