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.

Not a Tesla App
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 is rolling out a fairly big update for its iOS and early-access-only Robotaxi app, delivering a suite of improvements that address user feedback from the initial launch last month. The update improves the user experience with increased flexibility, more information, and overall design polish.
The most prominent feature in this update is that Tesla now allows you to adjust your pickup location. Once a Robotaxi arrives at your pickup location, you have 15 minutes to start the ride. The app will now display the remaining time your Robotaxi will wait for you, counting down from 15:00. The wait time is also shown in the iOS Live Activity if your phone is on the lock screen.
How Adjustable Pickups Work
We previously speculated that Tesla had predetermined pickup locations, as the pickup location wasn’t always where the user was. Now, with the ability to adjust the pickup location, we can clearly see that Tesla has specific locations where users can be picked up.
Rather than allowing users to drop a pin anywhere on the map, the new feature works by having the user drag the map to their desired area. The app then presents a list of nearby, predetermined locations to choose from. Once a user selects a spot from this curated list, they hit “Confirm.” The pickup site can also be changed while the vehicle is en route.
This specific implementation raises an interesting question: Why limit users to predetermined spots? The answer likely lies in how Tesla utilizes fleet data to improve its service.
Here is the new Tesla Robotaxi pickup location adjustment feature.
While the app is still only available on iOS through Apple’s TestFlight program, invited users can download and update the app.
Tesla included these release notes in update 25.7.0 of the Robotaxi app:

Why Predetermined Pick Up Spots?
The use of predetermined pickup points is less of a limitation and more of a feature. These curated locations are almost certainly spots that Tesla’s fleet data has identified as optimal and safe for an autonomous vehicle to perform a pickup or drop-off.
This suggests that Tesla is methodically “mapping” its service area not just for calibration and validation of FSD builds but also to help perform the first and last 50-foot interactions that are critical to a safe and smooth ride-hailing experience.
An optimal pickup point likely has several key characteristics identified by the fleet, including:
A safe and clear pull-away area away from traffic
Good visibility for cameras, free of obstructions
Easy entry and exit paths for an autonomous vehicle
This change to pick-up locations reveals how Tesla’s Robotaxi Network is more than just Unsupervised FSD. There are a lot of moving parts, many of which Tesla recently implemented, and others that likely still need to be implemented, such as automated charging.
Frequent Updates
This latest update delivers a much-needed feature for adjusting pickup locations, but it also gives us a view into exactly what Tesla is doing with all the data it is collecting with its validation vehicles rolling around Austin, alongside its Robotaxi fleet.
Tesla is quickly iterating on its app and presumably the vehicle’s software to build a reliable and predictable network, using data to perfect every aspect of the experience, from the moment you hail the ride to the moment you step out of the car.
The massive legislative effort titled the "Big Beautiful Bill" is taking direct aim at what has become one of Tesla’s most critical and profitable revenue streams: the sale of US regulatory credits. The bill could eliminate billions of dollars from Tesla’s bottom line each year and will slow down the transition to electric vehicles in the US.
The financial stakes for Tesla are absolutely immense. In 2024, Tesla generated $2.76 billion from selling these credits. This high-margin revenue was the sole reason Tesla posted a profit in Q1 2025; without the $595 million from regulatory credits, Tesla’s reported $409 million in profit would have been a $189 million loss.
How the ZEV Credit System Works
Zero-Emission Vehicle (ZEV) credits are part of state-level programs, led by California, designed to accelerate the adoption of electric vehicles. Each year, automakers are required to hold a certain number of ZEV credits, with the amount based on their total vehicle sales within that state. Under this system, automakers that fail to sell a certain percentage of zero-emission vehicles must either pay a significant fine or purchase credits from a company that exceeds the mandate.
Automakers who fail to sell enough EVs to meet their quota have a deficit and face two choices: pay a hefty fine to the state government for each missing credit (for example, $5,000 per credit in California) or buy credits from a company with a surplus.
As an all-EV company, Tesla generates a massive surplus of these credits. It can then turn around and sell them to legacy automakers at prices cheaper than the fine, creating a win-win scenario: the legacy automaker avoids a larger penalty, and Tesla gains a lucrative, near-pure-profit revenue stream.
This new bill will dismantle this by eliminating the financial penalties for non-compliance, which would effectively make Tesla’s credits worthless. While the ZEV program is a state law, the Big Beautiful Bill will fully eliminate the penalties at a federal level.
A Multi-Billion Dollar Impact
The removal of US ZEGV credits would be a severe blow to Tesla’s financials. One JPMorgan analyst estimated that the move could reduce Tesla’s earnings by over 50%, representing a potential annual loss of $2 billion. While Tesla also earns similar credits in Europe and China, analysts suggest that 80-90% of its credit revenue in Q1 2025 came from US programs.
Why the Program Exists
While the impact on Tesla would be direct and immediate, the credit system has a wider purpose. It creates a strong financial incentive for legacy automakers to develop and accelerate their zero-emission vehicle programs, whether it’s hydrogen, electric, or another alternative.
Eliminating the need for these credits would remove that financial pressure. This could allow traditional automakers to slow their EV transition in the US without the fear of a financial penalty, potentially leading to fewer EV choices for consumers and a slower path to vehicle electrification in the country.
Big, But Not Beautiful
On Sunday Morning TV, Elon Musk was asked his thoughts on the Big Beautiful Bill. They were pretty simple. A bill could be big, or it could be beautiful - I don’t know if it can be both, Musk stated.

The bill poses a threat to Tesla’s bottom line and to the adoption of EVs in the US market, where automakers will no longer have a financial incentive to transition to cleaner vehicles, a market they’ve regularly struggled in when competing against Tesla.
Tesla will have to work carefully in the future to cut expenses to remain profitable after the elimination of these regulatory credits.
