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 taken home the “Overall Loyalty to Make” award from S&P Global Mobility for the fourth consecutive year, reinforcing Tesla owners’ willingness to come back. The 2025 awards are based on S&P Global Mobility’s analysis of 13.6 million new retail vehicle registrations in the U.S. from October 2024 through September 2025. The complete list of 2025 winners includes General Motors for Overall Loyalty to Manufacturer, Tesla for Overall Loyalty to Make, Chevrolet Equinox for Overall Loyalty to Model, Mini for Most Improved Make Loyalty, Subaru for Overall Loyalty to Dealer, and Tesla again for both Ethnic Market Loyalty to Make and Highest Conquest Percentage.
Tesla’s streak in this category started in 2022, and the brand has now won the Highest Conquest Percentage award for six straight years, meaning it keeps pulling buyers away from other brands at a rate no competitor has matched. Tesla’s retention among Asian households reached 63.6% and among Hispanic households 61.9%, rates that significantly outpace national averages for those groups. That breadth of appeal across demographics adds a layer of significance to a win that some might dismiss as routine.
The timing matters too. After several consecutive quarters of decline, Tesla’s share of U.S. EV sales jumped to 59% in Q4 2025. That rebound, arriving just as competitors were flooding the market with new models and incentives, suggests Tesla’s loyalty numbers are not simply the result of limited alternatives. Buyers are still choosing it when they have plenty of other options.
What keeps Tesla owners coming back has a lot to do with the and convenience of charging. The Supercharger network is the most straightforward example. With over 65,000 Superchargers globally, it remains the largest and most reliable fast-charging network in the world, and owners who have built their routines around it face a real practical cost when considering a switch. Competitors have made progress, but the consistency, speed, and availability of Tesla’s network is still the benchmark the rest of the industry is chasing. Then there is the software side. Tesla has built a model where the car you own today is functionally different from the car you bought two years ago, through over-the-air updates that add continuous game-changing improvements such as Full Self-Driving that has moved from a driver-assist feature to an increasingly capable autonomous system. For many Tesla owners, leaving the brand means starting over with a car that will not get meaningfully better over time, and that is a trade-off fewer and fewer are willing to make.
Tesla Robotaxi services in Austin have been operating since last Summer, but Tesla has admittedly been delayed in its expansion of the geofence, fleet size, and other details in a bid to prioritize safety as new technology rolls out.
But those barriers are being broken with new guardrails being removed from the program.
Tesla has achieved a significant advancement in its autonomous ride-hailing program. As of May 4, the Robotaxi fleet in Austin, Texas, has begun operating unsupervised during evening hours for the first time. This expansion moves beyond previous limitations that restricted unsupervised service to daylight hours, typically ending in mid-afternoon.

The change brings Austin in line with operations in Dallas and Houston. Those cities have supported evening unsupervised runs since their initial launches in April, and both recently received additions of new unsupervised vehicles to their fleets. This coordinated progress across Texas strengthens Tesla’s regional presence and provides a broader testing ground for the technology.
This milestone carries substantial weight in the development of autonomous vehicles. Extending operations into low-light conditions meaningfully expands the Robotaxi’s operational design domain (ODD)—the specific environments and scenarios in which the system is approved to operate safely without human intervention.
Nighttime driving presents unique technical demands: diminished visibility, headlight glare from oncoming traffic, reduced contrast for identifying pedestrians and lane markings, and greater variability in camera sensor exposure.
Tesla’s pure vision approach, powered by neural networks trained on vast real-world datasets rather than lidar or pre-mapped routes, must handle these variables reliably. Demonstrating consistent unsupervised performance after sunset validates the robustness of the end-to-end AI stack and its ability to generalize across diverse lighting conditions.
Beyond technical validation, the expansion holds important operational and economic implications. Evening hours often coincide with peak urban demand for rides, including commutes, dining, and entertainment outings.
Enabling service during these periods increases daily vehicle utilization, allowing each Robotaxi to generate more revenue while gathering additional high-value training data. Higher utilization accelerates the virtuous cycle of data collection, model improvement, and further ODD growth.
Looking ahead, this step paves the way for more ambitious rollouts. Success in low-light environments positions Tesla to pursue near-24-hour operations, potentially integrating highways and expanding into varied weather patterns. Regulators worldwide frequently demand evidence of safe performance across day-night cycles before granting wider approvals.
Proven capability in Texas could expedite deployments in planned cities such as Phoenix, Miami, Orlando, Tampa, and Las Vegas during the first half of 2026.

Moreover, scaling evening service supports Tesla’s long-term vision of a high-efficiency robotaxi network. Greater fleet productivity lowers the cost per mile, making autonomous mobility more accessible and competitive against traditional ride-hailing.
As the company iterates on software updates informed by nighttime data, reliability is expected to compound rapidly, unlocking denser urban coverage and longer-distance trips.
In summary, the introduction of an unsupervised evening Robotaxi service in Austin represents more than an incremental schedule adjustment. It signals a critical maturation of the underlying technology and sets the foundation for broader geographic and temporal expansion.
With Texas operations gaining momentum, Tesla is steadily advancing toward transforming urban transportation at scale.

Tesla Cybercab just rolled through Miami inside a glass box
Tesla paraded a Cybercab in a glass display at Miami’s F1 Grand Prix event this week.
Tesla set up an “Autonomy Pop-Up” at Lummus Park in Miami Beach from April 29 through May 3, 2026, embedded within the official F1 Miami Grand Prix Fan Fest. The centerpiece was a Cybertruck towing the Cybercab inside a glass display case marked “Future is Autonomous,” rolling through the beachfront crowd.
Miami is on Tesla’s confirmed list of cities for robotaxi expansion in the first half of 2026, making the promotion a strategic promotion that lays groundwork in a target market.
This was not Tesla’s first time using Miami as a showcase city. In December 2025, Tesla hosted “The Future of Autonomy Visualized” at its Miami Design District showroom, coinciding with Art Basel Miami Beach. That event featured the Cybercab prototype and Optimus robots interacting with attendees. The F1 pop-up this week marks Tesla’s return to Miami and follows a pattern Tesla has been running since early 2026. Just two weeks before Miami, Tesla stationed Optimus at the Tesla Boston Boylston Street showroom on April 19 and 20, directly on the final stretch of the Boston Marathon, letting tens of thousands of runners and spectators meet the robot for free, generating massive earned media at zero advertising cost.

Tesla has confirmed plans to expand its robotaxi service to seven cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas, building on the unsupervised service already running in Austin. Musk has said he expects robotaxis to cover between a quarter and half of the United States by end of year. On the production side, Musk told shareholders that the Cybercab manufacturing process could eventually produce up to 5 million vehicles per year, targeting a cycle time of one unit every ten seconds. Scaling robotaxis to 10 million operational units over the next ten years is a key condition of his compensation package, alongside selling 20 million passenger vehicles.
As for the Cybercab’s price, Musk has said buyers will be able to purchase one for under $30,000, with an average operating cost around $0.20 per mile. Whether those numbers hold through full production remains to be seen.
