The official release date of Forza Horizon 4 is still a few months away, but some lucky gamers may have gotten a peek at some parts of the game early. Noted by Eurogamer, the upcoming game apparently was being pre-loaded to the Microsoft Store on Windows 10 for some users who pre-ordered the Ultimate Edition.
Of course, the game was unplayable, but an eagle-eyed Forza Fan was able to dig into the downloaded files and an extract a full list of the cars which are in Forza Horizon 4. You can see the full list here on Reddit, but don't be too surprised, as there wasn't anything else the Reddit user was able to do with the files.
Today, some of you noticed Forza Horizon 4 game files preloading on your PCs. This was not intended and you don’t have to do anything. The final game will download automatically when it is released. If you’d like, you can safely uninstall the downloaded files.

The Forza team admitted this weekend that the files were pre-loaded by accident, and was "not intended." They added that you can safely uninstall the files, and reminded users that the full game will automatically download when the game is released.
