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.
