Tesla’s 75 kWh battery pack removal opens doors to ‘Track Mode’ for Model S & X
In a recent update on Twitter, Elon Musk announced that Tesla would be discontinuing the 75 kWh variants of the Model S and Model X. Starting this coming Monday, Tesla’s two flagship vehicles would only be offered at 100 kWh and 100 kWh Performance versions, widening the price gap between the cars and the company’s newest offering — the Model 3.
In a way, retiring the 75D line seems to be the right decision for Tesla. After all, the Model S 75D, which is priced at $76,000 before options, pretty much overlaps with the price of a fully-loaded Model 3 Performance. That said, this change also results in the base price of the Model S and Model X increasing significantly. The Model S 100D — the vehicle’s base version starting Monday — would start at $94,000, while the Model X 100D would start at $97,000, far higher than the Model X 75D’s starting price of $82,000.
Starting on Monday, Tesla will no longer be taking orders for the 75 kWh version of the Model S & X. If you’d like that version, please order by Sunday night at https://t.co/46TXqRJ3C1

Apart from widening the gap between the more affordable Model 3 and the flagship Model S and X, though, the retirement of the 75 kWh battery pack also opens the doors to a very likely battery upgrade for the full-size sedan and SUV. The Model S and X, after all, are still equipped with 18650 cells, which are smaller and a bit older than the 2170 cells being used on the Model 3. These cells are also imported from Panasonic’s facilities in Japan, instead of being produced in Gigafactory 1.
By retiring the 75 kWh battery pack, Tesla would give itself an opportunity to roll out the newer cells to its flagship vehicles. The 2170 cells, for one, would probably even allow the Performance-branded Model S and X to handle extended track driving. Part of the reason behind the current generation Model S and X’s inability to be competitive on the track, after all, is their batteries, which have a tendency to overheat after a few laps around a closed circuit. This particular issue has been largely addressed by Tesla with the Model 3 and its 2170 cells, as evidenced by the vehicle’s dedicated Track Mode setting.
A Track Mode feature for the Performance Model S and X would make the vehicles even more fearsome than they already are. Even with their general inability to be driven on a racecourse, the Model S and Model X have nonetheless developed a reputation as monsters in straight-line races over the years. Equipped with a battery that has the same tech as the Model 3 — from its 2170 cells to its clever cooling systems — the Model S and X would be downright frightening.

Apart from opening the doors to Track Mode, an update to 2170 cells would likely result in more range for the Model S and Model X as well. This is something that Tesla could definitely use as a selling point for its flagship vehicles, considering that the competition, including the Porsche Taycan and the Jaguar I-PACE, are still pretty much competing against the bar set by vehicles that were created during the 18650 cell era. One can only speculate how much range a Long Range version of the Model S would have if it were equipped with 2170 cells. Perhaps even a 400-mile range? Such a scenario is plausible.
Hidden within this new update from Elon Musk, though, is something that bodes well for the company’s upcoming vehicle — the Model Y. Seeing as Tesla retired the Model X 75D, the company’s only SUV in its lineup now starts at $97,000. That’s very expensive, and this price notably reduces the size of the vehicle’s potential consumer base in an incredibly popular segment. By adopting this strategy at this point, Tesla appears to be hinting at the release of another, more affordable SUV that can compete more aggressively than the entry-level Model X. This vehicle, of course, would be the Model Y.
The Model Y has been in the rumor mill for some time now. In recent months, though, Elon Musk has provided a number of updates on the vehicle. During the company’s third-quarter earnings call, for one, Musk mentioned that he had already approved the construction of the Model Y’s alpha prototype. Musk has also joked that the upcoming SUV would be unveiled this 2018, perhaps sometime in the first half of the year.

SpaceX brings four astronauts home after 8 months in space, and the return was flawless
SpaceX Crew Dragon Freedom returned four Crew-12 astronauts home after 237 days aboard the station.
Four Crew-12 members are back on Earth after 237 days at the International Space Station. SpaceX’s Crew Dragon Freedom splashed down in the Pacific Ocean about 50 miles west of Los Angeles at 11:34 a.m. ET on Thursday.
NASA astronauts Jessica Meir and Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev landed one day after undocking from the station’s Harmony module at 8:05 a.m. ET on Wednesday. NASA confirmed the splashdown minutes later. SpaceX had flagged the 27.5 hour trip home on X while Dragon was still firing its departure burns away from the station.
The descent ran on schedule when Freedom started a nine minute deorbit burn at 10:46 a.m. ET, then hit the thicker atmosphere about 36 minutes later at nearly five miles per second. Chutes deployed at around 18,000 feet, and four main parachutes brought the capsule down to roughly 15 mph at splashdown.
SpaceX fast boats secured Dragon before the recovery ship Shannon hoisted it onto the deck with the crew still inside. Flight surgeons on board ran initial medical checks. All four crew members will be flown ashore by helicopter and then head to NASA’s Johnson Space Center in Houston for rehabilitation.

Crew-12 launched on February 13 from Space Launch Complex 40 at Cape Canaveral, a flight that also marked the first Falcon 9 booster landing at SpaceX’s new LZ-40 pad. Over the mission, the crew completed 3,792 orbits, covered nearly 101 million miles, and carried out four spacewalks to maintain and upgrade the station.
Meir now has 440 cumulative days in space, which places her in NASA’s top 10. This was the first spaceflight for Hathaway and for Adenot, a French Air Force colonel and former helicopter pilot. Fedyaev, who spent 186 days in orbit on Crew-6 in 2023, has now flown two long duration Dragon missions.
The return closes out a busy stretch of Dragon traffic. Crew-13 arrived on October 1 aboard Crew Dragon Grace, which docked just 7 hours and 55 minutes after liftoff, the fastest launch to docking of any U.S. spacecraft in ISS history. Commander Jessica Watkins, pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and cosmonaut Sergey Teteryatnikov remain aboard alongside the three person Soyuz MS-29 crew.
With Crew-12 gone, the port is clear for CRS-35, a cargo Dragon carrying the final pair of ISS Roll-Out Solar Arrays. NASA is holding a post-splashdown teleconference at 1:15 p.m. ET covering both the crew’s return and the upcoming cargo launch.

Elon Musk shuts down talk of TSMC taking over Terafab
Musk says Tesla and SpaceX will build and run Terafab, with TSMC limited to renting.
Elon Musk has drawn a firm line around who will be in charge of Terafab, the giant chip factory Tesla and SpaceX are planning in Texas.
Musk replied to a post on X arguing that Taiwan Semiconductor Manufacturing Company (TSMC) would most likely end up owning and operating the plant. “No, we will build and run the fab. Let there be ZERO doubt about that,” Musk wrote. “Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.”
In plain terms, a sublease means TSMC could rent a section of the complex to make chips, similar to a tenant renting one floor of an office tower. The building, the equipment decisions and the daily operation would stay with Tesla and SpaceX.
@herbertong @thejefflutz No, we will build and run the fab. Let there be ZERO doubt about that.
Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.
— Elon Musk (@elonmusk) October 7, 2026
The comment shuts down speculation that started last week. On October 2, tech journalist Tim Culpan reported that TSMC was exploring ways to help run Terafab’s factories. Musk responded the next day that it was “just discussions, but something may come of it,” as Teslarati reported at the time. That left room for a scenario where the world’s largest contract chipmaker took the wheel. Musk’s latest post closes that door.
Some background helps explain why this matters. Tesla designs its own AI chips today but pays outside companies like TSMC and Samsung to manufacture them. Musk unveiled Terafab in March as a joint project between Tesla, SpaceX and xAI, arguing that existing suppliers cannot expand fast enough to meet his companies’ future demand. The goal is to produce enough chips each year to supply one terawatt of computing power, roughly 50 times what the entire global AI chip industry produces now.
Those chips are meant for Tesla’s Optimus humanoid robots, the Cybercab and Full Self-Driving computers, along with chips for SpaceX’s planned data centers in orbit. Owning the factory means Musk’s companies would not have to compete with every other chip customer for time on someone else’s production lines.
Intel is still part of the picture. The company signed on in April to help design, build and package chips for the project, and CEO Lip-Bu Tan told Bloomberg this week that Intel will keep working on Terafab despite the TSMC chatter.
The project moved from concept to construction planning over the summer. In August, SpaceX confirmed the Grimes County site about an hour from Houston, sent the county a $10 million payment under its tax abatement deal and said civil work would begin shortly. The first phase carries a $16.8 billion price tag, and total spending across all phases could reach as much as $119 billion.
TSMC chairman C.C. Wei has said a new fab typically takes two to three years to build and another one to two years to reach full output. Tesla and SpaceX have never run one, which is why TSMC’s expertise drew so much attention. Musk’s answer suggests he would rather learn that process in house than hand control of a project this central to Tesla’s robotics and autonomy plans to an outside company.
Terafab Texas will be the largest and most valuable building on Earth by far.
And it will be stunningly beautiful. https://t.co/4NweOqTL7y

Trump to hand Elon Musk a top honor that traces back to JFK
Trump will award Elon Musk the National Medal of Science at Thursday’s White House summit.
Elon Musk is set to receive the highest honor the U.S. government gives to scientists and engineers.
President Donald Trump will present Musk with the National Medal of Science on Thursday at the White House’s Science: A New Golden Age Summit, Fox News Digital first reported on Wednesday. Google cofounder Sergey Brin, Nvidia CEO Jensen Huang and AMD CEO Lisa Su will receive the same medal, while Dell Technologies CEO Michael Dell and Microsoft CEO Satya Nadella will receive the National Medal of Technology and Innovation. A White House official later confirmed the list to Reuters.
“The Trump administration is grateful for the contributions of these incredible leaders in science and technology. These recipients are helping ensure America keeps leading the world in innovation,” White House spokesperson Liz Huston told Fox News.
FIRST ON FOX: Trump will award Elon Musk the National Medal of Science at the White House Thursday.
Sergey Brin, Jensen Huang and Lisa Su will also receive the science medal, while Michael Dell and Satya Nadella will receive the technology medal.
It marks Trump’s first time presenting the awards across either administration.

It will be the first time Trump has presented either medal in his two terms. Congress created the National Medal of Science in 1959, and the National Science Foundation, which administers it, says 529 scientists and engineers have received it since. A presidential committee reviews nominees, but the president makes the final call.
Thursday’s group of medalists run or founded companies, and three of them sit at the center of the Super Intelligence hardware race that Musk competes in. Huang’s Nvidia supplies the GB300 chips filling SpaceX’s Colossus 2 cluster, while Su’s AMD is Nvidia’s biggest rival in data center GPUs.
Worth noting that Trump’s uncle, MIT physicist John G. Trump, received the National Medal of Science from President Ronald Reagan for his work on ionizing radiation and its uses in medicine and industry.
The Pentagon taps Elon Musk to design the battlefield of the future
For Musk, the medal is the latest sign of how far his relationship with Trump has come since their 2025 split over the “Big Beautiful Bill” and his exit from DOGE. Last week, he sat at Trump’s left during a White House lunch where AI executives signed a voluntary safety accord, and Defense Secretary Pete Hegseth named him to help lead the Pentagon’s Project Meridian study on the future of warfare. Musk has also adopted the administration’s new vocabulary, saying on Sunday that SpaceXAI will be renamed SpaceXSI after Trump ordered federal agencies to replace “artificial intelligence” with “super intelligence.”
Musk has collected science honors before, including the Stephen Hawking Medal for Science Communication in 2019.
