SpaceX swaps Starship Raptor engine for one last pre-flight test

On the same day SpaceX stacked a flightworthy Starship prototype to its full height for the first time, the company decided to swap one of the rocket’s three Raptor engines ahead of one last major pre-flight test.

Curiously, at the same time as SpaceX engineers and technicians were removing Raptor serial number 39 (SN39) from Starship SN8, a second Raptor – SN36 – was briefly removed from a specialized transport truck. Once SN39 was removed, both it and SN36 were loaded onto a separate flatbed and carefully driven back to SpaceX’s Boca Chica Starship factory.

It’s unclear why SpaceX seemingly aborted October 22nd’s in situ Raptor replacement but Raptor SN36 (presumed) was ultimately installed in SN39’s place on Starship around midnight on October 23rd. Regardless of why, SpaceX did what it always does and reacted almost immediately, quickly replacing a Raptor engine to keep Starship SN8 on schedule for what could be its last test before an ambitious 15 km (50,000 ft) launch debut.

According to SpaceX CEO Elon Musk, Starship SN8 is expected to complete two separate triple-Raptor static fire tests before the company is ready to commit the rocket to such an ambitious flight test. SN8 completed what was the Starship and Raptor programs’ first multi-engine static fire test ever a mere two days before SpaceX began installing the rocket’s nosecone – a milestone curiously absent from Musk’s tweet.

It’s possible that Musk was speaking under the assumption that SN8 would be fully assembled before it began static fire operations, with “checkouts” referring to touch-free inspections between two back-to-back Raptor tests to simulate the in-flight reignition Starship SN8 will need to perform during its flight debut. If that’s the case, SN8 may need to pass two more static fires before being cleared for flight.

Either way, SpaceX has already scheduled unlabeled Boca Chica road closures from 8am to 11pm CDT (UTC-5) on October 28th and 29th and 5am to 11am CDT on October 30th. Given the length of those closures, their purpose is almost certainly to support Starship SN8’s next static fire test campaign. With SN8’s nose now fully installed, SpaceX will likely focus on testing the liquid oxygen header tank located in the tip to ensure that the smaller sub-tanks meant to hold Starship’s landing propellant are working as expected and capable of supplying three thirsty Raptor engines.

Tesla Giga Berlin is still ramping production to meet Model Y demand: plant manager

Tesla Gigafactory Berlin has expanded to two full shifts, as per the facility’s plant manager, and a lot of it is due to Model Y demand.

Tesla Gigafactory Berlin has expanded to two full shifts, as per the facility’s plant manager, and a lot of it is due to Model Y demand. While registrations in some countries such as Sweden have fallen sharply this year, the company’s sales in other key territories have been rising. 

Giga Berlin shifts to two shifts

Giga Berlin factory manager André Thierig told the DPA that the facility has been running two shifts since September to manage a surge in global orders. And due to the tariff dispute with the United States, vehicles that are produced at Giga Berlin are now being exported to Canada. 

“We deliver to well over 30 markets and definitely see a positive trend there,” Thierig said.

Despite Giga Berlin now having two shifts, the facility’s production still needs to ramp up more. This is partly due to the addition of the Tesla Model Y Performance and Standard, which are also being produced in the Grunheide-based factory. Interestingly enough, Giga Berlin still only produces the Model Y, unlike other factories like Gigafactory Texas, the Fremont Factory, and Gigafactory Shanghai, which produce more than one type of vehicle. 

Norway’s momentum

Norway, facing an imminent tax increase on cars, has seen a historic spike in Tesla purchases as buyers rush to secure deliveries before the change takes effect, as noted in a CarUp report. As per recent reports, Tesla has broken Norway’s all-time annual sales record this month, beating Volkswagen’s record that has stood since 2016.

What is rather remarkable is the fact that Tesla was able to achieve so much in Norway with one hand practically tied behind its back. This is because the company’s biggest sales draw, FSD, remains unavailable in the country. Fortunately, Tesla is currently hard at work attempting to get FSD approved for Europe, a notable milestone that should spur even more vehicle sales in the region.

Tesla launches crazy Full Self-Driving free trial: here’s how you can get it

Tesla is launching a crazy Full Self-Driving free trial, which will enable owners who have not purchased the suite outright to try it for 30 days.

There are a handful of stipulations that will be needed in order for you to qualify for the free trial, which was announced on Thursday night.

Tesla said the trial is for v14, the company’s latest version of the Full Self-Driving suite, and will be available to new and existing Model S, Model 3, Model X, Model Y, and Cybertruck owners, who will have the opportunity to try the latest features, including Speed Profiles, Arrival Options, and other new upgrades.

You must own one of the five Tesla models, have Full Self-Driving v14.2 or later, and have an eligible vehicle in the United States, Puerto Rico, Mexico, or Canada.

The company said it is a non-transferable trial, which is not redeemable for cash. Tesla is reaching out to owners via email to give them the opportunity to enable the Full Self-Driving trial.

Those who are subscribed to the monthly Full Self-Driving program are eligible, so they will essentially get a free month of the suite.

Once it is installed, the trial will begin, and the 30-day countdown will begin.

Tesla is making a major push to increase its Full Self-Driving take rate, as it revealed that about 12 percent of owners are users of the program during its recent earnings call.

Tesla CFO Vaibhav Taneja said during the call:

“We feel that as people experience the supervised FSD at scale, demand for our vehicles, like Elon said, would increase significantly. On the FSD adoption front, we’ve continued to see decent progress. However, note that the total paid FSD customer base is still small, around 12% of our current fleet.”

Earlier today, we reported on Tesla also launching a small-scale advertising campaign on X for the Full Self-Driving suite, hoping to increase adoption.

Tesla Full Self-Driving warrants huge switch-up on essential company strategy

It appears most people are pretty content with the subscription program. It costs just $99 a month, in comparison to the $8,000 fee it is for the outright purchase.

Tesla Full Self-Driving warrants huge switch-up on essential company strategy

Tesla Full Self-Driving has warranted a huge switch-up on an essential company strategy as the automaker is hoping to increase the take rate of the ADAS suite.

Unlike other automotive companies, Tesla has long been an outlier, as it has famously ditched a traditional advertising strategy in favor of organic buzz, natural word-of-mouth through its production innovation, and utilizing CEO Elon Musk’s huge social media presence to push its products.

Tesla has taken the money that it would normally spend on advertising and utilized it for R&D purposes. For a long time, it yielded great results, and ironically, Tesla saw benefits from other EV makers running ads.

Tesla counters jab at lack of advertising with perfect response

However, in recent years, Tesla has decided to adjust this strategy, showing a need to expand beyond its core enthusiast base, which is large, but does not span over millions and millions as it would need to fend off global EV competitors, which have become more well-rounded and a better threat to the company.

In 2024 and 2025, Tesla started utilizing ads to spread knowledge about its products. This is continuing, as Full Self-Driving ads are now being spotted on social media platforms, most notably, X, which is owned by Musk:

Interestingly, Tesla’s strategy on FSD advertising is present in Musk’s new compensation package, as the eleventh tranche describes a goal of achieving 10 million active paid FSD subscriptions.

Full Self-Driving is truly Tesla’s primary focus moving forward, although it could be argued that it also has a special type of dedication toward its Optimus robot project. However, FSD will ultimately become the basis for the Robotaxi, which will enable autonomous ride-sharing across the globe as it is permitted in more locations.

Tesla has been adjusting its advertising strategy over the past couple of years, and it seems it is focused on more ways to spread awareness about its products. It will be interesting to see if the company will expand its spending even further, as it has yet to put on a commercial during live television.

We wouldn’t put it out of the question, at least not yet.
