First noticed by NASASpaceflight.com forum member “exilon”, SpaceX appears to have selected off-the-shelf Tesla battery packs as the power storage method of choice for its Starship Mk1 prototype, currently in the midst of a busy period of integration

Potentially taken directly from Tesla Model S/X powertrains otherwise headed for recycling, SpaceX technicians have spent the last 24 or so hours attaching numerous battery packs to part of a Starship subsystem known as header tanks. This is the latest addition to SpaceX and Tesla’s relatively close relationship – the two have begun to work together to solve challenges with materials science, batteries, and more within the last 12-24 months.

While initially surprising, the appearance of battery packs quite literally taken from Tesla Model S/X vehicles or their Gigafactory assembly line actually makes a lot of sense. By using prepackaged, off-the-shelf battery systems with industry-leading power management capabilities, SpaceX is probably saving a huge amount of time, money, and effort. If the battery packs were already nearing the end of their useful automotive lives, the net cost could very well approach zero, aside from what looks like a minimal mounting brace. It’s possible that SpaceX has even pursued modifying and certifying large Tesla-derived battery packs for use on orbital Starship missions.

These battery packs were spotted by an eagle-eyed forum user who was first to recognize the hardware for what it likely was. Per the above photo, SpaceX appears to have joined two self-contained Tesla battery packs into single units that were then installed on a header tank. Knowing that the highest capacity Tesla offers is ~100 kWh, the 2×2 packs could store up to 400 kWh and offer instantaneous power output (ignoring thermal limitations) well into the megawatt (MW) range. It’s unclear if the first header tank also had batteries attached but SpaceX technicians began installing that tank inside Starship’s nose cone on the evening September 22nd. Tank #2 will likely follow in the next 24 hours per Musk’s indication that Starship Mk1 would be stacked to its full height on Wednesday.

For unknown reasons, SpaceX is choosing to mount the ~1000 kg (2200 lb) battery pack pairs directly onto the outside of one of Starship Mk1’s two header tanks. These tanks compliment the rocket prototype’s main propellant tanks and are meant to serve as small reserves of fuel (methane) and oxidizer (oxygen) that can be pressurized independently. During dramatic in-space and in-atmosphere maneuvers, the g-forces exerted on Starship could easily find the vehicle’s propellant pushed away from the ‘bottom’ of its main tanks, creating bubbles or voids that can damage and destroy rocket engines if ingested.

Pressurizing the entirety of the main tanks (a cylinder measuring 9m by ~40m or 30×130 ft) is extremely impractical – hence the need for much smaller header tanks. Falcon 9 boosters are able to sidestep this issue because they are small and light enough (relatively speaking) that cold gas thrusters can efficiently generate the positive Gs needed to safely ignite its engines for recovery and landing maneuvers. Empty, Starship alone will likely weigh no less than 4-6 times as much as a Falcon 9 booster (~25 tons, 55,000 lb).

According to CEO Elon Musk, SpaceX has decided to install those header tanks in the very tip of Starship Mk1’s conical nose to help balance out the vehicle’s center of mass. As a side-effect, SpaceX will have to install feed lines that run the entire length of the spacecraft and protect them with steel aero-covers. It’s unclear if this design choice is necessitated by Starship’s early, prototypical form or if – once outfitted with crew quarters or a functional cargo bay – it’s possible that that added mass will serve as enough of a counterbalance to preclude the need for ballast in the nose.

Tesla breaks Norway’s all-time annual sales record with one month to spare

With November alone delivering 4,260 new registrations, Tesla has cemented its most dominant year ever in one of Europe’s most mature EV markets.

Tesla shattered Norway’s decade-old annual sales record this month, overtaking Volkswagen’s long-standing milestone with over one month still left in the year. Backed by surging demand ahead of Norway’s upcoming VAT changes, Tesla has already registered 26,666 vehicles year-to-date, surpassing Volkswagen’s 2016 record of 26,572 units. 

With November alone delivering 4,260 new registrations month-to-date, Tesla has cemented its most dominant year ever in one of Europe’s most mature EV markets.

Model Y drives historic surge in Norway

Tesla’s impressive momentum has been led overwhelmingly by the Model Y, which accounted for 21,517 of Norway’s registrations this year, as noted in a CarUp report, citing data from Elbil Statistik. The Model 3 followed with 5,087 units, while the Model S and Model X contributed 30 and 19 vehicles, respectively. Even the parallel-imported Cybertruck made the charts with 13 registrations.

Demand intensified sharply through autumn as Norwegian buyers rushed to secure deliveries before the country’s VAT changes take effect in January. The new regulation is expected to add roughly NOK 50,000 to the price of a Model Y, prompting a wave of early purchases that helped lift Tesla beyond the previous all-time record well before year-end. 

With December still ahead, Tesla is positioned to extend its historic lead further. Needless to say, it appears that Norway will prove to be one of Tesla’s strongest markets in Europe.

FSD could be a notable demand driver in 2026

What’s especially interesting about Tesla’s feat in Norway is that the company’s biggest selling point today, Full Self-Driving (Supervised), is not yet available there. Tesla, however, recently noted in a post on X that the Dutch regulator RDW has reportedly committed to issuing a Netherlands national approval for FSD (Supervised) in February 2026

The RDW posted a response to Tesla’s post, clarifying the February 2026 target but stating that FSD’s approval is not assured yet. “The RDW has drawn up a schedule with Tesla in which Tesla is expected to be able to demonstrate that FSD Supervised meets the requirements in February 2026. RDW and Tesla know what efforts need to be made to make a decision on this in February. Whether the schedule will be met remains to be seen in the coming period,” the RDW wrote in a post on its official wesbite.

If FSD (Supervised) does get approved next year, Tesla’s vehicles could gain a notable advantage over competitors, as they would be the only vehicles on the market capable of driving themselves on both inner-city streets and highways with practically no driver input.

Tesla Full Self-Driving v14.2’s best new feature is not what you think

Tesla Full Self-Driving v14.2 rolled out late last week to Early Access Program (EAP) members, but its best feature is not what you think.

While Tesla has done a great job of refining the performance of the Full Self-Driving suite with the latest update, there are some other interesting additions, including one that many owners have requested for some time.

Upon the release of v14.2, many owners recognized the Blue Dot next to the Autopilot tab in Vehicle Settings, notifying them of a new feature. What was included as a new feature in the new update was a Full Self-Driving stats feature, which now will show you how many miles you’ve traveled in total, and how many of those miles were driven using FSD:

The feature seems to be more of a bragging rights thing than anything, but it will also give drivers a good idea of how many miles they are using Full Self-Driving for. Those who use telematics-based insurance services will also be able to run experiments of their own, and could determine whether their premiums are impacted by the use of Full Self-Driving, and whether it is more advantageous to use over manual driving.

Tesla rolled out numerous other improvements with Tesla Full Self-Driving v14.2, most notably, the company seems to have resolved previous complaints about brake stabbing and hesitation. This was a major complaint in v14.1, but Tesla has seemed to resolve it with this newest branch of the FSD suite.

There were also improvements in overall operation, and it was notably smoother than past versions. Speed Profiles are seemingly refined as well, as they seem much more fixed on how fast they will travel and how aggressive they will be with things like passing cars on freeways and lane changes.

In future updates, Tesla plans to add Parking Spot selection, along with overall operational improvements. However, CEO Elon Musk recently said that the next branch, Full Self-Driving v14.3, will be where the “final piece of the puzzle is placed.” Tesla believes it is close to solving autonomy, so v14.3 could be a major jump forward, but it remains to be seen.

Tesla adjusts crucial feature as winter weather arrives

Tesla has adjusted the functionality of a crucial climate feature as Winter weather has started to arrive throughout some parts of the United States. The new feature was highly requested by owners.

Tesla has a Cabin Overheat Protection feature that helps keep the temperature regulated if it reaches a certain threshold. Inversely, it can be used in cold weather as well, which will automatically warm the cabin if it sinks to a temperature that is too low for the owner’s comfort.

This is a great way to keep the cabin either warmed up just enough or cooled down just enough so that it never gets too hot or too cold. Extreme temperatures could damage certain parts of the vehicle or damage personal belongings that are kept inside the car.

Overheat protection is a great thing to have in hot climates like Arizona or Texas, especially with the Premium trims of the Model 3 and Model Y, which feature a glass roof.

Many owners appreciate the feature, but they argue that using it at home will utilize too much energy, especially during extreme temperatures. For a while, many Tesla fans have requested an option to disable this feature when the car is parked at home, which the company recently added, according to Not a Tesla App.

The feature is part of Software Version 2025.44.3, and the release notes state:

“You can now choose Exclude Home when Cabin Overheat Protection or No A/C is enabled.”

Tesla has been great at listening to what owners want with new features, and this is one that will reserve some charge and prevent unnecessary utilization of available power, especially as the car is parked at home. If owners want to condition the cabin or get the car ready for operation with a comfortable interior, they can utilize the Tesla app to adjust the climate.
