• a first configuration wherein the central portion makes with the rest of the rear wing a single seamless aerodynamic surface and wherein the rear edge of the rear tailgate defines the rear end of the vehicle's rear overhang;
• at least a second configuration wherein the central portion is in a rearward position along the roll axis relative to the rest of the rear wing and comprises a rear edge that projects posteriorly beyond the rear edge of the tailgate such that in the second configuration the rear end of the vehicle's rear overhang is defined by the rear edge of the centre portion of the movable wing.
