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 has rolled out a minor update to its Robotaxi service that will likely make the driverless ride-hailing system notably better and more convenient for consumers. The update was confirmed by CEO Elon Musk in a post on social media platform X.

Robotaxi service updates

The Robotaxi update was observed by users of the driverless ride-hailing service over the weekend. As observed by Tesla enthusiast Owen Sparks, the Austin Robotaxi fleet no longer strictly navigates to the pickup point listed on the app. Instead, the Robotaxis now stop in the exact location of a user’s phone.

Elon Musk confirmed the update, noting in a post on X that the change was an upgrade to the service. It’s a reactively minor update in the grand scheme of things, but it should make the Robotaxi service feel more organic and humanlike.

Driverless taxis

Tesla’s Robotaxi service in Austin has been receiving good reviews from users since it was launched, with many praising the vehicles for their cautious and humanlike behavior. Some users on social media even noted that Tesla’s Robotaxis feel safer on the road than cars from services like Uber, which are manually driven.

Tesla’s minor updates to its Robotaxi service are expected to make the customer experience of the driverless ride-hailing service more refined. By doing so, Tesla could ease customers into its service, even if only a fraction of ride-hailing users are familiar with fully autonomous cars. With this in mind, even small updates like picking up customers based on their specific phone location will likely go a long way towards making Tesla’s Robotaxis more accepted by the general public.

Tesla sells 3 million Model 3 since 2017, one in every 1.5 minutes

This translates to one Model 3 being sold every 1.5 minutes on average for the past eight years.

Tesla has announced that the Model 3 sedan has sold 3 million units since it started customer deliveries in 2017. As per the electric vehicle maker, this translates to one Model 3 being sold every 1.5 minutes on average for the past eight years.

Massive Milestone

Tesla China VP Grace Tao announced the Model 3’s milestone on Weibo, highlighting that the all-electric sedan has been a tried and tested vehicle that has earned accolades throughout its tenure. She also highlighted that in a recent test, Car and Driver gave the Model 3 a perfect score. 

“Model 3 has become the choice of more than 3 million car owners worldwide, and has won the global pure electric sedan sales champion for seven consecutive years,” Tao wrote in her Weibo post. 

She also invited everyone to try and test drive the Model 3 sedan, so they could experience the vehicle personally. “Everyone is welcome to come to the store to test drive and experience this global car and champion car,” the Tesla executive added.

Tesla’s Mainstream Bet

There was once a time when Tesla’s future relied on the Model 3’s success. When the Model 3 was unveiled, Tesla was still gaining its footing as a premium automaker that produces the Model S and Model X. The Model 3 was the company’s first mass-market car, and it was Tesla’s first foray into serious mass production. At the time, it was no exaggeration to state that Tesla’s survival depended on the Model 3.

The Model 3’s runaway success was a victory not just for Tesla but for the overall electric vehicle sector as a whole. Because the Model 3 was simply a great car, electric or otherwise, it was able to prove that there is serious demand for reasonably-priced mass market EVs. It was also able to pave the way for the Model Y, Tesla’s mass market all-electric crossover that ultimately became the world’s best-selling car in 2023 and 2024.

Tesla ‘Model Q’ gets bold prediction from Deutsche Bank that investors will love

Tesla’s Model Q could be on the way soon, and a new note from Deutsche Bank thinks it will contribute to Q4 deliveries.

The Tesla “Model Q” has been in the rumor mill for the company for several years, but a recent note from Wall Street firm Deutsche Bank seems to indicate that it could be on its way in the near future.

This comes as Tesla has been indicating for several quarters that its development of affordable models was “on track” for the first half of 2025. The company did not say it would unveil the vehicles in the first half, but many are anticipating that more cost-friendly models could be revealed to the public soon.

Potential affordable Tesla “Model 2/Model Q” test car spotted anew in Giga Texas

The Deutsche Bank note refers to one of the rumored affordable models as the “Model Q,” but we’ve also seen it referred to as the “Model 2,” amongst other names. Tesla has not officially coined any of its upcoming vehicles as such, but these are more of a universally accepted phrase to identify them, at least for now.

The rumors stem from sentiments regarding Tesla’s 2025 delivery projections, which are tempered as the company seeks to maintain a steady pace compared to 2023 and 2024, when it reported 1.8 million deliveries.

Deutsche Bank’s analysts believe the deliveries could be around 1.58 million, but they state this is a cautious stance that could be impacted by several things, including the potential launch of the Model Q, which they believe will make its way to market in Q4:

“Looking at the rest of the year, we maintain a cautious stance on volume calling for 1.58m vehicle deliveries (-12% YoY) vs. consensus +1.62m, with the timing of Model Q rollout as the key swing factor (we now assume only 25k in Q4). In China, Tesla will introduce the Model Y L this fall (6 inch longer wheel base allowing for larger 3-row seating with six seats).”

Interestingly, the same firm also predicted that the Model Q would launch in the first half of the year based on a note that was released in early December 2024.

Those estimations came from a reported meeting that Deutsche Bank had with Tesla late last year, where it said it aimed to launch the Model Q for less than $30,000 and aimed for it to compete with cars like the Volkswagen ID.3 and BYD Dolphin.

Tesla’s Q2 Earnings Call is slated for this Wednesday and could reveal some additional details about the affordable models.
