Cosmetic surgery? Far more than just that

The 402 N4X, conceived and developed by the famous engineer Jean Andreau in 1935, can still be seen at the Peugeot Museum in Sochaux. The other five units produced were all destroyed during the war, and the project as a whole failed mainly as a result of that terrible trauma, which began at the end of 1939. Peugeot, keen for its 402 to be able to match the technically (although certainly not stylistically) innovative Citroën Traction, had recruited mechanical engineering and aerodynamics specialist Andreau precisely because of his aeronautical background and the experiments he had done as director of the Crasson Aerodynamic Research Center.
