A large grille opening is not needed for a BEV. I imagine the next generation Mach-e will at least tone down, if not eliminate the vestigal grille, best to eliminate it altogether for smoother aero. Ransom Olds installed buggy whip holders for years on the Curved Dash Olds because folks were used to seeing one on their horse drawn buggies. As automobiles started overtaking horseless carriages the whip stands went away. As BEVs become more familiar, grilles will fade away, too, IMO.
