Elon Musk shares details on Tesla Model Y redesign, battery cell production in Giga Berlin
One of the most notable moments in Tesla CEO Elon Musk’s visit to the Gigafactory Berlin complex was an impromptu interview with several members of the media. Musk discussed numerous topics in his 9-minute interview, from the quick buildout of Giga Berlin, the upcoming facility’s next-generation paint shop, and why it is pertinent for the German electric vehicle factory to be constructed as soon as possible. But beyond this, Musk also shared details about a couple of pertinent initiatives that will be rolled out in Gigafactory Berlin: the Model Y redesign and local battery cell production.
Based on Musk’s comments, it appears that Giga Berlin is poised to be Tesla’s most advanced factory yet. After candidly admitting that the vehicles from the German plant will likely have better paint than those produced in the United States, Musk noted that the Made-in-Germany Model Y will also be undergoing a radical redesign. Musk stated that some of these updates to the Model Y will be discussed during Battery Day. Following is Musk’s statement as transcribed by Tesla bull and enthusiast James Stephenson.
“Like I was saying, you know, we build the factory and then also there’s a bunch of innovative stuff that we will be doing here that we will tell you about in the future… It’s not just a copy of the Model Y. It’s actually a radical redesign of the core technology of building a car. And some of this, when I do Battery Day in September, I’ll be talking about what we are going to be doing here in Berlin. But it will be the first time there’s going to be a transformation in the core structural design of the vehicle. It’s quite, quite a big thing,” Musk remarked.
Apart from providing new details about the Model Y redesign, Musk also confirmed that Tesla is looking to produce battery cells in the Gigafactory Berlin complex. The Tesla CEO shared this detail while explaining why there is such a rush to get Giga Berlin online as soon as possible. According to Musk, it is pertinent to move fast because of Tesla’s mission, which is to accelerate the advent of sustainable energy. Ultimately, Musk noted that for the sake of the climate, companies like Tesla must move as fast as they can.
“I believe in speed. And I think also, well, to be serious for a second, I think it’s very important for our climate that we move quickly. It matters. I think it’s very important that we accelerate the transition to sustainable energy and that we move as quickly as possible. So this is the reason for the sense of urgency… And I’ve been saying this for a long time. It’s good to see some companies like VW taking this seriously now, but still only a very small percentage of cars that are made are electric.
“And then I think we will probably do more than cars here. I think we will provably be building some battery cells here. I think that’ll be good for stationary storage of wind and solar. Essentially, the three elements that are necessary for a sustainable energy future are energy generation, energy storage, and electric transportation — electric cars, and eventually, electric aircraft. Ironically, everything will go electric except rockets,” Musk said.
Interestingly enough, initial plans for Gigafactory Berlin actually had large areas of the site allotted for a battery cell facility. With this in mind, it appears that Tesla has been pondering local battery cell production for Giga Berlin for some time now. Perhaps the bigger question now is if the company will be utilizing a partner for the Berlin site, similar to its strategy with Panasonic in Gigafactory Nevada, or if Tesla will operate its own custom battery cell lines, similar to the “Roadrunner” project in Fremont.

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.
