Tesla Top 5 Week in Review: TSLA surge, 0-60 mph 2.05 sec, neural nets, and more
Tesla has been in the news a lot this week, as usual, but the biggest headlines surrounded its unexpectedly strong stock market performance. Another event that made the Tesla crowd happy was the release of a new over-the-air software update which removed a power limiting safety feature. In a related story, a team of creative folks reverse engineered the maximum theoretical acceleration of a car; if you didn’t read this story, you’ll be amazed what they found out. Tesla CEO Elon Musk was a featured speaker in the UAE at the World Summit, which coincided with Tesla’s entrance into that market. And Musk also offered some fascinating insights about artificial intelligence and what the future might look like if humans don’t stay current with AI’s potential. Here are those stories.
Tesla (TSLA) shares surge across 52-week high as Model 3 production takes stage
Over a six month period, Tesla shares rose by nearly 25% and traded this week above $280. This is within grasp of the company’s all-time high, with a market cap that has grown by $10 billion. Investors have begun to give more weight to Tesla’s highly anticipated Model 3, which is slated to begin production on February 20. Development and planned timeline launch for the Model 3 look good and are critical to Tesla’s continued success moving forward. If all goes as hoped, the vehicle will help take the company from producing about 100,000 cars annually today to 500,000 annually in 2018.
Tesla removes performance restrictions in latest software update
Tesla’s policy on limiting the power output of its performance vehicles due to frequency patterns of launch mode engagement and maximum power levels has ended. This week, the car manufacturer pushed a software update to its customers that removes power limiting on Performance variants of its Model S and Model X. Tesla continued to remind its customers that prudent habits can prevent premature wear of components due to high stress launches. Tesla confirmed that they will now “monitor the condition of the powertrain and display an alert if service is needed so we can take proactive steps, such as by replacing parts if necessary, to maintain the vehicle’s performance.”
Math says, Tesla’s “Maximum Plaid” mode could achieve 0-60 mph in 2.05 seconds
In this article scoop, Teslarati related how a group of really creative folks at Engineering Explained decided to reverse engineer the maximum theoretical acceleration that a Tesla Model S could achieve. The team worked somewhat counter-intuitively. They began by calculating the maximum deceleration first. Then they moved back up to acceleration, focusing on a stock Model S with stock tires. The result? Tesla’s next generation Roadster with “Maximum Plaid” mode may have the ability to accelerate from 0-60 mph in 2.05 seconds.
Elon Musk presents at the Tesla Launch Event in the UAE (Video)
Tesla CEO Elon Musk was a celebrity speaker at this week’s World Government Summit in Dubai. In his remarks, Musk noted, “We expect to invest tens of millions of dollars in the UAE for charging, service and support infrastructures. By next year, you’ll be able to travel anywhere in the GCC with an electric vehicle.” As he spoke about sustainability, Musk acknowledged that EV availability wouldn’t necessarily translate into immediate sales, as the region still considers fossil fuel-powered cars to be the preferred method of transportation. Following Musk’s visit, the UAE announced that it had ordered 200 Model S and Model X vehicles for use as a limousine service.
Elon Musk says human brains need to merge with AI to stay competitive with machines
As artificial intelligence technology improves, as some point humans will become irrelevant. That’s why we must learn to merge with machines, according to Tesla CEO Elon Musk, who explained some of his beliefs about the dangers of artificial intelligence this week. “I think we need to be very careful in how we adopt artificial intelligence and that we make sure that researchers don’t get carried away,” he stated. “Sometimes what will happen is a scientist will get so engrossed in their work that they don’t really realize the ramifications of what they’re doing.” Musk described how humans can mitigate those dangers through a type of merger of biological and machine intelligence, which he said would solve the problem of humans losing control over artificial intelligence.

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.
