SpaceX has begun reinstalling three of the six Raptor engines that will power the first orbital-class Starship and repairing the heat shield that will hopefully protect it on its first trip to space.

Known as Starship 20 or S20, the 50m (~165 ft) tall steel rocket prototype has been stationed at one of SpaceX’s two suborbital testing pads since August 13th. No testing has been done, though, and a small army of SpaceX technicians and engineers have instead spent the last three or so weeks effectively turning a collection of steel tanks, tubes, and parts into a functional rocket. While it’s unclear why SpaceX chose to do that outfitting work at an unsheltered launch pad, new activity suggests that it may be almost complete.

Exactly one month ago, SpaceX stacked Starship S20 on top of Super Heavy Booster 4 (B4) on August 6th, briefly creating the largest rocket in history and completing a fit test that was admittedly just as much a photo op. Ship 20 was rapidly destacked and returned to SpaceX’s Starbase factory, where all six of its Raptor engines were removed. About a week later, Ship 20 returned to the pad and has remained installed on Suborbital Pad B ever since.

At the time, the implication was that SpaceX had removed Ship 20’s engines to allow the prototype to complete cryogenic proof testing with hydraulic thrust simulators. However, despite having carefully modified Pad B over several weeks for that exact purpose, those modifications were rapidly removed before Ship 20’s second rollout. Precluding a proof test with thrust simulation, the next logical conclusion was that SpaceX would still perform a cryogenic proof test before reinstalling Ship 20’s Raptors and moving on to a static fire campaign.

Now, even that appears to have been p1recluded. Instead, as if Ship 20 were the second or third or fourth in a series of prototypes, SpaceX rolled three center Raptors to Pad B on September 5th and began installing the engines on Starship on the 6th. It’s hard to say anything with confidence given how chaotically Starship S20’s to-be-determined qualification testing has changed in the last several weeks but, with plenty of uncertainty, Raptor installation implies that the vehicle will perform its first ambient pressure and cryogenic proof tests with engines installed.

It remains to be seen if Ship 20’s three vacuum-optimized Raptor engines will also be installed over the next few days (seemingly the logical assumption) or if SpaceX will instead complete proof tests and center Raptor static fire testing before finally moving into new territory. SpaceX has never static fired more than three Raptors at once and certainly never tested multiple Raptor Vacuum (RVac) engines in close proximity – let alone all six simultaneously.

Photos taken on August 18th, 28th, and September 3rd by Philip Bottin and Starship Gazer show the slow, steady process if finishing (and fixing) Starship S20’s heat shield.

Meanwhile, much of the focus of the last few weeks appears to have been on finishing Ship 20 plumbing and avionics wire runs, though it’s hard to say exactly what has been done. What is extremely visible and easy to follow, though, is the process of finishing the first orbital-class Starship heat shield and repairing a few hundred tiles broken during its pathfinder installation. SpaceX has installed 500-1000+ tiles on flown Starship prototypes like SN15 but the company has never come close to the ~15,000 needed to cover the entire windward side of the world’s largest rocket upper stage.

SpaceX has undertaken that process for the first time over the last six or so weeks and unsurprisingly seen a number of successes and failures. At some point along the way, a significant fraction of the ceramic, dinner-plate-sized tiles SpaceX technicians installed chipped, broke, shattered, or ran into other fitment issues. Over the last month or so, a great deal of progress has been made fixing those problem tiles and SpaceX has also more or less completed tile installation on the angular ‘aerocovers’ that protect Starship’s flap mechanisms – requiring dozens of custom tiles with complex shapes and curves.

As of September 6th, Starship S20’s heat shield appears to be around 95% complete and the installation of Raptor engines implies that the rocket’s plumbing, avionics, and tankage are also nearly finished. In other words, after many weeks of work, SpaceX’s first orbital-class Starship prototype could be ready to kick off cryoproof and static fire testing just a week or so (and maybe less) from now.

Tesla announces delivery timeline for Cybertruck in new market

“Coming soon! Estimated deliveries in Q1 for UAE.”

Tesla announced its delivery timeline for the Cybertruck as it heads to a new market.

Tesla Cybertruck deliveries started in the United States and Canada back in late 2023. However, the company has been looking to expand the all-electric pickup to new markets, including the Middle East, for which it opened up orders for earlier this year.

Initially, Tesla planned to launch deliveries late this year, but there has been a slight adjustment to the timeline, and the company now anticipates the pickup to make its way to the first adopters in the United Arab Emirates in Q1 2026.

This was confirmed by the Tesla Cybertruck program’s lead engineer, Wes Morrill:

Tesla first opened orders for the Cybertruck in the Middle East in mid-September of this year. It will be priced at AED 404,900 for the Dual Motor All-Wheel-Drive ($110,254) and AED 454,900 ($123,869) for the Cyberbeast trim.

The Cybertruck has been a highly anticipated vehicle in many parts of the world, but its ability to be sold in various regions is what is truly causing delays in the company’s efforts to bring the electric pickup worldwide.

Tesla confirms Cybertruck will make its way out of North America this year

In Europe, various agencies have challenged the design of the Cybertruck, arguing that it is unsafe for pedestrians due to its sharp edges and “boxy” design.

Agencies in the EU have said the vehicle’s “blade-like” protrusions are a violation of rules that ban sharp exterior edges that could cause severe injuries.

In Asia, Tesla will likely have to develop a smaller, more compact version of the vehicle as it does not align with local standards for urban environments. However, Tesla filed for energy consumption approval for the Cybertruck in December 2024, but there has been no real update on the status of this particular inquiry.

Overall, these issues highlight a real bottleneck in futuristic vehicle designs and the out-of-date regulations that inhibit the vehicle from becoming more widely available. Of course, Tesla has teased some other designs, including a more traditional pickup or even a compact Cybertruck build, but the company is not one to shy away from its commitments.

Nevertheless, the Cybertruck will appear in the Middle East for the first time in 2026.

Tesla teases new AI5 chip that will revolutionize self-driving

Published

Elon Musk revealed new information on Tesla’s AI5, previously known as Hardware 5, chip, for self-driving, which will be manufactured by both Samsung and TSMC.

The AI5 chip is Tesla’s next-generation hardware chip for its self-driving program, Optimus humanoid robots, and other AI-driven features in both vehicles and other applications. It will be the successor to the current AI4, previously known as Hardware 4, which is currently utilized in Tesla’s newest vehicles.

Elon Musk reveals Tesla’s HW5 release date, and that it won’t be called HW5

AI5 is specially optimized for Tesla use, as it will work alongside the company’s Neural Networks to focus on real-time inference to make safe and logical decisions during operation. It was first teased by Tesla in mid-2024 as Musk called it “an amazing design” and “an immense jump” from the current AI4 chip.

It will be roughly 4o times faster, have 8 times the raw compute, 9 times the memory capacity, 5 times the memory bandwidth, and 3 times the efficiency per watt.

It will be manufactured by both TSMC and Samsung at their Arizona and Texas fab locations, respectively.

Here’s what Musk revealed about the chip yesterday:

Different Versions

Samsung and TSMC will make slightly different versions of the AI5 chip, “simply because they translate designs to physical form differently.” However, Musk said the goal is that its AI software would work identically.

This was a real concern for some who are familiar with chip manufacturing, as Apple’s A9 “Chipgate” saga seemed to be echoing through Tesla.

Back in 2015, it was found that Apple’s A9 chips had different performances based on who manufactured them. TSMC and Samsung were both building the chips, but it was found that Samsung’s chips had shorter battery life than TSMC-fabricated versions.

Apple concluded that the variance was about 2-3 percent. However, Tesla will look to avoid this altogether.

Release and Implementation into Vehicles

Musk said that some samples will be available next year, and “maybe a small number of units” would equip the chip as well. However, high-volume production is only possible in 2027.

This means, based on Tesla’s own timeline for Cybercab production in Q2 2026, early iterations of the vehicle would rely on AI4. Many believe AI4 can be utilized for solved self-driving, but the power of subsequent versions, including AI5 and beyond, will be more capable.

AI6 and Beyond

AI6 will utilize the same fabs as AI5, but there would be a theoretical boost in performance by two times with this version.

AI6 could enter volume production by mid-2028. However, AI7, which Musk only briefly mentioned, “will need different fabs, as it is more adventurous.”

Tesla’s fully autonomous Cybercab made its first appearance in the Asia-Pacific region at the 8th China International Import Expo (CIIE) in Shanghai on November 5, becoming the centerpiece of an event that drew 12 of the world’s leading automakers. 

The new model offers a glimpse into Tesla’s driverless ride-hailing future, and based on the reception of the event’s attendees, it appears that Elon Musk’s vision is something that still resonates with people.

Tesla showcases its driverless vision with the Cybercab

At this year’s expo, themed “Mobility, Infinite Possibilities,” Tesla’s futuristic two-seat Cybercab stood out as a showcase of complete autonomy. According to Tesla staff, the vehicle lacks both a steering wheel and pedals, relying entirely on Tesla’s cameras and an end-to-end neural network designed for full self-driving.

The Cybercab will ultimately serve in the company’s expanding Robotaxi fleet, a cornerstone of Elon Musk’s long-promised autonomous mobility network. During the event, a Tesla employee emphasized that the Cybercab’s model’s compact layout reflects real-world usage, as 92% of trips involve just one or two passengers, as noted in a Sina News report. Trips that require more passengers could easily be handled by the Model 3 and Model Y, which are both capable of seating four, or even five passengers.

Optimus, Tesla’s humanoid robot that is designed for both home and industrial use, was also present at the event. Similar to the Cybercab, Optimus also attracted quite a lot of attention from the event’s attendees.

Automakers reaffirm commitment to Chinese innovation

Other global automakers, including Volkswagen, Mercedes-Benz, and Honda, also displayed cutting-edge concept cars and intelligent systems, but few captured the same interest as Tesla’s bold showcase of its autonomy and robotics.

Beyond new models, this year’s CIIE highlighted a renewed focus on local innovation and collaboration in China’s rapidly evolving EV landscape. Executives from Volkswagen, Audi, and General Motors reaffirmed that their long-term strategies center on “in China, for China,” strengthening R&D operations and forming tech partnerships with domestic suppliers.
