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.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
