Tesla China has just launched the 2026.14.13 version of the in - vehicle system update, which is applicable to four models: Model 3, Model Y, Model S, and Model X. This update comes with a host of impressive features.

For the first time ever, it incorporates ByteDance's Doubao large - scale model as an in - vehicle intelligent assistant. This assistant is capable of engaging in natural conversations, answering information queries, and offers a variety of voice tones along with exclusive personas. However, to access these functions, users need to have an active subscription to the Premium In - Vehicle Entertainment Service.

A brand - new exclusive pet mode has also been introduced. In this mode, users can personalize their pet's appearance and name. Moreover, the system will automatically regulate the in - car temperature and humidity to create a comfortable environment for the virtual pet.

In terms of interaction enhancements, the trip module has now been integrated into the "Energy" app. This makes it more convenient for users to manage their trip - related information in one place. Additionally, materials created on the in - vehicle sketchpad can be synchronized to mobile phones, allowing for seamless cross - device usage. The playback logic of Apple Music has also been optimized, providing a smoother music - listening experience.

From a security and functionality perspective, the system has addressed three types of underlying vulnerabilities. An automatic nighttime update toggle has been added, giving users more control over when the system updates. Furthermore, dashcam footage can now be permanently stored locally, ensuring that important video evidence is always available. At the same time, the in - vehicle map data package has been upgraded to provide more accurate and up - to - date navigation information.
