I think the rear translated really well from concept to production. The side and front not so much with the shorter wheelbase, lost of the deep and functional door vents, and the center stack nose.
1st one is based on the current 370z.
3rd one is from an old as dirty Infiniti concept.
The 2nd one in the middle is the only one that made from the teaser video.
