Maserati 150 GT Spider Prototype

A one-of-a-kind, factory-built prototype, the 1957 Maserati 150 GT Spider originates from Maserati’s celebrated racing department, which was at its height during the mid-1950s. This unique Maserati was originally constructed as an A6GCS sports racing car and campaigned with success at important venues throughout the 1954 racing season. Having served Maserati well, the A6GCS was later modified, thus becoming the prototype for the celebrated 300 S model. Following its successful two-part career as a Maserati Works racing car, the chassis of the 300 S prototype was once more reworked for the development of an exclusive, new road car that showcased the firm’s engineering expertise. The result was this one-of-a-kind 150 GT Spider. Once completed, Maserati decided that the competition-based prototype was too expensive to be a feasible production car, and opted to move in a different direction with the mass-produced 3500 GT. Beautifully-restored and mechanically-rebuilt by marque specialist Steve Hart, this one-off prototype retains its original, matching-numbers engine, A6G/2000 gearbox, 250 F Grand Prix-type brakes and its elegant Fantuzzi coachwork. With a curb weight of only 1,900 pounds (860 kg) and 195 horsepower, the 150 GT offers performance that surpasses many 12-cylinder sports cars of the period. In summary, the 150 GT Spider is an extraordinary dual-purpose sports car with historical significance, beautiful continental styling and a fascinating history all of its own.
