Citroën tests next year’s WRC car on asphalt

27 July 2016

Three months after its first outing, Citroën Racing’s 2017 World Rally Car made its asphalt debut on the bumpy roads of Aude in southern France.

By opting to hold the first development sessions on asphalt, the Citroën Racing engineers had given priority to a surface used in the majority of World Rally Championship events. “By test-driving the car in the toughest conditions first, we were able to check the reliability of all the components,” explained Citroën Racing technical director Laurent Fregosi. “What is more, there isn’t just one type of gravel. Finland and Mexico offer completely different surfaces. So we wanted to explore that diversity by testing the car on asphalt, where the operating window is narrower.”

In terms of the regulations, the differences between a WRC car’s gravel and asphalt setups are minimal, but they are vital. “The biggest change is in the suspension,” Fregosi continued. “We use lighter parts that allow us to reduce the ground clearance. The drivetrain kinematics are also adapted to the 18″ wheels. Large wheels mean we can increase brake disc diameter and use water-cooled callipers.

“We should also mention the lighter body protection. On the aerodynamic front, we now have the ability to adapt the lower part of the front bumper specifically for asphalt. During this first session, we worked in particular on the programming of the centre differential. The aim is to distribute power between the front and rear axles according to the situation. Obviously, the settings will be different from one surface to another. The drivers were also able to assess the effects of mechanical parameters, such as spring stiffness, the anti-roll bar and the differential. Overall, the results were positive and we know where we are at. Once again, the car’s reliability allowed us to get plenty of kilometres in.”
