Gran Turismo 5 Prologue

Gran Turismo 5 Prologue is a predecessor and trial version of Gran Turismo 5 and has replaced Gran Turismo HD Concept. The addition "Prologue" is a self-reference to Gran Turismo 4 Prologue, which was released one year before the full version of Gran Turismo 4. Since October 3, 2008, the game is now called Gran Turismo 5 Prologue Spec III, which corresponds to 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 (replays are displayed at 30 frames per second during races) and LPCM 7.1-channel high-definition sound.
