The Citroën CX is an executive car produced by the French automaker Citroën from 1974 to 1991. Citroën sold nearly 1.2 million CXs during its 16 years of production. The CX was voted European Car of the Year in 1975. The name CX is the French equivalent abbreviation of Cd for drag coefficient in English, drawing attention to the car's aerodynamic styling, which was uncommon in 1974.
It is considered by some enthusiasts as the last "real Citroën" before Peugeot took control of the company in 1976. The CX was also the final successful model of the "big Citroën" era, which began in 1934.
Available models were a four-door fastback, a station wagon (shooting brake, or estate car), and a long-wheelbase model built on the estate chassis. The CX employed Citroën's unique hydropneumatic self-leveling suspension system.
