Well according to Renault-Nissan BV this is the final design!!
As with all cars that enter the "imminent production" phase, minor tweaks will always occur as more and more road testing is done. (I'm thinking either a spoiler will be a tweak, or is that odd line across the bootlid area an active spoiler?!?!).
Supposedly this is their final masterpiece.
In my honest oppinion . . . . . I love it.
The design is very 21st Century and the interior is very "techie".
Aluminium/Titanium/Stainless interiors seem to be the thing nowadays, and the interior of this GT-R is on par with the other modern masterpieces. The 350Z, Porsche, Noble M12, Zonda and such likes are all in the same technical design area. And so far they are all proving to be popular in their respective markets!
