Citroën, one of the oldest automakers on the planet, has not sold a car in the US since 1974, the same year the Citroëm CX hit the market. The CX was designed to address the era's fuel-economy problem through aerodynamics and improve ride quality. It also featured advanced features such as a hydraulic steering system that automatically centered itself. Despite these features, the car was not well received in the U.S. due to poor timing and factors beyond the manufacturer's control. The car's quirky design and quirky features were noted throughout its lifetime, but not widely received acclaim. Despite OPEC's 1973 oil embargo, the market was not ready for an odd car with gas-sipping aspirations.
