Today I’m excited to share the latest additions to the 2026 grid: the McLaren MCL40 and the Haas VF-26.
As mentioned previously, this year’s cars have been split between myself, Excalibur, and Isaint—so this release marks my final contribution to the 2026 lineup. Huge thanks to Excalibur for the outstanding work on the new wheels and rims; they really elevate the overall look of the cars. You may also spot an early preview of the 2026 helmets, with a full release to follow once they’re complete.
McLaren MCL40
The McLaren team continue to use the benchmark Mercedes power unit and having not had an ideal start to the season, nevertheless showed a competitive outing at the recent Japanese Grand Prix.
It was a refreshing change to work on something closer to the sharp end of the grid—my earlier allocations seemed firmly rooted at the back!
Haas VF-26
The Toyota backed Haas team have fared well in the midfield, with some reasonably strong showings so far. Nothing spectacular, just good solid progress with capable drivers behind the wheel.
After many years of quite bland and dull liveries, the Gazoo Racing effect has produced once of the better looking liveries on the grid.
As with my previous release, you will find the internal cockpit shape for each car, along with the collision mesh file.
In the background, work has begun in compiling a mod, and when all the cars, helmets and a good set of physics are shared, I will release a CSM and a non-CSM version of the mod. Until then, I hope you enjoy these new additions to the 2026 grid.
The 2026 F1 season is now under way, and so is work on bringing the 2026 grid to Grand Prix 4.
I’m thrilled to be able to partner up with the RSCT team and divide up the work between us. I'm grateful for Excalibur and Isaint, veterans of the GP4 modding scene and the dedication they have to keep preparing and sharing up to date cars with you each season. Indeed, my contribution this year is indebted to partnering and discussing and sharing resources together with them.
Even things like a shared light texture, wheel sizes and positions, and some geometry discussions have all helped to create a consistent, polished release.
And today, I’m excited to reveal not just one car, not two, but three cars from the 2026 grid! The regulations are so tight in some areas that some parts of the car can be reused for each car. However, each team has still explored unique aerodynamic philosophies, giving every car its own character.
Alpine A526
I have for you the Alpine A526. Having ditched their own engine programme, they are now Mercedes customers, and they did well to negotiate a deal with what appears to be the benchmark Power Unit on the 2026 grid so far. The styling and presentation of the team is very similar to 2025.
Aston Martin AMR26
There is also the Aston Martin AMR26. Working on the British marque is always a highlight, though nailing the perfect green in-game is a challenge! This year’s AMR26 is striking, clearly bearing the signature of Adrian Newey’s design philosophy. While the Honda power unit isn’t quite up to scratch yet, at least you can enjoy a reliable car in GP4. Why not crank your force feedback to 400% for a more realistic experience.
Cadillac MAC26
And then I've also worked on the Cadillac MAC26 - a nod to the founder of the project, Mario Andretti and his son, Michael. Sadly, it's another bad episode of a tumultous relationship between Michael and F1, but I am so glad to have the right number of teams on the grid to fit GP4! Its asymmetrical livery might not be to everyone’s taste, but it’s guaranteed to stand out on track.
Please note that the rims and helmets shown here are experimental for now. Excalibur is hard at work on a dedicated 2026 tyre and rim pack, which will bring everything together visually once the full set is ready.
Included in each pack are the car shapes and the textures as seen at the Australian GP. You’ll also find the internal cockpit view for each car, along with the collision mesh file.
Thank you all for your continued support of the GP4 modding community.
I hope you enjoy these new additions to the 2026 grid.
It’s time for a new compilation of the 2004 Track Pack.
Since the original release in 2023, a number of community improvements have emerged — particularly updated liveries and revised layouts based on the F1Virtual versions of several circuits. Rather than leaving those improvements scattered across separate downloads, I’ve consolidated them into a cleaner, updated v2.0 package.
What’s New in v2.0
Magny-Cours
Now includes Josekast’s updated livery set, based on the F1Virtual version of the circuit..
Spa-Francorchamps
Updated to the correct layout, incorporating work by MarioB, btone and others. This version better reflects the configuration used during the 2004 season by Josekast.
Hockenheim
Revised with Josekast’s livery updates, again based on the F1Virtual release, bringing improved sponsor placement and trackside detail.
Sakhir (Bahrain)
Now uses the newer version of the circuit by F1Virtual, replacing the previous version that updated the old layout.
Shanghai
Updated version by Naitch7, based on the F1Virtual release.
Additional Inclusion
I’ve also included the 2006 Suzuka by KTC. It is not selected by default within the trackpack, but it’s available as an option.
This version features the altered final chicane layout, which more closely reflects the later configuration of the circuit. It is slightly buggy in places, but I felt it was worth including for those who prefer the revised chicane geometry over the older version.
I hope you enjoy this little update to the 2004 season from the best currently available community updates.
V2.1 includes a fixed version of Indianapolis - by Ricardo Lampert and hi-res textures by Caelen.

2004 Trackpack v2.1 (for TSM)
This release is set up to be used with TSM - just extract the files into your Grand Prix 4/Tracks directory.
I’m very grateful to Theofilos for starting the Real Helmets Project for Assetto Corsa last year. It’s an incredibly detailed and well-researched helmet project, and it immediately stood out for its accuracy and modelling quality.
With his permission, both myself and Nick9320 (who now primarily mods for rFactor 2) were able to convert the work to our respective games, helping bring a consistent, high-quality helmet standard across multiple sims.
So far, the project includes:
The Arai GP7
The Bell HP77
Both helmets come with various clear and solid wing variants. The Bell HP77 also includes the alternative wing specification used by the Ferrari drivers, again available in both clear and solid versions.
In addition, the Bell features multiple visor options:
Standard short visor strip
Extended visor strip variant
These small details make a big difference when recreating specific drivers and seasons accurately.
I’ll admit this release took a little longer than planned. Part of that was waiting to see whether Theofilos would be adding the Stilo and Schuberth helmets to the project. In the end, he shifted focus toward improving the driver body model in collaboration with the VRC modding team instead.
Today, I’m releasing the converted helmets for GP4 (kindly converted by Excalibur), along with the original templates provided by Theofilos.
The key benefit of this approach is compatibility. Helmets created using these templates will now work consistently across all three supported sims. That opens the door to shared designs, easier collaboration, and a unified standard moving forward.
Personally, I’m really pleased to have these available. They’re noticeably more detailed and more accurate than the previous generation of helmets, and they raise the visual standard of modern-era mods considerably.
Huge thanks again to Theofilos for the original project — and to everyone involved in bringing it across to other platforms.
*** These helmets are based on the original RHP release. I am trying to gain permission to release the updated VRC version. ***
A small but welcome update to the F1 2011 mod — and this one comes courtesy of KerleyF1.
This release focuses on the subtle presentation in the CSM menu interface.
Some of the menu preview images within CSM were either missing or not displaying correctly. While this didn’t affect on-track performance or gameplay, it did leave parts of the menu feeling slightly incomplete, particularly on the Young Drivers Test variant.
KerleyF1 has now resolved that.
All missing preview images in the CSM menu have been created and are displaying correctly, ensuring:
Full visual consistency across all car/team selections
Proper thumbnail previews where previously blank
A cleaner, more polished mod-loading experience
It’s a purely cosmetic update, but these finishing touches help maintain the overall quality standard of the mod, probably the biggest single season mod available in GP4.
Big thanks to KerleyF1 for taking the time to tidy this up.
You can download the updated files here.
Installation Notes
Fongu's 2011 v1.3 CSM Mod
This update is a patch on the original mod, if you haven't done so already, install the mod first.
If you’ve downloaded the B197 recently, you’ll know it already features David Marques’ excellent mapping and 4K textures as part of the original release.
While he was preparing the F1 Challenge release (available here), David noticed a detail that deserved a slight correction.
Specifically, the yellow section at the rear of the B197 — an important mark of the colours of Benetton livery — wasn’t matching its real-world reference as closely as it could. Even subtle variations in tone can be noticeable when compared to period photography or in-game lighting, so David made a quick adjustment which looks a lot better.
All texture files have now been updated to incorporate this change for all races.
