The Maserati A6 was named for Alfieri Maserati (the 'A'), one of the Maserati brothers who founded the company, and the straight-six engine (the '6'). Introduced at the 1947 Geneva Auto Show and built through 1956, it was built atop an advanced tube-frame chassis, powered by a single-overhead camshaft engine, and the original A6/1500 coupe wore coachwork designed and built by Carrozzeria Pinin Farina. Praised for its excellent road-holding, modern styling, and potent engine, the definitive version of the model appeared in 1948 and ushered in a new era for Maserati, as it was the company's first true production car. A total of 61 examples of the original A6/1500 were built and all but two received aluminum coachwork by Pinin Farina.
Maserati A6 GCS
The Maserati A6 GCS, 'G' for Ghisa (cast-iron block) and 'CS' for Corsa & Sprots, was a two-seater, cycle-winged sporting racing car powered by a 2.0-liter straight-six engine offering 120 horsepower. It was raced at Modena in 1947 by Luigi Villoresi and Alberto Ascari, and won the 1948 Italian Championship by Giovanni Bracco. It remained in production through 1953 with a total of fifteen examples built.
Maserati A6G 2000
The 2000 version of the A6G arrived in 1950 and received an enlarged 1954.3cc (119.3 cubic-inch) engine with a bore of 72 mm and a stroke of 80mm. With triple carburetors, the engine produced as much as 100 horsepower and gave the A6G 2000 a top speed in excess of 100 mph. Semi-elliptic leaf springs were added to the rear axle and nine of the sixteen cars wore coachwork by Pinin Farina. One example wore a design by Giovanni Michelotti and was bodied by Vignale as a coupe, and Frua built five convertibles and one coupe. Pinin Farina ceased collaborating with Maserati in 1952 as its workload with Ferrari increased.
Maserati A6GCS/53
The A6GCS evolved into the A6GCS/53, and was developed by Gioacchino Colombo and inspired by a Formula Two design used in the A6GCM. The 'CS' in the car's name continued to represent 'Corsa Sport' and its tubular chassis generally made by Gilco. The chassis design used a fairly classic design with a triangular front axle and a rigid rear axle with leaf springs.
Alberto Massimino left Maserati in 1953 for Stanguellini, and his departure was filled by Gioacchino Colombo, known for his work at Alfa Romeo, and the future designer of the V12 Ferrari engine that took his name. He perfected the development of the twin-cam, twin-ignition six-cylinder engine adapted for the sports version, and in 'Mille Miglia' guise, the engine developed 170 horsepower. It had seven main bearings by Vandervell, a short-stroke architecture, a nitrided crankshaft, a cast aluminum block with cast-iron cylinder liners, aluminum pistons, dual-plug ignition, and twin overhead camshafts.
The Maserati A6GCS/53 was built between 1953 and 1955 with 52 examples built including 48 as open spyders. Four of them were Berlinettas bodied by Pinin Farina and many of the spyders were clothed by Carrozzeria Fantuzzi.
Marketed as the 'Maserati Sport 2000,' these lightweight cars enjoyed successful hillclimb and road race events, with a class victory in 1953 at the Mille Miglia and third overall in 1954.
Maserati A6G/54 2000
The Maserati A6G 200 Gran Turismo, known as the A6G/54, was introduced in 1954 at the Mondial de l'Automobile in Paris. The double overhead camshaft inline six-cylinder engine had a bore of 76.5mm and stroke of 72mm, resulting in a total displacement size of 1,985.626 cc (121.2 CID). Fed by three twin-choke Weber DCO carburetors, the engine offered 150 horsepower at 6,000 RPM and was paired with a four-speed manual gearbox. Dual ignition was added in 1956 and boosted output to 160 bhp. Hydraulic drum brakes provided the stopping power. The front suspension was independent with wishbones, coil springs, and Houdaille hydraulic shock absorbers. The live rear axle was suspended by quarter-elliptical leaf springs with Houdaille hydraulic shock absorbers.
Carrozzeria Allemano bodied twenty-one coupes to a design penned by Michelotti. Frua bodied six coupes and twelve Gran Sport Spyders, and Zagato created a single spyder and twenty competition-oriented fastbacks. The Zagato Spider, chassis number 2101, was displayed at the Geneva Auto Show in 1955.
Produced between 1954 to 1956, a total of sixty examples of the Maserati A6G/54 2000 were built. Derived directly from competition, they helped Maserati transition from the race track to the road. The A6G/54 was followed in 1957 by the 3500 GT, the first comfortable Maserati Gran Turismo.
