An active rear airfoil arrangement (10) for a trailing area of a vehicle having a turbulence creating area. The arrangement (10) is for connection with a static rear horizontal spoiler (20) associated with the rear portion of a vehicle and includes an active rear horizontal spoiler (30a, 30b, 30c). The active rear horizontal spoiler (30a, 30b, 30c) moves to a deployed position and forms a flow passage (48a, 48b, 48c, 48d) that extends horizontally across the top of a liftgate (12). In another aspect of the invention the active rear airfoil arrangement (10) includes vertical left and right active spoilers (32a,32b; 36a,36b) that move to create a flow passage (74,76,88,90) on the left side and right side of a liftgate (12).

A side step for a vehicle includes an inner side coupled to or adjacent to a vehicle body, an outer side, a top side, a bottom side, a front end and a rear end, where the front end is adapted to be arranged closer to a front of a vehicle than the rear end. An air guide is provided at one or both of the front end and the rear end, the air guide projects outwardly relative to a central portion of the side step that is spaced from the air guide, and the air guide projects outwardly from one or both of the top side and bottom side, and the air guide is thicker, in a vertical direction, at said one or both of the front end and rear end than is the air guide at a location between the front end and rear end.

Tire cooling systems operatively disposed along a vehicle body adjacent a vehicle tire include a deflector panel displaceable between retracted and deployed positions. In the retracted position, a first nominal volume of air flows along the vehicle tire during operation. In the deployed position, a second nominal volume of air that is greater than the first nominal volume of air is directed along the vehicle tire. An actuator is selectively operable to displace the deflector panel between the retracted and deployed positions. A sensor registers data having a relation to a physical characteristic or health condition of the vehicle tire. A controller executes instructions to determine using the data whether or not the physical characteristic of the vehicle tire exceeds a predetermined threshold as well as control displacement of the deflector panel. Vehicles including tire cooling systems and method of operation are also included.

An air conduction device for a motor vehicle including an air conduction element and a movement device with adjustment kinematics. The air conduction element is movable relative to the remaining body as at least part of a tail side part of the vehicle body. The air conduction element moves between an inoperative position and at least one final operating position. The tail side part has a flow guiding area along which air flows which is designed to face an area surrounding the motor vehicle. The air conduction element has a surface which is at least part of the flow guiding area. The air conduction element is configured in its final operating position to lengthen the flow guiding area in the direction of a longitudinal body axis (X) of the body. The adjustment kinematics are configured in the form of multipoint joint kinematics.

Various embodiments are directed to an air jet shield. The air jet shield may include a support frame configured to attach to a vehicle utilizing a set of security straps. Sets of V-shaped and concave air ducts may be horizontally and vertically coupled to the support frame, respectively. Each of the air ducts may have a decreasing cross-sectional area and include (i) an inlet that receives air from a surrounding environment during a travel of the vehicle into a headwind or crosswind and (ii) an outlet that dispenses the air received from the inlet as a free air jet. Upon entering a headwind or crosswind, the free air jet creates a wind shear causing rotation at an increased velocity. Within the free air jet and surrounding the vehicle, static air pressure and wind velocity is decreased, thereby causing a reduction in aerodynamic drag during travel.

A motor vehicle side spoiler arrangement with a spoiler blade which can be moved in a motorized manner between a retracted rest position and a laterally extended spoiler position. A spoiler shell is fixed on the vehicle and provided with a shell rear wall, a guide mechanism which guides the spoiler blade in the longitudinal direction, and an actuating motor. A sliding seal lip is provided between the spoiler blade and the shell rear wall, which sliding seal lip closes a front-side gap (S) between the spoiler blade and the shell rear wall in the spoiler position of the spoiler blade.

The invention relates to a vehicle window for a vehicle and to a method for producing said vehicle window, comprising a glass body, which has an inside and an outside, which are spaced apart by a wall thickness of the glass body, comprising an externally peripheral edge that delimits the glass body, wherein the glass body comprises a planar extent that extends in a two-dimensional plane or a spherically curved plane, wherein the glass body has a three-dimensionally shaped functional region having a free form that bulges with respect to the plane of the glass body, and the glass body having the three-dimensionally shaped functional region is produced from a pressed glass.

An air guide device for a motor vehicle having an air guide element and a movement mechanism. The air guide element forming a rear side part of a body of the motor vehicle so as to be movable relative to the remaining body. The air guide element is movable between an inoperative position and at least one operating end position. The air guide element, in its inoperative position, is flush with the remaining body. The rear side part has a flow guide surface which faces an environment of the motor vehicle and along which air flows. The air guide element has a surface which is at least part of the flow guide surface. The air guide element, in its operating end position, is configured to extend the flow guide surface along a body longitudinal axis (X) of the body.

The invention concerns a trim panel arrangement for trimming a body element of a vehicle, with a pivotably mounted air guide device which is movable by means of a kinematic arrangement into a retracted first function position and a fully extended second function position and vice versa. At low speeds and also at high speeds, this should ensure an optimum aerodynamics of the motor vehicle in the air flow. This is achieved in that the air guide device is formed in two parts and comprises a first and a second trim part which are pivotably connected together, and that the kinematic arrangement is formed from a primary and a secondary lever drive. The invention furthermore concerns a method for forced movement of the air guide device.

A vehicle body side structure is provided. A vehicle body side structure includes a front fender, a side sill garnish, and an aerodynamic duct. The front fender has a fender recess portion below a first wheel arch portion. The side sill garnish has a second wheel arch portion that faces the fender recess portion at the outer side in the vehicle width direction at interval and faces a rear end of the first wheel arch portion. The aerodynamic duct is interposed between the second wheel arch portion and the fender recess portion. The width of the second wheel arch portion gradually decreases in the front-rear direction of the vehicle body as it extends upward from the front end portion of the side sill garnish to an upper edge.
