CEO Elon Musk says that SpaceX is about to begin the construction of “a much larger high bay” adjacent to the existing structure, an 82m (~270 ft) tall building used to complete assembly of Starship and Super Heavy boosters.

According to Musk, the newest addition to SpaceX’s arsenal of Starship production facilities will be located “just north” of an existing high bay, which measures approximately 30m by 25m (100′ x 80′). Most importantly, Boca Chica’s high bay is tall enough for SpaceX to use a bridge crane to stack 50m (165′) Starships and ~70m (~230′) Super Heavy boosters – far more efficient and protected than using wheeled or tracked cranes to assemble rockets out in the open.

Construction of the existing high bay began in May 2020 and was more or less complete by the start of 2021. The structure was truly finished in April 2021 with the installation of a heavy-duty bridge crane, though work continues to this day on what CEO Elon Musk has described as a bar and viewing area to be located at the top of the bay.

Musk’s assertion that the new facility will be “much larger” can be interpreted a number of ways. There’s a distant possibility that SpaceX will build a true NASA-style Vehicle Assembly Building like the colossal VAB used to fully assembled Saturn V and the Space Shuttle at Kennedy Space Center. For Starship, that would require a structure at least ~130m (~430 ft) tall – more than 50% taller than the current ‘high bay’.

More likely, Musk means that SpaceX will effectively be building a second similarly tall high bay but with far more usable floor space. The existing structure is large enough to fit four or far different Starship or Super Heavy ‘stacks’ at once, though SpaceX’s current setup appears to allow two or three vehicle sections to be stacked and worked on simultaneously. In his July 25th tweet, Musk implicitly noted that SpaceX does have a significant amount of mostly unused space that could be perfect for another assembly building directly north of the high and mid bays.

Generally speaking, SpaceX has a plot of land around 170m (~560′) by 190m (~620′) that’s currently half-used as a Starship scrapyard and overflow lot, but most of the space is empty. Even if SpaceX only turned half of that land into a sort of vertical Starship assembly line, it would still boost high bay floor space by at least a factor of five or six – and possibly 8-10x. With that much extra space enclosed in a permanent structure, it’s likely that this new facility could mark a new evolution in SpaceX’s ever-changing Starship factory.

Update: Elon Musk says that SpaceX’s second Starship ‘high bay’ will be “a little taller” than the first but have a “much bigger base” and multiple “gantry” (bridge?) cranes that will run the full length of the building.

Tesla just told us twice that Model Y L is coming to the U.S.

Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.

The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.

The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.

With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.

However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.

Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.

Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.

Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.

Tesla is using vehicle microphones to improve build quality: here’s how

Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.

It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.

As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.

The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.

It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.

Tesla’s ‘megacasts’ are key to massive build quality improvements

While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.

This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.

Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.

Tesla crushes Wall Street expectations, beats delivery estimates by over 15 percent

Published

on

Tesla (NASDAQ: TSLA) beat Wall Street expectations of 406,000 vehicles delivered in Q2 by reporting 480,126 deliveries for the three months ending in June.

Tesla reported it delivered 467,762  Model 3 and Model Y units, while 12,364 Model S, Model X, and Cybertrucks switched hands during the quarter. The Model S and Model X were officially sunset this past quarter and will no longer be part of the company’s Production & Delivery reports moving forward.

The quarter is a pleasant surprise and a good rebound from Q1, when Tesla slightly missed the Wall Street consensus of 365,645 cars by reporting 358,023 deliveries for the first three motnhs of the year.

Energy storage deployments also provided some strength in Tesla’s delivery report, hitting 13.5 GWh for Q2. This is a particular division of Tesla’s business that has been overwhelmingly robust over the past few years, truly being a strong point of the company’s overall model.

For the year, Tesla analysts still predict deliveries to trend in the 1.69 million unit region, a modest 3 to 5 percent increase from the 1.64 million cars the company delivered last year. Tesla will likely return to more sequential and noticeable year-over-year growth as the Cybercab project starts to ramp up considerably in the next few years.

Tesla has some other potential catalysts to spur vehicle deliveries, too. Not only is it expecting Cybercab to truly start making a change in the next few years, but other vehicles could be entering the company’s lineup.

The slightly longer Model Y L has been a highly speculated release candidate in the U.S. It has already done incredibly well in China, and U.S. buyers have been wanting slightly more interior space than the Model Y. Now that the Model X is gone, it is more needed than ever.

Q2 highlights a pretty stable automotive division within Tesla, and no true concerns arise from these figures, especially considering it managed to beat expectations convincingly.
