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?”

The full patent for Tesla’s Armored Glass is available below.

Tesla firmware shows new Model Y seat configuration is coming

Tesla could be adding another seating configuration beside the seven-seater to the Model Y lineup later this year.

Tesla firmware has been a great place for some to reveal what the company has in the pipeline, and a new seating configuration for the best-selling Model Y looks to be on the way.

Last week, we reported that Tesla was already hinting toward a 7-seater configuration of the Model Y in a promotional email it sent to those on its contact list.

However, firmware revealed by Tesla hacker greentheonly is showing that a new seating configuration is on the way — a six-seater:

Green says the configuration would not be available in China-only, and will be potentially for sale in other markets as well.

The six-seat and seven-seat configurations of the Model Y were available in the Legacy version of the vehicle, but were met with mixed reviews, as many complained about the lack of legroom in the third row.

This was something that was a real concern for many of those owners who needed something larger than the traditional five-seat variant, but did not want to buy the much more pricey Model X.

We’ve covered the size of that third row on several occasions.

Some owners even took the idea of having a seven-seater into their own hands:

Tesla did not explicitly announce a six-seater configuration of the Model Y, but Lars Moravy, the company’s VP of Vehicle Engineering, said the seven-seater would come to production later in 2025.

Tesla confirms massive hardware change for autonomy improvement

Tesla has confirmed that a recent change made to some of its recently refreshed vehicles is, in fact, a strategy it will use to improve its suite as it continues to work toward autonomy.

Tesla has confirmed that a recent change made to some of its recently refreshed vehicles is, in fact, a strategy it will use to improve its suite as it continues to work toward autonomy.

Tesla first introduced a front-facing camera on the front bumper with the Cybertruck.

Then, the Model Y “Juniper” received the hardware update. The Model S and Model X both received the front-facing camera with its latest update, which was officially revealed last week.

Tesla used new language with the release of the front-facing cameras on the Model S and Model X, confirming they will assist with several things, including “using Autopilot and Actually Smart Summon capabilities”:

“Enhanced visibility when parking or using Autopilot and Actually Smart Summon capabilities.”

This tiny feature on the new Tesla Model Y is perhaps its biggest addition

This is the first time Tesla has used this sort of language, as it was a completely different description with the launch of the new Model Y in January.

When Tesla launched this vehicle, it said the front bumper camera “provides a wider field of view for automatic assisted driving and advanced Smart Summon.”

Tesla switched from using cameras and sensors to only cameras with the launch of Tesla Vision several years ago. The company’s utilization of cameras comes from Tesla’s belief that Ultrasonic Sensors (USS) are not needed for self-driving efforts:

“Along with the removal of USS, we simultaneously launched our vision-based occupancy network – currently used in Full Self-Driving (FSD) (Supervised) – to replace the inputs generated by USS. With today’s software, this approach gives Autopilot high-definition spatial positioning, longer range visibility and the ability to identify and differentiate between objects. As with many Tesla features, our occupancy network will continue to improve rapidly over time.”

CEO Elon Musk has said that sensors were only a crutch and that self-driving would be solved through the use of cameras:

“When your vision works, it works better than the best human because it’s like having eight cameras, it’s like having eyes in the back of your head, beside your head, and has three eyes of different focal distances looking forward. This is — and processing it at a speed that is superhuman. There’s no question in my mind that with a pure vision solution, we can make a car that is dramatically safer than the average person.”

Tesla features used to flunk 16-year-old’s driver license test

A license examiner in New Jersey confused one standard feature of Teslas as a way a 16-year-old excelled through his driver’s test. He failed him because of it.

In what is becoming a more common occurrence, a few Tesla features were used to flunk a 16-year-old who took his driver’s license test in New Jersey.

It is not the first time this has happened, as we have reported on several instances of this in the past, both in the U.S. and other countries in the world.

It is evidence that some officials are not caught up in the technology and innovation occurring in the automotive market, some of which is not necessarily exclusive to Tesla, but is included in each of its models, unlike other companies.

Lochlan Keefer, a New Jersey resident, showed up to his driver’s test with his dad, James, in their 2022 Tesla Model Y. However, the test did not go according to plan, according to the examiner who rode along for the test with Lochlan. They accused him of using parking and “stopping assistance” to go through the test.

The examiner cited the following as the reason for failure:

“Had the parking and stopping assistance on never stepped on the brake to stop his self let the vehicle stop it self.”

James said to NJ.com that they do not subscribe to Tesla’s Full Self-Driving suite, which includes things like Autopark, Navigate on Autopilot, and Autosteer on City Streets. These are a few of the things that have been used as reasoning to fail drivers in tests. Lochlan’s was a case of regenerative braking, which is standard on all vehicles, and Autopark:

“The examiner accused my son of using driver assistance features simply because he parallel parked smoothly on the first try. He was specifically accused of using paid parking-assist and driving features, which we do not subscribe to.”

It sounds as if the examiner may have confused the braking mishap for Tesla’s regenerative braking, which slows the vehicle when the accelerator is not pressed. The energy is then stored back in the battery to help with range.

The examiner failed Lochlan, and James asked if he could take the test again if they disabled the regenerative braking for the exam. The examiner said Lochlan would have to wait two weeks. A supervisor came out and backed the examiner, but James said the policy the DMV claimed the Keefer’s violated was nowhere to be found:

“I asked them to show me the policy they claimed we were violating. They couldn’t find it and they couldn’t cite it. When I showed them the policy, they refused to read it.”

The report states that drivers in California and Arizona have also been subjected to failures on their driving tests due to confusion over Teslas and their driver assistance features.
