1. A passive vehicle drag reduction system comprising:
an airflow capture inlet having an air entry window, the airflow capture inlet defining an airflow capture inlet direction;
a flow consolidating conduit that extends from a consolidating conduit upstream end at the airflow capture inlet, to a consolidating conduit downstream end;
an air driven rotor assembly having a rotor assembly inlet located downstream of the consolidating conduit downstream end, and an air driven rotor,
the rotor assembly inlet defining a rotor airflow inlet direction,
the air driven rotor having a laterally extending rotation axis transverse to the rotor airflow inlet direction, a plurality of air driven blades, and one or more air redirecting blades interior of the plurality of air driven blades, the air redirecting blades defining one or more rotor airflow outlet directions substantially parallel to the rotation axis; and
one or more flow exhaust conduits downstream of the air driven rotor assembly.
