Tesla Armor Glass patent reveals ‘bulletproof’ secret to Cybertruck durability
Tesla rolled out several new patents related to the Cybertruck today, one of them being the “bulletproof” Armor Glass that CEO Elon Musk talked about on several occasions. The Cybertruck’s durability has been one of the vehicle’s most notorious features. The patent describes the multi-layered design that Tesla will use across several of its cars to prevent owners from spending big bucks on new windshields or windows after a scratch, crack or chip.
Perhaps the most notable memory from the Cybertruck event in November 2019 was when Tesla Chief Designer Franz von Holzhausen threw a metal ball at the Cybertruck’s driver’s door glass after slamming the stainless steel exoskeleton with a sledgehammer. After claiming the glass was durable enough to sustain several blows without cracking, the window did smash with the signature broken spheres imprinted into everyone’s mind who watched the event.

Elon Musk stated that Franz’s initial sledgehammer hits damaged the base of the glass, weakening them to the point that the steel balls were able to easily break it. Musk proved later that the windows really were super durable by releasing a video of Franz throwing the same metal balls at the glass right before the Cybertruck was rolled out on stage. Now, the patent explains how Tesla created durable and near-indestructible automobile glass.
According to the patent, the combination of the “multi-layer glass stack” has about a 10% chance of failure with an impact of 2 J.
Tesla’s multi-layer glass stack is comprised of the following: an inner-facing layer that has been chemically strengthened with high strength in flexibility. It measures between .5 and 1.1 millimeters thick and has an adhesive interlayer, which conjoins it to an outer-facing layer that has energy absorptive properties. The outer layer includes “non-soda lime, low-CTE, high densification glass” that measures between 2 and 5 millimeters thick. The two layers and then joined together by the energy absorbent adhesive. The outer layer is comprised of borosilicate, a low-melting-point glass made from silica and boric oxide that is more resistant to thermal shock than any other common glass.
Tesla focused heavily on the process of creating a highly durable automotive glass that would be able to withstand normal instances on the road and remain damage-free during operation. The patent states that, typically, automotive glass can be chipped, cracked, or broken without much external force; something as small as a pebble that is launched into the air by another vehicle can cause enough damage to warrant an entire windshield replacement. Tesla wanted to avoid this as windshields can be expensive and difficult to replace.

In fact, the external-facing layer, in some embodiments, has the ability to resist crack initiation and crack propagation, making it durable in the event of a collision or if a foul ball happens to hit some glass when you’re at your kid’s little league game. It doesn’t appear that the Cybertruck will be the only vehicle to utilize the glass, as another illustration within the patent shows a sedan.
When Musk joined Jay Leno in a Cybertruck ride that was aired on MSNBC’s Jay Leno’s Garage a year ago today, the former late-night TV show host asked the Tesla CEO why anyone would want bulletproof, armored glass on their truck.
“Because it’s badass, and it’s super cool,” Musk quickly replied. “Do you want your truck to be bulletproof or not?”

Tesla adds a new feature to Navigation in preparation for a new vehicle
After CEO Elon Musk announced earlier this week that the Semi’s mass production processes were scheduled for later this year, the company has been making various preparations as it nears manufacturing.
Tesla has added a new feature to its Navigation and Supercharger Map in preparation for a new vehicle to hit the road: the Semi.
After CEO Elon Musk announced earlier this week that the Semi’s mass production processes were scheduled for later this year, the company has been making various preparations as it nears manufacturing.
Elon Musk confirms Tesla Semi will enter high-volume production this year
One of those changes has been the newly-released information regarding trim levels, as well as reports that Tesla has started to reach out to customers regarding pricing information for those trims.
Now, Tesla has made an additional bit of information available to the public in the form of locations of Megachargers, the infrastructure that will be responsible for charging the Semi and other all-electric Class 8 vehicles that hit the road.
Tesla made the announcement on the social media platform X:
We put Semi Megachargers on the map

Although it is a minor development, it is a major indication that Tesla is preparing for the Semi to head toward mass production, something the company has been hinting at for several years.
Nevertheless, this, along with the other information that was released this week, points toward a significant stride in Tesla’s progress in the Semi project.
Now that the company has also worked toward completion of the dedicated manufacturing plant in Sparks, Nevada, there are more signs than ever that the vehicle is finally ready to be built and delivered to customers outside of the pilot program that has been in operation for several years.
For now, the Megachargers are going to be situated on the West Coast, with a heavy emphasis on routes like I-5 and I-10. This strategy prioritizes major highways and logistics hubs where freight traffic is heaviest, ensuring coverage for both cross-country and regional hauls.
California and Texas are slated to have the most initially, with 17 and 19 sites, respectively. As the program continues to grow, Florida, Georgia, Illinois, Washington, New York, and Nevada will have Megacharger locations as well.
For now, the Megachargers are available in Lathrop, California, and Sparks, Nevada, both of which have ties to Tesla. The former is the location of the Megafactory, and Sparks is where both the Tesla Gigafactory and Semifactory are located.

Tesla stock gets latest synopsis from Jim Cramer: ‘It’s actually a robotics company’
“Turns out it’s actually a robotics and Cybercab company, and I want to buy, buy, buy. Yes, Tesla’s the paper that turned into scissors in one session,” Cramer said.
Tesla stock (NASDAQ: TSLA) got its latest synopsis from Wall Street analyst Jim Cramer, who finally realized something that many fans of the company have known all along: it’s not a car company. Instead, it’s a robotics company.
In a recent note that was released after Tesla reported Earnings in late January, Cramer seemed to recognize that the underwhelming financials and overall performance of the automotive division were not representative of the current state of affairs.
Instead, we’re seeing a company transition itself away from its early identity, essentially evolving like a caterpillar into a butterfly.
The narrative of the Earnings Call was simple: We’re not a car company, at least not from a birds-eye view. We’re an AI and Robotics company, and we are transitioning to this quicker than most people realize.
Tesla stock gets another analysis from Jim Cramer, and investors will like it
Tesla’s Q4 Earnings Call featured plenty of analysis from CEO Elon Musk and others, and some of the more minor details of the call were even indicative of a company that is moving toward AI instead of its cars. For example, the Model S and Model X will be no more after Q2, as Musk said that they serve relatively no purpose for the future.
Instead, Tesla is shifting its focus to the vehicles catered for autonomy and its Robotaxi and self-driving efforts.
Cramer recognizes this:
“…we got results from Tesla, which actually beat numbers, but nobody cares about the numbers here, as electric vehicles are the past. And according to CEO Elon Musk, the future of this company comes down to Cybercabs and humanoid robots. Stock fell more than 3% the next day. That may be because their capital expenditures budget was higher than expected, or maybe people wanted more details from the new businesses. At this point, I think Musk acolytes might be more excited about SpaceX, which is planning to come public later this year.”
He continued, highlighting the company’s true transition away from vehicles to its Cybercab, Optimus, and AI ambitions:
“I know it’s hard to believe how quickly this market can change its attitude. Last night, I heard a disastrous car company speak. Turns out it’s actually a robotics and Cybercab company, and I want to buy, buy, buy. Yes, Tesla’s the paper that turned into scissors in one session. I didn’t like it as a car company. Boy, I love it as a Cybercab and humanoid robot juggernaut. Call me a buyer and give me five robots while I’m at it.”
Cramer’s narrative seems to fit that of the most bullish Tesla investors. Anyone who is labeled a “permabull” has been echoing a similar sentiment over the past several years: Tesla is not a car company any longer.
Instead, the true focus is on the future and the potential that AI and Robotics bring to the company. It is truly difficult to put Tesla shares in the same group as companies like Ford, General Motors, and others.
Tesla shares are down less than half a percent at the time of publishing, trading at $423.69.

SpaceX secures win as US labor board drops oversight case
The NLRB confirmed that it no longer has jurisdiction over SpaceX.
SpaceX scored a legal victory after the National Labor Relations Board (NLRB) decided to dismiss a case which accused the company of terminating engineers who were involved in an open letter against founder Elon Musk.
The NLRB confirmed that it no longer has jurisdiction over SpaceX. The update was initially shared by Bloomberg News, which cited a letter about the matter it reportedly reviewed.
In a letter to the former employees’ lawyers, the labor board stated that the affected employees were under the jurisdiction of the National Mediation Board (NMB), not the NLRB. As a result, the labor board stated that it was dismissing the case.
As per Danielle Pierce, a regional director of the agency, “the National Labor Relations Board lacks jurisdiction over the Employer and, therefore, I am dismissing your charge.”
The NMB typically oversees airlines and railroads. The NLRB, on the other hand, covers most private-sector employers, as well as manufacturers such as Boeing.
The former SpaceX engineers have argued that the private space company did not belong under the NMB’s jurisdiction because SpaceX only offers services to “hand-picked customers.”
In an opinion, however, the NMB stated that SpaceX was under its jurisdiction because “space transport includes air travel” to get to outer space. The mediation board also noted that anyone can contact SpaceX to secure its services.
SpaceX had previously challenged the NLRB’s authority in court, arguing that the agency’s structure was unconstitutional. Jennifer Abruzzo, the NLRB general counsel under former United States President Joe Biden, rejected SpaceX’s claims. Following Abruzzo’s termination under the Trump administration, however, SpaceX asked the labor board to reconsider its arguments.
SpaceX is not the only company that has challenged the constitutionality of the NLRB. Since SpaceX filed its legal challenge against the agency in 2024, other high-profile companies have followed suit. These include Amazon, which has filed similar cases that are now pending.
