A vehicle capable of traveling with a embossed surface of a directionality pattern includes a vehicle body and an under cover member. The under cover member is disposed on one or both of a front portion and a rear portion of a lower surface of the vehicle body. The embossed surface of the directionality pattern is formed on a plane portion of the under cover member. The embossed surface of the directionality pattern is configured to accelerate an airflow along a fore-and-aft direction of the vehicle body.

An active front deflector assembly for a vehicle capable of moving between an extended position and a retracted position or any position there between. The active front deflector assembly has a cross member for attaching to an underbody of a vehicle. The frame member also includes a plurality of slip joint connections for connecting to the underbody of the vehicle. The cross member is a fixed link of an actuator link assembly that has an actuator, drive link, floating link and a blade.

Provided is a bumper capable of improving a maneuvering stability of a vehicle. The bumper is a front bumper 7 to be attached to a front lower portion of a vehicle 1. Flow-straightening protrusions 31 each formed along a vehicular front-rear direction are provided on a lower portion of the front bumper 7 in a way such that they are aligned along a vehicular width direction across a region on an extended line 36 of a vehicular width direction inner end portion 2T of each of front wheels 2L, 2R of the vehicle 1. Thus, the occurrence of turbulent flows around the front wheels 2L, 2R can be restricted so that a vehicle stability can be improved.

An air deflection device of a motor vehicle includes an air deflection element and a displacement kinematic system. The air deflection element is displaceable by the displacement kinematic system from an extended deflection position, in which the air deflection element with a deflection surface in a front region of the air deflection element in a longitudinal direction of the motor vehicle diverts an airflow hitting the air deflection element in an underbody region in a forward direction of travel of the motor vehicle, into a retracted position. The air deflection element is displaceable by the displacement kinematic system rearwards in the longitudinal direction of the motor vehicle and upwards in a vertical direction of the motor vehicle and is pushable back in a direction of the retracted position in an event of an obstacle-related force component acting on the air deflection element in the longitudinal direction of the motor vehicle.
