Gran Turismo Concept is a spinoff of the main series. As the name indicates, it features concept cars (of which most would appear on the fourth game). Also, Americans got screwed over; they only got a less feature-filled version in the form of Gran Turismo: Nissan 350Z Edition.

Hmmm...
To do:
Oh boy.
  • Check if any more unused tracks exist.
  • Document the tracks more thoroughly; the video to most of the courses listed so far is here: https://youtu.be/TbZYAtuOg-Y while the video for the Demo_UpDown track is here: https://youtu.be/UTKcx8STOLU
  • Add more to the 350Z Edition and Copen Edition, if need be. Including any unused material.
  • Check for and add any more 'special editions'.
As a reference to any editors, there's a big research thread here: https://www.gtplanet.net/forum/threads/xenns-gt-concept-research-topic.275216/ , which can be used to document most unused material or version differences.

Unused Tracks

Surprise! Like most games in the series, there's unused tracks! However, most of the tracks found are in a very unfinished state, only having the track map and very little elevation done. These include Tsukuba Circuit, Twin Ring Motegi, and even Suzuka. There are however, some tracks that were somewhat finished that went unused listed below:

  • Motegi South: A gymkhana-like course that the developers probably used to test cars. It's likely that the course was going to be used as a free run course or one of the game's bonus events, but was likely scraped in favor of the gymkhana course that was later used in Gran Turismo 4.
  • Laguna Seca: An earlier version of the course used in Gran Turismo 4 Prologue. Set at dusk, and has more similarities to its Gran Turismo 3 counterpart.
  • Demo_UpDown: An odd, rally-like course using a layout similar to Tsukuba Circuit that is set at a forest with some big elevation bumps. Purpose unknown.
  • Test Course: Similar to the GT3 version, but for some reason, cars have really bright front lights here.
  • ss_snow: A circle-like snow course with very little to it. Judging by the "ss" in its title, there is some reason to believe that this was supposed to be a photomode track, much like the Togakushi Kogen location in Gran Turismo 4.

Unused Cars

Hmmm...
To do:
Check with '01 Tokyo and '02 Tokyo-Seoul, one of the versions even have the Mustang Cobra R.

As this spinoff is based on Gran Turismo 3: A-Spec's engine, some unused cars from that game can be found here. However, most of those cars had to have most of their data deleted to make room for the newer ones, so they remain inaccessible. Some cars can still be accessed though, along with a few others exclusive to this game. In the game's files you can find "Tuned" versions of cars, but actually don't show any differences compared to standard version. This unused car list is based on 2002 Tokyo-Geneva release.

Hidden Manufacturers

Acura

Acura appears in Tokyo-Geneva disc as an unused manufacturer, meaning a possible North American release was planned.

  • Acura DN-X: The American version of the Honda Dualnote; would later appear in the American version of Gran Turismo 4.
  • Acura NSX-R Prototype: Same with the Honda version other than badging. (Honda never sold the NSX Type R in the USDM market).
  • Acura NSX-R Prototype LM: As above, complete with badge changes similar to the US version of the NSX-R LM GT2 in the first Gran Turismo.
  • Acura NSX-R Prototype LM Load Car: As with the regular NSX-R Prototype. "Road Car" is misspelled, strangely.
  • Acura RSX: The production version of the RSX, with different color choices.
  • Acura RSX LM: A rebadged Honda Integra LM Edition (Honda Integra Type-R Touring Car in later games) with Acura logos.
  • CL 3.2 Type S: Unchanged from GT3.
  • INTEGRA Type R: Unchanged from GT3.
  • NSX (1997): Unchanged from GT3.

  • Spider 3.0 V6 24V: As above.

Fiat

  • Barchetta: Named "barchetta_gd_00" in the game's files, suggests that it is actually the Giovane Due model (in fact "gd" is the initials), would later appear in GT4.
  • Coupe Turbo Plus: Unchanged from GT3.
  • Punto HGT Abarth: Brand new model, would later appear in GT4.

Opel/Vauxhall

JP/KR Version Cars

There cars are unique to GT Concept 2001 Tokyo and 2002 Tokyo-Seoul; some cars would have name or badging changes in Tokyo-Geneva:

Honda

  • CIVIC TYPE-R 2001: Replaced by the 2002 version. The Championship White color was replaced with Satin Silver Metallic.
  • HONDA Fit W: In Europe it is known as the Honda Jazz. Both are the same also with color options.
  • S2000 2001: The S2000 was replaced by the European version of the same car, badged as "HONDA S2000" and not simply "S2000" (possibly due to European trademark registration issues) and having color options.
  • S2000 Type V 2001: Same story as the standard S2000, the European Type V replaces the Japan spec Type V.

Hyundai

  • TUSCANI: The Korean domestic market version of the Coupe, with less color options: Smart Silver, Noble White, Sunny Yellow, Samba Red, Carbon Blue and Ebony Black.
  • Verna Rally Car: Korean version of the Accent Rally Car, otherwise identical.

Mazda

  • MAZDA ATENZA: Appears only in the original release of the game together to own LM version. Same colors as the Mazda 6, the European version of that car.
  • MAZDA ATENZA LM: Is totally different to the Mazda 6 LM. Has a color choice and a different scheme.

Nissan

  • Fairlady Z: Replaced by European 350Z model in Tokyo-Geneva.
  • Fairlady Z Version R TwinTurbo 2 by 2: Rebadged as 300ZX outside Japan.
  • Fairlady Z Version S TwinTurbo 2seater: Rebadged as 300ZX outside Japan.
  • PRIMERA 20V: Is the model present in the two previous releases, with less colors.

Toyota

  • ALTEZZA Gita AS300: The Asian version of the Lexus IS300 Sport Cross. Has the same colors.
  • SOARER 430SCV: As always Toyota luxury cars are replaced by their own Lexus counterpart. The Soarer have different colors.

US Version Cars

Because all cars for all regions are stored in the disc, the game data also subsequently includes American versions of the cars, which would be used if the game had a general American release.

Honda

  • S2000 '01: USDM model, later used in GT4.
  • S2000 Type V: USDM model, later used in GT4.

Lexus

  • LEXUS IS: A "proper" USDM Lexus IS, as opposed to what is effectively a rename of the Altezza AS200; later used in GT4.
  • LEXUS IS Sport Cross: Same as the European model, with color name changes.
  • LEXUS SC430: USDM model with color name changes.

Nissan

  • 350Z LM: 2002 model year, has Exxon decals as with usual practice of replacing Esso (used in Fairlady Z LM) with Exxon logos in American releases.

Completely Unused Cars

Honda

  • NSX-R LM Hashinken Version: Effectively a duplicate of the NSX-R LM Prototype Road Car, except only available in silver.

Hyundai

  • Tiburon GT V6: No-showed Tokyo-Seoul for no reason, would later appear in the American version of GT4.

Lexus

  • LEXUS SC430 (China spec): Contains different color choices compared to European/American SC430s and the Japanese Soarer, probably intended for Asian Tokyo-Geneva release.

Mini

  • MINI COOPER: The base model Mini Cooper, would later appear in GT4.
  • MINI COOPER-S Rally Car: A unique rally car, featuring appearance inspired by the old, Monte Carlo Rally winning Mini Cooper S.
  • MINI ONE: The true base model BMW-built Mini, would later appear in GT4.

Nissan

  • 350Z RAZO version: A RAZO sponsored 350Z.
  • GRANTURISMO GT-R V-specII(R34) PaceCar: Used only in guided Course License events when the setting to use pace car is set.
  • SKYLINE 350GT: Featuring different color choices, would later appear in GT4.

Peugeot

  • 106 S16: Returning car from GT2 with newer model year, would later appear in GT4.
  • 206cc: An all-new model that would later appear in GT4.
  • 406 Coupe: Another returning car from GT2 with newer model year that would later appear in GT4.

Volkswagen

  • Polo GTi: Just plainly unused for no reason; would later appear in GT4.

Unused Cars from GT3

All of the unused cars from Gran Turismo 3: A-spec (the Stratos, Stratos Rally Car, JLOC Diablo, 911 (996) GT3, the hidden Roadsters, and the duplicate Lancer Evolution VI Rally Car) are still here, except for the "sample" cars. In addition, the six F1 cars are still in this game, but with altered redline: 15,000 rpm (18,000 rev counter) for naturally aspirated F1 cars and 12,000 rpm (14,000 rev counter) for turbocharged ones.

"Tuned" Duplicates

Hmmm...
To do:
Get file names and table them like the PS3/PS4 era games do.

Some older cars (appearing first in GT3) also have "tuned" duplicates, for some reason. The cars in question are:

  • NSX-R Prototype LM Road Version:
  • SAVANNA RX-7 INFINI III(FC Tuned)
    • This car appears twice, one named SAVANNA RX-7 INFINI III(FC Tuned) 1 and SAVANNA RX-7 INFINI III(FC Tuned) 2.
  • Mine's Skyline GT-R N1 V-spec(R34)
  • NISMO GT-R LM Road Car(R33 Tuned)
  • 180SX Type X (Tuned)
  • SILVIA K's 1800cc(S13 Tuned)
    • This car appears twice, with the other having the name of SILVIA K's 1800cc(S13Tuned) (note the missing space between "S13" and "Tuned").
  • SKYLINE GT-R V-specII(R34 Tuned)
  • Spoon S2000 Race Car

Unused Bikes

Suprisingly, in the GT3.VOL file (in which main things like car data are stored), there exists a folder called "bike". Within that folder exists a few unused models for 2 bikes named "cbr600f4i_01_pdiver" (a Honda CBR600F4i with Tourist Trophy logos) and "yzr500_99_antena3" (Team d'Antin's Yamaha YZR500 from the 1999 MotoGP season), along with a few models for a rider named "man". Neither motorcycle would appear in Tourist Trophy, the customized CBR600F4i being replaced with a 2005 CBR600RR and the YZR500 being tied with the MotoGP license, which were in hands of Namco at the time of Tourist Trophy's release.

While they do exist among the car selection files, they don't seem to show up on the selection screens through any method, so the models would have to replace another car file to be seen. The result is the bike's body with the normal wheelbase of the car; meaning that the wheels aren't attached to the bike at all. The models also act like any other car when put in, so they don't balance left or right when turning like how a bike should. The man's body can also be rendered into a car file, but it just glitches out when placed in and loaded.

Bike/Model Video
bike_test0 (yzr500)
pdiver
man

One key interesting thing is that on the side of the bikes, the Tourist Trophy logo is shown. Tourist Trophy was Polyphony Digital's only bike title, released sometime after Gran Turismo 4. This could mean that that game could've been planned or somewhat into development by the time GT Concept came out. An evidence of this is a game configuration file named "tt-e3.gcf", suggesting that Tourist Trophy was planned to be shown at E3 2002 and based on the GT3 engine; the final version of Tourist Trophy was based on GT4.

Regional Differences

In terms of regional differences, there were three versions of the game released (not including manufacturer-specific editions). Each one adds something new (mostly cars) to the previous one, making the game have more variety and content.

2001 Tokyo

The first version of the game that was released in Japan only. This version only features the Tokyo Motor Show 2001 concept cars, like the Nissan GT-R Concept and Toyota pod.

This version also features the Mazda Atenza LM Edition, which is a touring car not seen in the other two versions of the game. Instead, the Tokyo-Geneva version uses the Mazda 6 Touring Car, which is basically the same car, just with a different name (as it was only called the Atenza in Japan, and the Mazda6 elsewhere) and significantly different look, with the version in 2001 Tokyo available in various colors and thus car numbers. Gran Turismo Concept 2001 Tokyo includes also some other cars unused in Tokyo-Geneva. These are Asian spec cars like the Toyota Altezza Gita AS300, Nissan Fairlady Z and Honda Fit W, replaced by European counterparts in Tokyo-Geneva. The bonus items also includes a "GT3 Demo", a video demo of the game at Tokyo R246.

The GT3.VOL for this version was compiled on December 9, 2001.

2002 Tokyo-Seoul

The second version was released in South Korea, in which the game was also used to celebrate the PlayStation 2's official launch in the country. This one features cars from the 2001 Tokyo version plus additional models unveiled at the Seoul Motor Show. It also introduced Hyundai to the series. Tokyo-Seoul features Hyundai models unique to this release: the Tuscani (Coupe in other releases) and the Verna Rally Car (renamed Accent Rally Car in other releases). The "GT3 Demo" bonus item is replaced with 2001 Tokyo intro video, as this build includes a new opening movie.

The GT3.VOL for this version was compiled on March 23, 2002.

2002 Tokyo-Geneva

The third and final version, released in Europe. It features all the cars from the previous two versions plus new models unveiled at the Geneva Motor Show, like the Ford GT Concept (then named the Ford GT40), SL55 AMG, and Abt Audi TT-R; this version was compiled on June 20, 2002. There was also a Chinese/English NTSC version that was released in Southeast Asia, which added 30 cars to the original 2001 Tokyo version; the Asian version's VOL was compiled on June 26, 2002 and is distributed on a dual-layer disc, being the only release to be so.

This version has a screwup where the description for the Mitsubishi CZ-3 Tarmac spills into the description of the Honda NSX-R LM Prototype instead, leaving its car description actually unused in the intended car. In addition, Course Licenses have the cars changed and some cars, such as the Honda Fit/Jazz and S2000 as well as the Toyota Vitz/Yaris were regionalized (including the Opel/Vauxhall language switch).

Special Editions

All special editions of the game contains the whole complete game, but with game configuration (.gcf) files configured to set what content is accessible. However, each demo has a different GT3.VOL compile date.

350Z Edition

A separate version of the game was actually released in North America. This one is exactly as the versions shown above, but with one big exception: only the Nissan 350Z Concept is available as a car choice, with players driving the car for one lap around Cote d'Azur (with all billboards replaced with Nissan logos) with a time limit of 150 seconds. As such, this is considered to be the 'stripped-down' version of the game, even leaving the original opening with the Nissan GT-R Concept (still a Nissan model, appropriately enough, although names of non-Nissan cars still appear in both the opening and the menus) in. (Despite this, the game's code and data files are actually based on the 2002 Tokyo-Geneva version.) However, this version was actually part of a press kit, also featuring 2 CDs, a music CD, and a DVD showcasing the 350Z, so it's not like anyone who had this didn't get most of their monies' worth. A PAL version of the 350Z Edition is also known to exist.

Due to how GT Concept games are structured, it is theoretically possible to create an American version of the game by altering game configuration files, as all cars from the 2002 Tokyo-Geneva version are stored in the game (the configuration file for the 350Z demos is called concept-350z.gcf), although the 350Z demo is compiled earlier on May 1, 2002 according to date of GT3.VOL file (Tokyo-Geneva was compiled on June 20/26, 2002).

Copen Edition

This 'special edition' was released in Japan, given to those who leased the Daihatsu Copen in June or July 2002. Looking at the title screen, it's based off the original 2001 Tokyo version. Players drive a Daihatsu Copen for a lap around Autumn Ring. The introduction movie was not used in this version.

The configuration file for this demo is concept-daihatsu.gcf; the VOL file was compiled on March 26, 2002, with Tokyo-Seoul compiled three days earlier.

Airtrek Edition

Released in Japan, this edition features the Mitsubishi Airtrek, available to drive in a time-limited race with a selection of two tracks: Autumn Ring and Swiss Alps. Unlike the Copen and 350Z demos, this one doesn't force a one-lap race regardless of the difficulty chosen (Example: Choosing Ace, brings a 5 lap race, like the final version), making any race impossible to finish in both tracks due to the strict, 90-seconds time limit. Like the Copen Demo, it doesn't feature any introduction movie.

The configuration file that makes this edition possible is called concept-airtreck.gcf (note the misspelling) and the GT3.VOL for this build was compiled on May 16, 2002, 15 days after the 350Z demo.
