Tesla Roadster production car will exceed insane prototype ‘in every way:’ Chief of Design
Tesla Chief Designer Franz von Holzhausen recently made a rare appearance at owner-enthusiast Ryan McCaffrey’s Ride the Lightning podcast, where he provided several key insights into the electric car maker’s design process from the early days of the Model S to the upcoming next-generation Roadster.
While speaking about Tesla’s “halo” vehicle, von Holzhausen mentioned that the all-electric supercar has been in a process of evolution since it was unveiled. The designer added that these changes will make the production vehicle even more impressive than the already-insane prototype that came out of the Tesla Semi’s trailer nearly two years ago.
“It’s evolving deservedly so; it needs more time. It will be even better than what we’ve unveiled. In every way,” Franz said.
Considering the specs of the next-generation Tesla Roadster that were announced during its unveiling, Franz’s statements are very exciting. The initial specs of the next-gen Roadster, after all, are already bordering on insane, with its 0-60 mph time of 1.9 seconds, its top speed of over 250 mph, and its range of 620 miles per charge due to its 200 kWh battery.
These specs already place the next-gen Roadster head and shoulders above the competition, while putting the vehicle well into the performance of the auto industry’s most esteemed hypercars. Thus, it is quite difficult to wrap one’s head around the idea that the production version of the all-electric car will be a more extreme vehicle.
For Franz, the Roadster is ultimately a passion project. Describing the moment he drove out of the Tesla Semi’s trailer as a “One More Thing” surprise during the all-electric long-hauler’s unveiling event, Franz stated that the experience was memorable, partly due to how impressive the vehicle was.
“It’s an amazing machine. That car is like no other. I think it showcases the ability of what an electric vehicle can be… Being able to finally show people that — that was a cool moment,” he said.
Inasmuch as the idea of a more extreme next-generation Roadster might seem ludicrous (or is it Plaid?), Tesla actually has a reputation for doing the very same thing. The Model 3, for example, was initially announced to have a 0-60 mph time of “less than 6 seconds” during its unveiling event. Even the vehicle’s “slowest” trim, the Standard Range variant that’s available off-menu, has a 0-60 mph time of 5.6 seconds. That’s a hair faster than the BMW 730d M-Sport.
Franz’s recent comments echo those of CEO Elon Musk’s when he discussed the Roadster in his guest appearance at the Ride the Lightning podcast a few months ago. While speaking about the vehicle then, Musk stated that the next-gen Roadster will reach a level of performance that is almost unfair to gasoline or diesel-powered cars.
“We’re going to do things with the new Roadster that are kind of unfair to other cars. (It’s) crushingly good relative to the next best gasoline sports car,” Musk said.
Tesla CEO Elon Musk has stated that the next-generation Tesla Roadster will only see a production of about 10,000 units per year. That’s far above the output of niche all-electric hypercar makers such as Rimac, but it’s still very low compared to the annual production of the Model S, X, and Model 3. With this in mind, and with a $200,000 starting price that is on the same ballpark as a moderately-equipped Porsche Taycan Turbo S, there is a pretty good chance that Tesla’s “hardcore smackdown to gasoline-powered cars” will see great demand well into its release.

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.
