Kazuo Tadanobu, the CEO of Panasonic’s energy division, recently shared some insights about the company’s upcoming 4680 batteries, which would be sold to longtime partner Tesla. Tadanobu mentioned a number of key observations about the upcoming batteries, particularly on how the 4680 cells could effectively initiate change in the transportation sector.
Panasonic has been working on its 4680 battery for about a year and a half now, and it has not been easy. According to the executive, the development of the new batteries has “taken an immense amount of stamina.” This was because creating 4680 batteries is not as simple as enlarging existing cells. Tadanobu noted that changing the entire shape of the cell took “considerable nerve,” and that Panasonic “didn’t know how they would be received” by Tesla.
Fortunately for Panasonic, Tesla has reportedly acknowledged the Japanese company’s work on its 4680 batteries. Tesla has reportedly deemed Panasonic’s 4680 cells viable, as they meet the level of performance that the American electric vehicle maker is seeking. This is a good sign for Panasonic’s 4680 program, considering that Tesla itself is also ramping the production of its in-house 4680 cells.
Tesla’s home-grown 4680 cells will likely see their initial deployment in the Made-in-Texas Model Y, which will be produced at Gigafactory Texas. So far, Tesla’s 4680 production is limited to the company’s pilot line in Kato Road, close to the Fremont Factory. That’s a facility that has the potential to ramp to 10 GWh per year, but it’s still being improved today, with the company announcing last month that it had produced its 1 millionth 4680 battery cell in January. Tesla would likely need as many 4680 batteries as it could get, considering the launch of upcoming vehicles such as the Cybertruck, Semi, and new Roadster.
Panasonic, for its part, has been sharing its battery partnership with Tesla with rivals such as LG Energy Solution and Contemporary Amperex Technology Co. (CATL), both of which are extremely aggressive. Yet despite the rising competition, such as LG Energy Solution previously stating back in 2020 that it intends to be Tesla’s primary battery supplier in the future, Panasonic believes that the quality and safety of its batteries would speak for themselves.
According to Tadanobu, Panasonic’s advantage in the market lies in its capability to “use craftsmanship to maintain safety even while raising the performance of a battery.” And after leading the development of the next-generation cells, the executive noted that Panasonic would work very hard to retain its spot. “We don’t want to lose,” the Panasonic executive said.
Overall, the executive explained that Panasonic’s hard work in developing 4680 batteries for clients like Tesla is due to the company’s belief that the cells themselves have the potential to change the world of transport. If 4680 battery cells become successful, they would have a considerable impact in lowering the cost of electric vehicles. And if this happens, electric vehicle adoption would likely increase. “We see them as a new path forward,” Tadanobu said.

Tesla Sweden maintains Trelleborg port deal despite union blockade
As noted in a report from Dagens Arbete (DA), Tesla was able to maintain its storage agreement with the Port of Trelleborg.
Tesla Sweden is still storing vehicles at the Port of Trelleborg despite the ongoing blockades against the company from the country’s labor unions.
Tesla still at Port of Trelleborg
As noted in a report from Dagens Arbete (DA), Tesla was able to maintain its storage agreement with the Port of Trelleborg. This allows the company to keep vehicles at the port while imports into Sweden continue. This was despite the Transport Workers’ Union’s blockade, which was aimed at halting the loading and unloading of Tesla vehicles in the area.
Local union leader Jörgen Wärja, chairman of Transport and an employee representative on the port company’s board, confirmed that the agreement was still active. “The agreement has not been terminated. You want to have the money instead of having empty warehouses. I understand the reason, but I do not support it,” Wärja said
The local union leader also noted that he visited Tesla’s storage area earlier this week. “There were a lot of cars. I was surprised that there were so many, actually,” he said.
Tesla had been able to bring vehicles into Sweden via passenger ferries at Trelleborg, a method that unions said allowed the company to bypass the blockade, DA noted. According to estimates from IF Metall, the workaround enabled Tesla to deliver thousands of cars to Sweden each year.
Port defends decision
The Port of Trelleborg did not issue a comment on its current agreement with Tesla, but said it had complied with union sympathy measures. Documents reviewed by Swedish media showed that the contract with Tesla was being extended in six-month intervals.
Port CEO Malin Collin noted that the port would not discuss individual customer arrangements. “We do not go into details regarding any customer agreements. We have continuous dialogue with potential tenants, and this is not unique to any location,” Collin wrote in an email.
The CEO added that the port was following legal requirements related to the labor dispute. “We have taken note of the Transport Workers’ Union’s decision on sympathy measures and are of course following applicable legislation and the requirements placed on us as employers,” Collin said.
Jörgen Wärja, for his part, stated that the issue was not whether Tesla’s imports into Sweden could be fully stopped, but whether the port should provide logistical support to the electric vehicle maker during an active conflict. “The port shouldn’t have anything to do with Tesla at all, we believe,” he said. “It’s purely moral. Whether you honor a conflict or not. If you say you support Transport’s sympathetic actions against Tesla, it becomes a double standard.”

Elon Musk shares insights on SpaceX and Tesla’s potential scale
In a pair of recent posts on X, Musk argued that both companies operate in domains where growth is not linear, but exponential.
Elon Musk outlined why he believes Tesla and SpaceX ultimately dwarf their competitors, pointing to autonomy, robotics, and space-based energy as forces that fundamentally reshape economic scale.
In a pair of recent posts on X, Musk argued that both companies operate in domains where growth is not linear, but exponential.
Space-based energy
In a response to a user on X who observed that SpaceX has a larger valuation than all six US defense companies combined, Musk explained that space-based industries will eventually surpass the total economic value of Earth. He noted that space allows humanity to harness roughly 100,000 times more energy than Earth currently uses, while still consuming less than a millionth of the Sun’s total energy output.
That level of available energy should enable the emergence and development of industries that are simply not possible within Earth’s physical and environmental constraints. Continuous solar exposure in space, as per Musk’s comment, removes limitations imposed by atmosphere, weather, and land availability.
Autonomy and robots
In a follow-up post, Elon Musk explaned that “due to autonomy, Tesla is worth more than the rest of the auto industry.” Musk added that this assessment does not yet account for Optimus, Tesla’s humanoid robot. As per the CEO, once Optimus reaches scaled production, it could increase Earth’s gross domestic product by an order of magnitude, ultimately paving the way for sustainable abundance.
Even before the advent of Optimus, however, Tesla’s autonomous driving system already gives vehicles the option to become revenue-generating assets through services like the Tesla Robotaxi network. Tesla’s autonomous efforts seem to be on the verge of paying off, as services like the Robotaxi network have already been launched in its initial stages in Austin and the Bay Area.

Tesla Cybercab undergoes winter testing as Elon Musk reiterates production start date
CEO Elon Musk confirmed the timeline in a recent post on X, while Tesla’s official social media accounts separately revealed that Cybercab prototypes are now undergoing winter testing in Alaska.
Tesla has reiterated that production of its fully autonomous Cybercab is set to begin in April, even as the company continues expanding real-world testing of the vehicle.
CEO Elon Musk confirmed the timeline in a recent post on X, while Tesla’s official social media accounts separately revealed that Cybercab prototypes are now undergoing winter testing in Alaska.
Musk confirms April Cybercab initial production
In a post on X, Musk reiterated that Cybercab production is scheduled to begin in April, reiterating his guidance about the vehicle’s manufacturing timeline. Around the same time, Tesla shared images showing the Cybercab undergoing cold-weather testing in Alaska. Interestingly enough, the Cybercab prototypes being tested in Alaska seemed to be equipped with snow tires.
Winter testing in Alaska suggests Tesla is preparing the Cybercab for deployment across a wide range of climates in the United States. Cold temperatures, snow, ice, and reduced traction present some of the most demanding scenarios for autonomous systems, making Alaska a logical proving ground for a vehicle designed to operate without a human driver.
Taken together, Musk’s production update and Tesla’s testing post indicate that while the Cybercab is nearing the start of manufacturing, validation efforts are still actively ramping to ensure reliability in real-world environments.
What early Cybercab production might look like
Musk has previously cautioned that the start of Cybercab manufacturing will be slow, reflecting the challenges of launching an all-new vehicle platform. In a recent comment, Musk said initial production typically follows an S-curve, with early output constrained by how many new parts and processes are involved.
According to Musk, both Cybercab and Optimus fall into this category, as “almost everything is new.” As a result, early production rates are expected to be very deliberate before eventually accelerating rapidly as manufacturing processes mature.
“Initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” Musk wrote in a post on X.
