Im pretty sure that’s cactus. It’s too light to be Area 51. I think it’s just a filter they put on the image that makes it look blue. Heres a video of it:
What is this to the right? Cactus or Area-51? It is not bright enough to be velocity blue. I think this may be Area-51 as in the other promotional photos where they list the vehicle being cactus gray it is lighter than this from what I can tell. Just my opinion.
