Geneva motor show 2012: Citroën's DS4 Racing concept French car-maker Citroën will present a high performance "Racing" version of its DS4 crossover at March's Geneva motor show. Despite its name, this hot hatch is in fact a road car, albeit one that has benefited from the knowledge of Citroën's Racing engineers, who have tweaked the 1.6-litre turbocharged petrol engine to produce 256bhp - a record for a Citroën production car. The engineers have also lowered the ride height by 35mm and widened the car's track (by 55mm at the front and 75mm at the rear), as well as fitting 19in wheels, four-piston brake callipers and 380mm brake discs at the front. Visually, the DS4 Racing can be identified by its "textured-effect" matt grey paint, which is said to catch the light in a way that enhances the lines of the car, plus there's a number of carbon-fibre additions, such as wheel arch extensions, a front splitter and a diffuser. Rather than releasing any projected performance figures, Citroën claims only that if it were to make it into production, the DS4 Racing would emit 155g/km of CO2. The Citroën DS4 Racing will appear at the Geneva motor show, which opens its doors to the press on March 6.
