SpaceX’s first high-flying, triple-engine Starship prototype is rapidly approaching completion at the same time as the company is preparing for the rocket’s predecessor to lift off on its inaugural test flight.

Known as serial number 5 (SN5), it will be the fifth full-scale Starship prototype completed by SpaceX since November 2019 and the fourth since late-January 2020. Following in the footsteps of Mk1, SN1, SN3, and SN4, SpaceX CEO Elon Musk has recently stated that Starship SN5 will be the first prototype to have three Raptor engines and a nosecone installed and could be the first to be outfitted with new and improved aerodynamic control surfaces.

In the meantime, Starship SN4 is perhaps less than 30 hours away from performing a third Raptor static fire test, potentially paving the way for the biggest challenge yet for a full-scale Starship prototype: powered flight. Scheduled no earlier than 9am CDT (14:00 UTC), May 13th, Starship SN4’s next static fire is meant to ensure that a replacement Raptor engine is functioning properly. If successful, the building-sized rocket will effectively be ready to attempt its first launch – also a first for the Starship program overall – pending FAA approval.

As illustrated in the unofficial diagram above, nearly all of the individual sections that will make up Starship SN5 appear to be more or less complete, excluding some ambiguity added by the interchangeable nature of some of the steel rings all Starships are built out of. For the current design and assembly strategy, Starships are comprised of eight separate sections, themselves made up of stacks of 2-4 steel rings. Altogether, excluding the conical nose section, a single Starship requires approximately 20 of those ~1.8m (6 ft) tall steel rings to reach its full height.

Currently, SpaceX has been focused on testing just the tank section of Starship prototypes, representing the vast majority of the technical challenges that must be solved to fully realize the next-generation launch vehicle’s ambitions. Excluding a smaller secondary liquid oxygen tank situated in the tip of Starship nosecones, the nose section is effectively irrelevant – putting the cart before the horse – until Starship tank sections are more of a known quantity.

When that would be the case was entirely up in the air until just the last week or so, when Starship SN4 became the first full-scale prototype to pass a cryogenic proof test, perform a wet dress rehearsal (WDR) with real propellant, complete static fire(s) with a Raptor engine installed, and – finally – pass a more challenging cryogenic pressure test in quick succession. With those milestones passed for the first time ever, SpaceX has effectively proven that it’s solved the what is arguably the most unprecedented aspect of its Starship program: building orbital-class pressure vessels for pennies on the dollar on the South Texas coast.

Of course, doing it once with Starship SN4 is not the same as fully confirming that SpaceX’s extremely exotic South Texas rocket factory is capable of producing repeatable results with future rockets. While incredibly improbable, Starship SN4’s multiple successes could be a fluke. Additionally, as Musk has noted, the goal is to complete two entire Starships every week once the factory is fully optimized. SpaceX has already achieved a monthly production rate for its current line of prototypes, an extremely encouraging sign for the practicality of Musk’s stretch goal.

In the prototype stage, that speed of production has been incredibly useful, enabling SpaceX to move at a pace of launch vehicle development almost unheard of since NASA’s Apollo Program. At the moment, Starship SN4 has passed all tests thrown at it so far and will soon be attempting the riskiest Starship test yet with its inaugural hop attempt. If the ship were to be destroyed, one would traditionally expect a bare minimum of a few months of program delay. Instead, Starship SN5 could be more or less complete even before SN4 receives FAA permission for its first flight, meaning that a replacement will already be ready to roll to the launch pad if or when SN4 is destroyed.

Aside from Starship SN5, SpaceX is also making great progress preparing Starship SN6’s various subsections. (NASASpaceflight – bocachicagal)

In a best-case scenario, if Starship SN4 continues to pass the tests thrown at it, including one or several hops, SpaceX will instead be entering a new phase indicative of what’s to come: the concurrent testing and operation of a fleet of Starships. A step further, if Starship SN4 succeeds, Starship SN5 appears to be on track to become the first prototype to have a full three Raptor engines and a nosecone installed, as well as the first to attempt a high-altitude (20 km/12 mi) flight test.

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Published

on

Tesla has officially launched the Model Y L in the United States and Puerto Rico for $61,990. It is the longer-wheelbase version of the Model Y, and has been available in China since last year.

Tesla brings the Model Y L to the U.S. just months after it phased out the only pure SUV in its lineup, the Model X. It is slightly longer than the Model Y configurations that are already available in the U.S., and features a three-row, six-seat setup with Captain’s Chairs being among the many features that make this a truly fantastic offering.

The Model Y L is priced competitively at $61,990, and features 325 miles of range and a 0-60 MPH in just 4.4 seconds.

Tesla also added a handful of new features that are not available in even the Premium Model Y. Here’s a full list of its features:

  • Heated/Ventilated Front Seats with Powered Thigh Cushion
  • Heated/Ventilated Captain’s Seats in Second Row with Powered Armrests & One-Touch Fold
  • Heated Third-Row Seats with Power Recline, One-Touch Fold & Child Seat Anchors
  • Improved Airflow, Increased Efficiency, More Range
  • 89 cubic feet of trunk space
  • Upgraded Acoustic Glass and Suspension to Minimize Road Noise
  • Adaptive Damping for a Smooth, Stable Ride
  • Staggered Tires for Enhanced Grip
  • Larger Tailgate for Better Rear Visibility and Bigger Windows Overall
  • 16″ First Row and 8″ Second Row Touchscreens
  • 19-Speaker Immersive Tesla Audio
  • 50W Wireless Charging Pads with Active Cooling and Charging Ports for All Other Seats
  • FSD Supervised and Integrated Grok AI

Tesla is also delivering these first units as a “Launch Series,” which comes with additional features, such as:

  • Door Trim Puddle Lights
  • Suede Dashboard Wing
  • Exterior and Interior Badging
  • Floor Mats
  • Sill Plates

The launch of the Model Y L in the U.S. marks a huge offering from Tesla to U.S. consumers. People have been calling for Tesla to bring a larger car to the U.S., and it needed it more than ever now that the Model X is gone.

It is a huge accomplishment for Tesla to get the Model Y L to the U.S., and after reporting strong deliveries today, it will be interesting to see how this car impacts future quarterly delivery reports.

Deliveries for the Model Y L “Launch Series” are slated for September or October of this year.

Tesla just told us twice that Model Y L is coming to the U.S.

Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.

The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.

The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.

With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.

However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.

Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.

Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.

Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.

Tesla is using vehicle microphones to improve build quality: here’s how

Published

Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.

It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.

As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.

The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.

It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.

Tesla’s ‘megacasts’ are key to massive build quality improvements

While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.

This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.

Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.
