SpaceX working on several Starship, Super Heavy upgrades and design changes

Published

Not long after Elon Musk confirmed plans to add three more Raptor engines to Starship and stretch the upper stage’s propellant tanks, the SpaceX CEO has confirmed one of several smaller design changes planned in the interim.

On January 3rd, Musk confirmed that SpaceX is entirely relocating one of two secondary ‘header’ tanks that Starships use to store landing propellant. A graphic sketched on the side of future Starship rings further revealed plans to tweak most of the subsections that SpaceX stacks to form a Starship, complementing an upgraded nosecone design. Finally, another design change was spotted on hardware that will eventually become part of the first full-thrust Super Heavy booster.

According to Musk, starting with Starship 24 (S24), which is likely the next ship SpaceX will complete, the methane (fuel) header tank will be relocated from Starship’s common dome to its nosecone. From the start, Starship’s oxygen header tank has been located in the very tip of the nose – placed in such an inconvenient location for the sole purpose of shifting Starship’s center of gravity forward. Now, the methane header tank will join it in the nose, with the obvious explanation being a need to shift that center of gravity even further forward. It’s possible that this change was planned before SpaceX realized the performance benefits of a stretched, nine-engine Starship, but it could also be a preemptive modification meant to counteract the added weight of three more Raptor engines and longer tanks.

Musk’s confirmation of the methane header tank’s relocation came just a few days after a drawing on the side of a Starship section further confirmed several more minor design changes. Starbase ‘hieroglyphics’ are not uncommon, as SpaceX engineers and technicians have often used hardware itself as a sort of whiteboard to sketch out plans and literally annotate ongoing work. This particular drawing was exceptionally detailed and useful, effectively showing exactly how Starship’s design will change beginning with Ship 24. The changes are simple enough: in essence, SpaceX will be adding an extra ring to several Starship ‘sections.’ For current ships, six distinct sections are stacked to form the Starship’s cylindrical tankage and hull.

It takes another five stacked sections to complete the current nosecone design. Counting the nose as one, it takes about seven stack operations to fully assemble the basic structure of a Starship. With the design changes sketched out on a Starship S24 ring and an upgraded nosecone that will debut on the same ship, fully assembling a nosecone will now take two or three stacks (down from five) and fully assembling a Starship will take six stacks (down from seven). While obviously not a major redesign, the changes will significantly simplify (and thus potentially speed up) Starship assembly, which will have additional positive follow-on impacts on plumbing, wiring, and heat shield installation.

There’s good reason to believe that some of the changes – especially expanding Starship’s nose barrel from four to five rings tall – will end up being applied to Super Heavy, potentially reducing the number of booster ‘sections’ needed from nine to seven or eight. However, there are already signs of some weirder changes being made to Super Heavy’s design. On December 21st, a Super Heavy thrust dome – likely Booster 7’s – was sleeved with several steel rings as part of a now-routine process, partially completing the first 33-engine thrust section. However, instead of the usual aft barrel section comprised of three six-foot-tall (~1.82m) steel rings, this ‘sleeve’ was made up of four ~1.4m-tall rings – the first time in Starbase history that shorter rings have appeared on any hardware.

This traditional three-ring Super Heavy thrust dome ‘sleeve’ design is present on Boosters 3, 4, and 5. (NASASpaceflight – bocachicagal)

Unlike all the other changes described above, it’s entirely unclear what benefit SpaceX is getting from keeping a given ship or booster section the same height while adding more smaller rings to it – a process that will inherently increase the complexity and amount of work required to complete that section. Regardless, it’s clear that SpaceX is in the midst of a significant period of design revision that could see Ship 24 and Booster 7 debut with a wide range of upgrades and design changes in just a few months.

Tesla has made a major production announcement at its Chinese production facility, Giga Shanghai. The change of plans comes right after the company announced its strongest quarter in terms of deliveries in its history.

On Monday, Tesla China Vice President Grace Tao announced that the production facility would begin ramping up manufacturing in preparation for an even stronger Q4.

Tao said on the Chinese social media platform Weibo:

“The Shanghai Gigafactory has recently begun its fourth-quarter production ramp-up! In the third quarter of 2025, Tesla delivered a total of 497,000 new vehicles worldwide, setting a new quarterly delivery record. As the fourth quarter begins, our colleagues at the Shanghai factory are working hard to expand production and fully charge their vehicles, so that car owners in China and Asia-Pacific can receive their vehicles as soon as possible.”

China is an extremely robust market for electric vehicles, and Tesla routinely delivers strong numbers in the sector.

However, Giga Shanghai is responsible for much more than just China, as it is a major export hub for other markets, including Asian-Pacific countries like New Zealand and Australia, among others.

Tesla delivered 497,099 vehicles in Q3, its strongest quarter ever from a delivery standpoint. About half of those vehicles came from Shanghai, as estimates point to roughly 242,000 of those cars coming from the Chinese factory.

Tesla China comeback: Retail sales hit second-highest month of 2025

Ramping up production at Giga Shanghai signals some internal belief that there is a lot of strength in terms of demand for Tesla vehicles. Tesla has a strong track record of fulfilling the need for its vehicles at the Shanghai factory, as it is widely regarded for building some of the best-quality Tesla vehicles.

However, the company launched a new configuration of the Model Y, called the Model Y L, in China. It is only available from Giga Shanghai and features a third row of seating and additional length in the wheelbase.

This additional space was widely sought out by customers, and Tesla listened. It could be a key to the company continuing its strength in the Chinese market, especially as there are many well-equipped competitors in the country.

Tesla China comeback: Retail sales hit second-highest month of 2025

Tesla’s September numbers are just below the 74,127 units that were sold domestically in March.

Tesla’s retail sales in China climbed to 71,525 vehicles in September, the company’s second-highest monthly total this year, as per data from the China Passenger Car Association (CPCA). 

The result reflects a steady rebound, narrowing Tesla’s year-on-year sales decline to just 0.93%, while showing a 25% jump from August’s weaker numbers. Tesla China’s September numbers are just below the 74,127 units that were sold domestically in March.

Tesla China’s September

Despite the uptick, Tesla China’s retail sales have now logged seven months of year-on-year declines this 2025, managing growth only in March and June, though a good portion of these lost sales was due to the changeover to the new Model Y. The Shanghai Gigafactory, which produces both the Model 3 and Model Y, continues to serve as a dual-purpose hub for domestic and export markets.

In September, Tesla exported 19,287 vehicles from its Shanghai facility, up 19.6% year-on-year but down 25.9% from August, as noted in a CNEV Post report. This is in line with Tesla China’s strategy of prioritizing exports early in each quarter. Including exports, Tesla China’s total wholesale volume reached 90,812 units in September, up 2.82% year-on-year and 9.16% month-on-month.

Model Y still leads

The Tesla Model Y still led the electric vehicle maker’s sales in China with 59,907 units sold wholesale during the month, rising 17.1% from last year, while Model 3 reached 30,905 units, dipping 16.8% year-on-year but up 27% from August. Tesla’s overall market share in China’s NEV segment rose to 5.52%, and its BEV share climbed to 8.66%, modest gains hinting at the company’s resilience in a fiercely competitive market.

Elon Musk teases ‘Banish’ feature to pair perfectly with Summon

Tesla has long promised the possibility of completely hands-off parking: arrive, drop off at the entrance, the car parks itself, and the car retrieves you at the end of your visit.

Elon Musk has once again teased the “Banish” feature that could come to Tesla vehicles in the near future. It would be a perfect pairing to the popular Assisted Smart Summon (ASS), which the company launched earlier this year.

Banish has been something Tesla has teased for years. The company has promised the possibility of completely hands-off parking: arrive, drop off at the entrance, the car parks itself, and the car retrieves you at the end of your visit.

Ultimately, even though it is technically a driverless feature, Tesla has not refined its parking portion of the Full Self-Driving (Supervised) suite enough to release Banish to the public.

Tesla recently started performing specified parking tasks at the driver’s discretion. In the FSD (Supervised) v14.1 release, Tesla has added the ability to pick your parking scenario. Drivers can choose a Charger, Parking Lot, Curbside, Street, Driveway, or Parking Garage.

To achieve Banish, Tesla would have to gather enough data with these scenarios to then gain the capability to park after dropping vehicle occupants off.

However, CEO Elon Musk recently hyped Banish to the point of stating Teslas will be capable of it “in the near future.”

His remark came in response to a video where FSD v14.1 drove around a Costco parking lot for twenty minutes looking for a spot:

Summon is a feature that has given Tesla its challenges, but the release of Assisted Smart Summon (ASS) has improved some of its capabilities.

I tested it after receiving v14.1, and it did a great job of taking the correct route and driving safely to my location:

There will likely be some time between now and when Tesla is able to release Banish. As previously noted, Tesla will need to collect enough data from real-world scenarios and obtain a proven track record of being able to handle lots and parking in a variety of environments while supervised.
