Horizon Backstage in Forza Horizon 4 is a roster of exclusive cars available to be redeemed by players using passes, and was introduced with Update 28 on October 13, 2020. The selection of cars on offer is derived from the winners of weekly community votes.
Players can access the Horizon Backstage by driving to its location behind the Mainstage at the UK Horizon Festival, selecting "Horizon Backstage" under "Autoshow" at the Autoshow or any owned homes, or by selecting "Horizon Backstage" under "Cars" in the pause menu.
Within the Horizon Backstage, players will find a roster of cars they can acquire with passes. Any car listed can be redeemed with a pass but are limited to a single car per player.
Passes are rewarded by completing milestones through the Festival Playlist and a single pass can be used to redeem any car listed backstage.
Players can accumulate multiple passes and are not required to use them as they have no expiration.
