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.
In 1929 the 6C 1750 was created as a replacement for the aging 6C 1500. The name, 6C 1750, was a combination of the six-cylinder engine and the 1752 cc engine displacement. The 1750 continued the strong racing legacy Alfa Romeo had established with their P2 Grand Prix car and the 1500. The design for the Sport editions were simply yet sophisticated. They used a light frame coupled with a small inline-six cylinder supercharged engine capable of producing nearly 100 horsepower.
The 1750 was created in 1929 and produced until 1933, during this time nearly 2500 examples were created. There were six series each achieving a higher level of sophistication over the prior series. As was the case with many manufacturers at the time, Alfa Romeo supplied the rolling chassis and commissioned coachbuilders such as Zagato, Touring, Stablimenti Farina, Castagna, and James Young to finish the body. The result was a wide range of specifications and creativity.
The design was handled by Vittorio Jano, an individual Enzo Ferrari, an employee of Alfa Romeo, had been able to lure from Fiat. Jano had been tasked with designing the 6C 1500 which had been powered by a six-cylinder engine. He was then tasked with designing the 6C 1750 which was debuted at the 1929 Rome Motorshow. It shared many similarities with its predecessor; the biggest difference being an enlarged engine. Because of the larger engine it was capable of being outfitted with larger, heavier bodies.
The first version of the 1750 was the Turismo. The second version was the Sport which sat atop a shorter wheelbase and was given an improved engine. The most powerful and competitive versions of the 1750 was the Super Sport or Gran Sport. In this form they were often campaigned by the factory and privateers in a plethora of sporting events. They were equipped with supercharged engines and sat atop a short wheelbase. Most of the 360 examples received coachwork courtesy of Zagato, mainly because of the lightweight design. Only 44 examples of the sixth series Gran Sport were produced. The Gran Sport was successfully campaigned at events like the Mille Miglia, Targa Florio, and Tourist Trophy where it emerged victorious.
In 1931 the 8C 2300 replaced the Gran Sport. The 1750 Gran Sport is one of the finest sporting examples of its time. The 1750 continued Alfa Romeo's reputation for fun-to-drive vehicles that were competitive and durable.
