The "glow" look in the context of the Google Assistant refers to a redesigned interface that features a set of Google's colors at the bottom which glow while the user is giving instructions or asking questions. This design was first introduced during the Pixel 4 era when Google introduced the "new" Assistant, which was faster and more accurate. The "glow" look has expanded to the rest of the Android world and is currently seen on smartphones that haven't yet switched over to Google Gemini3. The update for Android Automotive brings the Assistant in line with the experience on Android Auto, adopting this "glow" look.
The primary difference between Android Automotive and Android Auto lies in their functionality and integration with the vehicle. Android Auto is an app that mirrors your Android smartphone on your car's infotainment system, requiring a compatible vehicle and stereo system4. It offers features like hands-free calls, weather updates, playing music, and navigation but is not integrated into the car's system.
On the other hand, Android Automotive is a fully-featured operating system developed by Google in collaboration with Intel. It is installed directly on the vehicle's head unit and offers deeper integration with Google services, including Google Maps, Google Assistant, and Google Play2. Android Automotive allows for more advanced control of the vehicle's settings, such as the air conditioning system, audio functions, and door locks4. It can also run third-party apps and is not dependent on a smartphone to operate.
As of mid-2024, less than 50 vehicles currently run Android Automotive, according to Google's documentation6.
