Gran Turismo 5 (also known as GT5) is the fifth edition of Sony/Polyphony Digital's racing video game series, Gran Turismo. Expanding on the Prologue version, which was first released in Japan in October 2007 and intended to give an impression of the final game, it will be the first of the main numbered series to feature on the PlayStation 3.
As found in the Prologue, and for the first time in the numbered Gran Turismo series, the game is set to feature cars from Ferrari, including the Ferrari F2007 Formula One World Championship car.[3] In addition to Prologue features, it will also include the 'Top Gear' Test Track from the BBC motoring show, and will greatly expand on the number of cars available, to over 900[4]. There will also be a 16 player online mode as in GT5 Prologue.
In an April 2008 interview, Kazunori Yamauchi revealed that 150 people had worked on Gran Turismo 5 for four years, with all of Polyphony Digital's 120 employees working on GT5, and the game costing 50 times more to develop than the original Gran Turismo.[1] He also confessed that GT5 might not be released until after 2009.[1] In a July 2008 interview with IGN, Yamauchi mentioned that at the moment, Polyphony Digital is focused on updates for Gran Turismo 5 Prologue and that Gran Turismo 5 may not be released until 2010.[
