The history of the Maserati A6G.CS begins after the company was taken over by the industrialist Adolfo Orsi and his son Omer in 1937. The Maserati brothers, who had run the company for a decade, retired in 1947 to found their own company, OSCA.
During this transitional phase, Omer Orsi took the lead at Maserati and commissioned the engineer Alberto Massimino to develop a new sports racing car. It was to be built upon the materials Ernesto Maserati had left behind. The result was an open, purist racing car that could be used both as a 2-liter Formula 2 car and as a sports car with fenders. Its simplicity, especially the single headlight in the middle of the grille, earned it the nicknames "Monofaro" (single headlight) and "Cyclops."
The new car retained the A6G prefix, which dates back to the first Maserati A6. The "G" originally stood for "ghisa" (cast iron), although the new engine block was now also equipped with dry cylinder liners and was partially made of aluminum instead of cast iron. Later, the letters "C" for Corsa (race) and "S" for Sport were added, leading to the model designation A6G.CS.
The heart of the A6G.CS was a 1986 cc six-cylinder twin-cam engine, designed by Alberto Massimino and further developed by Gioachino Colombo. This engine delivered an impressive 170 hp at 7300 rpm.
A special technical solution from Ernesto Maserati was the valve train with a single camshaft that opened the exhaust valves via rocker arms, while the intake valves were opened via tappets. This unconventional method was a favorite of Ernesto's, who later used a similar design in his first OSCA engines. A triple roller chain drove the camshaft from the crankshaft.
Initially, the engine was supplied with fuel via three horizontal Weber carburetors. Later, twin Weber carburetors were used, which assigned a separate venturi to each cylinder. The high compression of 11.0:1 was possible thanks to methanol-based racing fuel, which allowed for an output of 130 hp at 6000 rpm. The car had a four-speed gearbox, which, however, had weaknesses and led to failures in early races.
The Maserati A6G.CS was an important step for the company, proving its ambitions in racing. In 1953, the model was presented to a wide audience and served as a clear statement to the international competition, especially in America. The A6G.CS was extremely successful. It won its first race on the streets of Modena on September 28, 1947. With it, Roman Luigi Musso won many hill climbs in 1954 and was a class winner at the Giro di Sicilia and the Targa Florio. In total, 52 examples of the A6G.CS were produced by 1955 and sold to racing drivers in North and South America and Europe, who achieved numerous victories with them.
The "Monofaro" or "Cyclops" will be remembered as the car that successfully made the transition from the Maserati brothers' era to the Orsi family's control.
Unfortunately, very little is known about the history of this new build-or rather, recreation. The body, like the original, is made of aluminum. An Argentine vehicle registration (Título del Automotor) from January 15, 1973, exists, which states that the vehicle ("Fiat Sport / Maserati") from 1950 with chassis number 019594 (engine number 0041) was registered at that time to a certain Mario Adolfo Amisonio.
