Drag reducing systems for vehicles are provided. In one aspect, a drag reducing system generally includes an airfoil rotatably couplable to the vehicle and configured to provide a lift force to the vehicle as a result of differential airflow velocity over the upper surface with respect to the lower surface. The drag reducing system may further include a flow alignment vane to rotationally align the airfoil to the direction of airflow. In another aspect, a drag reducing system generally includes an air vane hingedly couplable to a surface of a vehicle and configured to rotate from a first stowed position to a second deployed position. The air vane includes a flared leading portion to provide a force to bias the air vane toward the first position and a flared lateral portion to provide a force to rotate the air vane to the second deployed position.
