SpaceX begins building upgraded Starship prototype
A Starship part spotted on July 20th confirms that SpaceX is already well into the process of building a significantly upgraded full-scale prototype.
Following in the footsteps of five or six full-scale ships before it, information published by NASASpaceflight.com suggests that Starship SN8 will be a substantial departure from its predecessors. Thanks to data gathered by testing the Starship SN7 test tank to destruction on June 24th, SpaceX has determined that a different alloy – known as 304L – is superior to the 301 stainless steel all Starship prototypes have been built out of up to now.
SN8 is SpaceX’s response to that discovery. As usual, the company has performed smaller tests before deciding to build a full-scale Starship prototype – identical to all previous SNx prototypes beyond the alloy change – out of 304L stainless steel. As a result, Starship SN8 – once complete – may have the most potential of any prototype built thus far, but its fate will also be more uncertain than most of its predecessors.
On June 24th, SpaceX destroyed the SN7 Starship test tank as part of a controlled cryogenic proof test – essentially a pressure test at cryogenic (ultra-cold) temperatures. Departing from routine, CEO Elon Musk never commented on the test, leaving its results shrouded in mystery. According to NASASpaceflight, however, SN7 “achieved a record pressure before it failed.”
Designed to test a different formulation of stainless steel, that success implies that SN7 proved that the 304L alloy will not only be more malleable and forgiving at cryogenic temperatures – but is also more capable overall compared to 301 steel. To beat the record set by the second or third Starship test tank in January or March 2020, SN7 would have had to reach pressures of ~8.6 bar or higher – effectively icing on the cake for the already-demonstrated ~140% safety factor.
A full-scale Starship has yet to survive proof tests at those pressures but Starship SN4 did become the first to complete a full cryo proof, sustaining ~7.5 bar (~110 psi) before it was safely depressurized. Currently on the pad and preparing for an imminent static fire and hop test debut, Starship SN5 is unlikely to put pressure on that record unless that it aces both of the aforementioned trials. Built entirely out of the 304L alloy already proven to be superior to 301, SN8 may well be the golden goose of prototypes.
“The vehicle will feature major upgrades over previous Starship prototypes. SN8 will be built out of 304L stainless steel versus 301 and will receive a fairing, aerosurfaces, and three Raptor engines to allow for a higher-altitude test flight.”

The appearance of SN8’s labeled common dome – the dome separating Starship’s liquid oxygen and methane tanks – implies that a variety of other parts spotted over the last few days are also meant for the next full-scale rocket. Mounted on a stand purpose-built for the task, the SN8 common dome will soon be ‘sleeved’ by one or several stacked steel rings, after which it can be welded to the rest of the Starship’s tank. An engine section and thrust structure – likely SN8’s – in the late stages of assembly was spotted three days prior, while an upper tank dome that could be for either SN8 or test tank SN7.1 was captured in the same photos.
In the last photo, taken on July 13th, there’s even signs of what could be Starship SN9 – hinted at by the appearance of two Starship engine sections signified by the pattern of welds on their exteriors. Those welds are incontrovertible signs of the stringers used to strengthen Starship engine sections and they haven’t been used anywhere else on past prototypes.
Based on the sheer number of steel rings and domes currently floating around SpaceX’s Boca Chica, Texas Starship factory, SN8 could be a just a week – or even less – away from final stacking operations. If SN5 leaves the pad intact and completes its wet dress rehearsal, static fire, and flight debut without issue, SN8 could be up to bat much sooner than later.

Tesla launched the all-electric, steering wheel-less, and pedal-less Cybercab last night at a quiet and small event in downtown Austin, Texas.
The launch, which marked the beginning of unsupervised ride-hailing for Tesla’s Robotaxi platform with Cybercab, has already caught the attention of the National Highway Traffic Safety Administration (NHTSA) who has more questions.
NHTSA opened an Audit Query (AQ) into the Cybercab’s Federal Motor Vehicle Safety Standards (FMVSS) certification that Tesla gave the vehicle. Manufacturers self-certify vehicles much of the time to avoid excessive regulatory delays.

However, the agency needs more information; it said in a summary:
“On September 3, 2026, Tesla began commercial deployment with a small number of its Cybercab vehicles in Austin, Texas. Tesla notified the Agency that it certified those Cybercab vehicles as compliant with all applicable Federal Motor Vehicle Safety Standards (FMVSS). Tesla also notified the Agency that it plans to gradually expand commercial deployment of the Cybercab to include additional vehicles and locations.”
It also went on to state that the Cybercab lacks traditional automotive controls, which is a groundbreaking move. The process is entirely new to the NHTSA, which gives the agency some leverage to put Tesla’s launch under a microscope:
“The vehicles lack permanently attached, conventional manual controls, such as a brake pedal, gas pedal, steering wheel, and mirrors. NHTSA is opening this AQ to examine the process and technical data on which Tesla relied when certifying the Cybercab and related issues. Among other things, NHTSA will consider the extent to which Tesla’s certification depended on determinations that certain FMVSS are inapplicable to the Cybercab.”
Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents the company submitted to the State of Texas over the past week. Enabling this level of self-driving is something Tesla has worked toward for many years, and now that it is finally here, it seems more than reasonable that regulatory agencies will have some questions.
Many outlets might try to frame this as a negative, but it is truly an agency looking to gain more information about groundbreaking tech that Tesla has been developing for years.
In an effort to keep riders, pedestrians, and property safe, any and all data accumulated from these first days, weeks, and months of rides will likely be shared with the NHTSA to enable broader rollout strategies across the United States and more in the future.

Tesla Cybercab is coming to Asia this month as US service officially begins
Tesla Asia says Cybercab will be on display in Hong Kong, Tokyo, Beijing and Shanghai this month.
Tesla’s Cybercab is heading to Asia. The official Tesla Asia account posted on X Thursday, inviting Cybercab fans to “Come experience the future of autonomy in Hong Kong, Tokyo, Beijing & Shanghai.” The post went up within hours of Tesla’s own Cybercab milestone in Texas, where the company said Thursday it had begun offering rides in across Austin.
Exact dates and venues for the Asia tour haven’t been released yet, though Tesla Hong Kong replied to the announcement with “Cybercab will be on display in Hong Kong soon,” while Tesla Japan’s response pointed fans to a sign up page for updates. Neither post mentions test rides or a service area, and nothing so far suggests Tesla is launching Robotaxi operations in any of the four cities. Based on how Tesla has run past Cybercab tours, in Europe in late 2024 and at US shopping centers that same December, the Asia stops are almost certainly static displays at Tesla stores or public venues as a means to stimulate buzz for its future driverless ride-hailing service in the big cities.

The timing lines up with Tesla’s only prior Cybercab appearance in the region, a booth at the China International Import Expo in Shanghai last November, which Teslarati covered at the time. At that event, Tesla’s regional general manager for Shanghai framed the car as evidence of the company’s broader mission, a message Tesla has since formalized in its Master Plan Part IV, which states that “autonomous vehicles have the capacity to dramatically improve the affordability, availability and safety of transportation while reducing pollution, particularly in our increasingly dense global cities.” The same document is where Tesla lays out its “sustainable abundance” framing for Cybercab and Optimus alike, describing the two as the hardware behind an AI driven push to cut the cost of transportation and labor at scale.
Whether Cybercab actually operates as a robotaxi anywhere in Asia remains an open question, considering China has already pushed an autonomous ride-hailing market that’s run on homegrown players like Baidu’s Apollo Go and Pony AI. For now, the four city tour reads as a marketing push timed to Austin’s momentum.

Tesla Cybertruck targets job site crews with new Tailgate Utility Track and Bed Gear Box accessory
Tesla launched a $350 tailgate track and a $985 lockable Bed Gear Box for Cybertruck.
Tesla’s Cybertruck team added two more items to the Tesla Shop, targeting job site crews and owners who use the truck bed for actual work rather than just showing it off. The official Cybertruck X account posted the Tailgate Utility Track and the Bed Gear Box within minutes of each other, part of a five item batch that also included a reflective jacket, a spray paint hat and an updated reflective tee.
The Tailgate Utility Track runs $350 and turns the folded down tailgate into another mounting surface. It’s a single aluminum track with a T-slot for sliding accessories and two L-track attachment points, plus two load stops included in the box. The pitch is straightforward: strap down oversized cargo, like lumber or a cooler, that hangs off the back of the bed without it sliding out mid-drive. It bolts onto the existing tailgate and works on every Cybertruck trim.

The Bed Gear Box costs $985 and is a different kind of accessory. It’s a lockable aluminum storage box, 55.78 inches long, 19.8 inches wide and 7.79 inches tall, that mounts to the bed’s L-track rails and comes with two internal bins for smaller items. According to Tesla, at just over 57 pounds empty, it’s meant to stay in place rather than come in and out with each trip, giving owners a factory-fit alternative to loose totes for tools, recovery gear or emergency supplies. Tesla’s listing notes that Long Range and Dual Motor AWD Cybertrucks need the L-Tracks accessory installed separately before the Gear Box will mount, since L-tracks come standard only on certain configurations.

Both accessories lean on the idea Tesla has been building toward since Elon Musk first described the Cybertruck’s third-party attachment strategy at the 2023 shareholder meeting, when he said the truck would ship with mounting points so outside companies, and Tesla itself, could keep adding gear without redesigning the bed. That’s the same L-track backbone underneath the tailgate shield and jumpseats Tesla launched last year, and the off-road armor package that arrived through the same X account in 2025.
Owners looking to round out the rest of the L-track ecosystem, cargo dividers, MOLLE panels, bed racks and similar gear, can find a wider range of options through our Cybertruck accessories collection.
