Tesla hacker @greentheonly has uncovered details about a new hardware version for the Model Y, labeled as “Model Y Reloaded” in internal markings. He frequently obtains Tesla computers either from salvaged cars and other means, for deep dives.
This updated hardware appears to be designed as a retrofit option for existing Model Y vehicles equipped with HW4 (Hardware 4), offering new features and enhancements.
Key Features of “Model Y Reloaded”? Unlike current HW4 computers, this version includes a connector for a front bumper camera, suggesting Tesla is preparing to introduce this feature for retrofitted vehicles.
Also, the modem is now built into the hardware rather than located in a separate Telematics Control Unit (TCU), streamlining the setup. The hardware uses USB 3.0 ports instead of USB-C, reflecting compatibility with older systems in existing vehicles.
Marked as a service replacement unit, this hardware is clearly intended for use in updating existing Model Y vehicles rather than for new production models.
@greentheonly confirmed that the hardware is designed for retrofitting existing HW4-equipped Model Y vehicles, not older HW3 setups, as it uses connectors compatible with newer cameras and wiring.
Tesla has also removed previous HW4 versions for the Model Y from its electronic catalog, signaling that “Reloaded” could replace older units entirely.
The new Model Y that launched in China, has a front bumper camera. Existing Model S and Model X hardware already have a front bumper camera connector as well, confirmed green.
Tesla CEO Elon Musk has previously said that the company would pay for retrofits for HW3 cars to HW4, if Full Self-Driving (FSD) Unsupervised cannot be achieved on HW3. This only applies to those that paid for FSD.
