The Citroën DS is a front-engine, front-wheel-drive executive car that was manufactured and marketed by the French company Citroën from 1955 to 1975 in sedan, wagon/estate and convertible body configurations across three series/generations.

Noted for its aerodynamic, futuristic body design and innovative technology, the DS set new standards in ride quality, handling, and braking — the latter as the first mass production car equipped with disc brakes.

Italian sculptor and industrial designer Flaminio Bertoni and the French aeronautical engineer André Lefèbvre styled and engineered the car, and Paul Magès developed the hydropneumatic self-levelling suspension.

Citroën sold 1,455,746 examples, including 1,330,755 manufactured at the manufacturer's Paris Quai de Javel (now Quai André-Citroën) production plant.

The DS placed third in the 1999 Car of the Century poll recognizing the world's most influential auto designs and was named the most beautiful car of all time by Classic & Sports Car magazine.
