Forza Horizon 6 will reportedly eat up an enormous chunk of your SSD

Forza Horizon 6 is shaping up to be the biggest racing game this year. It's set in a sprawling, fictionalized Japan - with Tokyo described as five times larger than any urban area in previous Horizon titles. The game has already claimed the top spot as Steam's most-wishlisted title for May. Now, a leaked Xbox Store listing shared by @ForzaLeakz on X has revealed another headline figure: this game is enormous.

According to the leak, Forza Horizon 6 weighs in at 144.84 gigs on Xbox Series X|S and 156.65 GB on PC - and that's before a single update or DLC drops. Put that in context against the series' own history. Forza Horizon 5 launched at 103 GB on PC (the game itself requires way more storage space than that) and next-gen Xbox consoles. Forza Horizon 4 came in at around 63 GB on Xbox (at launch). That's a near doubling of install size between FH4 and FH5, and FH6 is pushing another 50% beyond that - before post-launch updates bloat it even more. FH5 reportedly crept past 170 GB with all its DLC installed. 

Still, FH6 isn't even close to the most egregious offenders in the industry. Call of Duty: Modern Warfare III, between its campaign, Warzone maps, and HD packs, can consume over a whopping 300 GB of storage. Final Fantasy VII Rebirth stands at around 145.7 GB, which puts it neck-and-neck with FH6's figure, if true.

The difference with FH6 is that the size kind of makes sense. The game features changing seasons with more variation than seen in Mexico, alongside field recordings captured across all four seasons in Japan. On PC, the game supports enhanced ray tracing, global illumination, uncapped frame rates, and upscaling via Nvidia DLSS 4, AMD FSR 3, and XeSS 2.1. That's a lot of fidelity to pack in. Plus, there are over 550 cars as well.

Forza Horizon 6 launches May 19, 2026 on Xbox Series X|S and PC, with PS5 (curr. $598 on Amazon) to follow later in the year.
