A vehicle includes a vehicle body having a first end configured to face oncoming airflow when the vehicle is in motion relative to a road surface and an opposing second end and an under-hood compartment provided in the first end of the vehicle body. An underbody extends between the first and second ends of the vehicle body and defines a space between the vehicle body and the road surface. At least one aerodynamic member is disposed adjacent a forward portion of the underbody and proximate to the under-hood compartment. The at least one aerodynamic member includes a housing and an airflow management device provided in an opening in the housing. The airflow management device is selectively positioned to direct the airflow from the front end of the vehicle into the under-hood compartment to improve vehicle performance.
