The Citroën DS4 Racing, unveiled at today's Geneva motor show extends the marque's hot Racing brand to the the DS4. The 256bhp engine is Citroën's most powerful road engine to date.
Officially the DS4 Racing is a concept, but the model is strongly-tipped to go into production, possibly early next year, to take on the Ford Focus ST and Renaultsport Megane.
The heavily-boosted 1.6-litre turbo engine has been tuned by Citroën Racing and its 256bhp output is around 50bhp more than the Mini Countryman JCW and 60bhp more than the DS3 Racing, which both use the same PSA/BMW co-developed 1.6-litre four.
Despite the storming specific power output of 160bhp per litre, Citroën claims an impressive 155g/km of CO2. As yet, performance and economy figures are undisclosed, but if the production car shares the same output, a sub-six second 0-60 and 155mph limited top speed ought to be achievable.
In line with the Racing theme, the chassis is lowered 35mm and the front and rear tracks extensively widened — 55mm at the front and 75mm at the rear. Also bigger are the 19in wheels shod with 235/40 rubber.
