Sold from 1955 to 1975, the DS was decades ahead of its time. Its curious to me why its many innovations did not appear in American cars a lot sooner.
* A hydro-pneumatic suspension. By creating a
sphere of liquid with compressible gas above it, the ride was such that many still regard this to be the best riding car ever built. The spheres used for the suspension also controlled the brakes.
* The roof is made of fiberglass to lower the center of gravity and save weight.
* The DS introduced swiveling headlights that turn with input from the steering wheel.
* Citroën had been using radial tires since 1948, while American cars were still using inferior 'bias ply' tires into the 1970s!
