1. A drag reducing apparatus for a vehicle rear end having adjacent rear doors, each said door including opposed pairs of parallel walls and a substantially flat upwardly extending rear surface intersecting said walls to provide opposed pairs of parallel edges therewith, said drag reducing apparatus comprising:

  • a pair of inflatable lobes, each said lobe including opposing top and bottom surfaces, opposing side surfaces, a mounting surface proximal to the rear door, and a substantially planar aft-face distal to the rear door;

    each said lobe having a deflated position and a deployed position relative to the rear end of the vehicle;

    each said lobe in said deployed position overlying said surface therefrom between said opposed pairs of parallel edges; and

    ,each said lobe in said deployed position provides an aerodynamic substantially planar contour extending rearwardly of the rear end of the vehicle wherein each of said opposing side surfaces having at least a first slope relative to each of one opposed pair of parallel edges, and each of said opposing top and bottom surfaces having at least a second slope relative to each of another opposed pair of parallel edges.
