Texas-made Tesla Model Y with 4680 battery charges 0-97% in under 1 hour
A Texas-made Tesla Model Y with 4680 battery cells has been able to complete a charging session from 0% to 97% in 52 minutes.
Tesla advocate Ryan Levenson of The Kilowatts, who maintains several electric vehicles that he rents out on Turo, recently took delivery of a Texas-made Dual Motor Model Y. The vehicle is equipped with the company’s highly-anticipated 4680 battery cells, similar to a Texas-based Model Y purchased by teardown firm Munro & Associates.
As noted by the Tesla owner on Twitter, he actually drove the Texas-made Model Y until its battery showed 0 miles of range. Posts on social media indicated that the vehicle drove 3 miles beyond its “0 mile” point with seemingly no impact on acceleration.
Plugging into a Supercharger V3 station, Levenson was expecting to wait a bit in the vehicle until it filled its battery. The Model Y was plugged in at 12:25 a.m. with 0 miles of range remaining, and by 1:17 a.m., the Texas-made crossover was unplugged with 270 miles of range. It should be noted that the Dual Motor Model Y from Texas is listed with a range of 279 miles per charge on a full battery.
Charging from 0% to 97% in 52 minutes is very impressive, especially considering that the vehicle started its charging session at a time when it was technically “empty.” In later posts, Levenson noted that the Texas-made Model Y’s charging curve is quite interesting, as its charging rate immediately jumped to 250 kW when it was plugged in. This is quite different from previous Teslas, which tend to see a more deliberate increase to 250 kW.
Considering the fact that the Texas-made Model Y did not seem to encounter any limiters despite reaching 0 miles, and considering its ability to recharge practically its entire battery pack in less than an hour, it appears that Tesla’s 4680-equipped electric cars have some capabilities and advantages that are not openly discussed by the company.
When Tesla unveiled its 4680 battery technology at its Battery Day event in 2020, the company made it a point to highlight that its next-generation cells could pave the way for vast production efficiencies, weight savings, and more power. Since then, however, Tesla has been pretty tight-lipped about the actual advantages offered by 4680 cells, especially compared to the 2170 cells used in the Model Y produced in the Fremont Factory and Gigafactory Berlin.
For Levenson, the recent feat of his Texas-made Model Y suggests that 4680-equipped vehicles have a lot more to offer than what Tesla would suggest for now. In a statement to Teslarati, the EV advocate noted that there is definitely still quite a bit to discover with Tesla’s vehicles.
“Collecting this data opens more questions for me rather than answering them. Like why was my regenerative braking not limited even when the pack was full and why wasn’t my acceleration limited when I was near empty? For me, it’s indicating that there’s something big we don’t yet know or understand about the 4680 pack. Sure, it’s wishful thinking, but it absolutely could mean there’s more capacity to these new Austin-built Dual Motor Model Ys than Tesla is advertising or letting us access at this time,” he said.

Tesla launches Cybertruck vehicle-to-grid program in Texas
The initiative was announced by the official Tesla Energy account on social media platform X.
Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills.
The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.
Texas’ Cybertruck V2G program
In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.
During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.
The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.
Powershare Grid Support
To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.
Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.

Samsung nears Tesla AI chip ramp with early approval at TX factory
This marks a key step towards the tech giant’s production of Tesla’s next-generation AI5 chips in the United States.
Samsung has received temporary approval to begin limited operations at its semiconductor plant in Taylor, Texas.
This marks a key step towards the tech giant’s production of Tesla’s next-generation AI5 chips in the United States.
Samsung clears early operations hurdle
As noted in a report from Korea JoongAng Daily, Samsung Electronics has secured temporary certificates of occupancy (TCOs) for a portion of its semiconductor facility in Taylor. This should allow the facility to start operations ahead of full completion later this year.
City officials confirmed that approximately 88,000 square feet of Samsung’s Fab 1 building has received temporary approval, with additional areas expected to follow. The overall timeline for permitting the remaining sections has not yet been finalized.
Samsung’s Taylor facility is expected to manufacture Tesla’s AI5 chips once mass production begins in the second half of the year. The facility is also expected to produce Tesla’s upcoming AI6 chips.
Tesla CEO Elon Musk recently stated that the design for AI5 is nearly complete, and the development of AI6 is already underway. Musk has previously outlined an aggressive roadmap targeting nine-month design cycles for successive generations of its AI chips.
Samsung’s U.S. expansion
Construction at the Taylor site remains on schedule. Reports indicate Samsung plans to begin testing extreme ultraviolet (EUV) lithography equipment next month, a critical step for producing advanced 2-nanometer semiconductors.
Samsung is expected to complete 6 million square feet of floor space at the site by the end of this year, with an additional 1 million square feet planned by 2028. The full campus spans more than 1,200 acres.
Beyond Tesla, Samsung Foundry is also pursuing additional U.S. customers as demand for AI and high-performance computing chips accelerates. Company executives have stated that Samsung is looking to achieve more than 130% growth in 2-nanometer chip orders this year.
One of Samsung’s biggest rivals, TSMC, is also looking to expand its footprint in the United States, with reports suggesting that the company is considering expanding its Arizona facility to as many as 11 total plants. TSMC is also expected to produce Tesla’s AI5 chips.

Anti-Tesla union leader ditches X, urges use of Threads instead
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Marie Nilsson, chair of Sweden’s IF Metall union and a prominent critic of Tesla, has left X and is urging audiences to follow the union on Meta’s Threads instead.
Tesla Sweden and IF Metall have been engaged in a bitter dispute for over two years now.
Anti-Tesla union leader exits X
In a comment to Dagens Arbete (DA), Nilsson noted that her exit from X is not formally tied to IF Metall’s long-running labor dispute with Tesla Sweden. Still, she stated that her departure is affected by changes to the platform under Elon Musk’s leadership.
“We have stayed because many journalists pick up news there. But as more and more people have left X, we have felt that the standard has now been reached on that platform,” she said.
Jesper Pettersson, press officer at IF Metall, highlighted that the union’s departure from X is only indirectly linked to Tesla Sweden and Elon Musk. “Indirectly it does, since there is a lot of evidence that his ownership has caused the change in the platform to be so significant.
“We have nevertheless assessed that the platform had value for reaching journalists, politicians and other opinion leaders. But it is a microscopic proportion of the public and our members who are there, and now that value has decreased,” Petterson added.
IF Metall sees Threads as an X alternative
After leaving X, IF Metall has begun using Threads, Meta’s alternative to the social media platform. The union described the move as experimental, noting that it is still evaluating how effective the platform will be for outreach and visibility.
Pettersson acknowledged that Meta also does not operate under Sweden’s collective bargaining model, but said the union sees little alternative if it wants to remain visible online.
“In a perfect world, all large international companies would be supporters of the Swedish model when they come here. But unfortunately, the reality is not like that. If we are to be visible at all in this social media world, we have to play by the rules of the game. The alternative would be to become completely invisible, and that would not benefit our members,” he said.
