Maserati A6 were various cars made by Maserati of Italy, named for Alfieri Maserati (one of the Maserati brothers, founders of Maserati) and for the straight-six engine.
The 1.5-litre straight-six was named A6 TR (Testa Riportata), and was based on the pre-war Maserati 6CM; 65 bhp (48 kW). It first appeared in the A6 Sport or Tipo 6CS/46, a barchetta prototype, developed by Ernesto Maserati and Alberto Massimino. This became the A6 1500 Pininfarina-designed two-door berlinetta, first shown at the 1947 Salon International de l'Auto in Geneva (59 made) and the spider shown at the 1948 Salone dell'automobile di Torino (2 made).
A 2-litre straight-six (120 bhp) was used in the A6 GCS two-seater, «G» denoting Ghisa, cast iron block, and «CS» denoting Corsa & Sports. Also called monofaro, the 580 kg single-seater and cycle-winged racing version first appeared at Modena 1947 by Luigi Villoresi and Alberto Ascari, and won the 1948 Italian Championship by Giovanni Bracco. Fifteen cars were made 1947-1953, of these being two-seaters (630 kg).
The A6G were a series of two-door coupe and spyders by Zagato, Pininfarina, Pietro Frua, Ghia, Bertone, Carrozzeria Allemano and Vignale. These had alloy engine blocks.
Maserati A6GCM (1951–53) were twelve 2-litre single-seater («M» for monoposto) racing cars (160-190 bhp), developed by Gioacchino Colombo and built by Medardo Fantuzzi. The A6 SSG (1953) was a GCM-revision pointing to the Maserati 250F. It won the 1953 Italian Grand Prix driven by Juan Manuel Fangio.
To compete in the World Sportscar Championship, the A6GCS/53 (1953–55) was developed (170 bhp), spyders initially designed by Colombo and refined by Medardo Fantuzzi and Celestino Fiandri. Fifty-two were made. An additional four berlinettas and one spider were designed by Pininfarina, their final design of a Maserati, on a commission by Rome dealer Guglielmo Dei who had acquired six chassises. Also, Vignale made one spider.
The 1954 Mondial de l'Automobile in Paris showed the A6GCS/54, which came in berlinetta, barchetta and spider versions (150 bhp), with designs by Pietro Frua, Ghia and Carrozzeria Allemano. It was also referred to as the A6G/2000 and 60 were made.
