1939 Alfa Romeo 6C 2500 SS

The Alfa Romeo 6C 2500 was available as both a road-going and competition car. Alfa Romeo created the rolling chassis and commissioned coachbuilders to create the competition bodies. The competition cars were fitted with a six-cylinder engine tuned to produce around 120 horsepower. They were given a modified suspension and often clothed in lightweight aluminum coachwork. Three were sent to Carrozzeria Touring in 1939 to be prepared for the grueling Mille Miglia race.

The cars were ready but the race was cancelled due to a tragic accident. Instead, the three cars made their inaugural racing debut at the Tobruk-Tripoli race where they finished in first, second and fourth place.

For the LeMans race, a special berlinetta body was prepared that had a strong resemblance to its larger 8C 2900B LeMans sibling which had run the race in the year prior. The 8C would have won the race, as it was leading by over 100 miles when a broken valve meant its hopes for glory were prematurely sidelined.

The preparations for the 6C included an aerodynamic, and curvaceous body, plus the addition of a larger fuel tank. Raymond Sommer and Prince Bira were tasked with driving the berlinetta during the race. As had happened the year prior, the cars potential was limited by its reliability issues. Even after hours of repair work in the pits, the car was unable to finish the race.

It was entered in the 1950 Mille Miglia but with disappointing results.

The Alfa Romeo 6C 2500 was introduced near the end of the 1930's. The 6C name was derived from the engine size, an inline-six while the 2500 represented the engines cubic-centimeter displacement size.

The engine was a version of Vittorio Jano designed six-cylinder engine. The 6C was available in a plethora of body styles and wheelbases and was produced during two different times in history. Most of the coachwork was handled by Touring of Italy or by Pinin Farina. The body styles ranged from coupes and convertible to four-seater salon. In 1939 Alfa Romeo introduced the SS version, a short-wheelbase model, dubbed 'SS' for Super Sport, that had a high-compression 6C engine rated at 105 horsepower. It was the top-of-the line 6C model that married style and performance together to create the perfect road-going vehicle.

World War II had interrupted production for many automobile manufacturers. During this time many switched their efforts to support the war, such as building engines for marine and aircraft or by producing vehicles that were suitable for war time. When Alfa Romeo resumed production, their vehicles were similar to those they had offered in 1939. The main difference was that Alfa Romeo now bodied the cars themselves rather than providing the rolling chassis for custom coachbuilders to body. The designs had become standard but they were still based on sketches and designs produced by coachbuilders such as Pinin Farina and Touring. Pinin Farina built the exclusive bodies such as the Cabriolet. These vehicles were elegant and stylish and had a price tag that matched. Touring built the Coupes which became known as the Villa d'Este in 1949 after winning the famous Concours d'Elegance Villa d'Este. When outfitted with the Superleggera, meaning light weight, bodies they were capable of speed of over 100 mph.

The engines were similar to the Jano designed six-cylinder power plant, capable of producing 110 horsepower. Independent suspension was installed to soften the ride while improving performance and handling characteristics. A four-speed manual transmission was similar to the one used prior to the onset of the war.

The history of the Alfa Romeo 6C 2500 automobiles are extensive. The various designs and body-styles matched with their mechanical capabilities make these one of the finest Alfa Romeos ever produced.
