Citroen C4 WRC: Citroen Sport's New Weapon
The Citroen C4 WRC - Citroen Sport's new weapon - made its debut in the Monte Carlo rally in 2007. It is the car to replace the Xsara WRC, winner of three world manufacturers crowns between 2003 and 2005. In the expert hands of Citroen Sport's engineers at Versailles Satory, the C4 Citroen Sport concept car became the C4 WRC.
Although the overall styling was maintained, the car had to be adapted to international regulations and performance requirements. This is where the design office of Citroen Sport stepped in. The project working group came up with a first rolling model of the Citroen C4 WRC that was already a long way from the original concept. The roof, for example, was no longer made of glass, since this is banned in rally racing. The front and rear wings, bumpers and spoiler were modified to satisfy regulations and performance criteria. To save time and money, a number of body parts were studied in wind tunnels on a scale of 1 before validation of the full-size parts at the end of the project.
