Tesla’s new 4680 battery cells have been deployed in working vehicles for months
Elon Musk recently clarified that Tesla’s new 4680 cells are already being deployed in some of its vehicles as prototypes. Even more interesting is that the next-generation batteries have already been in use for several months, though the CEO did not state which of its vehicles are equipped with the 4680 Roadrunner batteries.
The Tesla CEO related his update in a recent post on Twitter. While responding to a question about the company’s strategy with its cathodes and its suppliers, Musk noted that Tesla’s own battery cells are already powering some of its cars. That being said, Musk clarified that ultimately, prototypes such as cars that currently run on the company’s 4680 cells are trivial, as they are incomparably simpler than actual volume production.
“We’re only doing high energy nickel ourselves, at least for now. Also, maybe the presentation wasn’t clear that we’ve actually had our cells in packs driving cars for several months. Prototypes are trivial, volume production is hard,” Musk wrote.
Interestingly enough, Elon Musk noted that Tesla is only producing cells that feature high-energy nickel cathodes for now. During Battery Day, Tesla’s slide outlining its cathode strategy listed the Semi and the Cybertruck as vehicles that will be using high-energy nickel. However, the CEO did not confirm if the Cybertruck prototype or the twin Semis doing road tests across the United States are now equipped with 4680 cells. Such a scenario seems plausible as both vehicles only have prototypes today.
Using 4680 cells for the Cybertruck and the Semi would be strategic for Tesla, especially since both are heavy-duty machines that are designed to be as tough as possible. The Cybertruck is quite literally created to topple the kings of the pickup market, and the Semi is designed to disrupt the long-haul segment, which is known for its consistent, heavy demands for its vehicles. Needless to say, Tesla’s mettle as an automaker will be put to the test by the Cybertruck and Semi, and their 4680 high-nickel cells could be their trump card against the competition.
That being said, the first vehicle that would likely be released with Tesla’s 4680 cells will be the Model S Plaid, which was announced on Battery Day. The Model S Plaid is Tesla’s most insane sedan yet, with its 0-60 mph time of less than 2 seconds, its top speed of 200 mph, sub-9-second quarter-mile time, and three motors that produce 1,100 hp. The fact that the vehicle has a range of over 520 miles despite its performance-oriented tune hints at just how disruptive Tesla’s 4680 cells really are. The Model S Plaid was announced for a 2021 release date, though speculations are abounding that the vehicle may see a release sooner than expected.
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.
