An active side vent system for a vehicle can include a housing disposed in a side vent opening defined by a recessed surface in a rear portion of a front fender of the vehicle, a set of louvers disposed in the housing and configured to pivot such that (i) in an open position, none of the set of louvers extends beyond an outer surface of the front fender and (ii) in a closed position, the set of louvers are substantially flush with the recessed surface of the front fender, and an actuator configured to control the pivoting of the set of louvers.

A lower aerodynamic screen of a front shield of a motor vehicle includes lateral air guides shaped to channel air passing under the aerodynamic screen towards front disc brakes of the vehicle, wherein each air guide is defined by two substantially vertical lateral walls and by an upper wall linked to upper edges of the lateral walls, the air guide being provided, downstream relative to a direction of flow of the air, with a window defined by rear edges of the lateral walls and the upper wall, from which the air emerges towards the disc brakes, the air guide further including a flap that is movable between a position in which it blocks the window and a position in which it is retracted from the window.

An aerodynamically effective attachment part or spoiler extension is disclosed. The spoiler extension includes a guide arrangement having a first guide element formed between the spoiler extension and a base body of the spoiler arrangement. Transfer of the spoiler extension is guided from a release position, in which the spoiler extension is detachable from the base body, along at transfer direction into a locking position, in which the spoiler extension is secured on the base body. The spoiler extension includes a securing element able to secure the spoiler extension automatically on the base body of the spoiler arrangement in the locking position.

A vehicle lower structure includes: an introducing port into which air is introduced, the introducing port being provided to a front part of a vehicle; an air outlet from which the air blows, the air outlet being provided to an underfloor downward of a bumper cover in a vehicle-vertical direction, the bumper cover being located at the front part of the vehicle; and a spat provided frontward in a vehicle-longitudinal direction of a front wheel, the spat including: a front wall protruding from a front edge of the air outlet in the vehicle-longitudinal direction toward a vehicle-downward direction in the vehicle-vertical direction; and a rear wall protruding from a rear edge of air outlet in the vehicle-longitudinal direction toward the vehicle-downward direction, and the spat opening at both sides of the air outlet in a vehicle-width direction.

A front spoiler arrangement for a motor vehicle, comprising a support component, a flow guiding component, which is positioned on the support component in a movable way between a further retracted position and a further extracted position, a guiding formation, which guides the movement between the two positions and a moving actuator, which is coupled to the flow guiding component by way of a coupling element, the coupling element and at least one component of either the moving actuator and the flow guiding component are coupled to each other through a connection arrangement, which has a surmountable detent formation, which separates from each other two possible relative operating positions between a component and the coupling element, i.e. a normal operating position and an emergency operating position, wherein a retraction movement of the flow guiding component in the direction opposite to the further extracted position beyond a retracted end position is mechanically prevented.

A vehicle includes a windshield having a top edge. The vehicle includes a roof extending rearward from the top edge of the windshield. The vehicle includes a sensor assembly supported by the roof, the sensor assembly including at least one of a LIDAR sensor or a camera. The vehicle includes a deflector movable from a lowered position to a raised position and supported by the roof at the top edge of the windshield forward of and spaced from the sensor assembly.

A spoiler lip for arranging on a front part of a vehicle is formed from a fiber composite plastic having at least one bidirectional reinforcing layer made of reinforcing fibers and a plastic matrix which contains an elastomer. The plastic matrix may also contain a thermoset in an embodiment of the spoiler lip.

A semitrailer underbody screen and wheel-set fairing kit comprises several panels and fairings for retrofitting on conventional semitrailers. A sectioned panel like fish scales covers the dozens of transverse I-beam cross-members positioned underneath conventional enclosed trailer floors, and carries on down the length of the underbody. A v-hull air deflector is set just beneath these panel covers, ahead of the semitrailer's undercarriage, suspension and tandem rear axle wheels. Such v-hull air deflector splits and aerodynamically “flows” the air being pushed ahead outwards to the sides and around the wheels. The tandem rear axle wheels themselves are completely boxed inside full fenders that cowl over the front, sides, top, and rear. Removable access panels are provided on the outsides of the full fender units for wheel and tire maintenance. The result is significantly less wind drag and noise at highway cruising speeds. Less drag means better fuel economy for the tractor operator.

An assembly for improving aerodynamics of a motor vehicle including a movable member forming an active aerodynamic dam positioned at a front end of the motor vehicle and attached to one end of at least one lever, wherein the at least one lever is connected to a motor that powers movement of the movable member, wherein the motor is operatively connected to at least one sensor configured to provide an input to the motor, the motor with a gear selector disposed within the motor that is configured to move a motor gear from a first gear position to a second gear position, resulting in the movable member being disposed in one of a retracted position, a transition position, and a lowered position, based on the received input.

An aerodynamics control system for a vehicle may include a dive plane assembly operably coupled to a front portion of a vehicle body, an actuator assembly operable to transition the dive plane assembly between a deployed state and a retracted state, and a controller operably coupled to the actuator to provide automatic control of the dive plane assembly via the actuator based on a selectable control mode. The selectable control mode defines a position of the dive plane assembly based on vehicle parameters measured while driving the vehicle.
