Panasonic said on Wednesday that it has shipped samples of Tesla’s 4680 cell to the automaker ahead of mass production. Panasonic detailed its plans for the production timeline during the first day of the company’s annual investor event.

“A pilot line, created first in Japan, made it possible to start large-scale prototype production in May,” Kazuo Tadanobu, Panasonic’s energy business CEO said during the event.

Pansonic believes mass production of the 4680 cell is set to begin in March 2023 when the company’s fiscal year starts. Panasonic’s Wakayama plant will initially handle the production of the cell. It will then be shifted to North America.

Tadanobu has not committed in the past to produce the 4680 cells in the United States, but now that he is stating the company will transition production to North America, it could bring another plant to the U.S.

Reuters, who initially reported on Panasonic shipping 4680 samples to Tesla, said the company is looking at sites in Kansas and Oklahoma, people familiar with the matter said.

Panasonic only has Tesla as a client for the new cells.

Tesla’s 4680 battery cell is the automaker’s most recent discovery in terms of EV technology, as it offers significantly more power, energy density, and range than previous battery designs. It was unveiled in late 2020 by CEO Elon Musk and other executives at the company’s Battery Day event. Tesla has been producing the cells at a facility near the Fremont Factory in Northern California, but only in limited quantities. Tesla had produced its 1 millionth 4680 cell in January. However, industry researcher Benchmark Mineral Intelligence estimated that one million 4680 cells are enough for about 1,200 Tesla Model Ys.

Tesla has been installing the 4680 battery packs in some Model Ys manufactured at the company’s new facility in Austin, Texas.

Tesla has opened its first job listing specifically for the next-generation Roadster, hinting at some substantial progress on the company’s long-awaited flagship all-electric supercar. 

The company is looking for a Manufacturing Engineer to support the development and launch of new battery manufacturing equipment, which would likely be pivotal to the Roaster, considering its teased performance and range.

Tesla’s next-generation Roadster batteries

As per Tesla’s Careers website, the Roadster Manufacturing Engineer’s tasks would include ideating equipment concepts, developing specifications, validating processes, and addressing production bottlenecks. Tesla emphasized that the position involves collaboration across domestic and international sites, supporting equipment factory acceptance tests and assisting operations teams, with expected travel under 50 percent. 

“In this role, you will take large-scale manufacturing systems for new battery products and architectures from the early concept development stage through equipment launch, optimization, and handover to local operations teams. Battery development is at the heart of our company, and this is an exciting opportunity to work directly on the central challenges for the all-new Roadster product architecture while still in its early development stages,” the job listing noted.

The opening marks one of the first public hiring efforts explicitly tied to the next-gen Roadster, suggesting that the vehicle’s development might be approaching its initial manufacturing phase. The fact that the new Roadster’s first job opening is related to its battery is interesting, as the vehicle was unveiled with a range of 620 miles way back in late 2018. Though at the time, Elon Musk also noted that the Roadster would be fitted with a 200 kWh battery, twice the size of the batteries used in the Model S and Model X.

Musk teases “most epic demo ever” and fuels Roadster speculation

Back in July, Elon Musk teased a major demonstration at the Tesla Design Studio in Hawthorne, California, scheduled for the end of the year. Musk shared on X that he had just visited the studio, calling the upcoming event the “most epic demo ever by one of year. Ever.”

The statement immediately prompted speculations that Tesla may finally be ready to reveal the production version of the next-generation Roadster. Originally unveiled alongside the Semi in 2018, the Roadster has remained under wraps while the company scaled production of other models. Since its unveiling, however, the Roadster’s rollout has been pushed back in favor of the original Model Y, the refreshed Model S and X, the Cybertruck, the refreshed Model 3, the Semi, and the new Model Y.

At the time of its unveiling, the next-generation Roadster was teased to be nothing short of a monster, with a 0-60 mph time of 1.99 seconds and a top speed of over 250 mph. Elon Musk also teased that the next-generation Roadster would have a range of 620 miles per charge. Later, the CEO noted that the Roadster should be able to achieve a 0-60 mph launch of less than 1 second, thanks to the vehicle’s SpaceX package. Musk has also noted recently that the next-generation Roadster would be “beyond a car.”

Tesla China Vice President Grace Tao recently shared new details on the company’s solar initiatives in some of its facilities across Shanghai. 

In a post on Weibo, the Tesla executive stated that Gigafactory Shanghai’s rooftop solar installation now generates an impressive amount of clean energy, and other sites are following suit.

Tesla China’s rooftop solar initiatives

As per Tao’s post, Giga Shanghai’s rooftop solar system produces about 11 million kWh of electricity per year. This helps reduce carbon emissions by an estimated 4,600 tons annually.

The Shanghai Megafactory, which produces Megapack batteries, is also being fitted with solar panels. Once operational, it is expected to generate an additional 6 million kWh per year and further lower carbon emissions by roughly 2,500 tons.

“At present, the roof of the Shanghai Super Factory is covered with photovoltaic panels, which can generate 11 million kWh of electricity annually and reduce carbon emissions by 4,600 tons. The Shanghai Energy Storage Super Factory next door is also installing photovoltaic panels, which is expected to generate an additional 6 million kWh a year and reduce carbon emissions by 2,500 tons,” Tao wrote in her post.

Tesla expands solar and storage efforts

Beyond its manufacturing hubs, Tesla is extending its renewable energy strategy to service centers and retail operations in China. Tao stated that the roof of Tesla’s Shanghai Kangqiao Direct Body and Paint Center already produces around 400,000 kWh of green electricity each year, reducing emissions by yet another 170 tons.

She highlighted that Tesla’s goal is to ensure clean electricity powers the full lifecycle of its products, from manufacturing and storage to on-road charging. “The manufacture, storage, and use of clean electricity runs through the entire chain of Tesla products, and is also the contribution of every Tesla owner to a sustainable tomorrow for the earth,” Tao stated.

United States President Donald Trump has confirmed that his relationship with Elon Musk has improved following months of tension. 

Speaking with reporters aboard Air Force One, Trump stated that he and Elon Musk have spoken “on and off, a little bit” since meeting at slain conservative activist Charlie Kirk’s memorial service in September. Trump also noted that he now considers their relationship “good.”

Trump stated that his feud with Musk has cooled after ‘stupid moment’

Trump addressed the pair’s earlier feud, which unfolded publicly earlier this year after Musk publicly opposed Trump’s “Big Beautiful Bill” and later stepped away from his administration’s advisory role tied to the DOGE initiative. The U.S. president addressed the dispute, describing it as a brief lapse in judgment, as noted in an Insider report.

“He had a bad spell, he had a bad period. He had a bad moment,” Trump said. “It was a stupid moment in his life, very stupid. I’m sure he’d tell you that. But I like Elon, and I suspect I always will.”

Trump’s remarks suggest a thaw in what had been one of the United States’ most visible political rifts, which saw Musk accusing Trump of being on Epstein’s list and Trump threatening to take away Tesla and SpaceX’s subsidies. In his recent comments, however, Trump noted that “I like Elon, I’ve always liked him.”

Musk has mostly stayed quiet on Trump, but he still criticizes administration officials

Musk has publicly toned down his criticism of Trump in recent months, pausing discussion of a third political party he once floated after Trump’s megabill passed. While his stance toward the former president appears to have softened, with the two men publicly making peace during Kirk’s memorial, Musk has continued to spar with members of Trump’s administration.

Just last week, he engaged in a dispute with Transportation Secretary Sean Duffy over NASA leadership after Duffy opened one of SpaceX’s contracts for review. Musk expressed his frustration against Duffy on X, stating that “Sean Dummy is trying to kill NASA” and pledging that SpaceX would be taking humans back to the Moon with Starship before any other company.
