Competition history

The Maserati 6C 34 is a 750 kg open-wheel Grand Prix race car, designed, developed and built by Maserati from 1934 to 1935. [5]

Racing history

The 6C 34 was equipped with an in-line six-cylinder engine that was 30 hp more powerful, and 13 kg lighter, compared to the eight-cylinder installed on the 8CM. [6]

Only five days after the completion of the engine tests on the dyno, the 6C 34 made its racing debut at the 1934 Italian Grand Prix where, due to brake problems, the car did not perform well. At the following Grand Prix, on the Masaryk Circuit, the 6C 34 driven by Tazio Nuvolari finished third, surpassed by the elusive Mercedes-Benz and Auto Union, but ahead of the Alfa Romeo P3.

In 1935 adjustments were made to the chassis to stiffen it, and new suspensions were tested, which were now independent wheels and with the Parisi system.

The experience of the 6C 34 in racing ended as a semi-official car for the Scuderia Subalpina, driven by Achille Varzi, Pietro Ghersi, and Eugenio Siena, achieving important placings but no victory.

Design

The ignition was single with a Spark or Bosch magnet. The feeding was forced with a Roots-type compressor and a Weber-type 55AS1 carburetor, the latter mounted upstream of the compressor itself. The distribution was with two valves per cylinder arranged in a 90 ° V, and a double overhead camshaft. Lubrication was forced with delivery and recovery pumps. The cooling system was a water circulation with centrifugal pumps. [7]

The engine was six cylinders in line and had a displacement of 3724.1 cm³. The bore and stroke were 84 and 112 mm respectively, while the compression ratio was 6.4:1. This engine produced a power of 270 hp at 5300 rpm.

The brakes were drum brakes on the wheels with hydraulic control, while the suspensions consisted of leaf springs, friction shock absorbers, and a stabilizer bar, subsequently implemented with independent wheels and with the Parisi system. The steering was a worm screw and toothed sector, while the transmission consisted of a four-speed gearbox plus reverse.

The bodywork was single-seater in aluminum, while the chassis was made up of two side members and cross members in steel profiles.

The “6C 34” reached a top speed of 250 km/h.

It used an intricate tubular space frame chassis, containing about 200 chro-moly steel tubes welded together, arranged triangular formation at high stress areas of the chassis, hence the nickname "Birdcage". This method of construction provided a more rigid and, at the same time, lighter chassis than other racing cars of the time.

The Alfa Romeo 6C name was used on road, race, and sports cars produced between 1927 and 1954 by Alfa Romeo; the "6C" name refers to the six cylinders of the car's straight-six engine. Bodies for these cars were made by coachbuilders such as James Young, Zagato, Touring Superleggera, Castagna, and Pinin Farina. Beginning in 1933 there was also a 6C version with an Alfa factory body, built in Portello. In the early 1920s Vittorio Jano received a commission to create a lightweight, high performance vehicle to replace the Giuseppe Merosi designed RL and RM models. The car was introduced in April 1925 at the Salone dell' Automobile di Milano as the 6C 1500. It was based on Alfa's P2 Grand Prix car, using a single overhead cam 1,487 cc in-line six-cylinder engine, producing 44 horsepower. In 1928 the 1500 Sport was presented, which was the first Alfa Romeo road car with double overhead camshafts.

The Maserati 4CL and its derived sister model the Maserati 4CLT are single-seat open-wheel Grand Prix racing cars that were designed and built by Maserati. The 4CL was introduced at the beginning of the 1939 season, as a rival to the Alfa Romeo 158 and various ERA models in the voiturette class of international Grand Prix motor racing. Although racing ceased during World War II, the 4CL was one of the front running models at the resumption of racing in the late 1940s. Experiments with two-stage supercharging and tubular chassis construction eventually led to the introduction of the revised 4CLT model in 1948. The 4CLT was steadily upgraded and updated over the following two years, resulting in the ultimate 4CLT/50 model, introduced for the inaugural year of the Formula One World Championship in 1950. In the immediate post-war period, and the first two years of the Formula One category, the 4CLT was the car of choice for many privateer entrants, leading to numerous examples being involved in most races during this period.
