Automobilista 2 Update 1.5.3 Out, Free Trial For New Content

Automobilista 2

Just a week after the latest Dev Update, Automobilista 2 Update 1.5.3 has been released. The new content that comes with it is free to try for anyone until Monday, November 27.

A long period of radio silence had preceded the most recent Dev Update from Reiza Studios. The Brazilian developer has been hard at work, which the release of Automobilista 2 Update 1.5.3 clearly shows. It comes with a long list of changes, improvements and fixes.

The AI has received special attention, and should race in a much more realistic way as of Automobilista 2 Update v1.5.3. Meanwhile, the other big focus area of the update are tire physics, which have been further refined from the v1.5 update this summer after tire tread problems had been identified. The audio engine has also been shown some love. To add, Reiza fixed and adjusted an enormous amount of small issues with some of its cars and tracks, mostly cosmetic in nature.

New Historic Content

While a lot of work has been done under the hood, the new DLC packs will likely be the attention-grabbers. As previously pointed out, Automobilista 2 Update 1.5.3 introduces two generations of the Formula Hitech class. Resembling the 1992 and 1993 Formula One seasons, these cars come with tons of electronic gizmos, including active suspension. The latter has never been modeled in first-party sim racing content before.

Additionally, more period-accurate tracks join the AMS2 roster. Interlagos gains versions for 1991 and 1993, Montreal now has its 1991 layout available, and the same year’s configuration has been added to Catalunya. The latter also sees the addition of the National layout to its modern version.

The National layout is part of the Circuit de Catalunya DLC. Meanwhile, the historic versions form the new Historical Track Pack Pt2 DLC, which costs €7,79 on Steam. The new F-Hitech cars are another DLC pack, which is priced at €6,89. Note that neither DLC pack is part of the Season Pass or the Premium Packs!

Automobilista 2 Update 1.5.3: Free DLC Trial, Time Trial Returns

Both DLC packs are available for a free trial period to anyone who owns Automobilista 2 during the update release weekend. The free trial ends on Monday, when Reiza releases a small complimentary update.

Time Trial leaderboards are already back up. Meanwhile, Reiza Founder and Lead Developer Renato Simioni stated that “physics development will be frozen from public releases until the next milestone update sometime in 2024.” Finally, Automobilista 2 Update 1.5.3 also means another setup reset due to the changes in physics.

Racing history enthusiasts should appreciate the new AMS2 content in v1.5.3. Image credit: Reiza Studios

Lifelong motorsport enthusiast and sim racing aficionado, walking racing history encyclopedia. I have been working in sim racing since 2021 after previously working with pro and amateur sports teams and athletes for a daily newspaper in Wolfsburg. Nothing gets me more excited than motor racing, especially with the beastly machines of the past. A third pedal and h-shifter are not just options for a rig, they are mandatory to me. Avid fan of the IndyCar series (modern and CART/pre-split).
