A high-speed accident involving a Model 3 crashing into a pole recently provided an impressive look at the fire-resistant capabilities of Tesla’s batteries. Despite major damage to the vehicle and two of the battery modules being breached from the violent impact, none of the Model 3’s 2170 cells burst into flame. 

Insights from the Model 3 crash were shared recently at the r/TeslaMotors subreddit by u/Yaro_S, who rebuilds Tesla cars. Writing about the Model 3, the electric car enthusiast admitted that he didn’t expect the damage to the vehicle to be as serious as it was. A look at the damaged vehicle suggested that the Model 3 hit a pole at high-speed, forcing the front electric motor into the driver side’s footwell and puncturing the battery pack in the process.

Images of the vehicle as it was being parted out showed that the crash had damaged two of the Model 3’s battery modules. Interestingly, and as observed by the rebuilder, none of the battery cells caught fire despite the extensive damage from the high-speed accident. Interestingly, one cell showed signs that it got to a very hot temperature, but instead of burning, the cell seemed to have started melting instead. 

The rebuilder noted that the damage to the Model 3’s battery pack was the worst he has seen in a Tesla to date, exceeding a previous project that involved a pack that was punctured from the bottom. Overall, while the damage to the vehicle was quite chilling, the r/TeslaMotors subreddit community member remarked that he came away extremely impressed at the fire-resistant capabilities of Tesla’s batteries.

It is no exaggeration to state that the backbone of Tesla’s entire business lies in its battery technology, from its electric cars like the Model 3 to its energy storage products like the recently-announced Megapack. It is then unsurprising to see Tesla dedicate a significant part of its efforts in constantly improving its batteries. This was mentioned previously by Automotive President Jerome Guillen, who noted in an interview that the design of Tesla’s battery cells are always in a process of improvement. “The design of the cell is not frozen. It evolves, and we have a nice roadmap of technology improvements for the coming years,” Guillen said. 

Some of Tesla’s improvements to its batteries have been teased in previously published patents. One of these, which was published last July, involved a system that allows the company to isolate the damage caused by failed cells to specific sections of a battery pack, allowing the company to save the integrity of functional battery cells that are otherwise undamaged.

A radical new patent from Tesla has provided a potential hint at a technology that the electric vehicle maker can utilize to meet the new Roadster’s ambitious 0-60 mph targets. If the technology outlined in the patent does come into fruition, it could help the Roadster stay planted on the ground even as it executes extremely rapid and demanding driving maneuvers.

The Roadster’s 0-60 mph time

When the new Roadster was announced way back in late 2017, Elon Musk stated that the upcoming vehicle would have a 0-60 mph time of 1.9 seconds. This was impressive, but the new Roadster has become so late that this metric is no longer industry-leading. Even Tesla’s own Model S Plaid, a large and heavy family sedan, can now hit a 0-60 mph time in 1.99 seconds, all for a price that starts just under $100,000.

Back in February 2024, Elon Musk stated that Tesla “radically increased the design goals for the new Tesla Roadster.” He stated that there will never be another car like the Roadster, if it could even be called a car. Musk also added that Tesla is now looking to achieve a 0-60 mph time in less than one second with the new Roadster, though this would be the “least interesting part” of the vehicle.

Inasmuch as a 0-60 mph time of 1 second or less sounds insane, these figures are achieved by vehicles like top fuel dragsters, which could accelerate well under 1 second. Of course, these vehicles are specialized machines and not road legal by any means, so the Roadster would still be in a class of its own if Tesla does manage to achieve a sub-1-second 0-60 mph time.

Tesla’s new aero patent 

A new patent from Tesla has now outlined a technology that could be a perfect fit for the upcoming all-electric supercar. Tesla’s patent is for a multi-mode active aero system that uses fans and deployable skirts to generate controllable downforce. This should pave the way for optimal vehicle grip and performance across varying conditions, from the track to the drag strip.

Tesla describes the patent’s technology as follows: 

“The system operates by creating bounded (e.g., sealed or partially-sealed) regions beneath the vehicle through the selective deployment of skirts that interact with the ground surface. Fans positioned in airflow pathways that extend to these bounded regions generate low pressure within these areas by extracting air, creating downforce that enhances vehicle grip and stability (e.g., by creating a vacuum, or partial vacuum in the bounded regions).”

If Tesla could indeed create a fully bounded region under the new Roadster using the technology outlined in the patent, the company could all ensure that the all-electric supercar always has perfect traction when it launches. It could also help the vehicle handle better in corners, which would be useful if the Roadster were to attempt setting records in tracks such as the Nurburgring.

Tesla’s new Robotaxi geofence shape is an FU by Elon Musk to the competition

Maybe it’s all pareidolia. But maybe it’s not. After all, Tesla embraced the first geofence expansion for what it appeared to be.

Tesla expanded its Robotaxi geofence in Austin once again early Sunday morning. The new shape seems to be somewhat of a proverbial, and potentially literal, middle finger to the competition.

If you thought the first expansion was a message to the competition and doubters of the company’s ride-hailing service, you probably will believe the second expansion is an even stronger gesture.

Tesla’s first expansion did not go unnoticed, as its shape was particularly recognizable. The company has always operated with a sense of humor, and it embraced what it did. Some, including me, took it as a message to competitors: We can expand in any direction, in any size, at any time. We’ll prove it.”

They picked a shape and went with it:

Tesla’s Robotaxi expansion wasn’t a joke, it was a warning to competitors

It is evident that Tesla is keeping its humor up to continue to show a few things. The first is that it really can expand in any direction it wants and that’s how it is choosing to show it.

The second, well, maybe it’s an edgier way to show doubters that it is really executing on Robotaxi:

Maybe it’s all pareidolia. But maybe it’s not. After all, Tesla embraced the first geofence expansion for what it appeared to be. This might be a similar occurrence, and it might be sending another message to the competition, critics, and doubters.

The expansion was a near-doubling of the geofence Tesla offered previously. After the initial geofence covered just about 20 square miles, Tesla was able to more than double it to 42 square miles with the first growth. This new geofence shape was just under double, and is about 80 square miles.

Tesla’s rapid expansion has impressed many, especially considering the service area has roughly doubled for the second time in well under two months. The Robotaxi service was first offered on June 22.

Tesla (NASDAQ: TSLA) executed what Wedbush’s Dan Ives called “a must” this morning as it finalized a new pay package for its CEO Elon Musk.

The move helped give Musk his first meaningful compensation at Tesla since 2017, when the company offered a pay package that was based on performance and proven growth. That package was approved by shareholders on two separate occasions, but was denied to Musk both times by the Delaware Chancery Court.

On Monday, Tesla announced on X that it had created a new package that would give 96 million shares of restricted stock to Musk to compensate him for the “immense value generated for Tesla and all our shareholders.”

The details of the pay package are designed to retain Musk, who has voiced some concerns about his control of Tesla, as “activist shareholders” have used lawsuits to disrupt the previously approved package.

Tesla rewards CEO Elon Musk with massive, restricted stock package

Ives says Musk’s retention is ‘a must’

Ives said in a note to investors on Monday that with the raging AI talent war that Tesla made a smart move by doing what it could to retain Musk.

He wrote:

“With the AI talent war now fully underway across Big Tech, we believe this was a strategic move to keep TSLA’s top asset, Musk, would stay focused at the company with his priority being to bolster the company’s growth strategy over the coming years. With this interim award increasing Musk’s voting rights upon this grant, which Musk honed in on and mentioned was increasingly important to incentivize him to stay focused on the matters at hand, this was a strategic move by the Board to solidify Musk as CEO of Tesla over the coming years with this framework for Musk’s pay package and greater voting control removing a major overhang on the story.”

He went on to say:

“While the groundwork is now in place for the next few years, it will be critical for the Tesla Board of Directors to get this long-term compensation strategy in place prior to the company’s November 6th shareholder meeting which would address the elephant in the room and remove a significant overhang on the stock.”

Wedbush maintained its Outperform rating and its $500 price target on the stock.
