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, 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 they produced the world's first hydropneumatic self-levelling suspension system then, in 1955, the revolutionary DS, the first mass-produced 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 cars have received various national and international awards, including three European Car of the Year.
Citroën has been selling vehicles in China since 1984, largely via the Dongfeng Peugeot-Citroën joint venture, which today represents a major market for the brand. In 2014, when PSA Peugeot Citroën ran into severe financial difficulties, the Dongfeng Motor Corporation took an ownership stake.
