Tesla has moved forward with its expansion of the Kato Road facility, where the 4680 battery cell is developed.
Filings seen by Teslarati show the automaker has continued with its expansion of the Materials Lab, where research and development of the 4680 cell and other battery projects take place.
Tesla filed for revisions to the expansion project in late April, but the Materials Lab has been undergoing modifications since 2021.
Tesla filed its initial permit for the expansion of the Materials Lab at 47400 Kato Road in Fremont in July 2021. It has continued to fill out over the past year and a half, with the most recent filings coming in early and late April of this year.
With the 4680 project continuing to expand in terms of production, Tesla is ramping up manufacturing of the cell to accommodate its appearance in vehicles, including the Model Y that is built at Gigafactory Texas.
Tesla first unveiled the 4680 cell in 2020 at the company’s Battery Day event. The automaker detailed how a new cell design would not only increase battery longevity, but also power and vehicle range, which has not yet been applied to cars with a 4680 pack.
Tesla Model Y vehicles fitted with the 4680 cell have actually shown to have less range than other vehicles, but there are be several reasons for this, and Tesla has gone out of their way to explain it.
Tesla said in a rebuttal to criticism of the range ratings of the 4680 pack:
“Introducing the new cells meant introducing a new variant of the Model Y. We’ve designed Model Y AWD to have an attractive combination of range, performance and price that will be the best fit for many customers and will make Model Y accessible to more customers, furthering our mission. Those interested in an even more capable Model Y should explore Model Y Long Range and Performance. We’ve chosen to put a lower-energy battery pack in Model Y AWD, resulting in lower range, acceleration, and price point.”
We have continued to track developments at both Kato Road and the Fremont Factory as Tesla has hinted in the past it could expand the production facility to make way for higher manufacturing rates.
Tesla 4680 production hits milestone of 868k cells in seven days
Tesla has a lofty goal of producing 1.8 million cars this year, and with recently expanded efforts at both Giga Texas and Giga Berlin, the automaker seems on track to reach this. If it does expand the Fremont Factory as well, growth to the 4680 cell project only seems logical.

Tesla announces major milestone at Gigafactory Shanghai
First deliveries started in December 2019, with the first units being given to employees. By the end of 2020, the plant was building cars at a run rate of around 150,000 vehicles annually.
Tesla has announced a major milestone at its Chinese manufacturing facility, Gigafactory Shanghai, confirming on Monday that it had built its four millionth vehicle.
Tesla Gigafactory Shanghai first started building cars back in October 2019 with Model 3 assembly, just ten months after the company broke ground on the plant’s 86-hectare piece of land.
First deliveries started in December 2019, with the first units being given to employees. By the end of 2020, the plant was building cars at a run rate of around 150,000 vehicles annually. Production continued to ramp up, and by September 2023, less than three years after it started building Tesla’s EVs, it had built its two millionth vehicle.
Fast forward to December 2025, and Tesla has confirmed that four million cars have rolled off of production lines at the plant, a major milestone in the six short years it has been active:

The capacity at Giga Shanghai is exceeding 950,000 vehicles per year, and this year, the company has delivered 675,000 cars through the first three quarters. It is also the only plant to manufacture the Model Y L, a longer wheel-based configuration of the all-electric crossover that is exclusive to the Chinese market.
Gigafactory Shanghai’s four million cars have not all stayed within the domestic market, either. For a considerable period, the factory was exporting a significant portion of its monthly production to Europe, helping Gigafactory Berlin supplement some Model Y volume and all of its Model 3 deliveries. This is due to the Berlin plant’s exclusive production plans for the Model 3.
The site is one of the most crucial in the company’s global plans, and Gigafactory Shanghai’s incredible pace, which has led to four million production units in just about six years. It’s fair to say that it won’t be long until we’re seeing Tesla celebrate the plant’s five millionth vehicle produced, which should happen sometime late next year or in early 2027, based on its current manufacturing pace.
The company also builds the Megapack on the property in an adjacent Megafactory.

Tesla gamifies Supercharging with new ‘Charging Passport’
It will also include things like badges for special charging spots, among other metrics that will show all of the different places people have traveled to plug in for range.
Tesla is gamifying its Supercharging experience by offering a new “Charging Passport,” hoping to add a new layer to the ownership experience.
While it is not part of the Holiday Update, it is rolling out around the same time and offers a handful of cool new features.
Tesla’s Charging Passport will be available within the smartphone app and will give a yearly summary of your charging experience, helping encapsulate your travel for that year.

• Total unique Superchargers visited

Tesla will include the following metrics within the new Charging Passport option within the Tesla app:
- Charging badges: Iconic charging badges for visiting places like the Tesla Diner, Oasis Supercharger, etc., Explorer Badge, and more
- Total Unique Superchargers Visited
- Total Charging Sessions
- Total Miles Added during Charging Sessions
- Top Charging Day
- Longest Trip
- Favorite Charging Locations
This will give people a unique way to see their travels throughout the year, and although it is not necessarily something that is needed or adds any genuine value, it is something that many owners will like to look back on. After all, things like Spotify Wrapped and Apple Music Replay have been a great way for people to see what music they listened to throughout the year.
This is essentially Tesla’s version of that.
With a handful of unique Superchargers already active, Tesla is also building some new ones, like a UFO-inspired location in New Mexico, near Roswell.

Tesla launches its coolest gift idea ever just a few weeks after it was announced
“Gift one month of Full Self-Driving (Supervised), which allows the vehicle to drive itself almost anywhere with minimal intervention.”
Tesla has launched its coolest gift idea ever, just a few weeks after it was announced.
Tesla is now giving owners the opportunity to gift Full Self-Driving for one month to friends or family through a new gifting program that was suggested to the company last month.
The program will enable people to send a fellow Tesla owner one month of the company’s semi-autonomous driving software, helping them to experience the Full Self-Driving suite and potentially help Tesla gain them as a subscriber of the program, or even an outright purchase.
Tesla is going to allow owners to purchase an FSD Subscription for another owner for different month options
You’ll be able to gift FSD to someone! https://t.co/V29dhf5URj
— TESLARATI (@Teslarati) November 3, 2025
Tesla has officially launched the program on its Shop. Sending one month of Full Self-Driving costs $112:
“Gift one month of Full Self-Driving (Supervised), which allows the vehicle to drive itself almost anywhere with minimal intervention. All sales are final. Can only be purchased and redeemed in the U.S. This gift card is valued at $112.00 and is intended to cover the price of one month of FSD (Supervised), including up to 13% sales tax. It is not guaranteed to cover the full monthly price if pricing or tax rates change. This gift card can be stored in Tesla Wallet and redeemed toward FSD (Supervised) or any other Tesla product or service that accepts gift card payments.”
Tesla has done a great job of expanding Full Self-Driving access over the past few years, especially by offering things like the Subscription program, free trials through referrals, and now this gift card program.
Gifting Full Self-Driving is another iteration of Tesla’s “butts in seats” strategy, which is its belief that it can flip consumers to its vehicles and products by simply letting people experience them.
There is also a reason behind pushing Full Self-Driving so hard, and it has to do with CEO Elon Musk’s compensation package. One tranche requires Musk to achieve a certain number of active paid Full Self-Driving subscriptions.
More people who try the suite are likely to pay for it over the long term.
