Tesla Model Y from Giga Texas will equip Structural Battery Pack, 4680 cells
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.

Tesla officially begins sunset of Model S and Model X
In the latest move to show Tesla is planning to eliminate the Model S and Model X from production, the company’s Korean arm has officially set a firm cutoff date of March 31, 2026, for new orders of both models.
Tesla has officially started its process of sunsetting the Model S and Model X just months after the company confirmed it would stop producing the two flagship vehicles in 2026.
This step marks the end of an era for the vehicles that helped establish not only Tesla’s prowess as an automaker but also its status as a disruptor in the entire car industry. While these two cars have done a tremendous amount for Tesla, the signal that it is time to wind down their production has evidently arrived.
In the latest move to show Tesla is planning to eliminate the Model S and Model X from production, the company’s Korean arm has officially set a firm cutoff date of March 31, 2026, for new orders of both models.
This is the first time Tesla has announced a hard global deadline for the Model S and X, as after that date, only existing inventory will be available in South Korea.
The move to bring closure to the Model S and Model X aligns with CEO Elon Musk’s plans for Tesla moving forward. During the Q4 2025 Earnings Call in January, Musk said the two cars deserved an “honorable discharge” for what they have done for the company.
The long-running programs are primarily being removed so that manufacturing lines can be repurposed for high-volume manufacturing of the Optimus humanoid robot. Tesla is targeting a production rate of up to one million units each year.
The Model S and Model X being removed from Tesla’s plans is a tough choice, but it was one that was written on the wall. Sales of these premium models have declined sharply in recent years, and even with Plaid configurations that are performance-forward, the company still has had trouble getting them sold.
In 2025, the Model S and Model X together accounted for roughly 3 percent of Tesla’s global deliveries, down significantly from prior periods as competition intensified in the luxury EV segment and buyers shifted toward more affordable options like the Model 3 and Model Y.
The Model S saw sales drop over 50 percent year-over-year in some quarters, while the Model X faced similar pressures from rivals, including the Rivian R1S and BMW iX.
Despite their dwindling volume, the Model S and Model X remain technological showcases. The Plaid variants deliver blistering acceleration, advanced Full Self-Driving capability, and luxurious interiors.
The phase-out paves the way for Tesla’s strategic pivot toward autonomy, robotics, and higher-volume vehicles.
Tesla brings closure to flagship ‘sentimental’ models, Musk confirms
Fremont will continue producing the refreshed Model 3 and Model Y, ensuring the factory remains a key automotive hub while expanding into robotics. Tesla has stated that the shift is not expected to result in job losses and could increase headcount as Optimus production ramps up.
For Tesla fans, the sunset represents a bittersweet moment. The Model S, introduced in 2012, proved EVs could compete with luxury sedans, while the Falcon-wing-door Model X set new standards for family haulers. Owners can expect continued software support and service for years to come.
Many fans have pushed for the Model X to hang around due to its appeal for families.
With the two cars heading out, Tesla’s priority now becomes its future products, especially that of the Optimus robot, which is the main reason for the S/X platform’s conclusion.

Tesla shows off mysterious vehicle at Giga Texas
The mysterious structure, partially unboxed amid construction materials, has sparked widespread speculation among Tesla enthusiasts and analysts. Many are convinced it is the long-rumored Model Y L, the extended-wheelbase variant already popular in China, now arriving in Texas for potential U.S. production.
Tesla seemingly showed off a mysterious vehicle at Giga Texas, one that seems to be completely different than anything the company currently makes for the U.S. market.
The vehicle, which was spotted on the plant’s property, appears to be similar to the Model Y L that has not yet launched in North America, and is currently built at Gigafactory Shanghai in China.
Drone pilot Joe Tegtmeyer captured intriguing footage at Tesla’s Giga Texas on March 23, 2026, revealing what appears to be a large, blue plastic-wrapped vehicle body resting inside a wooden shipping crate outdoors.
Well this is interesting at Giga Texas today … what do YOU think this is? 🤔😎 pic.twitter.com/U9pLvqbf7L

The mysterious structure, partially unboxed amid construction materials, has sparked widespread speculation among Tesla enthusiasts and analysts. Many are convinced it is the long-rumored Model Y L, the extended-wheelbase variant already popular in China, now arriving in Texas for potential U.S. production.
The images show an elongated silhouette that stands out from standard Model Y bodies. Side-by-side comparisons shared in replies to Tegtmeyer’s post highlight key differences: the rear door extends farther over the wheel arch than on a regular Model Y, and the rear glass appears to run all the way to the spoiler lip without the metal trim seen on shorter versions.
One overlay analysis noted that the visible proportions align precisely with the Chinese-market Model Y L, which measures approximately 4.98 meters long with a 3.04-meter wheelbase, which is about seven inches longer overall than the standard Model Y sold in the U.S.

The vehicle is a bare “body-in-white” shell, typical of prototypes sent abroad for tooling validation and local manufacturing ramp-up. Tesla has already launched the six- and seven-seat Model Y L in China and other markets, where it offers roughly 10% more cargo space and greater family-friendly versatility.
This sighting fits Tesla’s broader strategy. Industry observers expect the company to localize Model Y L production at Giga Texas by mid-2026 to serve American families seeking extra room without stepping up to the larger Cybertruck or a future full-size SUV.
Bringing the design stateside could add tens of thousands of annual deliveries while leveraging existing Model Y lines. People have been adamant that they want the Model Y L in the U.S., especially as Tesla plans to fade the Model X, the company’s most ideal vehicle for large families, out of production in the near future.
Tesla Model Y lineup expansion signals an uncomfortable reality for consumers
While Tesla has made no official comment, the timing, amid Giga Texas expansion and steady Model Y output, suggests the mysterious crate is more than a random prototype.
If confirmed as the Model Y L, it marks another step in Tesla’s effort to refresh its bestselling SUV for global demand. The vehicle would perform exceptionally well in the U.S., and despite the company’s rather mute stance on bringing it to America, this might be the biggest hint to date that it could be on the way.

Tesla Cybertruck just won a rare and elusive crash safety honor
Only the most outstanding of performances in crash tests can warrant an IIHS Top Safety Pick+ award, as vehicles listed with that ranking must achieve “Good” ratings in the small overlap front, updated side, and updated moderate overlap front tests, along with “Acceptable” or “Good” headlights standard on all trims.
Tesla Cybertruck landed a rare and elusive safety honor from the Insurance Institute for Highway Safety (IIHS). It was the only pickup truck in the U.S. market to do so.
The IIHS rewarded the Cybertruck with the Top Safety Pick+ honors, the highest marks a vehicle can receive from the agency.

Cybertruck was the only truck to also win an NHTSA Five-Star Safety rating, making it the only pickup available on the market to be recognized with top marks from both agencies.
There are a multitude of options for pickups in the U.S. market, as it is one of the most popular vehicle types for consumers in the country. Pickups are great vehicles for anyone who does any sort of hauling or is just looking for extra space for any variety of reasons.
Pickups are also inherently safer than other body types on the road, mostly because they are larger and heavier, making them more favorable against other vehicle types in the event of a collision. However, Tesla has a significant advantage in safety with its vehicles because it engineers them to not only be safer in collisions, but also easier to repair.
The Cybertruck managed to achieve “Good” ratings, the highest marks available by the IIHS, in all three Crashworthiness categories, as well as “Good” ratings in both Crash Avoidance and Mitigation assessments.
It also received “Good” ratings across all driver and pedestrian crash-test performance metrics, except for one, where it earned an “Acceptable” rating for rear passengers in the Chest category.
The Cybertruck’s outstanding crash test performance has won it this incredible mark as the pickup still tends to be one of the more polarizing vehicle designs on the market.
It is no secret that Tesla has struggled with demand of the Cybertruck due to pricing, but the recent rollout of a trim that was temporarily priced at just $59,990 showed plenty of people want the all-electric pickup.
