Other automakers follow Tesla into rare earth metal-free powertrains
Tesla and others are looking to end the use of rare earth metals in future electric vehicle (EV) motors, with U.S., European and Japanese automakers all considering the move to help reduce reliance on China.
During the company’s Investor Day event earlier this year, Tesla’s Vice President of Powertrain Engineering Colin Campbell announced that the company’s next-generation powertrain would include a permanent magnet motor with zero rare earth metals. Automakers including General Motors (GM), Jaguar Land Rover (JLR), Nissan and more, along with the supplier BorgWarner, are all developing, researching or have already created motors with low- or zero-rare earth materials, according to a recent report from Reuters.

Nissan has taken its attempts further than previously reported in the development of new magnet-free externally excited synchronous machine (EESM) motors, which utilize an electrical current to create a magnetic field. Eventually, the Japanese automaker plans to phase out the use of rare earth metals entirely through EESM development and the use of permanent magnet motors. Nissan also currently utilizes an EESM motor in the Ariya crossover.
“This is an important contribution to making us a little more independent of China,” said Otmar Scharrer, CTO of German supplier ZF.
ZF has created an EESM motor that Scharrer said offers similar performance and overall size to those in permanent magnet motors.
Currently, the processing and mining of the 17 minerals known as rare earth metals are dominated by China, and many have sounded the alarm on relying too heavily on the country — especially after the government announced a recent export ban of gallium and graphite, both of which are crucial for EV production.
There are also sustainability reasons to move away from the use of these minerals, along with those related to bolstering the home supply chains of individual markets. Other rare earth materials like neodymium and dysprosium require the use of solvents and generate toxic waste, opposing current environmental standards and goals.
Detroit-based company Drive System Design is working on motors free of rare earth metals with three different automakers, and the firm’s Director of Engineering Business Development, Ben Chiswick, also highlights the environmental benefits of the shift.
“If you get it right, you’ve got a much more sustainable product,” Chaswick said.
BMW has reportedly conducted several years of research into motors without rare earth materials.
“It was not a home run… but it works very well without rare earths,” said Uwe Deuke, BMW’s lead engineer for the EESM motor being developed for its next-generation vehicle.
Even automakers that aren’t phasing out rare earths entirely are reducing their content dramatically in upcoming EV designs. Mercedes-Benz, for example, will use almost no heavy rare earth materials in its next-generation EV, although it will still be a permanent magnet motor using a small amount of the minerals.

SpaceX posts Starship booster feat that’s so nutty, it doesn’t even look real
The Super Heavy booster’s feat was so impressive that the whole maneuver almost looked like it was AI-generated.

SpaceX has shared a video of a remarkable feat achieved by Starship’s Super Heavy booster during its 11th flight test.
The Super Heavy booster’s feat was so impressive that the whole maneuver, which was captured on video, almost looked like it was AI-generated.
Super Heavy’s picture perfect hover
As could be seen in the video shared by SpaceX, Starship’s Super Heavy booster, which is nearly 400 feet tall, smoothly returned to Earth and hovered above the Gulf of America for a few seconds before it went for its soft water landing. The booster’s picture-perfect maneuver before splashing down all but capped a near-flawless mission for Starship, which is about to enter its V3 era with Flight 12.
The booster’s balance and stability were so perfect that some users on X joked that the whole thing looked AI-generated. Considering the size of Super Heavy, as well as the fact that the booster was returning from space, the hovering display all but showed that SpaceX is dead serious about keeping its dominant lead in the spaceflight sector.
Starship V2’s curtain call
As noted in a Space.com report, Flight Test 11 achieved every major goal SpaceX had set for the mission, including deploying Starlink mass simulators, relighting Raptor engines in space, and executing a stable reentry for both the Starship Upper Stage and the Super Heavy booster. The feat also marked the second time a Super Heavy booster has been reflown, a milestone in SpaceX’s quest to make the entire Starship system fully reusable.
Starship’s V2 vehicle will now give way to the upgraded Starship V3, which is designed for faster turnaround and higher payload capacity. The Starship program is expected to pursue even more aggressive targets in the coming months as well, with Elon Musk stating on social media platform X that SpaceX will attempt a tower catch for Starship Upper Stage as early as spring 2026.

After moving Tesla to Texas, Elon Musk is back in the Bay Area with Neuralink expansion
The news marks a noticeable step in Musk’s expanding presence in the Bay Area, despite the move of his biggest companies, Tesla and SpaceX, to Texas.

Recent reports have indicated that Elon Musk’s brain-implant startup, Neuralink, has leased a five-story, 144,000-square-foot building in South San Francisco. At the same time, Musk’s artificial intelligence startup xAI is reportedly also looking around for a Bay Area office.
The news marks a noticeable step in Musk’s expanding presence in the Bay Area, despite the move of his biggest companies, Tesla and SpaceX, to Texas.
Neuralink’s Bay Area expansion
As noted in a report from the San Francisco Business Times, the property that Neuralink has leased is located at 499 Forbes Boulevard, and it was built by Aralon Properties before it was leased to cancer test developer InterVenn Biosciences. The site, however, had remained vacant since 2023 after InterVenn canceled its 10-year lease.
xAI, Musk’s artificial intelligence startup, is reportedly scouting for an even larger Bay Area office as well, as noted in a report from the San Francisco Chronicle. Combined, the two ventures could secure nearly 400,000 square feet of local workspace, a move seen as a symbolic return of sorts for Musk-led innovation to Silicon Valley.
Neuralink’s momentum
Founded in 2016, Neuralink develops brain-computer interfaces intended to help paralyzed patients control digital devices through thought. The company received U.S. regulatory approval in 2023 to begin human trials, with its first patient, quadriplegic Noland Arbaugh, making headlines for his stunning ability to control a computer cursor and play games using only his mind. Since receiving his implant, Arbaugh has stated that he now browses the web, plays video games like Mario Kart, studies neuroscience, and operates his smart home without lifting a finger.
Nauralink is only just getting started, with Elon Musk noting on X that the company is busy preparing its next product, Blindsight, for human trials. As per Musk, Neuralink is “aiming to restore (limited) sight to the completely blind next year,” an aggressive target for a potentially life-changing device.

Tesla Cybercab tests seem to be ramping up again
Elon Musk has stated that he expects the company to achieve a run rate of 2 million Cybercabs annually.

Tesla seems to be ramping the tests of its autonomous two-seater, the Cybercab, once more. This was hinted at in recent drone footage from both the Fremont Factory and Gigafactory Texas.
The fresh sightings of the Cybercab in the Fremont Factory and Giga Texas have renewed conversations about the vehicle potentially being built with manual controls today.
Fresh Cybercab tests
As noted by longtime drone operator Joe Tegtmeyer on social media platform X, he recently spotted a Cybercab driving on Giga Texas’ South River Road to the West side. Interestingly enough, the longtime Giga Texas watcher noted that this was the first Cybercab that he had seen conducting road tests in a while.
Over in the Fremont Factory, another Cybercab was spotted driving around the facility’s testing area. Similar to the Cybercab in the Giga Texas sighting, the vehicle that was spotted in the Fremont Factory seemed to be manually driven, at least based on the way it was being steered. This behavior has incited speculations among Tesla watchers that current Cybercab test units have manual controls, unlike their production version, which would have no steering wheel or pedals.
Cybercab production preparation
The sightings of Cybercabs around the Fremont Factory and Giga Texas bode well for the vehicle’s development and impending production. It does, if any, complement reports that Tesla has been busy setting up production equipment for Giga Texas’ Cybercab production line. At the same time, drone footage around the Giga Texas complex has also revealed that Tesla is stockpiling some Cybercab castings, a likely sign that initial test production of the vehicle might soon begin.
The Cybercab is expected to be Tesla’s highest volume vehicle, with CEO Elon Musk stating that he expects the company to achieve a run rate of 2 million Cybercabs annually. He also mentioned that the Cybercab will be easy to produce thanks to its Unboxed manufacturing process, so much so that its production would resemble a high-speed consumer electronics line instead of an automotive assembly line.
