It’s now clear that SpaceX is preparing to return to the roots of its Starship program with the latest in a series of one-off ‘test tanks’ meant to qualify upgrades to the rocket’s design and production.

Likely known as Starship SN7.2, the hardware will be the first standalone tank built and tested by SpaceX since SN7.1 was successfully pressurized to failure in a process known as burst testing in September 2020. Following in the footsteps of SN7.1, a simple test tank fully focused on qualifying a change in the steel alloy used to build Starships, SN7.2 was somewhat more complex, swapping one of two smooth forward domes with a thrust dome and adding a ‘skirt’ section.

Built out of the same steel alloy as SN7.1, SN7.2 went through similar testing but included the use of a hydraulic ram designed to simulate the thrust of one, two, or three Raptors on the ‘thrust puck’ those engines would otherwise attach to. Starship test tank SN7.2 appears to be quite similar to SN7.1 – but with one or two crucial differences.

The first difference, as noted above, is a reduction in the thickness of the steel rings that make up the outer walls and structure of SN7.2’s barrel-like tank section. SpaceX is believed to have reduced that skin thickness by 25% (4mm to 3mm) in an apparent effort to begin a weight reduction process necessary for Starships to eventually achieve their optimal payload goal of ~150 metric tons (~330,000 lb) to low Earth orbit.

From some angles, SN7.2’s steel rings do appear slightly flimsier or more liable to warp from the heat of welding than other test tanks in the SN7 range, but the differences are rather subtle. Regardless, a reduction from 4mm to 3mm steel rings could likely cut 5-10% from an orbit-capable Starship’s empty weight. When every gram of Starship mass reduction translates directly into an extra gram of payload, it’s safe to say that SpaceX is just getting started.

It’s unclear if a successful SN7.2 test campaign will result in similar reductions to the steel that makes up Starship tank domes and noses. SN7.2’s forward and thrust domes appear to be more or less identical to almost all prior Starship prototype hardware.

Aside from thinner steel skin, it’s also possible that SpaceX will attempt to hit two birds with one stone and test a second unproven change on SN7.2 – namely an upgraded ‘thrust puck’ design. That new puck design first appeared on a November 2020 shipment from SpaceX’s Hawthorne, CA headquarters. Referring to the cone-like structure Starship’s three central Raptor engines attach to and are fed propellant through, the new design simplifies plumbing complexity by allowing Starship’s fuel and fuel header tanks to attach directly to and feed methane through the puck.

SpaceX’s upgraded thrust puck design is likely to debut on Starship SN15 or a fourth SN7 test tank. (NASASpaceflight – bocachicagal)
SN10’s thrust puck appears a bit more complex, although it accomplishes the same task. (NASASpaceflight – bocachicagal)

It’s unclear which thrust puck design SN7.2 has settled on, though SpaceX’s decision to make SN7.2 an engine section test tank arguably points towards the new puck. Regardless, SpaceX will almost certainly install a skirt section – two reinforced rings – underneath SN7.2 once the tank is welded together, giving it the hold-down clamps needed to secure it to a launch mount while simulating Raptor thrust.

Elon Musk reiterates why Tesla will never make an electric motorcycle

Tesla CEO Elon Musk preemptively shut down speculations about a Tesla road bike once more.

Tesla CEO Elon Musk preemptively shut down speculations about a Tesla road bike once more, highlighting that the electric vehicle maker has no plans to enter the electric motorcycle market.  

Musk posted his clarification in a post on X.

Musk’s reply to a fun AI video

X user @Moandbhr posted an AI video featuring the Tesla CEO on the social media platform, captioning it with “Mr. Elon Musk Just Revealed the Game-Changing Tesla Motorcycle.” The short clip depicted Musk approaching a sleek, single-wheeled vehicle, stepping onto it, and gliding off into the distance amid cheers. The fun video received a lot of traction on X, gaining 3.1 million views as of writing. 

Musk replied to the post, stating that a Tesla motorcycle is not going to happen. “Never happening, as we can’t make motorcycles safe. For Community Notes, my near death experience was on a road bike. Dirt bikes are safe if you ride carefully, as you can’t be smashed by a truck,” Musk wrote in his reply. 

Musk’s Past Comments on Two-Wheelers

Musk also detailed his reservations about motorcycles in a December 2019 X post while responding to questions about Tesla’s potential ATV. At the time, he responded positively to an electric ATV, though he also opposed the idea of a Tesla road-going motorcycle. Musk did state that electric dirt bikes might be cool, since they do not operate in areas where large vehicles like Class 8 trucks are present.

“Electric dirt bikes would be cool too. We won’t do road bikes, as too dangerous. I was hit by a truck & almost died on one when I was 17,” Musk wrote in his post. 

Considering Musk’s comments about dirt bikes, however, perhaps Tesla would eventually offer a road bike as a recreational vehicle. Such a two-wheeler would be a good fit for the Cybertruck, as well as future products like the Robovan, which could be converted into an RV.

Tesla continues to build out its workforce for the upcoming Cybercab, with two new job listings for quality inspectors for the autonomous two-seater being listed in the company’s official Careers website. 

Both positions are based in Gigafactory Texas, the site of the Cybercab’s initial production.

New Cybercab listings

Tesla recently added openings for “Quality Inspector, Cybercab” and “Quality Inspector, Cybercab – Incoming Quality” on its Careers website. The roles involve detailed inspections of Cybercab components using precision tools such as calipers, micrometers, and gauges, among others. Candidates must also identify non-conformances, document findings in Tesla’s quality management  system and collaborate with production teams to resolve issues swiftly.

Overall, these new Cybercab-related roles highlight Tesla’s emphasis on precision for the two-seater’s innovative features, such as its inductive charging setup, which is not available on any Tesla consumer vehicle today. If any, the Cybercab’s Quality Inspectors will likely be operating in uncharted territory as the vehicle is being produced using Tesla’s new Unboxed process. Elon Musk has also noted that the Cybercab’s production line will resemble a high-speed consumer electronics line instead of a conventional automotive line.

Recent Cybercab Design Evolutions

Since its October 2024 unveiling, the Cybercab has undergone several refinements visible in recent prototypes, enhancing aerodynamics and manufacturability ahead of production. The tail design now rises slightly for better airflow, with a shortened rear body panel and repositioned red reflectors farther from the wheel arches.

Front-end updates include segmented daytime running lights, actual turn signals and a sharper splitter, while side repeater cameras have shifted forward for improved visibility. Tesla has also enlarged door panels for easier ingress and egress, swapped to unpainted tires without extended covers and adjusted the B-pillar forward and lower, likely to foster a more open cabin feel.
