I'm sorry, but that is pure genius in its combination of simplicity, aggression, elegance, and flair.

FWD is never going to have RWD overhangs, but usually companies like Mazda do a good job minimizing it in their proportions/designs.
If you mean the bright trim edge that runs the bottom boundary of the grille opening then I'd say NFW! That is the beautiful part of the grille IMHO. I'm no profound lover of brightwork, but it imparts a real elegance to this fascia design. It is quite necessary to me.
Personally I think Chevrolet, Honda, BMW, Toyota, Nissan, and Hyundai should be stealing away Mazda designers right about now.
I'm talking about the horizontal ribbing in the C&D rendering:
I think it would look better with a black mesh (even if it's mostly/completely fake). Like on this model doohickey, only in black, of course (or like the RX-3 pictured up there a few posts):
m235i : MS3 : 535i xdrive : civic hybrid
formerly of 07 MZ3 : 87 325 (x2) : 10 MS3 : 08 M3 : 14 WRX : 14 MZ6
The 3 is such an important car for Mazda that they can't screw it up. I am sure the end's results proportions will be fine even though I find this front to be a little too long.
