In 2012, Citroën announced plans to enter the World Touring Car Championship. The team transformed a DS3 WRC into a laboratory vehicle to help with early development, while the engine was an evolution of their WRC engine which had been used in the WRC since 2011. Citroën started developing the car for the new TC1 regulations, which were brought forward a year early in 2014 to expedite the entry of Citroën into the championship. The introduction of the new regulations a year earlier than planned gave a seven-month development headstart to Citroën over the other manufacturers. This large development advantage combined with a big budget and a strong driver line-up made Citroën the clear favourite going into the first season of the new regulations in 2014. Citroën would go on to win most of the races that season as well as the manufacturers' title, while José María López won the drivers' title. The team would repeat this feat in 2015 and 2016, before the factory team left the series at the end of 2016. A number of Citroëns were still raced by other teams in 2017, but were outpaced by the Hondas and the Volvos.
