Polyphony Digital har bekræftet en mængde nye funktioner i det kommende Gran Turismo 5, og der nævnes blandt andet nye vejreffekter, samt muligheden for at køre på stuntbaner. Dette og mere kan læses på den britiske Playstation-blog.
"Gran Turismo 5 will feature new game-enhacing graphical effects such as damage, night racing and weather. These innovations are twinned with the option to join millions of like-minded individuals globally within the Gran Turismo community and to find a driving experience to suit, whether that is taking on the Top Gear test track, chucking cars around stunt arenas, go-karting, creating and sharing your own track or intense head-to-head races".
