Tesla Holiday Update coming soon. Here's what may be included

By Nuno Cristovao

Tesla has historically had a major release almost every year. Some years they release a holiday update that contains exciting new features. Previous holiday updates have included a new user interface, new games, Boombox, Tesla theater and more.

It's an exciting time of the holiday for most people and Tesla is giving us a little extra to look forward to.

Last year Tesla had a holiday update, but ran into several issues and ended up splitting the holiday update into two parts. The first part was version 2020.48.25 and it was released on December 24th.

The holiday update included new games such as Cat Quest, The Battle of Polytopia and Solitaire. Tesla also refreshed the UI, made car visualizations larger and moved the wipers and rear camera buttons to the main navigation bar.

Although some owners weren't a fan of the larger visualization area because it reduced the width available for other apps like music and the web browser, it did give Tesla room to display more visualizations. The visualizations in FSD play an important role in helping the driver understand what the car can see and react to.

On Christmas day Tesla continued the holiday update and released another update, 2020.48.26, which included the Boombox feature.

Unfortunately, part two of the holiday update never officially came. Speculation is that Tesla became swamped with the new Model S software and ran out of time to develop part two of the holiday update.

It's likely that some of the updates that were slated for part two of the holiday update were released separately throughout the year.

Features such as Waypoints, which was recently released in 2021.40.5 could likely have been part of the holiday update. The TIDAL streaming service, Disney+, Car Wash Mode, the ability to disable mirror auto dimming and hotspot support all sound very much like they could have been part of the holiday update.

Unfortunately, Tesla never announced whether these features were originally part of the holiday update or why they weren't released in December of 2020.

Holiday Update 2021

Elon has now said on Twitter that Tesla is planning another holiday update this year, but doesn't give any details on what's in it. Sure, lots of us may be bitter because part two of the last holiday update never officially happened, but it's good to know Tesla is planning for new features this month.

Elon tweeted that the next holiday update is "Coming soon. Lot of cool stuff." Although this message leaves a lot to the imagination, it's fun to speculate what could be included in this update.

We took a look through our Upcoming Features section, which lists every feature that Elon has commented on and we put together a list of possible features that could be included in this year's holiday update.

Share Car through Tesla App

The share your car feature was recently discovered in the new Tesla app's source code. The feature will allow you to share access to your car with someone else for a specified time. Think of it as sharing virtual car keys, complete with an expiration date. Find out how sharing car access will work.

Vehicle Sync

Vehicle Sync will allow you to share your Tesla settings with other Teslas you own or rent. Vehicle Sync will automatically set your preferences such as stopping mode, auto high beams, temperature units and more automatically when you get into a new Tesla. Read more about how Vehicle Sync will work.

Improved Parking Chimes

This feature was recommended to Elon on Twitter and Elon responded and seemed quite fond of the idea. The feature would greatly improve the usefulness of Tesla's parking chime alerts. Instead of the parking sensors generating a generic beeping sound, the volume and direction of the sound would be based on the proximity and location of the object to the parking sensors. So if you were backing up in your Tesla and approaching an object such as a parking lot light pole, you'd hear the parking chime coming from the rear speakers. The closer you would get to the object, the louder the alert would be. Find out more details on the improved parking chimes idea.

Auto Shift

The new Model S and Model X support Auto Shift, which lets your car automatically shift into forward or reverse when coming out of park. Elon has said previously that Auto Shift will not be limited to the new Model S and X, but will also be come to the Model 3 and Model Y. Find out more about Auto Shift coming to other models.

Passenger Seat Presets

Similar to how there are driver profiles that save a driver's preferences, passenger presets would save a passenger's preferences such as seat position and possibly merge the driver's favorite music stations with the passenger's favorites. Read more about passenger seat presets.

Face Recognition

Tesla filed a patent that would use face recognition to set driver profiles. Instead of setting your driver or passenger profile based on which phone was closest to the car, or having to manually select your profile, Tesla could offer simple face recognition that would automatically set your profile for you. This will make a lot more sense when Tesla introduces passenger profiles, as Tesla would likely want to avoid cluttering up the UI with driver and passenger profile buttons. Find out more about face recognition in Teslas.

Apple Music

After Waypoints, this is the most asked for feature in a Tesla. Tesla recently released TIDAL and in the past Tesla has had source code that hinted at additional music services, such as Apple Music. The truth about music services is that the trend will continue and if Tesla adds Apple Music today, then users will ask for Panda, Amazon Music or SiriusXM streaming capabilities. Tesla is full of talented engineers. They're hopefully working on a solution that will generalize music streaming in a Tesla and make it easier to add additional music services. Adding Apple Music capability to Teslas could be 'The Gift' many are hoping for this holiday season. Find out more about Tesla adding additional music services such as Apple Music.

Render Teslas on Display

The ability to identify and display other Teslas on the screen could be just the kind of feature Tesla would incorporate into a holiday update. With the advancements Tesla has made in object recognition, Tesla can pull this off if they choose to. Read more about displaying Teslas on the screen.

Some of these features may show up in this year's holiday update, but like Santa, Tesla always has some surprises up their sleeve as well.

Last year Tesla released the holiday update close to Christmas and since Tesla does staggered roll outs, some owners did not receive the update until after the holidays.

Who knows exatly what's in store for us this year, but we're getting close and it's possible we may see the first sign of this year's holiday update soon. Check out our Upcoming Features section to read about all the features that Tesla may be looking into developing.

Update: We now have more information on the upcoming Holiday Update that may arrive as soon as Tuesday and possibly feature a 'Dancing Mode' for the Model 3 and Model Y.

Update 2: It's confirmed that a Light Show feature is coming to not only the Model 3 and Model Y, but also the Model S. You can view all the known Holiday Update features here.

Update 3: Tesla released many new features in the 2021 Holiday Update. The holiday update was released with version 2021.44.25.

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

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.
