Google has begun the public rollout of Android Auto version 18.1, following its beta preview in late October. While there are no visible changes for users yet, the update reveals ongoing work behind the scenes for Android Auto’s upcoming light mode and a broader redesign.
What We Know About the 18.1 Update
The previous milestone, Android Auto 18.0, launched in mid-October. Android Auto 18.1 is now moving out of beta and into the hands of stable users. On the surface, there are no major new features—rather, the update focuses on groundwork for future UI updates.
Developers have dug into the update and identified “resources” tied to dark and light mode variants. These assets include files marked for Samsung devices as well as broader Android Auto use. That suggests Google is preparing alternate themes—one darker, one lighter—for the dashboard and perhaps other components of the redesign.
Signs of the ‘Cielo’ Redesign
The codename “Cielo” keeps appearing in these latest builds. It appears to refer to a widget-rich redesign for Android Auto that features animated transitions and scaled map elements. Evidence points toward enlarged maps and effects for dashboard panels sliding in and out. Files such as “cielo_map_scale_out.xml” and “cielo_dashboard_slide_out_to_left.xml” show that animations and interface transitions are being built into the fabric of the UI.
Additional “quick settings” tiles are also being prepared, some of which may feature Samsung-specific styling or icons. These are likely to be part of the Cielo redesign, potentially giving users more control over Android Auto’s settings directly from the interface.
What’s Still Coming
There’s no firm release date yet for the full Cielo redesign or official light mode. While the assets and animations suggest Google has made substantial progress, these changes are still in development and not yet enabled for general users.
Until then, Android Auto 18.1 remains mostly invisible to end users—there’s no change in how the app looks or behaves in daily use.
What this means: Android Auto 18.1 is a preparatory update—not one with flashy new features, but full of foundations. The inclusion of light and dark theme assets points to more customization ahead, while the extensive code-level work under the ‘Cielo’ codename suggests Google is serious about revamping the UI. Drivers and tech fans should watch for future updates where these features become active. The rollout signals that a more modern, flexible Android Auto experience could be on the horizon.
