Google is preparing a significant update for Android Auto, with the latest version, Android Auto 18, currently in beta. The update, codenamed Cielo, represents the first major overhaul since Coolwalk and will introduce a new interface featuring widgets integrated alongside the main display. This design aims to maximize screen usage across various vehicle displays, including unconventional shapes like round screens. Android Auto 18 will also include a dynamic font called Google Sans Flex and enhancements to Work Profiles, allowing users to activate a work profile when connecting their phones to the vehicle. Additionally, the update will improve the capabilities of Gemini, which will leverage data from other Google services for contextual responses. Users can download the Android Auto 18.0 beta via an APK installer, but it is advised not to rely on this version for daily use due to potential issues.
