Written by Kunos Simulazioni has rolled out Assetto Corsa EVO hotfix 0.6.1 on Steam, a small but focused patch aimed at cleaning up bugs and inconsistencies that surfaced after the previous update. The changes are live now for all Early Access players, and while there’s no new content in this build, several fixes touch things simracers run into every session — from fuel density mismatches to a crash on session entry.
What Happened: Assetto Corsa EVO Hotfix 0.6.1 Overview
Hotfix 0.6.1 was published through the official Steam News channel for Assetto Corsa EVO, the Early Access title from Kunos Simulazioni distributed via Steam with support from 505 Games. The update doesn’t add new cars or tracks. Instead, it’s a maintenance pass: fixing regressions, correcting car-specific data, and polishing a handful of UI and visual issues that the community flagged after the main 0.6 update.
The patch is now the default build on Steam, so anyone launching the game will automatically be pulled onto 0.6.1 without needing to opt into a beta branch. For a broader look at how Kunos has been handling the Early Access rollout, our Sim Updates coverage tracks every patch as it lands.

Key Changes Breakdown
Most of these fixes fall into two buckets: things that broke the sim experience outright, and things that were quietly wrong under the hood. The session-entry crash and the fuel density sync are the clearest examples of the first category — both directly affect whether a race session can even start or run correctly. The rest are refinements that improve accuracy and immersion without changing how the game plays at a fundamental level.
Physics and AI Adjustments
Three cars received specific physics corrections in this hotfix. The Porsche Cayman GT4 CS MR got a complete overhaul of its aerodynamic map, changing how it behaves at speed and through fast corners compared to the previous build. The Mazda MX-5 Cup received a smaller correction to drag and power figures — a tuning pass rather than a rework. The Ferrari 288 GTO now has an increased maximum steering angle, addressing a limitation that affected tight hairpins and parking-lot maneuvers. The Cayman GT4 CS MR received the most substantial revision of the three, but all three bring per-car data closer to what Kunos intends for each model.
Bug Fixes and Stability
On the stability side, the headline fix addresses a crash that occurred when entering a session — a bug that could interrupt a race weekend before it even began. Kunos also corrected a misread value tied to rain-related functions, improving how wet-weather systems behave in-game. The fuel density synchronization across all cars closes a gap where different vehicles were calculating fuel consumption inconsistently, an issue that matters for anyone running endurance stints or fuel-strategy races.
Why This Update Matters for Sim Racers
None of the individual fixes in Assetto Corsa EVO hotfix 0.6.1 are headline-grabbing, but together they address the kind of friction that erodes trust in an Early Access title. A crash on session entry is the sort of bug that stops a race weekend before it starts, and inconsistent fuel density across cars undermines strategy-focused racing — both are now resolved. The aerodynamic revision on the Porsche Cayman GT4 CS MR is worth noting for GT4 regulars, since it changes the car’s on-track behavior compared to the build most players have been running. The UI tweaks are minor by comparison, but they reflect steady, iterative maintenance rather than a single sweeping rework, which is generally the healthier sign for a title still finding its footing in Early Access. Taken as a whole, this hotfix is evidence that Kunos is actively working through community-reported issues instead of letting them pile up between larger content updates, a pattern worth watching if you’re deciding whether to invest more track time now.
Visual corrections at Sebring and Nürburgring, along with the windshield mask fix on the Audi R8 GT4, fall into the same category: not gameplay-changing, but a signal that reported issues are being triaged. Simracers who track every Assetto Corsa EVO update will recognize this as a fairly typical hotfix cadence for the title so far.
How to Update and Verify Your Version
Steam applies hotfixes automatically, so most players will already be on 0.6.1 the next time they launch Assetto Corsa EVO. If the client doesn’t update on its own, restart Steam or manually check for updates through the Downloads tab in the Steam client. You can confirm you’re on the latest build by checking the version number displayed in the game’s main menu against the 0.6.1 changelog published on the official Steam News page for the app.
Since this is a straightforward hotfix layered on top of the existing 0.6 branch, there’s no need to opt into any beta or experimental build to receive it — it’s part of the standard Early Access release.
