Tesla’s 4680 Kato Rd. facility has a top 10 capacity, and it’s not even close to finished
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.

Tesla’s $2.9 billion bet: Why Elon Musk is turning to China to build America’s solar future
Tesla looks to bring solar manufacturing to the US, with latest $2.9 billion bet to acquire Chinese solar equipment.
Tesla is reportedly in talks to purchase $2.9 billion worth of solar manufacturing equipment from a group of Chinese suppliers, including Suzhou Maxwell Technologies, which is the world’s largest producer of screen-printing equipment used in solar cell production. According to Reuters sources, the equipment is expected to be delivered before autumn and shipped to Texas, where Tesla plans to anchor its next phase of domestic solar production.
The move is a direct extension of a vision Elon Musk has been building for months. At the World Economic Forum in Davos this past January, Musk announced that both Tesla and SpaceX were independently working to establish 100 gigawatts of annual solar manufacturing capacity inside the United States. Days later, on Tesla’s Q4 2025 earnings call, he made the ambition concrete: “We’re going to work toward getting 100 GW a year of solar cell production, integrating across the entire supply chain from raw materials all the way to finished solar panels.”
Job postings on Tesla’s website reflect that same target, with language explicitly calling for 100 GW of “solar manufacturing from raw materials on American soil before the end of 2028.”
The urgency behind the latest solar manufacturing target is rooted in a set of rapidly emerging pressures related to AI and Tesla’s own energy business. U.S. power consumption hit its second consecutive record high in 2025 and is projected to climb further through 2026 and 2027, driven largely by the explosion in AI data centers and the broader electrification of transportation. Tesla’s own energy division, which produces the Megapack utility-scale battery storage system, has been growing rapidly, and solar supply is a critical companion component for the business to scale. Musk has argued that solar is not just a clean energy option but the only one that makes economic sense at the scale AI infrastructure demands.

Ironically, the path to domestic solar independence currently runs through China. Sort of.
Despite Tesla’s stated push to localize its supply chain, mirrored recently by the company’s plan for a $4.3 billion LFP battery manufacturing partnership with LG Energy Solution in Michigan, Tesla still relies on China-based suppliers to keep its cost structure intact.
The $2.9 billion equipment deal underscores a tension Musk himself acknowledged at Davos: “Unfortunately, in the U.S. the tariff barriers for solar are extremely high and that makes the economics of deploying solar artificially high, because China makes almost all the solar.” Building the factory in America requires buying the machinery from the country Tesla is trying to reduce its dependence on.

The regulatory pathway adds another layer of complexity. Suzhou Maxwell has been seeking export approval from China’s commerce ministry, and it remains unclear how quickly that clearance will come. Still, the market has already reacted, with shares in the Chinese firms reportedly involved in the talks surged more than 7% following the Reuters report that broke the story.
Whether Tesla can hit its 2028 target of 100GW of solar manufacturing remains an open question. Though that scale may seem staggering, especially in such a short timeframe, we know that Musk has a documented history of “always pulling it off” in the face of ambitious deadlines that may slip. But, rest assured – it’ll get done.

Elon Musk reveals date of Tesla Full Self-Driving’s next massive release
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla CEO Elon Musk revealed the date of Full Self-Driving’s next massive release: v14.3.
For months, Tesla owners with Hardware 4 have been utilizing Full Self-Driving v14.2 and subsequent releases. Currently, the most up-to-date FSD version is v14.2.2.5, which has definitely brought out mixed reviews. With releases, some things get better, and other things might regress slightly.
For the most part, things are better in terms of overall behavior.
However, many owners have been looking forward to the next release, which is v14.3, about which Musk has said many great things. Back in November, Musk said that v14.3 “is where the last big piece of the puzzle lands.”
He added:
“We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla Full Self-Driving v14.2 is a considerable improvement from early versions of the suite, but we have written about the somewhat confusing updates that have come with recent versions.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
They’ve been incredibly difficult to gauge in terms of progress because some things have gotten better, but there seems to be some real regression on a handful of things, especially with confidence and assertiveness.
Musk confirmed today on X that Tesla is already testing v14.3 internally right now. It will hit a wide release “in a few weeks,” so we should probably expect it by late April.
It’s in testing right now. Wide release in a few weeks.
— Elon Musk (@elonmusk) March 19, 2026
Overall, there are high hopes that v14.3 could be a true game changer for Tesla Full Self-Driving, as many believe it could be the version that Robotaxis in Austin, Texas, some of which are driverless and unsupervised, are running.
It could also include some major additions, including “Banish,” also referred to as “Reverse Summon,” which would go find a parking spot after dropping occupants off at their destination.
What Tesla will roll out, and when exactly it arrives, all remain to be seen, but fans have been ready for a new version as v14.2.2.5 has definitely run its course. We have had a lot of readers tell us their biggest request is to fix Navigation errors, which seem to be one of the most universal complaints among daily FSD users.
