Abstract: Disclosed are active engine compartment venting systems, methods for making and using such systems, and vehicles equipped with an active engine compartment vent and control logic for operating the vent. A method is disclosed for regulating operation of an active venting device fluidly coupled to a vent in an engine hood of a motor vehicle. The method includes a vehicle controller determining if a calibrated vehicle venting condition exists, and determining if a calibrated vehicle speed condition exists. Responsive to determining that the calibrated vehicle venting condition exists, the controller commands the active venting device to transition to an open state and thereby unobstruct the vent and allow venting fluid flow therethrough. Conversely, in response to determining that the calibrated vehicle speed condition exists, the controller commands the active venting device to transition to a closed state to thereby obstruct the vent and restrict venting fluid flow therethrough.

Abstract: 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.

Abstract: A vehicle includes a vehicle body with a first body end configured to face an incident ambient airflow and an underbody section. The vehicle also includes a brake subassembly arranged proximate the underbody section and configured to decelerate the vehicle. An airflow regulation system includes a deflector moveably mounted to the underbody section and configured to regulate an underbody portion of the incident airflow to the brake subassembly. The system also includes a mechanism configured to change a position of the deflector to selectively direct the underbody portion of the incident ambient airflow to the brake subassembly and enhance aerodynamics of the vehicle body. The system additionally includes a first sensor configured to detect a predetermined operating condition of the brake subassembly. Furthermore, the system includes a controller configured to regulate the mechanism for selecting the deflector's position in response to the detected predetermined operating condition of the brake subassembly.

Abstract: According to aspects, an angled extension for an air curtain, the angled extension includes a base and a projection extending from the base. The base is configured to be attached to a front surface of a wheel well and is configured to be is disposed proximal to an interior side of an air-curtain outlet. The projection has a first end and a second end. The first end is configured to be generally angled toward an exterior side of the air-curtain outlet when the base is attached to the front surface. The first end is configured to deflect at least a portion of a flow of air that exits the air-curtain outlet to thereby inhibit contact between the flow of air and a front face of a tire. The second end is configured to be generally perpendicular to the front surface when the base is attached thereto.
