Tesla’s carbon-wrapped motor to pave way for new Roadster improvements
Tesla CEO Elon Musk appears to have shared one of the key updates that would be rolled out to the next-generation Roadster, an all-electric supercar that’s expected to be the company’s undisputed halo car. In a series of posts on Twitter, Musk explained that some of the Model S Plaid’s key innovations could pave the way for unlocking even more power for the next-generation Roadster.
Musk’s updates came as a response to Tesla bull @ajtourville, who inquired if the carbon fiber sleeves of the Model S Plaid’s rotors are direct-wound or pressed-on. The Tesla CEO noted that with the Model S Plaid, “fiber is wound over rotor at high tension load.” He also noted that the “carbon sleeve must put (the) copper rotor in compression or it loosens at low temp due to differential thermal expansion.”
Main advantage of this is a much stronger EM field compared with a rotor that is held together by metal (usually high strength steel).
Other advantage is that rotor can go to higher RPM, as carbon sleeve (mostly) stops copper rotor from expanding due to radial acceleration.

Musk highlighted that Tesla’s carbon-coated motor has several key advantages, one of which is a stronger electromagnetic field compared to a rotor held together by metal such as high strength steel. The rotors can also go to a higher RPM, as the carbon sleeve mostly stops the copper from expanding due to radial acceleration. In a later tweet, Musk noted that these innovations had given Tesla some ideas for increasing the torque and maximum RPM of the next-generation Roadster.
This would make the all-electric supercar into something even more impressive than its prototype. When it was unveiled in late 2017, Elon Musk announced that the next-generation Roadster would have a wheel torque of 10,000 Nm, which is already very impressive in its own right. With a higher maximum RPM, the next-generation Roadster’s production could offer some monstrous amounts of power. Together with its SpaceX-infused tech and 620-mile range, the Roadster could truly stand above the Model S Plaid, effectively justifying its expected base price of $200,000.
The Plaid carbon-wrapped motor is arguably the most advanced motor on Earth outside of maybe a lab somewhere. We have to keep some secrets!
We have a few ideas for increasing torque & max rpm even further for new Roadster. Definitely fun & exciting engineering ahead!

The machines that enable the production of the Model S Plaid’s new electric motors were made possible by Tesla Automation. Interestingly enough, Tesla Grohmann Automation, which is located in Germany, has been undergoing a pretty extensive expansion, as indicated by reports from electric vehicle owners in the area. This expansion is expected to correspond to more activity in the facility, particularly as Gigafactory Berlin starts its local operations.
The next-generation Roadster is the spiritual successor of the car that started it all for Tesla. But while the original Roadster was based on the Lotus Elise, the new Roadster is built and designed from the ground up by the company. This paves the way for specs that would likely need to be seen to be believed, such as its 0-60 mph acceleration of 1.1 seconds with its SpaceX package.

Tesla Model 3 gets perfect 5-star Euro NCAP safety rating
Tesla prides itself on producing some of the safest vehicles on the road today.

Tesla prides itself on producing some of the safest vehicles on the road today. Based on recent findings from the Euro NCAP, the 2025 Model 3 sedan continues this tradition, with the vehicle earning a 5-star overall safety rating from the agency.
Standout Safety Features
As could be seen on the Euro NCAP’s official website, the 2025 Model 3 achieved an overall score of 90% for Adult Occupants, 93% for Child Occupants, 89% for Vulnerable Road Users, and 87% for Safety Assist. This rating, as per the Euro NCAP, applies to the Model 3 Rear Wheel Drive, Long Range Rear Wheel Drive, Long Range All Wheel Drive, and Performance All Wheel Drive.
The Euro NCAP highlighted a number of the Model 3’s safety features, such as its Active Hood, which automatically lifts during collisions to mitigate injury risks to vulnerable road users, and Automatic Emergency Braking System, which now detects motorcycles through an upgraded algorithm. The Euro NCAP also mentioned the Model 3’s feature that prevents initial door opening if someone is approaching the vehicle’s blind spot.
Standout Safety Features
In a post on its official Tesla Europe & Middle East account, Tesla noted that the company is also introducing new features that make the Model 3 even safer than it is today. These include functions like head-on collision avoidance and crossing traffic AEB, as well as Child Left Alone Detection, among other safety features.
“We also introduced new features to improve Safety Assist functionality even further – like head-on collision avoidance & crossing traffic AEB – to detect & respond to potential hazards faster, helping avoid accidents in the first place.
“Lastly, we released Child Left Alone Detection – if an unattended child is detected, the vehicle will turn on HVAC & alert caregivers via phone app & the vehicle itself (flashing lights/audible alert). Because we’re using novel in-cabin radar sensing, your Tesla is able to distinguish between adult vs child – reduced annoyance to adults, yet critical safety feature for kids,” Tesla wrote in its post on X.
Below is the Euro NCAP’s safety report on the 2025 Tesla Model 3 sedan.

USDOT Secretary visits Tesla Giga Texas, hints at national autonomous vehicle standards
The Transportation Secretary also toured the factory’s production lines and spoke with CEO Elon Musk.

United States Department of Transportation (USDOT) Secretary Sean Duffy recently visited Tesla’s Gigafactory Texas complex, where he toured the factory’s production lines and spoke with CEO Elon Musk. In a video posted following his Giga Texas visit, Duffy noted that he believes there should be a national standard for autonomous vehicles in the United States.
Duffy’s Giga Texas Visit
As could be seen in videos of his Giga Texas visit, the Transportation Secretary seemed to appreciate the work Tesla has been doing to put the United States in the forefront of innovation. “Tesla is one of the many companies helping our country reach new heights. USDOT will be right there all the way to make sure Americans stay safe,” Duffy wrote in a post on X.
He also praised Tesla for its autonomous vehicle program, highlighting that “We need American companies to keep innovating so we can outcompete the rest of the world.”
National Standard
While speaking with Tesla CEO Elon Musk, the Transportation Secretary stated that other autonomous ride-hailing companies have been lobbying for a national standard for self-driving cars. Musk shared the sentiment, stating that “It’d be wonderful for the United States to have a national set of rules for autonomous driving as opposed to 50 independent sets of rules on a state-by-state rules basis.”
Duffy agreed with the CEO’s point, stating that, “You can’t have 50 different rules for 50 different states. You need one standard.” He also noted that the Transportation Department has asked autonomous vehicle companies to submit data. By doing so, the USDOT could develop a standard for the entire United States, allowing self-driving cars to operate in a manner that is natural and safe.

Tesla posts Optimus’ most impressive video demonstration yet
The humanoid robot was able to complete all the tasks through a single neural network.

When Elon Musk spoke with CNBC’s David Faber in an interview at Giga Texas, he reiterated the idea that Optimus will be one of Tesla’s biggest products. Seemingly to highlight the CEO’s point, the official Tesla Optimus account on social media platform X shared what could very well be the most impressive demonstration of the humanoid robot’s capabilities to date.
Optimus’ Newest Demonstration
In its recent video demonstration, the Tesla Optimus team featured the humanoid robot performing a variety of tasks. These include household chores such as throwing the trash, using a broom and a vacuum cleaner, tearing a paper towel, stirring a pot of food, opening a cabinet, and closing a curtain, among others. The video also featured Optimus picking up a Model X fore link and placing it on a dolly.
What was most notable in the Tesla Optimus team’s demonstration was the fact that the humanoid robot was able to complete all the tasks through a single neural network. The robot’s actions were also learned directly from Optimus being fed data from first-person videos of humans performing similar tasks. This system should pave the way for Optimus to learn and refine new skills quickly and reliably.
Tesla VP for Optimus Shares Insight
In a follow-up post on X, Tesla Vice President of Optimus (Tesla Bot) Milan Kovac stated that one of the team’s goals is to have Optimus learn straight from internet videos of humans performing tasks, including footage captured in third person or by random cameras.
“We recently had a significant breakthrough along that journey, and can now transfer a big chunk of the learning directly from human videos to the bots (1st person views for now). This allows us to bootstrap new tasks much faster compared to teleoperated bot data alone (heavier operationally).
“Many new skills are emerging through this process, are called for via natural language (voice/text), and are run by a single neural network on the bot (multi-tasking). Next: expand to 3rd person video transfer (aka random internet), and push reliability via self-play (RL) in the real-, and/or synthetic- (sim / world models) world,” Kovac wrote in his post on X.
