Wet weather update for Automobilista 2

Following on from the v. major update at the end of January and the subsequent hotfix update of v1.1.1.1 from last week here is another significant development from Reiza Studios.

v1.1.1.3 is labelled as a small update but brings big changes to how physics and AI behave in wet weather conditions. The updates claim to correct “various performance inconsistencies across all cars under the various combinations of tires and wetness saturation levels.”- seems pretty significant to us.

Outside of the large weather-based changes, there isn’t too much to get excited about. A couple of small art tweaks and minor physics and setup changes you’re unlikely to notice but keep going towards the ultimate goal of creating the most advanced racing simulation for Automobilista 2’s development team.

If you’re looking to take the new upgrades for a spin, Steam should push this automatically to your PC next time you sign in.

  • Disabled AJR DRS icon for V6, Honda variants
  • Reduced F1 pitstop tire change timings


  • Added car-specific overrides for AI performance on a wet track (on slicks & wet tires) & added new parameter to callibrate AI performance with wet tires on a drying track
  • Further AI callibration passes
  • Further slightly reduced AI CoG height scale to minimise chances of AI cars rolling over high curbs
  • Slightly raised AI lateral movement rate for overtaking & passing boosts (to mitigate getting stuck on straights)
  • Slightly reduced AI braking point offset
  • Reduced AI lifting off throttle over puddles to 50%
  • Slightly increased range of performance from AI drivers


  • Nurburgring: Minor art pass & fixes
