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.
This car won the Polyphony Digital Award at Pebble Beach in 2014, and will likely be included in Gran Turismo 6 or Gran Turismo 7.
