A vehicle aerodynamic system with dual operating modes to modify downforce across varying speed ranges and driving conditions. The system comprises multiple fans positioned in airflow pathways and deployable skirts that interact with the ground surface. In a first mode, a complete set of skirts creates a fully sealed bounded region under the vehicle with central fans generating maximum downforce at low speeds on smooth surfaces. In a second mode, a subset of skirts (primarily side skirts) modifies the bounded region while all fans operate to provide downforce in dynamic driving conditions with uneven surfaces. The system includes a control mechanism to selectively deploy skirts and operate fans based on driving conditions, optimizing between maximum downforce at low speeds and improved performance over varying terrain at higher speeds.
