The Alfa Romeo 158/159, also known as the Alfetta, is one of the most successful racing cars ever produced. The 158 and its derivative, the 159, took 47 wins from 54 Grands Prix entered. It was originally developed for the pre-World War II voiturette formula (1937) and has a 1.5 litre straight-8 supercharged engine. Following World War II, the car was eligible for the new Formula One introduced in 1947. In the hands of drivers such as Nino Farina, Juan-Manuel Fangio and Luigi Fagioli, it dominated the first two seasons of the Formula One World Championship.





Overview

The first version of this successful racing car, the 158, was made during 1937 and 1938. The main responsibility for engineering was given to Gioacchino Colombo.

The car's name refers to its 1.5 litre engine and eight cylinders. The voiturette class was for racing cars with 1.5 litre engines, standing in the same relation to the top 'Grand Prix' formula (usually for 3 litre engines) as the GP2 series does to Formula One today. Alfa's 3 litre racing cars in 1938 and 1939 were the Tipo 308, 312 and 316.

The 158 debuted with the works Alfa Corse team at the Coppa Ciano Junior in August 1938 at Livorno, Italy, where Emilio Villoresi took the car's first victory. At that time the 1479 cc engine produced around 200 bhp at 7000 rpm with the help of a single-stage Roots blower. More success came at the Coppa Acerbo, Coppa Ciano and Tripoli Grand Prix in May 1940.

Soon World War II stopped development of the car for six years. After the war the engine was developed further to push out 254 bhp in 1946.

In 1947, the Alfetta became eligible for the newly-created Formula One. The new rules allowed 1500 cc supercharged and 4500 cc naturally aspirated engines. The 158 was modified again, this time to produce over 300 bhp and was denoted as Tipo 158/47. The car made a tragic debut in the 1948 Swiss Grand Prix where Achille Varzi lost control of his car and was killed. Another loss for the team came in practice for the 1949 Buenos Aires Grand Prix, where Jean-Pierre Wimille was killed in an accident (driving with Simca-Gordini).

The car won every race in which it competed during 1950; it was incredible that a car which had originated in 1938 was so victorious. The Alfa Romeo team included talented drivers such as Giuseppe Farina and Juan Manuel Fangio, the latter of whom later won the World Drivers' Championship five times.

At the end of the 1950 season, a further updated version known as the 159 was produced. This version had reworked rear suspension, the old swing axle was replaced with a De-Dion axle and the engine produced around 420 bhp at 9600 rpm. For their last World Championship race (until 1979), the 1951 Spanish Grand Prix, Alfa Romeo introduced a new evolution version known as the 159M, the "M" standing for Maggiorata ("improved").

The 1952 World Drivers' Championship was run to Formula Two regulations, so the 159 became obsolete.

The car's last Grand Prix win came in 1953 at Merano Grand Prix, Italy.
