if you look at the spy photographs you can see the lower edge of the kidney grille. The base outline looks as if it flares out rather than today’s vertical outline.
The front will probably have, if that patent was correct a v-shaped facia far more dramatic than today’s car. They might create something around the top lights, a lower ledge maybe? Or even have a grille connecting shard from the headlights. The Grille of course will be larger and be the focal point. Maybe around this size ? But it will descend more.
Almost becoming those memes where the front of the car was the grille.
I think the shape owes more to the more dramatic outline seen on the XM and recently resized for the X3.
For the GKL models.
