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.

FSD’s insatiable appetite for AI compute is taking shape once again at Giga Texas, where Tesla is building out Cortex 2.0 — its second large-scale GPU supercomputer cluster — on the facility’s north side.
This confirmation comes thanks to the detailed research and findings by Giga Texas drone pilot Joe Tegtmeyer, who shared his findings on X.
For months, there has been some speculation on what this new site would be - new storage, the Optimus production line, preparation for the Cybercab’s unboxed assembly process, and more. Now, thanks to permits filed by Tesla, we know that this new area is destined to become the second supercomputer destined for FSD training.
Cortex 2.0
There are some key details we can unpack from what we’ve learned about Cortex 2.0. The new facility will be on the north side of Giga Texas, opposite Cortex 1.0, which is on the south side. The permits explicitly tie the usage of this expansion to Cortex 2.0, namely through the fact that it is a data center.
This is actually a change from Tesla’s original plans - the northern section was intended to be used as a central campus support facility, with three smaller facilities and water storage tanks. Now, it has been redesignated as Cortex 2.0 and is one large structure.
The permits that have been filed have already been approved and cover the foundations, underground water mains, and building itself. The steel structure is actively being put together on the concrete foundations, and about 50% of the roof decking is already complete, bringing the exterior shell closer to completion.
Fueling FSD’s Brain
The deployment of Cortex 2.0 is the latest in Tesla’s massive and ongoing investment in the computational power required to train FSD. While this primarily covers FSD for cars, this will also eventually apply to Optimus, which is powered by the same AI4 computer and also runs a variant of FSD.
This isn’t Tesla’s first foray into large-scale AI infrastructure and won’t be their last. Alongside Dojo, their home-grown AI supercomputer, Tesla has been partnering closely with Nvidia to ensure they have the GPUs necessary to do all the hard work. Cortex 2.0 is the next iteration, and once it's fully online, we can expect that Tesla’s work on FSD will accelerate even further.
Especially since Elon is planning something truly outrageous once again:
Been thinking about the fastest way to bring a terawatt of compute online.
That is roughly equivalent to all electrical power produced in America today.
With European Tesla owners eagerly awaiting any news on FSD in Europe, we’ve seen Tesla tease FSD, and also point out exactly what the barrier has been - regulatory approval. Now, following the latest meeting of UNECE, new regulatory amendments are set to unlock “System-Initiated Maneuvers” (SIM) on highways across participating European nations.
This development, highlighted by Kees Roelandschap on X, notes that the latest documents from the United Nations Economic Commission for Europe (UNECE) center on amendments to UNECE regulation 171. These changes were formally adopted into UNECE during the WP29 World Forum in March 2025.
Now, the amendment that will enable SIM will come into force on September 26, 2025. This six-month period after approval is standard UNECE procedure and allows objections from party states that would halt the implementation. Objections to UNECE amendments are genuinely rare, with 95% of amendments passing without objection once the World Forum adopts them.
What This Means for FSD in Europe
System-initiated maneuvers will allow your Tesla to perform actions autonomously, such as changing lanes on a highway, while the driver remains fully responsible for supervision. This is a substantial step up from current regulatory standards that only allow for suggested maneuvers or require explicit driver initiation for every automated maneuver.
This inches towards the more normal “hands-off, eyes-on” approach that Tesla has taken with FSD Supervised in North America and China. This regulatory change will help to provide the legal frameworks needed to deploy more advanced autonomy capabilities in Europe, at least matching what’s available on highways in North America.
The UNECE regulation will apply to all countries that adopt its standards, including the European Union, Japan, and South Korea - unless they specifically block it. This is a relatively positive development, but there are some hiccups.
This regulation only allows for system-initiated maneuvers on highways, not low-speed roadways. That means the city streets portion of FSD’s capabilities - including handling ‘Start FSD from Park` and reaching your destination’s parking spot - still won’t be available in Europe.
In addition, the UNECE framework has stricter requirements for driver monitoring and attentiveness - which means that some nags, including the dreaded wheel nag, are likely to remain a key portion of the experience.
Progress on autonomous driving regulations in Europe has been fraught with indecision and caution, which has been a source of frustration for many who are watching the everyday progress of FSD in North America, and more recently, in China. Even with individual countries recently approving testing of FSD on public roads, harmonized UNECE regulations are the key to wider, consistent deployment, which will allow everyday customers to use it as well.
While the path to full parity with North America may be long and involve even more regulatory machinations, the upcoming implementation of System-Initiated Maneuvers is a big step forward for Tesla owners in Europe. It is a key piece of the puzzle that will help Tesla bring some more features of FSD to Europe, assuming the September timeline holds.
