Android Auto 18 in Beta: What Does the Test Version Reveal?

TVS News AI, editorially supervised, presents Android Auto 18 in Beta: What Does the Test Version Reveal.

Android Auto 18: Cielo Design and Gemini Integration Spotted in Beta

Google released the first beta version of Android Auto 18 on October 14, 2026. What sounds like a routine update actually has substance, according to t3n: the source code of the test version contains tags like „cielo_launcher" – the clearest indication so far that Google will soon roll out the new Cielo design. The code findings were discovered by Android Sage, who dug through the beta.

What Makes Cielo Different from the Current Coolwalk

The current Coolwalk design reaches its limits especially with unusual display shapes. According to t3n, Cielo relies on a dynamic interface that automatically adapts depending on the display shape and size – content shifts or rearranges itself. The goal is for navigation to run just as smoothly on conventional landscape formats as on round infotainment displays, which are now being installed in many new vehicles. In addition, the displays can be personalized with Cielo.

The design itself cannot yet be activated in the beta – it is only visible so far through the code tags. So what you actually see in the finished update may look different by the time of release than the clues in the source code suggest.

„Gemini Personalization": AI Accesses Your Calendar from the Car

The second major new feature concerns Google's AI assistant. Under the term „Gemini Personalization", Gemini is to be integrated more deeply into the system – including access to users' Google Workspace. Specifically, t3n names two scenarios: Gemini will in future be able to read out email summaries and announce upcoming appointments from the calendar. Precisely where you want to keep your hands on the steering wheel, you'll get more information in the future without having to look at the display.

To keep things from getting lost, the beta also contains references to „Lern-Tooltips" – small introductions that show directly in Android Auto what Gemini can do there.

Cleanup: Over 200 Old Entries Are Being Removed

In addition to the new features, Google is doing some major cleanup, according to t3n. A total of over 200 older entries and functions have been removed from the software. These include dial pads for calls, templates for views, and outdated templates for color coding when accepting and declining phone calls. t3n does not conclusively explain the background – a plausible explanation is that Google wants to shed legacy issues with the jump to Cielo and Gemini that could cause problems elsewhere.

When Is the Final Update Coming – and Is It Worth a Look at the Beta?

There is no official date for the final roll-out of Android Auto 18. As usual, the final version is installed directly in the vehicle – you don't need to trigger anything manually. If your car doesn't support Android Auto at all, it can also be retrofitted in older models with just a few steps, according to t3n – especially with Cielo and Gemini in mind, it could be worth it.

Anyone who's curious can try out the beta now and get a first look at the new features. However, you should expect that individual features may disappear or change by the time of release. For everyday use on the road, this means: better to wait for the final version before relying on a new feature in your car. t3n has compiled all the details and code findings in the original article.
