AMS from Italy was founded in 1969 by engineer Tancredi Simonetti, former working at ATS. Drawing on the expertise of ex-ATS workers, Simonetti focused on building high-performance two-seater and single-seater race cars. ATS was created in 1961 by Carlo Chiti, Romolo Tavoni and Gotto Bizzarrini. They started in buildings in Casalecchio di Reno and moved to Sasso Marconi, both in the Bologna province. Simonetti also created Scuderia Autoracing, used for the more commercial aspects, because some of his clients were gentleman drivers.
The AMS company became known for models like the AMS 277, which competed successfully in national competitions during the 1970s. AMS stood out for its technical innovation, quality construction, and aerodynamic designs, continuing to have a strong presence in Italian motorsport until the late 1970s.
Statistics state that they built around 90 cars. Among their professional drivers were Mauro Nesti, Ezzio Baribbi and Luigi Moreshi.
In 1976, research began on a two-seater for 1.3-, 1.6-, and 2.0-liter engines all suitable for the Tipo 277 chassis. This model featured a larger chassis (particularly in terms of wheelbase and track width) and a particularly aggressive aerodynamic package. The bodywork had a striking wedge-shaped profile, with a pronounced, pointed front overhang, high, downforce-generating sides, a cockpit recessed into the upper profile, and a large, free-standing rear spoiler. Fuel supply was provided via a prominent periscope behind the driver.
During the 1977 season, the AMS 277 actively participated in all national races, particularly those counting towards the World Championship for Makes. Competition there was fiercest, with the various Chevrons, Lolas, Marches, and other makes scoring 15 World Championship points at the end of the season. In the months leading up to the 1978 season, several significant updates were made to the Tipo 277, particularly in the areas of suspension and aerodynamics. At the same time, a new two-liter engine became available, built entirely by AMS. This engine was designed by engineer Simonetti in collaboration with his colleague Minghetti. It was a four-cylinder engine with 16 valves, a double overhead camshaft (DOHC), a belt drive, and mechanical fuel injection. As in the previous season, AMS limited its participation to Italian races, a decision partly due to the ongoing crisis in the sector and the resulting decline in sales. Official participation in Italian championship events also declined.
In 1979, AMS withdrew from racing and focused primarily on building new cars and providing upgrade and support services. The company diversified into sectors unrelated to motorsports. The sporting successes of the Tipo 277 continued unabated, thanks in particular to Francesco Cerulli Irelli, Vittorio Bernasconi, Girolamo Caci, Odoardo Govoni, Mario Nardari and Roberto Villa.
