SpaceX borrows Tesla's tent factory strategy for new Starship production HQ
Confirmed yesterday morning by CEO Elon Musk, SpaceX has copied Tesla’s approach to factory expansion and is building a giant tent to upgrade its South Texas Starship production facilities.
A big step towards more traditional aerospace-style manufacturing facilities, SpaceX has contracted the same company used by Tesla to create a fourth general assembly line (GA4) in a giant tent outside its Fremont, CA factory in 2018. Instead of Model 3s, however, Sprung Instant Structures (Sprung for short) is rapidly raising a large tent that will eventually allow SpaceX to fabricate and weld more Starship parts and sections in an enclosed environment, an improvement from the current practice of building prototypes out in the harsh environment of coastal Texas.
In typical fashion, Musk believes that the new enclosed production facilities – just a collection of shipping crates as of December 18th – could be ready to begin manufacturing Starship parts as early as next month, and the progress Sprung has made makes it unusually hard to fault his optimism.
Likely taken in mid-December, aerial photos taken by pilot and photographer Sam Sun help sketch out a rough view of the prospective Starship factory. SpaceX appears to have almost entirely foregone a concrete foundation for the new tent, instead opting for lines of steel shipping containers that likely add a bit of height at the cost of structural stability.

According to figures printed right on one of Sprung Structures’ many shipments of materials, the initial building will measure approximately 45 meters (150 ft) wide, 77 meters (255 ft) long, and 18 meters (60 ft) tall. While Tesla’s GA4 tent is the same width and (mostly) height, it’s an impressive 280 meters (915 ft) long – almost four times bigger than SpaceX’s newest Boca Chica addition.
-->While the shipping container foundation is definitely a bit of a risk a mile from the Gulf of Mexico, it does mean that SpaceX might actually be able to move the shell of its new Starship factory if the need arises. SpaceX is in the midst of expanding its Boca Chica lots, potentially giving the company a lot more space to grow its enclosed factory down the road. The simplest possible expansion available would basically double the length of the existing structure, making it more like 150-180 meters (500-600 ft) long.
Regardless, even the current 150′ x 255′ enclosure will end up offering more than 38,000 ft² (3500 m²) of factory space once finished. Depending on what its primary purpose is, SpaceX could probably fit 5-8 stacks of 5-6 rings each (10-11m tall) down the center of the tent, with room for maybe 10-24 additional stacks of 2-3+ rings (3.5-5m tall) in the space remaining. The middle line of hypothetical rings could produce the entire barrel section of 1-2 Starships simultaneously, leaving perhaps 3-4 large sections to be welded together out in the elements or at SpaceX’s new wedge-shaped windbreak.
Of course, the facility will likely end up being mixed-use, potentially offering enough space to simultaneous fabricate all subsections of a single Starship prototype before they are assembled elsewhere.
Ultimately, Sprung is now in the process of installing a large quantity of insulation inside the tent’s walls, indicating that SpaceX’s South Texas welding crew may soon be blessed with a climate-controlled work environment. Meanwhile, SpaceX CEO Elon Musk believes that Boca Chica’s new tent could be complete and ready to begin building Starship hardware as soon as January 2020, while he says that the next Starship prototype – now known as Starship SN01 (serial number 01) – could be ready for flight testing just one or two months after that.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
