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.
