SpaceX appears to have delivered hardware that will eventually become part of the first 33-engine Super Heavy booster to its South Texas ‘Starbase’ factory.

Coming either from SpaceX’s Hawthorne, California headquarters and Falcon rocket factory or a smaller fabrication shop colocated on the company’s McGregor, Texas development and testing campus, the giant coin-like structure was spotted arriving at Starbase on Tuesday afternoon. Unlike Falcon boosters, the latest variant of which relies on a structure known as an octaweb that’s bolted together from dozens of structural elements, SpaceX has moved towards more monolithic ‘thrust pucks’ for Starship and Super Heavy.

Starship’s central ‘thrust puck’ is just two or so meters in diameter and designed to support the ship’s three gimballing Raptor Center (RC) engines. Super Heavy’s ‘puck’ is actually more like a giant steel coin than Starship’s almost conical thrust structure, measuring some 5-6 meters (16-20 ft) across but no more than a few inches (~10 cm) thick. It’s also designed to support a good deal more than three Raptors.

That’s where Tuesday’s deliver becomes significant. Unlike older booster thrust pucks, one of which was actually delivered to Starbase (likely for Super Heavy B6) just last week, this newer puck features a few design changes. Most importantly, it bumps the number of Raptor Center engine hardpoints to 13. Slightly earlier instances – including the puck currently packed with Raptors on Super Heavy Booster 4 (B4) – have an outer circle of eight Raptors and a ninth engine at the very center.

In line with comments made by CEO Elon Musk in early July, SpaceX’s newest Super Heavy thrust puck updates both figures, boosting the outer ring to ten engines and inner cluster to three engines for a total of 13 Raptors. Combined with a ring of 20 fixed Raptor Boost (RB) engines installed on the inside of Super Heavy’s aft skirt, a 13-engine puck will allow SpaceX to install up to 33 engines on Super Heavy boosters.

Using present-day first-generation Raptor 1 engines, a Super Heavy booster with 33 engines installed could produce up to 6100 tons (~13.5M lbf) of thrust at liftoff. Once SpaceX has qualified and ramped up production of next-generation Raptor 2 engines, Super Heavy’s max thrust at liftoff could jump to almost 7600 tons (~16.8M lbf) – more than twice that of the current record-holder, NASA’s famous Saturn V Moon rocket.

Given that the puck delivered on October 5th appears to be the first of its kind, there’s a decent chance that it will end up not on the first 33-engine Super Heavy – but on a small ‘test tank’ designed to qualify its structural changes. However, even if that’s the case, the next flight-grade 13-engine thrust puck will likely arrive at Starbase in just a month or two when SpaceX sets its sights on the assembly of that first 33-engine booster.

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

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.
