A vehicle front structure is provided for preventing a vortex from being generated between high-speed air separated from an outer edge of a deflector and low-speed air in a front wheel house due to a wind speed difference. Embodiments include a deflector disposed in front of a front wheel house projected downward from a lower surface of a bumper face. The deflector includes an air introducing section to introduce air into a space inside the deflector in a front portion of the deflector; and an intermediate-speed wind generating hole section that communicates with the air introducing section and generates an airflow at an intermediate wind speed, lower than a wind speed of air separated from deflector outer edges and higher than a wind speed of air in the front wheel house, in an area not opposing a tire in a vehicle front view of a portion immediately behind the deflector.

A drag reduction spoiler for a vehicle includes a fixed portion configured for attachment to the vehicle and an extendable top portion configured for movement relative to the fixed portion, the extendable top portion includes a first top portion and a second top portion. The drag reduction spoiler further includes first and second side spoiler portions configured for movement relative to the vehicle, and at least one actuator configured to deploy the extendable top portion, the at least one actuator being secured to the first top portion. The first top portion includes a first engagement element and the second top portion includes a second engagement element, the first engagement element being configured to engage the second engagement element when the first top portion is deployed by the at least one actuator such that the first top portion draws the second top portion outwardly as the first top portion is deployed.

A drag reducing device for a motor vehicle having a vehicle body and at least one substantially semi-circular wheel-well for receiving a wheel capable of vertical and rotational movements with regards to the vehicle body, the vehicle comprising unsprung masses associated with the at least one wheel; wherein the drag reducing device comprises a wheel-well cover configured to cover at least a portion of the wheel and of the wheel-well, a pivotal linkage pivotally connecting the wheel-well cover to the vehicle body, and a sliding linkage slidingly connecting the wheel-well cover to an element of the unsprung masses with one degree of freedom oriented in the vertical movement of the at least one wheel.

To improve the appearance of a tailgate provided with a rear spoiler, a tailgate of a vehicle includes a tailgate main body having a rear window opening a rear spoiler extending rearward from a part of the tailgate main body above the rear window opening a rear window panel that is mounted on an outer peripheral portion of the rear window opening of an outer surface of the tailgate main body and closes the rear window opening and a plate-shaped shield member mounted on a lower surface of the rear spoiler so as to shield a space formed between the lower surface of the rear spoiler and an upper end portion of the rear window panel.

A ventilation device for a vehicle includes a frame defining an opening and a closure device that includes at least one closure flap extending in the opening. The ventilation device includes a first section having a first external face and at least a second section having a second external face. The external face of the closure flap is formed by the first external face and by the second external face, the first section and the second section extending in continuity of one another. The first section is joined to the second section in a junction region, with a trimming piece that covers at least the junction region on the external face of the closure flap.

A hatch door, which comprises a rear spoiler and a side spoiler, which are fixedly connected to a base structure of the hatch door, wherein it is provided according to the invention that the rear spoiler is additionally disposed mechanically reversibly secured with respect to the side spoiler and vice versa by a mechanical connection.

The disclosed technology relates to a moveable panel, such as a fairing, of a vehicle, such as a semi-truck. For a number of reasons, it may be desirable to gain access to the area behind the fairing, for example, to access batteries, air/gas tanks, auxiliary power units, and/or other components that are mounted to the vehicle frame. In order to move the fairing with respect to the vehicle frame, one or more examples of a mounting system are provided that enables the fairing to pivot/swing away from the vehicle frame in a first direction (e.g., forward toward the front wheel). In some embodiments, the fairing may also pivot/swing away from the frame in a second direction (e.g., rearward toward the rear wheels) opposite the first direction. This multiple pivoting/swinging movement of the fairing enables access to different locations behind the fairing.

An active drag-reduction system has first 22 and second 24 fluid outlets located on a vehicle 10 adjacent to a low pressure (drag) region 12, wherein fluid ejected from the second fluid outlet 24 is at a higher pressure/ejection velocity than from the first fluid outlet 22. Turbulent and/or low pressure regions adjacent to vehicles are not uniform, but rather have a varying intensity. For instance, the centre of a region may have a lower pressure and/or more turbulent nature than the periphery of the region. The system injects relatively higher pressure air or relatively higher speed air into the relatively lower pressure/more turbulent part of the low pressure/turbulent region, and relatively lower pressure air or relatively lower speed air into the relatively higher pressure/less turbulent part of the low pressure/turbulent region, compared to each other.
