Tesla partner Panasonic is working on a prototype 4680 battery cell production line
During a briefing on Thursday, Panasonic’s Chief Financial Officer Hirokazu Umeda noted that the Japanese tech conglomerate is preparing to produce 4680 battery cells for Tesla. Umeda also mentioned that Panasonic started working on a prototype manufacturing line for the 4680 cells after Tesla’s Battery Day event last month.
“We have considerable know-how for that battery. We started working on it immediately after Tesla’s Battery Day and are also preparing to set up a prototype production line in parallel,” Umeda said, as per a NASDAQ report.
The 4680 cells, which feature 500% times more energy and 6X more power than the company’s existing batteries, are key to Tesla’s plans for the coming years. Tesla executives Elon Musk and Drew Baglino explained on Battery Day that the 4680 cell, which should pave the way for terawatt-hour scale battery production, is pertinent in the company’s push to accelerate the advent of sustainable energy.
Panasonic’s push to produce 4680 cells for Tesla is a rather bold move for the Japanese conglomerate, especially as the two companies’ joint venture at Gigafactory Nevada has experienced challenges over the years. The challenges experienced by Tesla and Panasonic were so notable that speculations from critics at one point suggested that the Japanese firm might cut ties with the American EV maker.
Needless to say, these speculations did not come to pass, especially as sales of Tesla’s electric cars stabilized profits for the EV maker and its battery partner. Tesla has so far accomplished five consecutive profitable quarters, and Panasonic, for its part, reported an 11% increase in second-quarter operating profit, beating analyst estimates.
In the recent briefing, the CFO further stated that apart from the prototype 4680 production line, Panasonic is also launching an additional production line at Giga Nevada. This additional line is estimated to boost the plant’s total capacity by 10% to about 38-39 GWh a year by 2022. “We are targeting a profit margin of around 5% at our Tesla battery business within two to three years,” Umeda said.
Ultimately, Panasonic’s development of a prototype 4680 cell production line for Tesla bodes well for the electric car maker’s rollout of its next-generation batteries. Despite Tesla ramping its own battery cell production activities at its pilot site in Fremont, after all, the company has emphasized that it needs partners like Panasonic, LG Chem, and CATL to produce more batteries than ever before. Panasonic’s prototype 4680 line seems to be a step towards this direction.

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.
Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
Sweden’s IF Metall union has announced that it is ending all protests against Tesla, effective immediately.
The union said in a statement this morning:
“There seems to be no limits to the length Tesla would go to keep unions out of their operations. Unfortunately, they have managed to pay their way out in Sweden. At least that has given the former IF Metall members more money in their pocket, but the insecurity of not having a union or a collective agreement still remains.”
IF Metall has been after Tesla in Sweden for the past three years, attempting to push unionized operations into its factories. Tesla, on the other hand, has given its employees the chance to unionize in various markets. However, the organization says that Tesla has “bought out all of its striking members.”
🚨 NEW: IF Metall has decided to end all industrial action against Tesla in Sweden, effective immediately.

“Today, we end our industrial action against Tesla. We do so because it can no longer have an effect – not because our principles have changed,” a written statement said.
Over the past three years, IF Metall has definitely been a thorn in the side of Tesla and its operations in Sweden. The primary strike started in October 2023, when IF Metall members at Tesla’s Swedish Service Centers refused to work.

Strikes extended to blockades and work stoppages at non-Tesla-owned repair shops that service Teslas. This limited and stopped anything related to warranties, transport damage, and other work on Teslas ending, eliminating work arounds for customers.
Sympathy strikes followed, as postal workers, dock workers, electricians, and other tradesmen stopped working. Add in lawsuits and other pressures, and you get the full scope of what strategies the union has used against Tesla over the past several years.
But now, it’s all over.
“We will continue to defend the right of workers to organize. We will continue to fight for collective bargaining. And we will continue to stand in solidarity with workers and trade unions facing similar challenges elsewhere – just as you have stood with us,” IF Metall said.
