Editing Gran Turismo 5 (section)

==Development==
The game was first revealed at E3 2006 under the name ''Vision Gran Turismo''. In an April 2008 interview, Yamauchi revealed that 150 people had worked on ''Gran Turismo 5'' for three years, with all of Polyphony Digital's 120 employees working on ''GT5'', and the game costing 50 times more to develop than 1997's ''Gran Turismo,'' with Yamauchi later disclosing that ''Gran Turismo 5'' had cost $60 million to develop. At Sony's E3 2009 Press Conference, a trailer for ''Gran Turismo 5'' was shown, revealing both the inclusion of NASCAR and WRC but no release date was revealed. In an interview with Eurogamer, Yamauchi said that "We've actually reached a point where we can probably release [GT5] anytime, except that you can also keep working as long as you want to as well, it's just a matter of timing." According to the official magazine at Tokyo Game Show 09, Gran Turismo 5 is 65% complete.

The GT5 Time Trial Demo was released on December 17, 2009 on the PlayStation Network, and is only playable while online. It features stock and tuned versions of the Nissan 370Z. The track featured in the demo is the Indianapolis GP circuit and is new to the ''Gran Turismo'' series. It has recently been announced that users will be able to output HD replays onto YouTube.
