This is a concept car and not a production car but multiple working prototypes of it were made.
I was originally thinking this car couldn't fit in the game... however it might make sense to add in a dlc pack or as an endgame car
This car could also work in a japanese concept cars or high performance/supercars dlc along with cars like:
-Nissan Mid4 (Car that resulted in the r32 gtr)
-Jiotto Caspita which is a japanese mid-engined v12 supercar that did get to production
