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 is hiring an Autopilot Test Engineer in Shanghai, a move that signals continued groundwork for the validation of Full Self-Driving (FSD) in China. The role is based in Lingang, the district that houses Gigafactory Shanghai and has become a key testing zone for advanced autonomous features.

As observed by Tesla watchers, local authorities in Shanghai’s Nanhui New City within Lingang have previously authorized a fleet of Teslas to run advanced driving tests on public roads. This marked one of the first instances where foreign automakers were permitted to test autonomous driving systems under real traffic conditions in China. 

Tesla’s hiring efforts come amid ongoing groundwork for a full FSD rollout in China. Earlier reporting noted that Tesla China has been actively preparing the regulatory and infrastructure foundation needed for full FSD deployment, even though the company has not yet announced a firm launch date for the feature in the market.

As per recent comments from Tesla China Vice President Grace Tao, the electric vehicle maker has been busy setting up the necessary facilities to support FSD’s full rollout in the country. In a comment to local media, Tao stated that FSD should demonstrate a level of performance that could surpass human drivers once it is fully rolled out.

“We have set up a local training center in China specifically to handle this adaptation,” Tao said. “Once officially released, it will demonstrate a level of performance that is no less than, and may even surpass, that of local drivers.”

Tesla CEO Elon Musk has been quite bullish about a potential FSD rollout in China. During the 2025 Annual Shareholder Meeting, Musk emphasized that FSD had only received “partial approval” in China, though full authorization could potentially arrive around February or March 2026. This timeline was reiterated by the CEO during his appearance at the World Economic Forum in Davos.

Tesla Model Y outsells all EV rivals in Europe in 2025 despite headwinds

The result highlights the Model Y’s continued strength in the region.

The Tesla Model Y was Europe’s most popular electric car in 2025, leading all EV models by a wide margin despite a year marked by production transition, intensifying competition, and anti-Elon Musk sentiments. 

The result highlights the Model Y’s continued strength in the region even as Volkswagen overtook Tesla as the top-selling EV brand overall.

As per data compiled by JATO Dynamics and reported by Swedish outlet Allt om Elbil, the Tesla Model Y recorded 149,805 registrations across Europe in 2025. That figure placed it comfortably at No. 1 among all electric car models in the region.

The Model Y’s performance in Europe is particularly notable given that registrations declined 28% year-over-year. The dip coincided with Tesla’s Q1 2025 transition to the updated Model Y, a changeover that temporarily affected output and deliveries in several markets. Anti-Elon Musk sentiments also spread across several European countries amidst the CEO’s work with U.S. President Donald Trump.

Even with these disruptions, the Model Y outsold its nearest rival by more than 50,000 units. Second place went to the newly launched Skoda Elroq with 93,870 registrations, followed by the Tesla Model 3 at 85,393 units. The Model 3 also recorded a 24% year-over-year decline. Renault’s new electric Renault 5 placed fourth with 85,101 registrations.

Other top performers included the Volkswagen ID.4, ID.3, and ID.7, along with the BMW iX1 and Kia EV3, many of which posted triple-digit growth from partial-year launches in 2024.

While the Model Y dominated individual model rankings, Volkswagen overtook Tesla as Europe’s top EV brand in 2025. Volkswagen delivered 274,278 electric cars in the region, a 56% increase compared to 2024. Much of that growth was driven by the Volkswagen ID.7. Tesla, by contrast, sold 236,357 electric vehicles in Europe, representing a 27% year-over-year decline.

JATO Dynamics noted that “Tesla’s small and aging model range faces fierce competition in Europe, both from traditional European automakers and a growing number of Chinese competitors.”

Despite intensifying competition and brand-level shifts, however. the Model Y’s commanding lead demonstrates that Tesla’s bestselling crossover remains a dominant force in Europe’s fast-evolving EV landscape.

SpaceX’s Starlink, the satellite internet program launched by Elon Musk’s company, has gotten its latest airline adoptee, offering stable and reliable internet to passengers.

Southwest Airlines announced on Wednesday that it would enable Starlink on its aircraft, a new strategy that will expand to more than 300 planes by the end of the year.

The company said it plans to “rapidly integrate Starlink into its fleet,” and that the first Starlink-equipped aircraft will enter service this Summer.

Tony Roach, Executive Vice President, Chief Customer and Brand Officer for the airline, said:

“Free WiFi has been a huge hit with our Rapid Rewards Members, and we know our Customers expect seamless connectivity across all their devices when they travel. Starlink delivers that at-home experience in the air, giving Customers the ability to stream their favorite shows from any platform, watch live sports, download music, play games, work, and connect with loved ones from takeoff to landing.”

Southwest also said that this is just one of the latest upgrades it is making to provide a more well-rounded experience to its aircraft. In addition to Starlink, it is updating cabin designs, offering more legroom, and installing in-seat power to all passengers.

Southwest became one of several airlines to cross over to Starlink, as reviews for the internet provider have raved about reliability and speed. Over the past year, Hawaiian Airlines, United Airlines, Alaska Airlines, airBaltic, Air France, JSX, Emirates, British Airways, and others have all decided to install Starlink on their planes.

This has been a major move away from unpredictable and commonly unreliable WiFi offerings on planes. Starlink has been more reliable and has provided more stable connections for those using their travel time for leisure or business.

Jason Fritch, VP of Starlink Enterprise Sales at SpaceX, said:

“We’re thrilled to deliver a connectivity experience to Southwest Airlines and its Customers that really is similar, if not better, than what you can experience in your own home. Starlink is the future of connected travel, making every journey faster, smoother, and infinitely more enjoyable.”

Starlink recently crossed a massive milestone of over 10 million subscribers.
