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.

Trump’s auto tariffs spark concerns in Japan

Japan expressed concern over President Trump’s auto tariffs, citing inconsistencies with a 2019 bilateral trade deal signed with the U.S.

Prime Minister Shigeru Ishiba said Japan is committed to the 2019 agreement despite current concerns over President Trump’s new tariffs.

Trump’s tariffs impose a 25% duty on imported vehicles, effective April 3, 2025, and auto parts duties will be imposed in May. The 2019 U.S.-Japan trade deal, signed during Trump’s first term, reduced tariffs on U.S. farm goods and Japanese machine tools.

Then-Prime Minister Shinzo Abe secured assurances from Trump, stating, “Between President Trump and I, this has been firmly confirmed that no further, additional tariffs will imposed.”

The 2019 bilateral trade deal did not cover auto trade between the United States and Japan. However, at the time, Prime Minister Abe had received assurances from President Trump that the U.S. would not impose national security tariffs on Japanese car imports. As such, the deal avoided higher U.S. car duties.

According to Reuters, Japan faces Trump’s 24% tariff on its exports to the United States, which were paused until July. Trump’s 25% auto tariff and a 10% universal rate remain intact, impacting Japan’s car-heavy economy.

Ishiba addressed the issue in parliament, noting, “Japan has grave concern over the consistency” between the tariffs and the 2019 bilateral deal. “We will continue to convey our stance (to the U.S.) from this standpoint,” he added, clarifying that Japan has no plans to terminate the agreement. The deal excluded automobile trade and remains a cornerstone of bilateral relations.

Japan’s trade negotiator, Ryosei Akazawa, visited Washington last week to discuss trade issues, including non-tariff barriers and exchange rates. Finance Minister Katsunobu Kato is set to meet U.S. Treasury Secretary Scott Bessent this week to address currency concerns, signaling Japan’s proactive diplomacy.

Japan’s firm stance reflects its intent to protect its auto sector while navigating U.S. trade policies. As talks continue, the outcome could shape bilateral trade dynamics and influence Japan’s export strategy amid ongoing tariff uncertainties.

Elon Musk dubs lawsuit alleging false Tesla odometer readings “idiotic”

The lawsuit alleged that Tesla’s odometer readings use “predictive algorithms” instead of actual mileage driven.

Elon Musk has responded sharply to a lawsuit alleging that Tesla speeds up its vehicles’ odometers to avoid paying for warranty-covered repairs. 

Musk’s comment about the lawsuit’s allegations were posted on social media platform X.

The Lawsuit’s Allegations

The proposed class-action lawsuit claimed that Tesla is speeding up its vehicles’ odometers so that they can fall out of warranty quicker. This system, the lawsuit alleged, allows Tesla to save a significant amount of money in repairs.

The lawsuit’s plaintiff is Los Angeles resident Nyree Hinton, who alleged that his 2020 Tesla Model Y’s odometer readings reflect energy consumption, driver behavior and “predictive algorithms” instead of actual mileage driven, as noted in a Reuters report. 

Hinton claimed that based on other vehicles and driving history, his car was stating that he was driving 72 miles a day when he usually drove just 20 miles at most. Because of this, Hinton alleged that his basic warranty expired well ahead of schedule, resulting in him paying $10,000 for a suspension repair that he believes should have been covered by warranty.

“By tying warranty limits and lease mileage caps to inflated ‘odometer’ readings, Tesla increases repair revenue, reduces warranty obligations, and compels consumers to purchase extended warranties prematurely,” the lawsuit noted.

Elon Musk’s Response

Tesla and its legal team have fully denied all material allegations that were outlined in the proposed class-action lawsuit. In a comment to longtime FSD user @WholeMarsBlog on X, Tesla CEO Elon Musk also criticized the proposed class-action lawsuit. “This is idiotic,” the CEO wrote in a post on X.

Veteran EV owners have also stated on social media that the lawsuit’s claims were inaccurate since Tesla’s odometers do not, in any way, use predictive algorithms. Others also pointed out that repairs are not a major source of profit for Teslas because the company’s vehicles tend to last long without requiring maintenance or spare parts.

A man who attacked a Tesla Cybertruck in South Korea’s Gangnam district has been arrested and detained.

As per reports, the man is also accused of assaulting a person and damaging several other vehicles during the incident.

The Incident

As per authorities, the suspect, who is in his 30s and is dubbed “Mr. A” (suspect names are typically not disclosed in South Korea to protect privacy and prevent possible prejudice), allegedly assaulted a hotel employee on the morning of April 15. 

Following the assault on the hotel employee, the suspect reportedly knocked over a delivery motorcycle. He then went over and kicked a Tesla Cybertruck that was owned by a nearby medical facility. One of the all-electric truck’s side mirrors was damaged due to the attack. 

As per a News 1 Korea report, Mr. A has also been accused of kicking four BMW vehicles at a nearby auto shop. The BMWs’ passenger side doors were damaged by the suspect.

Charges and Arrest

As per the Seoul Gangnam Police Station in an announcement, an investigation into the incident is underway. The suspect was arrested on charges of special assault, property damage, and obstruction of business.

Authorities apprehended Mr. A in Seongnam, Gyeonggi Province, on April 18. An arrest warrant from the court was released the day after.

Cybertruck Attacks

The Tesla Cybertruck attack in South Korea is quite bizarre as the suspect assaulted both people and vehicles. The incident, if any, seems to be quite different from the attacks on Teslas that have been reported in the United States and Europe, which seemed to be political in nature and a response to CEO Elon Musk’s close relationship with President Donald Trump.
