The Citroen brands was established in 1919 by industrialist Andre-Gustav Citroen, and throughout its history it has been known as one of the most pioneering car companies in the world. In 1934, it developed the Traction Avant, which was the world’s first mass-production front-wheel-drive car, but which helped send the company into bankruptcy, until Michelin took over. Hydro-pneumatic self-levelling suspension was another Citroen innovation in the 1950s, as were the world’s first mass-produced disc brakes. Swivelling headlamps featured on various Citroens in the 1960s. After going bankrupt again in December 1974, Citroen was partnered with Peugeot, and continued to produce unusual and innovative, if not huge-selling, cars.
