In mid-May 2026, about two months ago, Google announced a complete overhaul of “Android Auto,” its car operating system.
The overhauled “Android Auto” will feature a wide range of refreshed UI elements and new features based on the “Material 3 Expressive” design system, including personalized design elements, “Car Widgets,” and “Google Maps” displayed edge-to-edge across the dashboard.
Regarding “Car Widgets,” the addition of in-app resource codes has also been found, suggesting an imminent rollout.
Now, our original site content, “App Teardown,” has newly captured information regarding the new UI codenamed “Cielo” to be introduced in “Android Auto.”

It is likely that this new UI framework codenamed “Cielo” is indeed the UI for the completely overhauled “Android Auto.”
In other words, the new UI framework codenamed “Cielo” captured this time signifies that internal app implementation has begun in preparation for the complete overhaul of “Android Auto.” Furthermore, the completely overhauled UI may soon be rolled out to “Android Auto,” likely starting as a beta version.
