In the Model S and X, Tesla uses two different MCUs (Main Computer Unit). This test checks which hardware is in your vehicle when run from the vehicle’s browser.

- Platform indicates the MCU processor, the Nvidia Tegra 3 (arm) in MCU1, and Intel Atom E8000 series CPU (x86_64) in MCU2. MCU2 started shipping in all Tesla S/X manufactured at the start of March 2018.
- UserAgent relates to the hardware and browser software in use. The browser was upgraded in version 2018.14 for MCU1. Expected values were collected in April 2018
- This utility has not been tested with the Model 3 yet and the display value may not be accurate.
- Display width is the browser width, while the height is the display height.
What’s New in MCU2
- Faster CPU, results in snapper operation
- WiFi Support for 5 GHz band
- External Bluetooth Antenna (perhaps for future feature – using a phone as a key like M3)
