New Tesla Gigafactory projects revealed through latest building permits
Teslarati has learned that the total value of all building permits issued for the Tesla Gigafactory now stands at $386 million, or $63 million more than the last time Jack Cookson of BuildZoom checked in with the local building inspector’s office.
Perhaps the most surprising bit of information is that a permit was issued recently for a “temporary tent structure” for a “special event” costing $300,000 likely to be used for the Gigafactory Grand Opening party. We recently spotted the massive tent, the size of two NBA basketball courts, in newly captured aerial photos of the Gigafactory.

“Section F Expansion” assumed to be one of the two new additions at the battery plant claimed the largest single permit by dollar at $22 million. There was also a permit issued for “seismic anchoring” totaling $9.4 million. Presumably, seismic anchoring is part of the foundation work for Section F.
We have to keep reminding ourselves that the current building represents less than 15% of the total size of the Gigafactory when finished. All the exterior walls except the main wall in front are temporary, designed to be broken through as new sections are added.
We’ve provided all of the notable permits filed for the Tesla Gigafactory via BuildZoom.
- The total value of work since we last checked in has been 63 million dollars, bringing the total for the entire project to 386 million dollars.
- First, and perhaps most relevant to the opening, is on July 18th Tesla filed a permit for a “temporary tent structure” for a “special event”. While I can’t be sure, the $300,000 tent might be for the grand opening.
- The biggest single permit was a 22 million dollar permit for the “Section F Expansion”.
- The first permits related to Panasonic work were issued to Tesla on June 28th and July 13th. The two permits are for the installation of Panasonic tools. The two permits were both designated to section B/C and totaled 16.2 million dollars.
- There was also 14.4 million dollars worth of addenda to sections D/E.
- There was 9.4 million dollars in seismic anchoring issued in permits.
- There was 350,000 dollars across two permits for contractor lunch tents, perhaps related to the increase in construction workers they recently took on.
- There was also a parking expansion and while I don’t know what a “Nitrogen Yard” is there was a permit for one.
As Panasonic executive vice president Yoshihiko Yamada explained at the Tuesday news conference, his company is fully committed to its partnership with Tesla. Panasonic took out two building permits of its own recently, both covering the installation of its proprietary machines and tools in sections B and C. The two permits together total $16.2 million.
The local building inspector’s office also recorded permits totaling $14.4 million for additional work in Sections D and E and $9.4 million in other miscellaneous work recently. They include an expansion to the parking area. Tesla made sure there was parking for 2,000 cars in time for the grand opening this weekend.
-->The pace of construction at the Gigafactory is accelerating. Workers are now busy seven days a week, working two shifts a day. In order to accommodate their needs, Tesla has applied for permits for two contractor lunch tents worth a total of $350,000.
Finally, Jack Cookson reports a permit application for a “Nitrogen Yard.” Exactly what that is or what role it will play in the production process remains unclear.

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.
