In 1927 the 1500cc single overhead cam six-cylinder engine was introduced to the Alfa Romeo stable, and over the next five years would undergo many modifications, updates, and improvements. The following year the engine had been given two overhead cams and an increase in power. By 1929, the displacement had been increased to 1752cc where it would remain through 1932. In total, fewer than 400 examples of the 67 1750 SS and GS cars were constructed.

The heroic capabilities of the engine were first seen in 1982 when Giusepee Campari won the grueling Mille Milgia with the first of the 6C 1500 supercharged Zagato Spyders. From there, Alfa Romeo's domination in the sports car racing scene would continue to escalate. Campari would repeat his victory in the Mille Miglia in 1930, this time with a 6C 1750 Zagato Spyder driven in the 2000cc class. Pirola and Guidotti won their 1500cc class in a 6C 1500. Seven of the top ten places that year were Alfa Romeos.

Alfa Romeo's success in competition continued with their 8C 2300. In 1950 an Alfa Romeo Tipo 159 Zagato bodied car won the first Grand Prix World Championship.

This 1931 Alfa Romeo 6C 1750 Zagato Spyder is equipped with the superchanged engine that provided 85 horsepower at 4400 rpm. It is from the fifth series of production and wears coachwork by Zagato. It was first registered on August 10th of 1931 in the village of Saint Varent in Southwest France to Baron Phillipe de Gunzbourg. It was given the registration number 493 XL1.

It is believed that Baron used this car in motor racing with several notable successes. On June 5th of 1932 he won the 2000cc class at the La Mothe Ste Heraye hill climb and another class victory on June 12th at the Pumoyen hill climb.

In 1933 the Baron co-drove an 8C 2300 Alfa Romeo to second place at the 24 Hours of LeMans with Luigi Chinetti.

de Gunzbourg owned this car until September of 1935 when it was registered in the department of Basses Pyrenees with registration number 5906 NM2. On May 14th of 1940, ownership passed to the aircraft manufacturing company Hydravions F.B.A. of Argenteuil near Paris and registered 5922YC2.

On June 5th of 1944, the car was purchased by Victor Polledri, a friend of Luigi Chinetti. It was given the Paris registration number 3081RN4. The car would remain in his posession until the late 1960s when it was sold to M. Barriere who used it sparingly until his death. Upon his death, the car passed to his son. While in his son's care, the engine was rebuilt and the Zagato coachwork was stripped to bare metal. Little was done after that; it was sold in the early 1980s to its last owner. The car has been stored, in unrestored condition since that time.

In 2007 it was offered for sale at the Gooding & Company auction held in Pebble Beach, California where it was estimated to sell for $900,000 - $1,200,000. It is rare that an unmolested supercharged Alfa Romeo Zagato Spyder 6C 1750 comes to market. As the gavel fell for the third and final time, the lot had been sold for the sum of $946,000 including buyer's premium.
