Tesla Giga Berlin’s 4680 supply won’t start in Germany, and it was never supposed to
Tesla’s plans for the initial battery needs and efforts at Giga Berlin were answered in late 2020 by the automaker during the Q3 Earnings Call. While things tend to change on a somewhat regular basis as far as plans for something as large as a vehicle manufacturing plant, Tesla knew that its initial battery fulfillment plans likely wouldn’t come from the planned Giga Berlin 4680 cell production lines. Instead, Tesla will rely on its Kato Road facility in Northern California, where the development and manufacturing of a new, revolutionary electric vehicle battery is taking place. Tesla also plans to utilize strong relationships with its battery cell manufacturers to solve supply concerns during Giga Berlin’s early production dates.
Concerns regarding Tesla’s planned timeline for Giga Berlin have arisen over the past several days, especially after a German media outlet said that CEO Elon Musk was extending the beginning of the German plant’s EV production efforts to January 2022. While the Giga Berlin timeline remains uncertain as far as the exact starting date, those close to the situation, including Brandenburg Economic Minister Jörg Steinbach, told Teslarati yesterday that production should begin in late Summer or early Fall 2021.

The concerns about Tesla Giga Berlin’s initial production date started to appear around the same time that reports began to surface about Tesla adding the 4680 battery manufacturing unit plans to its application. German regulators take a deliberate and somewhat extended time for large projects, as so many different factors are considered before anything is given ultimate approval. Some indicated that this extensive regulatory process would delay the production efforts altogether. Still, local sources in Germany have clarified that this only prolongs the project altogether and doesn’t have much of an effect on the start of production. The project will just take longer to complete considering Tesla added another element to the Giga Berlin offensive.
As previously mentioned, the addition of the 4680 line to the application likely caused confusion over whether the Tesla Giga Berlin production lines would activate on time. 4680 production at Berlin will not begin before or at the same time as Tesla’s vehicle production at the German plant. However, Tesla’s plans were never to have the Berlin 4680 lines handle the initial vehicle production at the plant. Tesla originally planned for the Kato Road 4680 lines to supply Giga Berlin with cells when they are available.
Drew Baglino, Tesla’s Senior Vice President of Powertrain and Energy Engineering, said during the Q3 2020 Earnings Call:
“We will incorporate 4680 design solutions into many applications in time across both energy and vehicle, and we can use our pilot production facility in Fremont to support the new factory in Berlin as it ramps.”
Additionally, Tesla’s battery suppliers are being called upon to assist in the initial efforts at Giga Berlin.
Musk announced during the most recent Q1 2021 Earnings Call that Tesla is about 12-18 months away from volume production of 4680 cells. While Tesla may be slightly behind schedule regarding the production of the new 4680 battery, there is no indication that it will delay Giga Berlin’s production altogether. In fact, Musk also acknowledged that its suppliers, who Tesla shares “very strong partnerships” with would be called upon to supply cells “as much as they possibly can.”
Musk said:
“…It appears as though we’re about 12 — probably not more than 18 months away from volume production of the 4680. Now at the same time, we are actually trying to have our cell supply of partners ramp up their supply as much as possible. So this is not something that is to the exclusion of suppliers. It is in conjunction with suppliers. So we want to be super clear about that. This is not about replacing suppliers. It is about supplementing the suppliers. So…and we have a very strong partnership with CATL, with Panasonic and LG. And we would…our request to our strategic partners for cell supply is, please make us…please supply us with as much as you possibly can. Provided the price is affordable, we will buy everything that they can make.”
This includes CATL, a Chinese battery producer who manufactures LFP cells for the Standard Range+ Model 3 at Giga Shanghai. CATL began the construction of a cell manufacturing facility in Germany in 2019. LG Chem also started the construction of an EV battery cell manufacturing facility in Poland in 2017, which could be used to supplement Tesla’s battery efforts in Germany. These suppliers have both assisted Tesla with cells in the past, and these companies will likely supplement Tesla’s needs at Giga Berlin, as Musk requested during the Q1 2021 Earnings Call.
Tesla has been aware that the 4680 lines in Berlin will not take care of the initial production phases at the factory. Instead, it will rely on suppliers and its Kato Road 4680 lines in the United States to take care of the first months of production at Giga Berlin.
Tesla has reached a notable benchmark in its autonomous driving program after its Robotaxi fleet surpassed one million miles of unsupervised operation. The company made the announcement during its Cybercab event in Austin on September 3.
Tesla Vice President of AI Ashok Elluswamy told attendees he was happy to report the fleet had achieved one million miles of unsupervised Robotaxi operation as a testament to safety.
The new total marked a sharp increase from the 380,000 unsupervised miles Tesla disclosed during its second-quarter 2026 earnings update in late July.
In roughly six weeks, the company added about 620,000 miles. That acceleration followed Tesla’s decision to remove in-vehicle safety monitors from most of its operations outside the San Francisco Bay Area.

Tesla first launched Robotaxi service in Austin in June 2025 with safety drivers present. It later began fully unsupervised rides and expanded into Dallas, Houston, Miami, Orlando, and Tampa. The San Francisco Bay Area remains the exception, where a safety monitor still rides in the vehicle under California permitting rules.
The company has not released a city-by-city breakdown of the one million unsupervised miles.
The milestone arrived as Tesla began offering public Cybercab rides in Austin. The purpose-built vehicle has no steering wheel or pedals and is designed only for autonomous ride-hailing. Production versions joined the existing fleet of modified Tesla vehicles already operating in the service.
Tesla’s unsupervised mileage is growing at a double-digit weekly rate according to earlier company comments, yet its fleet size remains modest compared with established competitors. Waymo has accumulated more than 200 million fully autonomous rider-only miles. Tesla has described its own unsupervised operations as having recorded zero notable incidents in the period leading up to the July update.
The one-million-mile figure reflects Tesla’s shift from supervised testing to broader driverless service in multiple states. It also highlights the company’s strategy of using both existing Model Y vehicles and the new Cybercab to scale its network.

Whether the rapid recent growth continues will depend on further city expansions, regulatory approvals, and the performance of the purpose-built Cybercab in everyday paid rides. Tesla has not specified how many of the latest miles involved the new vehicle versus the rest of the fleet.
The announcement underscores Tesla’s progress toward a larger robotaxi network while illustrating the remaining gap in total autonomous experience relative to longer-operating rivals.
Tesla AI lead Ashok Elluswamy said this week that 24-hour Robotaxi service is close. Replying on X to a rider who wanted Cybercab trips all night, he wrote that the capability would arrive “next month or so” once “the next tech to merge on the v15 plan” is ready.
The comment landed on September 4, one day after Tesla opened public Cybercab rides in Austin. It is the clearest near-term timeline yet for overnight unsupervised operation. Tesla’s paid Robotaxi network currently runs from 6 a.m. to 10 p.m. seven days a week across Austin, Dallas, Houston, Miami, Orlando, and Tampa.
next month or so. the next tech to merge on the v15 plan will enable it.

That 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.
Elluswamy did not name the specific feature or say whether the change would apply first to purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list. The link to Full Self-Driving v15 is nevertheless significant.
Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.
By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states with what the company called an impeccable safety record and no notable incidents caused by the vehicles themselves. Tesla has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.
Overnight service would test that claim in lower-light conditions and would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.
Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale: Tesla has held back mass expansion until more of the v15 stack is merged, citing the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.
If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets.
That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.
It may also engage if we…

The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
