A system for controlling fluid flow about a vehicle. The system comprises a fluid flow control device, an obstacle sensor for detecting obstacles, and a controller. The fluid flow control device has a body with at least one surface and an actuation means in operative communication with the surface. The actuation means is operative to alter at least one attribute of the fluid flow control device in response to a control signal. The controller has control logic for generating the control signal in response to the obstacle sensor.
