Giuseppe De Vecchi started to produce cars on his own through 1903. Ettore Strada, who joined De Vecchi, moved up to Milan and named the new company Milan Vecchi, Road & Co made up of workshops in a facility near Peschiera. The first model was the 10/12 HP fitted with a 4 cylinder motor bi-block, that it was produced until 1908, years in which Italy was in bad financial times. The company was renamed De Vecchi & Co.
Under the new corporate name the activity continued, in 1909, with the model from city 16/20 HP Tipo T of 2800 cm³ with patented pending, it did not carry an axle shaft bridge. Little after, came the Tipo B 20/30 HP of 4082 cm ³ with secondary transmission chains, in use for the models of greater power: the brakes, where the contracting jaws for the chains on the transmission.
In 1911 the De Vecchi used monobloc motors for the first time. In that year the range was completely redesigned. One motor, a 16/20 HP Tipo D (80 millimeter X 130 millimeter), was built to participate in an endurance race. Cars typically, were produced in two versions, with normal and lengthened chassis. The same tendency was towards motors for endurance races manifested in the new 20/30 HP (100 millimeter X 140 millimeter) of which in the 1911 they produced two versions: before, with monolateral valves with a monobloc; second an advance version of the biblock 25/35 HP of 1912.
In 1914 the models comprised of the 20/25 HP and F 25/35 HP; 1913, the Tipo C 25/35 5700 HP had been also been equipped with a 5700 of cm³ monoblock.

Driven by Ugo Sivocchi and a young Enzo Ferrari, the car placed 3rd and 6th at Targa Florio in 1913 and 2nd in1914.
In 1917 the automotive activity stopped and the corporate name was transformed into the Vecchi Mechanical workshops De S. With Italy entering the war, De Vecchi was constructing military trucks, four wheel drive artillery tractors and ambulances for the army. Also under the new name, the construction of aero engines was previewed and considered. The company was absorbed in late1919 by the CMN (National Mechanical Constructions), of Milan.
