These are my images... At least say that you taken from TCRF or GT Wiki
I mean, the user (Dane Bishop on GT Wiki or always Sal_89 on TCRF) @SK star 73
If you think I did some malice or anything like that, all I did was just to show the pictures here in this thread. I didn't know it was your images, I'm really sorry.

Is ok, the next time just ask 😉
I'm just "angry" because I didn't posted these by myself
Is correct to "research" who made the original work, and in Wikis in general is very easy (click on the image, and you should read who uploaded it)
 
Yes, pretty funny haha
And is also a special car, one of these that can't do races!

They can do races but they're a bit weird. Only two cars on track, and I think they need to be identical cars but I'm not certain - I have a faint memory of driving the Caterham or the Nike One against a Zonda.
 
Many "Special" cars can be used in Arcade Mode races, but not in GT Mode ones, where just free run, photo drive and photo travel (IIRC), and yes, only one opponent is present while in Arcade
 
So lately I've been into GT4 again and I'm wondering on what basis the colour of a prize car for any given event is determined. For example, I've been doing the New York 200 Miles Event six times now (B-spec ofc) because I want that Charger in a colour I like, but I keep getting it in different colours I don't like :lol: (Dark Gold Metallic, Medium Green, Tan Metallic, Gold Metellic and Gold twice).

When you enter the colour selection in the dealership, all colours except for the Medium Green are Gold tones and close to another. So maybe there's some kind of connection there? Or are prize car's colours completely random and it was pure coincidence that I got 5 cars with just slightly different Gold tones (and a green one)?
 
It's always been completely random except when they purposefully/mistakenly force a specific color to be won. That has happened in GT3 (pink Vitz/Yaris anyone? It has 2 more colors people never saw without hacking them in because of that, and there's the RX8 Concept in GT4 i believe)

Well, I guess I'll keep grinding then. Thank you.
 
...pink Vitz/Yaris anyone? It has 2 more colors people never saw without hacking them in...

I was under the impression that the pink-only Vitz prize car was only for the FF Challenge, and the other places it can be won (like the Vitz Cup) it comes in any one of the four bonus colours. The pink one is only well-known because it's one of the earliest prizes in the game.
 
I honestly don't know, because i never redid those excruciating races lol. Maybe it's only locked on the first one hah

you can force a variant to be unlocked. in the respective file change the value to the variation number (for example yellow rx8 is variation #1. change it to 2 and you always unlock another color or change it to - and its random)

Thanks for the tip, but I'm in no way into modding or anything. I'm just playing it on PS2 from time to time.
 


GT4 First Preview already had a list of car manufacturers in Arcade Mode. It looks like that, it have some errors though. Maybe someone here wants to check that out?

No cut manufacturers. I didn't check to see if there were any that weren't in the final game other than the obvious ones, as Holland, Australia and Spain are all missing, therefore meaning at the very least, Ford AU, Holden, FPV, Gillet and SEAT are missing.

I also found this video, it was made 4 years ago by the same guy. It shows a lot of other stuff in Arcade Mode. Maybe there was a video which shows beta GT Mode (something else than "beta images" that could be fake), but I need to find it.

Also, in BMW Demo and First Preview there are a lot of leftovers in game code. There are test versions of few tracks (some probably were made only for testing), one license test for Chamonix, however I couldn't find La Sarthe, possibly Tahiti Maze wasn't re-made yet. But sadly, those demos are pretty neat, tracks other than you can see during race and idle replays, are a void or the game crashes while loading them
 
Does anyone know what units does the game game use internally for the torque values?

(Edited, I think I found them for anyone interested)

Photos taken by Polyphony Digital in February 2003. If someone still wonders, why one of the tracks was named 'nursnow' in game files, I have some suspicions.

I've always thought that its shape/difficulty remembered the Ring, so maybe fornthis reason PD called "nursnow" the Chamonix course

It's probably the same situation when in GT3 Store Demo 2 there was still Smokey Mountain South (but in different shape) and after that in Gran Turismo 3 it becomes Swiss Alps. It's funny though file name stayed in GT4 and GTPSP. And license versions still had third checkpoint on "old South road", outside the track
 


When it comes to a research topic, I found this video focused on how Gran Turismo 4 was made. Not only we can see the beta and E3 version from 2003, but also a lot of interesting stuff such as Tsukuba with "Lupo Cup" logo, test drive in old chevrolet Camaro through Citta di Aria (back when GT3 HUD was still present) and also beta versions of tracks like New York, Grand Canyon, Fuji Speedway etc.

In fact, GT Concept Tokyo-Seoul had hidden pre-alpha versions of Suzuka, Tsukuba, Motegi and some photo locations. It turns out, by using .VOL extractor on both versions of Nissan Micra demo made in 2002, I found a list of planned tracks which back then had some unseen test tracks and also: Fisco, assisi, grandcanyon, ss_gion, ss_forum etc. (tracks that were seen in this video, but also in E3 beta and promo materials from 2003). First Micra demo was made in October 2002 and it have this file, sadly track list is the same as Tokyo-Geneva.

It would be great to find those VW Lupo Training Versions or Subaru demo made on GTC engine, maybe those also have some hidden stuff
 
I've checked the secret menu in Tourist Trophy. You appear to be able to select what bikes you own but it's a bit glitch as when you first enter the menu, you own no bikes, even if you actually do (this light just be because I'm entering the menu through the main menu though). It also adds the missing Course Registration menu which strangely shows the maximum player count for most tracks as 6. You also don't need to reenter the code after leaving the menu, unlike GT4.
Bit of a gravedig, on what version this was tested? Someone on TCRF is claiming the code has to be reentered every time on their PAL copy of TT.
 
Just lately I've been doing some research of pre-release GT4 in my spare time, mostly on the Wayback Machine. I have a few images I found there that I would like to share:

What's already been shown at that GT4 presentation during E3 2004, but in a better and higher quality.

Most importantly, I found images of never-before-seen beta menus of Garage/Home and GT Auto:

Note: Interesting how part of it uses the same picture as the one on the cover art of the Gran Turismo Lupo Cup Training Version demo builds (but without the color grading in blue for Version 1 or color grading in red for Version 2).

Note: The BMW 120i '04 here has a license plate, like in the GT4 BMW 1 Series Virtual Drive demo builds.

With the discovery of the 24H Le Mans event-spec 2003 C60 in GTC Lupo Cup Version 2, I've starting to wonder if the red #1 2004 C60 from US GT4 and European Space Agency websites are for a similar event that year.

Problem was, for which year? BMW 1 Series Virtual Drive, the earliest near-final GT4 build, wasn't compiled until June 18, 2004 (Le Mans in 2004 was held on June 9-13, qualifying included) and I am not confident if they used 2004-spec cars for in a such 2005 running of a similar event.

EDIT: Period pre-release ancedote that hinted that a such event may have been run at 2004 Le Mans:
I've just got back from Le Mans, They had the ad boards on the mulsanne and they had a big pitch in the village with 4 or 6 stations.

I tried to get pictures after the race, but they were dismantling the stand, also they had a big double spread advert in the paper I got. with six pictures of the courage and alot of writing in french.

Brilliant weekend, but I won't go into it here, I'll go into the rumble strip and post some pictures aswell. Bath and Bed for me now I'm knackered.

Regarding the special red #1 variant of the PlayStation Pescarolo C60/Judd Race Car '04, I have my own theory-craft regarding all of this.

First of all, the first known near-final GT4 build, is the GT4 E3 2004 demo build (May 11-14, 2004); it could be the GT4P SUBARU Version 2nd Edition demo build that is actually the first ever near-final GT4 build (which I have speculated before that it could have been perhaps compiled on either late-April 2004 after PAL GT4P or in the beginning of May 2004 before E3 2004), but the unknown date of that build is a discussion for another day. Anyways back to E3 2004, it is also where the 2004 PlayStation Pescarolo C60 LMP debuted in a playable fashion; it's worth noting that before E3 2004, it was first shown in eight pre-release screenshots of GT4 that were published on April 28, 2004. In there, the car is shown as the #18, but in the green trim (unlike the final release of GT4 where #18 is actually in the red trim), as well as the driver's helmet being identical to the one used in the beta Pescarolo C60 Peugeot 2003 model from the GTC Lupo Cup Training Version 2 demo build. I have here a picture of this version of the 2004 Pescarolo C60:

Beta_Pescarolo_C60_Judd_LMP_'04.webp


Getting into the meat of all this, I think I know exactly what that mysterious #1 red Pescarolo C60 '04 means. You see, in the game files of final Gran Turismo 4, in addition to the pre-release GT4 builds such as the BMW 1 Series Virtual Drive demos, GT4 (Internal) Event Code build, and GT4 First Preview demo, there seems to be filenames for "lmv" variants of four cars:
  • ford_gt_05_lmv
  • m3_gtr_alms_01_lmv
  • mclaren_f1_gtr_long_97_lmv
  • pescarolo_c60_lmp1_04_lmv
Yup, that definitely took a turn... As you stated tankuroded, there was a hint that such event was indeed run at the 2004 24 Hours of Le Mans, and there definitely is evidence in the game files to suggest that it did in fact exist. I also assume that "lmv" stands for "Le Mans Version" or something like that, which might also mean that the GT4 demo build that was playable at Le Mans 2004 might have been called "Gran Turismo 4 Le Mans Version", or something to that effect. The "lmv" versions of the Ford GT '05, BMW M3 GTR Race Car '01, BMW McLaren F1 GTR Race Car '97, and of course, the PlayStation Pescarolo C60/Judd LMP Race Car '04 definitely existed back then in this GT4 Le Mans 2004 demo build, which definitely existed too, as in the GT4 game files (first seen in the two BMW 1 Series Virtual Drive demo builds), there is also the game config known as "config-lemans.adc". Sadly, the car models of these "lmv" versions are missing in any build where their filenames are featured. However, there are two types of leftovers for them: vehicle banners, as well as, most importantly, thumbnails, which are the only one we can see how they actually looked like. I have the thumbnails down below, sourced from The Spriters Resource (special thanks to the user blueberrymuffin for uploading them in The Spriters Resource):

ford_gt_05_lmv.webp
m3_gtr_alms_01_lmv.webp
mclaren_f1_gtr_long_97_lmv.webp
pescarolo_c60_lmp1_04_lmv-webp.1547955









Surprise surprise, the thumbnail of the LMV version of the 2004 Pescarolo C60 looks identical to the #1 red 2004 Pescarolo C60 that is shared in the post I'm replying to. This basically confirms that the #1 red C60 '04 is definitely the LMV variant!

Although there are sadly no images nor documentations of the LMV variants of both the BMW M3 GTR Race Car '01 and the BMW McLaren F1 GTR Race Car '97 at all whatsoever, there does exist a few pre-release screenshots of GT4 that were published on around October 2004 (if not, late-2004) through Kikizo that featured the LMV version of the Ford GT '05 at El Capitan in some of them. The screenshots can be seen below:

Ford_GT_'05_(Special_Livery_Version).webp

Ford_GT_'05_(Special_Livery_Version)_2.webp


As you can see, the 2005 Ford GT LMV's livery seems to be a red color (possibly Mark IV Red Clearcoat) with decals featuring racing number #1 (same number as the 2004 Pescarolo C60/Judd LMV) on the hood, doors (both sides), and on the left side of the engine cover on the rear. Apparently, the livery alone seems to be heavily inspired by the 2003 Ford GT Concept (with a few tiny differences here and there).

Anyways that is all for my post. In conclusion, there is evidence that a GT4 Le Mans "LMV" 2004 demo build exists, with the cars that were playable on it with their own special liveries, with leftovers of being thumbnails as well as two of the LMV variants actually being seen outside of the thumbnail leftovers. That is all I have to say. Apologies for the extremely long post, and thank you so much for reading. If you have something to say, please don't hesitate to reply!

Oh and here's another beta GT4 screenshot featuring the PlayStation Pescarolo C60/Judd Race Car LMV '04 undergoing a pit stop:
