Panasonic finds itself in need of some Tesla-style boldness as it enters its next era
Tesla’s oldest battery partner, Panasonic, is finding itself at a crossroads once more. With Chief Executive Kazuhiro Tsuga poised to step down next June, the massive Japanese conglomerate is feeling some pressure to optimize and streamline itself. To accomplish this, Panasonic may need to channel one of its key battery partners, Tesla, and its CEO, Elon Musk, to make the bold decisions needed to thrive in a new era.
When Tsuga took Panasonic’s reins eight years ago, he stated that his first priority would be to return the massive conglomerate into a profitable “normal company.” He did not disappoint. Tsuga stemmed a record loss by pulling the company out of the plasma television market and repositioning the firm as an automotive-and-housing conglomerate. The veteran Japanese executive also did something unexpected: he initiated a $5 billion battery manufacturing tie-up with Tesla in 2014.
Tsuga’s strategy of partnering with Tesla, then an unproven electric car maker, and a CEO known for a Tony Stark-like persona, was considered a courageous move on the Japanese conglomerate’s part. The partnership of the experienced Japanese veteran and assertive US startup bore fruit, with Gigafactory Nevada becoming the world’s largest battery facility. Its operations with Tesla are even closing in on its first annual profit. But the journey to this point was not easy.

As noted in a Financial Times report, Panasonic and Tesla clashed over the years, and these tensions reportedly manifested themselves when the Japanese firm decided to not invest in Gigafactory Shanghai. This resulted in Tesla partnering with other suppliers like LG Chem and Contemporary Amperex Technology Co., Limited (CATL). Tesla has also announced plans to start producing its own 4680 tabless cells for its vehicles and energy storage products.
As the outgoing Panasonic CEO prepares to step down in June, his promise of running a “normal company” is leaving a bitter aftertaste to the company he will leave behind. Over the years, rivals such as Sony and Hitachi have gone on massive divestment initiatives to streamline their businesses. And while Panasonic has followed a similar path, executives continue to struggle to define what kind of company it is. Newly-appointed chief executive Yuki Kusumi, who is poised to succeed Tsuga, referenced this when he stated that Panasonic could achieve growth if it could optimize businesses that excelled in its portfolio, which currently stretches across a whopping 520 subsidiaries.

The outgoing Panasonic CEO, as a final departing measure, is hoping to change the company into a holding company structure, which is similar to a move that rival Sony will make around April. According to Panasonic, the shift, which is expected to be completed in 2022, could help accelerate decision-making across the conglomerate by running its units independently. Yet even this strategy poses challenges for Panasonic since unlike Sony, which has found its “core” in the games, films, animation, and the music segment, Panasonic’s “core” still seems unclear. This difference is evident when one looks at the two Japanese firms’ performance in the market. Sony has increased 78% since February while Panasonic has dropped 30%.
But things may be looking up for Panasonic. When he announced Panasonic’s shift to a holding company, Tsuga resurrected car batteries as a “core” by branding it as an “energy business.” Thanks in part to this, as well as the ongoing expansion of profitable projects like Gigafactory Nevada, Panasonic’s next CEO, Yuki Kusumi, would be taking control of a company that is in a much better financial position as the one handed over to his predecessor. As highlighted by the Financial Times, if Kusumi would like to usher in a revival or a breakthrough of sorts for Panasonic in the coming years, he would have to channel less of his predecessor’s “normal company” strategy and more of the boldness characteristic of partners like Tesla.
Markets like the battery industry are only just heating up, after all. While Tesla has stated that it intends to keep and grow its partnership with suppliers like Panasonic despite its own battery production plans, competitors like LG Chem and CATL are not sitting out the next few years. LG has even posted a bold challenge of sorts to the Japanese conglomerate recently, with the South Korean firm stating that it has every intention to become Tesla’s main battery supplier in the near future, effectively taking Panasonic’s place. With some Elon Musk-style boldness, however, perhaps Panasonic could still keep its lead in the battery sector, and perhaps even increase its reach in the growing EV segment.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”

One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.

Tesla updates Cybertruck owners about key Powershare feature
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
