In 1937, Michelin, which recently bought Citroën, decided to launch a small car that would satisfy a new clientele, that of paid vacation (introduced in 1936), which would thus have the opportunity to travel at a lower cost. Note that Volkswagen had conceived the same idea in 1936 ... The specifications stipulated the following conditions: 4 seats, 50 kg of luggage, 3 speeds, no more than 3 liters per 100 kilometers, etc. We know the rest: serial production from 1948 to 1990, number of vehicles sold: more than five million. Between the popular 2 Chevaux and the Citroën Traction, then the DS, there was no mid-range vehicle. At the end of the 1950s, a new project was launched: the AM (M for mid-range). It is entrusted to Flaminio Bertoni, who had already worked on the Traction Avant and the DS. It was to be a vehicle with a maximum length of 4 meters, three volumes, the DS and 2 CV being two volumes. To keep as much space as possible in the trunk, and since the bosses did not want to increase the wheelbase of the 2 CV, Bertoni found an ingenious solution: invert the rear window, and thus offer more room to the rear passengers. This ingenious system was not a creation of Citroën: the Ford Anglia had already used this method in 1959, as well as large American sedans such as the Ford Mercury or certain Lincolns. The 435 cc engine fitted to the 2 Horses increased to 602 cc, to compensate for the weight gain. The Ami 6 met with great success, owing to greater comfort than its little sister while keeping its robust and reliable character. The Ami 6 was built in France but also in Forest, Belgium. In 1969, the AMI 6 gave way to AMI.
