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 recently launched software update 2025.8.3, which included a bunch of “minor updates.” Nestled away in the release notes are a couple of interesting features - including some major changes to the Energy App.
We’re not quite sure we’d call these minor updates, so let’s take a bit of an exploration of the revitalized Energy App.
The Energy App has received some new categorization features in the Consumption tab. You can once again limit the graph by distance. As part of the 2024 Holiday Update, Tesla redesigned the consumption tab and brought it to the new Model S and Model X for the first time. However, with the redesign, Tesla removed the ability to choose the distance shown in the graph, instead providing a static display of the last 200 miles (300km).
The first part of the improved Energy App is bringing back this distance filter. You can now choose between showing the last 10, 100, or 200 miles (15, 150, or 300 km). This differs from the previous available distances of 5, 15 and 30 miles, but brings back the ability for the driver to choose a distance that may be more applicable to how they’re driving.
We’d love for Tesla to introduce custom distances by pinching and zooming the graph or simply add the ability to choose “This Drive Only” to the list of available distances.
Reset Energy App History
@EV3_Model3 on X
Sadly, the “Instant Range” button that was available in the Energy App before is still not available, but Tesla introduced a new feature that may be even better. You can now clear your driving history so that the graph only reflects your current driving style.
This is a little hidden, but if you tap the little info icon at the top near your average Wh/mi, you’ll now be presented with a dialog that lets you clear your history.
This could be useful if you’ve just come from some hard driving on a track or off-road, where energy consumption could be exaggerated. It could also be useful if you just started towing or a different type of driving that is drastically different from your current driving.
Other Changes
In addition, it looks like future predictions of the Energy app now take into account your driving history and apply that in addition to expected vehicle consumption, weather, altitude, and the multitude of other factors that your Tesla constantly takes into account while calculating your expected range.
While these are smaller improvements to the Energy app, they added some important functionality, as it helps users better understand their vehicle consumption and display data that is more applicable to the current driving style.
This is a great example of Tesla listening to its customers and bringing back features they had previously been removed. Check out the video below by akide on the updated Energy app in update 2025.8.3.
Sandy Munro once again had the opportunity to chat (video below) with Lars Moravy, Tesla’s Vice President of Vehicle Engineering, as well as Franz Von Holzhausen, Tesla’s Chief of Vehicle Design. This time, rather than focusing on the improvements to the refreshed Model Y and all the new engineering behind it, the focus was on Tesla’s autonomous ambitions.
In this case, the Cybercab and Robovan were the key highlights, with a distinct focus on the Cybercab. With that all said, let’s dig into all the fun new stuff. You can check out the entire video at the end of the article.
Cybercab Unboxed Process
The Cybercab will be the first of Tesla’s vehicles to use their new unboxed assembly process, which builds vehicles in parallel sections, and then brings them together all at once for final assembly. Traditionally, vehicles are assembled from the ground up, and sometimes even disassembled for parts of production to take place.
This innovative method involves using a big rear and front casting, brought together by a structural battery pack on the floor. The door rings are hot-stamped and laser-welded to form the side shell of the Cybercab, resulting in a very rigid structure that can also absorb crash impacts due to its unique manufacturing.
Paint-Free Panels
We’ve already talked about the Cybercab’s unique paint-free panels, but we’ve never heard until now exactly how Tesla intends to manufacture them. Tesla will inject colored PU plastic onto the backside of another plastic part (formed from various processes) and then ultrasonically weld that entire piece to an inner part.
That essentially combines multiple parts into one smooth piece that is easy to repair - because all you have to do is remove the entire panel - it just comes off as the interior fasteners are removed. There is no subframe holding it together - instead, the subframe is part of the panel.
The only area of the vehicle that will have any paint will be the hot-stamped door rings - which will be painted to improve corrosion resistance to protect the steel.
Aerodynamics
Aerodynamically, the Cybercab boasts the largest aero-cover-to-wheel ratio of any Tesla vehicle. This updated aero cover improves efficiency, even with the Cybercab’s relatively large tires—chosen to reduce rolling resistance. Interestingly, the impact of unsprung weight on efficiency is minimal compared to the benefits of improved rolling resistance and aerodynamics.
Another key to the aerodynamics is the teardrop shape of the Cybercab itself. With its low profile and smooth shape, it is extremely aerodynamically efficient. While neither Sandy nor Lars delved into drag coefficients, we expect it will likely be more efficient than the Model 3’s already fantastic Cd of 0.219.
Range and Battery Pack
Tesla currently has prototypes undergoing real-world testing at Giga Texas to evaluate range and efficiency. The goal is to ensure the vehicle can operate throughout an entire day in the city before returning to charge.
Tesla is targeting a battery pack under 50kWh, delivering close to 300 miles of real-world range—an impressive efficiency of around 166Wh/mi, even outperforming the Model 3’s lowest at 181Wh/mi.
When Does It Arrive?
So, with all that new knowledge - when does the Cybercab arrive? Well - the prototypes for the June Robotaxi network deployment in Austin are getting prepared now - but Tesla expects to begin production and sales sometime in the first half of 2026.
