A Forza fan on PC who preordered the Ultimate Edition of Forza Horizon 4, yesterday discovered the game downloading through the Windows Store early. Examining the game files, they discovered a roster of more than 450 cars.

It’s important to note that this may not (and considering DLC, probably is not) the full vehicle lineup for Playground Games’ open-world racer, just announced at E3 2018. The game is still more than three months from launch and vehicles could be added in or held back. (The lineup changed between a similar leak and the launch of Forza Horizon 3 in September 2016). The original poster said there are some manufacturers who will appear that aren’t in this list, for example.

Another redditor on the r/forza subreddit, working from the filenames, posted a full list of what was found, organized by manufacturer.

Reaction from the Forza community, aside from picking over why certain cars aren’t featured (or returning from a past edition) seems to center on a fear that any new cars will be premium DLC. There’s also some disappointment at Toyota’s continued lack of representation: just three vehicles, all of them trucks. (Last year, Forza’s community manager confirmed that Turn 10 and Toyota couldn’t come to an agreement on Toyota production cars for Forza 7; this is probably a continuation of that).

We’ve reached out to a Microsoft representative to ask what happened with the early download and how that’s been addressed, as well as any new guidance on how this may affect their fleet rollout messaging. For now, 450 cars is a lot, even if that’s an incomplete list.

Update: The official Forza Motorsport Twitter account had this to say last night:
