An apparatus for reducing the aerodynamic drag of a bluff body vehicle. The apparatus including a blower or other method of providing a gas flow, and a plenum enclosure (200) having an inlet port (203) connected to receive gas from the blower (201), and an outlet (202) wall with a wide area plenum outlet (205) for producing a wide area gas outflow profile. In a preferred embodiment, the plenum enclosure is positioned against a rear-facing base of the bluff body vehicle so that the outlet wall is on an opposite side from the base, and gas outflow from the wide area plenum outlet is in a rearward direction out to a low pressure recirculation region adjacent the outlet wall.
