Tesla recently started rolling out an update that enabled the cabin radar in recent Model Ys and added support for first-row cabin sensing. This functionality not only lets Tesla replace the seat occupancy sensors in the front seats but also gives them a better idea of the size of the passengers — critical information when an accident occurs.
However, Tesla has now revealed that it won’t just be recent versions of Model Y that will receive these updates. Other recent vehicles also have a dormant in-cabin radar that will be activated in a future update.
Child Presence Detection
This front-row occupant sensing is only half of the update. Tesla also plans to add support to the rear seats that will let it detect occupants left in the vehicle. In a post on X, Tesla stated that at least 37 children die per year from heatstroke, just in the United States, according to the NHTSA. Tesla’s cabin radar will help reduce the number of deaths by detecting children left in the vehicle and alerting the owner or turning on the HVAC system.
The new radar has several safety-focused features, and they’re all designed to help protect someone left behind in a vehicle. First up - the radar will detect and classify passenger sizes to determine which airbags to deploy dynamically, helping to reduce injuries from shorter individuals sitting up front.
Additionally, the radar can differentiate an adult from a child or baby - and automatically and dynamically make the necessary safety adjustments on the fly. Tesla will also be able to detect heart rate and breathing through the radar - and has a series of safety steps it can take from here.
If a child or baby is detected being left behind in the vehicle, the Tesla app will immediately notify you and turn on the HVAC system to ensure their safety. In the case of an emergency, the vehicle will automatically call emergency services and report its location.
As a reminder, while Tesla vehicles outside of the United States support eCall, vehicles within the US cannot call 911 unless a phone is connected to the vehicle via Bluetooth. We hope that Tesla looks to add similar capabilities in North America to improve safety capabilities.
Supported Models
Although the cabin radar has only been activated in Model Ys produced in the last couple of years, Tesla said in their post on X that the radar is also available in recent Model 3s and the Cybertruck.
We did a little digging and confirmed that the part numbers for the cabin radar are the same for the 2024+ Model Y, 2024+ (new) Model 3, and the Cybertruck. So, these vehicles should also receive the latest cabin radar features.
Although the 2023 Model Y features a different part number, 2022 and 2023 Model Ys have also been receiving the front-row cabin sensing feature in Tesla’s 2025.2.6 update, but it is less clear whether they’ll receive the rear seats update later this year. The Model S and Model X also include a cabin radar, but the part number also differs from the cabin radar for the 2024 Model 3 and Model Y.
While the new Model Y isn’t available to check against on Tesla’s Electronic Parts Catalog, it looks like Tesla has been shipping the new 4D cabin radar in at least the 2024+ versions of their Model 3, Model Y and Cybertruck.
We expect rear-seat sensing to arrive on vehicles with the latest cabin radar later this year, while it’s unclear whether the other vehicles with the older cabin radar will receive it.
Tesla mentioned that rear-seat support will arrive in Q3 2025 for the refreshed Model Y. Based on the different interior sizes and spaces, sensor calibration and testing for other models may come slightly later.
There has been extensive reporting on what the long-anticipated affordable EV option would become, and we’ve seen numerous news stories mentioning that it was delayed or even arriving on time. The executive team revealed the near-term and long-term plans for Tesla’s upcoming vehicles, and there’s definitely good news to share here.
Updated Timeline
The most important piece of news is that despite all the talk of delays from supposed inside sources, Tesla has confirmed that the plan for its more affordable model remains on schedule for production to begin in the first half of 2025. Tesla’s executive team narrowed that timeline down further - and said that they expect production to kick off as soon as June and that the new model will be in the market shortly thereafter.
While the production timeline itself is on track, Tesla did note that the subsequent ramping process will likely be slower than initially hoped, citing global tariff and financial impacts as challenges to overcome to prepare its production lines.
Hybrid Production Approach
Tesla has once again confirmed that this will not be their next-generation vehicle, built using new production methods. Instead, they outlined a relatively more pragmatic approach for this new model.
Tesla will utilize aspects of both the next-generation platform as well as some parts of its current platforms (namely the Model 3 and Model Y). This means that Tesla will produce this new vehicle on the same manufacturing lines as the Model 3 and Model Y.
This strategy allows Tesla to bring the vehicle to the market more quickly, while also managing capital expenditures more efficiently by using existing infrastructure. However, Tesla’s executive team also noted that this approach, while faster, will result in fewer cost reductions than what might have been achieved with an entirely new platform and dedicated manufacturing process.
Vehicle Design
Using these existing production lines means that Tesla’s new vehicle will likely share some considerable similarities with either the existing Model 3 or Model Y. Rather than being a radically different and smaller vehicle, this new model will resemble the overall form factor and shape of Tesla’s current core offerings, while being optimized for a lower cost.
This doesn’t mean that Tesla is forgetting the overall goal here. Their ultimate goal is to reduce the initial cost of ownership and lower monthly payments for customers while maintaining a standard of excellence and safety.
Not Unboxed
Both at this Earnings Call and previous ones, Tesla has indicated that this new vehicle will not be using the innovative unboxed assembly method, at least for the time being. That relatively unique method will be developed and implemented specifically for the purpose-built Cybercab and for future vehicles on the next-generation platform.
We’re just a few days away from May, so it won’t be long before we see more about this upcoming vehicle. Stay tuned.
In a follow-up move to the current US administration’s goals to introduce a federal framework for autonomous vehicles, the US Department of Transportation (USDOT) is loosening autonomy restrictions following an announcement from Secretary Sean Duffy on X. This new initiative helps streamline complex regulatory processes and foster home-grown innovation.
From the Wright Brothers to the first astronauts on the moon, our nation has always been at the forefront of transportation technology.
That’s why today we're unveiling a new Automated Vehicle Framework from @USDOT’s Innovation Agenda ⬇️ ⬇️ pic.twitter.com/W3kbMUwQSn
As part of the broader upcoming USDOT Innovation Agenda, the newly unveiled AV Framework is designed to promote American innovation and strengthen domestic engineering while maintaining existing safety standards. The framework centers around three key principles:
Prioritize Safety
Unleash Innovation
Enable Commercial Deployment
To kickstart this AV framework, USDOT announced two initial steps focused on streamlining processes and expanding opportunities.
Crash Reporting Requirements
Under the first principle to Prioritize Safety, the National Highway Traffic and Safety Administration (NHTSA) will maintain its Standing General Order requiring crash reporting on Advanced and Automated Driver Assistance Systems (ADAS and ADS).
However, the reporting process will be streamlined following feedback from AV innovators, likely including Tesla. The goal here is to focus on collecting critical safety information while removing unnecessary or duplicative items from the reporting process, thereby reducing the burden without compromising safety.
Cutting Red Tape
Directly tied to the second principle of Unleash Innovation, the framework also seeks to slash red tape. The first step here is the expansion of the Automated Vehicle Exemption Program, or AVEP. This program allows manufacturers to petition for temporary exemptions from certain federal motor vehicle safety standards (FMVSS) for testing or deployment purposes.
Previously, the standard excluded domestically produced vehicles. Now, domestically produced AVs will not need to meet FMVSS, which will broaden the scope for manufacturers to test more innovative and unique designs and technologies.
Single National Standard for AVs
Finally, tied to the third principle of Enable Commerical Development, USDOT intends to move the United States closer to a single national standard for autonomous vehicles. This aims to prevent a confusing and inefficient patchwork of state-level or city-level laws and regulations, which can create hurdles for companies attempting to innovate, deploy, and scale their technology.
A unified standard across the United States also means that Canada and Mexico will likely be able to follow, as they share homologization standards across North America, including for vehicle crash safety and some autonomy regulations.
What This Means for Tesla
These framework changes will likely have a substantial impact on Tesla. The move towards a national standard is potentially the most impactful change, as Tesla identified regulatory hurdles as one of the most significant challenges it will face with the deployment of both Unsupervised FSD and its Robotaxi network.
The reduction of FMVSS requirements and streamlined reporting will likely play a role in the future as well. The FMVSS requirements are probably already being worked on, if not already met, by the Cybercab and other vehicles in Tesla’s lineup.
Meanwhile, the streamlined reporting will be helpful once Tesla officially launches its Robotaxi network in June.
