Tesla’s 4680 battery ramp may experience a “Death Valley” start, but it will be overcome: expert
To state that Tesla’s future lies in the success or failure of the 4680 battery is not an understatement. Without 4680 cells, Tesla’s efforts to create an affordable car at a price point beneath the Model 3 would likely be for naught. But if the company succeeds in ramping the production of its 4680 cells, Tesla could very well pave the way for electric vehicles to become the dominant form of personal transportation in the decades to come.
Getting there would not be easy. Tesla formally announced its 4680 battery project in September 2020, and since then, the company has been working hard to ramp the production of the next-generation cell. Tesla produced its one millionth 4680 cell in January. That’s a milestone on its own, but it does show that the company still has a long way to go before it can fully ramp its new battery.
Industry researcher Benchmark Mineral Intelligence estimates that one million 4680 cells are enough for just about 1,200 Model Ys. Tesla intends to produce far more than that per week in Gigafactory Texas alone.
Tesla’s 4680 cells are not designed like conventional batteries, and they are not made like traditional cells either. Tesla plans to use a new manufacturing technology called dry electrode coating, which was obtained from the company’s acquisition of Maxwell Technologies in 2019. Dry electrode manufacturing would allow Tesla to skip a conventional step in traditional battery production, which should lower costs significantly.
While Tesla acquired the technology, the innovations involved in the mass-production of 4680 cells using dry electrode coating are a massive challenge. Elon Musk has noted that the factory equipment for the process alone “doesn’t exist,” so they still have to be made.
Shirley Meng, a University of Chicago professor who previously worked with Maxwell, noted that Tesla’s 4680 battery efforts could change the industry. She also emphasized that Tesla’s challenges in mass-producing the next-generation battery would be immense. “He (Elon Musk) is changing the way how battery manufacturing is done. It’s really, really difficult to manufacture at a speed and at scale,” she said. She also stated that Tesla may have to experience a “Death Valley” start to scaling up the dry electrode process for 4680 cells.
She does, however, believe that Tesla would overcome these difficulties.
Other experts and longtime followers of the company seem to agree on the difficulty involved in developing and ramping a new type of battery cell. Caspar Rawles, chief data officer at Benchmark Mineral Intelligence, noted that fine-tuning the production equipment for battery production alone is an extremely long process, and one that challenges even the industry’s veterans. “There’s a very long process of fine-tuning the equipment before you can get to volume production. Battery production is hard, even hard for experienced suppliers,” he said.
This definitely seems to be the case with Panasonic. The Japanese tech conglomerate has been a longtime partner of Tesla, and it already operates Gigafactory Nevada with the EV maker. However, recent comments from Kazuo Tadanobu, the CEO of Panasonic’s energy division, revealed that even Panasonic had to take its time to develop its 4680 batteries. Tadanobu noted that Tesla has already deemed Panasonic’s 4680 cells viable for use, but mass production of the new batteries is still expected to start by the fiscal year ending in March 2024.
Tesla’s 4680 cells are expected to be used in vehicles like the Tesla Semi, the Cybertruck, and the company’s flagship supercar, the new Roadster. The next-generation batteries are also expected to be utilized in Tesla’s next big project, the production of an affordable $25,000 electric car.

Elon Musk confirms Tesla FSD V14.2 will see widespread rollout
Musk shared the news in a post on social media platform X.

Elon Musk has confirmed that Tesla will be implementing a wide rollout of Full Self-Driving (FSD) V14 with the system’s V14.2 update. Musk shared the news in a post on social media platform X.
FSD V14.1.2 earns strong praise from testers
Musk’s comment came as a response to Tesla owner and longtime FSD tester AI DRIVR, who noted that it might be time to release Full Self-Driving to the fleet because V14.1.2 has already become very refined.
“95% of the indecisive lane changes and braking have been fixed in FSD 14.1.2. I haven’t touched my steering wheel in two days. I think it’s time, Tesla AI,” the longtime FSD tester wrote.
AI DRIVR’s comment received quite a bit of support from fellow Tesla drivers, some of whom noted that the improvements that were implemented in V14.1.2 are substantial. Others also agreed that it’s time for FSD to see a wide release.
In his reply to the FSD tester, CEO Elon Musk noted that FSD V14’s wide release would happen with V14.2. “14.2 for widespread use,” Musk wrote in his reply.
Mad Max mode makes headlines
One of the key features that was introduced with FSD’s current iteration is Mad Max mode, which allows for higher speeds and more frequent lane changes than the previous “Hurry” mode. Videos and social media posts from FSD testers have shown the system deftly handling complex traffic, merging seamlessly, and maintaining an assertive but safe driving behavior with Mad Max mode engaged.
Tesla AI head Ashok Elluswamy recently noted in a post on X that Mad Max mode was built to handle congested daytime traffic, making it extremely useful for drivers who tend to find themselves in heavy roads during their daily commutes. With Musk now hinting that FSD V14.2 will go on wide release, it might only be a matter of time before the larger Tesla fleet gets to experience the notable improvements of FSD’s V14 update.

Multiple Tesla Cybercab units spotted at Giga Texas crash test facility
The vehicles were covered, but one could easily recognize the Cybercab’s sleek lines and compact size.

It appears that Tesla is ramping up its activities surrounding the development and likely initial production of the Cybercab at Giga Texas. This was, at least, hinted at in a recent drone flyover of the massive electric vehicle production facility in Austin.
Cybercab sightings fuel speculations
As observed by longtime Giga Texas drone operator Joe Tegtmeyer, Tesla had several covered Cybercab units outside the facility’s crash testing facility at the time of his recent flyover. The vehicles were covered, but one could easily recognize the Cybercab’s sleek lines and compact size. Tegtmeyer also observed during his flyover that production of the Model Y Standard seems to be hitting its pace.
The drone operator noted that the seven covered Cybercabs might be older prototypes being decommissioned or new units awaiting crash tests. Either scenario points to a ramp-up in Cybercab activity at Giga Texas, however. “In either case, this is another datapoint indicating production is getting closer to happening,” Tegtmeyer wrote on X, highlighting that the autonomous two-seaters were quite exciting to see.
Cybercab production targets
This latest sighting follows reports of renewed Cybercab appearances at both the Fremont Factory and Giga Texas. A test unit was recently spotted driving on Giga Texas’ South River Road. Another Cybercab, seen at Tesla’s Fremont Factory, appeared to be manually driven, suggesting that the vehicle’s current prototypes may still be produced with temporary steering controls.
The Tesla Cybercab is designed to be the company’s highest-volume vehicle, with CEO Elon Musk estimating that the autonomous two-seater should see an annual production rate of about 2 million units per year. To accomplish this, Tesla will be building the Cybercab using its “Unboxed” process, which should help the vehicle’s production line achieve outputs that are more akin to consumer electronics production lines.

Teslas in the Boring Co. Vegas Loop are about to get a big change
Elon Musk has a big update for Teslas that operate within the Boring Company’s Vegas Loop.

Tesla vehicles operating in the Boring Company’s Vegas Loop are about to get a big change, CEO Elon Musk said.
In Las Vegas, the Boring Company operates the Vegas Loop, an underground tunnel system that uses Teslas to drop people off at various hotspots on the strip. It’s been active for a few years now and is expanding to other resorts, hotels, and destinations.
Currently, there are stops at three resorts: Westgate, the Encore, and Resorts World. However, there will eventually be “over 100 stations and span over 68 miles of tunnel,” the Vegas Loop website says.
The Loop utilizes Tesla Model 3 and Model Y vehicles to send passengers to their desired destinations. They are currently driven using the Full Self-Driving suite, but they also have safety drivers in each vehicle to ensure safety.
Tesla Cybertruck rides are crucial for Vegas Loop expansion to airport
Tesla and the Boring Company have been working to remove drivers from the vehicles used in the Loop, but now, it appears there is a set timeline to have them out, according to CEO Elon Musk:
The Tesla cars operating in The Boring Company tunnels under Las Vegas will be driverless in a month or two https://t.co/mX4nNrJui9

Musk says the Boring Co. will no longer rely on safety drivers within the Teslas for operation. Instead, Tesla will look to remove the safety drivers from the cars within the next month or two, a similar timeline for what Musk believes the Robotaxi platform will look like in Austin.
In Texas, as Robotaxi continues to operate as it has since June, there are still safety monitors within the car who sit in the passenger’s seat. They are there to ensure a safe experience for riders.
When the route takes the vehicle on the highway, safety monitors move into the driver’s seat.
However, Tesla wants to be able to remove safety monitors from its vehicles in Austin by the end of the year, Musk has said recently.
In early September, Musk said that the safety monitors are “just there for the first few months to be extra safe.” He then added that there “should be no safety driver by end of year.”
The safety driver is just there for the first few months to be extra safe.
Should be no safety driver by end of year.
