Citroen has a reputation for innovation and revolutionary engineering, as reflected in their slogan “Créative Technologie”. This history of innovation started just after its founding when André Citroen introduced the first mass production of vehicles outside the United States – a technique developed while producing armaments for the French military in World War I. In 1924, Citroen produced Europe’s first all-steel bodied car, 10 years later they introduced the first mass produced front wheel drive car and the first car to feature a monocoque body. Another 20 years later, Citroen produced the first hydropneumatic self-levelling suspension, then in 1955 the DS was the first European car with disc brakes. Citroen was also one of the early pioneers of aerodynamic designs for cars. They also experimented in producing a Rotary engine, but this ultimately caused losses. Citroen has produced numerous well known cars throughout its history, such as the 2CV, the DS. Presently, Citroen produce mainly hatchbacks, of different sizes ranging from the DS3 to the C4. Citroen have enjoyed much success within WRC, winning 8 manufacturer titles.
