When designers of the VGD, (Voiture à Grand Diffusion), imagined the future of the now desirable Citroën DS, there were no limits or boundaries in relation to what materials were to be implemented in their quest for more French quirkiness.
Among the ideas that whirled around in the head of André Lefebvre, the chief engineer who presided over this thoughtful the project, was to build an extremely modular car.
Citroën even designed the car with a low centre of gravity, where body panels were strategically positioned and therefore easily removed if and when that time became necessary. These body parts were even designed with lighter materials, allowing for more efficiency and aerodynamics.
The steel body elements, the aluminium hoods (initially the rear one), the Plexiglas rear window and the fibre-glass roof were superimposed on a steel frame of a certain thickness, necessary to give rigidity to the structure of the vehicle.
Each of these components was screwed and not welded to the body, which helped guarantee the rigidity of the assembly, while the rubber seals assisted the other elements when joining individual sections, lessening vibrations and resonator issues.
This unique formula set by Lefebvre in 1939 remained intact until the end of the production of the DS and was even inherited by other Citroën cars, such as AMI6 and the same 2CV, utilising the same characteristics for simplicity of construction and ease of repair.
