Tesla’s Battery Day is less than two weeks away, and as anticipation continues to build in the lead-up to the event, the electric car maker seems to be hard at work getting its pilot cell production line ready for its first visitors. Fortunately, it appears that Tesla’s “Roadrunner” facility is coming together pretty well, with work seemingly ramping as the Tesla community enters the final stretch to Battery Day. 

Tesla enthusiast and drone operator Gabeincal recently conducted a flyover of the Roadrunner facility, which is located close to the Fremont factory. A look at the site shows that work in the facility is ongoing, and the massive cube-like extension at the top of the Kato Road building is also taking form. Interestingly enough, the materials spotted around the building in earlier flyovers of the site have been reduced, suggesting that equipment and other related materials may have been moved inside the facility. 

Also notable was the extra floor that Tesla is adding onto the Kato Road building. Fondly dubbed by the Tesla community as the “Magic Cube,” the structure has seen notable progress in recent weeks. This time around, the drone operator was able to get pretty close to the structure as well, getting a rare glimpse of its high ceilings and expansive floor area. Tesla has so far not shared any information about the role that the “cube” plays in the Roadrunner line. 

Initial reports about the Roadrunner site were shared last year, when CNBC reported that the Kato Road facility was being used by Tesla as a “skunkworks lab” to design and produce battery cells and battery manufacturing equipment. The publication’s report did not specify which cells were being produced on the site, though speculations suggested that the site was involved in Tesla’s initiative to develop and release a million-mile battery.

Tesla’s fillings to the City of Fremont suggest that the Roadrunner facility will be housing 45 research and development employees and up to 425 manufacturing workers that are spread through several shifts from Monday to Friday. Seemingly in preparation of a ramp in its operations, Tesla has posted a number of battery cell manufacturing-related job listings for the site, including Cell Engineers, Production Process Engineers, and Controls Engineers, to name a few. 

While the Roadrunner facility’s battery cell output will likely be limited due to its size, the facility may be enough to support the company’s upcoming low-volume vehicles like the Plaid Model S and Plaid Model X, as well as the next-generation Roadster. All three vehicles are expected to be at the bleeding edge of the electric car maker’s tech, making them a perfect fit for the company’s first custom-designed battery cells.

The Tesla Model Y was the best-selling vehicle in three different states in the U.S. last year, according to new data that shows the all-electric crossover outsold every other car in a few places. However, Ford widely dominated the sales figures with its popular F-Series of pickups.

According to new vehicle registration data compiled by Edmunds and visualized by Visual Capitalist, the Ford F-Series, encompassing models like the F-150, F-250, F-350, and F-450, claimed the title of best-selling vehicle in 29 states.

This dominance underscores the pickup truck’s unbreakable appeal across much of the country, particularly in rural, Midwestern, Southern, and Western states, where towing capacity, durability, and utility for work or recreation remain top priorities.

The F-Series has held the crown as America’s overall best-selling vehicle for decades, a streak that continued strong into 2025 despite broader market shifts.

Yet, amid this truck-heavy reality, Tesla made a notable breakthrough. The Model Y emerged as the top-selling vehicle, not just the leading EV, but the outright best-seller in three key states: California, Nevada, and Washington.

These West Coast strongholds reflect regions with robust EV infrastructure, high environmental awareness, generous incentives, and tech-savvy populations. In California alone, nearly 50 percent of new vehicle registrations were electrified, far outpacing the national average of around 25 percent.

The Model Y’s success here highlights accelerating mainstream adoption of electric SUVs, which offer spacious interiors, impressive range, rapid acceleration, and low operating costs.

Elon Musk: Tesla Model Y is world’s best-selling car for 3rd year in a row

Elsewhere, Japanese crossovers filled many gaps: Toyota’s RAV4 and Honda’s CR-V topped charts in several urban and densely populated Northeastern and Midwestern states, where fuel efficiency, reliability, and family-friendly features win out over larger trucks.

While Ford’s broad reach shows traditional preferences persist, at least for now, Tesla’s Model Y victories in high-population, influential states signal a gradual but undeniable transition toward electrification. As charging networks expand and battery technology improves, more states could follow the West Coast’s lead in the coming years.

This 2025 map captures a pivotal moment: pickup trucks still rule the majority, but EVs are carving out meaningful territory where consumer priorities align with sustainability and innovation. The road ahead promises continued competition between legacy giants and electric disruptors.

SpaceX CEO Elon Musk shared a brief Starship V3 update in a post on social media platform X, stating the next launch attempt of the spacecraft could take place in about four weeks.

The comment was posted on Musk’s official account on social media platform X.

Musk’s update suggests that Starship Flight 12 could target a launch around early April, though the schedule will depend on several remaining milestones at SpaceX’s Starbase launch facility in Texas.

Among the key steps is testing and certification of the site’s new launch tower, launch mount, and tank farm systems. These upgrades will support the next generation of Starship vehicles.

Booster 19 is expected to roll to the launch site and be placed on the launch mount before returning to the production facility to receive its 33 Raptor engines. The booster would then return for a static fire test, which could mark the first time a Super Heavy booster equipped with Raptor V3 engines is fired on the pad.

Ship 39 is expected to undergo a similar preparation process. The vehicle will likely return to the production site to receive its six engines before heading to Massey’s test site for static fire testing.

Once both stages are prepared, the booster and ship will roll out to the launch site for the first full stack of a V3 Super Heavy and V3 Starship. A full wet dress rehearsal is expected to follow before any launch attempt.

Elon Musk has previously shared how SpaceX plans to eventually recover Starship’s upper stage using the launch tower’s robotic arms. Musk noted that the company will only attempt to catch the Starship spacecraft after two successful soft landings in the ocean. The approach is intended to reduce risk before attempting a recovery over land.

“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk wrote in a post on X.

Such a milestone would represent a major step toward the full reuse of the Starship system, which remains a central goal for SpaceX’s long-term launch strategy.

Tesla has opened its first public Tesla Semi Megacharger site in Los Angeles. The station reportedly offers up to 750 kW charging speeds and is open to Tesla Semi customers.

The development was highlighted in a post on social media platform X by the official Tesla Semi account.

Tesla Semi Megachargers

The Los Angeles site seems to be the first public Tesla Semi Megacharger that is not located at a Tesla factory. It is also the third Megacharger site currently visible on Tesla’s map.

The Megacharger system is designed specifically for the Tesla Semi and is capable of delivering extremely high charging speeds to support long-haul trucking operations. Infrastructure such as this will likely play a key role in making the Semi competitive with diesel-powered transport trucks.

Tesla’s progress with the Semi has also drawn attention in recent days after Elon Musk biographer Ashlee Vance shared photos from inside the Tesla Semi factory near Giga Nevada. The images suggested that preparations for higher production volumes may be underway, hinting that a broader ramp of the Tesla Semi’s production indeed be approaching.

New deployment strategies

Tesla has continued expanding its broader charging network through several new strategies aimed at accelerating infrastructure deployment. One of these initiatives is the Supercharger for Business program, which allows third parties to purchase Tesla Supercharger equipment and deploy charging stations while still integrating with Tesla’s network.

The program recently marked a milestone in Alpharetta, Georgia, where the city deployed four 325 kW city-branded Superchargers near the Alpharetta Department of Public Safety on Old Milton Parkway. The chargers support the city’s Tesla Model Y police vehicles while also remaining accessible to the public.

As per a report from EVwire, the project was designed not only to support fleet charging but also to generate economic returns that could offset the city’s investment. Tesla’s Supercharger for Business program has already attracted several participants, including businesses and charging providers such as Suncoast Charging, Pie Safe bakery in Idaho, Francis Energy in Oklahoma, and Wawa convenience stores.
