In 1956/1957 Maserati put together this 150GT prototype from leftover racing parts. The two-seat cabriolet body was also totally unique and the only one of its type.
This Maserati likely started life as an A6G racecar that was later fitted with Maserati 300S components. In 1956 it was built up as a prototype using a two-liter version of the four-cylinder engine from the 150S.
Taking cues from the 4CTF single-seat race car, Vittorio Bellentani designed the 4-cylinder engine with advanced features such as dry-sump lubrication, an aluminum alloy block with cast iron liners and options such as a hemispherical combustion chamber with a 80º angled valves and twin-plug ignition.
The 150GT chassis was sent to Fantuzzi to be bodied in a style similar to the Pietro Frua A6G cabriolets. Unique to the design are accent dashes that run between the center of the grill and the front blinkers. Furthermore, the side exhaust and right-hand drive configuration hint at the car's earlier life as a racecar.
Maserati only made one copy of the 150GT before moving onto the production 3500GT. Sometimes this prototype roadster is referred to as a 1500GT which would make sense given the lineage.
In concours condition, the 150GT recently underwent a mechanical restoration by Steve Hart Racing. In 2013, Gooding & Co. will offer the sole 150 GT at their Scottsdale sale in Arizona with an estimate of over $3,000,000 USD.
