Tesla’s New “Hardware 4” Radar Appears in Parts Catalog

Last year, Tesla began transitioning its fleet to Tesla Vision, the company’s camera-based autopilot system. The decision was controversial and polarizing even among Tesla supporters, as many believed the radar added significant value to Autopilot and FSD. If recent sightings from the Tesla community are any indication, however, it looks like Radar could make a potential return in Hardware 4.

Teslas today are equipped with the company’s Hardware 3 computer, which is already extremely advanced on its own. But while HW3 is already impressive, Tesla is a company that never stands still. Thus, the expectations that Hardware 4 will be rolled out in the near future have been high. Elon Musk has certainly fueled this speculation, noting at last year’s AI Day event that the Cybertruck will be the first Tesla to feature a Hardware 4 unit.

Specifications for Tesla’s Hardware 4 computer have yet to be announced, but it wouldn’t be surprising if the company provided previews of HW4’s capabilities at the upcoming AI Day 2 event later this month. A recent discovery by a famous Tesla hacker @greentheonly, however, suggests that HW4 could use a new radar unit. The new radar unit is teased in Tesla’s online parts catalog, and it’s listed under the 2021 Model X electrical systems.

As noted by hacker Tesla, the new radar unit has no description in the parts catalog, only an illustration. The new radar unit listed in the parts catalog also has a matching radar mount which is different from the previous radar and mount used by the company.

The presence of an apparent new radar in Tesla’s parts catalog is certainly interesting, although it’s by no means a definitive confirmation that radar will make a return. After all, other features that made their way into Tesla’s parts catalog, such as the Model 3’s air suspension, were debunked by Elon Musk himself. That being said, it would be nice if Tesla’s Hardware 4 computer was at least compatible with radar sensors.

Interestingly enough, Elon Musk may have released a teaser of HW4’s potential radar unit earlier this year. In February, Musk was asked on Twitter about his thoughts on people who think radar is still extremely useful. The CEO of Tesla then replied that “Only very high resolution radar is relevant.” It wouldn’t be surprising if Tesla used such a sensor on its vehicles, given the company’s tendency to equip its cars with advanced technologies.
