SpaceX is about to have a fleet of Starship rockets
SpaceX has finished the last major stacking event for the business half of its fifth full-scale Starship prototype, meaning that the company may be a week or less from having a fleet of Starships for the first time ever.
As of now, Starship serial number 5 (SN5) is on track to be completed in under a month, continuing a trend that SpaceX has managed over the entirety of 2020. Beginning in mid-January, SpaceX has completed several nosecone pathfinders, three test tanks, and three full-scale Starship prototypes – soon to be four once SN5 is finished. Once it is, however, SpaceX will be entering a new era of operations – fleet operations.
Up to this point, every full-scale Starship prototype and test tank SpaceX has built – excluding the tank SN2 was turned into in March – has been quickly destroyed over the course of one or two tests. For better or for worse, this has meant that SpaceX’s test and launch pad has always been more or less self-clearing, making way for the next prototype to roll out and begin testing after the scraps of its predecessor were removed. This time around, barring Starship SN4’s imminent demise, SpaceX will now have to deal with multiple completed Starship prototypes at the same time – a tiny taste of things to come.
For unknown reasons, SpaceX decided to swap out Starship SN4’s lone Raptor engine (likely SN18) after multiple wet dress rehearsals, partial engine tests, and two static fire tests – at least one of which was confirmed a success by CEO Elon Musk. Most recently, SpaceX removed Raptor SN18 to perform a more ambitious cryogenic pressure test, pushing Starship SN4’s propellant tanks all the way to 7.5 bar (~110 psi) at the same time as hydraulic rams simulated the thrust of three Raptor engines at the rocket’s base.
Instead of reinstalling Raptor SN18, SpaceX transported Raptor SN20 to the launch pad and installed it on Starship SN4 on May 10th, less than 24 hours after the prototype passed an orbital-class pressure test.
Aside from installing Raptor SN20, SpaceX teams have spent the last few days adding new COPVs (composite overwrapped pressure vessels) and plumbing to Starship SN4’s exterior – purpose largely unknown. While the new hardware is mostly a mystery, it is known that SpaceX is in the process of preparing SN4 and its new Raptor engine for a third wet dress rehearsal (WDR) and static fire test, necessary to ensure that Raptor SN20 is properly installed and functioning as expected.
Assuming that third static fire is successful, SpaceX’s will prepare Starship SN4 for its first flight, a ~150m (500 ft) hop test that will also be the first intentional flight of any full-scale Starship prototype since the program’s birth. For that hop test, SN4 will need some kind of attitude control system (ACS) thrusters to control its rotation and provide fine trajectory tuning to assist the ship’s lone Raptor engine. This is the likeliest explanation for the new hardware being installed on Starship SN4, as the ship does not currently appear to have ACS thrusters installed.

Of course, the first flight of a full-scale Starship prototype will probably be the riskiest test yet for the program and there’s a good chance that SN4 will meet its demise at some point during that flight. Enter Starship SN5.
As of May 12th, Starship SN5’s final two tank sections were stacked, effectively completing the most important half of the rocket (minus one final circumferential ring weld). SN5’s final outfitting of avionics and plumbing is still pending and will take at least a few days to a week or more, but that work can and has been completed after prototypes are transferred by road to the launch pad. Currently, Starship SN4 is occupying SpaceX’s one and only pad test stand, however, meaning that it wouldn’t make much sense to immediately move SN5 to the launch pad – at least until SN4 is done testing.
SN5 will also need a nose section and, perhaps, flaps installed, meaning that the full ship is likely still at least a week or two away from being finished, but that likely wont stop SpaceX from proof testing the rocket’s tanks if or when SN4 makes space at the launch pad.
According to comments made by Elon Musk, SN5 will likely become the first Starship prototype to have three Raptor engines installed and the first to attempt a truly high-altitude flight test if Starship SN4 is met with success in the coming weeks. As absurd as it feels to say, if SN5 completes triple-Raptor testing and a 20 km (~12 mi) flight test without issue, Musk has stated that the next step would be orbital flight tests. Starship SN6’s steel rings, meanwhile, are already being formed and stacked as SN5 nears completion.

Tesla pulls back the curtain on Cybercab mass production
Tesla’s Cybercab drives itself off the Gigafactory Texas line in a striking new production video.
Tesla has provided a first look from inside a production Cybercab as it drove itself off the assembly line at Gigafactory Texas. The video footage, posted on X, opens on the factory floor with robotic arms and assembly equipment visible through the Cybercab windshield, and follows the car through a branded tunnel marked “Cybercab”, before autonomously navigating itself to a holding lot.
The first Cybercab rolled off the Giga Texas production line on February 17, 2026, with Musk writing on X, “Congratulations to the Tesla team on making the first production Cybercab.” April marked the official shift to volume production. The Giga Texas line is being prepared to produce hundreds of units per week, with 60 units already spotted on the Gigafactory campus earlier this month.

The Cybercab was first revealed publicly at Tesla’s “We, Robot” event in October 2024 at Warner Bros. Studios in Burbank, California, where 20 pre-production units gave attendees rides around the studio lot. Musk said he believed the average operating cost would be around $0.20 per mile, and that buyers would be able to purchase one for under $30,000. The two-seat design is deliberate. Musk noted that 90 percent of miles driven involve one or two people, making a compact two-passenger vehicle the most efficient configuration for a fleet-scale robotaxi. Eliminating rear seats also removes complexity and cost, supporting that sub-$30,000 target.
Tesla’s annual production goal is 2 million Cybercabs per year once several factories reach full design capacity. The Cybercab has no steering wheel, no pedals, and relies entirely on Tesla’s vision-based FSD system. What the video shows is the first evidence of that system working not as a demo, but as a production reality, driving itself off the line and into the world.

Elon Musk’s last manually driven Tesla will do something no other production car will do
Elon Musk confirmed the Roadster as Tesla’s last manually driven car, with a debut coming soon.
During Tesla’s Q1 2026 earnings call on April 22, Elon Musk made a brief but notable comment about the long-awaited next generation Roadster while describing Tesla’s future vehicle lineup. “Long term, the only manually driven car will be the new Tesla Roadster,” he said. “Speaking of which, we may be able to debut that in a month or so. It requires a lot of testing and validation before we can actually have a demo and not have something go wrong with the demo.”
That single statement is the entire Roadster update from yesterday’s call, and while it represents another timeline shift, it comes as no surprise with Tesla heads-down-at-work on the mass rollout of its Robotaxi service across US cities, and the industrial scale production of the humanoid Optimus.
The fact that Musk specifically framed the Roadster as the last manually driven Tesla is significant on its own. As the rest of the lineup moves toward full autonomy, the Roadster becomes something rare in the Tesla-sphere by keeping the driver in control. Driving enthusiasts who buy a $200,000 supercar are not doing so to be passengers. They want the physical connection to the road, the feel of acceleration under their own input, and the experience of controlling something with that level of performance. FSD, however capable it becomes, removes that entirely. The Roadster signals that Tesla understands this distinction and is building a car specifically for the people who consider driving itself the point.
Tesla isn’t joking about building Optimus at an industrial scale: Here we go
The specs for the Roadster Musk has teased over the years are genuinely unlike anything in production. The base model targets 0 to 60 mph in 1.9 seconds, a top speed above 250 mph, and up to 620 miles of range from a 200 kWh battery. The optional SpaceX package takes it further, rumored to add roughly ten cold gas thrusters operating at 10,000 psi, borrowed directly from Falcon 9 rocket technology. With thrusters, Musk has claimed 0 to 60 mph in as little as 1.1 seconds. In a 2021 Joe Rogan interview he went further, stating “I want it to hover. We got to figure out how to make it hover without killing people.” Tesla filed a patent for ground effect technology in August 2025, suggesting the hover concept has not been abandoned. The starting price remains $200,000, with the Founders Series requiring a $250,000 full deposit. Some reservation holders placed those deposits in 2017 and are approaching a full decade of waiting.
With production now targeted for 2027 or 2028 at the earliest, the Roadster remains Tesla’s most audacious promise and its longest-running delay. But if what Musk is testing lives up to even half of what he has described, the demo alone should be worth waiting for.

Tesla confirmed HW3 can’t do Unsupervised FSD but there’s more to the story
Tesla confirmed HW3 vehicles cannot run unsupervised FSD, replacing its free upgrade promise with a discounted trade-in.
Tesla has officially confirmed that early vehicles with its Autopilot Hardware 3 (HW3) will not be capable of unsupervised Full Self-Driving, while extending a path forward for legacy owners through a discounted trade-in program. The announcement came by way of Elon Musk in today’s Tesla Q1 2026 earnings call.
🚨 Our LIVE updates on the Tesla Earnings Call will take place here in a thread 🧵

The history here matters. HW3 launched in April 2019, and Tesla sold Full Self-Driving packages to owners on the understanding that the hardware was sufficient for full autonomy. Some owners paid between $8,000 and $15,000 for FSD during that period. For years, as FSD’s AI models grew more demanding, HW3 vehicles fell progressively further behind, eventually landing on FSD v12.6 in January 2025 while AI4 vehicles moved to v13 and then v14. When Musk acknowledged in January 2025 that HW3 simply could not reach unsupervised operation, and alluded to a difficult hardware retrofit.
The near-term offering is more concrete. Tesla’s head of Autopilot Ashok Elluswamy confirmed on today’s call that a V14-lite will be coming to HW3 vehicles in late June, bringing all the V14 features currently running on AI4 hardware. That is a meaningful software update for owners who have been frozen at v12.6 for over a year, and it represents genuine effort to keep older hardware relevant. Unsupervised FSD for vehicles is now targeted for Q4 2026 at the earliest, with Musk describing it as a gradual, geography-limited rollout.
For HW3 owners, the over-the-air V14-lite update is welcomed, and the discounted trade-in path at least acknowledges an old obligation. What happens next with the trade-in pricing will define how this chapter ultimately gets written. If Tesla prices the hardware path fairly, acknowledges what early adopters are owed, and delivers V14-lite on the June timeline it committed to today, it has a real opportunity to convert one of the longest-running sore subjects among early adopters into a loyalty story.
