The Alfa Romeo 158/159, also known as the Alfetta, is a Grand Prix racing car produced by Italian manufacturer Alfa Romeo. It is one of the most successful racing cars ever; 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 World Championship of Drivers.

Jean-Pierre Wimille was a French racing driver and a member of the French Resistance during World War II. He was a two-time victor of the 24 Hours of Le Mans, winning in 1937 and 1939. He is generally regarded as one of the best French drivers of his era.
