Tesla’s refreshed Model Y is currently being manufactured as Tesla prepares for its first deliveries next month. While we’ve already seen quite a few cool new features, there’s more that has yet to be revealed. A recent video interview with Tesla’s engineering team hosted by Tesla Owners Silicon Valley reveals that the vehicle includes a new 4D cabin radar.
4D Radar
While Tesla has included an in-cabin radar since 2022, this appears to be a new, more capable radar. The current cabin radar is used to verify seat occupancy, but Tesla plans to add more functionality to this new system.
This updated radar will be used to provide a lot more detail than the current radar or cabin camera can provide today. The radar is located in the same location as the current version, directly above the rearview mirror.
Classify Passenger Size
This new radar has several new safety-focused features, and they’re all quite exceptional. First off, the radar will detect and classify passenger size to determine which airbags to deploy dynamically. That means that if a shorter individual is sitting up front, the dashboard airbag may not activate - but the curtain airbag will.
That will reduce injuries in impacts from airbag activation while also reducing repair costs by not activating unnecessary airbags. By having a better idea of the passenger’s size, height, and weight, the vehicle can also better determine when to activate the airbag.
Children Left in Car
But that’s not all - because of that classification system, the radar can differentiate an adult passenger from a baby or child sitting in the second row - and automatically make the necessary dynamic safety adjustments.
The cabin radar will also detect heart rate and breathing, and Tesla will automatically send a reminder through the Tesla app if it detects a child is left unattended in the vehicle. If this occurs, the vehicle will perform a variety of functions, the first being to turn on the HVAC system and send you a reminder. And if that’s not enough - in the case of an emergency, your vehicle will automatically call emergency services for you and report its location.
It’s important to note that while vehicles outside North America have eCall capabilities, in North America, they cannot call 911 unless a phone is connected to the vehicle via Bluetooth. We hope that Tesla can contact 911 via an alternative method or add eCall capabilities to these vehicles.
In late 2023, Tesla added the ability for the vehicle to call 911 over Bluetooth when the vehicle is involved in a crash.
Coming Soon
While the refreshed Model Y will be shipping in March, this new radar and its associated features won’t be available immediately. Tesla intends to activate these new safety features in Q3 2025 - so sometime in late summer or early fall. We’ll dive into this new feature once it’s available later this year.
