Pretty different from the 2010 mockups.
Having spent 40 yrs in the industry, I can attest to the transition from the styling studio, through engineering design, and then production engineering, LOL.
Now, those CAD renderings have some promise. Front fascia needs work but there actually are some nice angles, especially rear 3/4 view. Sort of an updated mating of a Lagonda with the best factory limos M-B ever made, the 600.
I suspect ZIL, being a heavy truck manufacturer since ‘91, was just incapable of anything that was not truckish. The production windows are not flush, the windshield in particular looks dated. The front fascia looks like a Freightliner. The lines of the sheetmetal aren’t contemporary, not much visual interest, just one character line running straight back. The sweep of the concept CAD was obliterated.
