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 launched the slightly larger Model Y L in China last year, and it became a hit in no time. The longer wheelbase, larger interior, and slightly more forgiving legroom area in the Model Y L became a sought-after possibility for U.S. buyers, who have been begging the company for a larger SUV.
Now, Tesla needs it more than ever, especially considering the Model X was discontinued alongside its Model S sibling earlier this year. It looks to be more likely than ever, and based on recent reports, it will fall in line with CEO Elon Musk’s prediction that it would arrive in the United States in late 2026.
Recent reports from Forbes and Not a Tesla App both have indicated Tesla plans to bring the Model Y L to the U.S. this year. The reports cite “credible sources,” and an analyst from AutoForecast Solutions named Sam Fiorani stated that the car would enter production later this year.
Fiorani said:
“China, Australia, and India are supplied by the factory in China, which will not supply vehicles to the U.S. Production of the Model Y L is expected to begin in the U.S. in September, which will lead to sales beginning before the end of 2026.”
Production would take place at Gigafactory Texas.
Additionally, a few Model Y L units have been spotted under wraps in the United States, giving more indication that Tesla plans to bring the vehicle to the U.S. When Tesla is close to launching a vehicle in the U.S., it is not uncommon to see these models with the exact car covers that you see below:

It makes sense, especially considering Musk hinted the Model Y L would make it to the U.S. in late 2026, but it was up in the air. The CEO said the advent of self-driving might not warrant a larger SUV coming to the U.S. market specifically.
The problem is, consumers do not want to hear that. They love Tesla’s tech, FSD, and other features, but they need more space for growing families. The Model X is gone, and the most anyone can fit in a Tesla right now is seven people in the seven-seat Model Y. That back row is truly only large enough to fit small children comfortably.
Tesla fans have requested a full-size SUV, and the company has made some hints that it could be in the plans.
The Model Y and Model Y L differ noticeably in size, with the Model Y L being a stretched, six-seat variant designed for great interior room. The Standard Model Y measures approximately 4,790mm in length, 1,982 mm in width with the mirrors folded, 1,624mm in height, and 2,890mm in wheel base.
In contrast, the Model Y L extends to be about 4,969–4,976mm long (roughly 179mm or 7 inches longer), stands 1,668mm tall (+44mm), and features a significantly longer 3,040 mm wheelbase (+150mm), while maintaining the same width.
This elongation primarily benefits rear passenger space and enables a 2+2+2 seating layout with captain’s chairs, though it slightly reduces maximum cargo capacity behind the rearmost seats and adds a bit of overall mass and turning radius. The result is a more spacious family hauler that still shares the core footprint and agile character of the original Model Y.
In a major development that will inevitably strengthen Tesla’s dominant position in the American EV market, Polestar has been effectively banned from selling new vehicles in the United States, starting with the 2027 model year.
The U.S. Department of Commerce denied Polestar authorization under the Connected Vehicle Rule, which prohibits vehicles containing certain connected technologies (Cellular, Wi-Fi, Bluetooth, etc.) linked to China or Russia due to national security risks, including potential data collection on American drivers.

Polestar, which is majority-owned by China’s Geely Holding, could not obtain the required exemption despite producing some models domestically.
Polestar confirmed it will sell off any remaining inventory of the Polestar 3 and Polestar 4 models, while continuing service and warranty support for existing customers. No new models or major refreshes will reach U.S. buyers, and the company is pivoting its growth strategy to Europe, where it already generates the vast majority of its sales.
The outcome removes a direct premium EV competitor that had positioned itself as a stylish, performance-oriented alternative to Tesla’s lineup. The Polestar 2 challenged the Model 3, while the Polestar 3 and 4 targeted segments overlapping with the Model Y and upcoming Tesla offerings. Polestar’s U.S. sales had already been sluggish amid intense competition and slower demand, representing just 6 percent of its global volume in the first quarter of 2026.
While Polestar was not on Tesla’s level in the U.S., it still places a dent in the evergrowing field of Tesla competitors in the country, where it has long dominated EV sales.
Tesla faces none of these hurdles. As a U.S.-founded and U.S.-headquartered company with major manufacturing in Fremont, Austin, and Nevada, Tesla’s vehicles are built with compliant domestic and allied supply chains. Its Full Self-Driving technology, over-the-air software updates, and vertically integrated ecosystem were developed entirely in-house without foreign ownership entanglements that trigger national security reviews, at least in the U.S.
Of course, it did face a similar threat in China a few years back:

The Connected Vehicle Rule, first advanced under the prior administration and upheld under the current one, is part of a broader U.S. effort to protect the domestic auto industry and critical technology from Chinese influence. High tariffs on Chinese-made EVs and related restrictions have already reshaped the market. Tesla benefits directly: it avoids these barriers while continuing to lead in U.S. EV sales volume, Supercharger network expansion, and energy storage integration.
By clearing Polestar from the new-vehicle playing field, the policy reduces competitive pressure in the premium and performance EV segments where Tesla has invested billions. American consumers seeking cutting-edge electric vehicles now have one fewer option tied to foreign adversaries — and one clearer path to the market leader that has driven the EV transition from the start.
For Tesla, this is more than regulatory relief. It is a strategic tailwind that reinforces its position as America’s premier EV innovator at a time when domestic manufacturing and technological independence matter most.
Tesla Cybercab stands to gain from new rules that the Trump Administration is aiming to enforce on autonomous vehicles. On Thursday, NHTSA, under the Trump Administration’s U.S. Department of Transportation, commenced rulemaking on the Federal Motor Vehicle Safety Standards (FMVSS).
This effort aims to eliminate the mandate for manual brake pedals in vehicles that are designed to be driven exclusively by automated driving systems. This would impact the Tesla Cybercab, which the company has stated would operate without a steering wheel or pedals.

The Trump Administration is looking to revise FMVSS No. 135, which requires standard braking systems on light-duty vehicles.
Currently, the regulation requires light-duty cars to use traditional manual braking systems that allow operators to slow the vehicle. With the advent of self-driving in the U.S., these regulations need updating, and these are the changes that could come to FMVSS No. 135:
- Removes requirements for hand- or foot-operated brake controls for vehicles designed never to be operated by a human. Existing rules still apply to AVs that retain manual controls.
- All subject vehicles must still meet the same stopping distance performance criteria via alternative testing procedures.
- While this update ensures AVs can physically stop when commanded, NHTSA is separately developing safety performance requirements for AVs in real-world driving scenarios.
- NHTSA will continue to use its broad defect enforcement authority to investigate unsafe ADS behavior and oversee recalls.
As autonomy becomes a greater part of passenger travel, these types of rule adjustments will be more than reasonable. It will give manufacturers the ability to self-certify their vehicles and avoid any red tape that could ultimately delay the deployment of these vehicles.
Administrators are also incredibly excited about the opportunity to play a role in the advancement of self-driving vehicles.
“We are at the cusp of the greatest technological revolution in vehicle technology since the innovation of the Model T,” NHTSA Administrator Jonathan Morrison said. “If we want America to lead the way, we have to reimagine our regulatory framework. That’s why under Secretary Sean Duffy’s AV Framework, NHTSA is tearing down pointless barriers to innovative designs while strengthening the fundamental safety requirements that matter and holding AV developers accountable for safe performance.”
The Cybercab entered mass production at Gigafactory Texas in April. Tesla ultimately plans to push the vehicle into its Robotaxi fleet, potentially when frameworks like these are established.
