In a flash of dramatic irony, Andrew Wheeler, the Administrator of the US Environmental Protection Agency, praised the Trump administration’s Safer Affordable Fuel Efficient (SAFE) Vehicles rule, a rollback of fuel economy standards that would allow automakers to sell more polluting vehicles in the United States.
“Too many reporters fail to mention one very important point: the Obama era CAFÉ standards were not attainable by the auto industry. The truth is, the SAFE rule sets realistic standards, will reduce pollution, and save lives!” Wheeler posted.
Such statements, of course, attracted strong responses. In a call with reporters on Tuesday, California attorney general Xavier Becerra remarked that the EPA Administrator’s Twitter announcement was downright wrong. “(EPA administrator Andrew Wheeler) issued a tweet saying that this new rule would save lives, and reduce pollution, and that it would provide significant benefits to the American economy. In each case, he’s wrong,” Becerra said.
On Tuesday, the National Highway Traffic Safety Administration and the Environmental Protection Agency announced the SAFE standards that will take the place of the Obama-era Corporate Average Fuel Economy (CAFE) rules, which required about 5% annual improvements in fuel efficiency every year from carmakers.
Under the CAFE rules, the EPA noted that automakers would have been required to sell cars and light trucks with an average fuel efficiency of about 54 miles per gallon in 2026 model cars. With the current administration’s SAFE rules, vehicles could simply average about 40 miles per gallon by 2026 to meet the new standards.
In a way, Wheeler’s tweet boiled down to one point. The old CAFE standards were simply unrealistic, and America needs the new SAFE rules to make sure automakers and car buyers win out. Interestingly enough, the EPA official’s post came amidst an ongoing climate crisis and a literal pandemic that involves a virus attacking people’s capability to breathe.
Bad timing and taste aside, the EPA Administrator appears to have conveniently forgotten one particular American carmaker that has had absolutely no problem meeting the “unrealistic” standards of the Obama-era CAFE rules. This carmaker currently stands as the most valuable US-based automaker by market cap, and in recent quarters, it has even turned a profit, highlighting the argument that there is a substantial demand and a solid business model for zero-emissions vehicles.
This carmaker, of course, is Tesla. The company had been producing electric cars since 2008, and it has been mass-producing vehicles since 2012. With the Model 3, Tesla started breaking into the mainstream market, with some car buyers trading in otherwise more affordable vehicles to acquire the electric sedan. A crossover, the Model Y, has begun deliveries ahead of schedule, and if initial impressions from professional reviewers are any indication, there’s a good chance that the all-electric crossover will be a disruptor as well.
With the United States’ SAFE rules, automakers like Ford and GM will likely have less incentive to push electric cars. This may be detrimental to both companies, considering that leaked production plans from both GM and Ford have shown that the veteran automakers are still committed to the internal combustion engine despite their pro-EV rhetoric. This could be a costly move for GM and Ford, since territories outside the United States, such as Europe and China, have committed to electrification.
But amidst all these, there is a silver lining. If veteran automakers like Ford and GM will not step up to the plate and provide good electric cars to meet the demand from buyers, a new breed of EV companies will. Tesla has proven that a well-designed, feature-rich, all-electric car like the Model 3 can dominate their established internal combustion counterparts. There’s a good chance that vehicles like the Cybertruck, or perhaps Rivian’s R1T, could do the same for high-end F-150s and RAM trucks.
In a way, the adjustment of the United States’ emissions standards could prove to be an opportunity for electric car makers. Beyond the United States, after all, authorities are going all-in on electric cars. And for some territories such as Europe and China, there is no more turning back.

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.
