With the first minor update to Automobilista 2 in 2025, Reiza Studios introduces revisions to the oval variants of the F-USA cars, among numerous other fixes and adjustments.

After the long-awaited release of version 1.6 in late November of 2024, you could have thought that Reiza Studios might be in for a lengthy break after working on the milestone update throughout most of the year. We are not in on their staff's vacation schedules, but the Brazilian studio certainly has not been inactive. The result: Automobilista 2 is updated to version 1.6.3.5.

While not a major update in the grand scheme of things, the list of fixes, adjustments and revisions is quite long, similar to the recent update that Studio 397 and Motorsport Games released for Le Mans Ultimate. As a result, it is not necessarily easy to identify a particular highlight, but those with keen eyes will spot something in the release notes below that oval racers in particular will most likely welcome.

Automobilista 2 v1.6.3.5 Karts.jpg


All generations of the F-USA cars - that means the 1995, 1998 and 2000 IndyCar/CART seasons plus the semi-fictional 2023 IndyCar - received revisions to both their aerodynamics and suspension models on their oval variants in order to improve their comparatively lacking behavior on the speedways. This also includes the option to set positive camber in the car setup, as well a correctly-sized fuel tank for the 1995 (Gen 1) cars. The road course variants have also seen minor adjustments to iron out inconsistencies between the two variants.

Other classes that saw adjustments include Formula HiTech Gen 2 in order to fix excessive power figures for two low-downforce variants, both Formula Ultimate (modern F1) generations with new throttle maps, and all classes of karts, among others.

Maximum Pit Speed Limit Increases​

Meanwhile, enthusiasts of vintage racing will be happy to read that the maximum configurabl pit speed limit has been raised to 240 kph from 200 kph - although an 'unlimited' option would be even better to simulate the days where pit speed limits were not even on anyone's mind yet.

Furthermore, several UI elements were also subject to fixes to iron out bugs, and replays should look slightly less silly in some instances as the excessive steering range and lock that would occasionally pop up should be a thing of the past now.

AMS2 justs get better and better, and when the IMSA content is completed it will be yet another step, there were rumors of a BMW CSL to race against the 911 RSR and Corvette too, once can hope ... but thanks to Reiza for continued improvements on this excellent product!

Completed? Have they actually said there will be anymore IMSA packs? I'm pretty sure the last one was the last one they were releasing. I'm aware there are cars like the Acura, Mustang etc missing but I haven't seen them confirm there will be anymore.

In my mind, this is such a big bug with the new content no less, that the patch should not have been released yet - Or it should not have been the default game version, but a testbranch

Sadly after they made the switch, the bug is now also in the old version - So looks like im going to take a brake from AMS2 till they fix it at some point

I’ve wasted almost 30 mins of my time trying to recreate this issue, out of about 20 attempts I had one incident of this penalty bug when starting at the back , otherwise it’s actually all works a lot better than I remember when using auto rolling start .

The only thing I can deduce from it all, was it only occurred the One time it placed me on the left ( inside lane ) .

So this seems a very minor bug ( ie Not at all game breaking ) but hopefully should be easily corrected if the any other reports can confirm the same behaviour of grid placement on left side leads to penalties.
In the meantime maybe do a qualifying session or start in midfield.
If you can make much headway starting at the back then your Ai settings are probably too low for a good race anyway.

It'll be interesting to see how this turns out on the ovals which have long been overdue work...

The GT3s have gone backwards from the 1.6 forwards movement from those who care about GT3s... So hopefully they didn't dentist the CART cars as well...

Can't checkout AMS2 for a bit. Can you elaborate in what way do you think the GT3s went backwards?

I am allergic to GT3s due to the old school driving aids in most titles.. However according to those who thought they were heading down the right path for 1.6 with the GT3s, the GT3s have gone the other way back towards the feel of 1.5... There's been quite a few complaints in my circles about them being too forgiving and predictable after this patch...

The dentist class can be whatever Reiza wants it to be as far as I'm concerned because I'll actively avoid them, but to a lot of people that's the measuring stick for sim racing games...

I just hope the CARTs have gone the right direction and a few of the game breaking bugs that effect me are cleared...

From my experience ..
The GT3s and many other classes given “ minor” tread adjustments have only had a subtle shift for the better.
Now they are more consistent in grip between each end of the car. , the front doesn’t understeer early in turn anymore and can hold a line through the turn better without extra input , the rear end tracks the front more predictably and and if you are smooth with inputs and don’t out brake yourself they remain in Steady balance. But if you go too fast into turn they will rears bite you back , just less slightly abruptly, they won’t behave like 1.5 and just take the abuse and allow power slide at high throttle . , you will spin .
If your in a steady state on entry but still carry too much speed the car will drift a little towards understeer and all four slide And you will run wide . . , especially if your tyres aren’t in the optimal range.
All in all there well balanced and predictable below the limits , and most should find them manageable. Finding the extra second of lap time on the edge will be the difference between the gentleman and the ace . .

What i have heard about real driver of GT3's, these things are called tanks compared to open wheels or older race cars.
They go wide instead of throwing their rear end when carrying to much speed.

So, that's enough now.
This is just not going to work.
Thousands of bug fixes since it was released.I'm done.
I'm going to throw away all my equipment.
End, out, over, zip, tschüß, au revoir, auf Wiedersehen, nada.
How can you not notice such a blatant error?
The spelling mistake in the German translation is still there. Ohhhhhhhh my god.
It says "Boxengeschwidigkeitbox" but it's actually called "Boxengeschwindigkeit". An absolute no-go.
That's completely over, of course, some have probably noticed, irony.
Long live AMS2.

Ok, now this is starting to get a bit hard now, with all these things happening in the sim title landscapes.

My addiction is starting to override my body's cries for just a little sleep for the 5th day now. But I just have to be in it again this night. Yet again. Can't miss nor postpone it my spine says :D

OK!
Had to give up my bad habit of nightly sleep-stealing activities for AMS2, as another, newer sim just "got in the way" :D

But on the fly today in public traffic, waiting in a station lobby (somewhat with a little less havoc and confusion than a typical AC lobby :p), I just took out my laptop.
So pure keyboard AMS racing, this with authentic aids.

First into the content of which is advertised in above article; Indy Gen-1 at Auto Club oval.
I haven't even thought about it with pit speed before, but it's been worked on.
Except that the consequences are still not that severe, since it's inspired by online mitigation with ghost competitors where nothing happens. And missing the panicked pit crew running in and out between the pitting cars.

And so to a little off-topic in relation to this article.
I've been away from Formula Junior for some time. Then took a full race event at Kyalami Classic - with full grid, forced pit stops and mixed a bit with Brazilian F3 and GT Classics and turned up the AI "confusion" after the introduced 1.6 features here.

During the practice session I was seriously hit by the disappointment of the "single pivot" feeling again - of course in a no-wings single seater it is the most prominent, but still.

I will say though that there was extreme understeer. And you could keep on waiting, waiting and waiting to step on the gas even in the fast corners. And the tire reaction I have to credit Reiza for really moving to something authentic. And the AI part seemed really alive, especially in turn one.

I actually think it is one of the best sim events I have had via keyboard driving. The disappointment of the "single pivot" simulation quickly disappeared when I first got fully involved with the other things.

Wow! :inlove:

It does have a lot of critics for very good reasons...

It wasn't just rushed vapoware level work during the pCARS years... The Madness engine itself is a lemon... It's buggy on many levels that even a talented group like Reiza can't get to the bottom of many of the issues after many years on the project...

You can skip the bug with a manuel rolling start. But if you do a auto it will give you an penalty.

When restarting the race 5-6 times, i could get 1 working race without it

I tried in LMDh , LMP2 and GT3 all the same bug when starting last

Funny simcade, after 1.6 no flat spot and tire wear. All the time a mass of bugs and underdeveloped AI.
