It looks like something Ricky Bobby dreamed up.

Also, I'd have to see more details, but the wide-open nature of the setup makes it difficult to perform effective fire-suppression in the event something "bad happens". It's interesting, but it looks to be in the "in progress" stage, rather than a fully developed cell ready for testing.

Finally: it's too bad they don't show the massive air handling at the front of the setup. To be honest, though, I wonder if this is an under-build picture rather than the final setup ready to perform testing. Normally, to move that quantity of air, you need to have a (large) closed chamber around the vehicle under test so that the air which passes the vehicle can be reducted back into the air handling inlet. The fact this is shown completely open & up in the air leads me to believe a drive-in room will probably be built around it -- that's how wind tunnels and other environmental chassis dynos are done in the industry. The operator dude would then be safely "removed from the action" behind some very heavy glass.
