Our best guess is that this is the next generation Samsung SM3. The car has similar styling themes to the extremely successful SM5/SM7, and the SM3 is definitely due for a refresh. Given SM5/7's success, it doesn’t surprise that the SM3 replacement apes the larger cars’ design themes. Given that the current SM3 rides on the previous generation Sentra/Almera/Sunny platform, it's probably safe to assume the new one would ride on the latest Nissan/Renault C-segment platform (FF-S). The Japanese domestic market version of this platform is the Bluebird Sylphy and in fact the Sylphy looks similar in profile and proportion to the car pictured here.
