EXCLUSIVE: Tesla Cybertruck battery packs to be built at Fremont Factory
Tesla plans to start building battery packs for the upcoming Cybertruck on a new cell manufacturing line in the Fremont factory, people with knowledge of the project told Teslarati.
In August, we reported that Tesla had filed to build a new battery manufacturing equipment line on the second floor of the Fremont factory. This filing, which was submitted to the City of Fremont on August 30, relates to the module portion of the line, Tesla said.
Tesla described the project as “CTA Battery B-Build,” the filing shows.

Tesla is ultimately planning to build the Cybertruck in Austin at Gigafactory Texas. However, battery cells and cell pack manufacturing are not yet ready to take off at the new Tesla plant, which is located just outside Austin. Tesla applied to build a battery and cathode manufacturing building at Gigafactory Texas earlier this year, and while the project has been started, it likely will not be ready for the Cybertruck’s projected launch in mid-2023.
With an extensive order log that features over 1 million total reservations, Tesla is preparing for Cybertruck manufacturing by building the battery packs at a plant that is already operational. The Fremont facility, the only Tesla plant manufacturing all four vehicles the company builds, was ultimately chosen for the task of kicking off Cybertruck pack manufacturing, Teslarati confirmed with sources familiar with the matter.
Cybertruck Battery Pack Manufacturing will start in Fremont
Sources familiar with the matter told Teslarati the second-floor manufacturing line that Tesla filed to build in August will manufacture the Cybertruck packs. Tesla will take the 4680 battery cells produced at the Kato Road facility or another previously utilized cell design manufactured at Gigafactory Nevada and put them into modules and packs that are manufactured on the new Fremont battery line.
Currently, the line is being completed by construction crews on site, who are making daily progress. Additionally, Tesla engineers are installing automation equipment to produce the Cybertruck battery packs.
Tesla did not immediately respond to our request for comment.
Kicking Cybertruck Module Production into “Plaid Mode”
Tesla is also working hard to kick off Cybertruck pack production as time is extremely limited. Tesla has a series of vehicles, referred to as “carriers,” which transport batteries throughout the factory. The company recently ordered around 300 new carriers for the factory as cell and battery pack manufacturing is set to ramp drastically.
The sources also said the Cybertruck battery pack line is currently being tested with Tesla’s automation equipment. Tesla is working to ramp the line quickly as Cybertruck vehicle manufacturing is planned for next year at Gigafactory Texas.
2023: The Year of the Tesla Cybertruck?
Tesla is set to build the Cybertruck at Gigafactory Texas. After unveiling the all-electric pickup in 2019, Tesla has delayed initial production on several occasions due to supply chain issues and other challenges.
“In 2022, supply chain will continue to be the fundamental limiter of output across all factories,” Musk said during Tesla’s Q4 and 2021 Full Year Earnings Call in January. So the chip shortage, while better than last year, is still an issue. And, yeah, so that’s — there are multiple supply chain challenges.”
Musk went on to say that the challenges would delay the launch of any new products in 2022. “We will, however, do a lot of engineering and tooling, what not to create those vehicles: Cybertruck, Semi, Roadster, Optimus, and be ready to bring those to production hopefully next year. That is most likely.”
Although Tesla is planning to begin deliveries of the Semi on December 1, all other projects have been effectively delayed until next year, but preparation to launch those projects is evidently a priority within the factories.
4680 cells are not constrained but are they going into the Cybertruck?
Tesla’s Vice President of Powertrain Drew Baglino detailed earlier this year that the company was not constrained in terms of 4680 battery cell availability.
“So throughout 2021, we focused on growing cell supply alongside our in-house 4680 effort to provide us flexibility and insurance as we attempt to grow as fast as possible,” Baglino said on the Q4 and Full Year 2021 Earnings Call in January. “4680 cells are not a constraint to our 2022 volume plans based on the information we have.”
What Baglino said next on the call likely indicates what Tesla was preparing the Cybertruck for: pack manufacturing at Fremont, shipping the packs to Texas, and then installing them into vehicles:
“But we are making meaningful progress of the ramp curve in Kato. We’re building 4680 structural packs every day, which are being assembled into vehicles in Texas. I was driving one yesterday and the day before. And we believe our first 4680 vehicles will be delivered this quarter.”
The Kato Road facility has supported Tesla’s 4680 cell needs thus far. The 4680 packs were installed on some Gigafactory Texas-built Model Ys, and were reviewed by Munro Live earlier this year. Fremont will likely support Cybertruck pack manufacturing for some time, utilizing cells from Kato Road and from suppliers like Panasonic when they ultimately being manufacturing the battery for Tesla.
As Cybertruck manufacturing ramps up into late 2023, 2024, and beyond, packs will then be at Fremont and Gigafactory Texas, which would likely entirely support Cybertruck production.

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.

Tesla expands Unsupervised Robotaxi service to two new cities
This expansion builds directly on Tesla’s existing operations. Robotaxi has been ramping unsupervised rides in Austin for months and maintains activity in the San Francisco Bay Area.
Tesla has taken a major step forward in its autonomous ride-hailing ambitions.
On April 18, the company’s official Robotaxi account announced that Robotaxi service is now rolling out in Dallas and Houston, Texas. The update signals the rapid scaling of unsupervised autonomous operations in the Lone Star State.
The announcement includes a compelling 14-second video captured from inside a Model Y. Shot from the passenger perspective, the footage shows the vehicle navigating suburban roads in both cities with zero driver intervention, with no Safety Monitor to be seen.

This expansion builds directly on Tesla’s existing operations. Robotaxi has been ramping unsupervised rides in Austin for months and maintains activity in the San Francisco Bay Area.
With Dallas and Houston now live, Texas hosts three active hubs—an impressive concentration that triples the company’s Lone Star footprint in just weeks. The move aligns with Tesla’s Q4 2025 earnings guidance, which outlined a broader H1 2026 rollout across seven U.S. cities, including Phoenix, Miami, Orlando, Tampa, and Las Vegas.
Texas offers favorable regulations, high ride-share demand, and relatively straightforward suburban-to-urban driving patterns ideal for early autonomous scaling. While initial geofences appear modest—roughly 25 square miles per city—Tesla has historically expanded these zones quickly as it gathers real-world data.
Tesla confirms Robotaxi expansion plans with new cities and aggressive timeline
Unsupervised operation marks a critical milestone: passengers can summon, ride, and exit without safety drivers, a leap beyond many competitors still requiring human oversight.
For Tesla, the implications are significant. Successful scaling in major metros could accelerate the transition to a fully driverless fleet, unlocking new revenue streams and validating years of Full Self-Driving investment.
Riders gain convenient, potentially lower-cost mobility, while the company edges closer to Elon Musk’s vision of Robotaxis transforming urban transport.
As Tesla pushes into more cities this year, today’s launch in Dallas and Houston underscores its momentum. Hopefully, Tesla will be able to expand unsupervised rides to another U.S. state soon, which will mark yet another chapter in this short-but-encouraging Robotaxi story.

Tesla is pushing Robotaxi features to owner cars with Spring Update
Tesla has quietly begun rolling out one of its most forward-looking Robotaxi-inspired features to existing customer vehicles.
Tesla is starting to push Robotaxi features to owner cars, and the first instances are coming as the Spring 2026 Update starts to roll out.
Tesla has quietly begun rolling out one of its most forward-looking Robotaxi-inspired features to existing customer vehicles.
With the 2026 Spring Update (version 2026.14+), the rear passenger display now features a fully interactive navigation map that works while the car is driving — a capability previously reserved for Tesla Robotaxi.
First look at Tesla’s v2026.14.1 Spring Update.
🧭Rear screen interactive map #teslaupdate #tesla #teslasrpingupdate pic.twitter.com/yH3T4U8qHp— Sergiu Mogan (@sergiumogan) April 17, 2026
Until now, Tesla’s rear displays have been largely limited to media controls, climate settings, and static route overviews. The new interactive map transforms the backseat into an active navigation hub, exactly the kind of passenger-first interface Tesla has been prototyping for its driverless fleet.
In a Robotaxi, where no one sits behind the wheel, every rider will need intuitive, real-time map access. By shipping this UI into thousands of owner cars months ahead of the Cybercab’s planned unveiling, Tesla is stress-testing the software in real-world conditions and giving loyal customers an early taste of the autonomous future.
The rollout is still in its early wave. Only a small number of vehicles have received 2026.14.1 so far, but the feature is expected to expand rapidly in the coming weeks. Owners of Model S, Model X, Model 3, Model Y, and Cybertruck are all eligible.
For buyers of the new Signature Edition Model S and X Plaid vehicles — whose deliveries begin in May — the update will likely arrive shortly after they take delivery, meaning the final chapter of Tesla’s flagship lineup will ship with cutting-edge Robotaxi preview tech baked in.
Elon Musk has long emphasized that Tesla ships supporting infrastructure well before new products launch. This rear-map rollout is a textbook example of that philosophy — quietly preparing both the software and the customer base for a world of fully driverless rides.
While the interactive map may seem like a modest convenience upgrade on the surface, its deeper purpose is unmistakable. Tesla is using its massive installed base of vehicles as a proving ground for the exact passenger experience that will define the Robotaxi era.
For current owners, it’s a free preview of tomorrow’s mobility; for the company, it’s invaluable data and real-world validation before the Cybercab hits the streets.
