The interior isn't looking that bad. I won't say that they are trying really hard to re-produce the interior of the concept verbatim, however, the main design cues are still there, just toned down a bit.
If you compare the two closely, you can see that the general gist of the concepts interior is still there. The black portion of the production dash shares a similar shape with the production version, and once the center stack trim is in place, you will see that the same flow still exists. The dark grey inset portions from the concept are replaced with the wood trim areas, and while not as deep of an inset, they are still behind a lip, giving a sense of an overhang. It is also apparent that the top of the dash continues over the doors, just like in the concept.
I am a little disappointed with the lower portion of the dash, it is not as clean cut and sculpted as the concept, nor does it share a similar shape.
I don't think we will be seeing all of the "bling" on the center stack as we see in the concept, however, by the looks of the missing trim, they do have something similar planned...
Overall, not a horrible effort on their part, but, obviously not as extreme as the concept.
