A look back at the 1939 Alfa Romeo 6C 2500 Sport Berlinetta
Although still well known today, the Milan-based Alfa Romeo was one of the most popular automobile manufacturers of the 1920s and 1930s. With thousands of full-time artisans and mechanics dedicated to building just a few cars, Alfa Romeo designed supercars that represented the pinnacle of artistic, automotive and technological prowess. Unfortunately, in the end, the company ran into financial problems, which led to its downsizing and absorption by Fiat. Although several auto giants developed their high-performance cars at the time, none could match the performance standards set by the 6C 2500. When it made its debut at the Milan Auto Show in 1925 , the car has set new standards in many categories.
The 6C was perhaps the greatest automotive design of the era and the one that ultimately skyrocketed Alfa Romeo’s reputation, and here’s a detailed look at this legendary vehicle.
The beautiful and light construction
Debuting with its showcase at the Milan Auto Show in 1925, the original Berlinetta (6C 1500) set new standards for light, high-performance road cars of that era. The chassis was fitted with independent front suspension and the torsion bar was independent of the rear suspension for superior handling and comfort. The 6C’s brakes, large drums with aluminum cooling fins narrowed around the cast iron drums, were extremely efficient for the time.
Like the box-section frame and independent suspension, the brakes also helped make the 6C a performance-oriented automobile with a wider, heavier body. The rugged design, superior suspension, big brakes and powerful engine worked perfectly with the lightweight body like Touring’s patented Superleggera Berlinetta.
Covered headlights inside the voluptuously rounded front fender flank the tall, curved Alfa Romeo grille. The long hood and the steeply angled windscreen are a clear reminder of the company’s success in competition. The low roof flowed smoothly into a tapered fastback rear deck above the sultry shaped rear fenders with wheel gaiters. Despite being a 4-seater, the 6C 2500 Sport Berlinetta seemed fit to be on the starting line of the Mille Miglia or Le Mans.
The attractive tobacco-colored leather interior also featured a lumbar support adjustment hidden under a Touring-patented flap and was possibly the oldest of its kind. In addition, this majestic car rode on 18-inch wheels of reasonable size for optimum elevation. These features enhanced the exceptional performance provided by the magnificent engine of this Italian beauty.
The roaring powerhouse
The 6C was the latest and fastest of Alfa’s famous 6-cylinder cars, capable of reaching high speeds due to its lighter body, increased displacement and improved fuel delivery. The car was fitted with a 2.5-liter twin overhead cam inline 6-cylinder engine, one of the most powerful machines of the time. The 6C was also fitted with a 4-speed manual transmission system to give the driver more control over the vehicle. This transmission generated 96 hp at 4,600 rpm and allowed a top speed of 100 mph. These numbers were among the highest at the time.
The optional 6C 2500 SuperSport engine was fitted with an additional third carburetor and an 8: 1 compression ratio, meaning the pistons received more fuel to burn and generated more power. This improved the performance of the 2500 Berlinetta, which was almost on par with the flagship 8C 2900.
The design features and ingenious power mechanics certainly gave the car its legendary history, although only 13 of them were produced.
The heritage of the berlinetta
The Alfa Romeo 6C has established itself as one of the most representative models, both ancient and modern post-war vehicles, among racing and touring cars. The Alfa Romeo 6C lasted almost 25 years, accompanying vehicles from the 1920s to the 1950s. In the early 1920s, Vittorio Jano was commissioned to create a lightweight, high-performance vehicle to replace the RL and RM models. The car was presented in April 1925 at the Salone dell’Automobile di Milano under the name 6C 1500, as the 2-liter class was replaced by the 1.5-liter class for the 1926 racing season.
The company released the 6C 2300 after numerous revisions and in 1934 won the top three places at 24 Ore di Pescara. This car was later called ‘the king of the hill’ in Mille Miglia racing history from 1935 to 1938, and the various 6C models competed with real teams, driven by some of the most popular racers in the world. time. The Alfa Romeo 6C 2300 was later replaced by the 6C 2500, which was the last version of the series before WWII. After the war, when production resumed, many special versions of the vehicle were built which proved to be strong competitors in racing.
The development of the 6C engine ended with the final version of 2.5 liters, the production of which continued until 1953, retaining the fundamental design of Vittorio Jano.
The 6C 2500 can now only be seen at prestigious auto shows, auctions or museums. Although owning the car is not the easiest task due to its rarity, many collectors offer their Berlinettas for auction at specialist auctions like the prestigious RM Sotheby.
