R-003 / CFD 65 mph

Z is direction of travel, X is side force, Y is parallel to gravity. Directional indicator in lower left corner of video references the wind tunnel and not the object- ignore it.

Simulation results from a run of a Gen. 1 Tesla Model 3 with a trunk-mounted platform wing at 65mph on a rolling road.
