Tesla’s electric cars are already among the safest vehicles on the road today with their impressive safety ratings. But even the best cars still have room for improvement, and one can count on Tesla to be the manufacturer that will do what it can to make its already-safe vehicles even safer. An example of this could be found in a recently published patent that describes a “crash can” that can help protect occupants better in the event of a collision.

The patent, titled “ADVANCED THIN-WALLED STRUCTURE FOR ENHANCED CRASH PERFORMANCE” describes a specific design for a “crash can,” a thin-walled metal structure that is built into the crash zones of a vehicle. These metal structures are built to absorb the energy of an impact, and are designed to deform in a stable manner during events such as a crash. Crash cans are typically a square, single-cell tube directly mounted to the front of the frame of the vehicle. 

Tesla’s crash can patent takes the same concept but raises it up a couple of notches higher. Instead of using a simple square, single-cell tube, Tesla’s patent describes a “multi-cell structure that includes at least four hollow cuboids.” The four walls of the hollow cuboids meet at 90-degree angles and at least two of the cuboids share a wall. Tesla describes its design in the section below. 

“In some embodiments a crash can for a vehicle includes a multi-cell structure that includes a hollow cuboid and four hollow isosceles trapezoidal prisms. The hollow cuboid has four walls and the four hollow isosceles trapezoidal prisms each have a long base, a short base, and two legs. The four hollow isosceles trapezoidal prisms are arranged around the hollow cuboid such that the long base of each hollow isosceles trapezoidal prism shares one of the walls of the hollow cuboid.”

This updated design, while seemingly a minor change, actually improves the safety of a vehicle during a crash. According to Tesla, the crash can design in its recently-published patent provides a more stable deformation process. This increases the amount of energy that can be absorbed in a collision. 

“One advantage of the various embodiments of the crash cans disclosed herein is that the multi-cell structure of the crash cans provides a more stable form of plastic deformation when the crash can is subject to the force of a collision relative to a single cell (tube) structure. Further, the various geometries described herein may further provide more stable plastic deformation relative to conventional geometries. As described herein, plastic deformation is the process of absorbing energy when the crash can is subject to a collision. Various exemplary crash cans provided herein increases plastic deformation, and thus the amount of energy absorbed, by increasing the probability that the crash cans buckle in a progressive manner. Thus, the multi-cell structure of the exemplary crash cans increases the probability that when subjected to axial force the crash cans will buckle in a stable top-down, progressive folding of the structure.

“Increasing plastic deformation in this manner grants the multi-cell crash can several advantages. For example, increasing plastic deformation in turn increases the amount of energy that will be absorbed during a collision, resulting in lower deceleration for the occupant(s) and critical components of a vehicle involved in a collision. This, in turn, results in an overall safer experience for the occupant(s) and critical components, providing for a lower chance of injury or damage. Additionally, increasing the probability that the multi-cell crash can buckles in a stable manner increases the predictability of how the crash can will react when subject to a collision, which in turn increases the predictability of how the rest of the vehicle will react. This allows for greater predictability of what an occupant will experience and allows for more precise planning on how to keep the occupant safe.”

Among the carmakers in the auto segment today, Tesla is arguably the most obsessive when it comes to its vehicles’ safety. Each one of Tesla’s electric cars has performed well in crash tests, with the Model X SUV proving to be near-impossible to topple, and the Model 3 acing the safety tests of the NHTSA, Euro NCAP, ANCAP, and even the IIHS. With improvements such as those described in its recently-published “crash can” patent, Tesla’s electric cars today, as well as its upcoming vehicles, could prove even safer.

Tesla gets price target increase on Wall Street, but it’s a head-scratcher

Delaney’s price target on Tesla shares went up to $395 from $300. Currently, Tesla is trading between $420 and $430, making the new price target from Goldman Sachs a bit of a head-scratcher.

Tesla (NASDAQ: TSLA) received a price target increase from a Wall Street analyst today, who noted in his report that the company’s shares could rise or fall based on its execution in robotics and autonomy.

However, the price target boost still fell below Tesla’s current trading levels.

Mark Delaney of Goldman Sachs said in a note to investors today that Tesla has a significant opportunity to solidify itself as one of the stable and safe plays in the market if it can execute on its two key projects: humanoid robots and autonomy.

In the note, Delaney said:

“If Tesla can have [an] outsized share in areas such as humanoid robotics and autonomy, then there could be upside to our price target.”

Delaney’s price target on Tesla shares went up to $395 from $300. Currently, Tesla is trading between $420 and $430, making the new price target from Goldman Sachs a bit of a head-scratcher.

He went on to say that Tesla could also confront outside factors that would limit the stock’s ability to see growth, including competition and potentially its own lack of execution:

“…although if competition limits profits (as is happening with the ADAS market in China) or Tesla does not execute well, then there could be downside.”

The note is an interesting one because it seems to point out the blatantly obvious: if Tesla performs well, the stock will rise. If it doesn’t, the stock price will decline.

We discussed yesterday in an article that Tesla is one of the few stocks out there that does not seem to be influenced by financials or anything super concrete. Instead, it is more influenced by the narrative currently surrounding the company, rather than the technicals.

Tesla called ‘biggest meme stock we’ve ever seen’ by Yale associate dean

Tesla’s prowess in robotics and autonomy is strong. In robotics, it has a very good sentiment following its Optimus project, and it has shown steady improvement with subsequent versions of the robot with each release.

On the autonomy front, Tesla is expanding its Robotaxi platform in Austin every few weeks, and also has a sizeable geofence in the Bay Area. Its Full Self-Driving suite is among the most robust in the world and is incredibly useful and accurate.

The company can gain significant value if it continues to refine the platform and eventually rolls out a driverless or unsupervised version of the Full Self-Driving suite.

Tesla addresses door handle complaints with simple engineering fix

“We’ll have a really good solution for that. I’m not worried about it.”

Tesla is going to adjust one heavily scrutinized part of its vehicles after recent government agencies have launched probes into an issue stemming from complaints from owners.

Over the past few days, we have reported on the issues with Tesla’s door handle systems from both the Chinese and American governments.

In China, it dealt with the Model S, while the United States’ National Highway Traffic Safety Administration (NHTSA) reported nine complaints from owners experiencing issues with 2021 Model Ys, as some said they had trouble entering their car after the 12V battery was low on power.

Bloomberg, in an interview with Tesla Chief Designer Franz von Holzhausen, asked whether the company planned to adjust the door handle design to alleviate any concerns that regulatory agencies might have.

Regarding the interior latch concerns in the United States:

  • Von Holzhausen said that, while a mechanical door release resolves this problem, Tesla plans to “combine the two” to help reduce stress in what he called “panic situations.”
  • He also added that “it’s in the cars now…The idea of combining the electronic and the manual one together in one button, I think, makes a lot of sense.” Franz said the muscle memory of reaching for the same button will be advantageous for children and anyone who is in an emergency.

Regarding the exterior door handle concerns in China:

  • Von Holzhausen said Tesla is reviewing the details of the regulation and confirmed, “We’ll have a really good solution for that. I’m not worried about it.”

The new Model Y already has emergency mechanical door release latches in the back, but combining them in future vehicles seems to be an ideal solution for other vehicles in Tesla’s lineup.

It will likely help Tesla avoid complaints from owners about not having an out in the event of a power outage or accident. It is a small engineering change that could be extremely valuable for future instances.

Elon Musk calls out viral claim of 10,000 Tesla Optimus deal: “Fake”

For now at least, Tesla seems determined to focus on the development of Optimus V3.

Elon Musk has provided some clarification to recent reports suggesting that PharmAGRI, a US pharmaceutical and agricultural infrastructure company, is looking to deploy 10,000 Optimus robots for its operations.

Musk posted his clarification on social media platform X.

Alleged Optimus purchase

Recently, reports emerged stating that PharmAGRI Capital Partners will be tapping into Tesla’s humanoid robots for its operations. The firm claimed that it had executed a Letter of Intent with Tesla to deploy up to 10,000 Optimus Gen 3+ humanoid robots across its SuperPharm and CEA facilities. This should allow the company to automate its labor and ensure diversion control.

A comment from Lynn Stockwell, Chairwoman & CEO, suggested that the company really was partnering with Tesla. “With Tesla robotics powering our facilities and DEA-licensed infrastructure in place, we can scale with precision, meet federal sourcing mandates, and deliver therapies that are compliant, secure, and American-made,” she said. 

Elon Musk clariies

News of PharmAGRI’s Optimus claims quickly spread on social media, though some Tesla watchers argued that it seemed unlikely that the EV maker will commit two legions of Optimus robots to a rather unknown company this early. Some pointed out that Tesla typically commits to high-profile customers to test its early products, such as PepsiCo with the Tesla Semi.

Photos from PharmAGRI’s website depicting Tesla Optimus bots, as well as the rather basic look of the website itself, also brought more reservations to the company’s claims. Ultimately, Elon Musk weighed in on the matter, responding to a post about PharmAGRI’s Optimus-filled webpage. Musk was quick and direct, simply stating, “Fake.”

Elon Musk’s comments were quite unsurprising considering that Optimus is still very much in active development, and thus, it is quite unlikely that the company is already taking orders or even Letters of Intent from potential customers at this time. For now at least, Tesla seems determined to focus on the development of Optimus V3, which Musk has noted will be “sublime.”
