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.

The long long wait for FSD (Supervised) in Australia and New Zealand may be coming to an end. Thom Drew, Tesla’s Country Director for Australia & New Zealand, has confirmed on LinkedIn that Tesla has been working with local authorities in both countries and that there are no regulatory blockers for the release of FSD in the region.
The confirmation came in response to questions following Tesla’s FSD demo video in Sydney, Australia.
Hurdles Cleared
For many years, the main question surrounding the release of FSD in other Asia-Pacific countries, especially Australia, has been the status of regulatory approval. Drew’s statement provides the clearest answer yet regarding regulatory barriers, and it appears that the path is clear from a governmental standpoint.
“We have been working with local authorities across AU & NZ and there are no regulatory blockers for release. We are running through the final stages of validation prior to public release. Looking to start with HW4 on certain vehicles and then release in phases from there.”

With the regulatory question answered, the timeline for the release is now entirely in Tesla’s hands. According to his statement, Tesla is in the final phases before a public rollout, likely meaning Tesla is doing some final testing and veritifcation on local roads before flipping the switch.

The Rollout Plan: HW4 First
Drew also provided the first details on how Tesla plans to launch FSD in the two countries, and it seems to be a similar approach to the one Tesla took in China.
That means that the release will begin with AI4 (HW4) equipped vehicles first. Once those vehicles are up and running, they will slowly begin to phase in older AI3 (HW3) vehicles over the next few releases.
For owners of HW3 vehicles (everything we know about the HW3 upgrade), this phased release means that they’ll be waiting a little longer than other owners, but at least there’s progress and some clear next steps now. A little more waiting isn’t too bad, especially when you consider just how long many owners in Australia and New Zealand have been waiting for any semblance of FSD in their nations. Tesla initially outlined Q2 2025 as the target availability date for FSD in RHD markets, so this timing is roughly on track with what Tesla initially announced in September 2024.
Hopefully, Tesla also opens up the opportunity for FSD transfer for HW3 owners in both countries, as we’re sure many people would upgrade alongside the official release of FSD to the latest hardware.
And just in case you thought the first video wasn’t true because it wasn’t upside down - well, Tesla provided us the original too.
Another quarter has passed, and that means it’s time to submit questions and vote for Tesla’s Q2 2025 Earnings Call. While Q1 was a tough quarter for the company, Q2 saw some recovery in sales, although there’s still some work to be done.
However, there’s always a lot to be excited about during Tesla’s Q&A session, where we usually learn a lot about future software improvements and upcoming vehicles. We may hear more about FSD Unsupervised, Robotaxi, or the more affordable vehicle, or its upcoming larger 6-seater Model Y, the Model Y L. Tesla also mentioned a potential FSD price hike back in the Q1 2025 Earnings Call, so that could be something that is brought up as well.
Tesla’s Q2 So Far
Tesla has already released their Q2 2025 Production and Delivery numbers, which were up from Q1 of this year, but still down compared to Q2 last year.

Top Questions So Far
Unsurprisingly, people have already been submitting questions, and here are the top ones so far.
Can you give us some insight how robotaxis have been performing so far and what rate you expect to expand in terms of vehicles, geofence, cities, and supervisors?
What are the key technical and regulatory hurdles still remaining for unsupervised FSD to be available for personal use? Timeline?
What specific factory tasks is Optimus currently performing, and what is the expected timeline for scaling production to enable external sales? How does Tesla envision Optimus contributing to revenue in the next 2–3 years?
Can you provide an update on the development and production timeline for Tesla’s more affordable models? How will these models balance cost reduction with profitability, and what impact do you expect on demand in the current economic climate?
Are there any news for HW3 users getting retrofits or upgrades? Will they get HW4 or some future version of HW5?
When do you anticipate customer vehicles to receive unsupervised FSD?
And here are some other ones we found interesting:
Have any meaningful Optimus milestones changed for this year or next and will thousands of Optimus be performing tasks in Tesla factories by year end?
Are front bumper cameras going to be necessary for unsupervised full self driving? If so, what is the companies plan to retrofit vehicles that do not have them?
Will there be a new AI day to explain the advancements the Autopilot, Optimus, and Dojo/chip teams have made over the past several years. We still do not know much about the HW4.
Earnings Call Details
Tesla will hold its earnings call on Wednesday, July 23rd, at 4:00 PM EDT. It's still early for an access link, but we’ll make sure we have a link up on the site before the earnings call that day.
If you do miss the earnings call, no worries. We will provide a full recap following the call, and we’ll also do some in-depth dives into what was said and what we know.
