I can see a mild hybrid setup that would have start stop function. That wouldn't be so offending on weight. A diesel however I just don't see it. Also the triple projector setup in te headlights is over the top. That would be cut for production.

I would like to see them come up with "Z" emblem. I do not like the Nissan logo. I mean the Mustang and Corvette and most respectable sports cars have their own emblem.
