Abstract: A vehicle having a first lateral diffuser provided on a first side of the vehicle and a second lateral diffuser provided on a second side of the vehicle. The first and second lateral diffusers are movably mounted and can be displaced from a retracted position to at least a first deployed position.

Abstract: A vehicle having one or more guide vanes for guiding airflow along a side of the vehicle. The guide vane(s) can be moved from a retracted position to a deployed position. The vehicle can include sills which can be displaced laterally outwardly and downwardly a retracted position to a deployed position.

Abstract: A vehicle having a transverse panel and a transverse aerodynamic member, and a control unit. The transverse aerodynamic member is movable to an operating position in which it is spaced apart from the transverse panel. In that operating position, the transverse aerodynamic member is operable to direct airflow downwardly at the rear of the vehicle to control the vertical propagation of the wake formed behind the vehicle.

Abstract: A vehicle having one or more guide vanes each disposed at each of a respective front and/or rear quarter of the vehicle for guiding the airflow in the vicinity of an adjacent wheel of the vehicle.

Abstract: The present application relates to a vehicle (401). A first duct (457) having a first duct inlet (467) and a first duct outlet (469) is provided on a first lateral side of the vehicle (401). A second duct (457) having a second duct inlet (467) and a second duct outlet (469) is provided on a second lateral side of the vehicle (401). The first and second duct inlets (467) are arranged substantially in line with or inset from the respective first and second lateral sides of the vehicle (401). The first and second duct outlets (469) are disposed at or proximal to a rear of the vehicle (401) and arranged, in use, to direct respective first and second jets of air inwardly to control the lateral propagation of a wake formed behind the vehicle (401). Duct sidewalls are formed by surfaces of rear pillars of the vehicle (401).

Abstract: A vehicle (1; 101) is provided comprising a deployable closure panel (3; 103) which, in a deployed position, closes an air inlet (5; 105) of a vehicle body so that one edge thereof aligns with one edge of the vehicle body. A method is also provided for moving the closure panel (3; 103) into one of the deployed position and a retracted position, based on the vehicle (1; 101) satisfying a criterion. A control system (50) is provided for controlling deployment of the deployable closure panel. The control system (50) is configured progressively to deploy the deployable closure panel from the retracted position to the deployed position in dependence on an operating parameter associated with the vehicle (1; 101) to increase airflow through a closed channel formed by an airflow modification device disposed transversely across a recessed channel formed in a bonnet extending towards a bonnet rear edge.

Abstract: A bonnet for a vehicle and a control unit. The bonnet includes a front edge and a rear edge. A recessed longitudinal channel is formed in the bonnet and extends from the front edge towards the rear edge. An airflow modification device is disposed transversely across the longitudinal channel for controlling airflow over the bonnet, wherein the airflow modification device and the recessed channel form a conduit, the conduit having a cross-sectional area which is diverging as the conduit extends towards the rear edge and/or a movable element may be provided to change the cross-sectional area.
