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 has introduced an enhanced visualization in its Supercharger navigation system, building directly on the Site Maps feature rolled out a few months ago.
This latest software update adds detailed 3D icons that represent specific vehicle models parked at charging stalls, offering drivers a more precise view of site occupancy and layout.
The Site Maps debuted in Tesla’s 2025 Holiday Update, providing 3D overviews of select Supercharger locations with real-time stall availability.
Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
Drivers could see which spots were open, occupied, or out of service when navigating to supported stations.
Now, the system takes this capability further by rendering accurate representations of Tesla vehicles, including distinctions between models such as the Model 3, Model Y, Model S, Model X, and Cybertruck. These icons appear as lifelike 3D renderings, complete with recognizable shapes and proportions that match the actual cars charging at the site:

This refinement improves the user experience during road trips and daily charging stops. As drivers approach a Supercharger, the navigation display now shows not just generic occupied markers but identifiable vehicle types plugged into each stall.
Blue indicators highlight active charging sessions, while other visual cues denote availability or maintenance status. The feature integrates seamlessly with the existing map interface, allowing quick assessment of the best available spot based on vehicle size and positioning.
Tesla continues to expand the availability of these detailed Site Maps across its global network. Initially piloted at a limited number of locations, the rollout has progressed steadily, with more stations gaining support in recent software versions.
Owners benefit from better planning, as the system helps identify compatible stalls and reduces uncertainty upon arrival. The update reflects Tesla’s ongoing commitment to refining its navigation and charging ecosystem through iterative software improvements.
In addition to model-specific icons, the enhanced maps maintain all prior functionalities, such as integration with nearby amenities and energy usage predictions. This ensures a comprehensive tool for efficient Supercharging.
As Tesla’s fleet grows and the network scales, such features play a key role in optimizing the overall ownership experience. Future updates may extend similar visualizations to additional sites and incorporate even more data points for drivers.
With this piggyback enhancement, Tesla demonstrates how small but thoughtful additions can elevate an already useful tool, making Supercharger visits smoother and more informed for its customers. The company is expected to broaden the feature’s reach in upcoming releases, further solidifying its leadership in EV charging infrastructure.
Tesla Full Self-Driving v14.3.3 driver monitoring was reportedly scaled back in recent releases, but a new version that was released in the early hours of June 3 aimed to do a better job of keeping those in control of their cars honest, according to release notes.
The release notes for FSD v14.3.3, via Software Version 2026.14.6.7 added:
“Improved driver monitoring system sensitivity with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions.”
However, Tesla said this was already enabled in the first rollout of FSD v14.3.3 in late May. We tested it anyway, especially as the Standard Speed Profile seemed less-than-worried about what you were doing during operation.
I decided to try out the Hurry and Mad Max Speed Profiles for this test, and it gave me results that I would have expected. Tesla has evidently ramped up driver monitoring based on the Speed Profile you are using to travel.
The more aggressive the Speed Profile, the more on the hook you will be for taking your attention away from the road. Our testing showed that Mad Max was less likely to allow you to do normal things like change music or adjust navigation without getting an on-screen warning or nag from the driver monitoring system.
Hurry Mode Results
On Hurry, the driver monitoring system on FSD v14.3.3, via Software Version 2026.14.6.7, was more restrictive than Standard but less restrictive than Mad Max. I found that I could scroll through music options for a considerable amount of time, more than 30 seconds:
Roughly :31 between first touching the center screen and getting the first nag

Standard gave me about 80 seconds of phone scrolling with absolutely no nags or warnings in a previous test. It is worth noting that this was a previous branch of v14.3.3, but Standard is such a goodie-two-shoes on the road that it is my impression it would not change much.
Here’s an 80-second phone nag test on Tesla FSD v14.3.3.

Mad Max Results
I spent the majority of the drive on Mad Max to see how it truly reacted to the driver having their attention elsewhere. While I did do a short phone test, I am aiming to steer away from those and use the center screen. I think it is a valid criticism that the phone test is dangerous and, not to mention, illegal in Pennsylvania. Changing the navigation and music is a more reasonable, more responsible, and safer test.
With Mad Max being the fastest and most aggressive Speed Profile, I anticipated this being the quickest mode to give me an alert that I needed to look at the road. That was the case with music:

As well as adjusting Navigation, when I received two nags:

— TESLARATI (@Teslarati) June 3, 2026
These nags were more than reasonable, and I think it’s probably good that Tesla is ramping up the driver monitoring. I do believe that it should be relatively strict across all of the Speed Profiles, especially with phone use. When using the center screen, the nag intervals should be based on the speed profile you are utilizing at the time.
These driver monitoring adjustments are a great thing to have while FSD is still under its “Supervised” moniker, but I expect Tesla to continue pushing the limits on what it will allow, especially considering CEO Elon Musk has hinted that phone use is capable with the more recent versions.

Tesla has responded to the skeptics of its Robotaxi program by launching a massive expansion of the unsupervised program in its initial rollout city of Austin.
The company’s geofence, the enabled area of operation for rides, now covers the entire Austin Metropolitan area, an incredible move just days after media headlines attempted to discredit the ride-hailing service.
Those who have access to the Tesla Robotaxi app on their smartphones can now request a ride in any portion of the Austin Metro area. The company confirmed this on the social media platform X:
Unsupervised Robotaxi now in the entire Austin Metro area https://t.co/eXNBdarvVS
— Tesla Robotaxi (@robotaxi) June 3, 2026
This is Tesla’s fifth expansion of the geofence, with the others occurring in July, early August, late August, and late October 2025. It has remained at that size since October 26, but Tesla has now more than doubled that size.
It is now covering the entire area, including suburbs like Pflugerville and Manor, as well as I-35 highways, Gigafactory Texas, and the Austin-Bergstrom Airport.
The move comes just days after various media outlets highlighted the small fleet size of Tesla’s Robotaxi fleet in Austin, something that is a reasonable criticism but an understandable move on the company’s part to prioritize safety.
Tesla has expanded its Robotaxi geofence many times, but its fleet has remained at a relatively conservative size as the company continues to push safety as its most crucial metric.
The latest expansion is a key indicator of Tesla’s comfort level to expand the ride-hailing service. The move shows Tesla is scaling unsupervised autonomy, as it demonstrates that the company’s Full Self-Driving system has reached sufficient reliability for a broader real-world deployment, which is something the company has worked on extensively.
It also shows Tesla is game for a competition with its rivals in the autonomous ride-hailing sector. Tesla has often matched or exceeded competitors like Waymo in coverage area, despite its smaller fleet. This step highlights Tesla’s iterative, data-driven progress toward a high-margin, app-based Robotaxi network.
It’s not the absolute largest area expansion ever, but achieving full unsupervised operations across a major metro is a key moment in the Robotaxi story. It shifts the program from limited pilot/testing toward a more mature commercial service, while gathering the miles needed for faster growth.
