Abstract
An air diffuser assembly for attachment to a twist beam on a rear suspension system of an automobile that reduces the coefficient of drag (Cd) as the automobile is being driven. The air diffuser assembly includes an wind deflection portion that includes a top longitudinal edge and a bottom longitudinal edge being spaced apart by a pair of lateral edges. The main body further includes a first slope extending outwardly and downwardly from the top longitudinal edge and a second slope extending outwardly and upwardly from the bottom longitudinal edge. The first slope and second slope meet at an edge for deflecting an airflow across both the first slope and the second slope. The wind deflection portion includes an air tunnel diffuser defining an air passage for guiding airflow therethrough and directing it behind the automobile away an undercarriage of the automobile to further reduce the coefficient of drag (Cd).
