Tesla shows battery manufacturing lines inspired by other industries in new video
Tesla has released a new one-minute long video spot on its YouTube channel, showing the company’s battery cell manufacturing lines. Elon Musk stated that some of the best manufacturing technology is present in other industries, inciting some curiosity that Tesla may have drawn inspiration from other sectors for its battery scaling projects.
It is no secret Tesla has put a major focus on manufacturing efforts. Whether involved in the manufacturing of the vehicle itself or the batteries that power it, Tesla has worked to improve production lines for a more efficient build process that will help the company scale quickly to handle demand increases.
The new video shows plenty of similarities between the cell production lines and what may be used at a Coca-Cola factory. Elon Musk acknowledged the strategies when a follower mentioned them to him. Owen Sparks, a Tesla fan and owner, noticed that Tesla’s battery cell production lines appeared to be similar to bottling processes used by large-scale beverage companies. Musk replied to the Tweet, acknowledging the similarities and commending high-volume industries for inspiring the Tesla battery lines.
“The best manufacturing technology is in high volume industries, like food & beverage, some medical (eg syringes) & toys,” Musk replied.

Battery cells are in high demand by many companies aiming to produce electric cars, but Tesla is going a step further. Even though the company sources its cells from Panasonic, LG Chem, and CATL, it aims to build its own batteries at the Kato Road facility near the Fremont factory. Musk detailed Tesla’s battery production efforts at its Battery Day event in September. Even though Tesla is sourcing from third-party suppliers currently, the company may eventually plan to phase it out to control pricing, create better margins through vertical integration, and control supply through demand expectations.

Tesla has gone as far as sourcing its own battery materials, and Musk even hinted that large Nickel mining companies should contact the automaker. The CEO offered a “giant contract” that would last for several years if a sustainable nickel miner came forward. Right now, Tesla’s suppliers are focusing on high-nickel batteries, attempting to relieve the dependency on cobalt.
The most expensive part of an electric vehicle is the battery pack, and longevity depends on battery quality. Tesla has attained a sizeable lead in the sector due to better battery quality and advanced EV tech, but there is always room for improvement. Moving forward, the company would like to mass-produce batteries to get to price parity with gas-powered vehicles. Tesla has laid out a plan with explicit details and claims it will release a $25,000 vehicle within a few years. This ultimately comes down to controlling battery costs, and if Tesla can figure out in-house cell scaling, it will be well on its way to cutting the price of its EVs by a significant margin.

Tesla has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
-
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
-
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
-
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled
— Dan Burkland (@DBurkland) July 27, 2026
Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
