Forza Horizon 6 Horizon Decades Festival summer season guide: 1980s cars and the Evolving World Car Meet

Forza Horizon 6's summer season in the Horizon Decades Festival Playlist series asks players to do two things: track down 1980s cars and visit the Evolving World Car Meet in the Hokubu area. Both feed directly into seasonal challenges required to progress through the playlist.

Finding the right decade-specific cars is easier than it sounds — the Autoshow and your garage both let you sort vehicles by manufacture year, which cuts through the guesswork fast. The Evolving World Car Meet works like any standard car meet, letting you park and show off your rides, but it doubles as a challenge location tied to multiple Horizon Decades Festival Playlist objectives, including the Sweet Car O' Mine daily challenge.

Both guides were published on June 18, 2026, suggesting the summer season is already live and players are actively working through the new playlist requirements.
