Uhhhhhhhhhhhhhno.
At first the gt r was rumored to be a g35 semi-clone, and in a way it is.
But no powerplant has officially been released, and the link in the first post is the official exterior styling that it seems nissan has decided on.
All that's left to unveil is powerplant, suspension/brakes, and whether its going to be released as infinity or nissan. Hopefully the latter.
