Tesla Battery Day can mean doomsday for legacy carmakers shifting to electric
Tesla is expected to hold its Battery Day in April as Elon Musk announced during the company’s Q4 earnings call. The chief executive said the company has a “compelling story” to tell about things that can “blow people’s minds.” These statements do not only pique the interest of the electric vehicle community; they also hint of updates that can spell disaster for legacy car manufacturers trying to catch up with Tesla in the electric vehicle market.
Batteries are key to staying on top of the electric vehicle segment and Tesla is the leader of the pack when it comes to batteries and energy efficiency. This has been validated by organizations such as Consumer Reports and even by competitors who go deep into their pockets and go as far as cutting their workforces to catch Tesla in terms of hardware, software, and battery technology.
Come Tesla Battery Day, the obvious would be made more obvious. Tesla could further widen the gap and set itself apart from the rest, not just as the maker of the Model 3, Model Y, Cybertruck or other vehicles in its lineup but as an energy company.
Mass Production Of Cheaper Batteries
Batteries are among the most expensive components of an electric vehicle. This is true for Tesla and other electric vehicle manufacturers. With pricey batteries, car manufacturers cannot lower prices of their vehicles and therefore cannot encourage the mass adoption of zero-emission cars.
Tesla has reportedly been running its “Roadrunner” secret project that can lead to mass production of battery cells at $100/kWh. According to rumors, Tesla already has a pilot manufacturing line in its Fremont facility that can produce higher-density batteries using technology advancements developed in-house and gained through the Maxwell acquisition. With a $100/kWh battery, the prices of Tesla’s vehicles can be competitive even without government subsidies.
Aside from the Roadrunner project, Tesla has also been setting itself up to succeed in the battery game and dominate the market with its partnerships. It has a long relationship with Panasonic that helped it manufacture batteries in Giga Nevada, but has also signed battery supply agreements with LG Chem and CATL in China.
Battery prices have been going down significantly in the last decade. According to BloombergNEF, the cost of batteries dropped by 13% last year. From $1,100/kWh in 2010, the price went down to around $156.kWh in 2019. This is predicted to come close to the target $100/kWh by 2023. If Tesla achieves the $100/kWH cost sooner than the rest, it will give the company a massive advantage over its competitors and that will eventually lead to better profit margins.
Aside from cheaper batteries, the increased battery production capacity is also key in bringing products such as the all-electric Cybertruck and Tesla Semi to life.
“The thing we’re going to be really focused on is increasing battery production capacity because that’s very fundamental because if you don’t improve battery production capacity, then you end up just shifting unit volume from one product to another and you haven’t actually produced more electric vehicles… make sure we get a very steep ramp in battery production and continue to improve the cost per kilowatt-hour of the batteries,” Musk said during the Q4 2019 earnings call.
Enhanced Tesla Batteries
Tesla already has good batteries through its years of research, experimentation, and partnerships with battery producers. It has invested a good amount of money and effort to make sure it’s leading the battery game.
This advantage is made very clear on how Tesla was able to produce the most efficient electric SUV today in the form of the soon-to-be-released Model Y crossover with an EPA rating of 315 miles per single charge versus the Porsche Taycan with a range of around 200 miles.
With the acquired technologies from companies such as Maxwell and recently a possible purchase of a lithium-ion battery cell specialist startup in Colorado, Tesla demonstrates it’s not stopping its efforts to perfect its battery technology. Maxwell manufactures battery components and ultracapacitors and it’s just a matter of time before Tesla makes use of these technologies.
When asked about Maxwell’s ultracapacitor technology during the Q4 2019 earnings call, Musk said, “It’s an important piece of the puzzle.”
Musk also referenced the Maxwell acquisition during an extensive interview at the Third Row Podcast. “It’s kind of a big deal. Maxwell has a bunch of technologies that if they are applied in the right way I think can have a very big impact,” Musk said during a Third Row Podcast interview.
There are rumors out of China claiming that Tesla may come up with a battery that combines the best traits of Maxwell’s supercapacitors and dry electrode technologies. This could mean batteries that could charge faster, pack more energy density, and last longer.
Controlling Battery Supply
Knowing what works and what doesn’t for electric car batteries puts Tesla on top of the game. Of course, add to that what could be the best battery management system that makes Tesla vehicles among the most efficient if not the best in utilizing their batteries. With the advantage on hardware and software fronts, the thought of Tesla becoming a battery supplier is far from being a crazy idea.
Its competitors such as Audi and Jaguar have recently expressed concerns about their battery supplies as they both depend on LG Chem. Tesla– aside from its partnerships with Panasonic, LG Chem, and CATL — pushes the limit to develop its new battery cells in-house and that opens up a lot of possibilities for Tesla as a business.
“It would be consistent with the mission of Tesla to help other car companies with electric vehicles on the battery and powertrain front, possibly on other fronts. So it’s something we’re open to. We’re definitely open to supplying batteries and powertrains and perhaps other things to other car companies,” Musk was quoted as saying.
Recent job postings for a cell development engineer and equipment development engineers suggest that Tesla might actually be considering the idea of introducing a battery line of its own. But of course, the next-generation batteries would be first used for its vehicle lineup. Once it meets that demand and hits economies of scale, one can only imagine how Tesla could play the important role of supplying batteries to other carmakers.
Whether Tesla would announce cheaper batteries, enhanced electric car batteries, or give updates about its efforts, Battery Day in April will most definitely be worth the wait. For other car manufacturers, time would pause during that day as they listen to what Elon Musk and his team will say. And most likely, after the company talk, other car manufacturers will have to go back to their drawing boards once more in an attempt to catch up.
Tesla is bolstering its Cybercab fleet with the State of Texas’s regulatory bodies ahead of the planned launch of the all-electric ride-hailing vehicle this Thursday.
Seven purpose-built Tesla Cybercabs have been added to Texas’s official automated vehicle registry, appearing in the Texas Motor Carrier Credentialing System (TxMCCS) public lookup just three days before Tesla’s invite-only Cybercab launch event in Austin on September 3.
The records, visible through TxDMV’s Motor Carrier and Automated Motor Vehicle Operator Lookup, list seven 2026 Tesla Cybercabs under Tesla Robotaxi, LLC. Their VINs begin with the 5YJA prefix, distinct from the 7SAYG Model Y robotaxis that already dominate Tesla’s Texas fleet.
Community trackers that scrape the same public database recorded the new entries on August 31, bringing Tesla’s authorized Texas robotaxi total to 276 vehicles: 269 Model Ys and the seven Cybercabs:

Texas Senate Bill 2807, which took effect in late May 2026, created a self-certification framework for commercial Level 4 operations. Operators file through TxMCCS, attest to SAE Level 4 capability, maintain insurance, and keep an active vehicle list.
Tesla completed that process months earlier for its existing Model Y Robotaxi service, which has carried paying passengers in Austin, Dallas, Houston and other markets. Adding the Cybercabs to the same authorization means the new two-seat, steering-wheel-free vehicles are now legally recognized for commercial use on Texas roads.
The timing is deliberate as Tesla scheduled the September 3 event at its Austin campus after sending invitations to selected Robotaxi riders and other guests. The company has described the evening as a chance to “experience the future of full autonomy” and plans to livestream it.
Production Cybercabs, which lack pedals and a steering wheel, have been rolling off the Giga Texas line for months; some earlier examples still carried temporary driver controls for data collection. Registering a small fleet of the finished design immediately before the public event signals that Tesla intends to move the purpose-built vehicle from factory and test tracks into the same Robotaxi app already used by Model Y passengers.
The seven units remain a tiny fraction of Tesla’s overall Texas authorization and far smaller than competing fleets. Registration does not automatically equal unsupervised public rides; it is the legal prerequisite.
Still, the sudden appearance of Cybercab VINs in the state’s lookup system, after a year of Model Y-only listings, is the clearest official confirmation yet that Tesla’s dedicated robotaxi hardware is entering the regulatory pipeline at the same moment the company is preparing to show it to invited guests and a global livestream audience.
Whether those seven vehicles appear at the September 3 event or begin carrying passengers shortly afterward, their presence in TxMCCS marks a concrete regulatory step that has been anticipated since the Cybercab concept was first revealed.
Tesla has expanded the operational geofence for its driverless Robotaxi service in Austin, Texas, marking the first such increase in some time. The updated Service Area for Robotaxi in Austin now spans about 288 square miles and is roughly 9 percent larger than the previous boundary.
This incremental growth adds approximately 24 square miles of coverage, bringing the prior zone of roughly 264 square miles into a broader footprint that better serves northern suburbs.
The expansion extends the geofence northward toward Pflugerville along the US 183 corridor, incorporating additional neighborhoods north of the Domain and areas such as Mesa Park. These additions include higher-end residential and commercial districts that previously sat just outside the allowed operating zone.
Riders can now request unsupervised trips that begin or end in these newly included locations, provided the entire route remains inside the digital boundary:

Tesla first launched public Robotaxi operations in Austin in mid-2025 with a modest initial zone of about 20 square miles. Subsequent enlargements in 2025 and early 2026 steadily grew the map until it covered much of the metropolitan area.
After the last major update roughly ten months earlier, the company held the boundary steady while it collected additional miles and refined the FSD suite.
The modest nine percent increase still matters for daily utility. Longer trips become possible, more residents gain access, and the fleet can accumulate more diverse real-world data across new road types and traffic patterns. Observers note that the added territory aligns with existing Tesla service infrastructure, which could support more efficient vehicle staging in the North end of Austin.
Although the geofence has grown, Tesla continues to operate a relatively small unsupervised fleet in the city. The company has emphasized safety and software readiness over rapid geographic scaling. This latest map update signals that Tesla remains committed to expanding Robotaxi availability in its home market as it prepares for further software improvements and potential Cybercab deployments.
The 288-square-mile zone now gives Austin riders one of the larger driverless service areas currently available in the United States.
Tesla’s 2026 Summer Update turns Grok from a talking companion into a true in-car controller, with considerably expanded capabilities. Where the assistant once answered questions and handled navigation, it can now operate hardware and software through ordinary speech, including several requests at the same time.
Grok has become incredibly robust over the past few quarters, and this new ability that Tesla has included with its Summer Update is perhaps the clearest sign of just how capable it has become.
You can issue many commands to Grok at once, and each will be taken care of: anything from headlight control to climate adjustments to mirror folding can now all be taken care of with a simple sentence spoken toward Grok:
This is cool, you can now give Grok a ton of commands at once in your Tesla and it’ll do them all together.
The commands I gave:
• Fold mirrors
• Turn on wipers to fastest setting
• Change temp to 65°
• Open self-driving app
• Open gloveboxComes with Tesla’s 2026 Summer… pic.twitter.com/drZxoHrknv

Here’s another example I used in my Model Y:

Tesla’s official Release Notes list the core powers of Grok’s new capabilities: Grok can place phone calls from a paired phone, search a streaming service and queue music, adjust climate, and search the Controls panel. Drivers can also ask it questions about the vehicle or the latest features included in a recent software update.
It can also take care of driving settings, dynamics, and other relevant preferences that deal with how the car operates and handles.

It’s also more of a use case than a novelty feature. Grok was great for learning about something that was being pondered while Full Self-Driving was taking care of the major automotive responsibilities, but it did have some useful functionality when it came to navigation.
Another less-noted improvement is the swift transition that Grok has from thinking of its answer to giving you one. In the past, it would take a few seconds for Grok to truly come up with a valuable response. It now seems that it is improving, at least slightly.
