Here are a couple of spy shots from the set of Batman vs. Superman: Dawn of Justice that give us our first good look at the Batmobile!
The color appears to be just a dingy gray, not emblems or bat symbols are visible in either shot.
You can clearly see from the top down image how the canopy opens and what appears to be weaponry at the front of the vehicle. I’m wondering if those are wings at the back that deploy and this doubles as the Batplane!
