Citroen is a French automobile manufacturer, part of the PSA Peugeot Citroen group since 1976, founded in 1919 by French industrialist Andre-Gustave Citroen. In 1934, the firm established its reputation for innovative technology with the Traction Avant. This car was the world's first mass produced front wheel drive car, but also one of the first to feature a unitary type body, with no chassis holding the mechanical components. In 1954 they had produced the world's first hydro-pneumatic self-levelling suspension system then, in 1955, the revolutionary DS, the first mass production car with modern disc brakes and, in 1967, they introduced in several of their models swiveling headlights that allowed for greater visibility on winding roads. These automobiles have received various international and national level awards, including three European Car of the Year. With a successful history in motorsport, it is the only automobile manufacturer to have won three different official championships from the International Automobile Federation: the World Rally Raid Championship five times, the World Rally Championship eight times and the World Touring Car Championship. Citroen has been selling vehicles in China since 1984 largely via the Dongfeng Peugeot-Citroen joint venture, which today represents a major market for the brand. In 2014, when PSA Peugeot Citroen ran into severe financial difficulties, the Dongfeng Motor Corporation took an ownership stake.
