Tesla has announced that it has produced its 100 millionth 4680 battery cell across all its factories. The update came just over three months after the company announced that it had produced a total of 50 million 4680 cells.
The milestone was posted on Tesla’s official social media account on X. Tesla included an image of its 100 millionth 4680 battery being held by an Optimus Gen 2 humanoid robot in its post.

Industry watchers who have closely watched the development of Tesla’s 4680 program were quite impressed with the electric vehicle maker’s recent milestone. Tesla, after all, just announced on June 5 that it had produced its 50 millionth 4680 cell at Giga Texas.
Considering the 101 days that have elapsed since the June announcement, Tesla appears to have produced, at least on average, about 495,000 4680 cells per day. Each Cybertruck is equipped with 1,344 4680 cells, so such an average output would translate to a production capacity of about 368 Cybertrucks a day, or 2,578 per week.

This also suggests that based on the output of the 4680 battery cells, Tesla could produce 33,514 Cybertrucks per quarter, or about 134,280 units of the all-electric pickup truck per year, as estimated by Tesla battery enthusiast The Limiting Factor in a post on X.
Recent aerial footage taken of the Giga Texas complex reveals that the electric vehicle maker is hard at work ramping up the production of the Cybertruck. Despite this, recent estimates hint that Tesla is still just closing in on producing 2,000 Cybertrucks per week.
Tesla just reached 100 million 4680 cells produced! ?
The last update was on the 5th of June where they announced 50 million cells produced.
There were 101 days in that time span, which means that on average, they produced 495,000 cells/day.
In terms of Cybertrucks, that’s… https://t.co/uKppZjLrIN— The Limiting Factor (@LimitingThe) September 14, 2024
This may then suggest that for now, at least, the supply of 4680 cells is no longer the bottleneck for the Cybertruck’s production. Of course, Tesla may also be stockpiling some 4680 cells in preparation for the Cybertruck’s increase in production once the Foundation Series formally ends.
The progress of Tesla’s 4680 battery cell program has been remarkable this year. Announced in Tesla’s 2020 Battery Day event, the 4680 cell program saw notable delays, to the point where company critics were claiming that Elon Musk might give up on the whole program. Earlier this year, however, a report from China emerged stating that Tesla is finally planning on mass producing the “complete” version of the 4680 cell—which includes a dry positive and negative electrode—by the end of this year.

Tesla expands massive safety feature worldwide in latest update
Tesla has expanded the footprint of a massive safety feature worldwide with a recent Software Update labeled as 2026.20.6. The expansion of the “Blind Spot Warning While Parked” feature represents the more widespread availability of the feature, which aims to prevent “dooring.”
Dooring is when a driver or passenger opens a car door into the path of an oncoming road user, usually a cyclist or motorcyclist. It is among the most common types of cycling accidents, the League of American Bicyclists says.
For this reason, Tesla created a feature that warns occupants not to open the door because an object is approaching. The feature will sound a chime, and it will also delay the opening of the door to prevent an incident.
The release notes state (via Not a Tesla App):
“If you attempt to open a door while an approaching object is detected in your blind spot (for example, a bicyclist approaching from behind) a chime sounds, and your door will not open upon initial button press. Wait a short time and press the button a second time to override the warning.”
Tesla initially rolled out this feature back in 2024 with the Model 3 “Highland.” However, it remained with the Model 3 exclusively for over a year; that was until Tesla added it to the Cybertruck this past Spring.
Now, it is making its way to the new Model Y, 2021 and newer Model S, and 2021 or newer Model X.
The prevention of dooring incidents could eliminate many injuries to cyclists, especially in an urban setting. Dooring accounts for 10-20 percent of bike-related crashes in major cities, and over 17,000 dooring-related incidents were treated in the U.S. over the course of a decade. These usually involve fractures, contusions, and head trauma.

Tesla sends production Cybercab with no steering wheel, pedals to on-road testing
Tesla confirmed this morning that it has sent the first production units, manufactured with no steering wheel or pedals, to on-road testing in Austin, sharing video of the first rides with no human controls.
The lack of steering wheels and pedals in the Cybercab aligns with Tesla’s self-certification of Robotaxi as Level 4 SAE, a platform it plans to make widespread through internal vehicles and customer-owned cars that will operate and generate revenue for individuals.
The start of these engineering tests is a major signal for Tesla, which plans to bring driverless, wheel-less, and pedal-less Cybercabs to market in the coming months. With production already well underway at Gigafactory Texas, where the Cybercab is built, there is some inclination to believe the first public rides could happen sooner rather than later.

Tesla’s engineering tests will put the Cybercab in real-world scenarios, testing not only the hardware, but more importantly, the software that drives the car around Austin with nobody supervising it within the car.
This is perhaps the biggest part of the internal testing process, especially prior to allowing regular, everyday people to hail the Cybercab for an autonomous ride. These early rides serve as a true benchmark for Tesla: How many rides can it achieve safely? How many miles did it travel consecutively without needing an intervention? What scenarios challenge the Full Self-Driving suite the most?
The proper precautions have already been put into place as well, as Tesla released the First Responders Guide to Cybercab over the weekend, ensuring that emergency services have 24/7 access to Robotaxi Assistance, as well as other boundaries, such as Geofencing features that can be used to redirect autonomous vehicle traffic due to accidents, road closures, construction, or maintenance.
Cybercab seems genuinely close to being added to the Robotaxi fleet in Austin, but Tesla has prioritized safety throughout this entire process. Therefore, we think it could be months before it truly starts giving rides to the public. People have been frustrated with this, but Robotaxi in Austin has a tremendous safety record so far, so the slow rollout has kept people safe and accidents to a minimum.
The most important thing is that Tesla continues to show consistent progress in the Cybercab’s ramp-up toward fleet addition. A few weeks back, we saw the EPA reward the Cybercab a Certificate of Conformity, allowing it to enter the stream of commerce. Then, we saw Tesla add decals, signaling that it was likely about to start testing it publicly. That has now happened.
The next big move will be the announcement of the first rides, so this Summer should be filled with anticipation.

Tesla Phone? Not quite, but close: analyst
For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.
It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.
Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.
The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.
Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.
The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.
SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.
There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.
The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.
