This invention provides a foldable/retractable and unfoldable/deployable, rearwardly tapered assembly for vehicle bodies that accommodate dual swing-out doors. The aerodynamic assembly includes a right half and a left half mounted on respective doors. Each half is constructed with a series of panels that form half of a tapered box when deployed on the rear of the vehicle, the bottom panels and top panels being sealed together at a pair of weather seals along the centerline. The panels are joined by hinges and the top and bottom panels form two sections along diagonal lines to facilitate folding of all panels in a low-profile stacked orientation. A swing arm assembly and gas spring biases the panels into a deployed position that can be refolded. The top and bottom panels are partly inwardly folded when deployed to define external valleys using a stop assembly that prevents the panels from “locking up”.
