Written by Reiza Studios has released Automobilista 2 V1.6.9.91, a patch that tightens tire physics, fixes damage models on several GT cars, and locks the Historical Endurance Pack Pt2 grid behind its DLC. The update is live now on Steam and applies automatically the next time the client launches. For simracers who log regular hours in Automobilista 2, this build touches nearly every corner of the experience: tire compounds, AI behavior in the wet, visual detail on classic GT cars, and multiplayer lobby stability.
Reiza Studios continues its steady cadence of incremental patches for AMS2, and V1.6.9.91 follows that pattern closely, prioritizing fixes over sweeping new features. Anyone tracking the ongoing development of Automobilista 2 will want to check the full breakdown below before jumping back into online sessions or offline championships.
What’s New in Automobilista 2 V1.6.9.91
Automobilista 2 V1.6.9.91 is a mid-cycle patch built around three priorities: refining tire physics for GT and prototype classes, closing gaps in AI wet-weather behavior, and correcting damage models that had fallen out of sync with how cars actually respond to contact. The update also introduces a content access change, moving most Historical Endurance Pack Pt2 cars behind their DLC while leaving the Milano 55GT free for every Automobilista 2 owner. None of the changes require manual installation; Steam handles the download and patch application automatically. For drivers who run online endurance races or league seasons built around GT1, GT2 2005, GTR 2004, or LMP-class cars, this release directly affects lap times, tire warm-up behavior, and how AI opponents handle rain. It’s a patch worth reading in full before your next session, rather than assuming it’s a routine fix.
The headline change in this build concerns the Historical Endurance Pack Pt2 content. The GT cars from the 2004/2005 seasons included in that pack are now locked behind the DLC, with one exception: the Milano 55GT remains free for all owners of Automobilista 2. This brings the pack in line with how Reiza handles other paid content, leaving a single car available to non-owners as a sample of the full grid rather than pulling access entirely.
Alongside that access change, Reiza has added a default intermediate tire option for the LMP and GT 2005 classes, giving drivers a proper in-between compound for changeable conditions rather than forcing a binary choice between slicks and full wets. It fills a real gap for anyone running online endurance events where track conditions shift mid-stint, a scenario familiar to endurance racing enthusiasts who have long asked Reiza for finer-grained tire options in mixed-weather sessions.
Multiplayer lobby creation also gets a fix: the qualifying rules were displaying incorrectly during setup, which could mislead hosts and joiners alike about how a session’s quali format actually worked. That display bug is now resolved, so lobby hosts can trust what they see before locking in a session.
Physics and Handling Changes
Tire behavior received targeted attention in this patch. Reiza reduced the cold tire effects for a specific group of GT and prototype classes: GT1, GT1 2005, GT2 2005, GTR 2004, and LMP1/2 2005. These cars now reach usable grip levels faster out of the pits or after a caution period, without the exaggerated slip that some drivers had flagged as overly punishing on out-laps and restarts alike.
On the single-car side, the McLaren MP4/12 HD version had a physics issue that’s now been corrected. Reiza didn’t detail the exact nature of the fix, but the HD model now behaves consistently with the rest of the car’s setup and handling characteristics, closing a discrepancy that stood out to drivers who alternated between the standard and HD variants.
Track and Content Updates
AI behavior on wet track surfaces has been expanded to cover more circuits, so opponents on these layouts now respond to changed grip levels in rain or damp conditions instead of driving as if the surface were dry.

Bug Fixes and Stability Improvements
A batch of damage and collision fixes lands with this update, cleaning up models that had inconsistent or broken behavior after contact. The affected cars are the Panoz Esperante GTLM, Lister Storm GTM, Gillet Vertigo Streiff, and TVR Tuscan T400R. Crash outcomes and visual damage on these cars now match what actually happens on track, which matters for anyone running full-damage endurance races where a misjudged clip shouldn’t end a stint prematurely.
On a smaller cosmetic note, the Saleen S7R GT1 now has LED RPM lights and rear badges added to its model, rounding out details that were previously missing from the car and bringing it closer to the visual fidelity of its GT1-class rivals.

How to Download the AMS2 Update
V1.6.9.91 is distributed through Steam and installs automatically for anyone with the game in their library. Launch the Steam client, let it check for updates, and Automobilista 2 will download the patch before the next session starts. No manual file changes or opt-in beta branches are required for this build, and existing setups, liveries, and controller profiles carry over without issue. If the update doesn’t appear right away, restarting the client or manually checking for updates through the game’s properties menu usually resolves it.
Community Reaction
Feedback on Reiza’s community channels has centered mostly on the cold tire adjustments, with drivers who race the affected GT and prototype classes welcoming the less punishing out-lap grip. The Historical Endurance Pack Pt2 access change hasn’t drawn much pushback, since the Milano 55GT staying free gives non-DLC owners a way to still sample the era’s cars. Many of these drivers coordinate setups and race dates through simracing communities built around Automobilista 2, and the practical fixes in this patch, rather than any single flashy feature, seem to be what’s earning it a generally positive reception across sim update discussions.
