SpaceX sends Starship’s first vacuum Raptor engine to Boca Chica
For the first time, SpaceX has shipped a vacuum-optimized Raptor engine to its Boca Chica, Texas Starship factory days after the company’s present reiterated plans for an inaugural orbital launch attempt as early as July.
Back in March 2021, CEO Elon Musk confirmed that he’d set SpaceX a goal of attempting Starship’s first orbital launch no later than the end of July – around four and a half months distant at the time. Fifteen weeks later, though the prospects of an orbital launch attempt happening in July have practically shrunk to zero, SpaceX COO and President Gwynne Shotwell – best known for acting as a more grounded foil to Musk’s often impractical schedule estimates – reiterated that the company is still “shooting for July” for Starship’s first orbital launch attempt.
As of late June, hitting that target would require SpaceX to string together numerous extraordinary feats of engineering and rocketry in record time or attempt some extremely unorthodox corner-cutting.
The launch pad and launch vehicle hardware needed for Starship’s first space shot are currently far from ready for flight. On June 24th, Musk unexpectedly revealed that the Super Heavy booster prototype SpaceX is now in the late stages of assembly isn’t actually the booster that will carry Starship on its first space launch attempt. In other words, though dozens of rings in various states of work are strewn about SpaceX’s Boca Chica factory, the company has yet to begin assembling the massive 65m (~215 ft) tall booster required for the first orbital launch attempt.
Using Super Heavy Booster 3 (B3) as a ruler, assembly could easily take 9-10 weeks – starting whenever the process actually begins. If SpaceX started stacking Booster 4 today, in other words, it’s unlikely that the rocket would even be complete by the end of August. Barring SpaceX taking unprecedented shortcuts, completing the booster is just part of the process of preparing for flight and B4 would still need to be qualified for flight, likely involving at least one cryogenic proof and static fire test.
In a best-case scenario where SpaceX begins assembly today, manages to halve Booster 4 assembly time in one fell swoop, the sneaks the second Super Heavy ever completed through qualification testing in a single week, the orbital flight test booster still wouldn’t be ready for Starship installation (likely another unprecedented first) before mid-August.
That would then leave SpaceX five or six weeks to fully assemble Starship S20, a process that has yet to begin. Like Starship SN15, which Musk said sported “hundreds of improvements”, Musk has also stated that Ship 20 and all after it will feature another batch of upgrades needed to take Starship orbital. Starship SN15 was very gradually stacked and assembled over the course of almost four months, though that slow assembly can likely be blamed on the fact that SpaceX is busy testing Starships SN8 through SN11 and was effectively waiting to see if any other major changes might be required.
While most of S20’s upgrades are a mystery, the ship’s thrust dome – spotted in work at Boca Chica earlier this month – has already confirmed that the prototype will be the first with the necessary hardware for Raptor Vacuum engine installation. That likely means that S20 will also be the first Starship to attempt to static fire six Raptor engines*, potentially producing more thrust than a Falcon 9 booster. On June 27th, one such vacuum-optimized Raptor (RVac) arrived in Boca Chica for the first time ever, making it clear that the comparatively brand new engine may already be ready to start integrated Starship testing.
*Update: SpaceX CEO Elon Musk says that the Raptor Vacuum delivered to Boca Chica on June 27th is, in fact, meant for Starship S20, seemingly confirming that the prototype will fly with a full six Raptor engines.
Of course, beyond Starship and Super Heavy, SpaceX also has a great deal of work left to get the rocket’s first orbital-class launch facilities partially operational. SpaceX will need to complete and activate at least one or two more custom-built propellant storage tanks, sleeve those three or four tanks with three or four massive thermos-like ‘shells,’ complete thousands of feet of insulated plumbing and wiring, finish a massive ‘launch table,’ install that table on a six-legged ‘launch mount;’ outfit that table and mount with an array of power, avionics, hydraulics, and fueling equipment and plumbing; complete a ~145m (~475 ft) ‘integration tower,’ and perform the first fit checks and shakedown tests with a real booster or Starship.
Only then will SpaceX be able to attempt Starship’s first space launch. All told, it might not be literally impossible for SpaceX to complete all the above work in less than five weeks, but it’s safe to say that the odds of that happening could probably make a lottery ticket blush. Regardless, if Starship reaches orbit at any point before the end of 2021, it would beat out simpler “next-generation” rockets like Ariane 6, ULA’s Vulcan, and Blue Origin’s New Glenn despite beginning concerted development years later and with a far less certain funding situation.
Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.
The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.
🚨 The design uses electrically driven ducted fans, typically shown as a row of four at the rear, powered by the vehicle’s high-voltage battery.
The fans pull air from an underbody inlet, route it through ducts, and expel it from a larger rear outlet that functions as a… https://t.co/CHQB9u9UA3 pic.twitter.com/QVXmWTdggh

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.
Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.
The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.
The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.
Tesla Roadster event requires restricted airspace, and the FAA obliges
The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.
There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.
These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.
Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.
It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.
Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.
Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.
Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.
I’m at Tesla right now and when I walked into their showroom I was shocked to see it basically empty.
I asked one of the people working there where all of the cars are “Gone – it’s the end of the quarter and we’ve sold out of everything… including the display vehicles”So… pic.twitter.com/rN7s3gE6sJ

All the cars are gone from Tesla Century City!
All they have is Model Y L, a self-driving video playing on the background. I guess the best product is no product. Either that or they just sold the showroom cars. pic.twitter.com/mzCjWaXwww

Show room is empty. I asked and they have sold the demo cars too. Delivery numbers better be outstanding! pic.twitter.com/jq5N28Q6tZ

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.
Talking to the guys at the Mechanicsburg showroom on Friday, they couldn’t believe they had ANOTHER hauler coming in of cars for delivery—and each was accounted for
No car just sitting in inventory. They’re expecting a BIG quarter, and this is more than just the Y L https://t.co/ce801GkKVv

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.
In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.
Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.

Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.
Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”
The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.

The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.
Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.
Tesla plans big safety improvements for Full Self-Driving v15
Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.
Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.
