The car’s length has grown by 55mm compared with Citroen’s last WRC competitor, the 2015 Citroën DS3 WRC, making it 4150mm long. The increased length is thanks to less restrictive aero limits leading to a more prominent front bumper and larger front spoiler.
To match the additional front downforce, a bigger fixed rear wing has been added to the rear and placed as far back as possible for maximum effect.
Citroën says despite the car’s concept label, its exterior has been designed with the new 2017 WRC regulations in mind, meaning it could be used in next year’s season without modification. However, such is the pace of development in motorsport, it’s likely that small changes will be made during the closing months of 2016.
Under the bonnet is a turbocharged 1.6-litre four-cylinder engine that produces 380bhp, making the competition car almost four times as powerful as Citroën’s current most potent C3 road model and 80bhp more potent than the 2015 car. The 2017 car’s power increase comes largely thanks to a bigger 36mm restrictor, as per the championship’s new engine regulations.
Despite its larger size, the new regulations mean the C3 WRC weighs 25kg less than Citroën’s 2015 challenger, which weighed 1200kg as per 2015 regulations.
The C3 WRC concept will influence the competition model that’s set to make its WRC debut at the Monte Carlo Rally in January 2017. It’ll go up against other factory-supported cars from Volkswagen, Hyundai, M-Sport and Toyota, which will also be fielding its first official WRC entry since it departed as champion in 1999.
Citroën returns to the WRC as the second most successful manufacturer after Lancia, with 94 wins and eight constructors titles under its belt. Most of the brand’s success came during a lengthy period of dominance that started in 2004 with star driver Sébastien Loeb.
Britain's Kris Meeke is helping with development of the C3 WRC and will be the team's lead driver for the 2017 season alongside co-driver Paul Nagle.
