SpaceX frees up orbital launch site for upgraded Super Heavy booster
After ‘destacking’ Starship S20, SpaceX has officially removed Super Heavy Booster B4 from Starbase’s lone orbital launch mount – and likely for the last time.
Standing about 69 meters (~225 ft) tall and likely weighing at least 200 tons (~440,000 lb), Booster 4 has been at SpaceX’s Starbase orbital launch site (OLS) for more than six months – only slightly less time than Starship S20, which it was expected to eventually launch into space. Several of those months were spent sitting on top of the pad’s 22-meter-tall (~70 ft) orbital launch mount, which has been slowly but surely outfitted, modified, and tweaked into something capable of supporting basic Super Heavy testing.
All told, Booster 4 has completed more than half a dozen cryogenic proof tests but never appeared to graduate to more complex and valuable wet dress rehearsals – replacing neutral liquid nitrogen with flammable liquid methane and oxygen propellant to simulate preparations for a real launch. Most importantly, despite having had 29 proof-tested Raptor engines installed for months, Super Heavy B4 never even attempted to static fire one of those engines, where a successful 29-engine static fire is probably the single most important test a booster will need to pass to be cleared for flight.
As a result, the writing has been on the wall for Booster 4 for quite a while. Instead of investing in testing the booster, which has a somewhat outdated two-off design, it appears that SpaceX will instead transfer crucial qualification testing to Super Heavy Booster 7. As previously discussed, on top of general improvements to process and fit and finish throughout, Booster 7 is substantially different from Booster 4.
“Super Heavy B7 and Starship S24 feature a wide range of design changes, including substantially modified header tanks, an entirely new nosecone design, new layouts for secondary systems (pressurization, avionics, heat exchangers, etc.), and more. Most importantly, their thrust structures – giant ‘pucks’ machined out of steel – have been tweaked to support new Raptor V2 engines instead of the Raptor V1 and V1.5 engines that have been installed and tested on all Starship and Super Heavy prototypes to date.”

One could easily argue that SpaceX should have better used the months upon months that Super Heavy B4 sat inactive and largely untouched at Starbase’s launch facilities – instead using that time to perform basic static fire testing that could even have even been done at one of two suborbital launch mounts if the orbital mount wasn’t ready. Nonetheless, irrespective of that seemingly wasted opportunity, it makes sense that SpaceX now wants to cut its losses and redirect its focus to prototypes with extensive upgrades and improvements.
Up next, SpaceX will continue to stack and outfit Starship S24. Already fully stacked, Super Heavy B7 could feasibly be rolled to the orbital launch site at almost any point within the next week or two to begin simpler pneumatic and cryogenic proof testing, followed by Raptor V2 engine installation and the start of static fire testing.

Tesla China delivery centers look packed as 2025 comes to a close
Needless to say, it appears that Tesla China seems intent on ending 2025 on a strong note.
Tesla’s delivery centers in China seem to be absolutely packed as the final days of 2025 wind down, with photos on social media showing delivery locations being filled wall-to-wall with vehicles waiting for their new owners.
Needless to say, it appears that Tesla China seems intent on ending 2025 on a strong note.
Full delivery center hints at year-end demand surge
A recent image from a Chinese delivery center posted by industry watcher @Tslachan on X revealed rows upon rows of freshly prepared Model Y and Model 3 units, some of which were adorned with red bows and teddy bears. Some customers also seem to be looking over their vehicles with Tesla delivery staff.
The images hint at a strong year-end push to clear inventory and deliver as many vehicles as possible. Interestingly enough, several Model Y L vehicles could be seen in the photos, hinting at the demand for the extended wheelbase-six seat variant of the best-selling all-electric crossover.
Strong demand in China
Consumer demand for the Model Y and Model 3 in China seems to be quite notable. This could be inferred from the estimated delivery dates for the Model 3 and Model Y, which have been extended to February 2026 for several variants. Apart from this, the Model Y and Model 3 also continue to rank well in China’s premium EV segment.
From January to November alone, the Model Y took China’s number one spot in the RMB 200,000-RMB 300,000 segment for electric vehicles, selling 359,463 units. The Model 3 sedan took third place, selling 172,392. This is quite impressive considering that both the Model Y and Model 3 are still priced at a premium compared to some of their rivals, such as the Xiaomi SU7 and YU7.
With delivery centers in December being quite busy, it does seem like Tesla China will end the year on a strong note once more.

Tesla Giga Berlin draws “red line” over IG Metall union’s 35-hour week demands
Factory manager André Thierig has drawn a “red line” against reducing Giga Berlin’s workweek to 35 hours, while highlighting that Tesla has actually increased its workers’ salaries more substantially than other carmakers in the country.
Tesla Giga Berlin has found itself in a new labor dispute in Germany, where union IG Metall is pushing for adoption of a collective agreement to boost wages and implement changes, such as a 35-hour workweek.
In a comment, Giga Berlin manager André Thierig drew a “red line” against reducing Giga Berlin’s workweek to 35 hours, while highlighting that Tesla has actually increased its workers’ salaries more substantially than other carmakers in the country.
Tesla factory manager’s “red line”
Tesla Germany is expected to hold a works council election in 2026, which André Thierig considers very important. As per the Giga Berlin plant manager, Giga Berlin’s plant expansion plans might be put on hold if the election favors the union. He also spoke against some of the changes that IG Metall is seeking to implement in the factory, like a 35-hour week, as noted in an rbb24 report.
“The discussion about a 35-hour week is a red line for me. We will not cross it,” Theirig said.
“(The election) will determine whether we can continue our successful path in the future in an independent, flexible, and unbureaucratic manner. Personally, I cannot imagine that the decision-makers in the USA will continue to push ahead with the factory expansion if the election results favor IG Metall.”
Giga Berlin’s wage increase
IG Metall district manager Jan Otto told the German news agency DPA that without a collective agreement, Tesla’s wages remain significantly below levels at other German car factories. He noted the company excuses this by referencing its lowest pay grade, but added: “The two lowest pay grades are not even used in car factories.”
In response, Tesla noted that it has raised the wages of Gigafactory Berlin’s workers more than their German competitors. Thierig noted that with a collective agreement, Giga Berlin’s workers would have seen a 2% wage increase this year. But thanks to Tesla not being unionized, Gigafactory Berlin workers were able to receive a 4% increase, as noted in a CarUp report.
“There was a wage increase of 2% this year in the current collective agreement. Because we are in a different economic situation than the industry as a whole, we were able to double the wages – by 4%. Since production started, this corresponds to a wage increase of more than 25% in less than four years,” Thierig stated.

Tesla is seeing a lot of momentum from young Koreans in their 20s-30s: report
From January to November, young buyers purchased over 21,000 Teslas, putting it far ahead of fellow imported rivals like BMW and Mercedes-Benz.
Tesla has captured the hearts of South Korea’s 20s-30s demographic, emerging as the group’s top-selling imported car brand in 2025. From January to November, young buyers purchased over 21,000 Teslas, putting it far ahead of fellow imported rivals like BMW and Mercedes-Benz.
Industry experts cited by The Economist attributed this “Tesla frenzy” to fandom culture, where buyers prioritize the brand over traditional car attributes, similar to snapping up the latest iPhone.
Model Y dominates among young buyers
Data from the Korea Imported Automobile Association showed that Tesla sold 21,757 vehicles to the 20s-30s demographic through November, compared to BMW’s 13,666 and Mercedes-Benz’s 6,983. The Model Y led the list overwhelmingly, with variants like the standard and Long Range models topping purchases for both young men and women.
Young men bought around 16,000 Teslas, mostly Model Y (over 15,000 units), followed by Model 3. Young women followed a similar pattern, favoring Model Y (3,888 units) and Model 3 (1,083 units). The Cybertruck saw minimal sales in this group.
The Model Y’s appeal lies in its family-friendly SUV design, 400-500 km range, quick acceleration, and spacious cargo, which is ideal for commuting and leisure. The Model 3, on the other hand, serves as an accessible entry point with lower pricing, which is valuable considering the country’s EV subsidies.
The Tesla boom
Experts described Tesla’s popularity as “fandom culture,” where young buyers embrace the brand despite criticisms from skeptics. Professor Lee Ho-geun called Tesla a “typical early adopter brand,” comparing purchases to iPhones.
Professor Kim Pil-soo noted that young people view Tesla more as a gadget than a car, and they are likely drawn by marketing, subsidies, and perceived value. They also tend to overlook news of numerous recalls, which are mostly over-the-air software updates, and controversies tied to the company.
Tesla’s position as Korea’s top import for 2025 seems secured. As noted by the publication, Tesla’s December sales figures have not been reported yet, but market analysts have suggested that Tesla has all but secured the top spot among the country’s imported cars this year.
