Playground Games dropped Update 375.327 for Forza Horizon 6 on June 15, 2026, and it is one of the most impactful patches the game has seen since launch. Version 375.327 is live now on Xbox Series X|S, Windows PC via the Xbox app, and Steam.

Feature CategoryKey Patches & Stat MetricsStrategyMeta & Progression Verdict

Drag Tire Nerf

(Upgrades & Tuning)

• Physics Overhaul: Strips away lateral cornering grip completely.

Road Discovery

(Japan Map Fixes)

• Added an explicit Roads Driven % tracker to the Region Overview.

• Unlocked 2 bugged, permanent ghost nodes.

Drivatar AI

(Race Behavior)

• Rebalanced overall rubber-banding difficulty tracking.

• Fixed rocket-start launch anomalies.

None required. Shorter grid sprints feel significantly fairer since AI cars no longer trigger unrealistic speed bursts at launch. evens out tighter competitive class brackets, preventing the AI from breaking out into uncatchable early leads on grid starts.

Graphics & Audio

(Visual Polish)

• Patched load screen crashes on Xbox Series X

S.

• Restored PC High preset rain particle layers.

Upscaling Cleanup: Street Race red smoke pixelation artifacting has been smoothed over. Fixed Photo Mode grid fence artifacts.

Two changes are going to affect almost every player immediately. First, drag tires have been nerfed in a way that will break a large number of popular circuit and time attack tunes. Second, the Horizon Play XP curve between Levels 26 and 100 has been cut significantly, and players who had already reached Level 32 are being pushed straight to Level 100 with all badges and the “Maxed Out” achievement included.

The Drag Tire Nerf Explained and Why It Matters for Leaderboards

This is the change that has players talking. Before this update, drag tires were reducing PI (Performance Index) significantly while still offering enough lateral grip to corner effectively. That combination made them an easy way to gain a PI advantage in circuit races, road routes, and time attack events. Playground noticed, and now they have fixed it.

Here is exactly what changed:

  • Drag tires now have significantly reduced cornering performance. They behave the way drag tires should: great straight-line grip, poor lateral grip.

  • The PI cost of drag tires has not changed. If your tune was A 700 before, it is still A 700. But it will now corner much worse than before.

  • Drag racing performance is unaffected. At actual drag events, the change does not touch your times.

  • Leaderboard times set using drag tires in non-drag events will be removed. Playground has confirmed these will be progressively wiped as they are identified.

If you built a circuit or time attack tune around drag tires to abuse the PI system, that tune is now dead weight. You will need to rebuild using sport, semi-slick, or track tires depending on your class and target event. The community had been calling this out since May, with players on Steam forums reporting that drag tire builds in A and S1 class were creating unfair gaps that no conventional tune could close.

What to Rebuild With

For circuit racing and road routes, switch to sport compound or semi-slick tires for most builds in A, S1, and S2 class. Drift and street events stick to drift compound. For drag events only, drag tires remain the right call.

Horizon Play XP Changes: Level 100 for Thousands of Players Overnight

The second massive change involves Horizon Play progression. Reaching Level 100 (the “Maxed Out” achievement worth significant Gamerscore) required a grind that players had been calling extreme since launch. Threads on Reddit and TrueAchievements from as recently as May were describing the XP requirements between the mid and late levels as punishing.

Playground has now fixed that. Here is what the patch does:

  • XP required between Level 26 and Level 100 has been significantly reduced. Getting to max level will take considerably less time than before.

  • Players already at Level 25 or higher will see their level jump automatically when the new XP requirements recalculate on their account.

  • Players who had already reached Level 32 are being set to Level 100 immediately. All associated badges and the “Maxed Out” achievement will unlock when they next log in.

A bug that was preventing some players from unlocking Level 12 without entering an extra race event has also been patched.

If you are below Level 25, you will not see an automatic boost, but the grind from here is now shorter than it was. The “Maxed Out” achievement is now reachable in a realistic session count rather than requiring weeks of dedicated farming.

Festival Playlist Bugs Fixed, Plus Retroactive Points From Series 1

The Festival Playlist section of this patch is dense and worth reading carefully if you track challenge completions. Several bugs were causing real progression loss:

  • Some daily challenges and a seasonal job could be completed ahead of schedule, which was not intended behavior and has been patched.

  • Completed weekly challenges from a previous season were sometimes losing their “Completed” label, making them look undone.

  • Daily challenges across multiple seasons were not unlocking for certain players.

The most player-friendly fix here is the retroactive one. Playground is awarding all missed Daily Challenge Points from Series 1 to every player who participated during that season. To claim them, go to the Playlist History section of the Festival and open Series 1. The points will be waiting there.

Drivatar AI and Race Start Behavior Fixed

If you race against AI frequently, you have probably noticed the opening seconds of a race feeling inconsistent or outright wrong. This patch improves difficulty balancing across AI opponents and fixes a specific issue with Drivatar behavior at race starts.

Race starts matter a lot in shorter events where an early gap of two or three positions is hard to recover. Getting that behavior to feel fair from the first second makes a real difference, especially in the tighter class brackets.

Road Discovery Gets a Useful Upgrade

For players chasing 100% map completion, the Region Overview now shows a Roads Driven percentage. You can now see at a glance exactly how much of Japan you have covered in any given region, instead of guessing which roads you missed.

Two road nodes that were permanently stuck as undiscovered no matter what you did have been fixed. Inconsistencies between the mini-map and the world map in Road Discovery have been resolved too. If you spent an hour hunting a mystery missing road before this patch, you were probably hitting one of those bugged nodes.

Visual Fixes Worth Knowing About

Playground fixed graphical corruption during loading screen transitions on Xbox Series X and Series S, particularly during Horizon Stories and after Monthly Rivals Events. Several other visual issues have been cleaned up:

  • Motion blur artifact on the 2001 Mitsubishi Lancer Evo VI GSR TM Edition has been resolved

  • Photo Mode lighting inconsistencies when switching between times of day are fixed

  • Green artifacts appearing when shooting through metal mesh fences in Photo Mode are gone

  • Rain particles were disabled on the “High” graphics preset on PC and this has been patched

  • Pixelated red smoke in Street Races when using upscaling has been improved

Audio Fixes

Audio performance on lower-specification devices has been improved. On the car side, the volume of the air vents on the 2010 Lamborghini Murciélago LP 670-4 SV has been adjusted. Small fix, but specific enough to show the team is paying attention to individual car audio quality.

What to Do Right Now

If you use drag tire tunes in any event outside a drag meet, rebuild them before you race. Your times are already slower and any leaderboard entries built on those tunes are at risk of being wiped.

If you are grinding Horizon Play, log in and check your level. Players at Level 32 and above are already at Level 100. Everyone above Level 25 should see a jump. If you were in Series 1 and missed daily challenge points, visit Playlist History and claim them now.

The next Season (Summer, Series 2) starts Thursday, June 18, 2026 at 2:30 PM UTC. Keep an eye on the Series 2 Festival Playlist for new cars and challenges. Playground has not confirmed what comes next in terms of balance changes, but with drag tires addressed, attention may now shift to any remaining PI manipulation strategies in other tire classes.
