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.

Tesla all but confirms that affordable Model Y is coming Tuesday
It does appear that October 7 would be the date when the world sees Tesla’s actual idea of what an affordable vehicle would be like.

Tesla has released a cryptic teaser of a product that would be announced on Tuesday, October 7, 2025. Based on the company’s hint, it does appear that the product would be the affordable Model Y that has been spotted doing road tests across the country over the past months.
Affordable Model Y sightings
Last week, news emerged that a number of key Tesla influencers visited Gigafactory Texas for a private event. These included veteran Tesla YouTubers, car reviewers, influencers on X, and even a teardown expert who provided the initial insights on how to improve the original Model 3 sedan. At the same time, an uncovered unit of the apparent affordable Model Y was posted online. The vehicle was reportedly sighted close to Giga Texas.
The new Model Y variant had some notable changes from the standard Model Y. Its fascia seemed inspired by the Model 3 sedan instead of the Cybertruck, and its roof seemed blacked out. Overall, it looked like a simpler Model Y designed to be offered at an affordable price.
The weekend teasers
Teasers about an upcoming product were posted by Tesla’s official account on social media platform X, though the electric vehicle maker made it a point to keep things very vague. Initially, a closeup video of what appeared to be an aero wheel was posted, though it was vague enough that some speculated that it could be Elon Musk’s long-announced HVAC system instead.
On Sunday, another teaser video was posted featuring the headlights of a new car. This brought speculations that the new Roadster might finally be announced. Inasmuch as a new Roadster unveiling would be exciting, however, it was evident that the headlights in the new teaser were a match to the uncovered affordable Model Y unit that was spotted close to Giga Texas a few days ago. With this in mind, it does appear that October 7 would be the date when the world sees Tesla’s actual idea of what an affordable vehicle would be like.

Tesla releases cryptic teaser for something massive and it’s coming this week
On Sunday morning, Tesla released a nine-second teaser video of what appears to be either a vehicle wheel, fan, or some sort of propeller, but there are no real clues as to what it could be exactly.

Tesla has released a cryptic teaser for something massive, and it will release details on it this week. With many different projects in the works, there is a lot of speculation going on about what it could potentially be, but we have a few ideas.
On Sunday morning, Tesla released a nine-second teaser video of what appears to be either a vehicle wheel, fan, or some sort of propeller, but there are no real clues as to what it could be exactly.
It then ends with “10/7,” meaning it will announce something on October 7, which is this Tuesday:

Given that Tesla has been working on a handful of pretty notable projects that are set for unveiling at the end of this year, and there are some clues that seem to point in their direction with this short teaser video.
There are two projects that come to mind almost immediately: the Tesla Roadster is one, and the “E41” or affordable model is the other. Here’s what we know about both:
Tesla Roadster Demo Event
Tesla said earlier this year that it would have a demo event for the Roadster to unveil some new technologies and show off what it has been working on over the past few years.
There have been a lot of crazy things in the works for the Roadster, including a SpaceX package that would use cold-gas thrusters for an insane 1.1-second 0-60 MPH acceleration rate. This package was also supposed to help it hover, something CEO Elon Musk has teased for the past few years.
The Roadster was ready for release earlier this year, but after Chief Designer Franz von Holzhausen and VP of Powertrain Lars Moravy showed Musk what they had come up with, he wanted more.
Moravy said on the Ride the Lightning podcast earlier this year:
“What we had come up with exceeded what we originally planned. So, Elon was like, ‘Wow, great. Let’s do more!'”
The Roadster event was coined as “the most epic demo,” and since it was planned for the end of 2025, it is totally feasible to believe this could be it.
Tesla ‘E41’ Affordable Model
Some believe the teaser could be the official launch of Tesla’s affordable model, which Musk said earlier this year is simply a stripped down Model Y.
There have been some sightings of this vehicle in the past few weeks, including one on Friday that showed the vehicle completely uncovered for the first time:
🚨 It looks like the new affordable Tesla Model Y was spotted near Giga Texas

— TESLARATI (@Teslarati) October 3, 2025
The launch of the affordable model makes sense, especially from a timing perspective. With the $7,500 EV tax credit officially coming to a close on September 30, many are wondering how Tesla will spark growth in its deliveries. A more affordable EV would be the perfect response, and it is something that Tesla has been working on for some time.
Other Potential Ideas
There are some pretty interesting ideas as to what the teaser could be apart from the Roadster or affordable model. Some believe it could be a cooling fan for a GPU cluster, which would make sense considering Tesla’s prowess in data.
Grok also made an interesting guess, stating it could be a propeller for a secret air taxi Tesla is developing. This seems sort of our of left field.
We do know Tesla hosted a handful of influencers at Gigafactory Texas this past week, so whatever the company showed them is likely what will be unveiled on Tuesday.

Tesla Optimus is learning martial arts in new video teasing capabilities
For the past few months, Tesla has been refining its capabilities and making some serious progress on what Optimus is capable of. This morning, Musk released a new video showing Optimus learning Kung Fu, perhaps its most impressive feat yet.

Tesla Optimus is learning martial arts, a new video released by CEO Elon Musk shows, a crazy development and advancement in the robotics project the company has been working on for a few years.
Optimus has been a major focus of Tesla for the past several years, especially as Musk has said he believes it will be the biggest product of all time and could be the biggest contributor to the company’s valuation.
For the past few months, Tesla has been refining its capabilities and making some serious progress on what Optimus is capable of. This morning, Musk released a new video showing Optimus learning Kung Fu, perhaps its most impressive feat yet:

The video shows Optimus working with a Kung Fu teacher, known as a Shifu, going through what appears to be some sort of routine of combinations. It’s quite impressive to see the fluidity of the movements and Optimus’s ability to keep up with Shifu.
Tesla has been “working hard” to scale Optimus production, Musk said last week, a project that has obviously confronted both AI and manufacturing teams with a variety of challenges.
The plan is to have an annual production run-rate of one million units by 2030, and there were plans to build 5,000 units this year.
Musk still believes Optimus will make up roughly 80 percent of Tesla’s value. In January, he said it would be “overwhelmingly the value of the company.”
Tesla plans to launch the Gen 3 version of Optimus soon, and although a video of a new-look prototype was released by Marc Benioff, the CEO of Salesforce, the company’s frontman stated that this was not what the next-generation prototype would look like.
Elon Musk confirms Tesla has never shown Optimus V3 design yet
This video seems to show there is still significant progress being made on the Optimus project, and it will be perhaps one of the most impressive humanoid robots available to consumers in the coming years.
