Fine-tuned during extensive wind tunnel testing, Citroën DS3 WRC’s bodywork accentuates the curves of the original model. The wings and the bumpers have been redesigned in order to attain the maximum authorised width of 1,820mm and to accommodate the 18-inch wheels (tarmac version).
The front bumper now includes an aerodynamic splitter, whilst a stylish rear spoiler has been attached to the tailgate. The doors have also been altered, with the installation of polycarbonate fixed frame windows and the injection of foam designed to absorb energy in the event of a side impact.
Built using the production body shell, the DS3 WRC chassis includes a roll cage made of over 40 metres of steel tubing. The lower part has undergone several significant structural modifications:
— Upper attachment points added for the rear McPherson-strut suspension
— Optimisation of the lower suspension attachment points
— Integration of the transmission tunnel and the rear differential
— Lateral reinforcements added level with the body sills
Since DS3 is more compact than C4 WRC, Citroën Racing’s engineers worked on improving the position of each component so as to achieve the best possible balance between the car’s centres of inertia and centres of gravity.
