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.

Tesla wins another award critics will absolutely despise

Tesla earned an overall score of 49 percent, up 6 percentage points from the previous year, widening its lead over second-place Ford (45 percent, up 2 points) to a commanding 4-percentage-point gap. The company also excelled in the Fossil Free & Environment category with a 50 percent score, reflecting strong progress in reducing emissions and decarbonizing operations.

Tesla just won another award that critics will absolutely despise, as it has been recognized once again as the company with the most sustainable supply chain.

Tesla has once again proven its critics wrong, securing the number one spot on the 2026 Lead the Charge Auto Supply Chain Leaderboard for the second consecutive year, Lead the Charge rankings show.

This independent ranking, produced by a coalition of environmental, human rights, and investor groups including the Sierra Club, Transport & Environment, and others, evaluates 18 major automakers on their efforts to build equitable, sustainable, and fossil-free supply chains for electric vehicles.

Tesla earned an overall score of 49 percent, up 6 percentage points from the previous year, widening its lead over second-place Ford (45 percent, up 2 points) to a commanding 4-percentage-point gap. The company also excelled in the Fossil Free & Environment category with a 50 percent score, reflecting strong progress in reducing emissions and decarbonizing operations.

Perhaps the most impressive achievement came in the batteries subsection, where Tesla posted a massive +20-point jump to reach 51 percent, becoming the first automaker ever to surpass 50 percent in this critical area.

Tesla achieved this milestone through transparency, fully disclosing Scope 3 emissions breakdowns for battery cell production and key materials like lithium, nickel, cobalt, and graphite.

The company also requires suppliers to conduct due diligence aligned with OECD guidelines on responsible sourcing, which it has mentioned in past Impact Reports.

While Tesla leads comfortably in climate and environmental performance, it scores 48 percent in human rights and responsible sourcing, slightly behind Ford’s 49 percent.

The company made notable gains in workers’ rights remedies, but has room to improve on issues like Indigenous Peoples’ rights.

Overall, the leaderboard highlights that a core group of leaders, Tesla, Ford, Volvo, Mercedes, and Volkswagen, are advancing twice as fast as their peers, proving that cleaner, more ethical EV supply chains are not just possible but already underway.

For Tesla detractors who claim EVs aren’t truly green or that the company cuts corners, this recognition from sustainability-focused NGOs delivers a powerful rebuttal.

Tesla’s vertical integration, direct supplier contracts, low-carbon material agreements (like its North American aluminum deal with emissions under 2kg CO₂e per kg), and raw materials reporting continue to set the industry standard.

As the world races toward electrification, Tesla isn’t just building cars; it’s building a more responsible future.

Tesla Full Self-Driving likely to expand to yet another Asian country

“We are aiming for implementation in 2026. [We are] doing everything in our power [to achieve this],” Richi Hashimoto, president of Tesla’s Japanese subsidiary, said.

Tesla Full Self-Driving is likely to expand to yet another Asian country, as one country seems primed for the suite to head to it for the first time.

The launch of Full Self-Driving in yet another country this year would be a major breakthrough for Tesla as it continues to expand the driver-assistance program across the world. Bureaucratic red tape has held up a lot of its efforts, but things are looking up in some regions.

Tesla is poised to transform Japan’s roads with Full Self-Driving (FSD) technology by 2026.

Richi Hashimoto, president of Tesla’s Japanese subsidiary, announced the ambitious timeline, building on successful employee test drives that began in 2025 and earned positive media reviews. Test drives, initially limited to the Model 3 since August 2025, expanded to the Model Y on March 5.

Once regulators approve, Over-the-Air (OTA) software updates could activate FSD across roughly 40,000 Teslas already on Japanese roads. Japan’s orderly traffic and strict safety culture make it an ideal testing ground for autonomous driving.

Hashimoto said:

“We are aiming for implementation in 2026. [We are] doing everything in our power [to achieve this].”

The push aligns with Hashimoto’s leadership, which has been credited for Tesla’s sales turnaround.

In 2025, Tesla delivered a record 10,600 vehicles in Japan — a nearly 90% jump from the prior year and the first time exceeding 10,000 units annually.

The strategy shifted from online-only sales to adding 29 physical showrooms in high-traffic malls, plus staff training and attractive financing offers launched in January 2026. Tesla also plans to expand its Supercharger network to over 1,000 points by 2027, boosting accessibility.

This Japanese momentum reflects Tesla’s broader international expansion. In Europe, Giga Berlin produced more than 200,000 vehicles in 2025 despite a temporary halt, supplying over 30 markets with plans for sequential production growth in 2026 and battery cell manufacturing by 2027.

While regional EV sales faced headwinds, the factory remains a cornerstone for Model Y deliveries across the continent.

In Asia, Giga Shanghai continues to be recognized as Tesla’s powerhouse. China, the company’s largest market, saw January 2026 deliveries from the plant rise 9 percent year-over-year to 69,129 units, with affordable new models expected later this year.

FSD advancements, already progressing in the U.S. and South Korea, are slated for Europe and further Asian rollout, complementing plans to expand Cybercab and Optimus to new markets as well.

With OTA-enabled autonomy on the horizon and retail strategies paying dividends, Tesla is strengthening its footprint from Tokyo showrooms to Berlin assembly lines and Shanghai exports. As Hashimoto continues to push Tesla forward in Japan, the company’s global vision for sustainable, self-driving mobility gains traction across Europe and Asia.

Tesla ships out update that brings massive change to two big features

“This change only updates the name of certain features and text in your vehicle,” the company wrote in Release Notes for the update, “and does not change the way your features behave.”

Tesla has shipped out an update for its vehicles that was caused specifically by a California lawsuit that threatened the company’s ability to sell cars because of how it named its driver assistance suite.

Tesla shipped out Software Update 2026.2.9 starting last week; we received it already, and it only brings a few minor changes, mostly related to how things are referenced.

“This change only updates the name of certain features and text in your vehicle,” the company wrote in Release Notes for the update, “and does not change the way your features behave.”

The following changes came to Tesla vehicles in the update:

  • Navigate on Autopilot has now been renamed to Navigate on Autosteer
  • FSD Computer has been renamed to AI Computer

Tesla faced a 30-day sales suspension in California after the state’s Department of Motor Vehicles stated the company had to come into compliance regarding the marketing of its automated driving features.

The agency confirmed on February 18 that it had taken a “corrective action” to resolve the issue. That corrective action was renaming certain parts of its ADAS.

Tesla discontinued its standalone Autopilot offering in January and ramped up the marketing of Full Self-Driving Supervised. Tesla had said on X that the issue with naming “was a ‘consumer protection’ order about the use of the term ‘Autopilot’ in a case where not one single customer came forward to say there’s a problem.”

It is now compliant with the wishes of the California DMV, and we’re all dealing with it now.

This was the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” names. Previous Transportation Secretary Pete Buttigieg was one of those federal-level employees who had an issue with the names “Autopilot” and “Full Self-Driving.”

Tesla sued the California DMV over the ruling last week.
