Tesla has now enabled 325kW charging at its V4 Superchargers. Right now, this is exclusive to the Cybertruck, which is the first vehicle to charge above 250kW at Tesla’s Superchargers. This new charging speed was initially being tested by Tesla in early December 2024 at select Supercharger sites in the United States, but this speed upgrade is now rolling out across North America.
V4 Superchargers
The new 325kW peak charging speed has been enabled at V4 Supercharger posts across North America - in both Canada and the United States. V4 Supercharger posts also bring longer cables - a great boon for the Cybertruck in particular, which can sometimes be hampered by the short V2 cables.
While V3 posts are still the most common, Tesla’s Supercharging team is working on upgrading older sites with V4 hardware, including pull-through tow-friendly Supercharging stalls. Tesla’s V4 stalls currently make up approximately 14% of the Supercharger network today - which is a massive improvement since Q4 2023, where they made up just 2%.
Faster Charging
The new 325kW peak speed will bring about a 5-minute improvement in charge times, as per some initial testing by Cybertruck owners. That brings the current 0-80% charge speed from 40 minutes down to just 35 minutes. This is mostly due to the vehicle not being able to sustain the higher charge speeds for a significant length of time.
And the best part? This new feature was enabled with an OTA update to the Superchargers. Max de Zegher, Tesla’s Director of Charging, pointed out that this overnight change was delivered quickly, efficiently, and quietly - all without on-site visits.
Being able to push software updates to Superchargers, without requiring on-site visits, is incredibly efficient & powerful. https://t.co/SXaeKfhKes
Your Cybertruck’s touchscreen will display the location of 325kW chargers and automatically prefer navigating to these faster chargers, depending on stall availability. This is similar to how enabling Tow Mode will make your vehicle prioritize Supercharger sites with tow-friendly stalls.
Faster Charging Coming
Tesla also confirmed that it is working on its V4 cabinets, which will further upgrade the peak charging speed of the Cybertruck to a staggering 500kW. That’ll be double what other Teslas can do today - due to the massive improvements brought forward by the new 800V architecture.
We expect the arrival of the new V4 cabinets and their 500kW charge speeds to even further boost just how fast Cybertruck can charge. We expect that 35-minute charge time to drop to 30 minutes or less, depending on the Cybertruck’s updated charge curve.
Other Vehicles Next?
Currently, the Cybertruck is unique with its 800V high voltage and 48V low voltage architectures. While we expected Tesla to bring these two big changes to their first mass-market refresh - the Refreshed Model Y Juniper, that didn’t come true. As such, we don’t expect the new 325kW speed to open up to older vehicles - at least - not yet.
However, there is still room for Tesla to continue improving vehicle charge speeds, features, and curves. They recently enabled a new battery-heating feature for RWD Standard Range vehicles with LFP battery packs, allowing them to Supercharge even faster in cold environments.
Competition is Speedy
Some competitors have exceeded Tesla’s Supercharger speeds - and not just speeds - but overall charge curves. This is especially true with some Chinese competitors - who are pushing LFP battery packs to charge at a stable 150kW across the entire 30-80% range.
Tesla vehicles currently struggle to maintain the charge rate over a longer period of time, which means that while they start fast, they peter out more quickly than other vehicles. The time difference between faster-charging vehicles like the Porche Taycan and the Model 3 was about 60 minutes across an 800-mile distance.
That’s not a huge difference in time overall, especially considering the difference in price points between a Taycan ($101,000 USD - starting) versus a Model 3 ($47,490 USD - LR AWD). It sounds like Tesla is looking for good charging speeds while maintaining battery health and keeping prices low.
While charge speeds may not be the best in the industry, the number of locations and reliability of Superchargers currently more than makeup for it.

According to a new report from Business Insider, Tesla is planning a week-long production pause for the Cybertruck and Model Y lines at Giga Texas. On the surface, the reason seems pretty straightforward: maintenance and line upgrades.
But Tesla has been infamous for never shutting down lines unless it's an absolute production necessity. Given that this is the third production pause in the last 12 months, this suggests that Tesla is planning something other than routine maintenance.
Official Story
The facts, as reported by BI, are fairly straightforward. Tesla will be shutting down the Model Y and Cybertruck lines from June 30th to July 4th. In a staff meeting at Giga Texas, Tesla stated that the pause would enable maintenance and upgrades to help ramp up production.
While this could seem odd for the recently updated Model Y and Cybertruck lines, it also makes sense as Tesla continuously makes production improvements, rather than waiting for model year updates.
There definitely feels like there’s more to this story than a simple pause, but the timing and context suggest this pause is far more significant.
The Affordable Model
The key to this shutdown is Tesla’s strategy for its more affordable model. Tesla has pivoted away from building Giga Mexico, and is instead planning to build both the Cybercab with its unboxed assembly process, as well as the next-gen affordable vehicle at Giga Texas.
For now, Tesla plans to build the affordable model based on existing production lines within Giga Texas, rather than build a standalone line. This is mostly because Tesla intends for the affordable model to have a high part familiarity with the Model 3 and Model Y.
The Model Y line, in particular, is the prime candidate for this retooling. It is Tesla's most refined high-volume production line, and the tooling and equipment on the line are perfectly suited to enable Tesla’s quick transition to producing the new model.
A week-long shutdown is not enough time for a complete overhaul, but it is the perfect window to begin preparatory work. This could include installing new mounting points for future robotics, rerouting utilities, or even running initial trials for new assembly processes in a portion of the line.
Timing is Everything
This theory makes even more sense in the context of recent events. The cheaper model was initially planned for the first half of 2025, but following reported delays, the timing seems right for Tesla to start incorporating changes to support the new vehicle. While Tesla initially planned for a cheaper model to be based on the Cybercab with its unboxed assembly, they decided to produce one based on the current assembly line to get to market sooner. This isn’t the cheaper, “$25k” vehicle we were all hoping for, but instead a more affordable version of the Model 3 or Model Y.
While the Cybertruck line is likely undergoing standard ramp-up tweaks, the shutdown of the Model Y line likely presents something more. While it could also include maintenance and incorporate updated tools, it may include changes required for the newer model.
More Than Maintenance
While the official reason reported by Business Insider seems fairly plausible, there’s always more under the surface when it comes to major decisions like this with Tesla. Using the planned maintenance window to quietly begin the process of retooling is the kind of move we expect from Tesla.
Just days before Tesla’s planned launch of the Robotaxi network in Austin, a group of local lawmakers has sent a letter to Tesla, urging them to delay the launch. Citing a new state law set to take effect on September 1st, the letter asks Tesla to pause its launch until it can formally comply with the new framework.
On the surface, this could sound like a significant roadblock. However, upon closer examination of the lawmaker’s concerns, the requirements of the new law, and the upcoming unified federal autonomy regulations, the request may be more political theater than a genuine obstacle.
In fact, Tesla’s Robotaxi service appears to already meet the spirit—and likely the letter—of the upcoming regulatory framework.
The Letter and the Law
The letter, penned by State Senator Sarah Eckhardt, formally requests that Tesla postpone its planned Robotaxi launch this month until the new and more comprehensive autonomous vehicle law is in effect on September 1st. It's important to note that this isn’t a legal injunction; it doesn’t have any power, and Tesla is under no obligation to comply or even reply. The letter is a formal request, a piece of political pressure intended to encourage proactive compliance.
So, what does this new law demand? It has five key requirements for autonomous vehicle operation in Texas.
Barely A Speed Bump
A detailed look reveals that Tesla's existing technology and practices likely already meet every single requirement of the upcoming regulations, so let’s dive in.
1) Capable of operating in compliance with state traffic laws.
This is the fundamental purpose of FSD - complying with traffic laws to get a passenger from Point A to Point B. The system is designed to adhere to traffic laws, and in fact, sometimes sticks to them too closely (like the NHTSA stop).
2) Equipped with a recording device.
This is probably the easiest requirement when you look at a Tesla. Every vehicle is a rolling 360-degree security suite, equipped with multiple cameras and internal sensors that document every action taken by the vehicle.
3) Compliant with federal law, including federal motor vehicle safety standards.
Tesla is currently deploying Model Ys for its Robotaxi network pilot, which means that they are fully compliant with FMVSS standards. This will likely change once Cybercab begins to deploy, but the NHTSA is working on accelerating federal regulation for vehicles without driver controls in the near future.
4) Capable of achieving a “minimal risk condition” if the automated system is rendered inoperable.
When the system detects a critical fault or issue it cannot handle, it must slow down, activate hazard lights, and pull over to a safe location at the side of the road. That is very doable, and likely within Tesla’s calculations for how they will handle system aborts and other incidents. In fact, the Model Y robotaxis with a safety driver in the passenger seat have been spotted with buttons on the screen that say “Emergency Stop” and “Pullover.”
5) Registered, Titled, and Insured under Texas law.
This is a bog-standard requirement. Every vehicle operator must meet those three requirements, and as Tesla’s Model Ys currently driving the roads in Austin are sporting manufacturer plates, this is likely already done.
While these Texas lawmakers are asking for a pause, the NHTSA is actively working to make it easier for companies like Tesla to deploy autonomous vehicles. This state-level scrutiny, while perhaps well-intentioned, is a clear example of the challenge of deploying a national network under fragmented regulations.
Ultimately, this letter is unlikely to be anything more than a political statement. It will be logged and acknowledged, but it presents no new technical or legal hurdles for Tesla to clear before its planned launch. For an autonomous future, this isn't even a bump in the road.
