The excitement surrounding Forza Horizon 6 continues to grow as players search every corner of the game for clues about future content. Alongside the latest updates, dataminers and dedicated community members have uncovered evidence pointing toward more than 20 potential vehicles that may arrive in upcoming expansions. While nothing is officially confirmed until the developers make an announcement, these discoveries have generated enormous discussion across Reddit, forums, and social media. For players already collecting rare vehicles and earning Forza Horizon 6 Credits, these leaks offer an exciting glimpse at what the game's garage could look like in the months ahead.

Before diving into the list, it's important to understand how game leaks actually work. Discovering a vehicle inside the game files does not automatically mean it will become playable. Developers frequently include unfinished assets, physics models, textures, or audio long before a vehicle is released. In some cases, cars remain hidden indefinitely due to licensing negotiations, production schedules, or design decisions.

A perfect example is Bugatti. Several Bugatti physics files reportedly exist within Horizon 6, yet the manufacturer is still absent from the playable roster. This suggests that technical implementation is only one part of the process. Legal agreements with manufacturers and third-party licensing partners are equally important before a vehicle can officially join the game.

Evidence Found in Forza Motorsport Files

One of the strongest sources of these leaks comes from Forza Motorsport. The title contains more than 700 vehicles, but not every asset is currently obtainable by players. Hidden throughout the files are unused thumbnails, textures, manufacturer badges, and vehicle data that have historically been used as preparation for future releases.

Dataminers discovered numerous manufacturer logos stored inside media folders and MFR directories. After converting these assets into readable DDS and PNG formats, they identified several badges representing vehicles that have yet to appear in Horizon 6.

Although these files alone cannot guarantee future additions, previous updates have shown that many cars first appeared in hidden Motorsport assets before eventually arriving in Horizon titles.

Japanese Cars Lead the Way

Considering that Forza Horizon 6 is set in Japan, it's no surprise that Japanese manufacturers dominate the leaked list.

One of the most interesting discoveries is the 2023 Toyota Prius Prime. While not traditionally viewed as a performance vehicle, modern hybrid cars have become increasingly popular among automotive enthusiasts, and Horizon has always embraced diversity within its vehicle lineup.

Another notable finding is a different version of the Toyota Starlet Glanza V, specifically the 1998 Excellent Package. Since a standard Glanza already exists, this could represent another collectible variant with unique tuning options.

The mysterious Subaru Wilderness badge has also sparked plenty of speculation. Although no specific model has been confirmed, many players believe it could refer to one of Subaru's newer off-road crossovers, offering fresh rally possibilities.

Fans of classic Japanese performance cars were excited to see the 1993 Nissan NX 2000, a lightweight coupe with strong customization potential. Another welcome addition would be the 1998 Mitsubishi Pajero iO, a compact SUV that could become a fun off-road competitor.

One of the most unusual discoveries is the 1967 Mazda Luce RX-87 Rotary Coupe Concept, a rare rotary-powered concept vehicle that would fit perfectly into Horizon's collection of historic automobiles.

New Manufacturers Could Debut

Several leaks hint that Horizon 6 may introduce manufacturers never before featured in the franchise.

The 2022 Ineos Grenadier stands out immediately. As a rugged off-road SUV inspired by classic utility vehicles, it would provide players with another capable option for exploration and rally events.

Another unexpected appearance is a possible GAC vehicle, potentially the Trumpchi GA6. If accurate, this would significantly expand the diversity of manufacturers represented in the game.

Meanwhile, the classic 1990 Fiat Panda 4x4 has also been spotted. Fiat currently has very limited representation in Horizon 6, making this charming little off-roader an exciting possibility for fans of compact adventure vehicles.

Muscle Cars and Modern SUVs

American performance fans also have reasons to be excited.

Among the leaked vehicles is the 2023 Dodge Challenger SRT Demon 170, arguably one of the most powerful production muscle cars ever built. Since Horizon 6 already includes several Dodge models, adding the newest Demon would be a natural progression.

BMW enthusiasts may receive multiple additions as well. While the previously leaked BMW X6 M Competition has already appeared in Horizon 6—helping validate the accuracy of earlier discoveries—three additional SUVs remain unconfirmed:

• 2025 BMW XM
• 2024 BMW X4 M Competition
• 2022 BMW X3 M Competition

These performance SUVs would greatly expand BMW's modern lineup while offering new tuning opportunities for both road and off-road events.

Honda fans may also have something to celebrate with the leaked 2025 Honda Prelude and the nostalgic 1986 Honda Accord Aerodeck, two vehicles representing completely different generations of Honda engineering.

Audio Files Reveal Even More

Vehicle textures aren't the only evidence.

Dataminers also found references inside XML audio files containing engine sounds, announcer dialogue, and event mapping information. These files often indicate that developers have already begun implementing certain vehicles internally.

Among the vehicles referenced are:

• 2018 Alfa Romeo #11 Handy Motorsport Giulietta BTCC
• 2018 Chevrolet #3 Camaro Trans Am
• 1977 Chevrolet #14 DeKon Engineering Monza
• 2018 Mazda #55 Joest RT24P

Because these audio files closely resemble those found in Horizon 5, many players believe Playground Games is reusing existing assets while preparing future content updates.

Promotional Material Supports the Leaks

Some of the strongest evidence actually comes from official promotional material.

The 2019 Formula Drift #64 Chris Forsberg Racing Nissan 370Z appeared during the 2022 Xbox & Bethesda Showcase but has never become available in Horizon 6. Interestingly, the game currently includes a similar 2023 version, suggesting the earlier model may still arrive later.

Another vehicle spotted in previous promotional images is the 1988 Mitsubishi Starion ES-IR A187A. Although never officially announced, repeated appearances in marketing materials make it one of the more believable candidates for a future update.

Looking Ahead

Taken together, the hidden textures, manufacturer badges, audio references, and promotional appearances create one of the strongest collections of evidence the community has seen so far. Even better, several earlier leaks—including the Koenigsegg Gemera and BMW X6 M Competition—have already become reality, lending additional credibility to many remaining entries.

Of course, every leaked vehicle should still be treated as speculation until officially confirmed. Licensing agreements, development priorities, and technical considerations can always change before release. Nevertheless, the current evidence suggests that Forza Horizon 6 still has plenty of surprises waiting for players. Whether you're hoping for iconic Japanese classics, modern SUVs, race cars, or powerful American muscle, the future looks incredibly promising. As more updates arrive, fans will be watching closely to see which of these leaked vehicles finally make their debut while continuing their buy Forza Horizon 6 Credits journey through one of the franchise's most ambitious open-world racing experiences.
