SpaceX has almost completed a ‘test tank’ meant to ensure that Starship’s Super Heavy booster is capable of withstanding the immense thrust of more than two-dozen Raptor engines.

Believed to be known as test tank BN2.1, the prototype’s latest appearance comes on the heels of news from CEO Elon Musk that SpaceX has upgraded Super Heavy with one extra Raptor engine – with plans to add another three down the road. The results of that tank’s imminent test campaign will likely be crucial as the company shifts its focus sending Starship to orbit (or close) as soon as possible.

Prior to a new Super Heavy booster ‘thrust puck’ design first spotted on May 29th, at least two separate booster engine section prototypes completed in the last few months sported an earlier variant more akin to a donut. At that point, Super Heavy’s design had a central cluster of eight gimballing, throttleable Raptors surrounded by a ring of 20 Raptor Boost (“RBoost”) engines – a variant meant to trade the ability to throttle for ~25% more thrust.

While Super Heavy booster BN1’s almost immediate scrapping – prior to a single test – guaranteed that major design changes were on the way, exactly what those changes would be was anyone’s guess. The appearance of a new booster ‘thrust puck’ design and Musk’s subsequent announcement that Super Heavy will “initially” have 29 – not 28 – Raptors likely mean that that engine section redesign was a major contributor to BN1’s instant obsolescence. The only other major change SpaceX clearly made with booster BN2 was switching the positions of its liquid methane and liquid oxygen tanks, ensuring that Super Heavy’s heavier oxidizer is closer to the rocket’s base.

Musk also stated that SpaceX will eventually upgrade Super Heavy to 32 engines, giving future boosters a central cluster of 12 engines that the SpaceX CEO says will significantly improve the efficiency of boostback burns.

With 29 identical Raptors, the simplest possible Super Heavy booster would produce up to 5800 tons (12.8M lbf) of thrust at liftoff. If SpaceX has already completed Raptor Boost’s design and qualification and kicked off mass production of a 250-mTf engine, that liftoff thrust climbs to 6800 tons (~15M lbf). If SpaceX achieves performance goals (~210 mTf stock; ~300 mTf RBoost) mentioned by Musk last year, a 32-engine Super Heavy could achieve peak liftoff thrust greater than 8500 metric tons (~18.7M lbf).

Even in its weakest configuration, Super Heavy will still be more than 60% more powerful than Saturn V and 25% more powerful than N1 – the largest rockets to have ever successfully or unsuccessfully flown. That immense thrust demands a structure capable of surviving those extreme forces while simultaneously feeding dozens of Raptors up to ~28 metric tons (~61,000 lb) of propellant every second and withstanding several thousand tons of liquid oxygen – all without leaking, cracking, or flexing too much.

While BN2.1 wont have any of the plumbing associated with dozens of Raptors, nine hydraulic rams will let SpaceX subject its Super Heavy thrust structure to the simulated thrust of some number of engines. Given the presence of nine rams and nine clustered engines, it’s unclear if BN2.1 will only test that main thrust structure or if those rams will somehow be spread out to simulate the thrust of a full 29 engines – 20 of which will instead transfer most or all of their thrust into Super Heavy’s skirt.

Regardless, if successful, BN2.1’s test campaign should leave SpaceX on track to attempt Starship’s inaugural spaceflight as early as Q3 2021. If issues arise, that target could easily slip to Q4 or into 2022, but SpaceX’s test tank campaigns have historically been very successful.

Tesla to discuss expansion of Samsung AI6 production plans: report

Tesla has reportedly requested an additional 24,000 wafers per month, which would bring total production capacity to around 40,000 wafers if finalized.

Tesla is reportedly discussing an expansion of its next-generation AI chip supply deal with Samsung Electronics. 

As per a report from Korean industry outlet The Elec, Tesla purchasing executives are reportedly scheduled to meet Samsung officials this week to negotiate additional production volume for the company’s upcoming AI6 chip.

Industry sources cited in the report stated that Tesla is pushing to increase the production volume of its AI6 chip, which will be manufactured using Samsung’s 2-nanometer process.

Tesla previously signed a long-term foundry agreement with Samsung covering AI6 production through December 31, 2033. The deal was reportedly valued at about 22.8 trillion won (roughly $16–17 billion).

Under the existing agreement, Tesla secured approximately 16,000 wafers per month from the facility. The company has reportedly requested an additional 24,000 wafers per month, which would bring total production capacity to around 40,000 wafers if finalized.

Tesla purchasing executives are expected to discuss detailed supply terms during their visit to Samsung this week.

The AI6 chip is expected to support several Tesla technologies. Industry sources stated that the chip could be used for the company’s Full Self-Driving system, the Optimus humanoid robot, and Tesla’s internal AI data centers.

The report also indicated that AI6 clusters could replace the role previously planned for Tesla’s Dojo AI supercomputer. Instead of a single system, multiple AI6 chips would be combined into server-level clusters.

Tesla’s semiconductor collaboration with Samsung dates back several years. Samsung participated in the design of Tesla’s HW3 (AI3) chip and manufactured it using a 14-nanometer process. The HW4 chip currently used in Tesla vehicles was also produced by Samsung using a 5-nanometer node.

Tesla previously planned to split production of its AI5 chip between Samsung and TSMC. However, the company reportedly chose Samsung as the primary partner for the newer AI6 chip.

Elon Musk: Tesla could be first to build AGI in humanoid form

Musk’s statement was shared in a post on social media platform X.

Elon Musk predicted that Tesla could become one of the developers of Artificial General Intelligence (AGI) in humanoid form. Musk’s statement was shared in a post on social media platform X.  

In his post, Musk stated that “Tesla will be one of the companies to make AGI and probably the first to make it in humanoid/atom-shaping form.”

The comment comes as Tesla expands development of its Optimus humanoid robot.

During Tesla’s Q4 earnings report, Elon Musk stated that production of the Model S and Model X would be phased out at its Fremont, California, facility. The vehicles’ production line will then be converted to a pilot line for Optimus. Tesla is looking to produce 1 million units of the humanoid robots annually to start.

Musk has previously stated that Optimus could eventually function as a von Neumann probe. The concept, proposed by mathematician John von Neumann, describes a machine capable of replicating itself using planetary resources and sending those replicas to other worlds.

Optimus would likely only be able to achieve this potential if it manages to achieve Artificial General Intelligence.

Other leaders in the AI sector have also expressed strong expectations about AGI’s potential. Demis Hassabis, CEO of Google DeepMind, recently spoke about the technology at the India AI Impact Summit 2026, as noted in a Benzinga report.

“It’s going to be something like ten times the impact of the Industrial Revolution, but happening at ten times the speed,” Hassabis said.

Elon Musk’s recent comments about Tesla producing a product with AGI could hint at further collaboration among his companies. So far, Tesla is actively pursuing autonomous driving, but it is xAI that is pursuing AGI with its Grok program.

Considering that Elon Musk mentioned a Tesla humanoid product with AGI, it appears that an Optimus robot running xAI’s AI models could become a reality.

xAI had recently merged with SpaceX, though reports suggest that Elon Musk is also considering an even bigger merger for all his companies, including Tesla.

Tesla influencers argue company’s polarizing Full Self-Driving transfer decision

Tesla maintains it will honor transfers for orders with initial delivery windows before the deadline and offers full deposit refunds otherwise, citing longstanding fine print that the program is “subject to change at any time.”

Published

Tesla’s decision to tighten its Full Self-Driving (FSD) transfer promotion has ignited fierce debate among owners and enthusiasts.

The company quietly updated its terms in late February 2026, changing the eligibility from “order by March 31, 2026” to “take delivery by March 31, 2026.”

What began as a flexible incentive to boost sales, allowing buyers to transfer their paid FSD (Supervised) to a new vehicle, now excludes many, particularly Cybertruck owners facing delivery delays into summer or later.

Tesla maintains it will honor transfers for orders with initial delivery windows before the deadline and offers full deposit refunds otherwise, citing longstanding fine print that the program is “subject to change at any time.”

The reversal has polarized the Tesla community, with accusations of a “bait-and-switch” clashing against defenses of corporate pragmatism. Many owners who placed orders under the original wording feel betrayed, especially as production backlogs and new unsupervised FSD rollout complicate timelines.

However, Tesla has allowed them to cancel their orders and receive a refund.

Critics of the decision argue that the change disadvantages loyal customers who helped fund FSD development, calling it poor communication and a revenue grab as Tesla pivots toward subscriptions.

Popular influencers have amplified the divide. Whole Mars Catalog struck a measured but firm tone, acknowledging the original “order by” language but emphasizing Tesla’s right to adjust terms. He has continued to defend Tesla in this particular issue:

He criticized extreme backlash as “dramatization” and “spoiled kids,” noting the unsupervised FSD era and broader sales challenges make blanket transfers financially risky. Whole Mars advocated for polite outreach to CEO Elon Musk over the issue.

In a contrasting perspective, Dirty TesLA voiced sharper frustration, posting that blocking transfers feels “crazy” and distancing himself from “people that want to worship a corporation and say they can do no wrong.” His stance resonated with owners who view the policy flip as disrespectful to early adopters.

Popular Tesla influencer Sawyer Merritt captured the frustration felt by thousands. In a widely shared thread viewed over 700,000 times, Merritt detailed how pre-change Cybertruck orders now risk losing FSD eligibility unless their initial delivery window falls before March 31.

The controversy underscores deeper tensions—between Tesla’s need for revenue discipline and owners’ expectations of goodwill. As FSD evolves toward unsupervised capability, the community remains split: some see the change as necessary business, others as a broken promise. Whether Tesla reconsiders under pressure or holds firm remains to be seen, but it does not appear they are planning to budge.
