A front vehicle-body structure flows air from the vehicle lower side to its upper side. After hitting a front bumper face, the air is separated and flows around and along a top face of an exterior member, ensuring aerodynamic performance. Embodiments include exterior members covering the upper side of an engine room, and a front grille disposed on a lower side relative to a front end portion of the exterior member. A rectification member extends the width of the exterior member in the vehicle width direction on the lower side of the exterior member front end portion. The rectification member includes a front piece portion extending toward the vehicle up-down-direction lower side from the exterior member to an upper end portion of the front grille, and a lower piece portion extending toward the vehicle rear side from an upper end of the front piece portion.

A rear-end air guide device for a motor vehicle includes a rear spoiler having a spoiler surface and a rear wing arranged in a vehicle vertical direction above the rear spoiler. The spoiler surface faces toward the rear wing, and the spoiler surface facing toward the rear wing is adjustable in a vehicle longitudinal direction.

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.

A rear spoiler system includes a roof portion forming an upper frame of a vehicle body, a rear spoiler positioned at the rear of the vehicle body, connected to the roof portion and including an opening through which air passes, a variable shutter positioned at the rear spoiler to adjust the opening amount and opening position of the opening, and an actuator operating the variable shutter.

An active front deflector assembly having a deflector panel, actuator, and linkage assemblies each with a predetermined ratio of the links to each other for motion of the deflector panel. The assembly deploys and retracts based on vehicle requirements, and, when deployed, redirects the air flow in the front of the vehicle to improve the vehicle aerodynamics for either fuel economy or performance characteristics. Additionally, it allows for the deflector panel to retract so the vehicle meets ground clearances, etc. The deflector panel is also both rigid and semi-rigid to absorb impact energy. The drive shaft transmits the drive from the actuator coupled to one linkage assembly to the other linkage assembly for moving the deflector panel between the deployed/retracted positions. The actuator is clutched to prevent damage to the system.

An aerodynamics control system for a vehicle may include a repositionable aerodynamic device disposed at a portion of the vehicle, a controller operably coupled to components or sensors of the vehicle to receive information including vehicle performance data and position information for the aerodynamic device, and a vehicle location sensor determining location information for the vehicle. The controller stores the vehicle performance data and the position information in association with the location information for each of a plurality of locations. Responsive to detecting an approach of the vehicle to one of the locations, the controller provides a control instruction to position the aerodynamic device based on recorded vehicle performance data and recorded position information associated with the one of the locations.

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 drag reducing device includes an air flow turning component having a curved surface adapted to turn air flow passing over the curved surface, a first mounting component for connecting the air flow turning component to a rear door of the vehicle, and a second mounting component for connecting the air flow turning component to one of the opposite side walls of the vehicle. The mounting components are configured so that the air flow component is automatically in a deployed position when the rear door is closed, so the air flow turning component turns air flow passing along the side the vehicle inward to thereby reduce drag. The mounting components are further configured so that the air flow component is automatically stowed between the rear door and the vehicle side wall when the door is fully opened. The air turning component is sized for a minimal prominence when stowed.
