The first sketches of the VGD Project (Voiture à Grande Diffusion) date back to 1945. The DS 19 CITROËN will be presented at the 42nd Paris Motor Show on October 6, 1955. New materials: plastic, light alloys, and cutting-edge techniques: hydropneumatic suspension for 4 independent wheels, are put to the service of a revolutionary aesthetic, which will divide France in two: the "for" and the "against".
