There has been a lot of chatter floating around the community lately about a massive "Horizon Decades" leak for Forza Horizon 6. Let’s clear that up right out of the gate: it’s not a leak. It is a fully official, newly launched four-week Festival Playlist series that just went live on June 18, 2026.
Serving as Series 2 of the game’s live-service lifecycle, Horizon Decades is structured as a chronological journey straight through automotive history. As we cruise through the game’s gorgeous, highly detailed representation of Japan, this event introduces some seriously unique cars, cool new social features, and a much-needed structural shift designed to combat player burnout and FOMO (Fear of Missing Out).
Chronological Eras and Reward Cars
The core gimmick of Horizon Decades is that the playlist transitions through distinct automotive eras every single week, kicking off with the neon-soaked 1980s during the Summer season. Over the course of the month, players can unlock ten targeted reward vehicles alongside brand-new player profile badges.
The car lineup is a stellar mix of absolute legends, returning fan-favorites, and paid Car Pass arrivals.

Social Hubs and Timed Challenges
Because this game leans so heavily into Japanese car culture, the developers are using this series to drop players into some fantastic new social spaces. The biggest addition is the temporary Evolving World Car Meet hub, stationed over at the Hokubu Time Attack Circuit. It acts as a massive, organic meeting ground where you can park, show off your custom liveries, chat with other drivers, and easily organize driving convoys before heading out onto the touge.
The playlist challenges themselves are deeply tied to the historical theme. For example, the opening week features a "Blast from the Past" challenge that requires you to hop into a 1982 DeLorean DMC-12 and hit exactly 88 mph—a brilliant nod to pop culture.
Additionally, Series 2 marks the permanent return of The Trial. This high-stakes event is locked strictly behind endgame progression, meaning only top-tier "Horizon Legends" who have earned their Gold Wristbands can enter.
The Death of FOMO?
Beyond the cars and the map updates, the biggest talking point in the community right now is how Playground Games is structurally changing the live-service grind.
Horizon Decades marks a deliberate mechanical shift away from the aggressive "Fear of Missing Out" tactics that plague modern racing games. The developers are using this series to experiment with giving players explicit, clearer opportunities to re-obtain rare vehicles down the line, actively reducing artificial scarcity.
The goal is to keep the game healthy and accessible for casual players who can't log in every single week. Of course, the community is already a bit split on this—some veterans feel that lowering the scarcity reduces the incentive to grind the weekly playlists, while others are just happy they can take a vacation without missing out on their favorite cars.
Whether you're here to grind out the TVR Speed 12, hang out at the Hokubu car meet, or just enjoy the retro vibes, Horizon Decades feels like a massive step in the right direction for the franchise.
