For the fourth time ever, SpaceX is ready to destroy a Starship test tank – the results of which will \determine the next steps for Starship development.

Technically, this will be the second time SpaceX has attempted to destroy Starship test tank SN7.1 following an unsuccessful night of testing on September 17th. Following two days of back-to-back stress tests on the 14th and 15th, successfully proving that SpaceX’s newest test tank and steel alloy can withstand the rigors of suborbital launch, unknown issues scrubbed a third series of tests meant to intentionally destroy SN7.1.

Excluding Starship SN2, thus far the only test tank to survive, SpaceX’s latest intentionally destructive test campaign builds on the controlled failures of two unnamed tanks in January and Starship SN7 in June. SN7.1 is essentially a more complex version of SN7, integrating a “thrust puck” to ensure that SpaceX’s custom steel alloy is also the right choice for the puck-like structure tasked with transferring the thrust of 3-6 Raptor engines through the rest of Starship.

Theoretically, the 304L-esque alloy SpaceX has decided to replace 301 steel with should make Starships less brittle under cryogenic temperatures, meaning that a breached tank should spring leaks instead of violently bursting. That characteristic would be a boon for vehicle safety and survivability relative to almost any other rocket. With Starship test tank SN7, SpaceX has already demonstrated that its custom steel alloy will gently leak before bursting.

Simultaneously, SN7 is believed to have broken SpaceX’s internal Starship tank pressure record despite having multiple flawed welds, meaning that SN7.1 could reach even higher pressures if SpaceX has since improved build quality.

Ironically built well before test tank SN7.1, SpaceX has already completed the tank section of SN8 – the first full-size Starship to exclusively use the company’s custom steel alloy. Given that SN7.1 has already survived two full nights of nondestructive tests, it’s safe to say that SpaceX is likely happy with the tank’s performance and that the viability of 304L steel has been thoroughly vetted. In the unlikely event that any unsavory discoveries are made in the process of destroying test tank SN7.1, that might change, but the purpose of destructive tank testing is less to qualify new designs than it is to push the more abstract limits of materials and manufacturing techniques.

As previously discussed on Teslarati, it remains to be seen if SpaceX will begin testing Starship SN8 before the prototype has been fully outfitted with a nosecone, plumbed header tanks, and four flaps. If SpaceX does choose to test SN8 prior to completion, the prototype could be ready to head to the launch pad almost as soon as SN7.1 is destroyed.

SN7.1’s final test window stretches from 9pm to 6am CDT (UTC-5) on September 21st with an identical backup on the 22nd. The test will be streamed by NASASpaceflight (until SN7.1 has burst or the window has closed) and LabPadre (a 24/7 feed).

The first look at the Tesla Cybertruck police cruisers for the Las Vegas Metro Police Department has been going around as the city begins to add them to its active fleet.

The LVMPD released a new video of the police cruisers that were donated by billionaires Ben and Felicia Horowitz, showing their design, as well as the first look at the front of the vehicle where police will sit, as well as the back where the criminals will think about their actions.

Sheriff Kevin McMahill commented on the addition of the Cybertrucks to the fleet, which includes recognition of their symbolism regarding the mission of the Department itself:

“These represent something bigger than a police vehicle. They represent innovation and our continued commitment to serve this community with the best tools available — safely, efficiently, and responsibly. They can handle everything from Fremont Street to Red Rock Canyon.”

The LVMPD had the Cybertrucks primed for law enforcement use by Upfit Tesla, a division of Unplugged Performance, the unequivocal leader in performance upgrades for Teslas.

The first look at the interior of the police cruisers is awesome to see, especially as it shows the Cybertruck’s ability to cater to every and any application for personal or professional use.

The front of the Cybertruck police vehicle shows an interior fully outfitted for a shift in Las Vegas. A laptop is mounted next to the center touchscreen, and siren and light controls are located in the center for easy access for officers:

The rear of the cruiser is plain and fitted with plastic seats, typical for the transportation of criminals and suspects, as well as a partition that appears to be made of ballistic glass, helping to protect officers from those they have arrested. It is also reinforced with steel and foam lines the top of the partition:

The fleet was donated shortly after a Cybertruck exploded at the front entrance of Trump Tower in Las Vegas in January. While the person inside lost their life, the Cybertruck’s ability to muffle most of the blast and keep damage relatively limited to the building impressed many.

The Tesla Cybercab has been spotted testing on public roads for the first time, marking a substantial step forward in the vehicle’s development.

The car was spotted just minutes from Tesla’s Engineering Headquarters in Los Altos, California. There are a few interesting tidbits we can gather from the photo and the information shared with it:

The vehicle had a driver and side view mirrors equipped on it, which seems to be pretty expected, especially at this stage.

Tesla might have been using its Full Self-Driving software with the vehicle as it enters this new stage of testing on public roads. This seems most likely, especially as the car, which has long been developed to be void of a steering wheel and pedals, will totally rely on autonomous tech to transport one or two passengers to their destination.

Additionally, side view mirrors are required by law at delivery, and Tesla was likely looking to keep things as safe and elementary as possible, especially with this early stage of testing.

As this is the first time the vehicle has been spotted on public roads and the first time it was likely testing on them, Tesla was being cautious.

There have been a lot of developments with Cybercab over the past few weeks, as the car has been spotted testing on the Fremont Factory’s test track, units have been seen outside of Gigafactory Texas’s crash testing facility, and there has been some additional speculation about what the vehicle’s standard equipment will be.

There have also been quite a few job postings by Tesla for manufacturing and production roles related to Cybercab over the past few weeks.

Yesterday, Tesla’s Board Chair, Robyn Denholm, revealed that the company could end up building Cybercab with a steering wheel and pedals, contrary to what Tesla and CEO Elon Musk have wanted to do.

Tesla Cybercab might be getting a huge change

The vehicle has yet to reach that stage of regulatory testing, but Tesla wants to start volume production in Q2. If it wants to release the vehicle without any manual controls, that means that Full Self-Driving will need to be completed within the next eight months.

Tesla hints it could see ‘a few more vehicles’ released soon

Denholm said on CNBC yesterday that “we do have a few other vehicles coming out.”

Published

Tesla Board Chair Robyn Denholm hinted the company could see “a few more vehicles” coming out and being released soon, although there is no indication of what could be on the way based on her comments.

However, Tesla has hinted toward several potential releases in the coming years, as other executives, including Chief Designer Franz von Holzhausen, have talked briefly about what could be on the way.

Denholm said on CNBC yesterday that “we do have a few other vehicles coming out.”

It was a vague and almost cryptic sentence, as, in all honesty, it was not completely clear whether she was talking about recent releases that are just making their way to market, like the Model 3 and Model Y “Standard,” or new vehicles altogether.

Nevertheless, it’s worth dissecting.

Tesla “Standard” Models

On October 7, Tesla launched the Standard Model 3 and Model Y, stripped-down versions of their now “Premium” siblings. The Standard trims lack premium features like leather seats, a rear touchscreen, and a glass roof, among other features.

Tesla begins deliveries of its affordable Model Y Standard

These cars are just starting to be delivered for the first time, so it is possible that Denholm was referring to these cars.

Potential Model 2 Hint?

There has always been a looming vehicle model that many Tesla fans and owners have been intrigued by: the Model 2.

This car was hinted at being the $25,000 model that Tesla was rumored to be developing, and many thought that was the vehicle that would be released earlier this month, not the Standard Model 3 and Model Y.

Instead, the Model 2 could be something that would enable Tesla to reach an entirely new consumer base, including those who are not able to swing the payment for the company’s more premium offerings.

It seems Tesla will have to launch some sort of extremely affordable model in the future, and with the Cybercab being slotted at that rough price point, it would not be out of the question for it to be in the realm of possibility for future releases.

It’s worth noting, however, that it is probably unlikely this will happen. Tesla is so deadset focused on autonomy, it seems Cybercab would take extreme precedence over the unconfirmed “Model 2.”

Cybertruck-inspired SUV

Tesla fans have been begging the company to develop a full-size SUV that would compete with the Ford Expedition or Chevrolet Tahoe, but the company has not given any indication that this would be something it would build.

Nevertheless, there was a very subtle hint in a recent promotional clip that showed a Cyber SUV mock-up placed strategically next to a clay model of a Model 3:

Tesla appears to be mulling a Cyber SUV design

The Model X is simply not what people want when it comes to an SUV, as it does not have the seating capacity and cargo space that many need with a full-sized SUV.

This issue, in particular, has been one that has been extremely relevant to the company’s future lineup as consumers have shown they would be interested in a Tesla vehicle that fit this description.

Additionally, von Holzhausen said in September that a Cyber SUV or a smaller electric pickup with a more traditional design is “definitely things we’ve considered…We’re working on so many innovative and fun things.”
