The Citroën DS was first shown at the Paris Salon of 1955. In the first 15 minutes of the show Citroën had 743 signatures, and by the end of the first day over 12,000 orders were taken.
The DS was Citroën's replacement for the Traction Avant (i.e. Célestine) and was designed by the same man. Everything apart from the engine was new and innovative: the shape (naturally), the suspension (hydraulic and self levelling) the gearbox and clutch (also hydraulic) and they even managed to re-invent the wheel...
For some reason, this year Retromobile was celebrating the 1955 Salon and had a remarkable selection of DS's to drool over, including:
We quite like the DS. Not sure it is the best backup car for Célestine, but as a 1950s vision of what the 21st century should look like it's pretty spot on.
