I think the Cd 0.095 was for the blue model with the covered wheels:
It is quite a bit different than the Boxfish diesel prototype. It has a protruding nose (similar to the fish itself) and the rear fascia is significantly smaller than the Boxfish. It has wheels, with very large strakes and very large skirts. It has no cooling tract, and the underside is entirely smooth and it rises toward the rear.
Here's a bunch of screen captures from a video that Mercedes had made, showing the transition between the blue model to the Boxfish (so the color is also morphed) - start here and then use the arrows on the left side:

By the way, this blue model is the starting point I used when designing my CarBEN EV5.
