[1] The 1.5-litre straight-six was named A6 TR (Testa Riportata for its detachable cylinder head[2]), and was based on the pre-war Maserati 6CM and produced 65 hp (48 kW).

The acronyms identifying each model are interpreted as follows: "1500" or "2000" indicate the rounded up total engine displacement in cubic centimetres; while suffixes such as "53" denote the year of the type's introduction.

This cycle-winged racing version made its first competition appearance at Modena 1947 with Luigi Villoresi and Alberto Ascari, and won the 1948 Italian Championship with Giovanni Bracco at the wheel.

Development was started in 1941 by the Maserati brothers, but it was halted as priorities shifted to wartime production and was only completed after the war.

[8] The first chassis, bodied by Pinin Farina, debuted at the Geneva Salon International de l'Auto in March 1947.

This first prototype was a two-door, two-seat, three-window berlinetta with triple square portholes on its fully integrated front wings, a tapered cabin and futuristic hidden headlamps.

For production Pinin Farina toned down the prototype's design, switching to conventional headlamps; soon after a second side window was added.

A Pinin Farina Convertibile was shown at the 1948 Salone dell'automobile di Torino, and two were made; one car was also given a distinctive coupé Panoramica body by Zagato in 1949, featuring an extended greenhouse.

Suspension was by double wishbones at the front and solid axle at the rear, with Houdaille hydraulic dampers and coil springs on all four corners.

[9] 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.

In 1955, Guglielmo Dei bought two more chassis, numbers 2109 and 2110, and employed Carrozzeria Frua to create two open-top models.

After a two-year hiatus at the 1954 Mondial de l'Automobile in Paris Maserati launched a new grand tourer, the A6G 2000 Gran Turismo—commonly known as A6G/54 to distinguish it from its predecessor.

Fed by three twin-choke Weber DCO carburettors it put out 150 hp (110 kW; 148 bhp) at 6000 rpm, which gave these cars a top speed between 195 and 210 km/h (121 and 130 mph).
