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 CEO Elon Musk revealed today on the social media platform X that legacy automakers, such as Ford, General Motors, and Stellantis, do not want to license the company’s Full Self-Driving suite, at least not without a long list of their own terms.
“I’ve tried to warn them and even offered to license Tesla FSD, but they don’t want it! Crazy,” Musk said on X. “When legacy auto does occasionally reach out, they tepidly discuss implementing FSD for a tiny program in 5 years with unworkable requirements for Tesla, so pointless.”

Musk made the remark in response to a note we wrote about earlier today from Melius Research, in which analyst Rob Wertheimer said, “Our point is not that Tesla is at risk, it’s that everybody else is,” in terms of autonomy and self-driving development.
Wertheimer believes there are hundreds of billions of dollars in value headed toward Tesla’s way because of its prowess with FSD.
A few years ago, Musk first remarked that Tesla was in early talks with one legacy automaker regarding licensing Full Self-Driving for its vehicles. Tesla never confirmed which company it was, but given Musk’s ongoing talks with Ford CEO Jim Farley at the time, it seemed the Detroit-based automaker was the likely suspect.
Tesla’s Elon Musk reiterates FSD licensing offer for other automakers
Ford has been perhaps the most aggressive legacy automaker in terms of its EV efforts, but it recently scaled back its electric offensive due to profitability issues and weak demand. It simply was not making enough vehicles, nor selling the volume needed to turn a profit.
Musk truly believes that many of the companies that turn their backs on FSD now will suffer in the future, especially considering the increased chance it could be a parallel to what has happened with EV efforts for many of these companies.
Unfortunately, they got started too late and are now playing catch-up with Tesla, XPeng, BYD, and the other dominating forces in EVs across the globe.
Tesla is backtracking on a strange adjustment it made to its in-car Navigation feature after numerous complaints from owners convinced the company to make a change.
Tesla’s in-car Navigation is catered to its vehicles, as it routes Supercharging stops and preps your vehicle for charging with preconditioning. It is also very intuitive, and features other things like weather radar and a detailed map outlining points of interest.
However, a recent change to the Navigation by Tesla did not go unnoticed, and owners were really upset about it.
For trips that required multiple Supercharger stops, Tesla decided to implement a naming change, which did not show the city or state of each charging stop. Instead, it just showed the business where the Supercharger was located, giving many owners an unwelcome surprise.
However, Tesla’s Director of Supercharging, Max de Zegher, admitted the update was a “big mistake on our end,” and made a change that rolled out within 24 hours:
The naming change should have happened at once, instead of in 2 sequential steps. That was a big miss on our end. We do listen to the community and we do course-correct fast. The accelerated fix rolled out last night. The Tesla App is updated and most in-car touchscreens should…

The lack of a name for the city where a Supercharging stop would be made caused some confusion for owners in the short term. Some drivers argued that it was more difficult to make stops at some familiar locations that were special to them. Others were not too keen on not knowing where they were going to be along their trip.
Tesla was quick to scramble to resolve this issue, and it did a great job of rolling it out in an expedited manner, as de Zegher said that most in-car touch screens would notice the fix within one day of the change being rolled out.
Additionally, there will be even more improvements in December, as Tesla plans to show the common name/amenity below the site name as well, which will give people a better idea of what to expect when they arrive at a Supercharger.

Dutch regulator RDW confirms Tesla FSD February 2026 target
The regulator emphasized that safety, not public pressure, will decide whether FSD receives authorization for use in Europe.
The Dutch vehicle authority RDW responded to Tesla’s recent updates about its efforts to bring Full Self-Driving (Supervised) in Europe, confirming that February 2026 remains the target month for Tesla to demonstrate regulatory compliance.
While acknowledging the tentative schedule with Tesla, the regulator emphasized that safety, not public pressure, will decide whether FSD receives authorization for use in Europe.
RDW confirms 2026 target, warns Feb 2026 timeline is not guaranteed
In its response, which was posted on its official website, the RDW clarified that it does not disclose details about ongoing manufacturer applications due to competitive sensitivity. However, the agency confirmed that both parties have agreed on a February 2026 window during which Tesla is expected to show that FSD (Supervised) can meet required safety and compliance standards. Whether Tesla can satisfy those conditions within the timeline “remains to be seen,” RDW added.
RDW also directly addressed Tesla’s social media request encouraging drivers to contact the regulator to express support. While thanking those who already reached out, RDW asked the public to stop contacting them, noting these messages burden customer-service resources and have no influence on the approval process.
“In the message on X, Tesla calls on Tesla drivers to thank the RDW and to express their enthusiasm about this planning to us by contacting us. We thank everyone who has already done so, and would like to ask everyone not to contact us about this. It takes up unnecessary time for our customer service. Moreover, this will have no influence on whether or not the planning is met,” the RDW wrote.
The RDW shares insights on EU approval requirements
The RDW further outlined how new technology enters the European market when no existing legislation directly covers it. Under EU Regulation 2018/858, a manufacturer may seek an exemption for unregulated features such as advanced driver assistance systems. The process requires a Member State, in this case the Netherlands, to submit a formal request to the European Commission on the manufacturer’s behalf.
Approval then moves to a committee vote. A majority in favor would grant EU-wide authorization, allowing the technology across all Member States. If the vote fails, the exemption is valid only within the Netherlands, and individual countries must decide whether to accept it independently.
Before any exemption request can be filed, Tesla must complete a comprehensive type-approval process with the RDW, including controlled on-road testing. Provided that FSD Supervised passes these regulatory evaluations, the exemption could be submitted for broader EU consideration.
