Tesla’s Gigafactory Texas-built Model Y will equip the company’s Structural Battery Pack and revolutionary 4680 cells, CEO Elon Musk confirmed on the company’s Q4 2021 Earnings Call.

Musk confirmed that Tesla has been building many Model Y units at Gigafactory Texas in recent days as the factory nears production approval. Upon updating listeners that Tesla would begin deliveries of the Texas built-Model Y when the vehicle receives an approval certification, Musk confirmed that the 4680 battery cells and Structural Battery Pack system would be used in vehicles built at Gigafactory Texas.

Tesla updated the timeline for the plant in its Shareholder Deck by stating, “Builds of Model Ys started in late 2021 at Gigafactory Texas. After final certification of Austin-made Model Y, we plan to start deliveries to customers.”

4680 Cells

Interestingly, Tesla also stated in its Q4 2021 Shareholder Deck that Model Ys built at Gigafactory Berlin in Germany would not initially equip the 4680 cells. These vehicles will equip 2170 battery cells at first, which have been used in the Model 3 and Model Y since their early production days.

The 4680 cell aims to revolutionize lithium-ion batteries used in electric vehicles. It is 46 millimeters wide and 80 millimeters long and will increase energy density by five times, increase range by sixteen percent, and improve power output by six times. The cell has been in development since 2020, kept behind the doors of the Kato Road facility.

Drew Baglino, SVP of Powertrain for Tesla, said that “4680 cells are not a constraint to our 2022 volume plans.” He added that he expects the first vehicles equipping the 4680 cells to be delivered by the end of Q1 2022.

Structural Battery Pack

Musk also confirmed the Gigafactory Texas Model Ys would equip the Structural Battery Pack, which will increase vehicle rigidity and structural integrity.

Tesla hinted that the Structural Pack was being included in cars when it released the Shareholder Deck just before the Earnings Call began.

The Structural Battery Pack works like an aircraft wing and will improve the structural integrity of Tesla vehicles. While the casting improves manufacturing efficiency and strength, the positioning of structural batteries eliminates excess structure from the battery packs, increasing density. “The non-cell portion of the battery has negative mass,” Musk said. “We saved more mass in the rest of the vehicle than in the non-cell portion of the battery. So how do you really minimize the mass of the battery? Make it negative.”

The idea is that individual cells could be positioned more efficiently because excessive structures within the pack itself were eradicated. The new Structural Battery Pack design is completely free of any negative mass, which improves pack density along with structural integrity. It will only make the vehicles safer, already improving upon the world-class crash safety ratings that Tesla has across its product line.

Now that Model Y vehicles being manufactured at Gigafactory Texas are confirmed to have the Structural Battery Pack and 4680 cells, Tesla’s long-standing projects to revolutionize castings and EV battery tech are here.

Delaware Supreme Court reinstates Elon Musk’s 2018 Tesla CEO pay package

The unanimous decision criticized the prior total rescission as “improper and inequitable,” arguing that it left Musk uncompensated for six years of transformative leadership at Tesla.

The Delaware Supreme Court has overturned a lower court ruling, reinstating Elon Musk’s 2018 compensation package originally valued at $56 billion but now worth approximately $139 billion due to Tesla’s soaring stock price. 

The unanimous decision criticized the prior total rescission as “improper and inequitable,” arguing that it left Musk uncompensated for six years of transformative leadership at Tesla. Musk quickly celebrated the outcome on X, stating that he felt “vindicated.” He also shared his gratitude to TSLA shareholders.

Delaware Supreme Court makes a decision

In a 49-page ruling Friday, the Delaware Supreme Court reversed Chancellor Kathaleen McCormick’s 2024 decision that voided the 2018 package over alleged board conflicts and inadequate shareholder disclosures. The high court acknowledged varying views on liability but agreed rescission was excessive, stating it “leaves Musk uncompensated for his time and efforts over a period of six years.”

The 2018 plan granted Musk options on about 304 million shares upon hitting aggressive milestones, all of which were achieved ahead of time. Shareholders overwhelmingly approved it initially in 2018 and ratified it once again in 2024 after the Delaware lower court struck it down. The case against Musk’s 2018 pay package was filed by plaintiff Richard Tornetta, who held just nine shares when the compensation plan was approved.

A hard-fought victory

As noted in a Reuters report, Tesla’s win avoids a potential $26 billion earnings hit from replacing the award at current prices. Tesla, now Texas-incorporated, had hedged with interim plans, including a November 2025 shareholder-approved package potentially worth $878 billion tied to Robotaxi and Optimus goals and other extremely aggressive operational milestones.

The saga surrounding Elon Musk’s 2018 pay package ultimately damaged Delaware’s corporate appeal, prompting a number of high-profile firms, such as Dropbox, Roblox, Trade Desk, and Coinbase, to follow Tesla’s exodus out of the state. What added more fuel to the issue was the fact that Tornetta’s legal team, following the lower court’s 2024 decision, demanded a fee request of more than $5.1 billion worth of TSLA stock, which was equal to an hourly rate of over $200,000.

Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the autonomous two-seater being reported across social media this week. Based on videos of the vehicle that have been shared online, it appears that Cybercab tests are underway across multiple states.

Recent Cybercab sightings

Reports of Cybercab tests have ramped this week, with a vehicle that looked like a production-ready prototype being spotted at Apple’s Visitor Center in California. The vehicle in this sighting was interesting as it was equipped with a steering wheel. The vehicle also featured some changes to the design of its brake lights.

The Cybercab was also filmed testing at the Fremont factory’s test track, which also seemed to involve a vehicle that looked production-ready. This also seemed to be the case for a Cybercab that was spotted in Austin, Texas, which happened to be undergoing real-world tests. Overall, these sightings suggest that Cybercab testing is fully underway, and the vehicle is really moving towards production.

Production design all but finalized?

Recently, a near-production-ready Cybercab was showcased at Tesla’s Santana Row showroom in San Jose. The vehicle was equipped with frameless windows, dual windshield wipers, powered butterfly door struts, an extended front splitter, an updated lightbar, new wheel covers, and a license plate bracket. Interior updates include redesigned dash/door panels, refined seats with center cupholders, updated carpet, and what appeared to be improved legroom.

There seems to be a pretty good chance that the Cybercab’s design has been all but finalized, at least considering Elon Musk’s comments at the 2025 Annual Shareholder Meeting. During the event, Musk confirmed that the vehicle will enter production around April 2026, and its production targets will be quite ambitious.

Tesla gets a win in Sweden as union withdraws potentially “illegal” blockade

As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.

Swedish union Vision has withdrawn its sympathy blockade against Tesla’s planned service center and showroom in Kalmar. As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal. 

Vision’s decision to pull the blockade

Vision announced the blockade in early December, stating that it was targeting the administrative handling of Tesla’s facility permits in Kalmar municipality. The sympathy measure was expected to start Monday, but was formally withdrawn via documents sent to the Mediation Institute and Kalmar Municipality last week. 

As noted in a Daggers Arbete report, plans for the strike were ultimately pulled after employer group SKR highlighted potential illegality under the Public Employment Act. Vision stressed its continued backing for the Swedish labor model, though Deputy negotiation manager Oskar Pettersson explained that the Vision union and IF Metall made the decision to cancel the planned strike together.

“We will not continue to challenge the regulations,” Petterson said. “The objection was of a technical nature. We made the assessment together with IF Metall that we were not in a position to challenge the legal assessment of whether we could take this particular action against Tesla. Therefore, we chose to revoke the notice itself.”

The SKR’s warning

Petterson also stated that SKR’s technical objection to the Vision union’s planned anti-Tesla strike framed the protest as an unauthorized act. “It was a legal assessment of the situation. Both for us and for IF Metall, it is important to be clear that we stand for the Swedish model. But we should not continue to challenge the regulations and risk getting judgments that lead nowhere in the application of the regulations,” he said.

Vision ultimately canceled its planned blockade against Tesla on December 9. With Vision’s withdrawal, few obstacles remain for Tesla’s long-planned Kalmar site. A foreign electrical firm completed work this fall, and Tesla’s Careers page currently lists a full-time service manager position based there, signaling an imminent opening.
