Tesla has shown off what may be part of Tesla's v11 software. This morning Tesla posted a video to weibo.cn that shows off new features that will be available in China as part of the 20214.5 release.
Tesla highlights three major new features that will be available in the Chinese market. However, they may not necessarily be available to everyone outside of China. For example, we don't believe the updates to QQ Music would be available outside of China, much like some entertainment apps that are exclusive to certain markets.
TikTok
The first major feature that Tesla shows off is the addition of the entertainment app TikTok. The app will be added alongside the other apps currently available in the market and maintains the features popular in the mobile app such as 'Following' and 'For You' tabs, the ability to favorite and view comments on the videos. Although it's unclear whether they will allow you to comment on videos.
The layout of the app is particularly interesting as the design appears to take a cue from the Model S/X redesign videos we've seen recently where there is a black navigation bar on the left side.
QQ Music Lyrics
The second feature the video goes into is QQ Music. QQ Music is a streaming service in China and it has been available since 2019 on Tesla vehicles. With this update they're adding karaoke-like support to the service where users will be able to view song lyrics as the song plays in a very similar fashion to Caraoke.
Improved Voice Recognition
Speech recognition improvements are being highlighted as much improved in 2021.4.5 as well. The voice commands in the vehicle are great but you often have to phrase them in a very specific way to get them to work. It looks like Tesla has tried to improve their understanding of commands in this release.
In the video Tesla shows examples of a driver issuing commands like navigate to, calling someone or playing songs but in various new ways. It's not clear whether these improvements are specific to Mandarin Chinese or will be available more widely.
As Tesla is showing off the new commands and particularly the call command, we can see a slightly new call interface. When calling someone through the voice interface, it appears that the call will be automatically placed after a certain time. A progress bar "count down" will appear on top and a 'Cancel' button at the top giving the user a chance to cancel the command before the call is automatically dialed.
Tesla shows off these three major features as part of 2021.4.5, but there may be other improvements as well. These features are targeted specifically targeted the Chinese market and would not include other features that be only be available in the U.S. or other markets.
The full video is below for those interested in watching.
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.
