GP4: ICYMI - January 2026

A new year is under way, and it's time again to catch up with the rest of the 2025 releases in the Grand Prix 4 community. It's been a busy final few months of the year and there's plenty of cool developments by new and familiar authors who have shared their work with the community.

On my side, I have now updated this blog with mirror links to most of these downloads and some on the dedicated 2025 Download Resources page.

Without further ado, let's take a look at what's been released in the community lately.

New Features

GP4++

by Öggo

This combines the Individual Meshes & Textures with the hi-res pitcrews DLL, whilst adding a new feature to have driver specific engineers, and individual meshes for engineers and pitcrews. There are other features now editable directly, such as the NoCD option, enabling advanced car-shader for internal steering wheels, and cockpit visor customisations.

Hi-Res Pitcrew Meshes

by Öggo

Hi resolution pitcrew meshes has been available for a while now, but now Öggo has created a working model for engineers and pitcrews. It is a proof of concept, but still a massive improvement on the original mesh from the original game. This comes with a PSD template, so I look forward to seeing some new skins painted soon.

A new tool that is still under development by Kresljedos for calculating standings for a full F1 season, due to GP4's limitation of only a 17 track season. This runs in a browser.

SkaningeN's add on Packs

2012 Cars Add-on (Season Pack)

by SkaningeN

He writes:

"So 2012 it is. And it's quite similar to the 2011 Add-on, but this time I decided to bring you an whole season set of cars in one package. Even the versions I have not edited so you can easily make your own mod if these are the cars you want to use. All versions (I Think) is included in this pack, I've done my best to spot differences, correcting mistakes on existing ones and adding missing versions. Most cars are converted from F1CM by Josekast, with a select few from Soulbringer, Hega and RSCT."

2012 Helmetset and Shapes

by SkaningeN

He writes:

"The 2012 helmetset now with seperate helmet shapes. This helmetset have gotten some tweaks and now also gotten the correct helmetshapes for all drivers. I've added some missing helmets, fixed some others, fixed the alphalayer on some and added new versions that seemed to be missing.

All helmets from the 2012 season (that I know of) is included in this pack and are painted to fit the correct helmetshape. And I've done the best I can to make sure each helmet has the correct visor tint for the right races. But in most cases, you can decide yourself. You can run all helmets with individual shapes or you can use all helmets with only one shape for all. But if you only use one shape, some textures will not fit properly, most cases the visor tear offs and the new visorstrips on the updated shapes."

2012 Tyres & Rims

by SkaningeN

He writes:

"Here is a 2012 tyreset that has it's roots the fantastic years of 2005 to 2009. With Enzojz and Lee's great talent for modding GP4 back then, I've just modernized their work a bit to bring you an updated 2012 tyreset."

GP4: ICYMI - Summer 2025

It's been a little while since I have posted on my blog. Inactivity on the blog does not mean that I am not busy working on projects, but mods takes time and dedication and sometimes real life has to take precedence.  

You may have noticed, this site has been going through a bit of a rebrand, hopefully to make things easier to see and find. This is not least because there's close to 100GB of downloads now available on this blog.

However, that has not stopped the community from being busy and sharing their works. 

There's been a flurry of activity on the 2025 cars, and Excalibur and Isaint have been doing a great job in bringing the entire grid to Grand Prix 4.

GP4: 2011 Mod V1.2

 

The 2011 mod is one of the most content heavy mods I've ever released, and somehow there's so much that has been added for this update. 

This update largely includes the new updates created by SkaningeN, who has painstakingly gone through each GP and updated as much of the cars, helmets and tyres and wheel rims as he could. His remarkable eye for detail and patience to make all the changes is really awe-inspiring. 

On the cars side, most of his updates are on Josekast's cars. I've tried to make sure it doesn't 'break' the other cars don't have similar track specific attention. 

This is with the exception of the Ferrari, where he has updated my version, where a few additional shapes and textures have been added. 

I have amended the mapping of Jucksman's version of the Sauber so that it could share the track specific liveries that also work with Josekast's version. 

For the McLaren, the track specific shapes are Josekast's cars, but the track specific textures are against Jucksman's set. Sorry to split the two up, but I am restricted by the structure of the mod. I wanted to release this as an update to the existing mod, rather than having you install the whole mod again. 

Thanks to Kyle24427, who has kindly converted SkaningeN's 2D tyre rim updates to work with the 3D rims in this mod. I've adapted his implementation to save space and still get the same effect. I've decided to stick with the original intermediate and wet treads, where I also fixed the wet tread texture that did not have any blurring. This was largely motivated by not updating the tyre shapes for each team.

On the helmet side, I have installed all the updates, and I've updated the drivers Schuberth helmet shapes with the amended angle. I've also corrected Button's helmet to use Arai instead of Bell. 

I've included the Individual Meshes & Textures dll tweak by Öggo, but unlike my other recently released mods (where it is essential to the running of the mod), here I've only really used it here for the 3D rims tyre mirroring bug, it does little else in this mod. 

I've also added to the patch the helmet visor tweak that removes the green and orange visor tints. 

This mod also includes the high resolution menu fonts, thanks again to Öggo and Carl_gpgames for that. 

There's also some additional fixes. 

• de la Rosa's helmet now loads correctly in Montreal. 
• the soundsets were not loading correctly, this is now resolved, and I've added an option to not run any. 
• I've fixed the cockpit clipping issue if you have the cockpit view fully zoomed out. 
• Also fixed is in the CSM menu where Jerome D'Ambrosio has the wrong flag loading for him. 

Installation Notes

Fongu's 2011 v1.2 CSM Mod

This update is a patch on the original mod, if you haven't done so already, install the mod first.

GP4: ICYMI October 2024

It's been a little while since I last updated you with news from the GP4 community, but we've had some ground-breaking releases that will shape the way in which GP4 will be modded and updates shared in the future. 

Once again, legends from the GP4 modding community have cooked up an amazing new tool that opens up a new world of possibilities to modding GP4. We also have a host of other exciting new updates below.

Part of the problem beforehand was that a lot of patches were editing the code in GP4.exe itself, which was limited. GPxPatch and GP4 Tweaker opened up new ways of changing GP4 by use of external DLL's. This tool, which is compatible with both GPxPatch and GP4 Tweaker, uses that same philosphy and started creating a big library of existing and new tweaks to be added to the game without having to touch the GP4.exe file. There's great compatibility with previous tools and, for the creative, opens up the possibility of previously thought impossible (see below).  This is a real game changer, and has been developed over many months, bringing together some of the brightest minds in GP4 modding all together in this new tool. It will take time to learn how to make the most of this new tool, but it will be well worth your time and energy.

Öggo's Dev Corner
In conjunction with the release of GP4 Memory Access, we have some amazing new possibilities now possible by Öggo.  High resolution pitcrew models - previously it was limited to only 400 vertices, but now it is no longer limited. With pitcrew models able to be edited in Blender, this is a significant addition.  Individual Meshes & Textures DLL - This DLL expands original Grand Prix 4 to allow full control of how meshes (front/rear wheels, helmets, cockpits, cars) and textures (cockpits, helmets) are loaded, supporting per-driver, per-team, and per-track custom loading. It includes features to manage LODs (Level of Detail), auto-naming conventions, and fallbacks to default GP4 assets when custom assets are unavailable. This DLL enables, for the first time ever, the possibility of having individual cockpits, as this was not possible in native GP4.

2001 Melbourne Track
Hega is doing an amazing job with the 2001 tracks, utilising the AI upscaled tracks by carl_gpgames and his own high resolution textures and objects. We now have this beautiful Australian track added, with 11 out of the 17 tracks now updated.

SkaningeN's 2010 cars add-on
SkaningeN is back with his track specific car updates, to go with his previous releases of tyres & rims and helmet packs. The cars are originally by Soulbringer and also CM and Josekast respectively. This is a massive work and worth your time to check out all the versions with a season run through.

1997 Track Pack Hi-res Update
After the successful release of the 1996 track pack, we have an update to Plodekk and Cleberpister's 1997 track pack, with new pit garages, pit stands and other updates, as well as new performance files and physics.

GP4: ICYMI August 2024

Wow, it's nearly the end of August already and it's time to catch up with updates to this blog and updates from the GP4 community. 

New Car Templates page

I've added a new section to my blog, car templates. To be honest, I was never one to collect templates, so you will have to help me out if you want this page to fill up. In recent years, Excalibur and the RSCT crew have been providing us with great generic F1 cars. Somebody asked me for a template for the 2021 Williams for a GP4 league and I've shared that here too. Raulongo also shared templates for the 2008 cars we did together. 

2001 Lola CART template by Öggo and Adry77

However, I'm quite excited to find some golden oldies by Öggo and Adry77 in the 1999 Reynard CART car and the 2001 Lola CART car. 

I've also found in my archives, templates for a still-born IRL project from 2006, with two templates for the Dallara and the Panoz, plus completed car and textures of the Penske. 

There's also the 2013 Dallara GP3/13, but I'm hard pressed to find anyone doing any liveries for it. 

And there's the Gen 3 Formula E car pack I released late last year. 

Click on the yellow banner below to explore the new Template page. 

GP2 (as in the old F2) content added

Thanks to thestig88 for sharing this pack (https://www.grandprixgames.org) and looking through my own archives, I've been able to add some GP2 content. There was a 2008 GP2 Asia series created by Damon and released as a non CSM set. In this release, it's been added to the 2008 GP2 mod by Lee, and so both mods are included together in this download. 

I've also added to this blog 2006 GP2 liveries, which I think are by Drex, but I'm not sure. 

And finally, I've added a 2010 GP2 non-CSM mod. Again, I'm not too sure where this is from, but its likely to have originated from the GP4 Spain forum, with Damon possibly involved again. If you have any information for me, let me know and I can update this blog. 

I hope you enjoy some of these mods from the archives. 

Recent releases

1968 Hockenheim, Germany track updated
The Viking75 news trail continues with this update to 1968 Hockenheim, originally updated by drt01 and atticus. This track really does have a great vintage feel, as you blast down the straights in the Eifel forest before it was punctuated with chicanes and 'mickey-mouse' sections in later years.

1958 Ain Diab, Morocco track dat file
Thanks to Viking75 for this basic beta of the Ain Diab track, the venue for the 1958 Moroccan GP. We don't have many early F1 tracks in GP4, so this is most welcome and I really do hope it gets some nice scenery to match in the not too distant future.
