Abstract: An active hood vent system for a motor vehicle includes a hood vent, having a closure displaceable between a closed position and an opened position, and a control module. That control module is configured to adjust the aero balance of the motor vehicle by opening and closing the closure. Further, the control module may be configured to close the closure and thereby minimize engine compartment air from entering an HVAC inlet of the motor vehicle when the current operating temperature of the motor vehicle is below a predetermined temperature requiring engine cooling, and a current motor vehicle speed is below a predetermined speed where airflow over the hood limits ingestion of engine compartment air by the HVAC inlet.

Abstract: An apparatus and method, according to an exemplary aspect of the present disclosure includes, among other things, providing a spoiler body having a plurality of tunnels defining an open area between the spoiler body and a vehicle exterior surface. Each tunnel has an uppermost wall having an airfoil section. The spoiler body includes at least one vehicle attachment area that is positioned between at least two of the tunnels.

Abstract: A front splitter assembly includes a front splitter having a first end and a second end, a first side splitter at the first end and a second side splitter at the second end. Each side splitter includes a contoured body. In one embodiment each side splitter includes an underwing extending between the extension section and the wicker section inboard of the end plate of the side splitter. A related method of improving stability and peak cornering speed of a motor vehicle is also provided.

Abstract: A front splitter assembly includes a front splitter having a first end and a second end, a first side splitter at the first end and a second side splitter at the second end. Each side splitter includes a contoured body. Each side splitter includes a dive plane feature that increases generation of downforce at negligible drag cost.

Abstract: A vehicle aerodynamic assembly includes a first end plate, an airfoil including an outboard edge portion contiguous with the first end plate, and a first drainage channel extending through at least one of the first end plate and the outboard edge portion of the airfoil. The aerodynamic assembly may be mounted to a deck lid of a vehicle.

Abstract: An active aerodynamic underbody shield system includes an underbody shield with a vent, a panel displaceable between a vent closing position and a vent opening position, an actuator to displace the panel and a controller for the actuator. The controller is configured to open the vent during vehicle braking to reduce downforce and therefore provide better lift balance adjustment for the motor vehicle. A method of reducing downforce and providing better lift balance adjustment during vehicle braking is also provided.
