Together with his colleagues at Citroen Andre Lefebvre created the Traction Avant (1934) the TUB 1939 Citroens first front wheel drive utility van that was succeeded by the H and HY vans 1947 the Deux Chevaux (1948) and last but not least the DS (1955).
From 1923 to 1931 Lefebvre also designed several highly original and outstanding competition cars and record-breaking automobiles for Voisin. He even drove some these cars in races and record attempts. It is obvious that during his 16 years with Gabriel Voisin he was very much influenced by the ideas of this illustrious aviation pioneer and car manufacturer.
The experience gained during that period gave him the self-confidence to persuade his successive bosses at Citroen that his unorthodox approach to automobile design was what the company needed alone earns him a place of honor among the great automobile designers of the past century. The fact that most present-day cars still carry the DNA of his design philosophy makes him stand out above other automotive pioneers and innovators.
