An updated yoke is coming to the Model S and Model X, along with ambient lighting and more
Not a Tesla App
Tesla appears to be ready to unveil some changes to the Model S and Model X.
The Model S and Model X will gain updated "efficiency" packages in 2024. References to these hardware changes were spotted by Tesla enthusiast Greentheonly in the 2023.44.30.8 vehicle firmware. Green goes on to say that Tesla makes efficiency package changes when there are changes to the battery or drivetrain that affect the vehicle's range.
However, these changes don't necessarily mean the changes will improve efficiency or increase the vehicle's range.
Former Tesla service technician, Anthony Spina mentions that Tesla last changed an efficiency package in 2021 when they increased the battery pack for the Model 3 and Model Y from a 77 kWh battery to a 82 kWh battery. Tesla also added more efficient motors at the time.
Tesla recently updated their EPA mileage for new models in the U.S. and Canada due to government-required testing changes. Although vehicle hardware didn't change, the EPA estimates are now lower than before across most Tesla models, including other EVs.
This is because the EPA now requires vehicle manufacturers to account for all acceleration modes and averaging them when determining the vehicle's range.
To combat less efficient stopping modes, Tesla is removing roll and creep modes on new Model 3 and Model Ys in these countries.
Update: New Model Xs have now come off the assembly line with the new steering wheel we talk about in this article, although they do not include additional changes to the battery pack, drivetrain or the ambient lighting and front bumper camera changes. It appears that Green’s findings for the new efficiency package in the vehicle’s firmware may have been related to Tesla’s updated EPA range estimates and not related to changes to the battery pack or drivetrain themselves, as they have been in the past.
However, the new Model S and Model X are still expected to receive the ambient lighting treatment akin to the new Model 3 and the front bumper camera like the Cybertruck.
Center Horn
While looking through the firmware's code, Green also found a reference to a new yoke for the Model S and Model X. The new wheel will finally feature a mechanical horn in the center. Since the new Model S was revealed in 2021, it has used a small button on the steering wheel to activate the vehicle's horn.
We've heard that this center horn has been coming for a while now, but given that it's now showing up in Tesla's firmware, it looks like a release may finally be near.
Ambient Lighting and Bumper Camera Also Coming
The Model S is due for a new seat design. A few months ago, the parts catalog displayed a different seat design with a much higher and more narrow headrest. Directly below the headrest is a Plaid badge that looks like it could be swapped out for different designs. The seat design is similar to the RECARO or Sparco racing seats, two leaders in the performance automotive seat field.
The ambient lighting in the new Model 3, and Cybertruck has been a popular feature, adding an option to the vehicle's cabin that resonates with the high-tech feel of these vehicles. The ambient lighting addition is certainly coming to other models, and our source previously confirmed that it will include the Model S and Model X. Remember the Model Y refresh, code name Juniper is underway.
The front camera is also featured in the Cybertruck and will undoubtedly be added to the rest of the fleet. The camera removes the blind spot just in front of the car for those tight parking spaces and has been a welcome addition after removing other sensors. Our source also confirmed that the front bumper camera will also be arriving on the Model S and X.
However, all of these changes may not necessarily arrive at the same time. Tesla is all about efficiency and doesn’t roll out changes with model years, so they will typically only add new parts when they’ve used up their current supply. We could see the bumper camera arrive first and later followed by ambient lighting, although we wouldn’t expect these features to be very far apart.
It’s the start of a new year, but the same ol’Tesla, a company that continues to make changes, adapting to new testing and customer preferences.

Tesla has released software update 2025.2.6, and while minor updates typically focus on bug fixes, this one introduces a major new feature. With this update, Tesla has activated the in-cabin radar, a sensor that has been included in some vehicles for more than three years but remained unused until now.
Why Not Vision?
Unlike vision-based systems, radar can precisely measure object dimensions and even detect movement behind obstacles by bouncing radio waves off surrounding surfaces. This allows for more accurate and reliable measurements of objects that vision may not even be able to see, such as behind the front seats.
What Tesla Announced
Tesla recently highlighted the 4D radar in the new Model Y, explaining how it will improve passenger safety. Tesla executives stated that the radar would be used to properly classify passengers and improve the way airbags deploy.
Tesla went on to say that in a future update, Tesla will use the in-cabin radar to detect any potential passengers left in the vehicles. Since radar can even pick up on heartbeat and breathing patterns, it can provide a much more accurate method of detecting children left in a vehicle. Tesla talked about how the vehicle will send owners a notification via the Tesla app and enable the HVAC system if it detects a passenger in the vehicle. It’ll even call emergency services if needed.
New Feature in Update 2025.2.6
Tesla has officially named this feature in update 2025.2.6, “First-Row Cabin Sensing Update,” which appears to align with the first portion of what Tesla discussed in the new Model Y video.
In the release notes, Tesla describes the update as:
“The first-row cabin sensing system has been updated to use cabin radar, which is now standard in all new 2025 Model Ys. Your Model Y was built pre-equipped with the necessary hardware, allowing Tesla to also bring this technology to your vehicle.”
For now, it appears that Tesla is using the radar to detect and classify passengers in the front seats. This could eventually replace traditional seat sensors, reducing the number of hardware components and lowering production costs.
Tesla plans to expand the feature later this year, bringing rear-seat passenger detection in Q3 2025. While Tesla talked about the feature for the new Model Y, we expect it to be available for all vehicles with the in-cabin radar.
Supported Models
Although Tesla is vague in their release notes, this feature is being added to all Model Ys that include a cabin radar. Tesla started including the cabin radar in 2022, but its availability may vary by region and model. The Model 3 didn’t receive the cabin radar until it was redesigned in 2024, while all Cybertrucks already include it.
The owner’s manual for the redesigned Model S and Model X doesn’t specifically mention the interior radar, although Greentheonly believes the vehicles also include one, so we’ll have to wait to determine whether those vehicles also receive this new feature.
At this time, the feature appears to be only going out to Model Y vehicles, but we expect it to become available on other supported models soon.
We love to see these kinds of updates. Tesla is increasing the safety of existing and new vehicles through a software update while also making them more affordable to own.
Tesla has updated the Tesla app to version 4.42.0, and this time, it’s more than just bug fixes. The app includes a new service interface, introduces support for the new Model Y, and, for the first time, includes some code for the Robotaxi coming later this year.
This update was released for iOS and should be available on Android within a few days.
Refreshed Model Y 3D Model
First up in the update is the introduction of the 3D model for the refreshed Model Y. Interestingly, while we all know it as Juniper, the file code name inside the update lists the vehicle as “Bayberry.” The Bayberry name was introduced in Tesla app update 4.41.5. Tesla’s internal code names sometimes change as the vehicle evolves - and we’ll continue to refer to it as the refreshed or new Model Y for ease of understanding.

As usual with Tesla’s 3D models in the app, there’s a lot of detail, although it’s not easy to see since you can pinch and zoom the model in the app. The 3D models used in the app are actually the same models that Tesla uses in the vehicle, although sometimes they include different lighting effects, but they’re all highly detailed.
Robotaxi API
Tesla has added a new endpoint in their app for Robotaxi - and it’s the very first Robotaxi or Cybercab-related item we’ve seen in the app. With the Robotaxi fleet launching in June, according to Tesla, it looks like they’re now adding support to the Tesla app.
What the Robotaxi interface is supposed to look like in the future.
Not a Tesla App
The new app API is called “rides_feedback_upload,” which seems pretty explanatory. Tesla will need to gather a lot of information on ride quality and all the little things in between. What better way than to get feedback directly from users?
While Tesla previously released prototype images of what the Robotaxi app will look like, the introduction of this API into the Tesla app leads us to believe that Tesla will utilize the current app for Robotaxi use.
Updated Service Interface
The Updated Service Panel in the Tesla App
Not a Tesla App
Tesla has released an updated UI for the Tesla Service panel, and we have a ton of details on these changes. This new pane displays appointment details more prominently. If you have a service appointment scheduled, you’ll now see a lot more details on the main service screen. The app will now display:
Your current service status
Appointment date and time, which you can now tap on to add the event to your calendar
Address and hours of the service center. You can now also tap on the address to open up the location in your maps app
There’s also a new appointment details screen (the right portion of the image). This screen displays additional details that were previously unavailable, such as your transport type. The app will display whether you’ll get a loaner vehicle, demo vehicle, or something else.
There are a ton of user experience (UX) improvements in this update regarding service, including clearer language, improved UI fixes to images, and more.
Tesla has been making a lot of positive updates to the Service-related sections of the app lately, and we’re happy to see these coming rapid-fire. Tesla Service is now easier to use and understand. In the previous app update, Tesla also added the ability to pull down to update the service screens.
