Maybe. What you are looking at is technically called the Nissan Concept 2020. If you've got Gran Turismo 6 on Playstation 3, you'll be able to drive it starting in July when it's available for download.
Initially, it was an excuse for Nissan's designers to go all-out on a supercar without having to worry about real-world practicality, but they did such a good job, it's possible you're looking at the early stages of a new GTR. This would be a good thing.
