Maserati 150 GT

During the late 1950s, Maserati’s Modena workshops focused on both track and road development. The firm took the underpinnings of the competitive 150S, shortened and lightened the chassis, and commissioned a single handmade body to create the 150 GT prototype. This solitary example was never series-produced; it served as a technology demonstrator and an internal testbed.

Clad in classic spyder coachwork, the car measures 4 030 mm long yet only 1 480 mm wide, an unusually taut footprint that prioritises agility. The driver sits barely 1.2 m above ground, the compact 900 kg mass helping to maintain the 150S’s sharp reflexes while adding rudimentary touring comfort.

A 130 kW (approximately 175 bhp) four-cylinder sits amidships, breathing through twin Weber carburettors—the same powerplant that powered the 150S race car. Combined with the feather-like kerb weight, the 150 GT achieved an enviable kilogram-per-kilowatt ratio for its day.

Because only one chassis was completed and subsequently retained by the factory for decades, the 150 GT remains a footnote rather than a sales success. Nevertheless, it previews the mid-engine road-spider concept that would surface again in the Merak and Bora of the 1970s, and today the car is preserved as part of Maserati’s historic collection.
