A vehicle has external bodywork including an upper surface and an under surface, the under surface having at least one aperture, and the vehicle comprising lower ducting located within the external bodywork and communicating with that aperture, the upper surface having at least one aperture, and the vehicle comprising upper ducting located within the external bodywork and communicating with that aperture, the upper ducting and the lower ducting leading to a fan adapted to selectively draw air through the respective ductings, the vehicle further comprising a control unit adapted to receive information as to the vehicle dynamic state and, in the light of that state, draw air through the lower ducting or through the upper ducting. Thus, a choice can be made between enhanced levels of downforce on the one hand, and low drag on the other. By providing pre-set thresholds for parameters such as speed, g-force, vehicle attitude or the like within the control unit, the car can be tailored so that it is optimised for low drag during high speed straight-line driving, when tight cornering is unlikely, and optimised for greater downforce when lateral grip is more likely to be needed.

A motor vehicle body with an air-guiding device and with a trailer coupling mounting device. The air-guiding device is formed in a rear-end region of the motor vehicle body. The trailer coupling mounting device is adjustable into a rest position and into an active position. The trailer coupling mounting device, in at least the rest position, is at least partially covered with respect to surroundings by the air-guiding device, which is settable into a first operating position and a second operating position. For positioning the trailer coupling mounting device into its active position, the air-guiding device is settable into its second operating position and, after or together with the positioning of the air-guiding device into its second operating position, the trailer coupling mounting device is configured to be movable along a body vertical axis (Z) of the motor vehicle body.

For positioning of the trailer coupling mounting device into its active position, the trailer coupling mounting device is movable along a body longitudinal axis of the motor vehicle body, and, before or together with the positioning of the trailer coupling mounting device into its active position, the air-guiding device is settable into an intermediate position which has a pivot angle greater than a pivot angle of the second operating position.

A rear arrangement for a vehicle includes a trailer coupling mount and a rear diffuser having an adjustable air-guiding element which is adjustable between a retracted position and an extended position. The trailer coupling mount is pivotable about a pivot axis, which is congruent or parallel to the vehicle transverse axis (y), between an inoperative position and a use position. The air-guiding element in the retracted position at least partially conceals the trailer coupling mount, and the air-guiding element has to be brought into the extended position so that the trailer coupling mount can be pivoted into the use position.

A vehicle, a vehicle brake cooling system, a computer program product, and a method of controlling a vehicle in a manner to achieve enhanced aerodynamic performance of the vehicle and active cooling to the wheel brakes during operation of the vehicle. The vehicle includes one or more a vehicle air vents moveable between a first position and a second position, and one or more processors of a computing system. The one or more processors are configured to dynamically conduct, in response to a detection as sensor data one or more of a current position of the vehicle air vents, a current temperature of vehicle wheel brakes, and a current speed of the vehicle, a vehicle brake analysis of the sensor data. The one or more processors are also configured to dynamically control, in response to the vehicle brake analysis and wireless network data, the vehicle air vents between the first position to enhance the aerodynamic performance of the vehicle and the second position to selectively direct ambient airflow to the vehicle wheel brakes in a manner that selectively cools the vehicle wheel brakes.

A body part for a motor vehicle with a positioning structure is provided. The body part includes an outer panel and an inner panel, and a backside of the outer panel is provided with a positioning structure to position the outer panel relative to the inner panel for their assembly, the positioning structure including a clamping seat configured to receive a shaft of a rack for positioning the outer panel thereon during manufacturing of the outer panel, and to be engaged in an opening of the inner panel to position the outer panel relative to the inner panel. The positioning structure combines the arrangements of both positioning holes and positioning ribs, thereby greatly enhancing the eligibility rate of spray painting and welding stability.

An active liftgate spoiler used on a liftgate of a vehicle. The liftgate has an upper surface and is typically a rear liftgate or hatch on the rear side of the vehicle. A housing is connected to the upper surface of the liftgate. There is a moveable panel connected to the housing using a connection. The connection is formed by a four bar linkage that forms a portion of the connection between the moveable panel and the housing. An actuator, which in one embodiment is a single rotary actuator is connected to the four bar linkage and causes the movement of the moveable panel.
