After a relatively relaxed period of production and testing, SpaceX’s South Texas Starship factory is practically overflowing with new and flight-proven ships as the company prepares for the rocket’s next major tests.

Even before the one-off Starship Mk1 prototype failed a pressure test late last year, SpaceX was in the process of upgrading its Boca Chica production facilities and refining the ship’s design and manufacturing processes. Starship SN1, the first prototype built as part of that upgrade, rolled to the launch pad on February 25th, 2020, followed by Starship SN2 (turned into a test tank) just a week or so later. Starship SN3 and SN4 would both follow in early and late April, ultimately ending with the latter prototype’s spectacularly violent demise in late May.

Over the remaining three or so months, the pace of testing has slowed a bit as SpaceX’s Starship development program enters the full-scale flight testing phase. Starship SN5 began testing on July 1st, followed by SN6 around six weeks later. Both prototypes successfully hopped just 30 days apart. Now, although SpaceX still plans to hop SN5 a second time and may hop SN6 twice, too, the Starship program’s focus has shifted to high-altitude, high-velocity flight tests and the adoption of a new steel alloy.

Presumably in anticipation of a learning curve as that new steel alloy begins to be tested at full-scale for the first times, SpaceX is churning out Starship prototypes at an unprecedented pace. Intriguingly, that production ramp is hinged upon the assumption that a 304L-class steel alloy (compared to the 301 stainless steel used to build SN1 through SN6) will be as good or better than 301 steel in every significant way.

Currently, that assumption isn’t entirely baseless but is still built upon the success of Starship SN7, SpaceX’s first 304L test tank. SpaceX never confirmed its results but it’s believed that that test tank – more of a material demonstrator than an actual structural Starship prototype – surpassed all previous pressure records before it burst in June.

Given that SN7 performed quite well, it’s at least a bit less surprising that SpaceX is hinging months of work and at least four full-scale Starship prototypes on an otherwise unproven steel alloy. The next big test for 304L Starships will be a second test tank known as SN7.1. Rolled to the test site on September 7th, essentially as soon as Starship SN6 was safed and returned to the factory after its hop debut, SN7.1 is significantly more complex than its sibling and will test a ~304L Raptor mount (thrust puck) and skirt section. The forces and general conditions those new parts will be subjected to are substantially different than most of what SN7 was subjected to, meaning that there is a chance that 304L steel is less optimal in different scenarios.

With any luck, SN7.1’s test campaign – scheduled to begin as early as 9pm CDT (UTC-5), September 10th (today) – will be a flawless success, proving that SpaceX’s new steel alloy is universally superior to 301 for Starship-related applications. If that’s the case, Starship SN8 – the first full new-alloy prototype – will likely be fully outfitted with a nosecone and header tanks before beginning acceptance testing.

Eventually, if SN7.1 aces its tests and SN8 performs well during preflight preparations, Starship SN8 could become the first prototype to launch with a full nose, header tanks, and flaps, as well as the first to fly with three Raptor engines. If Starship SN8 fails for any reason or is damaged during testing, though, it appears that SpaceX will have no shortage of ships built out of the same new steel alloy to choose from.

In just the last ten days, labeled parts and rings for Starships SN9, SN10, and SN11 have all been spotted, implying that SpaceX is concurrently building at least four new Starships. Notably, both Starships SN9 and SN11 already appear to have some of the studs needed for heat shield tile installation affixed to sections of their steel hulls. Based on the sheer number of steel ring stacks spotted over the last week, it’s also safe to assume that SN9’s tank section (and possibly SN10’s, too) is largely prefabricated.

The first labeled Starship SN11 rings were spotted on September 9th. (NASASpaceflight – bocachicagal)

Assuming two of the in-work nosecones are ultimately meant for flight, SpaceX may already have enough hardware on hand to fully assemble two Starships (presumably SN8 and SN9) – including nosecones, header tanks, nose rings, and flaps. It’s safe to say that if SN7.1 achieves its goals, preparations for the first triple Raptor hop, 20 km (~12 mi) test flight, and skydiver-style landing attempt could come together incredibly quickly.

Tesla Cybercab undergoes winter testing as Elon Musk reiterates production start date

CEO Elon Musk confirmed the timeline in a recent post on X, while Tesla’s official social media accounts separately revealed that Cybercab prototypes are now undergoing winter testing in Alaska.

Tesla has reiterated that production of its fully autonomous Cybercab is set to begin in April, even as the company continues expanding real-world testing of the vehicle. 

CEO Elon Musk confirmed the timeline in a recent post on X, while Tesla’s official social media accounts separately revealed that Cybercab prototypes are now undergoing winter testing in Alaska.

Musk confirms April Cybercab initial production

In a post on X, Musk reiterated that Cybercab production is scheduled to begin in April, reiterating his guidance about the vehicle’s manufacturing timeline. Around the same time, Tesla shared images showing the Cybercab undergoing cold-weather testing in Alaska. Interestingly enough, the Cybercab prototypes being tested in Alaska seemed to be equipped with snow tires. 

Winter testing in Alaska suggests Tesla is preparing the Cybercab for deployment across a wide range of climates in the United States. Cold temperatures, snow, ice, and reduced traction present some of the most demanding scenarios for autonomous systems, making Alaska a logical proving ground for a vehicle designed to operate without a human driver.

Taken together, Musk’s production update and Tesla’s testing post indicate that while the Cybercab is nearing the start of manufacturing, validation efforts are still actively ramping to ensure reliability in real-world environments.

What early Cybercab production might look like

Musk has previously cautioned that the start of Cybercab manufacturing will be slow, reflecting the challenges of launching an all-new vehicle platform. In a recent comment, Musk said initial production typically follows an S-curve, with early output constrained by how many new parts and processes are involved.

According to Musk, both Cybercab and Optimus fall into this category, as “almost everything is new.” As a result, early production rates are expected to be very deliberate before eventually accelerating rapidly as manufacturing processes mature.

“Initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” Musk wrote in a post on X.

Tesla to increase Full Self-Driving subscription price: here’s when

Published

Tesla will increase its Full Self-Driving subscription price, meaning it will eventually be more than the current $99 per month price tag it has right now.

Already stating that the ability to purchase the suite outright will be removed, Tesla CEO Elon Musk said earlier this week that the Full Self-Driving subscription price would increase when its capabilities improve:

“I should also mention that the $99/month for supervised FSD will rise as FSD’s capabilities improve. The massive value jump is when you can be on your phone or sleeping for the entire ride (unsupervised FSD).”

This was an expected change, especially as Tesla has been hinting for some time that it is approaching a feature-complete version of Full Self-Driving that will no longer require driver supervision. However, with the increase, some are concerned that they may be priced out.

$99 per month is already a tough ask for some. While Full Self-Driving is definitely worth it just due to the capabilities, not every driver is ready to add potentially 50 percent to their car payment each month to have it.

While Tesla has not revealed any target price for FSD, it does seem that it will go up to at least $150.

Additionally, the ability to purchase the suite outright is also being eliminated on February 14, which gives owners another reason to be slightly concerned about whether they will be able to afford to continue paying for Full Self-Driving in any capacity.

Some owners have requested a tiered program, which would allow people to pay for the capabilities they want at a discounted price.

Unsupervised FSD would be the most expensive, and although the company started removing Autopilot from some vehicles, it seems a Supervised FSD suite would still attract people to pay between $49 and $99 per month, as it is very useful.

Tesla will likely release pricing for the Unsupervised suite when it is available, but price increases could still come to the Supervised version as things improve.

This is not the first time Musk has hinted that the price would change with capability improvements, either. He’s been saying it for some time. In 2020, he even said the value of FSD would “probably be somewhere in excess of $100,000.”

Tesla starts removing outright Full Self-Driving purchase option at time of order

Published

Tesla has chosen to axe the ability to purchase Full Self-Driving outright from a select group of cars just days after CEO Elon Musk announced the company had plans to eliminate that option in February.

The company is making a clear-cut stand that it will fully transition away from the ability to purchase the Full Self-Driving suite outright, a move that has brought differing opinions throughout the Tesla community.

Earlier this week, the company also announced that it will no longer allow buyers to purchase Full Self-Driving outright when ordering a pre-owned vehicle from inventory. Instead, that will be available for $99 per month, the same price that it costs for everyone else.

The ability to buy the suite for $8,000 for a one-time fee at the time of order has been removed:

This is a major move because it is the first time Tesla is eliminating the ability to purchase FSD outright for one flat fee to any of its vehicles, at least at the time of purchase.

It is trying to phase out the outright purchase option as much as it can, preparing people for the subscription-based service it will exclusively offer starting on February 14.

In less than a month, it won’t be available on any vehicle, which has truly driven some serious conversation from Tesla owners throughout the community.

There’s a conflict, because many believe that they will now lose the ability to buy FSD and not pay for it monthly, which is an attractive offer. However, others believe, despite paying $8,000 for FSD, that they will have to pay more money on top of that cost to get the unsupervised suite.

Additionally, CEO Elon Musk said that the FSD suite’s subscription price would increase over time as capabilities increase, which is understandable, but is also quite a conflict for those who spent thousands to have what was once promised to them, and now they may have to pay even more money.
