The Tesla Semi’s butterfly effect will change the face of heavy-duty freight routes
In a recent interview, Auke Hoekstra, a researcher at Eindhoven University of Technology and an electric vehicle expert, explained how battery-electric trucks like the Tesla Semi could end up dominating heavy-duty freight routes in regions like Europe. According to the EV expert, weight and range limitations that are usually associated with electric vehicles may very well be quite irrelevant when it comes to the real-world use of the electric long-haulers.
While addressing questions from Clean Energy Wire, Hoekstra explained that skeptics of vehicles like the Tesla Semi often take the hardest business case that a diesel truck is able to manage. An example of this is a multi-day trip with a team of two drivers who cover thousands of kilometers in one trip. The EV expert explained that while traditional diesels still hold an advantage against their battery-electric competition in this scenario, this edge disappears when one looks at the greater trucking market.
“My research in the Netherlands has revealed that 80% of trucks – even the really big rigs, the semis – travel 750 kilometers per day at the very most, and many cover far shorter distances. That’s because if you want to cover more kilometers, things become very expensive very quickly, because you have to pay overtime, etcetera. So, in general, you can’t make a driver do more than 750 kilometers per day. Therefore, this is the range you have to hit with about 80 percent of trucks.
“Additionally, almost all trucks return to base at the end of the day – which creates ideal conditions for charging. We still have this romantic idea that truckers are on the road for weeks on end, away from home. But this scenario has become relatively rare. Most truckers simply move stuff from Rotterdam port to Venlo, halfway to Germany’s Ruhr area, to take an example from home… Many truckers do this sort of trip a couple of times per day, and then return home. So, you can charge the vehicle overnight at a default location. This means you don’t have a chicken and egg problem – you can arrange for the infrastructure and for the truck at the same time,” the EV expert remarked.
Interestingly enough, Elon Musk has recently remarked that Tesla is looking to release the Semi with a range that falls well within Hoekstra’s numbers. While speaking at the European Battery Conference, Musk stated that he believes it is feasible to achieve 800 kilometers of range for the Semi quite easily, and he also sees a path, over time at least, for the Class 8 truck to achieve an even more impressive 1,000 kilometers per charge. Such numbers can go a long way towards shifting the market’s perception of all-electric long-haulers and their limitations. Hoekstra, for his part, noted that such a scenario has already happened before with the original Tesla Roadster.
“I do remember that in the car market, things really changed when the Roadster hit the market. That really changed the conversation. It changed the whole perception of electric vehicles. The conventional wisdom back then was that you can only use them on short distances in the city. And suddenly this car appeared, and everything was possible.
“Within the next couple of years, we’ll see the first Tesla semi-trucks on the road. This will have a similarly huge impact on the conversation about electric trucks. You can just point to it and say: “Look, it’s moving there, and it is doing 800 kilometers.” Suddenly, all those people who say ‘it cannot be done’ within truck companies will hear their boss replying: ‘Well, our competitor can do it – so you will have to do it, too.’” Hoekstra said.
What’s quite remarkable is that this is not even the most exciting part of the Semi’s butterfly effect on the trucking sector. If the Tesla Semi finds solid footing in the trucking market in the same way the Model 3 found a good niche among premium midsize sedan buyers, a “Tesla Effect” of sorts could happen on the trucking market. This could come in the form of other battery-electric trucks being developed for the long-haul market. This should, in turn, result in a massive innovation push from several truck makers, similar to what is happening now with companies like Tesla, Lucid, Rivian, and veterans like Ford and GM in the consumer EV segment.

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.
