Automobilista 2: Patch 1.6.3.6 Adjusts AI Fuel Parameters

Article Discussion
Automobilista 2 Hotfix 1.6.3.6.jpg
A new patch for Automobilista 2 has arrived: V1.6.3.6 mostly addresses AI fuel parameters that affected their strategy, but also fixes and recalibrates a number of other elements.

With more frequent updates on the horizon in 2025 compared to the previous year, Reiza Studios has released what should be the final small update of the v1.6 development cycle of Automobilista 2.

Several sim racers had noticed AI drivers not being able to handle Daytona's turn one - the road course variant, that is - all that well, often crashing into the inside wall. The patch should prevent this, at least most of the time - just like it should keep the AI from making weird pit stop strategy decisions. Furthermore, a few classes have received performance calibrations, while Reiza has also fixed some minor visual errors as well as the ARC Camaro being unable to start its engine since the most recent update.

Other minor changes concern the tire treads of all karts plus ten further classes. You can find the full extent of the changes in the patch notes below.

Automobilista 2 v1.6.3.6 Changelog​

UI & HUD​

  • Updated names & logos for Karting classes
  • Fixed missing leaderboard class colours for both LMP2 gens

PHYSICS​

  • Further minor tire tread adjustments to karts, LMDh/GTP, LMP2, P1 (both gens), F-Ultimate Gen2, Copa Classics, ARC Camaro, Caterham 620R, Superlight & Supersport
  • F-Ultimate Gen2: Further throttle map update
  • Fixed player control issues with F-USA Lola Gen2 & Gen3 oval variants
  • ARC Camaro Fixed issue with engine not running
  • Minor tread thermodynamic adjustments to kart tires
  • Corrected further inconsistencies in F-USA Gen2 & Gen2 Lola oval variants
  • Disabled redundant rear toe rang for karts
  • Increased draft effect to ramp from 100m (over previous 75m)

AI​

  • Adjusted AI pitstop estimate losses & tire wear thresholds for all Endurance classes & F-USA oval variants so AI drivers in those classes are generaly less likely to find pitstops worthwhile until it is running low on fuel
  • Reduced amount of extra fuel AI will carry as a safety margin in qualifying & last stint of races
  • Reduced fuel safety margin threshold under which AI will pit for fuel in races
  • Reduced amount of fuel AI carries when fuel consumption is disabled
  • Calibrated AI simulated session times for Super V8, Stock Car 2019-2024, Copa Montana, P2, P3, P4
  • Adjusted AI corridors at Daytona road courses to minimise chances of AI hitting the inside wall going into T1
  • AI tire wear calibration pass for LMDh, GT3 (both gens), GT4, GT Open, GT1, Group C
  • AI dry performance calibration pass for Copa Classic, Caterham Supersport, Caterha, Superlight, ARC Camaro
  • Further adjustments to mitigate chances of AI karts rolling under hard cornering

AUDIO​

  • Nissan R390 GT1: fixed missing sound for cockpit camera in replay and monitor

VEHICLES​

  • Set historic safety car models for F-Junior, Vintage Touring Car Tier1, BMW M1 Procar, Group C, Group A, GT1, F-USA Gen1-3
  • Fixed external mirror material for ARC Camaro, BMW M4 GT4
  • Removed driver HANS device for all Karting classes
  • Cadillac V-Series R: removed fresnel mapping to external carbon material

Just prior to the hotfix, Reiza Founder and Lead Developer Renato Simioni has revealed that Automobilista 2 will see more frequent updates throughout 2025, which will include new content "pretty much every month". Furthermore, new features will also be introduced to spice up race weekends and make players reconsider how they approach a session.

Overtake. Where all the forum users that got butt hurt by Renato go to bash the game because they feel it's their personal mission to share their dissatisfaction with the world. Renato lives in their head. It's entertaining to say the least.

Poor customer service leaves a bad taste in your mouth... They got paid to do a job and made their choice not to do it...

But the results seem to pay off, as they seem to listen more when you complain publicly than when you waste your time with the forums...

Name one dev which isn't further adjusting and improving their sim as long as it's still alive and taken care of.

It's interesting what you know, without knowing anything about internal processes. :)

Hm,i can't confirm this.Are you useing "custom AI files" or play a different game as i do....:thumbsdown:
Click to expand...
I am using custom AI files. Not sure if that's the source of the problem, can run another test.
Could you share your session config?
I am using AI Skill 119%, AI Agress. Low and AI Mistakes OFF. I think those are the potentially relevant settings.

EDIT: Interestingly, the bus stop seems OK without the custom AI files. @Dady Cairo , do you know what setting causes the issue? I would like to be able to do this race but still would like to use custom files.

The turn one pileup at the start isn't fixed, unfortunately.

Ah so then have fun and don`t blame the game.
Everybody knows that this won't work.
And you did't told it that you were using them in offical bugs forum.
Such a shame

No,as i'm only a beta-tester and no coder.

As someone who is a MSFS player, I have come to the conclusion that wouldn't waste my money on professional community managers.

This is a very good question. Used to love the formula junior in 1.5.. Now.. not so much. Having said that, I wonder what any of the sims use for their target tire models. Influencers? Local Bro Club? Dice?

A bit offtopic but I've been waiting since 2020 for MSFS20 to fullfill its promises before buying it (X Plane 12 user here), well it will never do it, although the announced 10 years support, you'd better buy a full new game 4 years later! And still far from its promises. I think I'll have to wait for MSFS30 or, better, X Plane 13 (or a miraculous X Plane 12 update, the game just needing better buildings and a well native implemented ground textures streaming). Offtopic rant over...

I think it must be hard to get good feedback and work with it for deceloppers. By watching different youtube channels of real life racing drivers, who also are simracers, you get opposite feedbacks and sometimes some contradiction between videos or in the same video. It doesn't sim theycare bought, they just have different ways of feeling the cars and the translate differently their knowledge into simracing, so it is not easy to get the right feedback. For example, a real GT3 driver has stated his sim to train at home is LMU, but he pointed out that something was wrong at low speed, the car not having enough wait and then too much slidy, with not enough force in the FFB. At higher speeds there is still some weight missing but it is the closest to reality in his opinion. For me it means it shares the same aspect I don't like with rfactor2, this low speed slidy aspect of the driving and the lack of weight in general, that I don't experience in other titles. But it seems that most simracers state that LMU is the best out there. And this real drover just deals with it, although he knows it is not perfect. But for me, this specific issue, for my driving style, is a big one (it has always been the same with any ISI title ; I say ISI because Simbin got rid of it in any of its ISI engine based game). Does it means the physics should be changed although most users have been satisfied with that for 10 years of rfactor2 and now in LMU and when other titles less prone to this issue are often bashed by rfactor2's fans? Feedback is difficult to interpret and bringing adjustments may brings image issues and communication work. Not an easy task...

20 years I support ISIMotor absolutely my favourite driving physics.

I just got to say 2 words "Epic Fail" about a single issue and you go from fanboy to hater.

we know ACC use only pirelli zero DHE tires (SRO official tire).
data came from there, dev said.
started with the 2018 model specs and updated twice in 2020 and 2023 with v1.9.

i know IMSA uses only michelin, so, at least in latest DLC GT3 models (called gen2 in AMS2 for some reason) should based there i suppose.

Official data has to be converted before being input in a game's model. There's ways for interpretation. And if the model has less or more variables than the available data, there are many ways of misinterpretion. That's were the whole point is. If it wasn't, all sims would feel the same.

One thing I've noticed is if you do an offline championship you can't skip qualifying so you have to sit through the whole session length which tbh is stupid.

All I do is offline custom championships and I have never had to do that.

And karting is still terible, one of the worst there ever was in games. Btw, when I was living in Brazil, I was numerous of times on karting track Granja Viana, and AMS2 misses lots of layouts, which existed back then (15yrs ago), and I belive they still exist.
Click to expand...
Well they don't have to provide all layouts, they still provide more than anyone else with the circuits they do release.

OK so not related to the fueling fix, rather had a quick jump-in with latest patch 1.6.3.5 in a newer class than my usual hobby of classic vehicles to rein in:

Time Trial event in the Ginetta G40 Cup @ Londrina Long.

Now, that was fun!

And this tiny low-powered playtool seems much suitable for the Madness single Pivot immersion trends.
Sadfully only very few minutes availabe, but certainly a car I have overlooked and cannot say anything bad about the sim feeling. It really suits me!
