Prius Trial Version

This is a sub-page of Gran Turismo 4 Prologue.

This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: There's probably more unused cars.

This version was released in Japan, possibly at one of the dealerships. Looking at the title screen of this one, you wouldn't think it'd be based off of Prologue and more off the final, as the "Prologue" title is dropped and just displays the normal logo with "PRIUS TRIAL VERSION" on the bottom. However, when you actually press Start, which is labeled as a Prius' power button, you can already start to notice that in fact it is. The menus are similar, it uses the recycled Gran Turismo 3 music in some places, and some of the HUD is kept the same. The difference is you can only race a Prius 1 lap around Tsukuba Circuit, the rest of the HUD that isn't the same has been replaced to show the hybrid aspects of the car, and before the race you watch a quick video of someone turning on the Prius (you know, to convey the realism). Speaking of videos, the trial also has a nice video showcasing the car, with some guy speaking in Japanese probably telling you about its features.

As the game is based on the Japanese version of GT4P, all 3D objects in the game are in GT3 format.

Unused Content#

Remember when YT had a little indifferent face when a video went down? TCRF remembers.

This page or section has one or more broken YouTube links.
Please find an archived version of the video(s) or a suitable replacement.

A fair unused content amount is present in the disc, from courses to car bodies, plus the PRIUS G '02 is drivable if the memory is edited. Major part of the unused content in this demo, is also present in full game. YouTube video

Unused Tracks#

Some of the unused courses are as follow:

test: A void with a skybox and some cones.
test2: Super Speedway as seen in Gran Turismo 3, but set at night.
laguna: An earlier build of Laguna Seca.
nurburgring: A really early build of the Nurburgring, having only the track's road map and some elevation done.
yosemite: The early version of the Cathedral Rocks Trial rally track, having just a basic road layout and some trees put in.
route5r: Similar to the other early build of Special Stage Route 5 seen below, but with a bit more done.
Twin Ring Motegi: In a very unfinished state here and has untextured buildings.

Unused Car Bodies#

Some of the unused car bodies are as follow:

206 Rally Car: Takes place of the Polyphony001, and wow, is it very glitched-up here. It's somewhat surrounded by white 'bands', and has missing or very odd rims.
Lancer Evolution VII Rally Car Prototype: The same prototype car from Gran Turismo 3, but is a bit more updated in this version, including less white on the bumpers and the number 7 displayed on its door.
