Description

The Alfa Romeo 8C 2900 B Corto “Corsa” (commonly referred to as the 8C 2900 B Corsa) is one of the most legendary and revered racing cars of the 1930s. Designed as a competition-oriented version of the 8C 2900 B, this model was purpose-built to dominate endurance and road racing events. Combining Alfa Romeo’s cutting-edge engineering with uncompromising performance, the 8C 2900 B Corsa solidified its status as one of the greatest pre-war sports cars ever created.

At its core, the 8C 2900 B Corsa featured the same 2.9-liter straight-eight engine as other 8C models, designed by the renowned Vittorio Jano. This highly advanced powerplant utilized dual overhead camshafts and twin Roots-type superchargers, delivering an impressive output of around 220 to 240 horsepower, depending on the tuning. The engine was derived from Alfa Romeo’s Grand Prix cars, giving the Corsa variant exceptional performance for its time. Mated to a four-speed manual transmission, the car could achieve speeds in excess of 130 mph, a remarkable feat during the 1930s.

The 8C 2900 B Corsa was built on a short-wheelbase (Corto) chassis, which improved agility and responsiveness, making it ideal for competitive racing. The chassis was constructed using a lightweight tubular steel frame, ensuring structural rigidity while minimizing weight. The car was equipped with independent suspension on all four wheels—an advanced feature for the era—providing superior handling and ride quality. Hydraulic drum brakes on all corners ensured consistent stopping power, even under the demanding conditions of racing.

The bodywork of the 8C 2900 B Corsa was characterized by its lightweight, aerodynamic design. Carrozzeria Touring, known for its patented Superleggera (super lightweight) construction method, crafted the streamlined aluminum body. The car’s low, aggressive stance, long hood, and curvaceous fenders emphasized its purpose-built nature, while details like faired-in headlights and minimal ornamentation underscored its focus on performance over luxury.

The 8C 2900 B Corsa’s racing pedigree is legendary, with notable successes in events such as the Mille Miglia and the 24 Hours of Le Mans. One of its most famous victories came in the 1938 Mille Miglia, where an 8C 2900 B driven by Clemente Biondetti and Aldo Stefani claimed first place with an average speed of over 84 mph—a record for the time. The car’s combination of speed, reliability, and handling made it virtually unbeatable in its class, earning it the nickname “the fastest sports car in the world.”

While the Corsa variant was primarily intended for racing, it retained some elements of refinement, showcasing Alfa Romeo’s ability to blend performance with elegance. Only a limited number of 8C 2900 B Corsa models were ever produced, making it an exceptionally rare and valuable automobile.

Today, the Alfa Romeo 8C 2900 B Corsa is celebrated as one of the most significant and collectible pre-war cars in automotive history. With its groundbreaking engineering, stunning design, and illustrious racing achievements, it holds a special place in the hearts of enthusiasts and collectors. Examples of the 8C 2900 B Corsa are highly sought after and often command record-breaking prices at auctions, while their appearances at prestigious concours events continue to captivate audiences worldwide.
