More news of the incoming update for Automobilista 2 . This is the new V1.6.9.9 for Reiza’s sim and introduces several new features. Let’s take a look.

Reiza Studios has been teasing a series of gameplay clips showing what’s coming in the upcoming V1.6.9.9 update. While the version number looks like a minor step, the changes under the hood are substantial. The focus of this next patch is split between expanding the simulator’s historical grid with the Historical Endurance Pack Pt2 DLC and introducing a much-needed overhaul to wet-weather physics and AI behavior.

New Grid Additions: Historical Endurance Pack Pt2

The upcoming DLC is diving straight into the mid-2000s sports car era. The preview clips showcase a varied selection of classic GT machinery that defined endurance racing around 2004 and 2005. The roster includes some highly requested cars:

  • Ferrari 550 GTS Maranello: The front-engined V12 that became an absolute fan favorite in global GT championships.
  • Saleen S7R: The low, wide American supercar with its unmistakable V8 rumble.
  • Lister Storm GT: The heavy-hitting British entry known for its massive Jaguar-derived V12.
  • Maserati GranSport Trofeo & Gillet Vertigo: Smaller, unique additions that flesh out the grid variety.

According to Reiza, these cars aren’t just getting generic group physics. They are implementing dedicated physics profiles tailored to specific manufacturers to make sure each chassis behaves accurately compared to its real-world counterpart.

A Massive Wet Weather Upgrade

One of the most technical teasers shows a time-lapse of a 10-lap race transitioning through different weather phases. Reiza has reworked the core visual elements for rain, updating the shaders, particle effects, textures, and lighting to make storms look more realistic.

More importantly, the way the track surface dries has been completely re-engineered. The video shows a smooth transition from a fully flooded track to a damp one, with a clear, realistic dry line forming as cars lap the circuit. This means players will have to dynamically search for grip and manage tire temperatures as the racing line evolves in real-time.

Smarter AI That Respects the Rain

Racing against the computer in the wet is also getting a fundamental fix. A dedicated clip demonstrates the new AI “wet line” logic. Historically, sim racing AI tends to stick to the standard racing line regardless of weather. In V1.6.9.9, the AI actively recognizes that the rubbered-in dry line becomes incredibly slick when wet.

As a result, the AI now shifts its line outward to find grip on the unrubbered tarmac. The clips also show the AI steering around heavy standing water and deep puddles on the straights to avoid hydroplaning, making offline wet races look and feel significantly more natural.

Release Details Coming Soon

Reiza hasn’t dropped the exact release date for V1.6.9.9 yet, but they confirmed in their posts that official timing and more details will be shared in their upcoming Summer Dev Update. Given the depth of the weather and AI overhauls shown in these clips, the community won’t have to wait too long to get their hands on it.
