Tesla CEO Elon Musk disclosed some details about the electric automaker’s 4680 cell plant last week. After stating that the facility is “probably in the top 10 battery cell factories on Earth despite being a pilot plant,” speculation began about how massive Tesla’s new facility that sits just across the street from the Fremont production facility is. Although it is in the top 10, it’s not even close to finished.

Tesla’s introduction of the 4680 battery cell came in September 2020 at the Battery Day event. Musk and others outlined the company’s roadmap for global EV dominance through the most important part of an electric car: the cell. The new cell has 500% more energy, six times the power of the old 2170 cells, and also offers dramatic range increases for more drive time between charges. It was truly revolutionary because Tesla is already the most notable company in electric cars.

With a considerable lead in the EV sector, Tesla was effectively announcing, “eat our (sustainable) dust” after showing the new 4680 cells. Some were skeptical, believing that the new cell wouldn’t be available for some time. Musk immediately silenced those doubts, indicating that the new cells had been deployed in working vehicles for months.

The point is, the Kato Road facility, as it is widely known as, is one of the largest facilities in the world. While we are not sure what the current capacity is, if it is a top 10 facility in terms of capacity, we can speculate how big it may be.

According to Argus Media, the 10 largest battery cell plants range from 24 GWh per year to 70 GWh per year. The largest, an LG Chem facility in Wroclaw, Poland, has the 70 GWh capacity, leading BYD’s Qinghai, China plant by 10 GWh. Tesla and Panasonic’s joint venture at Gigafactory 1 in Nevada is a 35 GWh per year facility, making it the fifth-largest plant globally.

Because Tesla’s Kato Road facility is a pilot plant, we can likely assume that it is within the bottom half of this list. Especially with Gigafactory 1 being the fifth-largest, it is very likely that Kato Road is simply not producing as many cells or as much battery capacity as Giga 1, but it’s not to say that this won’t happen. The issue is that Tesla is still battery constrained, even with a large-scale facility in Nevada and with several third-party manufacturers pumping cells to the automaker at a massive rate. Kato Road will contribute to the solution to the constrained problem, and the facility will likely be significantly larger than Giga 1, considering the projects that Tesla plans to fulfill with the 4680 cells, the largest being the Tesla Semi.

The Semi is still not ready for production, Musk said on the Q4 Earnings Call last week. “We will have cells group in ourselves for Semi when we were 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,” Musk said. The issue is cell availability, and since the Semi is going to equip Tesla’s newest 4680 project, it is safe to assume that Kato Road still has some expanding to do. If it is already a top 10 facility, yet it is still not ready to take on the massive Semi task, along with all of the other vehicles it will eventually fulfill, Kato Road may become a top 3 facility.

Ultimately, Tesla requires more cells. With no plans to eliminate purchases from third-party suppliers in the near-term, Tesla wants to increase purchases from those suppliers. CATL, Panasonic, and LG Chem could supply Tesla with more batteries moving forward, even with the Kato Road facility’s expansion and ramping up. The fact is, Tesla isn’t done solving the battery constraint issue, and it could battle with it for years to come. However, it won’t stop production from increasing because more cells are becoming available almost every day through supplier deals, increased outputs, and in-house manufacturing advancements, all of which make Tesla the company to beat for the foreseeable future.

Starlink is ‘biggest competitive advantage,’ but it’s temporary, United CEO says

United Airlines CEO Scott Kirby said that SpaceX’s Starlink satellite internet is its leading competitive advantage in the U.S. airline industry. However, in recent comments, while he described the service as “the biggest competitive advantage” the carrier currently holds, he also acknowledged that the edge is temporary.

“…everybody eventually is going to have high-speed low earth orbit internet connectivity. It’s going to be a must-have. We are going to have a few years of being the only airline that has it at scale, and that’s our mission,” Kirby said. Until everyone has it, United aims to capitalize on its head start by converting trial users into long-term loyal customers.

United has moved faster than its rivals on Starlink installations. As of mid-to-late October 2026, the system was on roughly 43 percent of its fleet, with plans to reach 61 percent by year-end, 87 percent by June 2027, and full fleet coverage by the end of next year.

The airline already operates more Starlink-equipped flights than the rest of the U.S. industry combined. Los Angeles International Airport is scheduled to become United’s first 100 percent Starlink hub in the first half of 2027, and the carrier’s app will display the likelihood that any given flight has the service.

Kirby has pointed to early evidence that the offering influences booking decisions. Some passengers loyal to other airlines are already switching flights for Starlink connectivity, something the airline, along with American Airlines, has tried to leverage against competing airlines. Both companies used status-match programs, and some of those customers are pursuing company-specific credit cards, which signals an intent to stay.

Once onboard, these customers encounter the airline’s broader investments in aircraft, larger seat-back screens, oversized bins, connection tools, and a mobile app that Kirby says outperforms competitors. Wi-Fi satisfaction scores on Starlink-equipped planes have been reported to be nearly double those on aircraft with other systems.

Competitors are moving slowly to do the same. Southwest Airlines began installations in 2025 and expects to complete them soon. Delta is pursuing Amazon’s Leo system, while American expects to start Starlink work in early 2027 and has not yet detailed regional-fleet plans. This timeline gap gives United a multi-year window in which it remains the only major U.S. carrier offering Starlink at scale.

Kirby has framed the strategy as pressing that advantage while simultaneously widening gaps in other technology areas so that customers who try United for the Wi-Fi remain for the overall experience.

The approach reflects a calculated bet that superior in-flight connectivity can accelerate share gains and support longer-term financial targets, including a 10 percent pre-tax margin goal.

High-speed internet is particularly valued by premium and business travelers who can work or stream reliably. As low-Earth-orbit service becomes ubiquitous, the temporary nature of the pure connectivity edge means United’s retention will depend on whether its other product and operational improvements keep pace.

Tesla Cybercab’s unorthodox paint process explained

Published

Tesla Cybercab skips the traditional paint shop entirely, marking an unorthodox process for coloring the fully autonomous vehicle. However, the decision was a smart one, as it slashed factory costs, floor space utilization, and complexity, since Tesla relied on specialized alloys and in-mold coloring.

Munro Live was given the opportunity to do a factory walkthrough with Tesla Vice President of Vehicle Engineering Lars Moravy, who explained and detailed how Cybercab production at Giga Texas eliminates one of the automotive manufacturing industry’s most expensive and space-hungry elements.

A conventional paint line can cost hundreds of millions of dollars and require a million man-hours to build. Moravy framed the choice around Tesla’s core rule: “Question the requirements: why do you need paint?”

The structural answer lies in material selection. The aluminum alloys used in Cybercab’s front and rear castings do not oxidize and lose strength over time, the way many common automotive aluminum alloys do. Only the side modules, built around hot-stamped boron-steel door rings, receive an anti-corrosion e-coat, or dip coat. Front and rear modules skip coating altogether.

Model Y and Model 3 bodies, by contrast, are fully coated and painted.

Exterior colors come from the plastics shop, which Tesla engineers described as “our paint shop” for the Cybercab. Body panels are produced via reaction injection molding, referred to as RIM. Color is then mixed into a polyurethane resin at the mix head immediately before injection, so the panel emerges already colored with a Class-A surface.

Robots trim overflow to control sink marks and flow lines. The process avoids conventional spray-paint defects like orange peel and paint bleed. Scratches can still be repaired with compatible coatings that behave “basically like paint.” Because color is integral rather than a surface layer, shallow scratches do not expose a contrasting undercoat.

The secret behind Tesla’s Cybercab Gold goes well beyond just the color

Tesla has also explored related approaches, including in-mold lamination and painted films on stamped panels.

The manufacturing payoff is substantial because removing the paint shop, combined with the “unboxed” modular process that builds and tests front, rear, side, and center modules in parallel before a short final assembly, cuts factory floor space per vehicle by about 50 percent.

Final assembly itself uses only about 25 automated stations, far fewer than the typical Model Y line, and the overall line runs at about 78 percent automation, Moravy said. The approach also eliminates volatile organic compound emissions associated with traditional spray painting for these panels and shortens the coloring cycle from hours to minutes.

Cybercab’s paint strategy is clearly less about aesthetics than about systematically deleting capital-intensive, energy-heavy, and space-consuming steps once material science and process design make them unnecessary. It is a concrete example of Tesla applying first-principles questioning to one of the auto industry’s most entrenched factory requirements.

Tesla has a Cybercab problem nobody saw coming

Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.

Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”

Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.

The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.

Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.

The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.

Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”
