SpaceX CEO Elon Musk says major Starship engine bug is fixed as Raptor testing continues
SpaceX CEO Elon Musk has revealed the latest official photo of the company’s Raptor engine in action and indicated that a major technical issue with vibration appears to have been solved, hopefully paving the way for Starhopper’s first untethered flights.
Partly due to Musk’s own involvement in the program, SpaceX’s propulsion development team have struggled to get any single Raptor engine to survive more than 50-100 seconds of cumulative test fires. According to information from sources familiar with the program, Musk has enforced an exceptionally hardware-rich development program for the first full-scale Raptor engines to such an extent that several have been destroyed so completely that they could barely be used to inform design optimization work. Although likely more strenuous and inefficient than it needed to be, the exceptionally hardware-rich test program appears to have begun to show fruit, with the sixth engine built (SN06) passing its first tests without exhibiting signs of a problem that has plagued most of the five Raptors that came before it.
Resonance: not even once
In his tweet, Musk cryptically noted that a “600 Hz Raptor vibration problem” appears to have been fixed as of SN06’s first few static fire tests since arriving in McGregor, Texas. More likely than not, the self-taught SpaceX executive is referring to the hell that is mechanical resonance in complex machines and structures. Shown below, the Tacoma Narrows Bridge’s 1940 collapse – quite possibly the single most famous civil engineering failure of all time – is an iconic example of the unintuitive power of resonance in complex systems.
When it was inaugurated, the first Tacoma Narrows Bridge was one of the longest suspension bridges ever built and implemented new techniques and technologies that had never been tried at such a large scale. As Grady (Practical Engineer) aptly notes, mechanical resonance – in this case, triggered by consistent winds running through the Puget Sound – simply wasn’t something that period engineers knew they had to worry about. When rapidly pushing the envelope of engineering and construction, the chances of discovering entirely novel failure modes also increases – it’s simply one of the costs of extreme innovation.
Luckily for SpaceX, the company doesn’t have to clash with the immense challenge of testing something as large, complex, and expensive as a suspension bridge. Raptor, Starship, and Super Heavy need not necessarily be perfect on SpaceX’s first try, whereas civil bridges must essentially be flawless on the first try, despite being one of a kind. This is why SpaceX has been chewing through an average of one Raptor engine per month since February 2019 – by testing engines to destruction and aggressively comparing engineering expectations with observed behavior and post-test hardware conditions, rapid progress can (theoretically) be made.
Instead of spending another year or more analyzing models and testing subscale engines and components, SpaceX dove into integrated testing of a sort of minimum-viable-product Raptor design, accepting that the path to a flightworthy, finalized design would likely be paved with one or several dozen destroyed engines. According to Musk, the biggest pressing design deficiency involved a mode of mechanical resonance that may or may not have been predicted over the course of the design process. Dealing with unprecedented conditions, it’s not particularly surprising that some sort of new resonance mode was discovered in Raptor.
For the time being, SpaceX continues to work around the clock to build its first two orbital Starship prototypes (one in Texas, one in Florida), while also outfitting Starhopper and completing any possible engine-less tests in anticipation of the first flightworthy Raptor’s arrival. If Musk’s early analysis proves correct and Raptor SN06 makes it through lengthier static fire tests unscathed over the next week or so, the engine could potentially be delivered to Boca Chica as early as mid-July.

Tesla begins expanding Robotaxi access: here’s how you can ride
You can ride in a Tesla Robotaxi by heading to its website and filling out the interest form. The company is hand-picking some of those who have done this to gain access to the fleet.

Tesla has begun expanding Robotaxi access beyond the initial small group it offered rides to in late June, as it launched the driverless platform in Austin, Texas.
The small group of people enjoying the Robotaxi ride-hailing service is now growing, as several Austin-area residents are receiving invitations to test out the platform for themselves.
The first rides took place on June 22, and despite a very small number of very manageable and expected hiccups, Tesla Robotaxi was widely successful with its launch.

However, Tesla is expanding the availability of the ride-hailing service to those living in Austin and its surrounding areas, hoping to gather more data and provide access to those who will utilize it on a daily basis.
Many of the people Tesla initially invited, including us, are not local to the Austin area.
There are a handful of people who are, but Tesla was evidently looking for more stable data collection, as many of those early invitees headed back to where they live.
The first handful of invitations in the second round of the Robotaxi platform’s Early Access Program are heading out to Austin locals:

Tesla likely saw an influx of data during the first week, as many traveled far and wide to say they were among the first to test the Robotaxi platform.
Now that the first week and a half of testing is over, Tesla is expanding invites to others. Many of those who have been chosen to gain access to the Robotaxi app and the ride-hailing service state that they simply filled out the interest form on the Robotaxi page of Tesla’s website.
That’s the easiest way you will also gain access, so be sure to fill out that form if you have any interest in riding in Robotaxi.
Tesla will continue to utilize data accumulated from these rides to enable more progress, and eventually, it will lead to even more people being able to hail rides from the driverless platform.
With more success, Tesla will start to phase out some of the Safety Monitors and Supervisors it is using to ensure things run smoothly. CEO Elon Musk said Tesla could start increasing the number of Robotaxis to monitors within the next couple of months.

Tesla analyst issues stern warning to investors: forget Trump-Musk feud

A Tesla analyst today said that investors should not lose sight of what is truly important in the grand scheme of being a shareholder, and that any near-term drama between CEO Elon Musk and U.S. President Donald Trump should not outshine the progress made by the company.
Gene Munster of Deepwater Management said that Tesla’s progress in autonomy is a much larger influence and a significantly bigger part of the company’s story than any disagreement between political policies.
Munster appeared on CNBC‘s “Closing Bell” yesterday to reiterate this point:
“One thing that is critical for Tesla investors to remember is that what’s going on with the business, with autonomy, the progress that they’re making, albeit early, is much bigger than any feud that is going to happen week-to-week between the President and Elon. So, I understand the reaction, but ultimately, I think that cooler heads will prevail. If they don’t, autonomy is still coming, one way or the other.”

This is a point that other analysts like Dan Ives of Wedbush and Cathie Wood of ARK Invest also made yesterday.
On two occasions over the past month, Musk and President Trump have gotten involved in a very public disagreement over the “Big Beautiful Bill,” which officially passed through the Senate yesterday and is making its way to the House of Representatives.
Musk is upset with the spending in the bill, while President Trump continues to reiterate that the Tesla CEO is only frustrated with the removal of an “EV mandate,” which does not exist federally, nor is it something Musk has expressed any frustration with.
In fact, Musk has pushed back against keeping federal subsidies for EVs, as long as gas and oil subsidies are also removed.
Nevertheless, Ives and Wood both said yesterday that they believe the political hardship between Musk and President Trump will pass because both realize the world is a better place with them on the same team.
Munster’s perspective is that, even though Musk’s feud with President Trump could apply near-term pressure to the stock, the company’s progress in autonomy is an indication that, in the long term, Tesla is set up to succeed.
Tesla launched its Robotaxi platform in Austin on June 22 and is expanding access to more members of the public. Austin residents are now reporting that they have been invited to join the program.

Tesla surges following better-than-expected delivery report
Tesla saw some positive momentum during trading hours as it reported its deliveries for Q2.

Tesla (NASDAQ: TSLA) surged over four percent on Wednesday morning after the company reported better-than-expected deliveries. It was nearly right on consensus estimations, as Wall Street predicted the company would deliver 385,000 cars in Q2.
Tesla reported that it delivered 384,122 vehicles in Q2. Many, including those inside the Tesla community, were anticipating deliveries in the 340,000 to 360,000 range, while Wall Street seemed to get it just right.

Despite Tesla meeting consensus estimations, there were real concerns about what the company would report for Q2.
There were reportedly brief pauses in production at Gigafactory Texas during the quarter and the ramp of the new Model Y configuration across the globe were expected to provide headwinds for the EV maker during the quarter.
At noon on the East Coast, Tesla shares were up about 4.5 percent.
It is expected that Tesla will likely equal the number of deliveries it completed in both of the past two years.
It has hovered at the 1.8 million mark since 2023, and it seems it is right on pace to match that once again. Early last year, Tesla said that annual growth would be “notably lower” than expected due to its development of a new vehicle platform, which will enable more affordable models to be offered to the public.
These cars are expected to be unveiled at some point this year, as Tesla said they were “on track” to be produced in the first half of the year. Tesla has yet to unveil these vehicle designs to the public.
Dan Ives of Wedbush said in a note to investors this morning that the company’s rebound in China in June reflects good things to come, especially given the Model Y and its ramp across the world.
He also said that Musk’s commitment to the company and return from politics played a major role in the company’s performance in Q2:
“If Musk continues to lead and remain in the driver’s seat, we believe Tesla is on a path to an accelerated growth path over the coming years with deliveries expected to ramp in the back-half of 2025 following the Model Y refresh cycle.”
Ives maintained his $500 price target and the ‘Outperform’ rating he held on the stock:
“Tesla’s future is in many ways the brightest it’s ever been in our view given autonomous, FSD, robotics, and many other technology innovations now on the horizon with 90% of the valuation being driven by autonomous and robotics over the coming years but Musk needs to focus on driving Tesla and not putting his political views first. We maintain our OUTPERFORM and $500 PT.”
Moving forward, investors will look to see some gradual growth over the next few quarters. At worst, Tesla should look to match 2023 and 2024 full-year delivery figures, which could be beaten if the automaker can offer those affordable models by the end of the year.
