Tesla’s V4 Supercharger appeared in new project plans for a site in Danvers, Massachusetts, with a design that is strikingly similar to the company’s 72 kW Urban Supercharger. However, project details outlined in blueprints for the Danvers Supercharger seem to indicate this is Tesla’s next big development in its next-gen charging posts, but some questions still remain.
Tesla’s V4 Supercharger
Tesla’s V4 Supercharger will, of course, succeed the 250 kW-capable V3 Superchargers that were released in 2019. The V3 Supercharger was an outrageous update and a huge development to the expedited process of charging Tesla’s EVs. Rates of up to 1,000 miles of range added per hour are capable with the V3 Superchargers, but they are also only available to Tesla vehicles, which is where the V4 may be coming into play.
Along with the rumored CSS support that the V4 Supercharger will pack, Tesla seems to be revising a recently-released 72 kW Urban Supercharger design for the new stalls. In the project outline for the Danvers, Massachusetts Supercharger, the design for the “Alternative Supercharger Post” is strikingly similar, but there are a few details that lead us to believe this is what Tesla is planning to utilize for the new design.
Tesla’s Urban Supercharger can be wall-mounted and installed virtually anywhere
Initially, the Alternative design in the blueprints is massive: 6′ 4.5″, weighing 200 pounds. That’s significantly larger than the Urban Supercharger, which is compact and perhaps only four feet or less in height. It towers over the V3 Supercharger design, which is also present in the blueprints and seems to be the project’s more-likely outfitting when it is complete (courtesy of @JH_Beford on Twitter).

We recently reported on some rumors surrounding the V4 Supercharger design, and it does appear to be somewhat similar from a very elementary perspective to what descriptions of the new shell would be. However, there are some things that still remain in question as the V4 Supercharger design has not yet been made public by Tesla.
CCS Support
The project design lacks any mention of potential CCS Support on the V4 Supercharger, which is what most people would expect moving forward from Tesla. The automaker has been utilizing a Pilot Program in Europe that allows other EV brands to utilize Supercharger stalls. This project is available in sixteen countries in Europe, and Tesla has made it clear that, eventually, the capability will be available in the United States. For now, it is too much of an advantage as Tesla continues to grow, and the company keeps it exclusive to Tesla vehicles in the U.S.
However, as we are already a month into the second half of 2022, it gives Tesla less time to roll out the “new Supercharger equipment that will enable non-Tesla EV drivers in North America to use Tesla Superchargers.” These quoted words come courtesy of the White House.
CCS Support may not be on these designs for several reasons, and it could be that Tesla simply hasn’t finalized a design for that Supercharger. Additionally, this could be an entirely different design altogether, and while it could be the V4 Supercharger, Tesla may not have plans to put CCS Support on the V4. That could perhaps be saved for another design.
900v Architecture
Tesla’s V4 Supercharger will also likely support ultra-fast charging architectures like a rumored 900V setup for the Cybertruck. These higher-voltage architectures enable ultra-fast charging and can supply high-performance or high-workload vehicles with range in short amounts of time.
Tesla is also likely to head toward a 350 kW charging rate, which is present in Electrify America chargers. These chargers are perfect for high-voltage vehicles as they can charge vehicles faster, and most importantly, the vehicles can support them. Their higher voltage architecture can stabilize the charging process for these higher-powered chargers. The Porsche Taycan has an 800v architecture, which enables faster charging, less weight, and high performance, all at lower temperatures.

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.
