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).

Abstract: A baffle assembly for directing air to a charge air cooler disposed within an engine compartment and mounted above a radiator module and behind a hood latch support bracket extending between an upper and lower structure of the vehicle frame. The baffle assembly includes a lower baffle for directing air upwardly towards the charge air cooler and an upper baffle for directing air downwardly towards the charge air cooler. An air diverter extends from either the lower or upper baffle for positioning behind the hood latch support bracket to reduce turbulence behind the hood latch support bracket and more uniformly distribute airflow to the charge air cooler. In other words, the air diverter reduces the recirculation region and turbulence by diverting the airflow behind the hood latch support bracket smoothly with minimum air flow losses and improves the mass flow rate through the charge air cooler, therefore significantly improving efficiency.
