Despite being delayed for over a year and a half, Gran Turismo 4 is considered by many to be one of the best games in the series, and one of the best racing games of all time. Featuring over 700 cars and 51 tracks, this one adds a lot more content than its predecessor, and was one of the 5 games on the PS2 to be capable of having 1080i support (one of the other ones being Tourist Trophy, also created by the same developers).
This game is also where the controversial Standard cars in the PS3 games originate.
And let’s not forget, that every single time you fail your license test, the game trolls you with the song “Oh Yeah” by Yello.

| Regional Differences|
Licensing and marketing choices resulted in lots of changes between regions, while the Korean version strives to add some local content.
| Mazda MX-5 Edition|
A special edition demo of the game, featuring the then-concept/pre-production version of the third-generation Mazda MX-5.
A hidden menu can be accessed by going to the Options screen and inputting L1, Up, L2, Down, R1, Left, R2, Right, Start, Start on the second controller; the sound heard when entering a menu from the main menu will then be played to confirm the right input. Note that the code must be entered each time the player visits the screen.
The two secret options associated with the input are named Secret and Monitor, both part of Miscellaneous part of the Options menu.
Secret (Special Settings)
- Specific Cars: Restricts the cars available in Arcade Mode to those in the Favorites list in Arcade Mode. This option is not available if no favorites have been yet defined.
- Specific Courses: Restricts the cars available in Arcade Mode to those set in Course Registration Settings, which is primarily an option related to LAN mode.
- Specific Opponents: Restricts the opponent cars chosen in Arcade Mode to those in the Favorites list in Arcade Mode.
- Specific Makes: Allows the game to be set to only feature a certain manufacturer. When this is the case, you cannot enter Gran Turismo Mode, and the title screen's background movie is changed to a generic one with the chosen manufacturer on top of the game logo on the title screen. Selecting none, the default option, reverts to normal gameplay. An example can be seen on the MX-5 Edition's title screen.
Monitor (Detail Monitor Settings)
This portion of the menu allows you to adjust the camera and the display of the screen during races.
- Flag: Four flags can be chosen (FLAG_NONE, FLAG_ROTY, FLAG ROTX, and FLAG_ROTX|FLAG_ROTY). These appear to deal with settings on each horizontal/vertical axis, but it does not appear to affect anything.
- Zoom: Adjust the field of view, in range of 0.00 to 3.00.
- Distance: Adjusts the distance from the viewpoint of the player's camera between 200 to 1200 millimeters; the default setting is 276 mm.
- Width: Adjusts the width of the display area, between 200 to 600 millimeters.
- Height: Adjusts the height of the display area, between 200 to 400 millimeters.
- Aspect: Adjusts the pixel aspect ratio, between 0.00 to 2.00.
- Overscan Factor: Obvious what it adjusts, the value is 0.00 to 2.00.
- Border Width (Left, Right, Top, Bottom): Adjusts the width of each side of the screen border in millimeters. The range of each is 0 (default) to 300 millimeters.
The default settings depends on the selected aspect ratio mode:
|Border Width (all)||0||0|
Unused Car Assets
Ford GT (No Stripe) '05
While not normally accessible in Arcade Mode (except in two-player races, if loaded from a GT Mode save), the Ford GT (No Stripe) '05 has an Arcade Mode thumbnail.
Ford Model T Tourer '15
There is an unused alternate banner for the Ford Model T Tourer '15 featuring an alternate logo placement, with it's internal name suggesting that a 1914 model was considered for inclusion instead.
|model_t_tourer_14 (unused)||model_t_tourer_15 (used)|
Nissan 350Z Gran Turismo 4 Limited Edition (Z33) '05
Verify car names; only the USDM one is verified and even then it's from GTPSP.
There are two alternate logos for what can be described as Japanese and American equivalents of the Nissan 350Z Gran Turismo 4 Limited Edition (Z33) '05 (since Nissan marketed the GT4 Limited Edition car simply as the 35th Anniversary model outside Europe); the model that appears in all versions of the game is the European model, evident with the European-sized license plates and the fact Nissan only marketed the model as such in Europe.
Of note is that string for the American model appears in GTPSP, but not the Japanese model.
|Nissan 350Z 35th Anniversary (Z33) '05||Nissan Fairlady Z 35th Anniversary (Z33) '05|
Additionally, there is also an entry for an engine that would have been used by the Japanese and American 35th Anniversary model.
|Peak power (rpm)||6400||6200|
|Rev limit (rpm)||7000||7500|
Chevrolet Corvette (C6)
A car banner for a Chevrolet Corvette (C6), named "corvette_c6_coupe_04", can be found in the game's car banner logos folder (GT4.VOL/piece/car_logo2). The logo asset itself appears to be a simple placeholder containing the car's internal name as mentioned, created with one of the game's default white sans-serif fonts, similar to the Vemac logo asset.
The C6 Corvette would debut in the series with the Z06 model in Gran Turismo 5 Prologue.
Unused Race Events
There is an unused race event in the game called Road Going Formula (misspelled as "Road Going Fomula Cup" on the flyer card; the word "Cup" is also missing on the event's actual name). Judging from its filename (ex_roadgoing_0000), this was planned to be an Extreme Hall event. The event is present in the game's event database, and completing it would have awarded the Caterham Seven Fireblade '02.
- Description: "A heated battle between formula machines that race on public roads." (European English)
- Event Type: Single Race (5 Races)
- Cars Permitted: No restrictions
- Rival Cars:
- Suzuki GSX-R/4 Concept '01
- Race #1: Laguna Seca Raceway
- Number of Laps: 3
- Rewards Table:
Position 1st 2nd 3rd 4th 5th 6th Credits 15,000 Cr. 7,500 Cr. 5,000 Cr. 4,900 Cr. 1,500 Cr. 800 Cr.
- Race #2: Grand Valley Speedway Reverse
- Number of Laps: 3
- Race #3: Tokyo R246
- Number of Laps: 2
- Race #4: Suzuka Circuit
- Number of Laps: 2
- Race #5: Fuji Speedway 2005
- Number of Laps: 2
- The event's flyer features an image of the Caterham Seven Fireblade '02 (along with the only opponent car for the event, the Suzuki GSX-R/4 Concept '01), which is not actually defined as an opponent car due to the car having a "special" (restricted to Time Trials and 2-car races in the Arcade Mode, due to high polygon usage) status.
Unused Driving Missions
There are 34 Driving Missions in this game, divided into four mission genres (The Pass, Three Lap Battle, Slipstream Battle, and One Lap Magic, which is divided into two parts for prize cars purposes). However, it seems that there were plans for a fifth type of Driving Missions called Chase Battle, each with six challenges, all of them seemingly themed after touge (mountain pass) racing, and are set on "rally" city courses, which typically is designed for two cars on the grid.
|#||Event Name||Course||Description Text (US English)|
|35||Chase Battle: Lancia Rally Machine Showdown!||Citta di Aria||This is a chase battle where you start with a fixed time difference between you and your opponent. If you can reduce this time difference within one lap you will win, but if this increases you will lose. The first round is a rally car contest on the Italian street course.|
|36||Chase Battle: Lancer Evo Showdown!||Costa di Amalfi||Chase the next level of super rally prototypes in a rally version of the Lancer Evo VIII. Make up for the massive difference between the competing cars with your driving skills.|
|37||Chase Battle: Peugeot Rally Machine Showdown!||George V Paris||This is a night-time French Rally car showdown, taking place in the street stage that passes through the Arc de Triomphe in Paris. You are at the controls of the monster 205T16, racing against the latest generation of 206 rally cars.|
|38||Chase Battle: Prototype Showdown!||Citta di Aria Reverse||Two monster cars with a total of 1600 horsepower catapult through the distinctively narrow streets of an old Italian town. Only Gran Turismo brings to life this dream battle in this dream situation.|
|39||Chase Battle: BMW 12-cylinder Showdown!||Costa di Amalfi Reverse||This is a serious race between the 2 Le Mans winners boasted by BMW along the Amalfi Coast on the Tyrrhenian Sea. The only thing that can catch the higher level V12LMR is the driver's technique.|
|40||Chase Battle: Mercedes Showdown!||George V Paris Reverse||This is a course setup that runs from Champs d'Elysees through George V Avenue and under the Arc de Triomphe in the quiet residential streets. This is an evenly matched battle on the street between 2 racing Mercedes.|
These missions also have description text for the pre-race screen, although in the US version of the game, Mission 36's and 38's pre-race text are duplicates of Mission 35's and 37's, respectively; as such, the text dumps for Mission 36 and 38 are from the European version of the game.
|35||Here your rival is a Lancia Delta S4. As this is one of the cars from the period of inception of 4WD, the understeer is so severe it is difficult to turn, yet it has intense speed on the straights. You will give chase in a finely-balanced HF Integrale.|
|36||Although your rival has better performance across the board, from horsepower and weight to cornering ability, it seems that the tuning settings are imbalanced. Take full advantage of the resulting hesitancy in the rival car's driving to snatch a victory.|
|37||This is the 205 T16 monster rally car, fitted with a 350 horsepower mid-mounted engine. Although this offers overwhelming speed on the straights, it may not do so well on tight turns. Try to prevent your rivals from closing the gap on corners and breaking away from you.|
|38||Open and closed canopy - although with a difference in style, both are among the world's fastest prototype machines. For cars with downforce, the key to winning is your recovery technique when a car has closed the gap.|
|39||The key to the Amalfi Circuit is making small turns to the inside of the numerous stop-and-start hairpins without overrunning the corners. Drive through the few high-speed corners without error, and pray for more power....|
|40||On this course it is hard make a difference in position using corners as the course layout is too narrow. The timing of when you hit the accelerator when you come out of a small corner is everything in this challenge. Don't forget precision in handling, and avoiding collisions with the walls.|
The license-specific tracks in this game consists of the variations of the Driving Park Gymkhana (the normally accessible version is named gymkhana_free) track and the slalom variant of Fuji Speedway (before the 2005 redesign).
- fisco_slalom: Used in IB-6 and IB-7 License tests.
- gymkhana: Used in the B License Coffee Break test.
- gymkhana_maze: Used in the S License Coffee Break test.
- gymkhana_spiral_r: Used in the International B License Coffee Break test.
- gymkhana_spiral: Used in the A License Coffee Break test.
- gymkhana_super: Used in the International A License Coffee Break test, although the name suggests that it was originally planned to be S License's Coffee Break challenge.
Drivable Photo Travel Tracks
Test further the remaining tracks, or at least describe what xTimelessGaming did on the video below.
As it turns out, you can drive on some of the places used in Photo Travel mode by cheat methods as they are treated as tracks by the game. However, you can only go so far, as it's very limited on what you can actually drive on.
The following locations has been tested:
- Beacon Hills: Only some of the roads can be driven before the player hits the invisible walls.
- Brooklyn: A very short map; the player can only drive on the dock you're on, as there are barriers surrounding it.
- Grand Canyon: Like the Brooklyn map, by the size of the map here, it really shows how far you can go, which isn't much. You can drive on and off the cliffside though, so that's cool. The course map for this track is taken from the namesake rally course.
- Times Square: It is possible to go down most of the main strip here. The map is actually placed to the right of the New York course, as its logo is shown before you start and the map is displayed while driving.
- Tsumago: Short and cramped is the best way to describe this one, and you can only drive on some of the village's roads, not all.
Grand Canyon Short Track
A track icon for Grand Canyon Short Track can be found in the game's track logo folder (GT4.VOL/piece/crs_logo). This rally track was used only in a Driving School test in Gran Turismo 4 Prologue and did not return for the game.
Unused Wheel Codes
Although aftermarket wheels do not usually appear in Today's Special section of GT Auto's Wheel Shop, they do have names in that format (two first letters signifying manufacturer, and a four-digit identifier number; in most cases, the first digits are always 02).
|Wheel Filename||Wheel Name (Wheel Shop)||Wheel Name (Today's Special)|
Three tunes seem to be either unused or included in a very early patch of the NTSC-J (Japanese) version of the game. These are the following tunes:
North American Reprint
A late Greatest Hits reprint of the North American version with a version number of 2.00 in the SYSTEM.CNF file (as opposed to 1.01 in the original release and earlier Greatest Hits copies). The SYSTEM.CNF file has a modification date of June 26, 2007, suggesting this is a late rerelease indeed. The only changes in this version are alterations to the following course files inside GT4.VOL:
The actual impact of these changes is unknown.
Mazda RX-8 Concept (Type-II) '01
Although the car is available in multiple colors in Arcade Mode, when the Mazda RX-8 Concept (Type-II) '01 is obtained from earning all silver times in the International B License, the color the player receives is always in RX-8 Yellow color, leaving all other six colors seemingly unused in GT Mode. All other license prize cars available in multiple colors, such as the Volkswagen Lupo 1.4 '02 (from finishing the National B License) and Jensen Interceptor MkIII '74 (from getting all gold in International B License), are given to the player in any of each cars' color choices.
Because of this oddity, the car's other colors were left seemingly forgotten in the later games, they became hidden and unused in the PSP game and completely absent from the PlayStation 3-era games of the series.
Toyota 7 Race Car '70
In Arcade Mode, it is possible to drive the Toyota 7 Race Car '70 on dirt or snow tracks, even without using the car switch glitch. However, doing so results in the car's wheels appearing to be hollow, with the car being difficult to drive as a result; additionally, when the replay is played back, the tire information is shown as "-/-".
If this is done in 2 Player Battle with Player 2 choosing the car in question, the tires will appear properly (although not fully fitting the car in size), with proper drivability.
Mazda RX-8 Road Gong Concepts/Mazda MX-5 '05 Purchase Prices
Both Mazda RX-8 road going Concepts, the Mazda RX-8 Concept (Type-I) '01 and the Mazda RX-8 Concept (Type-II) '01 are the only two concept cars in game that will not appear in the dealership. Other than this peculiarity, they can be bought for free if they are forced to appear in a dealership. Unlike for all of the other unbuyable cars (labeled as "Not for sale" if the player attemps to buy it, and the impossibility of highlight "Buy"), both will have a price of zero Credits (Cr.-- in game) and available for the purchase. By this method, the player could achieve also the other six colors of the Type-II Concept. The same thing happens also for the Mazda MX-5 '05 in the Online version of the game.
Citta di Aria in Arcade Mode
For some reason, Citta di Aria is the only track that cannot be used in Arcade Mode's Single Race mode. However it can be selected in Time Trial and 2 Player Battle modes.
