SpaceX installs more than two dozen Super Heavy Raptor engines in one night

In a virtually unprecedented feat of engineering and rocketry, SpaceX appears to have installed a full 29 Raptor engines on Starship’s first flightworthy Super Heavy booster in a single evening.

After accepting delivery of five new Raptor engines earlier the same day, Super Heavy Booster 4’s (B4) first Raptor rolled out of one of SpaceX’s Starship factory tents around 6pm CDT to form what would become a line of engines awaiting installation. One by one, Raptors were rolled out of that tent and by 5am CDT, an incredible 25 engines had been spotted and installed on Super Heavy. Come shift handoff around 6am, 27 Raptors had reportedly been installed in 12 hours. The two remaining engines likely joined them an hour or two later, marking 29 high-performance rocket engines installed in just 12-14 hours.

Historically, only one other feat of rocketry comes close. In the late 1960s and early 1970s, the Soviet Union was able to install its Saturn V-class “N1” Moon rocket’s 30 engines in just two days. Its NK-15 engines were about the same size as Raptor, approximately 80% as powerful, and collectively formed the most powerful rocket booster ever flown – though N1 never managed a fully successful launch before the program was canceled.

The base of the Soviet N1 rocket’s first stage.

Of course, three of N1’s four test flights ultimately failed as a result (direct or indirect) of challenges with the first stage and its 30 NK-15 engines, marring their ~48-hour installations with the possibility that a less rushed procedure might have prevented issues that later doomed the rocket. The same is somewhat true for Super Heavy Booster 4, given that it’s unclear when the rocket will actually fly. B4 will also need to complete static fire testing – likely making it the most powerful rocket booster ever fired – before its current design and rapid Raptor installation can be considered an unqualified success.

Regardless, given that it was the first time SpaceX has ever attempted to install more than three Raptor engines on a Starship or Super Heavy prototype, managing 29 Raptors in half a day bodes very well for the engine’s ease of installation. Notably, with 29 engines installed, Super Heavy Booster 4 also technically has more thrust potential than any other rocket booster in history. With around 185 tons of thrust each at sea level, a 29-engine static fire could produce almost 5400 tons (~11.9M lbf) of thrust, beating out the Soviet N1 rocket’s ~4630 tons (~10.2M lbf).

SpaceX could reportedly roll Super Heavy Booster 4 to Starship’s nascent orbital launch pad as early as Tuesday, August 3rd, where the ‘launch table’ the rocket might rest on was just installed mere days ago.

Tesla has officially begun the wide rollout of Full Self-Driving (Supervised) v14 to the Cybertruck about a month after the company started rolling it out to other vehicles in the fleet.

On Monday, Tesla officially started rolling out v14.1.5 to Cybertruck owners, the first FSD v14 rollout for owners of the all-electric pickup.

Owners have been anxiously waiting for Tesla to begin the wide release of v14 to Cybertruck, as the company said it would refine the suite for the vehicle.

Tesla has finally started rolling out to many owners, who are reporting that their Cybertrucks are downloading Software Update 2025.38.8.5, which contains FSD v14.1.5:

Tesla has to be more cautious with rolling out FSD on the Cybertruck than on other vehicles for a few reasons. Initially, the Cybertruck utilizes an all-wheel steering system that turns differently than the S3XY lineup. This creates a challenge for the Tesla AI team as they have to cater to this specific maneuvering change.

Additionally, the Cybertruck is much larger, and the exterior cameras responsible for seeing the vehicle’s surroundings are placed differently than those of the other vehicles.

This requires additional calibration to ensure safety.

The full release notes for Full Self-Driving v14.1.5 are as follows:

  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, in a Parking Garage, or at the Curbside.
  • Added handling to pull over or yield for emergency vehicles (e.g. police cars, fire trucks, ambulances).
  • Added navigation and routing into the vision-based neural network for real-time handling of blocked roads and detours.
  • Added additional Speed Profile to further customize driving style preference.
  • Improved handling for static and dynamic gates.
  • Improved offsetting for road debris (e.g. tires, tree branches, boxes).
  • Improve handling of several scenarios including: unprotected turns, lane changes, vehicle cut-ins, and school buses.
  • Improved FSD’s ability to manage system faults and recover smoothly from degraded operation for enhanced reliability.
  • Added alerting for residue build-up on interior windshield that may impact front camera visibility. If affected, visit Service for cleaning!

Elon Musk shuts down Tesla ‘AMG’ division speculation: ‘Focus is autonomy’

“I think it’s best to leave that to the custom shops. Tesla’s focus is autonomous cars, building futuristic autonomous cars. We want the future to look like the future.”

Tesla CEO Elon Musk was asked by Joe Rogan late last week whether the company would ever consider establishing an “AMG division” like Mercedes-Benz has established for powerful, race-inspired vehicles.

However, Musk turned down any talk of that, highlighting that the company is laser-focused on autonomous vehicles, seemingly hinting that any distraction from autonomy would be a detriment to the future.

Rogan drives a Tesla Model S himself, but it is not your run-of-the-mill all-electric sedan. Already outfitted with the Plaid powertrain that Tesla developed, Rogan took his vehicle to Unplugged Performance for a true performance outfitting.

The vehicle is completely overhauled with performance parts and seats. Known as the Model S-APEX, Rogan took delivery of it from Unplugged in January.

Rogan asked Musk on Friday during his most recent appearance on the Joe Rogan Experience podcast whether Tesla would ever establish an “AMG division” that would focus on catering Teslas to performance-based standards.

Musk said:

“I think it’s best to leave that to the custom shops. Tesla’s focus is autonomous cars, building futuristic autonomous cars. We want the future to look like the future.”

Tesla fans have said for years that the company should consider acquiring Unplugged Performance and its Upfit Tesla division, which recently outfitted the Las Vegas Metropolitan Police Department’s fleet of Cybertruck cruisers.

However, it seems Tesla will keep things separate. Musk is primarily focused on autonomy, which will drive the technology forward and drive shareholder growth. Something like an outfitter for performance would be a cool thing for the owners who have the interest and the money.

It’s not a tremendous revenue driver or anything that would contribute to the financial state of the company. Mercedes-Benz, for example, is more accessible for consumers as it sold over 140,000 units from its AMG brand in 2024.

It helps with driving revenue higher by as much as 15 percent compared to similar models that are not AMGs. However, would Tesla see this much of a benefit? Likely not, because the Performance trim already caters to many owners.

Tesla Cybertruck fleet takes over at SpaceX’s Starbase

Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.

Tesla Cybertrucks have taken over at SpaceX’s Starbase facility in Texas, as hundreds of the all-electric pickup trucks were spotted late last week rounding out a massive fleet of vehicles.

The Cybertruck fleet is geared toward replacing gas vehicles that are used at Starbase for everyday operations. The only surprise about this is that it was not done sooner:

Deliveries have been going on for a few weeks, as Cybertrucks have made their way across the state of Texas from Austin to Starbase so they could be included in SpaceX’s fleet of vehicles at the facility.

Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.

However, there are some other perspectives to consider as SpaceX is utilizing such a massive fleet of Cybertrucks. Some media outlets (unsurprisingly) are seeing this as a move of weakness by both Tesla and SpaceX, as the aerospace company is, in a sense, “bailing out” lagging sales for the all-electric pickup.

It’s no secret that Tesla has struggled with the Cybertruck this year, and deliveries have been underwhelming in the sense that the company was anticipating between 1 million and 2 million orders for the vehicle before it was widely produced.

A lot of things changed with the Cybertruck between its 2019 unveiling and 2023 initial deliveries, most notably, price.

The price of the Cybertruck swelled significantly and priced out many of those who had pre-ordered it. Some have weighed the option of whether this purchase was a way to get rid of sitting inventory.

However, it seems more logical to consider the fact that SpaceX was likely always going to transition to Teslas for its fleet, especially at Starship, at some point.

It doesn’t seem out of the question that one Musk company would utilize another Musk company’s products, especially considering the Cybertruck has been teased as the vehicle that would be present on Mars.
