Not to be the party pooper here, but that website is pretty much not official in any way. Most of the articles are questionable at best (here's one:
2017 Nissan GT-R R36 Specs | 2017 / 2018 Nissan and Infiniti Cars). It's a shame because, with the low $20k pricing speculation, this seemed like the perfect affordable daily driving car. I love the look.
Nissan originally came out and said they'd produce this car in its RWD form. They then backed off this claim, with profitability as the reason. That turned into Nissan hinting at a FWD version and, as of last year, backing off the concept completely to focus on other areas.
This car may hit production at some point (unlikely as a RWD car), but I wouldn't hold my breath (I'd sooner expect the new Z than this car). This car is very much a concept--nothing more. Even if it does hit production, I'd guess it won't look anything like the concept.
