CMN (Costruzioni Meccaniche Nazionali) was an Italian car manufacturer, active from 1919 to 1923, with production facilities in Milan and Pontedera.
CMN was founded in Milan by a group of financiers that took over the factories of the car manufacturer De Vecchi & C., in serious economic difficulty, but with highly trained and experienced workers. Among those workers also the talented motorist Luigi Marino, later founder of the automobile company Marino from Padova.
As it was used at the time, a company participation was offered to a famous pilot, Ugo Sivocci, in order to obtain good results and immediate notoriety.
This was the circumstance that allowed Enzo Ferrari to enter the world of motoring. In fact, after meeting a young, unemployed Ferrari in search of work in Milan, Sivocci offered him a job as a test driver and then as a pilot.
The debut in the automotive field took place with the participation in the Parma - Poggio di Berceto hillclimb and at the 1919 Targa Florio with two models of the "15/20 HP" model in sporting equipment, entrusted to Sivocci and Ferrari.
The following year, in 1920, CMN began having the cars built at Officine Toscane in Pontedera, which it later acquired, transferring the production site to Pontedera to refine the 2297 cm³ 4-cylinder engine with side valves.
In 1923 the CNM presented two new cars: the "25 HP", equipped with a 6-cylinder in-line engine of almost 3 liters of displacement, and the "Type 7", with a 4-cylinder engine of 1940 cm³ with overhead valves, capable of reaching a maximum speed of 125 km / h.
At the end of the same year the company decided to stop producing cars and sell the factory to Piaggio.
