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.

Winter is here, and temperatures are dropping, so one of the most common Tesla questions is about to resurface.
If you’ve landed here after frantically searching about “smoke” coming from your Tesla while Supercharging, take a deep breath—it’s completely normal.
Tesla Smoking While Charging
If you’re Supercharging in freezing weather—even with preconditioning—you might notice steam rising from your Tesla. But rest assured, your car isn’t smoking.
Your Tesla’s heat pump is hard at work warming both the cabin and battery to keep you comfortable and ensure optimal charging temperatures. Over time, condensation and ice build-up in the heat exchanger coils.
Why Does It Happen?
When you reach a Supercharger with your vehicle, the heat pump is still running hot, but without the cold air from driving to keep the heat exchanger coils cool, the ice and condensation quickly start to evaporate—creating what looks like smoke.
Since this typically happens near the front of the vehicle, where a car would traditionally have an engine, new vehicle owners can be startled by the discovery. However, rest assured that it’s just water vapor and it’s completely normal in cold weather.
In fact, this behavior can be experienced in any EV with a heat pump in cold climates. So, if you saw steam coming out of your vehicle and panicked, don’t worry—you’re not alone.
Now that you know what’s happening, go ahead and Supercharge with confidence.
Tesla made a lot of improvements in the 2024 Holiday Update, including more than 15 undocumented improvements that were included in the release. One of these was a stealthy performance improvement to the YouTube app.
Several people have mentioned they’ve seen improved performance on YouTube since this year’s Holiday Update - and there’s an interesting reason why.
YouTube Improvements
The improved YouTube performance in Tesla vehicles comes from an unexpected source—Tesla actually rolled back support for YouTube’s newer AV1 video encoding. Instead, vehicles now default to the older VP9 encoding standard.
While AV1 is highly efficient in terms of bandwidth, it requires considerably more processing power to decode and display videos. VP9, on the other hand, is less computationally demanding but uses more bandwidth to achieve the same video quality. This trade-off means smoother playback and better overall performance, even if it comes at the cost of slightly higher data usage.
Intel Inside
The VP9 video codec that the YouTube app is now using is much easier to decode, making it less taxing on the vehicle’s processor. This change is particularly beneficial for Tesla vehicles with Intel processors, which previously struggled to stream video at just 720p. When using AV1, these vehicles often experienced stuttering, sometimes forcing the YouTube app to automatically downgrade playback to 480p.
With this update, Intel-based Teslas should now be able to stream at 1080p smoothly. Streaming at 1440p is also possible, although occasional stutters still occur as the system keeps up with the decoding process.
Intel-based vehicles are the big winners with this change, but this appears to affect AMD Ryzen-based infotainment units as well, providing even smoother playback.
Chromium Web App
Tesla’s Theater apps aren’t native applications; instead, they run as chromeless web apps, leveraging the open-source browser built into Teslas known as Chromium (the open-source version of Chrome). Although this works quite well, there is a severe limitation - Chromium hardware acceleration isn’t supported on Linux, the operating system Tesla uses for their OS.
As a result, Tesla vehicles rely on software decoding instead of hardware decoding, which would otherwise handle video playback far more efficiently. A potential solution could be for Tesla to transition away from Chromium-based web apps in favor of a Mozilla Firefox-based browser, as Firefox does support hardware acceleration on Linux. This switch could also open the door to better streaming performance and the possibility of expanding Tesla’s in-car entertainment options.
However, Tesla’s choice of Chromium likely stems from Digital Rights Management (DRM) requirements for streaming services like Disney+ and Netflix, which rely on DRM-enabled playback. Firefox on Linux has had inconsistent support for DRM due to codec availability and variations in operating system versions.
We’re hopeful that Tesla will either adopt Firefox or develop a fully native application to improve video streaming, rather than continuing with the current web-based Tesla Theater. This shift could also pave the way for additional in-car applications built on Tesla’s native Linux environment—perhaps even reviving the long-rumored Tesla App Store.
Regardless, this update is a welcome improvement, particularly for YouTube, which remains one of the most widely used Theater Mode apps due to its accessibility, free content, and mix of short and long-form videos. It remains to be seen whether similar improvements are made for Netflix, Disney+, or other streaming platforms.
If you’ve noticed improved performance in Theater Mode, now you know why.
