Abstract: A multi-airfoil element wing includes a central single-airfoil element and an outer dual-airfoil element positioned outboard of each side of the central single-airfoil element. The single-piece member defines aerodynamic surfaces of the central airfoil element and both of the outer dual-airfoil elements. The single-piece member includes a carbon fiber resin hollow body forming at least a portion of the central single-airfoil element and of both outer dual-airfoil elements.

Abstract: Multiple vertical panel strakes extend from a rear underbody of the automobile in a street configuration. Multiple vertical panel extensions include extension coupling elements designed to removably couple the vertical panel extensions to the plurality of vertical strakes in a track configuration. When the rear underbody aerodynamic diffuser is in the street configuration, the plurality of vertical panel extensions are uncoupled from the plurality of vertical panel strakes and the vertical panel strakes have an overall width that extends a vertical street distance. When the rear underbody aerodynamic diffuser is in the track configuration, the plurality of vertical panel extensions are removably coupled to the plurality of vertical panel strakes and the combined vertical panel strakes and vertical panel extensions have an overall width that extends a vertical track distance that is greater than the vertical street distance.
