3. Citroën DS

Unveiled in 1955, the Citroën DS stunned the world with its revolutionary hydropneumatic suspension, which delivered a “magic carpet” ride never before seen in a production car. Its aerodynamic body and futuristic dashboard set new standards for automotive design.
However, the DS’s advanced tech and mechanical complexity made it a tough sell outside its native Europe, where mechanics were often baffled by its innovations. Despite this, the Citroën DS remains an icon of bold, forward-thinking engineering. BBC
