GP4: 2026 F1 release: Alpine, Aston Martin and Cadillac

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.

I’ve also begun work on the 2026 helmet set, and you may already spot Sergio Pérez’s helmet in the Cadillac as an early preview of what’s to come.

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.

Happy racing!

GP4: F1 2024 mod v1.7 Christmas update - 2024 cars by fongu

I've got a special release this Christmas, and it comes in the form of the 2024 F1 mod update. 

I know, the last update was only yesterday and it seemed pretty complete, and it is. But this is Christmas, and I'm in a generous mood!

At the beginning of the season, I released the Red Bull RB20, but I've only released a handful of other 2024 cars since then, the McLaren and then the Sauber. 

For this festive season, I want to share with you every car I've made for 2024... and that is every car on the 2024 grid, with a heap of special liveries and track specific logo updates. I couldn't have done it alone, my thanks to GM25, Excalibur (Ferrari) and Paulo Derpich (updates to McLaren and Red Bull) for helping along in this process. 

I'm very appreciative of all the GP4 authors, and in no way do I want to replace any of the existing works already in the mod. But you can run none of my cars, you can run only my cars, or you can mix and match; this mod enables you to select each car author in the CSM menu, giving you hundreds of variations you can try, much like in my 2011 mod. 

Here's a quick preview of what you will get in this update:

Alpine A524

2024 Alpine A524 by fongu for GP4

Alpine ran a number of liveries over the course of the season, tweaking it as the season progressed. The team ran either the pink variant or the blue variant for most Grand Prix. At the final three races of the season, Alpine went 'all pink' with a plain livery. The team also ran two special liveries at the Belgian GP and the USA GP. Both were promotions for the Deadpool vs Wolverine film and the Indiana Jones game. As the livery and logo placements were tweaked through the year, I've attempted to create as many variants as I can. 

Aston Martin AMR24

2024 Aston Martin AMR24 by fongu for GP4

Aston Martin largely ran the same livery and sponsor combinations for most the season, with different partners being featured on the halo at each race (I've not captured all of these minor changes). The team ran additional Aramco colours on their wings at the USA GP, and the last couple of races saw the team run a white rollover hoop. 

2024 Ferrari SF24

2024 Ferrari SF24 by fongu & Excalibur for GP4

Ferrari reintroduced yellow into the main livery to match the endurance racing team, which was a really nice touch. The team gained HP sponsorship from the Miami GP onwards, with a special 'blue' livery ran at the US race. Both Carlos and Leclerc ran slightly different colour halos and car number outlines. The Peroni logo being replaced by Tifosi or Italia in the Middle East races, a nice reminder when the teams in the 1990s were creative with their non-tobacco sponsorship. The Italian GP saw the team celebrate carbon-fibre, and the driver numbers were made black to reflect it. 

This car was created by Excalibur, it's actually his RSCT template car, and I've simply painted on his template and releasing  it now with his blessing. 

Haas VF-24

2024 Haas VF-24 by fongu for GP4

Haas were one of the teams running minimal livery, the car being almost entirely unpainted carbon fibre. For the race in Austin, the team ran a special eagle inspired livery, whilst at the Las Vegas GP, there were more subtle changes made to the car. The team struck a partnership with Toyota Gazoo Racing towards the later half of the year and those liveries have been created for this mod. 

Mercedes F1 W15 E Performance

2024 Mercedes F1 W15 E Performance by fongu for GP4

The Mercedes have flicked between all silver or all black in recent years, and this year saw them run both. The red from the Ineos branding remains a constant, with the blue from Petronas becoming more prominent as the season progressed. The only proper special livery was at the Singapore GP where the silver and blue parts of the livery swapped to celebrate Petronas.

Red Bull RB20

2024 Red Bull RB20 by fongu for GP4

Whilst the opening rounds suggested the season may be a foregone conclusion, the team struggled to make the car competitive at every race. It meant that planned special liveries were cancelled except for the British GP where they ran a 'red camo' livery. Thanks again goes to Paulo Derpich for creating some of the other race variants. 

Sauber C44

2024 Sauber C44 by fongu for GP4

I already released the Sauber in the previous mod update. In this update, I've made the Stake logos a little larger and closer to real life. I've also created the flaming Las Vegas GP livery. As it was a night race, I've decided to emphasise how bright the green looks on occasion. 

RB VCARB 01

2024 VCARB by fongu for GP4

VCARB returned to the brighter blue as seen on the later Toro Rosso cars before they were briefly known as Alpha Tauri. The team ran three special liveries during the season, the first at the Miami GP known as the 'bubblegum' livery. At the Singapore GP, they celebrated denim, with ripped jeans look and a massive zip, (reminding some of the 1999 BAR). Having done a number of denim helmets in recent years, getting the effect and stitching wasn't too difficult. And at the Las Vegas GP, the team went all 'glitter' with another bright design. At the Saudi Arabian GP, the team honoured the female team-members with their names featured on the side of the car. 

Williams FW46

2024 Williams FW46 by fongu for GP4

The 2024 Williams continued to run a couple of shades of blue, but with an added touch of heritage with the red and white stripes for their main livery. The team featured the Duracell bunny on the rollover hoop at the Monaco GP, whilst for the British GP they ran a massive Union Flag (technically it's only called the Union Jack when it's on the seas) with team member names written on it. After Logan Sargeant was dropped, the team were bold to call up Franco Colapinto as his replacement and that brought a number of South American backers to the car. This lead to the return of the yellow engine cover, a nod to the late 1980's/early 1990s liveries. 

McLaren MCL38

2024 McLaren MCL38 by fongu for GP4

There's nothing new from me on the McLaren in this update, but Paulo Derpich has complated the late season sponsor merry-go-round and the Mastercard logos becoming more and more prominent with every race. Thanks to him for his hard work making sure every race is accurately represented. Thankfully for me, there's no new special liveries since my release of this car, but for completeness, I wanted to show them off again here. Congratulations to the McLaren team for securing the Constructors' Championship for the first time since 1998. 

Phew, that concludes one of my most ambitious projects I've ever taken on for a current F1 season, along with the entire grid of helmets and a selection of special lids already released, I'm glad to share the complete pack with you on this special day, I hope you enjoy racing these cars with their various liveries through the season.

GP4: 2022 Alpine A522 v1.1 by fongu

Thanks to some feedback from some of you guys, I've done a quick update on the blue livery on the Alpine. There were some comments about it being too light, so I've taken that onboard and decided on the same blue colour as the car from the Codemasters F1 game. I had upped the highlights effect on the original car, but I've toned that back down for this livery to the normal amount I would normally use. I've also updated the Plug Power logo to match the mid-late season version on the front fin.

Added 8th November

Fixed the front suspension where one of the Genii logos was missing

Sorry that there's no new screenshots, but the links are the same as before. 

GP4: 2022 Alpine A522 by fongu

I've taken a little break from creating helmets to bring you something I've spent a bit of time working on recently. This is the fourth car I've been able to release for the 2022 season and will be featured in the 2022 mod for GP4.

2022 Alpine A522 by fongu

Yes, here's the Alpine, and by popular demand, it comes along with the all pink livery as seen in the first two races of the season. The standard blue livery has reduced paintwork, as with many other teams, this was done in an effort to save weight. Personally, the launch liveries of both variations were truly terrible, but the iterations that arrived in Bahrain and later raced were much better. 

At the time of writing, Alpine are locked in a battle for 4th in the Constructors Title fight with McLaren, with the French team favourites to secure the position. The team were involved in some controversy when first, in advanced negotiations to secure Alonso to an extended contract, were caught out when he was announced to drive for Aston Martin in 2023. Alpine, in response, then announced that junior driver, Oscar Piastri would drive for them in 2023, only for the driver to announce he would not be doing so. Indeed he would soon be confirmed to drive for McLaren in the following season.

This car is made for GP4 and my thanks goes to Carl_gpgames for once again creating lods for me.

GP4: 2021 Alpine A521 - download

Previously, Hega had painted the 2021 Alpine livery onto the 2020 Renault car by Excalibur.
I then added a couple of race specific liveries last month. 

This was the last 2021 car to receive any shape updates from the rule changes, which changed the floors and diffusers mainly. 

Now, I have replaced the floor, diffuser and the bargeboard areas, and with very minor changes to the textures, I can present to you the full 2021 car.  

This is my final contribution to 2021 in GP4, and I'm quite proud of the final product, as found in the 2021 mod, which has been tremendously put together by Carl_gpgames. 

The highlight of the mods ought to be the cars, and I think the quality has picked up in accuracy and scaling. That's in no small part thanks to Excalibur and Hega and Isaint. 

Then there's the supporting wheels and rims (Hega) and helmets (Jvinu, Jsoria and others), that were further enhanced this season for the first time thanks to Oggo, that allowed us to run team specific rims and driver specific helmet shapes, all that adds to the realism. 

Carl_gpgames has done great work throughout the year to put the mod together (both CSM and non CSM options), some new tracks from prblanco and co, some new tweaks like non-refuelling by prblanco and 32bobo32, new physics from carl_gpgames and prblanco, new pitcrews and marshalls from 32bobo32, collision editor by Oggo and, not to forget rracunis and petrus for their contributions. We also had an update to CSM by Zaz and a developing tool in Wad Controller by Duffer, as well as a yet unexplored area of pitcrew model editing by Oggo. 

I'm just grateful to work with such talent and contribute towards one of the best mods in years for this 20 year old game. 

So to all who have contributed to GP4 in this past year, THANK YOU!

And finally, thank you for downloading and playing, enjoying GP4 and keeping it alive. 

GP4: 5 car liveries and 14 special helmets released

Wow it's been a long season and 22 races later and we've completed the season. Christmas is now around the corner, and I've got lots of goodies for you, all free as usual. Although, if you appreciate the work and you're feeling generous, there is a donate button.There's still more to do, but this is likely the last chance I'll get to do any modding before Christmas. 

Car Liveries

Williams FW43B

Williams FW43B 2021 Saudi Arabian GP livery

Williams FW43B 2021 Saudi Arabian GP livery

First up is the Williams livery from the Turkish GP and the Saudi Arabian GP. They ran the Turkish GP livery for most of the tail end of the season. Sadly, Frank Williams passed away on the week leading up to the inaugural race in Jeddah and all teams ran with Frank Williams tributes, a logo from the original team. The halo also includes a quote from the film Top Gun, a favourite of Frank's. 

I will update the Abu Dhabi livery soon, but until then, enjoy the Saudi Arabian GP livery. 

Alpine Liveries

Alpine Qatar 2021 GP livery

Alpine ran with a green rear end at the Saudi Arabian GP, which was to commemorate 100 races with Castrol as the fuel supplier, formerly known as Renault. This dates back to the 1997 season where Jacques Villeneuve won the title in a Williams powered by Renault at the time. 

This livery is included, as well as the US GP livery where they changed the main logos to Mandiant. 

It also includes the Abu Dhabi livery, where they retained the green, but put the Alpine logo back on it. It also includes 'El Plan' on the rear wing. 

The original work was done by Excalibur and Hega from RSCT, all I've done is amend the livery slightly. 

Special Helmets

I feel like there's a mountain of helmets yet to do, but there's quite a few completed so far. I'm not doing them in any particular order, generally I'm picking off the easier ones first. As always, I'm indebted to Jvinu for the shapes and templates available on his blog. It means these helmets are compatible with ACSPRH helmets in other games. 

Sebastian Vettel

Sebastian Vettel 2021 Mexican GP helmet

Here's Seb's Mexican GP helmet. Because of the nature of the helmet, the majority of this helmet is created from photos rather than painted, it was the only way for me to be happy with how the helmet looked in the end.

Sebastian Vettel 2021 Saudi Arabian GP helmet

In Saudi Arabia, Vettel was promoting his own political message, supporting equal treatment of women, particularly in motorsports. The world map is now reminiscent of a train map, which has glow in the dark sections in. That's not exactly possible in GP4, but I have given them as shiny alpha channels as I could to try and replicate the effect. 

Sebastian Vettel 2021 Abu Dhabi GP helmet

Also included in this pack is the Abu Dhabi helmet, which features various phrases that is close to Vettel's heart.

Valterri Bottas

Valterri Bottas 2021 Brazilian GP helmet

Here is Valterri's coffee inspired helmet, designed once more by his girlfriend. This helmet went through various iterations during its creation, in the end I found most of the source pictures, which I had to carefully place on a sparkly base. I'm quite pleased with the alpha channel and reflections on this helmet too. 

(mirror)

Charles Leclerc

Charles Leclerc 2021 Saudi Arabian GP helmet

Charles ran an amended version of his white helmet in Saudi Arabia, adding several red triangular lines and other subtle changes. 

(mirror)

George Russell

George Russell 2021 Saudi Arabian GP helmet

In addition to the car running tributes to Frank Williams, Russell ran this rather simple yet striking helmet design that looks great with the car.

Daniel Ricciardo

Daniel Ricciardo 2021 Qatar GP helmet

It was almost not worth doing a preview of this helmet, but it's the same as the Qatar GP only with updated logos on the visor strip. Other than that, the helmet is the same. 

Daniel Ricciardo 2021 Abu Dhabi GP helmet

In Abu Dhabi, the shiny helmet became glittery. Quite a lot of the helmet has been re-coloured and the alpha layer is completely different. Both helmets are included in the pack. 
(mirror)

Carlos Sainz

Carlos Sainz Jnr 2021 Abu Dhabi GP Helmet

Carlos began the season with a glittery version of his standard helmet, and he's done the same again at the season finale, except the sparkly bits are on the opposite parts of his helmet to the Bahrain version. Also the base colour of the helmet shines between purple, blue and even yellow in some shots. Out of all the sparkly helmets so far, this one is my personal favourite that I've created so far. 
(mirror)

Lance Stroll

Lance Stroll 2021 Abu Dhabi GP 100th Race helmet

This was Lance Stroll's 100th GP and he ran with an amended helmet livery with a special 100 Races logo added. It's also a glittery helmet with the Maple Leaf and the Wings now a very reflective green. 
(mirror link)

Yuki Tsunoda

Yuki Tsunda 2021 Abu Dhabi GP helmet 'Thank you Honda'

I thought Yuki had finished updating his helmet for the year, but he rocked up at the final race with this helmet, with colours amended to reflect more of the Japanese red and white in tribute to Honda's final race in F1. All of Honda's era's in F1 are marked on the top strip. There's shots of two of his helmets painted side by side, and the grafitti is different on both of them. Anyway, out of all the grafitti designs he's worn all year, I'm happiest with how this one turned out in particular. 
(mirror)

Lewis Hamilton

Lewis Hamilton 2021 Abu Dhabi GP helmet

I quietly released the first iteration of this helmet that Sir Lewis has worn at all the Middle-Eastern rounds, but the season finale saw him wear a sparkly version of it. Generally speaking, it's not gone well with drivers who have worn special helmet designs going into title deciders (Max's lid carried a small thank you to Honda on it, so that doesn't really count), so I guess that trend continues.  

(mirror)

Antonio Giovinazzi

Antonio Giovinazzi 2021 Abu Dhabi GP helmet

In the final race of the popular Italian, Antonio ran a tribute livery for his team-mate, Kimi Raikonnen, who is also leaving the team, in a design inspired by Kimi's 2007 Championship winning helmet. Nice, simple, effective and I certainly think it's Kimi's helmet before remembering it's actually Antonio's lid. 

(mirror)

Kimi Raikkonen

Kimi Raikkonen 2021 Abu Dhabi GP helmet

Kimi ran his first proper special helmet of the year, this one inspired by his first helmet some 20 years ago when he drove for Sauber. The helmet also carries a message of thanks on the rear. 

(mirror)

I hope you enjoy this bumper release edition. Until the next post, I want to wish you all a very happy Christmas.
