The interior shots are definitely "Project 370Z" that was unveiled at ZDayZ 2012. Nissan/NISMO brought it back for ZDayZ 2013 along with a Juke-R.
I didn't get any interior shots but here is a shot I got of the Project 370Z next to the Juke-R at Deal's Gap, NC during ZDayZ 2013.
I have more pics of the Juke-R here;
My Z with the Juke-R and Project 370Z if any one is interested.
