I hope the Z35 concept is as close to the production model as the 2001 Z concept. They barely changed a thing on that concept! What I hate seeing is some stunning concept that will obviously not get produced in that form. All that does is set everyone up for disappointment when a lame...
More mainstream to me means that Nissan wants it to sell in better numbers than the current Z which has had lackluster sales. That to me means turbo engine with better MPG and better pricing value than current 370Z.
