As SpaceX teams slowly prepare the first orbital-class Starship and Super Heavy booster for the next-generation rocket’s first full-stack launch, the company has simultaneously begun assembling a second ship/booster pair. However, it’s clear that orbital pad construction remains a priority.

Known as Ship 20 and Booster 4, the two stages of the first orbital-class Starship first arrived at the launch site in early August. Only eight weeks later has Starship S20 finally become the first of the pair to attempt and complete one of two crucial proof tests, opening the door for one or several Raptor static fires in the coming week or two. Meanwhile, Booster 4 has had all 29 of its Raptor engines installed, uninstalled, and reinstalled and twice been placed on and removed from Starbase’s orbital launch mount in the same time frame but has yet to attempt any proof testing.

Despite the apparent delays and challenges slowing Ship 20 and Booster 4’s test debuts and two plodding FAA reviews that appear all but guaranteed to preclude an orbital launch attempt in 2021, though, SpaceX has recently begun assembling a second two-stage Starship.

Save for Starhopper back in 2019, no Starship or Super Heavy prototype has spent nearly as long at the launch site without a single test as Ship 20 and Booster 4 have. To an extent, there have likely been some technical delays while assembling, outfitting, and working with two first-of-their-kind prototypes. Still, the difference between past vehicles like Starship SN15 and Super Heavy Booster 3 are so stark that some portion of the testing delays almost has to be a conscious decision made by SpaceX.

To be able to fully proof and static fire test Super Heavy B4, SpaceX first needs to plumb, wire, and outfit Starbase’s orbital launch mount and complete a majority of the orbital pad’s massive tank farm. However, the orbital pad and its many unfinished systems are situated just a thousand (~300m) east of the suborbital launch site and Starship test facilities, which are complete and ready for testing. To test a Starship at those facilities, SpaceX has to entirely clear the pad of personnel – now several hundred people at the peak of construction – for 6-12+ hours.

The implication is that SpaceX management effectively chose to rip off the bandage now rather than later, sacrificing timely testing of Starship S20 to allow a near-total focus on orbital pad construction and activation over the last ~8 weeks. It’s hard to say if that’s paid off but the fact that SpaceX has chosen this particular moment to begin assembling the next orbital-class Starship and Super Heavy suggests that a clearer plan is starting to come together.

B4/S20, meet B5/S21

Parts of Starship S21 and Super Heavy B5 have been floating around Starbase’s build site for weeks. There was a multi-week period, for example, where the site’s massive high bay was effectively unused – clearly a conscious choice given SpaceX’s history of Starship prototype production earlier this year and late last. Parts of Super Heavy B5 were likely ready for assembly (i.e. stacking) by mid to late August. The ‘mid bay’ used for Starship tank section assembly has been similarly underutilized for even longer – only recently accepting its first Starship S21 section after supporting assembly of the orbital pad’s final storage tank.

Booster 5 is roughly half-finished.

Instead, Booster 5 stacking began around September 15th. At the current rate of assembly, which has slowed down considerably in the last week, SpaceX’s second flightworthy Super Heavy could reach its full 69m (~225 ft) height as early as mid-October. Starship S20 likely won’t be far behind. Further, thanks to SpaceX’s preferred style of continuous improvement, Booster 5 and Ship 21 production already appear well on track to outpace Booster 4 and Ship 20. With B5, rather than installing a range of external equipment (avionics, wiring, plumbing) after assembly is finished, SpaceX appears to be completing some of those subsystems during stacking, potentially speeding up final assembly by 1-2+ weeks. With S21, SpaceX has begun outfitting the Starship’s nose cone with heat shield tiles far earlier in the assembly process than it did with S20.

Given that it has taken SpaceX the better part of a month to finish and spot-fix Starship S20’s heat shield since the prototype’s second trip to the test site, taking those lessons learned to heart and getting Starship S21’s heat shield installation right on the first try could cut weeks from final assembly.

In the meantime, after completing Ship 20’s first cryoproof test on September 29th, SpaceX will hopefully be able to kick off the first six-engine Raptor static fire test campaign within the next week or so. With any luck, the start of B5/S21 assembly also means that the orbital launch pad is nearly ready to support Super Heavy B4’s first proof tests, even if static fires with anything close to a full set of 29 Raptors appear to be weeks away. Regardless, it looks like it won’t be long before SpaceX will be juggling two pairs of orbital-class Starships and Super Heavy boosters.

Rivian and Amazon announce huge milestone with EDV

The companies announced today that they had officially launched the EDV in Canada for Amazon, as the first 50 units are out and about in Vancouver, and the company said it was “marking an exciting milestone in our five-year history of operations in Canada.”

Rivian and Amazon have announced a huge milestone with their Electric Delivery Vehicle (EDV), the van that the two companies developed for the e-commerce giant to sustainably deliver packages to customers.

The EDV was first unveiled back in September 2019, when Amazon announced a massive investment in Rivian and placed an order for 100,000 electric vans, aiming to deploy them by 2030 as part of the company’s sustainability goals.

Production started in 2021 in Normal, Illinois, and entered Amazon’s fleet of active delivery vehicles over the Summer of 2022. Amazon kept the initial vehicles in major metropolitan areas and eventually started rolling them out to more delivery hubs across the United States.

In December 2024, the companies announced they had successfully deployed 20,000 EDVs across the U.S. In the first half of this year, 10,000 additional vans were delivered, and Amazon’s fleet had grown to 30,000 EDVs by mid-2025.

Amazon’s fleet of EDVs continues to grow rapidly and has expanded to over 100 cities in the United States. However, it has just reached a new milestone, and it has nothing to do with the size of its fleet.

The companies announced today that they had officially launched the EDV in Canada for Amazon, as the first 50 units are out and about in Vancouver, and the company said it was “marking an exciting milestone in our five-year history of operations in Canada.”

The EDV is a model that is exclusive to Amazon, but Rivian sells the RCV, or Rivian Commercial Van, openly. It detailed some of the pricing and trim options back in January when it confirmed it had secured orders from various companies, including AT&T.

The RCV starts at $83,000, and is one of the few electric vans on the market that is suitable for package delivery in a commercial setting because of its build and interior features.

However, it also seems to be a great option as a service vehicle for companies, which is likely why AT&T is going to utilize it.

Tesla’s biggest rival in China reported a big profit decline once again

Published

Tesla’s biggest rival in China reported a big decline in its profitability for the second straight quarter, and a loss of one-third compared to the same quarter last year.

BYD overtook Tesla as the best-selling EV maker in China in the fourth quarter of 2023, finally surpassing the company in terms of sales in the region.

Is Tesla really losing to BYD, or just playing a different game?

The Chinese market is one of the most competitive in the world, especially for EVs, as the industry is healthy with young and scrappy companies looking to sell the best possible tech in their vehicles.

BYD reported its earnings on Thursday and said that its profit had slumped by 33 percent compared to the same quarter last year. For this year’s third quarter, BYD reported a net profit of 7.8 billion yuan ($1.1 billion), a 32.6 percent decrease compared to the same period in 2024.

Its revenue was 195 billion yuan ($27.4 billion), which was only a 3 percent decrease compared to Q3 2024.

The drop in profits and revenue can mostly be attributed to the ongoing growth of competition in the Chinese market. The increased competition in China has pushed companies to turn to overseas markets in response, according to CnEVPost.

BYD is one of those companies, and it is attempting to push sales upward by entering new markets, especially in Europe, where the company sold more than 13,000 units in EU countries in September alone.

This was a 272 percent increase year over year, a major piece of evidence that it has a lot of potential in foreign markets.

The drop in financial figures is likely a short-term issue for BYD, as it has already established itself as a formidable competitor to many companies in many markets. In Q1, it reported an increase in profit by 100 percent compared to the same time span the year prior.

As it works to expand to even more markets in the world, it will continue to build upon its already-solid reputation.

GM takes latest step to avoid disaster as EV efforts get derailed

There was an even larger step taken this morning, as the Detroit Free Press reported that GM was idling its Factory Zero plant in Michigan until late November, placing about 1,200 workers on indefinite layoff status.

General Motors has taken its latest step to avoid financial disaster as its electric vehicle efforts have been widely derailed.

GM’s electric vehicle manufacturing efforts started off hot, and CEO Mary Barra seemed to have a real hold on how the industry and consumers were starting to evolve toward sustainable powertrains. Even former President Joe Biden commended her as being a major force in the global transition to EVs.

However, the company’s plans have not gone as they’ve drawn them up. GM has reported some underwhelming delivery figures in recent quarters, and with the loss of the $7,500 tax credit, the company is planning for what is likely a substantial setback in its entire EV division.

Earlier this month, the company reported it would include a $1.6 billion charge in its quarterly earnings results from EV investments. It was the first true sign that things with GM’s EV projects were going to slow down.

There was an even larger step taken this morning, as the Detroit Free Press reported that GM was idling its Factory Zero plant in Michigan until late November, placing about 1,200 workers on indefinite layoff status.

This is in addition to the 280 employees it has already laid off after production cuts that happened earlier this year at the Detroit-Hamtramck plant.

After November 24, GM will bring back 3,200 people to work until January 5 to operate both shifts. On January 5, GM is expected to keep 1,200 workers on indefinite layoff.

GM is not the only legacy automaker to make a move like this, as Ford has also started to make a move that reflects a cautious tone regarding how far and how committed it can be to its EV efforts.

After the tax credit was lost, it seemed to be a game of who would be able to float their efforts longest without the government’s help. Tesla CEO Elon Musk long said that the loss of these subsidies would help the company and hurt its competitors, and so far, that is what we are seeing.

Elon Musk was right all along about Tesla’s rivals and EV subsidies

However, Tesla still has some things to figure out, including how its delivery numbers will be without the tax credit. Its best quarter came in Q3 as the credit was expiring, but Tesla did roll out some more affordable models after the turn of the quarter.
