Disclosed are body panel strakes for improved vehicle aerodynamics, methods for making and methods for using such aerodynamic strakes, and motor vehicles employing aerodynamic strakes for reducing turbulent flow and developing higher static pressure at the rear of the vehicle. An underbody panel for a motor vehicle is disclosed. The motor vehicle includes a vehicle body with an undercarriage spanning between front and rear vehicle ends. The underbody panel includes a panel body that attaches to the vehicle body and covers a portion of the undercarriage. One or more elongated air strakes are attached to and project from the panel body. Each air strake includes an elongated body that extends longitudinally with respect to the vehicle and has an inboard-facing curvature. The air strake guides airflow traveling fore-to-aft along the undercarriage in an inboard direction to thereby increase static pressure on the rear end of the vehicle.

A cowl cross bar for a vehicle comprising a main cross bar disposed in front of a driver's seat in a transverse direction of the vehicle, a sub-cross bar disposed in front of a passenger seat in the transverse direction of the vehicle, and a center supporter configured to couple the main cross bar and the sub-cross bar to each other such that diametric centers thereof are disposed eccentrically relative to each other, the center supporter may include a main center support bracket provided with a connector to which a longitudinal end of the sub-cross bar is fixed, and a sub-center support bracket fixed to the main center support bracket, and having an insert hole through which a longitudinal end of the main cross bar is fixed to the sub-center support bracket.

A crash beam receiver for coupling to a crash beam for reducing the effects of a vehicle collision. The crash beam receiver includes a plurality of surfaces that are coupled together to form a hollow opening for receiving the crash beam. The crash beam receiver also includes a gate structure for providing a stopping point for the crash beam when the crash beam is inserted into the crash beam receiver. The gate structure includes a left gate, a right gate, and a protrusion structure that help to linearize the self-collapsing process of the crash beam in the longitudinal direction. The protrusion structure has a certain thickness such that the crash beam is caused to collapse inward toward its center in the event of a vehicle collision.

A workpiece includes a plurality of knots and webs, which are formed in one piece, of a sheet metal, in particular a steel plate. Each web extends between two openings from one knot to another knot, and at least three webs meet at each knot. A plurality of the webs has a cross section, which includes at least one hardened and one unhardened area.

Provided is a vehicle lamp including an operation unit configured to operate an optical axis adjustment bevel gear provided in a lamp to be axially rotated. An axial rotation force transfer body of the operation unit includes an operation rod operated to be axially rotated, a driving rod engaged with the gear, and a wire interconnecting the operation rod and the driving rod in an axial rotation direction, and the driving rod is formed of a metal which is hard to rust. The driving rod is formed by a metal/injection/molding (MIM) technique. A support member extends between the driving rod and the lamp.

A vehicle body includes a rocker panel elongated along an axis. The vehicle body includes a pillar fixed to the rocker panel and elongated in a direction transverse to the axis. The rocker panel includes a first flange and a second flange. The first flange and the second flange are on opposite sides of the pillar and spaced from each other in a direction parallel to the axis. The vehicle body includes a reinforcement fixed to the first and second flanges.

A reinforcing structure of a vehicle frame member includes: ribs that integrally connect standing wall portions, that are formed at a planar portion of a vehicle frame member, to one another, and that reinforce the planar portion; portions of gradually changing thickness that are formed at connected portions of the ribs with the standing wall portions; portions of gradually changing height that are formed at the connected portions of the ribs with the standing wall portions; first curved portions that are formed at the portions of gradually changing thickness; second curved portions that are formed at the portions of gradually changing thickness; third curved portions that are formed at the portions of gradually changing height; and fourth curved portions that are formed at the portions of gradually changing height.

A utility vehicle includes a plurality of ground-engaging members, a frame supported by the ground-engaging members, and a plurality of body panels supported by the frame. The utility vehicle also includes a radiator supported on a rear portion of the frame. Additionally, the utility vehicle includes an air intake assembly partially supported by an upper portion of the frame.
