Tesla poised to streamline China’s Model Y production with next-gen casting machine
It appears that Tesla China is making the necessary preparations to adopt a streamlined production process for the Model Y, and perhaps even the Model 3, in Gigafactory Shanghai. Signs of such a strategy was recently revealed in a drone flyover from Tesla enthusiast Wuwa Vision, who was able to capture images of an extension to the Phase 1 building’s body stamping area.
The tail end of Gigafactory Shanghai Phase 1 is widely considered to be allotted for body stamping activities. The section was completed together with the rest of the Phase 1 building last year before the construction of the Phase 1.5 zone (a battery and powertrain assembly facility) started. Interestingly enough, the recent drone flyover shows that workers are now expanding the body stamping area.
What’s more, the construction in the body stamping workshop involves what appeared to be deep excavations, suggesting that the area will be hosting a large machine, or at least one that is larger than the ones used in the existing Model 3 line. Patents from Tesla and statements from CEO Elon Musk have hinted at such a process—one that can very well revolutionize the Model Y’s production in China.
Interestingly enough, the massive casting machine seems to be going to the Phase 1 building, which is widely believed to be allotted only for the Model 3. The reasons behind his have not been revealed by Tesla, though it’s plausible that the new casting machine may also be used for the Model 3’s production. Otherwise, this could suggest that the Model Y may begin production in the Phase 1 area, at least until Phase 2A is complete. Such a strategy would allow Tesla to start producing the crossover despite the second phase of Gigafactory 3’s buildout still ongoing.
Last July, a patent application from Tesla was published that pointed to the utilization of a giant casting machine for the production of electric vehicles. The new casting machine will feature a central hub to receive several dies that are then assembled into specific portions of a vehicle frame before being cast. The patent, in a way, reflected Elon Musk’s comments during his appearance at the Ride the Lightning podcast, where he discussed some of the manufacturing improvements in the Model Y.
“There are some manufacturing improvements for the [Model] Y. The rear underbody we’re moving to an aluminum…casting instead of a series of stamped steel and aluminum pieces. When we get the big casting machine, it’ll go from 70 parts to 1 with a significant reduction in capital expenditure on all the robots to put those parts together,” Musk said.
Musk has mentioned this large casting machine multiple times, including in his recent appearance at the Third Row Podcast, where he mentioned that the idea was amusingly inspired by a diecast Tesla Model S on his desk. Speaking about his thought process, Musk noted that he thought the Model S diecast “doesn’t cost much, and it looks pretty detailed.” Thus, he thought that it might be a good idea to “make this bigger.”
The Model Y’s giant casting machine and its results have been teased in the ongoing teardown of the vehicle from automotive veteran Sandy Munro. Compared to the Model 3, the Model Y’s casts are larger, and the body of the car seems far more refined. With such a system in place, Tesla would be able to produce the Model Y in a faster, more efficient manner. This is extremely valuable for Tesla, since the Model Y is poised to be its most high-volume vehicle yet, with Musk stating that the crossover would likely outsell the Model S, Model X, and Model 3 combined.
Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
