A chairman from China-based battery giant Contemporary Amperex Technology Co. Limited (CATL) recently cast doubt on Tesla’s 4680 battery cell, saying that he didn’t think it would be successful in the long run.
In a conversation earlier this year, CATL Chairman Robin Zeng told Elon Musk that the cylindrical 4680 battery “is going to fail and never be successful,” according to a report from Reuters this week. Zeng made the statements to Musk in a meeting with the Tesla CEO on his Beijing visit in April, and the chairman also said that the Tesla CEO was better equipped to handle other technologies than battery cells.
“We had a very big debate, and I showed him,” Zeng said. “He was silent. He doesn’t know how to make a battery. It’s about electrochemistry. He’s good for the chips, the software, the hardware, the mechanical things.”

Tesla’s 4680 battery cell and CATL licensing
In September, Tesla announced that it had produced its 100 millionth 4680 battery cell at Gigafactory Texas, after reaching 50 million units in June. The company is also in the process of expanding its Gigafactory Nevada to add a dedicated 4680 cell production facility, expected to ramp up to 500 GWh in the long term.
The report also highlights a licensing deal Tesla has with CATL for technology related to producing batteries in Nevada, expected to officially launch in 2025, according to a person with knowledge of the matter who spoke to Reuters under the condition of anonymity.
Zeng on FSD Supervised and Musk’s promise timelines
In addition to discussing battery technology, the chairman said that he and Musk talked about the company’s focus on autonomy, adding that he agrees with Tesla’s overall approach to the topic. Unlike other companies that are developing self-driving systems, Tesla’s Supervised Full Self-Driving (FSD) only utilizes cameras as sensors, rather than using multiple layers of different redundant technologies.
“He’s all in,” Zeng told Reuters regarding Musk and Tesla’s FSD strategy in a statement earlier this month. “I think it’s a good direction.”
Despite his support for the company’s approach to FSD Supervised, Zeng also noted that he thinks Musk tends to set unrealistic timelines for new vehicle technologies, and he even asked the Tesla CEO during the April conversation, saying two-year timelines may as well be “infinity.”
“His problem is overpromising. I talked to him,” the chairman added. “Maybe something needs five years. But he says two years. I definitely asked him why. He told me he wanted to push people.”
Musk has addressed criticisms of his timelines before, pointing to his optimism as a necessary part of his accomplishments.
While certainly not perfect, my batting average for most predictions is quite good.
My schedule optimism, without which I probably wouldn’t even have tried to do many endeavors, gets the best of me sometimes, but I always deliver in the end.— Elon Musk (@elonmusk) December 30, 2023
“Now, admittedly I’m a little optimistic sometimes,” Musk said during this year’s Annual Shareholders Meeting. “You know, I don’t have a complete lack of self awareness. But if I wasn’t optimistic, this wouldn’t exist this factory wouldn’t exist.”
The CEO later went on to add that he believes he’s been “pathologically optimistic from birth.”
CATL hopes for U.S. factory under Trump
CATL also told Reuters that it would build a U.S. production facility if President-elect Donald Trump would allow it.
“Originally, when we wanted to invest in the U.S., the U.S. government said no,” Zeng said. “For me, I’m really open-minded.”
“I do hope that in the future they are open to investments,” the chairman added.
In August, Trump expressed that he would be open to Chinese companies building factories in the U.S., despite the country’s recent passage of a 100-percent tariff on electric vehicle (EV) imports.
“We’re going to give incentives, and if China and other countries want to come here and sell the cars, they’re going to build plants here, and they’re going to hire our workers,” Trump said in a statement to the publication in August.

Tesla Cybercab tests seem to be ramping up again
Elon Musk has stated that he expects the company to achieve a run rate of 2 million Cybercabs annually.

Tesla seems to be ramping the tests of its autonomous two-seater, the Cybercab, once more. This was hinted at in recent drone footage from both the Fremont Factory and Gigafactory Texas.
The fresh sightings of the Cybercab in the Fremont Factory and Giga Texas have renewed conversations about the vehicle potentially being built with manual controls today.
Fresh Cybercab tests
As noted by longtime drone operator Joe Tegtmeyer on social media platform X, he recently spotted a Cybercab driving on Giga Texas’ South River Road to the West side. Interestingly enough, the longtime Giga Texas watcher noted that this was the first Cybercab that he had seen conducting road tests in a while.
Over in the Fremont Factory, another Cybercab was spotted driving around the facility’s testing area. Similar to the Cybercab in the Giga Texas sighting, the vehicle that was spotted in the Fremont Factory seemed to be manually driven, at least based on the way it was being steered. This behavior has incited speculations among Tesla watchers that current Cybercab test units have manual controls, unlike their production version, which would have no steering wheel or pedals.
Cybercab production preparation
The sightings of Cybercabs around the Fremont Factory and Giga Texas bode well for the vehicle’s development and impending production. It does, if any, complement reports that Tesla has been busy setting up production equipment for Giga Texas’ Cybercab production line. At the same time, drone footage around the Giga Texas complex has also revealed that Tesla is stockpiling some Cybercab castings, a likely sign that initial test production of the vehicle might soon begin.
The Cybercab is expected to be Tesla’s highest volume vehicle, with CEO Elon Musk stating that he expects the company to achieve a run rate of 2 million Cybercabs annually. He also mentioned that the Cybercab will be easy to produce thanks to its Unboxed manufacturing process, so much so that its production would resemble a high-speed consumer electronics line instead of an automotive assembly line.

Tesla FSD gets first rave reviews from media outlets in Japan
As per the publication, FSD demonstrated excellent situational awareness and smooth control, at times even performing better than a human driver.

Tesla FSD may continue to get flak from mainstream media outlets in the United States, but in other countries such as Japan, Full Self-Driving is being welcomed with much appreciation.
This is, at least, as per recent reviews from domestic media outlets that have tried out the capabilities of FSD on real-world roads.
FSD gets recognition
FSD was recently reviewed by Japanese news outlet Nikkei, which experienced the system’s capabilities in Tokyo’s metropolitan area. As per the publication, FSD demonstrated excellent situational awareness and smooth control, at times even performing better than a human driver. FSD was also credited for properly reacting to sudden, unexpected things on the road.
As per the FSD review, for example, a bicyclist suddenly came barreling into a crosswalk at high speed from the Tesla’s blind spot. The vehicle recognized the cyclist immediately and responded in a safe and proper manner, prompting the reviewer to exclaim “Wow!” And when a vehicle ahead of the Tesla started backing up to perform a turnaround on a narrow street unexpectedly, FSD smoothly halted to avoid a collision. Overall, the reviewer noted that during the 30-minute drive, the Tesla Model 3 running FSD did not require a single intervention.
FSD’s impending Japan rollout
FSD is not yet rolled out in Japan, but the country seems to be paving the way for FSD to be released in the country. Just recently, reports emerged stating that Japan’s Land, Infrastructure, Transport and Tourism Ministry has allowed artificial intelligence-powered vehicles to be retrofitted with a software update that could enable the activation of their self-driving features.
In a post on X, Tesla Board Member Hiro Mizuno noted that this decision is no small matter as it could pave the way for a smooth rollout of features like FSD to Tesla consumers in Japan. “The Ministry of Land, Infrastructure, Transport and Tourism’s decision to allow retrofitting of autonomous driving through software updates is significant. Currently, Tesla is the only manufacturer actively pursuing this… this decision will make it easier for all manufacturers to introduce autonomous driving in Japan,” the former Tesla Board member wrote in his post.

Tesla extends Model Y L delivery estimates to December 2025
This suggests that the six-seat, all-electric crossover SUV has become fully sold out for both October and November.

Tesla’s new extended-wheelbase Model Y L seems to be getting a lot of traction in China. As per Tesla China’s order page, the estimated delivery date for new vehicle orders is now listed as December 2025.
This suggests that the six-seat, all-electric crossover SUV has become fully sold out for both October and November. This bodes well for the vehicle, considering that it is currently the most expensive trim of the Model Y available in China.
Model Y L demand
Launched in August and first delivered in September, the Model Y L seems to be gaining momentum among Chinese EV buyers who are looking for added space and flexibility in their family vehicles. The Model Y L features a six-seat configuration with a very comfortable second row and a third row that fits regular-sized adults. This makes it a good all-around family car.
While the initial weeks of Model Y L insurance registrations were quite low, the vehicle’s registrations have been picking up in recent weeks. As per recent reports, the Model Y L’s volumes have been growing so much that the vehicle has helped boost Tesla China’s wholesale numbers in September. Even more Model Y L units would likely be registered this October.
Strong local momentum
The Model Y L’s sellout streak highlights Tesla China’s continued strength in the world’s most competitive EV market. With new orders now having an estimated delivery date of December, it seems all but certain that Tesla China would be selling every Model Y L it produces this fourth quarter. This could then help bolster the company’s numbers this Q4 2025.
The Model Y L is only being sold in China for now, though the vehicle’s features and size would actually make it very competitive in markets where larger family EVs are in high demand. Priced from RMB 339,000 ($47,180), the crossover offers a blend of performance, practicality, and value that has seemingly struck a chord with consumers, both in China and potentially, even abroad.
