Former Tesla 4680 battery cell production engineer James Herbermann has been named Vice President of Manufacturing at the American Battery Factory (ABF).
“James brings to American Battery Factory incredible perspective and front row experiences in evolving battery cell technology and is the perfect complement to our team as we begin our journey to develop a domestic battery manufacturing ecosystem that will make energy independence and renewable energy a reality for the United States,” ABF CEO and President Paul Charles said. “As we lay the foundation for our factory network, I am confident James’ cross-functional leadership will not only enhance the efficiency of ABF’s modular approach to manufacturing, but it will also propel our unwavering quest to develop the longest-lasting LFP prismatic battery cells on the market.”
James Herbermann, formerly with Tesla, joins American Battery Factory as its new Vice President of Manufacturing.
ABF is working to develop the United States’ first network of Lithium-Iron Phosphate, or LFP, battery cell gigafactories. The LFP cell is a major part of many automakers’ plans for future electric vehicles as more cell chemistries are being utilized to combat excessive demand. Tesla, for example, started transitioning its Standard Range trim levels to LFP batteries last year. The automaker confirmed that it would utilize the cell chemistry in lower range vehicle as they are less expensive and have longer lifespans. They do have their disadvantages, especially in terms of energy density, which means less power and range with EVs that utilize these packs. They are also more likely to be affected by adverse weather conditions, especially in colder climates.
CEO Elon Musk has said in the past that LFP packs want to be charged to 100 percent, as opposed to nickel-based packs that prefer a 90 percent state of charge.
Tesla is just one of the companies working to use LFP cells. Rivian, Ford, and Volkswagen are also utilizing the cell chemistry for some of their vehicles. Therefore, the need to produce more cells to provide automakers and customers with suitable options is definitely a work in progress.

ABF is working to eliminate LFP shortages with a series of production plants across the U.S., and the company is looking for Herbermann to lead and support all aspects of its manufacturing and production operations. Prior to ABF, Herbermann worked at Tesla to lead the development and scaling of its new battery electrode processes in Austin from the pilot program to a full-scale production process. He was a direct piece of Tesla’s commercialization of the 4680 cells, which has been installed in early builds of the Model Y from the new Austin factory. Additionally, Herbermann has developed “novel Sodium Titanium Phosphate; F1 racing Li-Ion cells; Aquion Hybrid Ion (AHI®); Duracell Ultra®; Comfort Plus® modular carpet tiles; and ZIP Wall® sheathing,” a press release from ABF said.
“I am inspired by ABF’s mission to develop a domestic supply chain for LFP batteries, especially in light of the pandemic’s crippling effect on availability and our country’s glaring void in battery cell manufacturing,” Herbermann said about his new role. “With its strategic approach of constructing a network of modular rapid construction factories near or onsite at pack integrators and energy solution providers, ABF is on track to solve one of the planet’s most pressing energy needs. I look forward to being a part of this impactful work.”

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.
