Tesla Semi production rumors swirl as frequent sightings up the ante on expectations
Rumors surrounding the Tesla Semi are plentiful in this day and age, especially as sightings of the company’s commercial vehicle are becoming more frequent. Expectations for the new Semi are high already, and Tesla aims to deliver the truck in a timely fashion after several delays.
The new Semi has been spotted numerous times over the past week, hinting toward ongoing testing before Tesla starts volume production of the massive, all-electric commercial vehicle. Less than two weeks after Tesla’s Q4 2020 Earnings Call, where CEO Elon Musk and others detailed the ongoing offensive to develop the vehicle, the Semi is being spotted by people on public roads. Although Musk stated battery constraint is the hold-up in the Semi’s production, it isn’t stopping the company from testing several new truck builds.
Speculation regarding when Tesla will finally begin volume production is growing, and more rumors surrounding the initial deliveries to pre-orderers appear on what seems like a daily basis. However, the big bottleneck is batteries, and Tesla plans to combat this issue with wide-scale cell production and purchasing. The real question is, how many cells will be “enough?”
EXCLUSIVE: For a few weeks I’ve been in contact with a source from a U.S Tesla supplier. They supply certain parts for the S,X,3 and Y, but I’m here to reveal some info on Tesla Semi. As always, take these kinds of things with a grain of salt. Things/timelines can change.

Elon Musk’s Earnings Call Comments
Musk, who stated last year that it was time for Tesla to enter volume production of the Semi, had a different tune during the Q4 2020 Earnings Call on January 27th. Battery cell constraint is a major bottleneck in starting the Semi production, as fulfilling the number of orders it has would likely inhibit Tesla from being able to produce its mass-market passenger vehicles, like the Model 3 and Model Y.
-
Tesla has recently started producing its own battery cells at a plant that sits adjacent to its main production facility in Fremont, California. Known as the “Kato Road Facility,” Tesla is building its new 4680 cells there, a battery that Tesla claims will cut the cost of its vehicles massively, putting it on a crash course to reach price parity with gas-powered vehicles. The Semi will require significantly more cells than any other Tesla vehicle to date, a problem that the company is aiming to solve by producing its own cells and buying additional ones from third-party suppliers like Panasonic.
Tesla’s 4680 Kato Rd. facility has a top 10 capacity, and it’s not even close to finished
During the Earnings Call, Musk said:
“Prototypes are easy. Scaling production is very hard. So a big part of the reason — the main reason we have not accelerated new products is — like, for example, Tesla Semi is that we simply don’t happen our cells group. We — this — if we were to make the Semi like right now, which we could easily go into production with the Semi, but we would not have enough to cells built for it right now. We will have cells group in ourselves for Semi when we are producing the 4680 volume. But for example, Semi would use typically five times the number of cells that a car would use, but it would not sell for five times what a car would sell for. So it kind of doesn’t make — it would not make sense for us to do the Semi right now, but it will absolutely make sense for us to do it as soon as we can address the cell production constraint. The same would go for that.”
Effectively, Musk explained that it makes more fiscal sense to focus on the mass-market consumer products for right now. When the Kato Rd. Facility begins a massive production of the 4680 cells, Tesla can begin the Semi production efforts, but that doesn’t mean prototypes aren’t on the road now.
New Sightings
Following a sighting by The Kilowatts last week, two new sightings of the Semi have surfaced of the all-white Tesla commercial vehicle.

One video from Cory Draper on YouTube shows a four-and-a-half-minute-long walk around of the Semi, getting a close-up look at the vehicle. One of the most striking features is the size of the power cell, as Draper estimates it is between four and five feet in length. A massive truck requires a massive power source, and the Semi’s sizeable battery storage compartment will drive the truck’s 300 or 500-mile range. Another video from Ivaylo Tzintzarsky shows the power cell from the opposite side.

There are also numerous sensors that can be seen on the Semi, especially in Draper’s video. The top of the windshield is outfitted with at least five sensors that will help with the autonomous driving functionality of the Tesla Semi. Autonomy could help with the evolution of the trucking industry, as many drivers are currently restricted to 11 hours of travel per day, according to the Federal Motor Carrier Safety Administration (FMCSA).
Fuel savings alone could pay for a Tesla Semi, as the company estimates it will save at least $200,000. Combined with superior aerodynamic performance and, a quad-motor powertrain, and a low center of gravity to prevent rollovers, the Tesla Semi has the potential to revolutionize the trucking industry forever. The question is: When will it begin production, and how long until Tesla can produce the 4680 cells in mass quantities to solve the constraint issue?

Tesla Cybertruck production snaps back after ugly supplier fight
Cybertrucks are piling up again at Giga Texas after Tesla’s court win against a parts supplier.
Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.
Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.
Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.
TESLA: U.S. District Judge Christopher R. Wolfe of the U.S. District Court for the Western District of Texas, Waco Division granted Tesla a Temporary Restraining Order and Writ of Replevin in its dispute with Angstrom Automotive (Case No. 6:26-cv-00477).

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.
Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.

Space finally faced the people living next to its next Terafab mega-project
SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.
SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.
The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.
Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.
-
SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.
SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.
Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.
Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
-
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
