Tesla’s Battery Day is coming tomorrow after the electric car maker’s 2020 Annual Shareholder Meeting. During the event, Tesla is expected to discuss the details of its next-generation battery cells, as well as their role in the world’s acceleration in sustainable energy. Actual details about Battery Day have been pretty scarce save for a few potential leaks, but that has not stopped the Tesla community from speculating about what the highly-anticipated event would involve.
A concise summary of the current expectations for Battery Day was recently shared by Tesla Daily’s Rob Maurer, who compiled a list of topics that the electric car maker could cover during the event. Following then is a list of expectations about what Tesla could discuss tomorrow, as the company finally shows the world what it has been working on with regards to its battery technology.
A New Cell Design
Tesla has been teasing that it would be going into the production of battery cells. So far, leaks suggest that the company is about to adopt a larger form factor for its batteries, similar to how Tesla introduced the 2170 cells for the Model 3, which were larger than the 18650 cells used in the Model S and Model X. Leaks have pointed to Tesla’s new cells possibly adopting a 54×98 form factor, which has about 10x the volume of a 2170 cell.
With larger form factors, the electrons and the ions travel larger distances as they move around in the cell, generating more friction and heat. This is a huge downside to larger cells, but Tesla’s tabless battery patent may hold the key to solving this issue. With a tabless battery cell design, the distance traveled by electrons and ions is largely reduced, limiting the disadvantages inherent among large cells. Such a design has several advantages, including better energy density and a more efficient manufacturing process.
Battery Chemistry
Speculations are abounding that Tesla may discuss the amount of silicon that it is using in the anode of its next-generation cells. The more silicon that is used, the better the energy density. However, the utilization of silicon usually results in cracked anodes over time, reducing battery performance and life. Introducing more silicon into the anode is something that battery researchers have been attempting to accomplish for a while now, so it would be quite interesting if the electric car maker would announce some headway into its silicon use as well.
-->Tesla may also discuss Maxwell’s technology and how it is being used for the company’s electric cars and energy storage devices. Maxwell has developed numerous innovations prior to its acquisition by Tesla, though the most relevant part of the company’s work in relation to the electric car maker is arguably its dry battery electrode tech. Considering that traditional lithium-ion batteries produce their electrodes in a wet slurry format (a rather lengthy process), dry electrode technology could vastly improve not only the energy density of Tesla’s cells, they could improve the production output of the batteries themselves as well.
Cell-to-Pack Innovations
Tesla’s battery packs today feature cells that are packed into modules that are then packed into a battery pack. Back in the days of the original Roadster, battery modules were used as a means for the company to take out parts of the battery that may need to be replaced without taking out the entire pack. That was 12 years ago, however, and much has happened since then. Tesla has transitioned from a budding niche electric car maker to the manufacturer of the market’s best-selling EVs.
As Elon Musk noted in the past, battery modules today are pretty much just an extra step, taking up weight without really serving a legitimate purpose. Musk then stated that the future is cell to pack without modules, suggesting that the company’s next-generation batteries will be using a cell-to-pack design. Such an innovation gives numerous benefits to Tesla, from lower production costs to possibly even better energy density.
Battery Manufacturing and the Roadrunner Line
Elon Musk has always been pretty transparent about Tesla’s mission, which is to accelerate the advent of sustainable energy. Having enough batteries to enable such a transition is key to this goal. With this in mind, the potential innovations that Tesla will be discussing in Battery Day — a larger form factor that would allow the company to produce fewer cells to get the same amount of energy; a tabless cell design that could make production easier; dry electrode tech that could greatly increase the production capacity density of each battery; and a cell-to-pack design that should allow the production of batteries with less equipment at less cost — could ultimately pave the way for electric vehicles and energy storage products that are significantly better than the industry standard today.
The Roadrunner project in Fremont is expected to be a central component of Tesla’s battery manufacturing plans, with attendees to the event being shown just how fast the company could produce its battery cells using its in-house production process. Elon Musk seems to be hyping the Roadrunner line recently on Twitter as well, when he made references to a game called “Factorio,” which happens to be a title focused on growing and maintaining advanced, efficient factories.
-->The Million-Mile Battery
The million-mile battery has been heavily speculated for Battery Day. Tesla’s electric cars are already capable of lasting long despite heavy use, but with batteries and powertrains that could last a million miles, the company could create a generation of vehicles that are designed to be always operational for an extended period of time. Million-mile batteries are then crucial for Tesla’s plans to roll out a Robotaxi service, which involves vehicles traveling long distances every year.
The Plaid Powertrain
With Tesla’s battery innovations in mind, speculations are high that the company would unveil its first vehicles that would carry its next-generation cells on Battery Day. Among Tesla’s ongoing projects, the Roadrunner cells seem to be a perfect match for cars like the Plaid Model S, Plaid Model X, and next-generation Roadster. All three vehicles have been confirmed by Elon Musk to feature the company’s upcoming “Plaid Powertrain,” which is something that has been heavily teased for some time now. Interestingly enough, updates on Tesla’s Plaid vehicles have been pretty scarce lately, making an announcement on Battery Day somewhat likely.

Tesla Full Self-Driving has warranted a huge switch-up on an essential company strategy as the automaker is hoping to increase the take rate of the ADAS suite.
Unlike other automotive companies, Tesla has long been an outlier, as it has famously ditched a traditional advertising strategy in favor of organic buzz, natural word-of-mouth through its production innovation, and utilizing CEO Elon Musk’s huge social media presence to push its products.
Tesla has taken the money that it would normally spend on advertising and utilized it for R&D purposes. For a long time, it yielded great results, and ironically, Tesla saw benefits from other EV makers running ads.
Tesla counters jab at lack of advertising with perfect response
However, in recent years, Tesla has decided to adjust this strategy, showing a need to expand beyond its core enthusiast base, which is large, but does not span over millions and millions as it would need to fend off global EV competitors, which have become more well-rounded and a better threat to the company.
In 2024 and 2025, Tesla started utilizing ads to spread knowledge about its products. This is continuing, as Full Self-Driving ads are now being spotted on social media platforms, most notably, X, which is owned by Musk:

Interestingly, Tesla’s strategy on FSD advertising is present in Musk’s new compensation package, as the eleventh tranche describes a goal of achieving 10 million active paid FSD subscriptions.
Full Self-Driving is truly Tesla’s primary focus moving forward, although it could be argued that it also has a special type of dedication toward its Optimus robot project. However, FSD will ultimately become the basis for the Robotaxi, which will enable autonomous ride-sharing across the globe as it is permitted in more locations.
Tesla has been adjusting its advertising strategy over the past couple of years, and it seems it is focused on more ways to spread awareness about its products. It will be interesting to see if the company will expand its spending even further, as it has yet to put on a commercial during live television.
We wouldn’t put it out of the question, at least not yet.
Tesla was nice enough to hook us up with the new Model Y “Standard” trim for a few days, and while we’ll be sure to fill you in on the full experience in the coming days, there are a lot of differences we noticed right off the bat, which make the ownership experience different from the “Premium” configuration level.
I purchased a Model Y Long Range All-Wheel-Drive back in August and took delivery just two weeks later. Through the first three months of owning my car, I’ve come to love so many things about the Tesla experience.
I traded my ICE vehicle for a Tesla Model Y: here’s how it went
However, I was interested in experiencing the affordable trim and seeing whether I would miss any of the voided features of the “Premium” Model Y.
Through the first 24 hours, here are my first impressions of the Model Y Standard as a Premium trim level owner:
Overall Aesthetic
The lack of a light bar is not something that is a dealbreaker. In fact, I would argue that the Model Y Standard’s more traditional headlight design is just as pleasing from an aesthetic standpoint.
The car is great looking from top to bottom; there are not a substantial number of differences besides the lack of a lightbar on both the front and the back of the car.
Overall, it is a very sleek vehicle, but the major changes are obviously with the interior.
Interior Changes
This is where the big differences are, and some of the things I’ve gotten used to in the Premium are not included. If I didn’t have a Premium Model Y already, I’m not sure I’d miss some of the things that are not present in the Standard trim, but I believe I’d get annoyed with it.
First impressions:
✅ Interior is excellent. I definitely miss the additional storage already that is available in my Premium. I could definitely get over it though
✅ Noticeable step down in sound system. Long Time by Boston absolutely cranks in the Premium; it’s still very… https://t.co/JNWvxTd8p1

Storage
The Premium has a large storage compartment between the cupholders and the wireless charger, which is not present in the Standard trim. Instead, it is more like the Cybertruck, as there is a pass-through and floor storage.
I think that the pass-through is nice, but the additional storage is something I take advantage of, especially as someone who films Full Self-Driving videos, which requires hauling mounts, GoPros, and other accessories.
The sleekness of the Premium trim is also something I prefer; I really enjoy having the ability to close those compartments and cover the cupholders.
Obviously, this is a really trivial issue and not something that is substantially impactful from an ownership experience. If I weren’t already an owner, I am not sure I’d even have something to complain about.
Material Differences
The Premium trim seats are completely Vegan Leather, which I really do like, even as someone who doesn’t really love leather seats due to their temperature dependency.
The Standard trim features a Textile and Vegan hybrid, which has half of the seat a different material than the other.
The material is very similar to what I had in my previous car, a Bronco Sport. It was very durable, easy to clean, dried quickly, and hid a lot of things that leather does not, like oils from your skin, which constantly require attention to keep your interior looking fresh.
The wireless charger is also a different material, as the Premium features an Alcantara material on that. The Standard has a rubberized and textured backing, which looks good, too. They’re both more than suitable.
Other Missing Features
The Standard lacks a few minor things, most noticeably is the ambient lighting. The biggest change, however, and something I really miss, is the glass roof.
A lot of people told me that when I got my Model Y, I wouldn’t even notice the glass roof after a few weeks. That could not be further from the truth. I look out of it all the time, and it’s one of my family’s favorite parts of the car.
My Fiancè and I really love parking and watching Netflix when we pick food up, especially when it’s raining, because the glass roof gives such a great view.
We also loved it as Fall arrived, because it was great to look at the foliage.
Buy the Tesla.
Enjoy the glass roof. pic.twitter.com/r2GDyOEEWu

Bigger Differences
There are also a handful of very noticeable differences from the overall cabin experience, especially with the sound system.
Much Weaker Sound System
The Model Y Standard has just 7 speakers and 1 amp, with no subwoofer. This is a significant step down from the 13-15 speakers in the Premium Long Range AWD Model Y, the 2 amps it comes with, and 1 subwoofer in the trunk.
I usually like to listen to Long Time by Boston to test out a sound system, and it was noticeably weaker in the Standard. It was missing a big portion of the umph that is provided by the Premium’s sound system.
Cabin Noise
It feels like the Cabin Noise is definitely more noticeable in the Standard, which is something I really love about my Model Y. It is able to dampen so much road noise from louder cars, and I don’t feel as if it is very quiet in the Standard.
This is perhaps the biggest make-or-break for me with this car. I truly have been spoiled by how quiet the cabin is in the Premium, and it’s due to the lack of acoustic-lined glass in the Standard.
I will be doing a more in-depth review of the Model Y Standard, especially with ride quality, later this week.

Tesla takes a step towards removal of Robotaxi service’s safety drivers
Tesla watchers are speculating that the implementation of in-camera data sharing could be a step towards the removal of the Robotaxi service’s safety drivers.
Tesla appears to be preparing for the eventual removal of its Robotaxi service’s safety drivers.
This was hinted at in a recent de-compile of the Robotaxi App’s version 25.11.5, which was shared on social media platform X.
In-cabin analytics
As per Tesla software tracker @Tesla_App_iOS, the latest update to the Robotaxi app featured several improvements. These include Live Screen Sharing, as well as a feature that would allow Tesla to access video and audio inside the vehicle.
According to the software tracker, a new prompt has been added to the Robotaxi App that requests user consent for enhanced in-cabin data sharing, which comprise Cabin Camera Analytics and Sound Detection Analytics. Once accepted, Tesla would be able to retrieve video and audio data from the Robotaxi’s cabin.
Video and audio sharing
A screenshot posted by the software tracker on X showed that Cabin Camera Analytics is used to improve the intelligence of features like request support. Tesla has not explained exactly how the feature will be implemented, though this might mean that the in-cabin camera may be used to view and analyze the status of passengers when remote agents are contacted.
-->Sound Detection Analytics is expected to be used to improve the intelligence of features like siren recognition. This suggests that Robotaxis will always be actively listening for emergency vehicle sirens to improve how the system responds to them. Tesla, however, also maintained that data collected by Robotaxis will be anonymous. In-cabin data will not be linked to users unless they are needed for a safety event or a support request.
Tesla watchers are speculating that the implementation of in-camera data sharing could be a step towards the removal of the Robotaxi service’s safety drivers. With Tesla able to access video and audio feeds from Robotaxis, after all, users can get assistance even if they are alone in the driverless vehicle.
