Tesla Model S “Refresh” spied track testing
New photos from the Tesla Fremont Factory obtained by Teslarati show the new Refreshed Tesla Model S and its new features, confirming the long-time speculation of whether the company’s flagship sedan would be updated nine years after its initial release. After the Plaid Model S was announced in 2019, slight cosmetic modifications were added to the car to increase aerodynamic performance in a track setting. Some of these new features included a wider body, a rear diffuser, and a spoiler. Tesla has made several changes to the Refreshed Model S, as seen in the photos below. The vehicle was spotted at both the Fremont Test Track and on public roads when the photographs were taken.
For those who are unfamiliar, Tesla operates its own test track behind the Fremont factory for its vehicles. In 2013, three years after Tesla’s purchase of the Fremont factory from GM, the electric automaker bought the 35-acre property that included the test track from the Union Pacific Railroad. It is located adjacent to the Fremont factory, so Tesla can take cars that need to be tested to the track within a few minutes. In the past, Tesla has tested vehicles like the Model Y and the 2020 Roadster at the track prior to their release, indicating that the new Model S that was spotted could be on its way to the company’s Design Studio shortly.
Initial rumors of the Model S refresh emerged in late 2020 after several updates to the Model 3 and Model Y vehicles. While the Model Y underwent several minor updates, like a new center console, new door paneling, and a heated steering wheel in China, the Model 3 was the subject of more noticeable cosmetic revisions. The mass-market sedan from Tesla was equipped with a full chrome delete kit that now comes standard, a new center console design, new headlights, double-paned glass, a powered trunk, and other interior revisions.
On the other hand, the Model S has only undergone one true cosmetic revision since its initial release nearly nine years ago: the removal of the nosecone. Since the vehicle has gone so many years without a real update or any major changes to its aesthetic qualities, Tesla may have decided it was time to “refresh” the car.
Now, photographs of the new Model S have been captured, showing a wider body, revised fog lights, new wheels, and several other cosmetic revisions.
A few of the more notable changes are a new front diffuser, a part that became standard with the newly-designed Plaid Model S. A diffuser displaces air underneath the vehicle’s body, increasing aerodynamic performance and making the flow of air more efficient during travel. Additionally, the front fascia has also been revised slightly. This is the second revision Tesla has made to this portion of the Model S since its release. The new design includes a larger central air intake vent for improved airflow and ventilation to the battery pack. This eliminates the possibility of overheating and improves battery lifetime and performance.

One of the more interesting and speculative details of the new Model S is that there is no touchscreen protruding from the top of the dash. The Model 3 and Model Y center dash screen can be seen from the outside of the vehicle when looking through the windshield. There is no evidence that Tesla is adopting the 3 and Y center touchscreen design for the Model S refresh. We are currently not aware of any modifications to the vertical touchscreen that has been standard on the Model S and Model X.
The fog lights located on the bottom of the front lip have also been modified, bringing a slightly new look to the lower lights. Additionally, new wheels appear to be on the Model S, and they look to be a revised version of the Arachnid wheels that Tesla included as a Referral Program reward back in 2016. Neither the 19″ Tempest Wheels nor the 21″ Sonic Carbon Twin Turbine Wheels that are available with the Plaid Model S matches the wheels that were equipped on the vehicle that was spotted at the Fremont Factory. This appears to confirm Tesla may also be releasing a new wheel design that will be included with the Refreshed Model S design.
It seems the refreshed Model S has adopted more features that are going to be included on the Plaid Model S, due to be released in late 2021. A wider fender design is paired with new, wider wheels. These modifications were first noticed on the Plaid Model S that was spotted running spirited laps at the Nürburgring in Germany in 2019.

Another interesting note is the side repeater cameras have been adjusted onto the new fenders, but only slightly. It appears Tesla has moved it forward toward the wheel well. This could be to increase visibility when the cameras are activated.
The final noticeable external revision is a new rear bumper design that is more robust than the original Model S design. This could be indicative that the black Model S in the photos we shared could be the Plaid Model S, as it also has a wider rear bumper. However, it does not have a rear diffuser installed underneath, meaning it could just be a refreshed design.

Tesla is holding its Q4 2020 Earnings Call on Wednesday and many enthusiasts believe the company will announce either a refresh to the Model S, or will indicate the Plaid Model S will be on its way soon. With the several external modifications that have been spotted thanks to the pictures above, we know that Tesla is working on a revised design for its flagship sedan. While no details are known about the interior as of yet, details will be shared as they are found.
The Kilowatts spotted some more photos of the unique Model S at Fremont, providing some additional perspective on what changes Tesla made to its flagship sedan.

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.
