The Horizon Decades Festival Playlist in Forza Horizon 6 has rolled into Autumn, and there's a solid stack of challenges to work through before the season flips again. From 1990s car restrictions to a free Lamborghini Diablo GTR up for grabs in The Trial, this week gives you plenty of reasons to keep the engine running.
How do Daily Challenges work in Forza Horizon 6?
Daily Challenges drop one per day throughout the season, but here's the part most players miss: they stay active until the season ends. You don't need to log in every single day. Stack them up, then knock them all out in one session before the deadline hits.

Each completed Daily Challenge pays out 1 Festival Point and 5,000 Credits. Seven challenges across the Autumn season means seven points and 35,000 Credits total if you clear the board.
What is the Weekly Challenge this Autumn season?
The 1991 GMC Syclone is the featured car for this week's Weekly Challenge. You need to own it before you can start, and the steps must be completed in order. Finish all four and you walk away with 5 Festival Points and 25,000 Credits.
Don't have the Syclone yet? You can earn it by winning the On The Trail Seasonal Championship (details in the events table below), so that's actually a natural entry point if you're starting from scratch.
The four steps in order:
- Own and drive the 1991 GMC Syclone
- Complete 2 runs at the Irokawa Quarter Mile Drag Meet
- Earn 3 Awesome Wreckage Skills
- Win a Street Race

All Horizon Decades Autumn seasonal events and rewards
Beyond the daily and weekly structure, the Autumn playlist loads up with photo challenges, collectibles, Seasonal Championships, Danger Signs, Speed Traps, a Trailblazer, a Seasonal Job, The Trial, and a Horizon Drift event. The standout reward this season is the Lamborghini Diablo GTR, locked behind The Trial.
Which rewards are worth prioritizing?
The Lamborghini Diablo GTR from The Trial is the headline grab this season. It's a 10-point event, which means it's the single highest-value challenge on the board, and the car itself is a collector's piece. If you only have time for one event, make it this one.
The F.R.I.E.N.D.S Horizon Drift event hands out the 1992 Mazda RX-7 with no car restrictions, making it one of the more accessible free car rewards this week. The Cosworth Your While Seasonal Championship offers the Ford Escort RS Cosworth, which is worth picking up for its 90s Retro Muscle class utility across future challenges.
The Bambo Bash Collectibles event rewards a Super Wheelspin for no car restriction, so it's an easy three points with a decent prize attached. Pair it with the Tokyo City Food Delivery Seasonal Job (also unrestricted) and you've cleared six Festival Points with minimal setup.
For players working through the broader Forza Horizon 6 guides collection, the Autumn playlist connects directly to ongoing seasonal progression, so clearing as many events as possible keeps your Festival Points total healthy heading into Winter.
Getting the most out of the Autumn season
The 90s theme running through most of this season's restrictions means your garage composition matters more than usual. A well-tuned A Class 90s Retro Supercar covers The Trial, the Mt. Fuji Danger Sign, and the Nangan Speed Trap. A B Class 90s car handles the Cosworth Championship and the Kudarizaka Trailblazer. Sorting two builds covers the majority of the restricted events.
If you're newer to the playlist structure and want to get a feel for how seasonal challenges chain together, the Blast from the Past guide is a good reference point for how early Horizon Decades tasks feed into the broader season. For players hunting free cars outside the playlist, the all 9 Treasure Car locations guide covers every hidden car across Japan's regions with no grinding required.
