.40-60

The ALFA 40/60 HP is a road car and race car made by Italian car manufacturer ALFA (later to become Alfa Romeo). This model was made between 1913 and 1922 and was designed by Giuseppe Merosi, as were all other Alfas at that time. The 40/60 HP has a 6082 cc straight-four engine with overhead valves, which produced 70 PS (51 kW) and its top speed was 125 km/h (78 mph). The 40-60 HP Corsa racing version had 73 PS (54 kW) and a top speed of 137 km/h (85 mph), and it also won its own category in the Parma-Berceto race.

In 1914 the milanese count Marco Ricotti commissioned to Carrozzeria Castagna the ALFA 40/60 HP Aerodinamica (also known as Siluro Ricotti), a prototype model which could reach 139 km/h (86 mph) top speed. A replica of that car was created in the 1970s, and now it is shown in the Alfa Romeo Historical Museum.
40/60 HP production and development was interrupted by the First World War, but resumed briefly afterwards. The 40-60 HP Corsa now had 82 PS (60 kW) and a top speed of around 150 km/h (93 mph). Giuseppe Campari won the 1920 and 1921 races at Mugello with this car.
