grille block

I agree with Pale.Since the cooling system is credited for producing 12 % of overall aero drag,it may not be so important as to where its blocked,rather that its blocked.With airtight inlet and outlet ducts,the drag is virtually eliminated in some of the concept cars,and most race cars/boats/planes.
