X user,@MarcoRPi1, known for Supercharger updates, posted details on Tesla's new V4 Supercharger, offering an unprecedented look at the next-gen charging tech. This unofficial, but credible source revealed some additional details on Tesla’s V4 Superchargers. The specs list the units as capable of outputting the current 250kW, although this is expected to increase in the future. The stalls boast a wide voltage range to accommodate various EV models. The post, which the user warns might be deleted later, showed that Tesla continues to push the envelope in EV charging capabilities.
V4 Supercharger
MarcoRPi1
The V4 Supercharger supports a wide array of international charging standards, such as Tesla’s NACS, as well as CCS1, CCS2, and GB/T, possibly catering to other manufacturers who wish to buy and white label Superchargers. Recently Tesla sold 100 million dollars worth of Superchargers to BP Pulse. The V4’s universal cable reach ensures a more vehicle-agnostic charging experience, bolstering consumer confidence in EV adoption. Key features of this advanced charging post include support for global and open communication standards, unmatched ergonomics, a revenue-grade DC energy meter, and an optional payment module that is required in some regions. It has a flood tolerance of up to one meter and a compact design, making it an ideal solution for space-constrained urban environments.
First Reactions to Specs: Concerns Over Practicality
The detailed specs, however, were met with immediate skepticism. @IeZSC2Maps was quick to criticize, citing personal experiences of the charging cable disconnecting in harsh weather, mocking the claim of a "best in class user experience."
This criticism echoes a sentiment we've previously reported. A Tesla enthusiast and Model 3 owner, @RoamingNorway, expressed grievances with the V4 Supercharger. He pointed out that the heavier cables compromised flexibility, and design flaws led to frequent disconnections during use. Despite a modest following, his observations struck a chord within the Tesla community and signaled to the company that all was not well. Tesla's official charging account, @TeslaCharging, did not turn a deaf ear to these complaints. They acknowledged the feedback, promising swift action to refine the cable dock and improve flexibility.
Expanding Horizons: Tesla's V4 Network Growth
The ongoing expansion of the V4 Supercharger network across Europe, including new installations and upgrades from older versions, indicates Tesla's commitment to universal charging standards. With over 55,000 Superchargers worldwide, Tesla is paving the way for the future of clean transportation.
The V4 Supercharger's advanced technology, paired with Tesla's readiness to address and rectify user concerns, paints a picture of a company that is relentless in its pursuit of innovation yet grounded in customer experience. As Tesla forges ahead with upgrades and network expansion, the V4 Supercharger is set to become the new gold standard in EV charging, so the company better get it right.

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.
