SpaceX’s South Texas Starship factory prepares for major upgrades
In what is probably a sign of things to come for SpaceX’s nascent Florida Starship factory, the company’s original Starbase facility in South Texas may be about to graduate from tents to more permanent buildings.
More than two years ago, in late 2019, SpaceX followed in the footsteps of Tesla and began constructing a surprisingly advanced factory out of a series of tents. Instead of Model 3s, though, SpaceX would be building and assembling sections of the largest and most powerful rocket ever built. Measuring approximately 120 meters (~390 ft) tall, 9 meters (~30 ft) wide, ~5000 tons (~11M lb) fully fueled, and capable of producing around 7500 tons (~16.5M lbf) of thrust at liftoff, Starship is a fully reusable rocket that aims to perfect what SpaceX has already achieved with partially reusable Falcon 9s and Heavies.
Nonetheless, Starship manufacturing represents a substantial departure from the methods SpaceX uses to build Falcon rockets.
Instead of heavily leaning on horizontal integration (meaning that the rockets are primarily assembled in a horizontal orientation), Starship and its Super Heavy booster are almost exclusively assembled vertically. Excluding the machining of major loadbearing structures, Starship manufacturing generally begins with giant rolls of thin (3-4mm or ~0.15 in) stainless steel. SpaceX uses a custom tool to unspool the sheet metal, cuts off a roughly 28-meter (~92 ft) long strip, and then welds the ends of that strip together to produce a cylindrical barrel. Repeat that process 57 times and you end up with enough rings to assemble a full Super Heavy booster and most of a Starship.
However, using increasingly custom tools, SpaceX first stacks and welds those individual rings together to form sections of two, three, four, or five. Each section is then prepared for its specific role with a range of cutouts, plumbing, reinforcements (vertical stringers or circumferential stiffeners), thrust structures (the plates that Raptor engines attach to), and other add-ons. Most importantly, certain stacks of rings are mated with large steel domes – welded together out of prefabricated steel plates – to form forward, common, and aft dome sections. For Starship, SpaceX also assembles the ship’s conical nose section in a similar manner.
Virtually all ring, dome, and nose assembly work is conducted in one of three massive tents – each about 114m x 35m (375′ x 110′) – that form the backbone of Starbase’s Starship factory. Finally, SpaceX has built a series of massive open-air bays where, once fully outfitted, each ship and booster section is stacked in a specific order and welded together to complete the basic structures of Starship and Super Heavy.
While SpaceX continues to speed towards the completion of Starbase’s largest and tallest Starship assembly bay yet, the latest news centers around Starbase’s tents. After physically relocating a smaller but still substantial tent believed to be used basic metalwork (laser/water cutting, presses, etc.), SpaceX has rapidly broken ground and partially completed the foundation of a massive, new building believed to be the start of an upgraded Starship factory.
-->According to RGV Aerial Photography, SpaceX isn’t merely expanding the main three-tent factory with a fourth larger, permanent building. Instead, it reportedly aims to replace all of Starbase’s tents with a single 300,000-square-foot (~28,000 square meter) building that will be about 18 meters (60 ft) tall and likely measure around 800 feet (250m) long and 400 feet (120m) wide. Starbase’s tents are roughly the same height but their tented roofs mean that only a fraction of that height can be used for ring work and only a fraction of the floor space for taller nose work.
In comparison, a 300,000 square-foot building would have almost two and half times as much covered floor space as Starbase’s three tents – all of which can theoretically be used for ring and nose section assembly. In fact, with a mostly flat 18-meter roof, SpaceX could feasibly expand most ‘stacks’ by a ring or two, which would reduce the number of sections (and thus stacking operations) needed to assemble a ship or booster.
All told, while tents (“sprung structures”) can clearly be indefinite solutions for things like automotive manufacturing, Starship production is one case in which a more permanent flat-ceiling building is undeniably superior. With more than two years of experience and data to draw from, SpaceX may finally be confident enough in its present-day Starship production methods to commit to the construction of Starbase’s next evolution. Stay tuned to see where it leads.

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.
