SpaceX begins assembling Starbase’s biggest manufacturing building yet
It might not look like much today but SpaceX has begun assembling what is set to become Starbase’s largest Starship manufacturing facility.
The structure, which has generally come to be known as Starbase’s ‘wide bay,’ was first teased by CEO Elon Musk in July 2021 and will be the fourth permanent assembly ‘bay’ constructed at Starbase – currently SpaceX’s sole dedicated Starship factory. The first, now known simply as the windbreak, is a triangular bay built in 2019 that is mostly unused but occasionally supports work on Starship nose assembly. Next, SpaceX built a larger ‘mid bay’ in the first quarter of 2020, out of which every Starship prototype and test tank since SN3 has been built.
A few months after the midbay was finished, SpaceX began constructing an even larger ‘high bay’ around 81 meters (265 ft) tall and 30 by 25 meters (100 by 80 ft) wide – about twice as tall and with twice the area, in other words. While the midbay was specifically optimized for assembling one or two Starship tank sections at a time, the high bay was designed to be large enough to fully assemble one Super Heavy booster (69m/225ft tall) and stack a Starship tank and nose section (50m/165ft tall) at the same time. The goal of SpaceX’s new ‘wide bay’ may be even loftier still.
Though SpaceX’s pace of Starship and Super Heavy assembly and processing appears to have slowed down significantly in the last few months, the company has still proven with Starships SN4-6, SN8-SN11, and SN15-16 that it can build large numbers of suborbital prototypes at the frankly incredible pace of 1-2 per month. With Super Heavy BN1, BN3, and BN3, SpaceX – to a lesser degree – has also demonstrated respectable booster prototype production, though none have flown and only one has completed any testing.
Nonetheless, as SpaceX works to complete Starship S21 and Super Heavy B5 and prepares to begin assembling S22 and B6 while Ship 20 and Booster 4 still sit – largely untested – at the launch site, Starbase’s existing production capabilities are already starting to outstretch its two main assembly bays. In other words, the purpose of SpaceX’s new ‘wide bay’ is almost certainly to double, triple, or even quadruple Starbase’s maximum vehicle production rate.
The wide bay’s dimensions have yet to be officially confirmed but based on aerial views of its foundation, it will measure roughly 50m (~165′) wide, 35m (~115′) deep, and 90-100m (~300-330′) tall, giving it more than twice as much usable floor space as the high bay. In theory, the high bay has enough space for SpaceX to stack 3-4 four Starship or Super Heavy tank sections at once. With more than twice the floor space, the wide bay should singlehandedly allow SpaceX to assemble 3-4 Super Heavy boosters, 4-8 Starships, or 2-3 boosters and 2-3 Starships at once.
At the absolute minimum, once fully outfitted, that means it could roughly triple the number of boosters or ships Starbase can fully assemble each month. Pictured below, there’s also a small but not insignificant amount of evidence (the small rectangles left of the wide bay foundation, bottom right, in the photo above) that SpaceX is completing additional foundation work that could double the wide bay’s floor space yet again. The second 50x35m structure those foundations seem to outline could be a wider midbay, a few-story ring assembly floor to augment Starbase’s tents, a 50x70m ‘high bay,’ or simply a more permanent space for general offices, workshops, storage, and other miscellaneous uses.
Stay tuned for updates on the massive structure’s construction.
Tesla has updated its Robotaxi app so riders can pick which vehicle they want before they book. The latest in-app screens now show two options side by side: the two-seat Cybercab and the four-seat Model Y.
A screenshot circulating Thursday shows the change in practice. In Austin, a rider could choose a gold Cybercab for two people or a Model Y for four. Tesla’s updated description calls Cybercab “our first purpose-built autonomous vehicle,” designed for safety, accessibility, and comfort, and says the lineup is available only through the Robotaxi app.
Tesla has updated their Robotaxi page in the App Store. You’ll be able to select if you want a Cybercab or Model Y Robotaxi.

The distinction is more than cosmetic, and it’s important to note that Robotaxi refers to the platform, while Cybercab refers to a vehicle.
Model Y Robotaxis have carried the service since it opened in Austin in mid-2025 and later expanded to Dallas, Houston, and parts of Florida. Those vehicles are converted production SUVs that still have steering wheels and pedals.
Cybercab is different. It has no driver controls, butterfly doors, a low seat height meant to work with wheelchairs, extra trunk space for assistive devices, and braille on the handles. Tesla has registered dozens of the two-seaters with Texas regulators in the days leading up to its September 3 Austin event.
Giving riders a choice lets Tesla match the vehicle to the trip. Most rides involve one or two people, which is where Cybercab is meant to be cheaper and more efficient to operate. Groups of three or four, or anyone who needs more space, can still request a Model Y.
The same app handles booking, payment, cabin settings, and, on Cybercab, features such as phone-based door opening and in-cabin voice controls.
The update does not mean every city suddenly has both cars available. Cybercab support is listed for Austin first, and the purpose-built fleet is still small compared with the existing Model Y roster. Even so, the app change marks a shift from a single-vehicle pilot to a mixed fleet.
Riders can now choose between the compact, purpose-built robotaxi and the familiar SUV that launched the service.
Tesla Cybercab sightings are broadening far and wide, well outside of downtown Austin, Texas, with autonomy in focus as the company plans to launch the all-electric, two-seater this evening in the Lone Star State.
Tesla is set to launch Cybercab to a small group of people this evening in a dedicated event in Austin, Texas. Public details on the event are relatively slim.
However, Tesla’s focus on Cybercab falls well outside of the downtown Austin area and is expanding well across the United States as things continue to move quickly with the company’s autonomous efforts in 2026. Today, various images of Cybercab fleets in interesting locations have started to circulate.
The most notable is a fleet of at least 20 Cybercabs at Miami International Airport in Florida. Spotted last night, the fleet is expansive and is indicative of a looming release of Cybercabs once regulatory boxes are checked off.
Tesla has already been operating the Robotaxi platform in Miami for several months, but this Cybercab fleet at the airport could be joining the ride-hailing platform as approvals arrive:

Another fleet of Cybercabs was spotted at the Devon, PA showroom just outside of Philadelphia. We have seen several Cybercab units testing around the Philadelphia Metro Area, which is interesting considering Tesla does not have any active Robotaxi geofence in Pennsylvania.

Philadelphia would be an ideal location to test ride-hailing due to its dense tourist population, large, sprawling city layout, and to compete with other ride-hailing companies that operate in the city.
Expansive fleets of Cybercabs will be popping up in and around major cities throughout the rest of the year, if we were betting on it. Tesla has made it obvious that the Cybercab rollout will be aggressive and fast-paced, but within reason. Tesla is still prioritizing safety, so these testing phases will likely go on for some period of time before more members of the public are able to snag a Cybercab for a personal chariot.
The Tesla Model Y L is arguably the most hyped trim of the all-electric crossover, other than the Performance configuration that comes with white-knuckle speed and sports car-level handling.
However, it is not all perfect. Tesla owners in China who took delivery of the Model Y L, denoted with an L to highlight its longer wheelbase, are experiencing what they are referring to as “collapsing” of the rear wheels, as suspension issues appear to be an issue with some of the builds.

• Owners say the rear tire-to-arch gap shrinks after mileage or a full load. Some cases after about 9,000 km loaded. Others near 30,000 km

The gap between the wheel arch and tire has narrowed to the point that “not even a single finger” could fit, according to a report from Car News China. The failures are not tied to a specific mileage, as one owner said that after just 9,000 kilometers (5,600 miles), they noticed the suspension issue when their car was fully loaded.
Another one had the issue at 30,000 kilometers (18,640 miles) and noticed that the wheel gap shrank to two fingers, so not as drastic as the person who reported a similar issue at 9,000 km.
Tesla Model Y L is gaining momentum in China’s premium segment
Along with the visual recognition of the issue, others are saying the sagging is causing abnormal wear on the inside of the tires. Extra weight and instant torque already provide additional stress on the tires in electric vehicles during normal operation, so it is no surprise that this is another complaint.
There has been no recall issued by Tesla, and the company has not yet publicly acknowledged the issue.
Some are suggesting that owners use a “finger test” to self-diagnose whether there is an issue with the suspension. There should be four fingers between the tire and the wheel well; anything less than that starts to get dicey.
