While Tesla showed off a fantastic list of upcoming features for the 2024 Holiday Update, several things were left out. Now that the update has started rolling out in small numbers to the public, it’s our chance to find out about some of these smaller features and view others in action for the first time.

All of these features are part of software update 2024.44.25.2.

Energy App Changes

@g3st4l1

The Energy app has been updated for all models. For the first time, the Model S, Model X, and Cybertruck receive the Consumption tab, which shows real-time energy usage and how the car performed over a certain period. Previously, only the Drive and Park tabs were available.

The consumption tab was already available on the Model 3 and Model Y, but it’s receiving some changes. The Y-axis (energy used/gained) now appears to adjust based on the data; however, the X-axis (distance) is now fixed at 200 miles or 300 km, and the user can no longer change it. Previously, you could switch the graph between a 5-, 10-, and 15-mile history, but now it appears to be static at 200 miles.

The Energy app also included buttons to view your average range over the selected distance or your real-time range. However, those buttons have been removed, and you can now only view your average range at the top of the app and see how it compares to the rated (EPA) range. You can also view your projected range (the distance you can travel at this rate), which shows up in the middle of the graph.

In addition to those metrics, the app also shows you the total amount of energy used in the bottom left corner, which is a nice addition.

The addition of the consumption tab to the Model S, X, and Cybertruck is great, but some users may not be fans of the simplified look and controls. Not being able to select the distance or see the instant energy usage is a little bit of a disappointment. We would’ve loved to see the ability to pinch in and out of the graph so that you can adjust the time period to practically anything you wanted, up to a maximum of the last 200 miles, but overall these are nice improvements.

Unfortunately, this does not bring the Energy app to legacy Model S and Model X vehicles.

Weather At Destination

As part of the Holiday Update, Tesla is including a new feature to show the weather at your arrival destination. Tesla added the ability to view live weather and weather forecasts in the 2024.26 update, and now they’re extending it so that you can also view the weather at your destination.

The UI is intuitive, and tabs are simply added so that you can switch between the weather at your current location and your destination.

Tesla will also highlight any significant weather differences between your current location and final destination.

This feature is available for the Model 3, Model Y, Cybertruck, and new Model S and Model X. It also includes Intel-based vehicles (MCU 2), but like the original weather feature, it requires Premium Connectivity.

Precipitation Map

Another big part of the Holiday Update is precipitation maps appearing as overlays on your vehicle map. When you tap the new precipitation icon on the right next to the satellite imagery button, a precipitation map overlay will appear, giving you insight into areas with incoming rain or snow. There is also an animated 3-hour forecast that shows weather patterns.

This particular portion of the Weather update requires an AMD (MCU 3) vehicle. Unfortunately, since Tesla is paying for this weather data, it’s only available if you have Premium Connectivity and using a hotspot or being on WiFi is not enough to enable the feature.

It’s available on all vehicles except the legacy Model S and Model X.

Boomerang Fu

@g3st4l1

The new Boomerang Fu game will let you slice and dice your friends in a frantic physics party game. The game is available in Arcade > Boomerang Fu, and must be downloaded before being played. If you have Premium Connectivity, you’ll be able to download it on the go.

The game can be played by up to four people, but it does require a controller.

This new game requires an AMD Ryzen-based (MCU 3) vehicle and it’s available on the new Model S, new Model X, Model 3, Model Y and Cybertruck.

Light Show Improvements

Tesla has really hit it out of the park with Light Show Improvements in the 2024 Holiday Update. The biggest change is the ability to start Light Shows directly from your mobile app (V4.39.5+), but there’s more. Tesla has added two new built-in Light Shows based on Cyber Symphony by Lionel Yu and Ready for Assault by Evgeny Bardyuzha.

Tesla is already adding the ability to control interior lighting for Light Shows by adding special color effects, which is sure to make Light Shows even more spectacular. Tesla has also extended the maximum allowed length of a Light Show with this update.

You can check out the music for Ready for Assault below.

Theater Updates

Theatre mode can now be interacted with via the rear screen on vehicles that have them, including the ability to edit playlists or play and pause videos. 

But here’s the most surprising feature in the update. You’ll also be able to start a video in the web browser before you start driving and it’ll continue to play when you shift into drive only. The video will be disabled, but the audio will continue to play. So you’ll now be able to listen to YouTube-only podcasts.

Tesla is also giving us the ability to control the video with the media player, so you’ll be able to pause or start the content while driving.

Dashcam Viewer & Sentry Mode Improvements

@g3st4l1

The Holiday update is packed with features, but one of the most useful will be the ability to view your dashcam and Sentry Mode videos directly from your phone.

You’ll be able to access all of the content on your USB drive from your phone. The vehicle will stream the video from your USB drive, so the vehicle will need an active WiFi or cellular connection in order for the feature to work.

You’ll be able to change cameras, jump to Sentry Mode alerts, and even save clips onto your phone, making it much easier to save that important data.

Sentry Mode Improvements

Sentry Mode also received a batch of improvements. Tesla already sends mobile notifications for critical events - like an alarm going off. Now, Tesla will notify you if Sentry Mode is active and a door handle is pulled on a Model 3 or Model Y. In addition, if someone attempts to open the trunk by pressing the button - or open the Cybertruck’s vault - you’ll get a notification for that too.

Tesla LFP Batteries Can Now Be Warmed up While Supercharging Using Innovative Feature

By Karan Singh
Not a Tesla App

Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.

LFP Battery Heating

Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.

The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.

Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).

In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.

We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.

Tesla Included FSD V12.6.1 and V13.2.4 in the Same Update: What Caused This and What It Means

By Karan Singh
Not a Tesla App

Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.

FSD V13.2.4

A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.

While this update focuses on bug fixes, Tesla’s already working on bigger features for FSD V13.3, which we have already confirmed to include improvements to highway following and speed control.

FSD V12.6.1

FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.

While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.

It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.

Same Update, Multiple FSD Builds

What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.

The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.

While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.

What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.

While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.

While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.

Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
