A vehicle having one or more guide vanes for guiding airflow along a side of the vehicle. The guide vane(s) can be moved from a retracted position to a deployed position. The vehicle can include sills which can be displaced laterally outwardly and downwardly a retracted position to a deployed position.

Embodiments of the present invention provide an aerodynamic device for a vehicle, comprising one or more antenna elements arranged to extend from a surface of the aerodynamic device.

A backdoor structure for a vehicle, the backdoor structure comprising an upper window and a lower window, a rear spoiler disposed between the windows and projecting toward the rear of the vehicle, a backdoor frame supporting both windows and the rear spoiler, and a resin panel, wherein the resin panel comprises a window portion functioning as the lower window and a spoiler portion functioning as the rear spoiler, the window portion and the spoiler portion being integrated by resin molding.

In an undercover structure according to the present invention, a first cover part that is a lowermost part of an undercover has a first rear end positioned ahead of a front wheel axle. Further, a curved part with a predetermined curvature is formed at the first rear end of the first cover part in a side view. This generates a strong negative pressure in a region ahead of the front wheel axle 21. Accordingly, the flow rate of air flowing to each wheelhouse 23 decreases (the flow rate of the airflow between a road and a vehicle generated along the bottom surface of the first cover part 15a of the undercover 15 increases). This causes an attraction force that attracts the vehicle to a road surface to act on a vehicle body of the vehicle, thereby making traveling stability more excellent.

An airflow adjusting apparatus to be provided in a vehicle includes a flap and an airflow generator. The vehicle includes a wheel disposed to be partly protruded downward from a vehicle body of the vehicle. The flap is protruded, in front of the wheel, downward from the vehicle body. The airflow generator is configured to generate an airflow, and provided in an underneath of the vehicle body. The airflow generator is configured to generate an airflow. The airflow moves backward and downward of the vehicle and the airflow moves obliquely relative to a horizontal plane.

A computer program, method, and system for locksmithing. The computer program, method, and system receive vehicle information, obtain a key code for a lock based on the vehicle information, decrypt the key code to determine key specification data, and provide the key specification data to a user, such that a duplicate key corresponding to the lock can be formed.

The airflow generator is provided in an underneath of the vehicle body and vehicle-widthwise inwardly from the wheel. The airflow generator is configured to generate an airflow vehicle-widthwise inward, and backward of the vehicle. The airflow moves obliquely relative to a vehicle longitudinal direction when the vehicle travels forward.
