Tesla’s 400-mile Model S is a subtle update, but it’s a chilling reminder to rival carmakers
There is a particularly interesting trend happening in the electric vehicle sector. While it is undeniable that Tesla is leading the industry’s shift to EVs, veteran carmakers are prone to claim that they have or are developing technology that is at par or superior to the electric car maker’s innovations. The Tesla Model S’ 402-mile EPA rating subtly sends a message that this is not necessarily the case.
For some time now, there has been a lot of talk surrounding Tesla and its upcoming Battery Day event. The company has been pretty thin on the specifics of the event, but speculations are abounding that discussions will be held surrounding the company’s next-generation batteries. Tesla has not formally hinted at the details of these batteries, though all signs point to cells that would be able to last a million miles. Discussions about other innovations such as cobalt-free cells for China-made Model 3s are also expected to be held at the event.
Similar to how vehicles like the Porsche Taycan and the Audi e-tron were dubbed as “Tesla Killers” in previous years, veteran automakers such as GM appear to be keen on establishing the idea that it is not being left behind in the EV race. Just last month, for example, GM Executive Vice President Doug Parks stated that the automaker’s own “million-mile” battery is “almost there.” Parks stated that there are multiple teams within GM that are working on zero cobalt batteries as well.
Such statements from GM only validate Tesla’s points about electric vehicles. The fact that the veteran automaker’s battery plans seem to be inspired, at least in some way, by the younger EV maker means that the auto industry has now reached a point where electric powered transportation is a given. That being said, there is very little doubt that the Model S’ updated EPA ratings, which show that the 100 kWh flagship sedan could go 402 miles on a single charge, is likely sending some chills down the spine of Tesla’s rivals.
As noted by Tesla CEO Elon Musk, every Model S that has been produced since January has been equipped with a 402 mile range. This feat, as stated by the company in an announcement on its official website, was accomplished through a variety of means, including significant mass reduction, new aero wheels that optimize efficiency, increased drive unit efficiencies, and optimized regenerative braking.
What this means is that Tesla was able to draw out 400 miles of EPA range from a 100 kWh battery pack using its current battery technology. The 400-mile Model S today is just a hyper-optimized version of the Raven series that came out last year. Unless Tesla states otherwise on Battery Day, it appears that the current generation Raven Model S is not yet equipped with the company’s next-generation million-mile batteries.
It should be noted that other companies have pledged to release vehicles with a range of 400 miles as well. Electric pickup maker Rivian’s flagship R1T pickup truck goes 400 miles too, but that vehicle is equipped with a 180 kWh battery pack. The GMC Hummer EV, widely speculated to be a legitimate competitor to the Tesla Cybertruck, is also poised to be released with a 400-mile range. But just like the Rivian R1T, there’s a good chance that its battery pack will be substantially bigger than the 100 kWh pack used in Tesla’s flagship sedan.
Of course, it would be easy to argue that larger vehicles like the Rivian R1T and the GMC Hummer EV would obviously need more batteries due to their size, but it should be noted that Tesla’s Cybertruck, which will likely have a battery that’s far larger than the Model S’ 100 kWh pack, has some impressive range as well. During its unveiling, Elon Musk noted that the all-electric pickup’s tri-motor variant will have over 500 miles of range. The specifics of the Cybertruck’s battery have not been disclosed by Tesla yet, though it is almost certain that it will be utilizing the company’s million mile battery cells.
So what does this mean for the Model S? With a million-mile battery and a 100 kWh pack, the flagship sedan’s succeeding generations will most likely achieve a range estimate that’s even more impressive than its current 402-mile EPA rating. And this, ultimately, is something that will be very hard to meet or compete with, especially among veteran automakers that have not dedicated the same amount of time and effort into developing battery technology from the ground up.

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.

SpaceX reveals how its 1 Million AI satellite network will work and prevent space collisions
SpaceX reveals plans for one million Starmind AI satellites and calls out operators hiding maneuvers.
SpaceX has put the largest satellite count it has ever published into writing, and it says that plan only works if every other operator in orbit starts sharing what it knows.
In a new Space Safety page highlighted Tuesday morning by Sawyer Merritt on X, SpaceX said it “plans to operate up to 100,000 Starlink satellites and up to 1 million Starmind AI satellites to meet the growing demand for broadband and supercompute.” Starlink has a little over 11,000 satellites in orbit today, so the target alone implies roughly a ninefold expansion of the broadband network.
Starmind is SpaceX’s orbital AI compute constellation. Elon Musk confirmed the Starmind name in June after an xAI trademark filing surfaced, and in August SpaceX said it was working with Nvidia on the compute payload. The FCC accepted the filing for up to one million satellites back in February.
FCC accepts SpaceX filing for 1 million orbital data center plan
SpaceX also released a new render of what a full Starmind constellation could look like. Alongside it, SpaceX VP Michael Nicolls explained why the satellites will not operate on their own. “We need to operate clusters of satellites in tight formation to get enough coherent compute to run AI models efficiently,” Nicolls said. “A cluster will be 10-ish satellites connected with 10 terabits or so of bandwidth between them, and interconnected to the broader constellation.”
That is the most specific detail SpaceX has given on how Starmind will be built. Instead of a million independent servers, the network would work as tightly packed groups of about 10 satellites acting as one compute unit, with Starlink’s laser links carrying results back to Earth.
There is a bright and exciting future for humanity ahead – and space is fundamental to that future.
To achieve this, space safety must be done right. We encourage every operator to not only share ephemeris data proactively the same way Starlink already does, but to also adopt the high standards of space safety that SpaceX and Starlink use every day → https://t.co/QizAkQZvEm

Packing satellites that close together, at that scale, makes collision avoidance the central problem, and most of the Space Safety page is aimed at other operators. SpaceX said Starlink encountered collision risks with about 650 unique maneuvering third party satellites in 2026, and only about half of them shared data. Over six months, Starlink recorded roughly 164,000 more collision risks where the closest approach came within four hours of an unannounced maneuver.
Some operators keep maneuver plans private over proprietary concerns, while others cannot get government permission to share them. SpaceX called those policies “counterproductive,” saying they “largely only serve to create preventable collision risk between satellites.” Starlink is also offering a free ephemeris sharing and screening platform that returns risk results within a minute, backed by its Stargaze network of 30,000 optical sensors.
The push comes as the Starmind application draws opposition from astronomers and environmental groups. In a September filing with the FCC, SpaceX said each Starmind satellite could weigh up to 4,000 kg, nearly seven times the mass of a Starlink V2 Mini. Musk has brushed off crowding concerns before, telling viewers in June that “space is enormous” and that SpaceX already knows how to run very large constellations safely.
SpaceX’s Starmind page says its Gigasat factory in Bastrop, Texas, is designed to produce AI satellites at scale, with deployment of thousands of units starting as soon as late 2027.
