Tesla-owning Officer convinces Sheriff’s Office a Model Y would be perfect fit
Sergeant Clay Leak of the Boulder, Colorado Sheriff’s Office has several Teslas in his garage, but one at his job would have been a cherry on top. After a few months of diligence, Sgt. Leak has a Model Y in his Boulder Sheriff’s Office fleet, making it the latest force to introduce all-electric power into its law enforcement efforts.
It was a long process, Leak told Teslarati in an interview earlier this month. It took a lot of work, and it took a lot of phone calls, but eventually, things worked out as they should have. “I did a bunch of research by reading a bunch of articles, then reaching out to talk to agencies that I could get ahold of who had Teslas in their fleet,” Leak told us. He started with the Fremont, Westport, Bargersville, and Hastings-on-Hudson Departments, all of which have welcomed Tesla vehicles into their fleets. Fremont has a Model S, Westport and Bargersville a Model 3, and Hastings-on-Hudson would operate that same model as Boulder: a Model Y Long Range.

The process then seemed to make sense as the financial figures lined up nicely for a presentation to local commissioners who would ultimately have the final say. “I talked to our in-house fleet manager and pulled the mileage, fueling, maintenance, and service records for our fleet,” Leak said. He did not think it would be a very difficult convincing process as cutting costs of fueling and maintenance swayed in the direction of the Model Y. After calculating Wh/mi for the Tesla and comparing it to the cost of operating a gas-powered Ford Police Interceptor, it was no match. The Model Y was around five times as cost-effective than the typical Police Cruiser. Plus, the sustainability factor was another big positive in the way of purchasing the Model Y.
“Boulder County has always strived to be eco-friendly in all our operations, and we continue that commitment by being one of the first, if not the first law enforcement agency in the State of Colorado to bring a Tesla Model Y into our patrol fleet,” the department wrote.
Within six months, the Model Y could already begin saving the Department money, according to a Media Release the department published earlier this week. After the Command Officers agreed with Leak’s calculations and ideas for a sustainable member of the fleet to be added, it went to Boulder County Commissioners, who ultimately approved the project and authorized the purchase.
“I think taxpayers will be happy to hear that this new vehicle will save money,” Leak said. “It will take time, but it will be less expensive than the gas-powered vehicles we have now.”
Then came the fun part, installing the necessary police equipment on the inside of the car, and outfitting the Model Y with decals. “We worked with Tesla, because there were some things that just didn’t line up,” Leak stated. He detailed how the programs the Boulder Sheriff’s Office uses are Windows-based, while the Model Y’s center dash screen is HTML-based. This made it necessary to install a patrol laptop, which is in normal cruisers as well.
The Department said in its release:
“The vehicle has been outfitted with official Boulder County Sheriff’s Office decals as well as a full suite of emergency equipment like that used in many of our other vehicles. It will primarily be assigned for traffic enforcement, though it will be rigorously tested to examine its potential for other applications within the Sheriff’s Office. Our research included examining EV offerings from other manufacturers, but they were ultimately eliminated from consideration due to significantly higher price points, lack of availability, and/or specifications that did not meet our needs. We are open to reconsidering them in the future as the EV market expands.”

The Department expects the vehicle to make it 200,000 miles at minimum. However, Leak is looking to increase the sustainability of the Model Y Cruiser by offsetting electricity costs with solar panels.

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.
