The Alfa Romeo 158/159, also known as the Alfetta (Little Alfa in Italian

, it dominated the first two seasons of the World Championship of Drivers.

Overview

The first version of this successful racing car, the 158, was made during 1937/1938. The main responsibility for engineering was given to Gioacchino Colombo.[3]

The car's name refers to its 1.5-litre engine and eight cylinders.[4] 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 Formula Two does to Formula One today. Alfa's 3-litre racing cars in 1938 and 1939 were the Tipo 308, 312 and 316.

Alfa Romeo 158

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 1479.56  cc (58.0 x 70.0 mm) engine produced around 200 bhp (150 kW) at 7000 rpm.[5] 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.[6] 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 (189 kW) in 1946.

In 1947, the Alfetta was put back into service. 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 (220 kW) and was denoted as Tipo 158/47. The car made a tragic debut in the 1948

Simca-Gordini).[7]

In 1950, the 158 was eligible for the new World Championship of Drivers. The car won every race in which it competed during that first season of Formula One; it was incredible that a car which had originated in 1938 was so victorious, most likely because all the other constructors (as few as there were) had less money to build and develop their cars and the Alfa had so much development time. The Alfa Romeo team included talented drivers such as Giuseppe "Nino" Farina and Juan Manuel Fangio, the latter of whom later won the World Drivers' Championship five times.

At the end of the

Monza, Alfa Romeo introduced a new evolution version known as the 159M, the "M" standing for Maggiorata ("enlarged").[11]

After an unsuccessful bid by Alfa Romeo to obtain government assistance to meet development costs, the team announced their retirement from Grand Prix racing at the end of 1951 (leaving the development of the 2.5-litre

FIA that all Grand Prix races counting towards the World Championship of Drivers in 1952 and 1953 would be for cars complying with Formula Two rather than Formula One.[12]

The car's last Grand Prix win came in 1953 at Merano Grand Prix, Italy.[4]
