Here’s a rundown of the most important cars in Citroen’s early hydro-history.
15-6H (1954) Fitted with full hydropneumatic suspension to the rear, this last-of-the-line Traction Avant model was a test-bed vehicle for the DS of 1955.
DS (1955) Lightweight panels hung on a monocoque structure, FWD and ‘intelligent’ suspension with featherlight steering, clutch, gearchange and brakes.
GS/A (1970) In a world of cart sprung family cars, GS/A offered aerodynamics, disc brakes all-round and smooth flat-four air cooled power. Produced until 1986.
SM (1970) Citroën snapped up Maserati in 1968 and this was the result. Peugeot took over and killed it in ‘75, Citroën going bankrupt having overspent on tech. CX (1974) Developed entirely in the wind tunnel, the CX combined FWD and transverse engine with groundbreaking ergonomic dash and speed sensitive steering.
