Citroën is continuing to evolve the DS line with the unveiling of a new concept at the Geneva Motor Show - Citroën DS4 Racing.

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 256bhp (160bhp per litre). This performance is accompanied by CO2 emissions of 155g/km.

The chassis has been lowered by 35mm and the track widened by 55mm at the front and 75mm at the rear. The concept is also fitted with larger diameter 19-inch wheels and 235/40 tyres.
