If you look at the upper right most concept in this image, they showcase the z proto design that we got with the horizontal cross beam through the grill that breaks it up.
I do really like the look of the large open grill as it looks like the 240z front with a bumper delete:
it might be nice to see a variation with the horizontal cross beam breaking up the bumper. Maybe as an option from the factory (which of course will never happen).
