Gran Turismo 5 Prologue

Gran Turismo 5 Prologue is a prequel and taster of Gran Turismo 5 and has replaced Gran Turismo HD Concept. The addition of "Prologue" is a self-reference to Gran Turismo 4 Prologue, which was released a year before the full version of Gran Turismo 4. As of October 3, 2008, the game is now referred to as Gran Turismo 5 Prologue Spec III, which is the title of version 3.0 of the software. Gran Turismo 5 Prologue Spec III features 16-player online racing, over 70 cars (including tuned cars), 6 tracks, 12 layouts, a frame rate of 60 frames per second (during races, replays are displayed at 30 frames per second) and LPCM 7.1-channel high-definition sound.
