Buckle up, because here's another car Infiniti is not going to build! The Concept Vision Gran Turismo was made for GT6, and you might be able to find its blueprints later on since, well, Sony makes Gran Turismo...
After Aston Martin, Chevrolet, Subaru and Nissan themselves, Infiniti's design team in Beijing also put together what they feel the "purest Infiniti GT" should look like.
Their Vision Gran Turismo comes with a mid-ship/trans-axle powertrain, giving the car a 45:55 front/rear weight balance. Its aero package is rather modest, having only diffusers on both ends and a Lambo-style rear spoiler for more downforce. The doors also came from Sant'Agata Bolognese, but overall, this car looks like something that could climb off the screens without too many changes.
If only Infiniti was interested in building such a machine.
