1935 Alfa Romeo 6C 2300

Aerodinamica Spider

This elegant Aerodynamica Spider, known as the Aerospider, was a clandestine project built to win high-speed races. It is a one-off vehicle that has mid-engine placement, a central driving position, and an aerodynamic body meant to cheat the wind.

The project was spear-headed by Vittorio Jano, Alfa Romeo's chief engineer. Alfa Romeo had been a dominate force on the race track of Europe, but competition was coming from all angles. Auto Union had their mid-engine Type A 'Silver Arrow' and Daimler-Benz had their DOHC, supercharged straight-eight engine. Italy's national pride was on the line, and Jano was under pressure to answer. Jano had partners and financers in this project - brothers Gino and Oscar Jankovits of Fiume, Italy.

Development time was limited which meant Jano was unable to experiment with an all-new chassis layout. Instead, Jano focused on developing more power and placing the engine in a front-engined single-seater. Not putting all his eggs in one basket, Jano made a clandestine deal with the Jankovits brothers for a mid-engined sports racer to be made off-shore.

Jano provided Jankovits with Alfa Romeo parts and his expertise. Jankovits built, tested, and developed the vehicle in Fiume. Chassis number 700315, a 6C 2300 chassis, was shipped to Fiume. The engine bay was large enough to house a V12, but instead was given a six-cylinder engine modified with triple Weber 36 D04 carburetors.

Development of the car continued over several years, until Jano was fired from Alfa in 1937, just prior to the car being finished. This meant that an chance to fit a new V12 vanished. The Jankovits kept the Aerospider and had it registered for street use. The car still wears the original Fiume license plates.

To make the car more suitable to road use, the car was given a large windscreen, bumpers and turn signals. In 1946 Jankovits used the aerodynamic racer to break through the communistic border from Yugoslavia to Italy. They were free but short on money, so they sold their prototype to an Anglo-American soldier.

This Alfa Romeo was rediscovered in England in 1967. It went back to Italy in 2002 and in 2008, the car was restored to its original purpose of a high-speed racer.

The 2.3-liter version of Vittorio Jano's engine was a continuation of excellence and perfection. The 1500 was the first increment, and it truly created recognition for the Italian based manufacturer. The 1750 and 1900 soon followed, then came the 2300 which offered just over 70 horsepower initially. Its construction was very similar to its predecessors, utilizing two overhead camshafts actuating two valves for each cylinder. It was formed using a cast-iron block and light-alloy head and mated to a four-speed gearbox with drum brakes on all four corners.

The first car to house the 2300 engine was the 63 2300 which made its inaugural debut at the 1934 Milan Motorshow. The body was courtesy of Castagna in four-door saloon configuration. A short-wheelbase Gran Turismo version soon followed, as did a higher compression version of the engine offering nearly 100 horsepower. These sporty versions were called the Pescara model and only sixty examples would ever be produced. The long wheelbase versions were called the Turismo's, the shorter Gran Turismos were known as the Pescara's. Within a few years, they would simply be known as the SWB and LWB for 'short' and 'long' wheelbase respectively.

Time brings about improvement, and very little time transpired before a 'B' version was introduced. In 1935 the 6C 2300B was introduced which brought new changes to the suspension and chassis, and mild improvements to the already potent powerplant. The suspension was independent in both the front and rear with swing axles in the rear and wishbones in the front.

In 1937 a Pescara emerged from the Mille Miglia with a class victory; in its honor the Pescara's name was changed to MM.

Production of the 2300 continued until 1939 when it was replaced by the 6C 2500 which would remain in production, except during war time, until 1952.

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 engine's cubic-centimeter displacement size.

The engine was a version of Vittorio Jano designed a 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 a 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 wartime. 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 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 lightweight, bodies were capable of speeds in excess of 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 this one of the finest Alfa Romeos ever produced.
