The star of this update is undoubtedly the 2022 Noble M600 Speed.
For those who live for raw, unadulterated driving experiences, the Noble M600 is a holy grail. Unlike many of its contemporaries that rely heavily on electronic aids, all-wheel drive, and hybrid systems, the M600 is a throwback to analog motoring.
In a game often dominated by all-wheel-drive meta cars, the Noble M600 Speed offers a purist experience. Expect to see this British beast tearing up the drag strips and drifting through the dunes as players master its high-power output.
Unlike seasonal Series updates that simply rotate weekly playlists, Rune Part 1 is a foundational patch. The "Rune" title likely refers to the graphical and auditory "glyphs" that now appear on wet tarmac and sandy ruts. Playground Games has hinted that this is the "calm before the storm," setting up the physics engine for a major expansion tease at the end of Part 2 in four weeks.
Key Narrative Hook: A new Horizon Story titled "The Archaeologist's Gambit" has appeared on the map near the Ek' Balam ruins. It involves decoding ancient symbols (Runes) that, when scanned, alter the weather patterns in specific biomes.
Within the game files of v1.671.650.0, references to four new vehicles were found under the folder [CAR_DATA/PRIMORDIAL]:
These are not DLC pack cars—they are earnable via the new seasonal championship "Echoes of the First Horizon."
The forzahorizon5updatev1671650runepart1 represents a fascinating snapshot in Forza Horizon 5's history. It is the "Phantom Menace" of the series—a patch that promised more than it delivered on the surface, but underneath, it was laying the groundwork for the next six months of content.
For the average player, this is just an old update. For the digital archaeologist, it is a treasure trove of cut content, unused voice lines, and a glimpse into Playground Games' internal naming conventions (Rune -> Hidden Horizons -> maybe an actual Mythology expansion?).
If you have this version sitting on an external hard drive, keep it. It is a piece of gaming history. If you are trying to install it to play today, update to the latest version—the 2024 Eclipse DLC is worth the drive space.

While many players are currently immersed in the seasonal "Horizon Retrowave" and "Modern Horizons" content, this specific technical release—often identified in community circles by its "Rune" part designation—focuses on the "under-the-hood" mechanics that keep the festival running smoothly. Key Technical Improvements
The v1.671.650 update primarily targets legacy issues reported across both PC and Xbox platforms. Key focus areas include:

Historically, these labels often refer to specific file-packaging structures or segmented deployment phases used to manage large-scale asset updates without requiring a complete re-download of the game’s 100GB+ footprint.
For enthusiasts, this means more efficient patching and less downtime between your next PR Stunt or Seasonal Championship. What’s Next for Horizon? In a game often dominated by all-wheel-drive meta
