Tesla's focus on batteries is being proven right, and other EV makers are paying the price
As more and more automakers begin the transition to electric vehicles, it is becoming increasingly apparent that Tesla’s intense focus on batteries was right all along. Tesla’s strategies have always been criticized and examined under a microscope, and the company’s decision to build Giga Nevada, a facility dedicated to battery production for the Model 3, was no exception. But as veteran automakers like Jaguar and Mercedes-Benz are now finding out, investing tons of effort and resources on batteries matters a lot.
Tesla is among the industry’s most vertically-integrated companies. Similar to Apple’s consumer electronics and SpaceX’s rockets, most of what goes inside a Tesla electric car is designed and built in-house. Tesla is so serious about this; the company actually made its own seats. The same is true for the electronics that goes inside every Tesla. They are so different and superior to off-the-shelf components that teardown expert Sandy Munro compared them to the electronics of a literal fighter jet.
A lot of Tesla’s resources are dedicated to its battery improvements. Teslas stand tall among their rivals in the EV marketplace today primarily due to their efficiency and range, and this is made possible by the company’s battery tech. The company is not showing any signs of stopping too. Tesla has acquired several companies that could further improve its batteries, such as Maxwell Technologies and Hibar Systems. The electric car maker is even looking to produce its own batteries, with reports indicating that work is already underway to develop custom cells for Tesla’s next generation of vehicles and products.
It’s a difficult pill to swallow, but veteran automakers have reached a point where they must honestly admit that when it comes to batteries, Tesla has a notable lead. The very representation for this idea is the Porsche Taycan, an otherwise excellent high-performance electric vehicle whose ~200-mile EPA range is an Achilles Heel. Porsche, similar to other EV makers, opted for off-the-shelf batteries for the Taycan, and it shows. The car performs beautifully, and it’s arguably the only EV that can beat a Model S fair and square in a race, but it simply does not have the range or the efficiency to beat Tesla’s flagship sedan on all metrics.
It’s not just about the battery tech and specific cell chemistries either. Over the years, Tesla also had the foresight to secure ample battery supply for its vehicles and products. From Panasonic, which has been Tesla’s partner since its early days, to CATL, which is the company’s partner for Giga Shanghai, the electric car maker has made careful preparations to ensure that its vehicles and products will always have enough batteries. Other EV makers are not as fortunate.
This is one of the reasons why the Jaguar I-PACE, one of the most decorated vehicles in modern auto history, actually stopped production for a week. Just like the Taycan, the I-PACE is actually a pretty decent EV, with its plush interior and aggressive exterior. But behind the I-PACE’s looks lies off-the-shelf batteries that are also used by other companies. This meant that when LG Chem could not supply enough cells for the vehicle, Jaguar had no choice but to stop the vehicle’s production temporarily.
The Mercedes-Benz EQC is in the same boat. Once deemed as a potential “Tesla Killer,” the EQC’s production target for 2020 was halved by the German automaker from 60,000 vehicles to just 30,000 units. The reason was something that is pretty familiar: Daimler just could not secure enough batteries. Even companies like Dyson and Aston Martin, both of which had plans to make EVs, eventually suspended their efforts to enter the electric car market.
Tesla is not a perfect company by any means. CEO Elon Musk would be the first to admit that the company has made many mistakes over the years. But for all its delays and production issues, there is very little that can be criticized about Tesla when it comes to its batteries and the company’s foresight in improving them and securing their supply for years to come.

Tesla FSD changed its mind mid-intersection, and it may have saved a life
Tesla shares dashcam footage of FSD Supervised stopping mid intersection to avoid a T-bone crash.
Tesla is putting another Full Self-Driving save in front of its 24.8 million followers on X.
On Tuesday morning, Tesla’s main account shared a dashcam clip with the caption “FSD Supervised preventing T-bone crash.” The footage came from an owner posting as TheNewGrid, who described what happened at a stop sign: “I looked at the car coming to the stop sign figured they would stop, my car went, then came to a stop mid intersection as they flew by. Had I been manually driving this would have resulted in a crash.”
The sequence is the notable part. FSD had already started crossing when the other driver ran the stop sign. Instead of pressing on, the car braked hard in the middle of the intersection and let the crossing vehicle pass in front of it. By the owner’s own account, they had made the same assumption the software initially made, that the other car would stop, and would not have corrected in time.
FSD Supervised preventing T-bone crash

The clip is the latest in a run of safety posts Tesla has amplified over the past several days. On Saturday, the company shared a video from Selling Sunset star Jason Oppenheim, who sold his Bentley for a Model Y and said he was buying Teslas with FSD for 10 of his employees. Ashok Elluswamy, who leads Tesla AI, followed up by writing that Tesla self-driving “reacts to other people cutting into your path with super-human response times.” On Monday, a Cybertruck owner posted footage of FSD moving across three lanes from a red light to clear a path for an ambulance approaching from behind.
This recent clip also lands a few weeks after Tesla began shipping Automatic Collision Evasion with FSD v14.3.9, a feature that can activate FSD on the driver’s behalf when a frontal collision is imminent or the driver appears distracted. Elluswamy said in September that “even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance” are coming with v15, the release Tesla has tied to round the clock Robotaxi operation.
The safety messaging matters beyond social media. Tesla has said FSD Supervised was 4.1 times less likely to crash than manual driving across 100 million kilometers on European roads, and it has been putting those figures in front of regulators. Eight EU countries have now approved FSD Supervised, with Croatia the most recent, but the EU’s bloc-wide vote originally set for October 6 has been pushed to December at the earliest.
FSD Supervised is still a Level 2 system, and the driver remains responsible at all times. Even heavy users find reasons to step in. Teslarati’s Joey Klender, who uses FSD for about 76 percent of his driving, laid out five recurring issues on Tuesday that still prompt him to intervene. Clips like this one show the other column of that ledger: moments where the software caught a mistake a human was about to make.

Tesla Model 3 and Model Y can now do what only Cybertruck could
Tesla Model 3 and Model Y can power your home with Powerwall 3 during outages.
Tesla has turned its two top sellers into backup batteries for the house.
Tesla Energy announced on Tuesday that Powershare Home Backup is now available for new Model 3 and Model Y vehicles paired with a Powerwall 3, saying the car can “extend your home backup by over 2 days.” Minutes later, Tesla’s main account quoted the post with a broader pitch: “With Powerwall 3, every Tesla can now serve as your home’s backup battery.”
Until this week, the Cybertruck was the only Tesla that could send power back into a home, and that capability only began working alongside Powerwall 3 last month, after years of ambitious targets.
Tesla’s updated Powershare page says every Model 3 and Model Y ordered in the U.S. or Puerto Rico on or after October 1, 2026 can use the feature. Some, but not all, earlier cars also qualify. Owners can check on the touchscreen under Software, then Additional Vehicle Information, where a capable car shows “Powershare Support: Enabled.” As Electrek reported, bidirectional power on the two cars runs through an inverter Tesla calls PCS2 Lite, and the company has not said when that part entered production on each trim.
The home side is simpler. A house that already has a Powerwall 3 and either a Wall Connector 3 or Universal Wall Connector needs no additional equipment, and Tesla says compatibility is enabled through a software update. When the grid drops, the Powerwall and the car work together, with up to 11.52 kW of continuous power available. Tesla’s “over two days” estimate assumes a home using 30 kWh per day and a car starting at a 90 percent charge. Standard trims are rated for up to two days, while the Cybertruck adds more than three.
There are limits. Powerwall 2 and Powerwall+ support is listed as “coming soon.” Model S and Model X are not included, and Grid Support, the program that lets Cybertruck owners in Texas send power back to the grid during demand spikes for bill credits, is not available for Model 3 or Model Y.
The rollout also lines up with something Elon Musk said more than three years ago. At Tesla’s March 2023 Investor Day, Musk said, “I don’t think very many people are going to want to use bidirectional charging, unless you have a Powerwall.” Tesla has now shipped the feature for its volume cars with exactly that requirement attached.
The Powerwall pairing was the hard part on Cybertruck. Tesla told owners in December 2025 that Powershare with Powerwall had been pushed to mid 2026, and lead engineer Wes Morrill explained that two devices capable of forming a home’s grid have to negotiate which one leads during an outage, across multiple generations of hardware. With that work done for the truck, Tesla was able to extend it to the Model 3 and Model Y within a month.
Ford and GM have offered home backup from their EVs for several years, but both require a separate inverter and backup hardware. Tesla’s version leans on equipment many Powerwall 3 owners already have on the wall. Powershare for the two cars also ships as part of software update 2026.38.3, the same release that began delivering Halloween Mode on Tuesday.
Tesla is now starting to ship a “Halloween Mode” that is filled with some creepy and fun features; the company says, “This spooky update turns your Tesla into a haunted house on wheels.”
The update is just the latest in a series of updates that Tesla typically ships out in a seasonal fashion. The Spring and Summer Updates provided some fun novelty items while also packing some cool features that are actually useful for the ownership experience.
This one seems to be more fun-forward, and there are not any updates to the Full Self-Driving suite or overall operation of the vehicle. Instead, these novelty features are geared toward getting you in the mood for the Fall and Halloween.
