When it comes to PlayStation-exclusive hard drive hogs, Gran Turismo Sport has long been the champion. While the game launched at a relatively svelte 43 GB, it eventually ballooned to over 100 GB (102.5 GB to be exact). So, this raises the question – just how much space are we going to have to clear for the upcoming Gran Turismo 7? Is it going to be another SSD-gobbling beast?

Turns out it is. While there are somewhat conflicting reports, it seems Gran Turismo 7 will take up around as much disc space as a fully-updated Gran Turismo Sport at launch, and it’s likely the game will only get bigger from there. Currently, the PlayStation Direct store lists both the PS4 and PS5 versions of Gran Turismo 7 at 110 GB. Now, these kind of store listings are often ballpark estimates that tend to air on the side of caution, but the usually-reliable PlayStation Game Size Twitter account is reporting the PS5 version will be 89.5 GB before the Day 1 patch, which could very well carry the game up to that 110 GB mark.
