Project Gotham Racing 4 is a racing video game developed by Bizarre Creations and published by Microsoft Game Studios. It was released exclusively for the XBOX 360 in October 2007.
Project Gotham Racing 4 was accidentally leaked by a Peugeot press release for a competition for a car designed by a contestant to be featured in the game before the announcement by Bizarre Creations. The competition was won by Mihai Panaitescu with the Peugeot Flux.
Shortly after, the game was confirmed at X06, with a trailer titled Eclipse shown. The trailer was made available to download on the XBOX Live Marketplace. The car featured in the trailer is a Ferrari 599 GTB Fiorano. The song in the trailer is "Shadow" by The Prodigy remixed by Chris Chudley from Audioantics.
Microsoft announced at the 2007 E3 that Project Gotham Racing 4 would be released in September 2007. Bizarre subsequently said that game wouldn't be released "until it's done" citing reasons that they had spent a substantial amount of money and time on the game: "We feel like we've got more time [on Project Gotham Racing 4]. Last time round, we feel like we got the game ripped away from us", said Brian Woodhouse of Bizarre Creations.
Having since been acquired by Activision, Bizarre announced that Project Gotham Racing 4 will be their last game produced for distribution by Microsoft Game Studios.
Microsoft re-released the game under its "Classics" banner on 20 March 2009.
