Citroën (French: [sitʁɔɛn] ) is a French automobile brand owned by Stellantis since 2021. The Automobiles Citroën manufacturing company was founded on 4 June 1919 by André Citroën. Peugeot acquired 89.95% share in Citroën in 1976, leading to the formation of PSA Peugeot Citroën, then known as PSA Group. Citroën's head office is located in the Stellantis Poissy Plant in Saint-Ouen-sur-Seine since 2021 (previously in Rueil-Malmaison) and its offices studies and research in Vélizy-Villacoublay, Poissy (CEMR), Carrières-sous-Poissy and Sochaux-Montbéliard.
In 1934, the firm established its reputation for innovative technology with the Traction Avant. This was the world's first car to be mass-produced with front-wheel drive and four-wheel independent suspension, as well as unibody construction, omitting a separate chassis, and instead using the body of the car itself as its main load-bearing structure.
In 1954, Citroën produced the world's first hydropneumatic self-levelling suspension system; then the revolutionary DS, the first mass-produced car with modern disc brakes, in 1955. In 1967, swiveling headlights that allowed for greater visibility on winding roads were introduced in several models. These cars have received various national and international awards, including three European Car of the Year awards.
