Abstract: A vehicle including a first aerodynamic device extending from a body of the vehicle and movable between an extended position and a retracted position and an aerodynamic control module configured to determine wind conditions during forward movement of the vehicle and to move the first aerodynamic device between the extended position and the retracted position based on the determined wind conditions.

Abstract: A mudflap-integrated aerodynamic member for improving aerodynamic characteristics of a motor vehicle is described. The motor vehicle includes a vehicle body, a front wheelhouse, and a frame. The mudflap-integrated aerodynamic member includes a mudflap portion configured to attach to the front wheelhouse and cover at least a portion of the front wheelhouse and an elongated air strake attached to and projecting from the mudflap portion. The elongated air strake includes an elongated strake body extending longitudinally with respect to the vehicle body from an outboard edge contiguous with the mudflap portion to an inboard edge adjacent to the vehicle body.

Abstract: A floor pan includes a mid-body portion having a bottom wall. The bottom wall includes a forward end and a rearward end spaced from each other along a longitudinal axis. The mid-body portion of the floor pan is spaced above a reference plane, e.g., a ground surface, a first height at the forward end of the bottom wall, and is spaced above the reference plane a second height at the rearward end of the bottom wall. The second height is less than the first height to position the second end of the bottom wall nearer the reference plane than the first end of the bottom wall. The contoured shape of the mid-body portion provides an aerodynamic shield to direct airflow underneath components of the vehicle located rearward of the rearward end of the mid-body portion of the floor pan, as well as additional under-floor storage space.

Abstract: A rear wing for a motor vehicle includes a first end, a second end, and an aerodynamic surface including a pressure side extending between the first end and the second end, a first end plate is arranged at the first end, and a second end plate is arranged at the second end. At least one of the first end plate and the second end plate includes a selectively deployable aerodynamic surface.
