Ignoring the strict rules laid down by the occupying power, Citroen engineers continue to work in secrecy during the war, modifying the design of the 2CV and developing the van that is to succeed the TUB: the Type H.

After the war, the French government introduces strict planning measures. The rationing of raw materials delays the launch of the two models above. The 11 BL goes back into production in 1945, followed by the 15 Six in 1946 and the 11B in 1948.

Production of the Type H starts in 1948, followed by the 2CV in 1949. Pierre Boulanger, who was always very much involved in all the design office projects, dies in an accident just one month after presenting the prototype of the 2CV Van at the Paris Motor Show in October 1950.

Throughout its 41 years of existence, the 2CV remains a record beater, leading a life packed with travel and adventure. Its main quality is to provide users with the car they need. It is, in turn, a rural car, an urban car, a removal lorry, a racing car, a family car, a second-hand car for students and young couples, and and an expedition vehicle for driving around the world. Moreover, the 2CV forms the basis for many derived models and utility versions.

More than any other car, the 2CV symbolises France in other countries, and deserves the title of historical monument for the automotive industry in France.
