Tesla Model Y’s revised suspension impresses car expert: ‘It was like riding on rails’
Automotive industry veteran Sandy Munro is in currently in the process of tearing down the Tesla Model Y. In a recently uploaded video, Munro delved into the vehicle’s suspension system, highlighting some of the subtle differences that Tesla made from the Model 3 to the Model Y.
Munro states that he is impressed with the new suspension of the Model Y. In an interview with Bloomberg Technology on YouTube, he says, “I thought this thing handled really well. I liked it; it was like riding on rails.”
In the recent MunroLive post, Munro highlights the similar suspension design between both the Model 3 and the Model Y, but clarifies that the two are not completely the same. One of the first differences Munro highlights is Tesla’s use of screws on the Model Y’s suspension dampers.
Previously on the Model 3, Tesla utilized a series of small bands to reinforce the sedan’s damper system. The primary function of this piece of the suspension is to quite literally “damper” the amount of bounce during travel. The damper controls the oscillation of the suspension spring and creates a less bumpy and smoother ride.
The reinforcement of the damper to the suspension system with screws creates a more robust and sturdy support. The Model 3’s damper system was subject to some complaints as per posts on the Tesla Motors Club forum, with some owners stating that their cars’ damper systems were weakening. Tesla could have reinforced the Model Y’s suspension system with screws because of the vehicle’s higher weight, as well.

Munro then commented on the “much beefier” build of the Model Y’s front suspension lower control arm, which is responsible for allowing suspension setting parts to rotate whenever the car is cornering. Tesla’s decision to create a more reliable control arm for the front suspension of the vehicle could also be due to the Model Y’s higher weight compared to the Model 3. But reasoning aside, Munro was happy with the decision to create a more robust control arm as it contributes to the Model Y’s improved suspension system.

In the rear suspension, there were fewer changes compared to the Model 3. The Model Y Performance that perched on top of Munro’s car lift was actually equipped with rear suspension lower control arms that were labeled as Model 3 parts. Munro states the commonality between the two parts not only suggests that Tesla had it right with the Model 3’s rear lower control arm, but that the carmaker will reduce spending money on developing or installing revised parts on its new vehicles. “This is a good idea for carmakers to use, or reuse, parts that have proven to be worthwhile,” Munro says.
The subtle changes Tesla decided to make the Model Y’s suspension system compared to the Model 3 not only increased cost-effectiveness but also improved the overall quality of the vehicle’s suspension. Munro states that a more in-depth analysis of the Model Y’s suspension will come when his team completely disassembles the car. According to this preliminary look at the system, Munro has noted drive quality and build quality improvements that have matched some of his standards so far.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
