As with DS3 Racing, Citroën Racing's engineers have taken their WRC expertise and put their unique stamp on Citroën DS4 to create this hot blooded new concept. The DS4 Racing concept features new carbon fibre components including an air diffuser, front splitter and wheel arch extensions. The 1.6-litre turbo petrol engine, developed by Citroën Racing, provides up to 256 bhp (160 bhp per litre), which is a record for a Citroën series production car. This performance is accompanied by CO2 emissions of 155 g/km.
Citroën Racing's engineers have modified the chassis and running gear with the utmost precision. The chassis has been lowered by 35 mm and the track widened by 55 mm at the front and 75 mm at the rear. The braking system boasts fixed four-piston callipers at the front together with special 380 mm diameter discs. The concept is also fitted with larger diameter 19-inch wheels and 235/40 tyres.
Another stand out feature of the DS4 Racing concept is the textured-effect matt grey paint, which catches the light to further enhance the lines of the car. Further exterior refinements include a two-tone roof and two-tone wheels with a special DS4 Racing design.
