Automobilista 2 1.6.6.1 update adds follow-up fixes and tweaks

We’ve logged Automobilista 2 v1.6.6.1 as a follow-up update focused on additional fixes and improvements after the previous release. The official post also flags an audio issue: if in-game sound seems muffled or muted, users should check AMS2’s Windows Volume Mixer level and verify the in-game headphone mixing setting is appropriate for their device, per the official announcement.

What changed

Fixes

• Follow-up patch with additional fixes and improvements.
• Developer troubleshooting note for muffled or muted audio: check AMS2 volume in Windows Volume Mixer and confirm headphone mixing is set correctly in-game.

Cars

• Alpine A110 GT4 Evo: minor engine torque curve adjustment.
• Ligier JS2-R: front brake torque adjusted.
• Minor cold-tread effect adjustments for GT4, G55 Supercup, and Ligier JS2-R.
• Further adjustments to slick wetness effects.
• Aston Martin Vantage GTE: fixed interior parts clipping through the windshield.
• Corrected “look back” camera position for new cars.

AI

• Further adjustments to AI fuel strategy parameters in Endurance classes.
• Increased AI cold-tire performance losses for Ginetta G55 Supercup and Ligier JS2-R.

Tracks

UI & HUD

• Fixed missing Ligier European Series leaderboard/HUD icon.

For league ops, we should notify drivers about the audio workaround and rerun any current AMS2 combos that depend on endurance AI, GT4/Ligier/G55 behavior, or Nürburgring visual consistency before race night.
