SpaceX Super Heavy booster assembly to start “this week,” says Elon Musk
CEO Elon Musk says that SpaceX is on track to begin fabricating Starship’s first Super Heavy booster prototype later “this week” and even revealed plans to hop that booster in the very near future.
Taller than an entire two-stage Falcon 9 or Falcon Heavy rocket, Super Heavy will be the largest and most powerful liquid rocket booster ever built by a factor of two (or more). Measuring ~70m (~230 ft) tall, Super Heavy will weigh at least 3500 metric tons (7.7 million lb) when fully loaded with liquid oxygen and methane propellant. According to Musk, SpaceX’s thrust target for the booster is 7500 tons (~16.5 million lbf) – significantly more than twice the thrust of the Saturn V and Soviet N-1 rockets and more than three times the thrust of SpaceX’s own Falcon Heavy.
On paper, while multiple times larger and more powerful, Super Heavy will be substantially simpler than Falcon Heavy thanks to its single-core. Built out of the same simple steel rings used to assemble Starship prototypes, Super Heavy should also be substantially cheaper to build than Falcon Heavy. Thanks to the experience SpaceX has already gained through months of Starship production, testing, and iterative improvement, initial Super Heavy prototype production could have a much smoother start, but several major challenges remain.
SpaceX has structured its Starship development program in such a way that the hardest technical challenges are generally first in line. Raptor engine testing came first in September 2016, although SpaceX did simultaneously build and test a full-scale carbon composite liquid oxygen – a material choice that was ultimately made redundant by the move to steel in late 2018. Up next, Starhopper served as a sort of proof of concept for the assembly of a flightworthy steel rocket in an unprotected open-air tent.
Starship Mk1 came next and was built as a full-scale prototype in similarly spartan conditions – but with much thinner steel. Mk1 ultimately failed prematurely, serving as a catalyst for SpaceX to substantially upgrade its South Texas rocket production capabilities, as well as its manufacturing techniques. Beginning in January 2020, SpaceX completed a rapid-fire series of tests with three stout tank prototypes and five full-scale Starship tank sections over the next seven months, passing multiple challenging pressure tests, wet dress rehearsals, Raptor static fires, and even a 150m (500 ft) hop.
The biggest challenges still facing Starship (5+ minute Raptor burns, skydiver-style landings, heat shield qualification, orbital launch/reentry/reuse) are mostly unique to the orbital spacecraft. In other words, with all SpaceX has already accomplished so far with Starship development, it could very well be ready to build a fully-capable Super Heavy prototype right now.
Along those lines, Musk says that there’s a chance that SpaceX will be ready to hop a Super Heavy booster prototype as early as October 2020 – less than two months after the first prototype enters production. Musk also noted that the biggest technical challenge facing Super Heavy is its extraordinarily complex ‘thrust puck’ – a metal structure that must host up to 28 Raptor engines and transfer all of their thrust through the rest of the rocket.
Per past comments, SpaceX will begin booster testing – possibly up to and including the first few orbital launch attempts – with as few Raptor engines as possible. For Musk’s aforementioned booster hop test, Super Heavy could reportedly hop with as few as two Raptors installed. Beyond those early tests and Super Heavy thrust puck development, perhaps only other challenge facing SpaceX is finalizing Raptor’s design to the point that dozens of engines can be built in short order. As of now, SpaceX has completed 40 Raptor prototypes in 18 months, while every Starship/Super Heavy pair will need as many as 34 engines apiece.

Tesla will resolve its massive recall of nearly three million vehicles in China with stickers and a software update.
On Friday, Chinese regulators filed recall plans against Tesla, Xiaomi, Leapmotor, Xpeng, Chery, Geely, Dongfeng, Arcfox, and FAW to resolve what is essentially a carbon-copy issue throughout each of the companies’ vehicle models: emergency door release latches are simply not visible enough.
Tesla door handle saga gets its latest chapter and a big change is coming
The companies will be required to add things that will make these latches, which will open the door in the event of an emergency, more visible. Of the 7 million vehicles impacted, Tesla accounts for 2,975,910 units. More than 1.9 million of those are Model Y vehicles, with the rest, just over 970,000, being Model 3s.
To resolve the issue, Tesla is going to add warning labels to the emergency latches free of charge, and then utilize an Over-the-Air update to add a post-crash window-lowering strategy, according to CNEVpost.
This massive effort to fix the all-electric Model Y and Model 3’s emergency latch system comes just months after several probes across various markets identified the trouble some had identifying this latch. Those who had gotten involved in car accidents that stripped the vehicle of its power were not aware that every Tesla has emergency door latches.
China’s State Administration for Market Regulation (SAMR) said that severe crashes that disable a vehicle’s low-voltage system could not only hinder occupants from getting out, but also make it more difficult for emergency response workers to gain entry.
SAMR is starting to tighten the regulations it has on door handles on vehicles. A new mandatory national standard will take effect for all models starting January 1, 2027, and will require all doors to be equipped with mechanical release mechanisms. This will effectively end purely electronic door handles. Models already on sale with type approval have been granted a two-year transition period, which will enable things to change until January 2029.
Tesla has officially confirmed plans to bring its all-electric Semi truck to Europe, with full specifications and market-launch details set for unveiling at the IAA Transportation trade fair in Hannover, Germany.
The event runs September 15–20, with a possible press preview on September 14. The announcement, shared via Tesla’s Semi account, marks a significant expansion beyond North America nearly nine years after the truck’s original 2017 reveal.

In the United States, the Semi’s path has been gradual. Limited pilot production and customer deliveries began in late 2022, primarily to fleets such as PepsiCo. After years of refinement, high-volume manufacturing started on April 29, 2026, at a dedicated facility adjacent to Gigafactory Nevada.
The plant targets an annual capacity of 50,000 units, though the ramp is expected to be gradual, with “many thousands” of trucks projected by the end of 2026.
Demand is building, with recent orders including 500 units for Einride (deliveries starting September 2026, serving Amazon and others) and hundreds more from operators such as WattEV. Pricing stands at approximately $260,000 for the Standard Range and $290,000 for the Long Range before incentives.
Tesla Semi pricing revealed after company uncovers trim levels
Earlier in 2026, Tesla finalized production specifications that incorporated substantial updates. In February, the company detailed two variants designed for a full 82,000-pound gross combination weight.
The Standard Range offers about 325 miles of range with a 548 kWh battery and curb weight under 20,000 pounds. The Long Range delivers roughly 500 miles with an 822 kWh pack and a 23,000-pound curb weight. Both use three independent rear-axle motors producing up to 800 kW (about 1,073 horsepower), achieve energy consumption of around 1.7 kWh per mile, and support megawatt-class charging at up to 1.2 MW—recovering about 60 percent of range in 30 minutes through the MCS standard.
Additional refinements include a roughly 1,000-pound weight reduction versus earlier prototypes, improved aerodynamics, a 48-volt electrical architecture, electric power take-off up to 25 kW for refrigerated trailers, and fleet management software with over-the-air updates.
These advances position the Semi as a competitive option against diesel trucks on operating costs and performance. For Europe, adaptations such as lighting, cab configurations (including potential sleeper options), and regulatory compliance are anticipated.
With series production underway in Nevada and major fleet commitments secured, the upcoming IAA reveal will clarify timelines, European-specific specs, and pricing, potentially accelerating electrification of heavy-duty freight on both continents.

Tesla Robotaxi gets a massive upgrade in Nevada
Nevada regulators just approved a massive expansion of Tesla’s robotaxi fleet across the entire county.
Tesla’s robotaxi footprint in Nevada just grew by roughly 500 times in a single regulatory vote.
The Nevada Transportation Authority approved Tesla’s full Autonomous Vehicle Network Company permit on Thursday, clearing the way for the company to deploy up to 5,000 driverless vehicles across Clark County over the next 12 months. The decision came during a four hour general session meeting that Tesla investor Sawyer Merritt watched live and reported on X, noting the vote replaces the interim order that had limited Tesla to just 10 robotaxis on a narrow stretch of the Las Vegas Strip.

That earlier cap, covered here after it surfaced on August 13, came with restrictions that looked stricter than what Tesla runs in Austin: a 45 mph speed ceiling, no airport pickups, and a geofence confined to the Strip corridor. The new approval extends Tesla’s operating authority to all of Clark County, with room to request an even wider geofence across the state.
Tesla representatives at the meeting said they have no intention of putting 5,000 cars on the road right away. Commercial rides are expected to start within 30 days, pending vehicle inspections, insurance filings, and fare approval, the standard steps every robotaxi operator in Nevada has had to clear.
Tesla’s own Robotaxi account replied to the news with a short line, The golden future is upon us.
The timing lines up with Tesla’s broader robotaxi push this month. The company is preparing to open Cybercab rides to the public in Austin as soon as this month, and it opened a sweepstakes for riders to win a seat at the launch event. Tesla filed its original application for a 5,000 vehicle Nevada fleet back in June, a request regulators trimmed to 10 vehicles when they issued the interim order in July. Thursday’s vote effectively grants the number Tesla asked for from the start.
Zoox, the Amazon owned robotaxi operator, has run in Nevada since 2025 and was capped at 100 vehicles before Thursday’s decision. Tesla’s new ceiling puts it well ahead of that comparison on paper, though the company has said its actual fleet size will depend on how quickly FSD v15 rolls out, the software update executives have called the gateway to scaling unsupervised robotaxi operations nationwide.
