Citroën returned to the sport with a fully factory-supported team after competing part-time in 2016 to focus on the development of their 2017-generation car. The DS3 WRC was succeeded by the C3 WRC, a brand-new car based on the Citroën C3. The decision to re-enter the World Rally Championship coincided with Citroën withdrawing its factory support for the Citroën C-Elysée WTCC and its World Touring Car Championship programme. The team signed Kris Meeke and co-driver Paul Nagle to contest the full season, while Craig Breen and Scott Martin will share a car with Stéphane Lefebvre between events—as they did in 2016—until a third C3 WRC becomes available; Citroën also entered a DS3 WRC for Breen and Lefebvre. Gabin Moreau returned as Lefebvre’s co-driver following an injury at the 34. Rallye Deutschland that saw him sit out the final events of the 2016 season. Khalid Al Qassimi is scheduled contest selected events in a fourth C3 WRC.
