Abstract: An airflow management cover for a vehicle subsystem arranged proximate a section of the vehicle to guide oncoming ambient airflow when the vehicle is in motion includes a convex body. The convex body has an exterior surface shaped to redirect an external portion of the oncoming ambient airflow around the vehicle subsystem to thereby minimize aerodynamic drag and reduce aerodynamic lift on the vehicle body. The airflow management cover also includes an aperture defined by the convex body and configured to exhaust a stream of a subsystem portion of the oncoming airflow to rejoin with the redirected external portion of the oncoming airflow after the subsystem portion of the airflow has passed across the subsystem. The airflow management cover additionally includes a fastening flange extending from the convex body and configured for mounting to the vehicle section. A vehicle having such an airflow management cover is also disclosed.

Abstract: A vehicle includes a vehicle body having a first body end configured to face oncoming ambient airflow when the vehicle is in motion relative to a road surface, and also having a second body end opposite of the first body end. The vehicle also includes first and second lateral body sides disposed generally parallel to one another. The vehicle additionally includes first and second side panels mounted to the vehicle body and configured to selectively deploy into ambient airflow aft of the second body end to become positioned along the respective first and second lateral body sides and retract from the ambient airflow. The first and second side panels provide an active lengthening of the vehicle body aft of the second body end to thereby reduce aerodynamic drag when both side panels are deployed and positioned along the respective first and second lateral body sides.

Abstract translation: 车辆包括：车体，其具有第一主体端，其构造成当车辆相对于路面运动时面对迎面而来的环境空气，并且还具有与第一主体端相对的第二主体端。 车辆还包括大致平行彼此设置的第一和第二侧身体侧。 车辆还包括安装到车体并配置成选择性地部署到第二主体端部的后部的环境气流中的第一和第二侧板，以沿着相应的第一和第二横向主体侧面定位并从环境气流中退回。 第一和第二侧板提供第二主体端部后部的车体的主动延长，从而当两个侧板沿相应的第一和第二横向主体侧面展开和定位时减小气动阻力。
