During the 2024 Shareholder Meeting, Elon Musk announced that Tesla has made new innovations on the 4680 cell standard. Tesla has been working hard for several years to get a functional 4680 cell in production that either matches or beats the performance of the existing 2170 cell. The official Cybertruck account also shared an image (below) of the first 4680 dry-cathode process Cybertruck with its production crew on X.
We’re going to take a bit of a dive into the 4680, what exactly this new process and cell is, and then some of its possible advantages. So, grab your charging cable!

Dry Battery Electrode (DBE) is a different process overall from the current Wet Battery Electrode (WBE) that is common today. This dry process removes the highly toxic solvents and furnace baking processes from the equation, saving both time and space, while also being environmentally friendly.
The Dry Cathode we’re talking about specifically means that the electrode – the conducting terminal at the edges of the battery – is produced in a dry process. In the previous process, it was produced with a wet process.
Tesla’s 4680 cell suppliers – LG and Panasonic – have both been working hard to cut down on costs and ramp up their own 4680 cell production while Tesla works on their own internal improvements as well. If Tesla has found a means to easily scale the Dry Cathode method, it’ll make 4680 cells and the batteries that they are a part of - cheaper to produce.

Tesla has used the 4680 cells to make structural battery packs for the Model Y. However, these vehicles had poor charging performance and lower energy density, and they were quickly removed from sales. The sheer size of the 4680 cell made it difficult to cool, limiting its performance.
The updated 4680 cell was announced at the November 2023 Earnings Call as Cybercell, making a comeback for the Cybertruck. This new version was going to have better energy density, as well as improved charging performance.
Sandy Munro of Teardown Titan fame showed that this improved version has about a 12% energy density increase, a pretty significant improvement. You can watch his teardown of the Cybertruck below.
Tabless Design
The tabless design of the 4680 cell also has an impact on its production, and how easy it is to manufacture. Think of the tabs as the little nubs on the top of a regular small battery. The lack of tabs means that production of the cell body doesn’t have to pause to add the tabs, reducing the chance for defects with the elimination of a process, and making it faster to boot.
Removing the tab also helps in cutting down the distance that electrons have to travel to get in and out of the cell – this means less resistance, and less energy lost in the process, increasing overall vehicle efficiency.
Advantages
This new 4680 cell process has a few advantages – including an overall cost reduction of up to 50% compared to the current wet process. That’s in addition to the dry process being more environmentally friendly, which will also allow for manufacturing of the cell to scale quicker.
Tesla wants to move from the standard 2170 cell to the 4680 cell for several reasons. The biggest, by far, is cost savings. The 4680 cell is physically a bigger cell and can be used to structurally support the vehicle, meaning cost savings on both, the production of the 4680 cell and the structure of the vehicle.
Easy and Cheap
There’s more too – the 4680 cell will be easier to manufacture because of its bigger size. The 2170 cell is tall and thin, while the 4680 cell is wide and stout. In addition, its unique tab-less design is supposed to generate less resistance, improving charging speeds and cell performance.
Essentially, Tesla can fill the space taken up by 4,400 2170 cells with only 960 4680 cells. This results in a significant reduction in the material used to encase each individual cell, thereby saving space and maximizing energy density for the space the battery pack takes up.
All in all, that could mean a future price drop for the Cybertruck as well as increase the rate of production. Tesla has envisioned producing approximately 250,000 Cybertrucks per year, and they’ll need a lot of 4680 battery packs to do so.
In the future, we can see Tesla bringing the 4680 cell with all these improvements - and more - to the rest of its vehicle lineup, as they will eventually surpass the 2170 cell technology.

Tesla’s long-awaited ambitions for a fully autonomous Robotaxi network powered by the futuristic, control-less Cybercab have finally started to take shape.
During their Q1 2025 earnings call, Tesla shared new details about its Robotaxi network, including that the network will start with new Model Ys. The Cybercab will join the network in 2026.
Robotaxi Plans
Tesla confirmed during the Earnings Call that it is on track to conduct the pilot launch of its Robotaxi network in Austin in June 2025. The first vehicles deployed for this service won’t be Cybercabs, as production for those is still in the prototyping stage.
However, Tesla did outline part of their plan for the Robotaxi network rollout. The initial aim is to begin driverless operations in Austin and then expand the service to other cities within the United States by the end of 2025. Interestingly, Tesla is also testing in California - albeit with safety drivers at this time.
Not a Tesla App
Looking further ahead, there are ambitious plans to ramp up operations to have millions of vehicles operating autonomously within the network by the end of 2026. While substantial revenue generation won’t be immediate, Tesla anticipates that the Robotaxi network will start to “meaningfully move the financial needle” in the second half of 2026.
Tesla also highlighted the current real-world benefits that FSD is already offering today—and will be able to offer to many more people in the near future.
These include reducing effort and time spent on daily commuting or transit, as well as improving mobility for customers with disabilities. Tesla plans to emphasize some of these community stories and wants to highlight the advantages and capabilities of FSD to improve people’s lives.
Robotaxi App and Robotaxi Vehicle UI
Not a Tesla App
After the call, Tesla AI also shared a video showcasing the Robotaxi interface in the Tesla app, as well as some footage that included the in-vehicle UI, at least as it currently stands.
The video shows Tesla employees using and testing Robotaxi features, although there are safety drivers in place. It looks like there is already a set of well-integrated UI mechanisms for both the front and rear screen when in Robotaxi mode.
Tesla is testing this today, and this network has already completed 1,500 trips, totaling approximately 15,000 miles. The system is being tested for vehicle allocation, mission control, and remote assistance operations.
Remote Operators
Inevitably, edge cases or unique situations will come up, and they will be difficult to handle. For these cases, where a Robotaxi vehicle gets stuck or requires assistance, Tesla will likely implement remote support.
While they didn’t completely confirm remote support operators on the Earnings Call, Tesla has previously posted positions for Teleoperator Engineers for Robotaxi, and an AI T=team member posted on LinkedIn about testing for remote assistance operations.
Scaling Up
Tesla initially intends to deploy a relatively small fleet in Austin, with its pilot beginning with about 10 to 20 vehicles on day 1. They will scale up gradually as the systems are validated and operations are refined, and the target is for anyone visiting Austin to be able to hail a robotaxi by the end of June or early July 2025.
Scaling Out
Not a Tesla App
Tesla’s confidence in scaling out stems from its generalized approach with FSD. The team believes that once FSD is thoroughly verified and capable in a few diverse North American cities, deploying it to any other North American city should be technically feasible. After all, driving regulations don’t vary much from one major city to another, except for things like no right turns on red lights.
The primary limitation with scaling out geographically is expected to be securing regulatory approvals in different regions and jurisdictions. While the principles of Tesla’s FSD are expected to apply globally, as with the China rollout, regulation will continue to be a considerable hurdle.

Tesla’s fully autonomous, two-seater vehicle, the Cybercab, is also being developed. While volume production for the Cybercab won’t begin until 2026, Tesla is already undergoing sample production validation. The first actual Cybercab builds are expected to be completed near the end of Q2 2025, and we’re excited to see if anything changes from the prototypes shown at We, Robot.
Tesla intends to build Cybercab at Giga Texas, and the production line is on schedule, according to Tesla. Cybercab production will not require a new building and will be built inside the existing Giga Texas factory.
Unboxed Method
Tesla's Shareholder Deck for Q1 2025 is now out, and we're 40 minutes away from the Earnings Call.
It seems Tesla won't be using the unboxed process for its more affordable model - which is a new vehicle.
The Cybercab’s production and low-cost methodology heavily rely upon Tesla’s innovative new unboxed manufacturing method. Tesla’s executive team mentioned that progress and implementation with this new manufacturing solution was going well, and it will be key to lowering the cost of production while considerably raising the level of automation.
Tesla has already achieved key milestones with this method, including successfully integrating large sub-assemblies and resolving challenges related to connecting portions of the vehicle's ceiling during the process. They have also successfully completed corrosion testing related to the new assembly method, as well as begun initial crash testing for the Cybercab.
All of that and more will eventually be incorporated into other vehicle production lines, and the Cybertruck is already benefiting from some aspects of these developments. With a final ambition of achieving a 5-second cycle time per Cybercab, Tesla has come a long way—but it still has quite a bit to go. They’ve managed to meet a 33-second cycle time for the Model Y at Giga Shanghai between two production lines, but 5 seconds per vehicle is quite ambitious.
Not a Tesla App
With all that said, between Robotaxi and Cybercab, there is a lot of interesting news coming from Tesla. We expect this to continue throughout the year as Tesla launches its network and then aims to release FSD Unsupervised to customers, with a potential price increase.
