I'm not sure about that. Typical 18 inch fans turn at about 1,000 rpm on low speed and move about 2500 cfm. Car wheels turn at about 800 rpm at 60 mph. Wheels are probably not going to be as efficient at moving air as a dedicated fan, but I don't think it is out of the realm of possibility for a turbine design wheel to move 500 -1,000 cfm at 60 mph.
Of course we don't know if these even
are turbine design wheels, but the effect of wheel design on airflow doesn't seem to be one that can be dismissed out of hand.
