I actually think this new design could have a lot of potential. I hope the finished product looks something more like the below render (although headlight integration looks terrible).
I really like the current 7 but only because it has maintained good proportions, short overhang and typical BMW design cues. The front end lets it down slightly. The problem I have is that the grilles are not only big but they are tall. I wish they were wider like the old E38. That was a great design.
