A vehicle drag reduction structure for use at the rear of a vehicle has at least one concave surface. Typically the structure has an outer flow surface 5, 8 and an inner flow surface 14, which may meet at a downwind edge to form a structure tapering in the downwind direction. The surfaces may each comprise a curved portion 7 and a flat portion 6. The structure may comprise two or three outer flow surfaces 5, 8, for example extending from side and top edges of a vehicle, and a central flow divider 13, which may taper in the downwind direction, extend rearward from a rear area of a vehicle, taper linearly or non-linearly, taper from a square, circular or polygonal base, and have at least one curved surface. The structure may comprise a fairing located proximate and parallel to an outer flow surface. The structure may be integrally formed with a door 4. A vehicle with such a structure is also provided, which may be a trailer.
