CMN 20 hp Torpedo

The CMN 20 HP Torpedo, introduced in the immediate aftermath of the First World War, is a representative example of early Italian motorcar production during the transitional period between artisanal construction and emerging industrial standardization. Manufactured by Costruzioni Meccaniche Nazionali, a Milan-based firm established in 1919 through the acquisition of the assets of De Vecchi & C., the model reflects the technical norms and formal tendencies of the late 1910s and early 1920s. Though operational for only a brief period, CMN’s output contributed to the foundation of Italy’s postwar automotive identity. The 20 HP designation corresponds to a four-cylinder side-valve petrol engine of approximately 2.3 litres in displacement. The engine was coupled to a three-speed manual gearbox, transmitting power to the rear axle. The chassis employed a ladder-type frame with semi-elliptical leaf springs mounted longitudinally at both axles. Braking was confined to the rear wheels, operated by mechanical linkage—a standard arrangement for the period. The mechanical configuration prioritized durability and serviceability, attributes considered essential for automobiles in an era of limited infrastructure and variable fuel quality. The Torpedo coachwork by Carrozzeria Emilia featured an open four-door layout, with a folding canvas top and upright windscreen. Characterized by its long bonnet and modest rear overhang, the design was derived from French stylistic conventions of the 1910s, adapted for Italian clientele. The body was mounted over a steel ladder chassis and often finished with minimal ornamentation. Interior appointments were basic, reflecting the model’s utilitarian orientation rather than aspirational luxury. While CMN’s presence in the marketplace was modest, the company holds historical significance for having employed Enzo Ferrari as a racing driver. Ferrari participated in events such as the 1919 Targa Florio driving a CMN 15/20 HP, a closely related mechanical platform. Though no factory-sponsored racing effort was maintained for the 20 HP, its engineering principles were consistent with the requirements of endurance trials and long-distance motoring. Production of the CMN 20 HP ceased by 1923 following the company’s acquisition by Piaggio. Surviving examples of the model are exceedingly rare. Chassis documentation is fragmentary, and known specimens are held in private collections, occasionally exhibited in vintage motoring events. The CMN 20 HP Torpedo remains a rare artifact from the formative years of the Italian motor industry.
