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.

Tesla has partnered with XPEL, one of the leading manufacturers of automotive tints, for an OEM-approved window tint. Previously, Tesla did not approve window tints on its vehicles and had even denied warranty claims for window issues if the windows were tinted.
Over the past year, Tesla Service has stopped denying warranty claims for cracked windows caused by excessive motor force, factory misalignments, or other minor issues — even when window tints are applied.
XPEL / Tesla Partnership
With this partnership, Tesla owners can find window tints directly through the Tesla app, just like they’d find any other Tesla accessory. The difference is that the purchase is completed on XPEL’s website instead of through the Tesla app.
Tesla is essentially promoting the service and presumably making it an approved product. However, the Tesla owner also benefits from having a better warranty instead of just going through XPEL directly.
XPEL offers two official tints for all Tesla vehicles, including the Cybertruck - its Prime XR+ and Prime XR lines. The best part is that XPEL and Tesla’s combined warranty covers the cost of reinstallation if the glass is damaged under Tesla’s vehicle warranty, which means you won’t have to pay anything additional to get your tint replaced.
You can check out the official specifications of the two tint options below.

Vehicle tints, like the ones XPEL offers, have numerous advantages. They reduce cabin heat, block UV rays, minimize glare from external light sources, and increase privacy.
The order is placed through XPEL’s website, and then you will be referred to your local installer. They will conduct the installation, and then you’re set and ready to go - no payment is needed from the installer. The process takes between 1-2 business days, including time for the tint to fully set on the glass. This reduces the chance of the window tint peeling prematurely from your frameless window, which automatically lowers and raises when you open and close the door.
For now, this service is only available in the United States, and you can get referred to an XPEL official installer through the button on XPEL’s Partner website here. You can select the shade/tint percentage of your window film on the installation date.
Of note, windshield tinting is not available through the partnership program, but XPEL advises that your local installer can provide you with an additional quote on the day of installation.
It’s that exciting time again when a major Tesla software update is on the verge of being released. Tesla update 2025.20 is now being tested on employee vehicles, but since Tesla is very strict about sharing updates early, it’s anyone’s guess as to what’s in it.
This update is now reaching employee vehicles, which means it will still be a few weeks before it reaches customers. However, there’s plenty to be excited about. Given the trail of breadcrumbs found in Tesla’s code recently and from recent announcements of upcoming features, there are plenty of hints about what could be in it.
Let’s break it down and see what may be included in Tesla update 2025.20.
Grok
The existing voice command system gets the job done for basic controls, but it’s far from an intelligent, conversational assistant that many have come to expect from their cell phones or other smart devices. The integration of Grok is expected to change that.
Not only is Grok expected to bring a much more reliable system that’s able to parse commands from conversational phrases, but it’ll also drastically expand what the vehicle is capable of understanding and responding to through its voice system.
If you haven’t used Grok, you have several articles on what you can expect. It’ll be a drastic improvement that will reshape the way many of us drive. That may sound like we’re blowing the feature out of proportion, but if you spend a lot of time by yourself in your vehicle, this could have a huge impact on your commute.
Grok could be used as a conversational assistant, a sort of virtual friend who knows a whole lot just about any topic. Sure, you’ll be able to ask it for the weather or stock quotes or when Tesla is holding its next event, but the real power of it is just to be able to carry on conversations about a specific topic.
So here’s what we can expect. A virtual assistant who can execute vehicle commands like opening the glove box, which will be a direct replacement for the voice command system. You’ll also be able to ask general knowledge questions and carry on a conversation about any topic.
The responses won’t be limited to text like they are in the voice command system. Grok will have its voice, just like it does in the Grok app, so you’ll be able to hear your responses, letting you stay focused on the road. However, there likely won’t be a way for Grok to respond with anything except text or voice, for example, it likely won’t be able to display a photo.
Since Grok is replacing the vehicle’s command system and it’s mostly a backend change, we expect it to be available on older vehicles as well, such as those with Intel MCUs.
Grok is close to being released, so if it isn’t included in update 2025.20, it’s expected to be soon afterward, as Grok code has already been found in the previous Tesla update. The code discovered includes UI elements and a personality button like the Grok app.
New Vehicle Keys
With the Robotaxi Network launching as soon as June 12th in Austin and Elon confirming the project is well ahead of schedule, we’re anticipating Tesla will unveil the Robotaxi half of the Tesla app and the in-car interface sometime soon. While we don’t expect to see the in-car interface for both the front and rear screens for vehicles just yet, we could start seeing some other aspects, such as new virtual keys.
Two new keys were found: “Rider Keys,” which allow other drivers to access your vehicle when it is in “Fleet Mode,” and a new type of key called “Pre-delivery.” These keys will presumably let you unlock a vehicle but have limited capabilities. They could allow you to open and inspect your new vehicle, but not start it.
This could remove another human component when picking up your new Tesla.
Trailer Visualizations
Trailer visualizations could be added soon following confirmation from Wes Morril, Cybertruck’s Lead Engineer. Trailers are typically depicted as an additional vehicle or a truck. While the vehicle can accurately detect the trailer, the visualization leaves something to be desired.
Tesla already renders a series of objects in the visualizations, but trailers, along with trains and gates are some of the most requested additions.
Wes Morril also mentioned that Tesla may start rendering Cybertrucks in the visualization. It’s not clear whether he meant that Tesla was updating the truck's 3D model to be a Cybertruck, or if Tesla would display a special Cybertruck model specifically when the vehicle detects a Cybertruck.
While the Cybertruck has a polarizing design, this could be a fun addition. Years ago, Musk commented that Tesla would eventually render other Tesla vehicles as themselves in the visualization, even in their same real-life color, but it seems that Tesla dropped that idea and decided to keep the visualizations simpler.
The feature allows users to create their own custom wrap designs using a Tesla-provided template. It also allows them to create a custom license plate that is displayed in the visualization, letting you create a fun vanity plate or display your actual license plate.
Child Left Behind Detection
Tesla recently launched Child Left Behind support in Europe on the new Model 3. This feature uses the cabin radar to detect if a child has been left behind in a vehicle, and then takes some critical emergency steps. If an unattended child is detected, the vehicle will flash its exterior indicator lights, play an alert tone, and send a notification to your Tesla App. This repeats at regular intervals until you return.
We’re also expecting Tesla to improve this feature by automatically enabling the climate system in the vehicle when it detects a child left alone in the vehicle. In a critical scenario, Tesla previously stated that it would also automatically call emergency services if the driver doesn’t respond to prompts to return to the vehicle.
Since this feature was just added to a single model in select countries in update 2025.14.12, it appears that Tesla wants to collect data before expanding it further to reduce false positives. Since the feature was just rolled out to the public a few days ago, it may be too soon to expand it to other vehicles in update 2025.20, but it’s possible we may see it included in a few more regions or see another model supported.
Smart Child Seats
Rendering of what Tesla's integration could look like
@dkrasniy
Back in 2024, we found some code and preview images for Smart Child Seats, which would let the vehicle communicate with smart child seats that are already available. The seats could communicate with the vehicle about being properly installed and confirming the child is buckled.
They could also provide warnings if the child has been left in the seat too long or if the car seat belt has been unbuckled.Quality of Life Improvements
Emergency Vehicle Alert
Tesla has recently started processing audio data, enabling it to not only detect emergency vehicles through its cameras but also through audio. This capability could allow the vehicle to detect an emergency vehicle much sooner.
Supercharger Dynamic Pricing Support
Not a Tesla App
Tesla recently announced that some Superchargers are transitioning to a new dynamic pricing model, which sets the price based on the number of vehicles charging rather than the time of day.
This new pricing model would adjust the price of these Superchargers based on their actual real-time usage when you begin Supercharging. Your price is locked in when you begin Supercharging and won’t change halfway through, so you know exactly how much you’ll be paying.
This change means that a Supercharger could now potentially be cheapest during the day if few vehicles are using it. However, it could also be more expensive at night if it’s under high usage.
These changes make the charging price a little more fair and should help Supercharger congestion, incentivizing drivers to spread out to other nearby Superchargers that may have lower usage and, therefore, lower costs.
Tesla already showed off what the new interface will look like in the vehicle, so we expect that to be implemented in this upcoming 2025.20 update. The updated Supercharger UI will display an arrow next to the Supercharger price, indicating whether the price is higher or lower than anticipated based on historical usage. It’ll also include a “Low Price” or “High Price” label to help consumers decide.
There will also be a new “Find Lower Price Charging” button that will display nearby Superchargers that have lower prices and are less congested.
The Tesla app recently added support for this new charging model in app update 4.44.5.
Quality of Live Improvements
We could also see some other smaller, quality-of-life improvements from Tesla. First up are some improvements to Car Wash Mode, which will provide an alert for anyone who inadvertently lowers their window during a car wash.
We’re also hoping to see Tire Fill Assist, which will likely check the Bluetooth TPMS while you’re filling your tires. It could also give you audible feedback through the vehicle’s internal speakers or outside speaker (PWS) when the tire is approaching the set limit.
Last, but not least, we’re continuing to hold onto the hope that Tesla adds Steam Support to its entire lineup of vehicles. Ever since removing the additional RAM from the Model S and Model X, Tesla has quietly killed Steam Support - but oddly enough, it has still provided updates for it. We’d love to see SteamOS make an appearance on Tesla vehicles - what’s more futuristic than having your vehicle running Unsupervised FSD while you take a break and do some gaming?
When Is It Coming?
This update just started rolling out to employees, so it usually takes two to three weeks before it starts rolling out to the first public vehicles. Expect this update to start rolling out sometime in June, which just so happens to coincide with Tesla’s Robotaxi rollout.
