Tesla's Holiday Update has made the most wonderful time of year the hap-happiest season of all. Adding to the parties for hosting, marshmallows for toasting and caroling out in the snow have been significant advancements to the user interface, the apps and the farts. So, in the spirit of reflection, let's look back at the last five years of updates courtesy of Santa Musk and the Tesla Elves.
2018
The 2018 update was significant because it was the first to go to the Model 3. Yes, it's hard to believe the Model 3 was celebrating its first Christmas five years ago. This update brought the browser, calendar and energy app to the 3, plus much more to the rest of the lineup.
Navigate on Autopilot made its first appearance in Beta. It suggests lane changes and monitors surrounding traffic to make adjustments to ensure you don't get stuck behind slower traffic. Autosteer and Auto Lane Change were also combined in a beta feature. If you were around when these features were first introduced, you know exactly how far they've come. Plus, Blindspot Warning was introduced. You can see how these are now utilized with today's vehicles, combining the technology as the company works towards Full Self Driving.

Another significant advancement in how Tesla operates came with increased regenerative braking. Tesla continues to lead the EV market in regenerative braking, and this update allowed more kinetic energy to return power to the battery.
2019
There was more fun in 2019, with the addition of the Tesla Theater, a new arcade game (Cuphead) and more media options. But, first, carrying over from 2018, yet another piece in the Autopilot collection was unveiled with Smart Summon, allowing users to have their Tesla come to them.

The Theater brought Netflix into Tesla, of course, when in park, so those waiting for their spouse to finish Christmas shopping could sit back and binge-watch their favorite shows. Nothing to watch? Tesla has you covered with Caraoke. This road trip favorite was also launched in 2019 alongside the inclusion of Spotify in the US market.
2020
In 2020, Tesla stuffed three new games down the chimney and into cars worldwide. The games were Cat Quest, the Battle of Polytopia and Solitaire. Is anyone else happy Steam was added in 2022?
While the entertainment addition wasn't at the same level as the previous year, made several UI improvements with driver visualization improvements, scheduled departure upgrades, Boombox and improvements to Emissions Testing Mode and Text messaging.
2021
2021 was a magical year allowing users access to the side camera to act as a blind spot camera. This welcome improvement caught Tesla up to the legacy automakers in that regard. From a usability standpoint, the company made the app launcher customizable and simplified controls so drivers can focus on navigation and primary controls, although there were some UI changes that needed to be gradually rolled back or reworked.
Three more video games were added, Sonic the Hedgehog, The Battle for Polytopia (Multiplayer) and Sudoku. Did I mention I'm happy Steam was introduced in 2022?
Since the update came out in December, its fitting cold weather improvements and automated seat heaters were included. Tesla also introduced the ability for seat heaters to be automated based on the desired cabin temperature. The Car Wash Mode was added, and perhaps one of the most used features, Sentry Mode Live Camera Access.
2022
That brings us to 2022. The year Steam was put inside the newer Model S and Model X cars, giving users the ability to access more than 50,000 high-end, high-resolution games. Apple Music, MyQ garage door opener, and Zoom were also wrapped up and put under the tree.
Tesla's incredibly generous gifting continues to have hearts glowing over the holidays. Just 12 months until the next big update. Let us know what's on your wishlist and be sure to stay on the nice list!
A Look Back at the Model 3's Interface
Take a look at the Model 3's interface and its early reviews back in 2018.
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 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.
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.
