The crews competing in the Citroen Total World Rally Team's two C3 WRCs will tackle the only rally of the championship held exclusively on snow and ice.
Dominated by Scandinavian drivers in its first 28 years in the WRC, Rally Sweden has only been won three times by non-Nordic crews since 1973. Winners for the first time in 2013, Sebastien Ogier and Julien Ingrassia are the only ones to have achieved the feat three times - their other victories coming in 2015 and 2016.
They certainly know how to manage the subtleties of this high-speed balancing act, which differs enormously each year due to the amount of snow and ice on the roads.
After securing Citroen Racing's historic 100th win in the WRC at Monte-Carlo and the 45th of their career, Sebastien and Julien will have the tough job of running first on the road with their C3 WRC in Sweden. This means they will be carving out the racing line for the rest of the field if there is fresh snow on the surface, another difficulty at an event that is hardly lacking in challenges.
