Tesla has finally updated the public about the development of its 4680 battery cells, giving new details regarding the development and performance of the new chemistry and additional details about the structural battery pack and how it is performing in crash tests.
4680 Battery Cell
Unveiled at Tesla Battery Day in September 2020, the 4680 battery cell is set to be arguably the most crucial technological development in the company’s mission to accelerate the transition to sustainable energy. During the presentation last year, CEO Elon Musk and VP of Powertrain Drew Baglino outlined the capabilities of the new 4680 battery cell, highlighting five times the energy, a sixteen percent increase in range, six times the power, for less money. The event revealed Tesla’s lengthy research into the 46-millimeter tabless cell and how it performed most efficiently in charging. At the event, Musk said that Tesla is “starting to ramp up production at our pilot 10 GWh factory just around the corner.” Since then, updates have been hard to come by, but we know that companies are building prototypes of the cell and giving them to Tesla in attempts to win a huge contract.

Testing and Efficiency
Tesla said that it has successfully proven the performance and lifetime of the new cell through rigorous testing processes. As of right now, the only thing that remains is ironing out the manufacturing processes of the cell, which continue to plague Tesla’s production output.
The company stated:
-->“We have successfully validated performance and lifetime of our 4680 cells produced at our Kato facility in California. We are nearing the end of manufacturing validation at Kato: field quality and yield are at viable levels, and our focus is now on improving the 10% of manufacturing processes that currently bottleneck production output. While substantial progress has been made, we still have work ahead of us before we can achieve volume production.”
The cell’s development is evidently coming along great, according to the automaker’s analysis. The cell is set to be utilized in the Model Y produced at Giga Texas and Giga Berlin. Both facilities are set to begin manufacturing the all-electric crossover later this year.
Manufacturing has always been one of the most complex riddles that automakers, Tesla included, need to solve to improve efficiency and accuracy. It is a never-ending battle, and finding new and more effective ways to produce and manufacture products accurately and with high quality becomes more complex, despite technological advances. The volume production of the 4680 cell is being held up by the final 10% of manufacturing processes that need to be figured out. However, with less than a year of knowing about the facility, Tesla has evidently made tremendous strides in the manufacturing efforts of the cell, and the company could see robust developments and improvements in production after these bottlenecks are solved.
Finally, Tesla also shed more light on the development of the 4680 structural battery pack. Tesla outlined details on this at its Battery Day event as well, stating that the battery pack would be a part of the vehicle’s increased strength and rigidity. It all came down to design.

“The non-cell portion of the battery has negative mass,” Musk said. “We saved more mass in the rest of the vehicle than in the non-cell portion of the battery. So how do you really minimize the mass of the battery? Make it negative.”
The design increased structural rigidity and stiffness, preventing deformation in the event of a crash. However, testing needed to be performed, and Tesla is doing it in-house. The company stated:
-->“Internal crash testing of our structural pack architecture with a single-piece front casting has been successful.”
Tesla beat Wall Street estimates by posting a revenue of $11.958 billion, non-GAAP Earnings per Share of $1.45, profitability of $1.3 billion, and a free cash flow of $619 million.
Tesla will hold its Q2 2021 Earnings Call at 5:30 PM EST, 2:30 PM PST.

Tesla FSD Supervised ride-alongs in Europe begin in Italy, France, and Germany
The program allows the public to hop in as a non-driving observer to witness FSD navigate urban streets firsthand.
Tesla has kicked off passenger ride-alongs for Full Self-Driving (Supervised) in Italy, France and Germany. The program allows the public to hop in as a non-driving observer to witness FSD navigate urban streets firsthand.
The program, detailed on Tesla’s event pages, arrives ahead of a potential early 2026 Dutch regulatory approval that could unlock a potential EU-wide rollout for FSD.
Hands-Off Demos
Tesla’s ride-along invites participants to “ride along in the passenger seat to experience how it handles real-world traffic & the most stressful parts of daily driving, making the roads safer for all,” as per the company’s announcement on X through its official Tesla Europe & Middle East account.
Sign-ups via localized pages offer free slots through December, with Tesla teams piloting vehicles through city streets, roundabouts and highways.
“Be one of the first to experience Full Self-Driving (Supervised) from the passenger seat. Our team will take you along as a passenger and show you how Full Self-Driving (Supervised) works under real-world road conditions,” Tesla wrote. “Discover how it reacts to live traffic and masters the most stressful parts of driving to make the roads safer for you and others. Come join us to learn how we are moving closer to a fully autonomous future.”
-->Building trust towards an FSD Unsupervised rollout
Tesla’s FSD (Supervised) ride-alongs could be an effective tool to build trust and get regular car buyers and commuters used to the idea of vehicles driving themselves. By seating riders shotgun, Tesla could provide participants with a front row seat to the bleeding edge of consumer-grade driverless systems.
FSD (Supervised) has already been rolled out to several countries, such as the United States, Canada, Australia, New Zealand, and partially in China. So far, FSD (Supervised) has been received positively by drivers, as it really makes driving tasks and long trips significantly easier and more pleasant.
FSD is a key safety feature as well, which became all too evident when a Tesla driving on FSD was hit by what seemed to be a meteorite in Australia. The vehicle moved safely despite the impact, though the same would likely not be true had the car been driven manually.

Swedish union rep pissed that Tesla is working around a postal blockade they started
Tesla Sweden is now using dozens of private residences as a way to obtain license plates for its vehicles.
Two years into their postal blockade, Swedish unions are outraged that Tesla is still able to provide its customers’ vehicles with valid plates through various clever workarounds.
Seko chairman Gabriella Lavecchia called it “embarrassing” that the world’s largest EV maker, owned by CEO Elon Musk, refuses to simply roll over and accept the unions’ demands.
Unions shocked Tesla won’t just roll over and surrender
The postal unions’ blockade began in November 2023 when Seko and IF Metall-linked unions stopped all mail to Tesla sites to force a collective agreement. License plates for Tesla vehicles instantly became the perfect pressure point, as noted in a Dagens Arbete report.
Tesla responded by implementing initiatives to work around the blockades. A recent investigation from Arbetet revealed that Tesla Sweden is now using dozens of private residences, including one employee’s parents’ house in Trångsund and a customer-relations staffer’s home in Vårby, as a way to obtain license plates for its vehicles.
Seko chairman Gabriella Lavecchia is not pleased that Tesla Sweden is working around the unions’ efforts yet again. “It is embarrassing that one of the world’s largest car companies, owned by one of the world’s richest people, has sunk this low,” she told the outlet. “Unfortunately, it is completely frivolous that such a large company conducts business in this way.”
-->Two years on and plates are still being received
The Swedish Transport Agency has confirmed Tesla is still using several different workarounds to overcome the unions’ blockades.
As noted by DA, Tesla Sweden previously used different addresses to receive its license plates. At one point, the electric vehicle maker used addresses for car care shops. Tesla Sweden reportedly used this strategy in Östermalm in Stockholm, as well as in Norrköping and Gothenburg.
Another strategy that Tesla Sweden reportedly implemented involved replacement plates being ordered by private individuals when vehicles change hands from Tesla to car buyers. There have also been cases where the police have reportedly issued temporary plates to Tesla vehicles.

Czech Deputy excited for Tesla FSD, hints at Transport Committee review
The ANO party lawmaker shared his thoughts about FSD in a post on social media platform X.
Martin Kolovratník, a Czech Republic Chamber of Deputies member, has expressed his excitement for Tesla’s Full Self-Driving (FSD) after an apparent constituent called for a quick approval for the advanced safety system.
The ANO party lawmaker, who drives both diesel and EV, shared his thoughts about the matter in a post on social media platform X.
The official’s initial statements
Kolovratník kicked off the exchange with a post outlining his coalition’s efforts to scrap highway toll exemptions for electric vehicles and plug-ins starting in 2027.
“Times have changed. Electric vehicles are no longer a fringe technology, but a full-fledged part of operations. And if someone uses the highway network, they should follow the same rules as everyone else. That’s the basis of fairness,” he wrote.
He emphasized equity over ideology, noting his personal mix of diesel and electric driving. “For this reason, there is no reason to continue favoring one technology at the expense of another… It’s not about ideology, it’s about equal conditions. That’s why we clearly agreed within the new coalition: the exemption for electric vehicles and plug-ins will end in 2027. The decision is predictable, understandable, and economically sound.”
-->Tesla FSD enthusiasm
The conversation pivoted to Tesla’s FSD when X user @robotinreallife, who seems to be one of the official’s constituents, replied that other matters are more important than ending highway exemptions for EVs.
“I’m happy to pay for the highway, but I have a question about a much more fundamental matter: The Netherlands will approve the operation of Tesla FSD in February 26, a technology that has been proven to reduce accidents. The Czech Republic has the option to immediately recognize this certification. Do you plan to support this step so that we don’t unnecessarily delay?” the X user asked.
Kolovratník responded promptly, sharing his own excitement for the upcoming rollout of FSD. “I know about it. I like it and it seems interesting to me. Once we set up the committees and subcommittees, we’ll open it right away in that transport one. Thanks for the tip, I’ll deliver the report,” the official noted in his reply on X.
Kolovratník’s nod to FSD hints at the system’s potentially smooth rollout to Czechia in the coming year. With the Netherlands possibly greenlighting FSD (Supervised) in early 2026, Kolovratník’s commitment could accelerate cross-border certification, boosting FSD’s foray into Europe by a notable margin.
