The video has Chinese subtitles only, no English.
H0ngcom believes Yamauchi said about this in video for China only, not in videos for other countries, as it could cause dissatisfaction among non-Chinese players.

h0ngcom think it is just a rumor, since Yang Wang is a joke for western language speakers, and more than one car of Xiaomi (SU7 and VGT) are more than enough for GT7/GT8 to recognize this nationality of car.
Edit : As of 8 January 2026, GT and Polyphony Digital Inc are still not yet confirmed about the Yangwang's GT7 appearances. Only Yangwang/BYD's claims only. Maybe the Yangwang is delayed to GT8.
