Gran Turismo 6/Unused Content

The game files for Gran Turismo 6 include many leftovers from previous releases and demo builds, as well as several cars that were cut and/or unfinished during the development cycle.
Unless otherwise noted, all content on this page are derived from this The Cutting Room Floor page. In addition, attempting to access the following content in the game via modifications or cheat devices may cause the game to crash and hard-lock the system.
==Unused Cars==
These GT5 cars are absent from the game, either due to licensing, being cut during development, bugs/glitches, or other reasons, and only their entries remain in the database files.

There are a few interesting things of note:
*An entry for the Nissan March 12SR (GT Academy Version) '07 exists somewhere in the game files. It is unknown where the intended usage of this car would have originally been, but considering its entry is placed right before the Nissan Silvia spec-R AERO (GT Academy Version) '02, perhaps this was meant to be the car used in Round 1 of GT Academy 2012.
*The entries for the Nissan 370Z Tuned Car (GT Academy 2010) and the Nissan GT-R SpecV (GT Academy 2010) were originally two GT Academy cars that the player could obtain in Gran Turismo 5, but they are renamed in this game, denoted with the year they were featured.
*The Gran Turismo Red Bull X2010 5G were listed thrice in the game's files as there were originally three different variants of the same car present in Gran Turismo 5, each with different internal names (x2010_5g_12, x2010_5g_12_fin, and x2010_5g_12_dl).
==New, Cut Cars==
The car entries below never made an appearance in the game apart from their entries in the game's database files, either being cut due to development constraints, licensing issues, incomplete status, bugs/glitches, or other reasons.
*Ferrari 500 Mondial Pinin Farina Coupe '54
*BMW GSR Hatsune Miku BMW '12
*Audi R8 LMS Base Model '10
*Audi Quattro S1 Base Model '86
*Audi R18 TDI Base Model '11
*Red Bull X2014 Junior Color
*Red Bull Racing Kart 125 Color
*Hyundai N 2025 Vision Gran Turismo
*Toyota S-FR '15
*Alfa Romeo 6C Biposto Vision Gran Turismo 
Some interesting things of note with these cut cars:
*The Ferrari, as the entry's suffix (a bit incorrectly) states, won the Gran Turismo Trophy in 2012, but never appeared in this game, apart from only its entry in the database files.
**It later officially appeared in Gran Turismo 7.
*It appears there were additional base models planned for the Audi Sport quattro S1 Rally Car '86, the Audi R8 LMS - Team Oreca '10 and the Audi R18 TDI (Audi Sport Team Joest) '11. These cars have been dropped from inclusion into the game rather late into development, as thumbnails exist for these cars in the game's data files only.
*Variants of the Red Bull X2014 Junior and the Red Bull Racing Kart 125 were planned, in which speculating by the entry names, would allow the player to paint them with a custom color.
*An entry for the Hyundai N 2025 Vision Gran Turismo was added in Version 1.21, but the car was canceled and would later make its first appearance in Gran Turismo Sport.
**However, it was made playable at a special 2015 Frankfurt Motor Show build, where it debuted.
*An entry for the Toyota S-FR '15 car was added in Version 1.22, but never made it as a playable car in the retail version of the game.
**However, it was made playable at a special 2015 Tokyo Motor Show build.
*An entry for the Alfa Romeo 6C Biposto Vision Gran Turismo was added in Version 1.10, before Alfa Romeo pulled out of the Vision Gran Turismo project two updates later.

Additionally, a credit for Danica Patrick can be found in the game's licensing credits, although leftover data does not directly exist for her car. Based on the licensing credit, the car would have been likely named the 2013 Danica Patrick #10 GoDaddy.com CHEVROLET SS.
