Gran Turismo for Boys, a youth-focused Gran Turismo, was announced in November 2004 with a scheduled release date of 2005. The game missed the target release date of 2005. In September 2006, Kazunori Yamauchi confirmed the game was still in development. In April 2008, while discussing plans for Gran Turismo 5, Kazunori Yamauchi was quoted as saying, "we're hoping to make Gran Turismo for Boys a feature within GT5." In a 2013 interview  with GTPlanet, Kazunori Yamauchi said that the PSP version was a rendition of the "Gran Turismo for Boys" idea.
