SpaceX appears to have successfully fired up its fourth full-scale Starship prototype for the third time, although the Raptor engine test ended with the aft end of the ship catching fire and burning for quite some time.

Around May 7th, hours after Starship SN4 completed its second wet dress rehearsal and Raptor static fire in ~24 hours, SpaceX removed the SN18 Raptor engine it had used to support those tests, transporting it back to storage facilities a mile down the road. Three days later, SpaceX sent Raptor SN20 down the same same road and installed it on Starship SN4 – a swap made for unknown reasons.

Regardless, that swap meant that SpaceX would need to perform at least one more static fire test to prove that Starship and its new Raptor engine were getting along before the company could proceed to hop test preparations. After several days of at least 4 aborted Starship static fire attempts, SpaceX has finally managed to fuel Starship SN4 and ignite Raptor engine SN20 – but not before a new challenge cropped up.

Just shy of 1:01 pm CDT (18:01 UTC), Starship SN4 appeared to successfully fire up Raptor SN20 for at least several seconds, serving as an in-situ acceptance test for the advanced rocket engine. Like the Merlin 1D engines that power Falcon 9 boosters, Raptors are built in Hawthorne, California, shipped to McGregor, Texas for standalone acceptance testing, installed on their assigned rocket, and static fired one more time before SpaceX deems them ready for launch.

This static fire thus served to verify that Starship SN4 and Raptor SN20 were both still in good health after a busy week of numerous tests and several weeks or months in storage, respectively. If fully successful, it would likely clear Starship SN4 to attempt what would be the inaugural flight of a full-scale Starship prototype, potentially ready to occur as early as May 21st (pending an FAA license, of course). Unfortunately, when Raptor SN20 ignited, it appeared to shake or overpressurize one or several plumbing lines, catching what must have been a methane vent or drain line on fire.

While the rocket itself is likely totally fine, much like its Starhopper predecessor suffered even worse fires during its summer 2019 test campaign, the dark smoke that appeared shortly after the secondary fire started is not a great sign. As methane and oxygen burn quite cleanly, that smoke likely means that the fire(s) got to some of the extensive wiring covering Starship and connecting to its test stand and ground controllers. If damaged, all of that wiring will need to be replaced, while the leaky methane pipe that burned for a solid 15 minutes will also need to be fixed.

As such, it’s likely that Starship SN4 will need to wait at least several more days – and may even need to complete a fourth static fire test – before SpaceX can clear it for an inaugural 150m (~500 ft) hop test.

This signature Tesla feature is facing a ban in one of its biggest markets

The report indicates that Chinese government agencies have concerns “about failure rates and safety issues with the flush design.”

A signature Tesla feature is under fire in one of the company’s largest markets, as regulators in one EV hot spot are mulling the potential ban of a design the automaker implemented on some of its vehicles.

Tesla pioneered the pop-out door handle on its Model S back in 2012, and CEO Elon Musk felt the self-presenting design was a great way to feel like “you’re part of the future.”

It is something that is still present on current Model S designs, while other vehicles in the Tesla lineup have a variety of handle aesthetics.

According to Chinese media outlet Mingjing Pro, the company, along with others using similar technology, is facing scrutiny on the design as regulators consider a ban on the mechanism. These restrictions would impact other companies that have utilized pop-out handles on their own designs; Tesla would not be the only company forced to make changes.

The report indicates that Chinese government agencies have concerns “about failure rates and safety issues with the flush design.”

However, EVs are designed to be as aerodynamically efficient as possible, which is the main reason for this design. It is also the reason that many EVs utilize wheel covers, and sleek and flowing shapes.

However, the Chinese government is not convinced, as they stated the aerodynamic improvements are “minimal,” and safety issues are “significantly elevated,” according to The Independent.

The issue also seems to be focused on how effective the handle design is. According to data, one EV manufacturer, which was not specified in the report, has 12 percent of its total repairs are door handle failure fixes.

There are also concerns about the handles short-circuiting, leaving passengers trapped within cars. Tesla has implemented emergency latch releases in its vehicles that would prevent passengers from getting stuck in their cars in cases of electric malfunctions or failures.

However, evidence from the Chinese Insurance Automotive Technology Research Institute (C-IASI) suggests that 33 percent of door handles using this design fail to function after a side impact.

Obviously, Tesla and other automakers could introduce an alternative design to those vehicles that are affected by the potential restrictions China intends to impose. The regulation would take effect in July 2027.

Tesla is bailing out Canadian automakers once again: here’s how

Tesla is bailing out Canadian automakers once again, as some companies in the country are consistently failing to reach mandated minimum sales targets for emission-free vehicles.

Many countries and regions across the world have enacted mandates that require car companies to sell a certain percentage of electric powertrains each year in an effort to make sustainable transportation more popular.

These mandates are specifically to help reduce the environmental impacts of gas-powered cars. In Canada, 20 percent of new car sales in the 2026 model year must be of an emissions-free powertrain. This number will eventually increase to 100 percent of sales by 2030, or else automakers will pay a substantial fine — $20,000 per vehicle.

There is a way companies can avoid fines, and it involves purchasing credits from companies that have a surplus of emissions-free sales.

Tesla is the only company with this surplus, so it will be bailing out a significant number of other automakers that have fallen short of reaching their emissions targets.

Brian Kingston, CEO of the Canadian Vehicle Manufacturers’ Association, said (via Yahoo):

“The only manufacturer that would have a surplus of credits is Tesla, because all they do is sell electric vehicles. A manufacturer has to enter into an agreement with them to purchase credits to help them meet the mandate.”

Tesla has made just over $1 billion this year alone in automotive regulatory credits, which is revenue acquired from selling these to lagging car companies. Kingstone believes Tesla could be looking at roughly $3 billion in credit purchases to comply with the global regulations.

Automakers operating in Canada are not putting in a lack of effort, but their slow pace in gaining traction in the EV space is a more relevant issue. Execution is where these companies are falling short, and Tesla is a beneficiary of their slow progress.

Kingston doesn’t believe the mandates are necessarily constructive:

“We’ve seen over $40 billion in new investment into Canada since 2020 and all signs were pointing to the automotive industry thriving. Now the federal government has regulations that specifically punishes companies that have a footprint here, requiring them to purchase credits from a company that has a minimal (Canadian) footprint and an almost nonexistent employee base.”

Kingston raises a valid point, but it is hard to see how Tesla is to blame for the issue of other car companies struggling to bring attractive, high-tech, and effective electric powertrains to market.

Tesla has continued to establish itself as the most technologically advanced company in terms of EVs and its tech, as it still offers the best product and has also established the most widespread charging infrastructure globally.

This is not to say other companies do not have good products. In my personal experience, Teslas are just more user-friendly, intuitive, and convenient.

Tesla ditches key Cybertruck charging feature for very obvious reason

“Wireless charging something as far off the ground as the [Cybertruck] is silly.”

Tesla is officially ditching the development of a key Cybertruck charging feature, and the reason is very obvious, all things considered.

The Cybertruck is among the most unique vehicles available on the market, and, like all Tesla vehicles, it has continued to improve through Over-the-Air software updates that enhance performance, safety, and other technological features.

However, the development of some features, while great on paper, turns out to be more difficult than expected. One of these features is the presence of wireless charging on the all-electric pickup, a capability Tesla has been working to integrate across its entire vehicle lineup.

Tesla wireless charging patent revealed ahead of Robotaxi unveiling event

Most people who have used wireless charging for their phones or other devices have realized it is not as effective as plugging into a cord or cable. This is even relevant with Tesla vehicles, as the introduction of wireless charging for smartphones within the vehicles has been a nice feature, but not as impactful as many would hope.

It’s not necessarily Tesla’s fault, either. Wireless charging is a complex technology because much of the energy intended to be transferred to the phone is lost through heat.

Instead of the energy being stored in the battery, it is lost on the outside of the phone, which is why it becomes warm to the touch after sitting on a charging mat.

This is something that Tesla is likely trying to resolve with its vehicles before rolling out inductive charging to owners. The company has confirmed that it is working on a wireless charging solution, but it has yet to be released.

However, this feature will not be coming to the Cybertruck. Wes Morrill, the Cybertruck’s lead engineer, said that the vehicle’s height makes wireless charging “silly,” according to Not a Tesla App:

“Wireless charging something as far off the ground as the CT is silly.”

This is something that could impact future vehicle designs; the Cybertruck might not be the only higher-ground clearance vehicle Tesla plans to offer to customers. Therefore, being transparent about a design’s capabilities, or even developing technology that would enable this, would be useful to potential buyers.

At this point, wireless charging seems like it would be more advantageous for home charging than anything.

Due to its current inefficiency, it would likely be a great way to enable seamless charging in a garage or residential parking space, rather than something like a public charger where people are looking to plug and go in as little time as possible.
