Citroën DS Wild Rubis concept

The Citroën DS Wild Rubis concept is the French manufacturer's foray into the premium SUV market, to be shown at the Shanghai auto show next Saturday. At 4,700mm long it's slightly larger than a BMW X3 or Audi Q5, with a particularly generous wheelbase of 2,900mm, presumably to offer the rear passengers a little more space - major consideration in China. It was designed in the DS studio in France, something the company is keen to promote given China's desire for chic European luxury goods.
