Citroën formally announced its intentions to withdraw from full-time competition at the end of the 2015 season in order to focus on the development of the C3 WRC.[8] The team contested selected events during the 2016 season, using the DS3 WRC as a testing platform for selected parts.[6] Further testing and development was carried out using the Citroën C-Elysée WTCC, the car used by Citroën in the World Touring Car Championship.[6] The C3 WRC's début in 2017 coincided with the widespread revisions to the sport's technical regulations.[9]
