Aspects of the present invention relate to an active diffuser mechanism for a vehicle comprising a mounting mechanism for connecting a diffuser body to a body of a vehicle such that the diffuser body is moveable between a stowed position and a deployed position in which an airflow surface of the diffuser body is spaced further away from the body of the vehicle than in the stowed position. The mounting mechanism comprises a linkage mechanism configured such that the diffuser body follows a linear translation path and a rotational path during movement from the stowed position to the deployed position. Aspects of the present invention also related to an active diffuser assembly, an active diffuser system and a vehicle comprising such an active diffuser mechanism.

Active diffuser mechanism

An aerodynamic apparatus () for a vehicle (), the aerodynamic apparatus comprising: a bonnet () having a leading edge () and a trailing edge (); a bonnet spoiler () having a leading edge () and a trailing edge (), and being positionable vertically above the bonnet () and separated therefrom to form an airflow duct () therebetween; and a grille () comprising a trailing edge () and a front face separated by a curved upper portion (), wherein the trailing edge () of the grille () is positionable adjacent to the leading edge () of the bonnet ().

Aerodynamic apparatus

Embodiments of the present invention provide airflow apparatus for a vehicle comprising: an airflow duct extending rearwardly from a front region of said vehicle, the airflow duct having an airflow inlet and an airflow outlet; a cooling duct, separate from the airflow duct, the cooling duct having a cooling inlet and a cooling outlet, wherein the airflow outlet is in proximity to the cooling outlet such that, in use, airflow through said airflow outlet influences airflow through said cooling outlet, the cooling outlet and/or the airflow outlet is in a bonnet of the vehicle and, in use, airflow exits the airflow outlet substantially parallel said bonnet.

Modifying aerodynamic performance of a vehicle

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.

Vehicle aerodynamic apparatus

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.

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.

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.

The present application relates to a vehicle (). A first duct () having a first duct inlet () and a first duct outlet () is provided on a first lateral side of the vehicle (). A second duct () having a second duct inlet () and a second duct outlet () is provided on a second lateral side of the vehicle (). The first and second duct inlets () are arranged substantially in line with or inset from the respective first and second lateral sides of the vehicle (). The first and second duct outlets () are disposed at or proximal to a rear of the vehicle () 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 (). Duct sidewalls are formed by surfaces of rear pillars of the vehicle ().
