Automobilista 2 v1.5.5.2 Introduces Less Forgiving Tires, All-In DLC Pass

Automobilista 2

Reiza Studios has deployed a small update to introduce Automobilista 2 v1.5.5.2 – and with it, another refinement to its tire model, as well as a new option for those who want all DLC for the sim.

The recent batch of updates have seen Automobilista 2 make big strides while also releasing exciting content. The Formula HiTech classes are a first for first-party sim racing content, and the first part of the Endurance Pack laid the groundwork for modern endurance racing featuring LMDh and GT3 cars.

Now, a relatively minor update introduces notable changes to select cars. Automobilista 2 v1.5.5.2 most notably sees tire tread adjustments for select cars, making them less forgiving on the edge of grip. This should adress a common issue some playes have with AMS2, feeling that the slip curves were too generous.

Reiza Founder and Lead Developer Renato Simioni explained the thought behind the update on the studio’s forums. “It is true that AMS2 tires have historically allowed for too high angles to be sustained a little too long – that issue has been reduced to a minimal if not quite completely eliminiated with v1.5 and the subsequent refinements, the latest of which just deployed with v1.5.5.2. To the extent the issue persists on some tires we’ll continue trying to iron them out, after all, the point of the exercise is to simulate reality.

Simioni also addresses the classic “more challenging to drive equals more realistic” argument that keeps popping up in discussions from time to time. “A problem here is that many sim racers have been conditiond to believe race cars on modern slicks don’t allow for any sliding at all, are never subject to turn-in oversteer so long as the car is neutral and are incapable to sustain a powerslide for longer than half a second.

Even if we completely eradicate that slightly forgiving plateau at the top of the slip curve in AMS2, they’ll always be a little thrown off by its handling because their perception have been skewed.” Reiza’s CEO also makes it a point to note that his words should not be taken in a “we are right, you are wrong” kind of way: “This isn’t to detract from valid criticisms of our own tire modelling – we wouldn’t keep adjusting it if we felt everything was dandy.

Given the inherent imperfections of all tire models, there’s always going to be a degree of subjectiveness as to what flaws our brains are better able to translate. Personally, I’d rather drive AMS2 with tires from even two years ago because it’s just more organic, but I totally see why others would prefer something that felt more like a train on rails that has to be driven carefully not to derail.

Automobilista 2 All-Inclusive DLC Pass

As the DLC Season Pass will not see any new packs added to it (save for the Racin’ USA bonus pack, which does not have a release date yet), a new option for anyone wanting all current and future content for AMS2 will be introduced. This will cover any existing DLC at the time of purchase.

Two versions of this All-Inclusive DLC Pass will be available. One is geared to those who already own the Season Pass, the other at thosw who own the Premium Track Pack and Premium Expansion Pack, offering a lower price. Both will offer a 15% discount to new content. New users can grab either version.
