Tesla Model S and Model X refresh official webpages hint at potential ‘megacast’ use
Recent updates to Tesla’s official Model S and Model X pages hint that the electric car maker may be poised to roll out some notable changes to the underbody of its flagship vehicles. Based on images that Tesla has shared online, it appears that the Model S and Model X refresh may very well be receiving the company’s now-iconic “megacast” on their rear underbody.
Observations about the update were shared by the electric vehicle community on Twitter, with Tesla investor-enthusiast Eric Anderson noting that the Model S refresh’s webpage now features what seems like a megacast on the flagship sedan’s rear frame. As could be seen in the image below, the body of the Model S refresh on Tesla’s website today differs significantly compared to the Raven Model S depicted on the site prior to the Q4 FY 2020 Earnings Call.

Interestingly enough, hints of the megacast’s use in Tesla’s flagship vehicles do not seem to end with the Model S refresh. A look at the Model X refresh’s updated webpage also shows the flagship SUV’s rear underbody featuring a megacast-like component. With this in mind, it appears that Tesla has done some serious work on the bodies of its flagship vehicles, making them more cost-effective to produce and possibly even making their quality better.

Much of the information available for the Model S and Model X refresh are focused on the vehicles’ new interior and features, which are undoubtedly industry-leading in their own right. That being said, Tesla’s Q4 FY 2020 Update Letter did not just include references to updated battery modules, packs, and drive units for the two vehicles; the EV maker also hinted at “other improvements” that were done to the Model S and Model X. Perhaps some of these improvements include the use of larger casted parts.
Model S and X are now once again Tesla's tech leaders. All The latest bleeding-edge versions of all of their technology.

Granted, Tesla only has two IDRA Giga Press machines in the Fremont Factory that are capable of producing single-piece megacasts, and those are expected to be used for the Model Y. That being said, even a two-piece megacast setup, such as those used by the EV maker in the Model Y’s early builds, could be a game-changer for the Model S and Model X refresh.
Automotive expert Sandy Munro has noted that the use of megacasts such as those in the Model Y can usher in numerous improvements for Tesla, from production cost to build efficiencies. Munro also noted that megacasts could help Tesla improve its build quality, since lesser parts provide fewer areas where errors in the assembly process could occur. With this in mind, the apparent use of megacasts for the Model S and Model X refresh could herald a breed of flagship Teslas whose build quality matches their tech.

xAI’s Grok approved for Pentagon classified systems: report
Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations.
Elon Musk’s xAI has signed an agreement with the United States Department of Defense (DoD) to allow Grok to be used in classified military systems.
Previously, Anthropic’s Claude had been the only AI system approved for the most sensitive military work, but a dispute over usage safeguards has reportedly prompted the Pentagon to broaden its options, as noted in a report from Axios.
Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations.
The publication reported that xAI agreed to the Pentagon’s requirement that its technology be usable for “all lawful purposes,” a standard Anthropic has reportedly resisted due to alleged ethical restrictions tied to mass surveillance and autonomous weapons use.
Defense Secretary Pete Hegseth is scheduled to meet with Anthropic CEO Dario Amodei in what sources expect to be a tense meeting, with the publication hinting that the Pentagon could designate Anthropic a “supply chain risk” if the company does not lift its safeguards.
Axios stated that replacing Claude fully might be technically challenging even if xAI or other alternative AI systems take its place. That being said, other AI systems are already in use by the DoD.
Grok already operates in the Pentagon’s unclassified systems alongside Google’s Gemini and OpenAI’s ChatGPT. Google is reportedly close to an agreement that will result in Gemini being used for classified use, while OpenAI’s progress toward classified deployment is described as slower but still feasible.
The publication noted that the Pentagon continues talks with several AI companies as it prepares for potential changes in classified AI sourcing.

Elon Musk denies Starlink’s price cuts are due to Amazon Kuiper
“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X.
Elon Musk has pushed back on claims that Starlink’s recent price reductions are tied to Amazon’s Kuiper project.
In a post on X, Musk responded directly to a report suggesting that Starlink was cutting prices and offering free hardware to partners ahead of a planned IPO and increased competition from Kuiper.
“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X. “The lower the cost, the more Starlink can be used by people who don’t have much money, especially in the developing world.”
The speculation originated from a post summarizing a report from The Information, which ran with the headline “SpaceX’s Starlink Makes Land Grab as Amazon Threat Looms.” The report stated that SpaceX is aggressively cutting prices and giving free hardware to distribution partners, which was interpreted as a reaction to Amazon’s Kuiper’s upcoming rollout and possible IPO.
In a way, Musk’s comments could be quite accurate considering Starlink’s current scale. The constellation currently has more than 9,700 satellites in operation today, making it by far the largest satellite broadband network in operation. It has also managed to grow its user base to 10 million active customers across more than 150 countries worldwide.
Amazon’s Kuiper, by comparison, has launched approximately 211 satellites to date, as per data from SatelliteMap.Space, some of which were launched by SpaceX’s Falcon 9 rocket. Starlink surpassed that number in early January 2020, during the early buildout of its first-generation network.
Lower pricing also aligns with Starlink’s broader expansion strategy. SpaceX continues to deploy satellites at a rapid pace using Falcon 9, and future launches aboard Starship are expected to significantly accelerate the constellation’s growth. A larger network improves capacity and global coverage, which can support a broader customer base.
In that context, price reductions can be viewed as a way to match expanding supply with growing demand. Musk’s companies have historically used aggressive pricing strategies to drive adoption at scale, particularly when vertical integration allows costs to decline over time.

Tesla Giga Berlin makes a statement of solidarity amid IG Metall conflict
The display comes as tensions between Tesla and IG Metall continue to escalate.
Tesla Giga Berlin is sending a strong message of solidarity amid its ongoing legal dispute with German union IG Metall.
In a post on social media platform X, Giga Berlin plant manager André Thierig shared an image of the facility’s lobby covered with a large banner that reads: “Progress. Innovation. Success.” He added that the slogan reflects what the facility has stood for since Day One.
“Our lobby at Giga Berlin covered in a huge banner these days. Progress. Innovation. Success – this is what we stand for since we started production in 2022 and how we will go into our future!” Thierig wrote in his post on X.
The display comes as tensions between Tesla and IG Metall continue to escalate.
The dispute began after Tesla accused a union representative of secretly recording a works council meeting at Giga Berlin. Tesla stated that it filed a criminal complaint after the alleged incident. Police later confirmed they had seized a computer belonging to an IG Metall member as part of their investigation.
“What has happened today at Giga Berlin is truly beyond words! An external union representative from IG Metall attended a works council meeting. For unknown reasons he recorded the internal meeting and was caught in action! We obviously called police and filed a criminal complaint!” Thierig wrote on X at the time.
IG Metall denied the accusation and characterized Tesla’s move as an election tactic ahead of upcoming works council elections. The union subsequently filed a defamation complaint against Thierig. Authorities later confirmed that an investigation had been opened in connection with the matter.
Giga Berlin began production in 2022 and has since become one of Tesla’s key European manufacturing hubs, producing the Model Y, the company’s best-selling vehicle. The facility has expanded capacity over the past years despite environmental protests, labor disputes, and regulatory scrutiny.
