Gran Turismo 5 Prologue[a] is a 2007 sim racing video game developed by Polyphony Digital and published by Sony Computer Entertainment for the PlayStation 3.

[5] The game has sold 5.09 million copies worldwide, making it the second highest-selling PlayStation 3 exclusive title after its successor, Gran Turismo 5.

When the game starts up, the player is taken straight to this interface, and the currently selected car is displayed on the screen in a picturesque real-life location.

The vehicle is set in a Full HD advanced 3D environment with a 360° camera and the GUI's real-time zoom-in function is enabled.

In the Japanese version, the 'My Page' interface includes: When the user's PlayStation Network account is signed off, online content related icons are disabled (1, 2, 3 and 4).

[18][17] From October 22 to November 30 three GT-TV exclusive HD videos featuring game producer Kazunori Yamauchi premiered in the demo: "First Impression: Lancer Evolution X",[19] "Tokyo Motor Show 2007"[20] and "GT-R Legend Inside Story part I".

[21] The demo was removed from the Japanese PlayStation Store on November 30[22] and its online functions ended on December 6,[23] however all issued VOD videos were later re-released in the game's retail version through updates, except the SD trailers.

The "GT-R Legend Inside Story (all parts)", "'08 Nurburgring 24h Introduction" and "First Impression Lancer Evolution X" videos stayed free-of-charge.

[34] Four circuits located in Japan, Europe, and North America are included in the original game, plus two fictitious tracks: The High-Speed Ring and Eiger/Eiger Nordwand.

In the absence of suitable roads in the real-life location around Kleine Scheidegg and the Eiger, the game developers created the track based on an actual hiking trail.

Spec II update[34] adds the Gran Turismo franchise's classic High-Speed Ring fictitious circuit (available in both forward and reverse version) which brings the total number of tracks to six (twelve different layouts).

[36] The Gran Turismo 5 Prologue free playable demo was the first PlayStation 3 release supporting both Dual Shock 3 controller vibration and racing wheels force feedback feature.

On February 20, 2008, Logitech announced a new Gran Turismo official wheel, the Driving Force GT to be launched in May to coincide with the game's western release.

Limited support for the Logitech G25 Racing Wheel is available; the wheel is not officially supported, but it is possible to re-map the button layout via the Driving Force Pro setup screen[38] and the clutch can be enabled by pressing the triangle button at the start of each race, as soon as the player has control of the car.

A free demo (グランツーリスモ5 プロローグ 無料体験版) was made available for download between October 20 and November 30, 2007[40] in the Japanese PlayStation store with the Suzuka Circuit and seven playable cars.

The remaining three cars (Mazda ATENZA Sport '07, Lexus IS-F '07 and Subaru Impreza WRX STI '07) were unlocked as each one was unveiled at the Tokyo Motor Show.

[43] The Black Mask was removed from the car section on October 23 to coincide with its official unveiling at the Tokyo Motor Show and was subsequently made available the following day.

The North American version of Gran Turismo 5 Prologue demo was unveiled at Sony's booth during the 2007 SEMA Show in Las Vegas, Nevada.

[46] Beyond the Apex is an 18-minute GT-TV documentary included in the Blu-ray version of the North American release of Gran Turismo 5 Prologue.

The "Moon Over the Castle" theme song from the Gran Turismo series is featured, arranged and performed by Vince DiCola.

[59] By December 2011, the games had sold 5.34 million copies; making it the second highest-selling PlayStation 3 title of all time being beaten by its successor, Gran Turismo 5.
