It's a prototype of a Nissan Almera. It's based on Renault's compact car platform. The same as Renault's Megane. Rumor has it that the Sentra will be based on the same platform, so this could be a hint at what the next sentra could be. Sentra was a sedan and a coupe. There were also a hatch version called the NX back in early 90s. So there's no reason why they won't come out w/ a 5/3 door hatch, sedan, and a coupe. We'll just have to wait and see.
