The DS 4 is a compact car and it is the second model in the new premium (luxury vehicle) DS sub-brand created by Citroën to run alongside its mainstream cars. It was officially launched in 2011 internationally, but already on sale in some countries in late 2010. Based upon the Citroën C4 II, it features raised suspension to resemble a compact SUV and repositioned door handles to give a coupe-like silhouette. The rear windows are fixed, and do not slide or open outwards
