Tesla has moved forward with its expansion of the Kato Road facility, where the 4680 battery cell is developed.
Filings seen by Teslarati show the automaker has continued with its expansion of the Materials Lab, where research and development of the 4680 cell and other battery projects take place.
Tesla filed for revisions to the expansion project in late April, but the Materials Lab has been undergoing modifications since 2021.
Tesla filed its initial permit for the expansion of the Materials Lab at 47400 Kato Road in Fremont in July 2021. It has continued to fill out over the past year and a half, with the most recent filings coming in early and late April of this year.
With the 4680 project continuing to expand in terms of production, Tesla is ramping up manufacturing of the cell to accommodate its appearance in vehicles, including the Model Y that is built at Gigafactory Texas.
Tesla first unveiled the 4680 cell in 2020 at the company’s Battery Day event. The automaker detailed how a new cell design would not only increase battery longevity, but also power and vehicle range, which has not yet been applied to cars with a 4680 pack.
Tesla Model Y vehicles fitted with the 4680 cell have actually shown to have less range than other vehicles, but there are be several reasons for this, and Tesla has gone out of their way to explain it.
Tesla said in a rebuttal to criticism of the range ratings of the 4680 pack:
“Introducing the new cells meant introducing a new variant of the Model Y. We’ve designed Model Y AWD to have an attractive combination of range, performance and price that will be the best fit for many customers and will make Model Y accessible to more customers, furthering our mission. Those interested in an even more capable Model Y should explore Model Y Long Range and Performance. We’ve chosen to put a lower-energy battery pack in Model Y AWD, resulting in lower range, acceleration, and price point.”
We have continued to track developments at both Kato Road and the Fremont Factory as Tesla has hinted in the past it could expand the production facility to make way for higher manufacturing rates.
Tesla 4680 production hits milestone of 868k cells in seven days
Tesla has a lofty goal of producing 1.8 million cars this year, and with recently expanded efforts at both Giga Texas and Giga Berlin, the automaker seems on track to reach this. If it does expand the Fremont Factory as well, growth to the 4680 cell project only seems logical.

Tesla hacker finds lifesaving FSD suggestions in 2025.32.3
The feature could drastically reduce instances of drivers operating their vehicles while distracted or exhausted.

A Tesla hacker has shared references to what could very well be lifesaving FSD suggestions in software update 2025.32.3.
The feature could drastically reduce instances of drivers operating their vehicles while distracted or exhausted.
New FSD features
As per longtime Tesla hacker @greentheonly, the EV maker’s drowsiness and lane departure suggestions in 2025.32.3 reference FSD. The hacker shared two alerts that specifically suggest the use of FSD, such as “Lane drift detected. Let FSD assist so you can stay focused,” and “Drowsiness detected. Stay focused with FSD.”
The hacker noted that the updated messages in 2025.32.3 are quite interesting because Tesla still advises drivers to be fully alert when using FSD Supervised. Thus, it is quite interesting to see the company advising users to use FSD when they seem unfocused or tired. That being said, FSD is still a supervised solution for now, but the system itself is already very capable, so the company’s updated alerts are not surprising.
Steps to FSD Unsupervised
Such warning messages would definitely make more sense once Tesla actually rolls out FSD Unsupervised. The system seems to be just waiting for regulatory approval for now, considering that it is already being used in vehicles that are coming off the production line at the Fremont Factory and Giga Texas. Tesla is also now using a driverless system for its Robotaxi services in Austin, as well as its autonomous ride-hailing service in the Bay Area.
For now, Tesla is hard at work preparing for the impending rollout of FSD V14, which Elon Musk has stated will be a notable improvement from the already-impressive performance of FSD V13. As per Musk, Teslas running FSD V14 will feel “sentient.” He also noted that the system “feels alive.”

Elon Musk assures Tesla investors he will enhance his security detail
Musk’s comments were posted on X in the aftermath of the slaying of conservative commentator Charlie Kirk.

Tesla CEO Elon Musk has assured TSLA investors that he would be enhancing his security detail.
Musk’s comments were posted on X in the aftermath of the slaying of conservative commentator Charlie Kirk.
Aggressive critics
Kirk was slain during a speaking engagement at Utah Valley University as part of Turning Point USA’s first event on a tour of college campuses, as noted in a Politico report. Kirk was a notable voice in the conservative movement and a close ally of the Trump administration, which led to aggressive critics openly wishing him harm.
Elon Musk, due to his contributions to the Trump campaign and his later work with the Department of Government Efficiency (DOGE), has also attracted a substantial amount of vitriol from critics. Tesla owners and the company itself suffered attacks due to critics’ anger towards Musk, with several stores and cars being vandalized or victimized in arson attacks.
Despite having stepped back from his work with DOGE, Musk remains a target among critics online, with some still calling for the CEO to get the “Luigi Mangione” treatment. These sentiments were notable after Kirk’s slaying, with some users on platforms such as Reddit and Bluesky arguing that Musk or Donald Trump should be next after Kirk.
Concerns and assurances
In the aftermath of Kirk’s slaying, numerous Tesla retail investors called on the company’s Board of Directors to bolster Elon Musk’s security detail. With some social media users openly calling for Musk to be slain next, such a request made sense. This was highlighted by Tesla investor Alexandra Merz, who called on the Tesla Board to drastically increase the company’s budget for Elon Musk’s security, which currently stands at just $3.3 million annually, or about $235,000 per month.
In response to the Tesla investor’s comments, Musk responded that he would “definitely need to enhance security.” Musk’s response was well appreciated by the Tesla and electric vehicle community as a whole, with some users on X stating that the CEO must be kept safe.
Musk is a key part of Tesla, and this was highlighted in the company’s proposed 2025 CEO performance award, which outlines a path towards the company attaining a market cap of $8.5 trillion. In its filing, Tesla highlighted that Elon Musk’s leadership is a fundamental part of the company and its future.

This signature Tesla feature is facing a ban in one of its biggest markets
The report indicates that Chinese government agencies have concerns “about failure rates and safety issues with the flush design.”

A signature Tesla feature is under fire in one of the company’s largest markets, as regulators in one EV hot spot are mulling the potential ban of a design the automaker implemented on some of its vehicles.
Tesla pioneered the pop-out door handle on its Model S back in 2012, and CEO Elon Musk felt the self-presenting design was a great way to feel like “you’re part of the future.”
It is something that is still present on current Model S designs, while other vehicles in the Tesla lineup have a variety of handle aesthetics.
According to Chinese media outlet Mingjing Pro, the company, along with others using similar technology, is facing scrutiny on the design as regulators consider a ban on the mechanism. These restrictions would impact other companies that have utilized pop-out handles on their own designs; Tesla would not be the only company forced to make changes.
The report indicates that Chinese government agencies have concerns “about failure rates and safety issues with the flush design.”
However, EVs are designed to be as aerodynamically efficient as possible, which is the main reason for this design. It is also the reason that many EVs utilize wheel covers, and sleek and flowing shapes.
However, the Chinese government is not convinced, as they stated the aerodynamic improvements are “minimal,” and safety issues are “significantly elevated,” according to The Independent.
The issue also seems to be focused on how effective the handle design is. According to data, one EV manufacturer, which was not specified in the report, has 12 percent of its total repairs are door handle failure fixes.
There are also concerns about the handles short-circuiting, leaving passengers trapped within cars. Tesla has implemented emergency latch releases in its vehicles that would prevent passengers from getting stuck in their cars in cases of electric malfunctions or failures.
However, evidence from the Chinese Insurance Automotive Technology Research Institute (C-IASI) suggests that 33 percent of door handles using this design fail to function after a side impact.
Obviously, Tesla and other automakers could introduce an alternative design to those vehicles that are affected by the potential restrictions China intends to impose. The regulation would take effect in July 2027.
