Da Gran Turismo Sport blev afsløret ved Paris Games Week sidste oktober, så lovede udvikleren Polyphony Digital, at der ville være en beta "tidligt i 2016". Dog har udvikleren ved en nylig begivenhed fortalt <a href="http://www.videogamer.com/ps4/gran_turismo_sport/news/gran_turismo_sport_beta_has_been_cancelled.html>Videogamer</a>, at denne beta er aflyst.
Aflysningen skulle angiveligvis skyldes, at udvikleren kæmper for at nå udgivelsesdatoen d. 15 november, og at en beta-fase vil tage for lang tid:
Seriens skaber Kazunori Yamauchi har sagt følgende om aflysningen:
"That's something that I'm very, very sorry about. In order to do a beta test we have to make a gold master of the beta test code, and for us it actually takes as much effort as to finish the real master code of the actual game.
"Just because it's beta we can't just throw it out there. It's required that in order to do an open beta we have to create a proper master for it, and considering the release timing that we announced, we decided that we just don't have enough time to do two gold masters for the game. By omitting that it saves us about three months of time."
