Tesla and Volkswagen: from fierce competitors to unlikely allies
Tesla and Volkswagen have established themselves as unlikely allies in the world of turning vehicles toward electrification. However, the two companies did not always see eye to eye, but the tides have certainly changed. Evidence of this comes just a day after Elon Musk took an unexpected stop in Western Germany to see Volkswagen Chairman Herbert Diess.
Years ago, Volkswagen and Tesla were sitting at opposite ends of the spectrum. One company was a well-established marvel of German automotive manufacturing, while the other was struggling to rally enough capital to keep its own production efforts moving forward.
However, 2020 has given the two companies and effective dose of the “Freaky Friday” treatment, where the former automaker is struggling to keep functioning EVs on the road. Meanwhile, the latter is surging forward the charge to electrification and maintains a healthy lead over other companies that are attempting to follow in their steps.
But from 2008 to 2015, Volkswagen was far from ever being considered a Tesla ally. The German automaker was violating the EPA’s Clean Air Act by knowingly placing cheat devices in their car’s emissions systems. The scandal, known as Dieselgate, set a semi-permanent mark in the minds of the environmentally-conscious.
Many swore never to consider repurchasing a Volkswagen vehicle, but the company has won some prominent figures in the EV community. Most notably, Elon Musk. But the relationship wasn’t always healthy.
Musk was critical of a conspiracy that a Volkswagen employee was criticizing Tesla through a fake name. According to numerous sources, Diess had the situation handled, but the drama between the two companies didn’t necessarily end there.
Dieselgate was still slightly in the head of Musk. The CEO mentioned that Tesla’s HEPA grade filter was needed while sitting in close traffic because toxic tailpipe emissions could affect the air quality of those who occupy vehicles that are around. “Good thing gas/diesel carmakers didn’t cheat on their emissions or we’d be in real trouble,” Musk joked, indirectly taking a jab at Volkswagen’s wrongdoing.
In close traffic, poisonous gas spewing from the car in front of you goes straight into your AC intake. Good thing gas/diesel carmakers didn’t cheat on their emissions or we’d be in real trouble 😅

However, Musk has recognized that Diess is an ally and is driving Volkswagen toward electrification. The Tesla CEO even said that Diess is “doing more than any big carmaker to go electric. For what it’s worth, he has my support.”
Musk and Diess then appeared on stage together at the Golden Steering Wheel Awards in Berlin last November, trading compliments and smiling from ear to ear with encouragement. The two had shown their business ventures had resulted in a healthy friendship, and Musk even announced that Tesla would be bringing a new facility to Berlin on the same evening.
In early September 2020, Musk flew to Germany to conduct business. His final stop on his quick tour of the country was to pay his friend Diess a brief visit, where Musk drove the ID.3 from Volkswagen and took a peek at the Model Y’s competition in the ID.4. With Giga Berlin moving along swiftly and Tesla intending to start manufacturing vehicles in July 2021, it would seem that Diess would want to keep a competitor at bay and not reveal his plans for an electric car. But he was more than willing to show Musk around. Why?
While company collaborations are rare in the automotive sector, a Tesla and Volkswagen one wouldn’t be a far-fetched idea. The two companies have executives that are more than willing to show their products to each other, and the two could also help each other in improving their businesses. Volkswagen has been building cars in Germany since 1937. Eighty-five years of market data could help Tesla make an enormous impact on the German market, and Volkswagen could undoubtedly share some hints if Tesla required them.
Meanwhile, Volkswagen has had a very public problem with its MEB infrastructure within the ID family of cars. Tesla, on the other hand, has established itself as the most prominent figure in terms of software and EV tech, and it could always lend a helping hand to Volkswagen, especially considering Musk is more than willing to help electrified fleets come to life. “Tesla is open to licensing software and supplying powertrains & batteries,” Musk said to Teslarati In July. “We’re just trying to accelerate sustainable energy, not crush competitors!
Whether the two companies decide to help, each other remains to be seen. But, the partnership will help both Tesla and Volkswagen out, and in the big picture, enable the acceleration to sustainable energy to occur faster.

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.
