Tesla's Track Mode gives the driver even more control over their vehicle by giving them the ability to adjust various settings.

The driver can adjust the handling, traction control, and regenerative braking of the vehicle. These settings can improve the handling and acceleration of the vehicle when turning corners.
With Track Mode drivers can also modify the balance of the car to favor a full rear-wheel-drive layout.
In addition to being able to adjust these settings, Track Mode also shows additional visualizations. For example, there’s a g-force graph that allows the driver to see the amount of g-force when turning corners, and you can also see the temperature of the tires, motors and the battery pack.

Until now, only Performance or Plaid models have been able to take advantage of Track Mode, but this could soon change.
Track Mode was originally designed and calibrated for the Performance Model 3 which is equipped with performance brakes and tires. It is still not available for the Performance Model Y despite being announced last July. With the recent software update 2021.44.30, Tesla rolled out Track Mode to the Model S Plaid, so it’s possible the Model Y may be next.
In addition to customizing how the vehicle handles, the increased performance cooling, and the visualizations, Track Mode also includes some additional features.
Track Mode will let you set start and finish markers on the map. When these markers are set, the car will automatically display lap timings and record each lap through the car's cameras.
The cameras used during track mode are the same ones that are available when using the Dashcam. However, when using Track Mode, the car will automatically save each lap as a separate video to your USB drive.
According to Elon, we will see Track Mode become available for non-performance versions of the Model 3 and Model Y.
In a recent Twitter conversation between @_bennettm and Tesla CEO, Elon Musk, it was revealed that Track Mode will be available for non-performance models. When asked if Model 3/Y owners with Acceleration Boost upgrade could get Track Mode, Musk responded "Ok".
While Track Mode is said to come to non-Performance models with the Acceleration Boost upgrade, it may soon be available in some capacity for all models. Over-the-air performance upgrades are nothing new for the automaker. Tesla launched a $2,000 Acceleration Boost upgrade for some select vehicles last year.

Owners with Acceleration Boost, and maybe even those without it can expect Track Mode to become available in a software update in the near future. It's also a good possibility that Tesla may release Track Mode for the Model Y at the same time.
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.
