Tesla's V4 Superchargers are capable of speeds up to 600kW
@EstherKokkelman (Edited by Not a Tesla App)
Tesla has opened the first V4 Superchargers, which appear to have the potential to be twice as powerful as the model it replaces. The world is starting to learn more about this newest addition to Tesla's portfolio of DC fast-charging stations. Tesla started constructing its first fourth-generation Superchargers in the Netherlands earlier this month and officially opened them up to the public on March 15th.
Further details regarding the Supercharger V4's capabilities are now available courtesy of a recent peek at the new charging station by nearby Tesla owners. According to the charger's electric car specifications, it has a maximum power output of 600 kW and a maximum current of 615A at 1,000V.
This is the potential maximum for the new Supercharger V4, even if the highest-rated power is rarely maintained. The current restriction is at the level of the vehicle, as most, or potentially all Teslas today cannot manage to be charged at those levels.
This development might provide a glimpse into Tesla's upcoming electric vehicle ambitions. At Tesla's Semi delivery event, Tesla revealed that the Tesla Semi and Cybertruck would be the vehicles that would be able to take full advantage of Tesla's upcoming V4 Superchargers.
Longer Cables and Lights in V4 Superchargers
Although V4 Superchargers feature a simpler design, the TESLA lettering on the new Superchargers does light up to make the Superchargers easier to spot.
The cables at V4 Superchargers are also significantly longer than in previous generations. Tesla's previous Superchargers included fairly short cables that are about 6.5 feet (2m) long, but for V4 they've extended the length of the cables to almost 10 feet (3m) to make it easier to charge various types of vehicles.
During Investor Day, Tesla confirmed increasing manufacturing in preparation for a swift rollout. The new charger is projected to offer a higher charge rate than the Supercharger V3's existing 250 kW ceiling for existing vehicles. They will also likely have a solution for CCS charging compatibility for electric vehicles not made by Tesla, by having a built-in Magic Dock in the U.S.

Tesla has just opened up their Early Access Program, which we found out about just a few days ago - to FSD owners and subscribers in the United States. This new Early Access Program will offer regular owners the ability to get early FSD updates before they get widely released.
Early Access
Tesla has begun to slowly roll out a pop-up (and button) in the Tesla app, offering users the ability to enroll in the FSD (Supervised) Early Access Program in the United States. This update is rolling out slowly, so don’t be surprised if you don’t have it yet.
For now, this program appears to be limited to the United States. Users in Canada and Mexico, even those with existing Early Access, have not yet received an invite to the program.
Once you join the Early Access Program, at the very bottom of your app, where your VIN and software version normally appear, you’ll see a new “Early Access” link. Tapping this will show your status as a member of the Early Access program and also offers you the opportunity to leave the program if so desired.

How to Get In?
To be offered the program, you must own an AI4/Hardware 4 vehicle with FSD, either purchased or actively subscribed. Unfortunately, HW3 owners are not receiving this right now.
A pop-up will be displayed in your Tesla app once you get selected to join the program. If you dismiss the pop-up in a hurry, don’t worry. The ability to join Early Access stays as in the image below, and you can join the program at any time.
Ending your subscription while part of Early Access means your vehicle will be removed from the program.

Privacy
In exchange for receiving early builds of FSD, Tesla will increase the amount of data, video, and audio gathered from your vehicle, and the data will be VIN-associated, meaning less privacy and anonymity for users.
Any software updates or release notes you receive, both in-vehicle and in-app, will be watermarked with your vehicle's VIN. Tesla has been watermarking employee release notes since June of 2024 to reduce leaks, and this new Early Access program appears to follow a similar format, even though it is more widespread.

Cautions
Of course, earlier FSD builds are usually less stable and potentially less safe than wide release, so it’s important to remain more vigilant during FSD’s use. If anyone else uses the vehicle, make sure they’re also aware of the situation.
On the flip side, this is really exciting for many Tesla owners. Tesla’s Early Access program has normally been limited to employees and influencers, so it’s awesome to see regular owners getting an opportunity to get in on all the fun of testing out Tesla’s latest FSD functionality.
This new Early Access program could also mean that Tesla has a new level of confidence in future builds, where it’s now willing to make them available to more users. It could also have to do with Tesla’s FSD Unsupervised ambitions, where they may need more data than was already collected in order to successfully launch their Robotaxi this June.
Emissions Pooling is an incentive-based program supported by various governments—most notably the European Union—to help automakers meet strict carbon reduction goals under Corporate Average Fuel Economy (CAFE) standards.
CAFE standards mandate that automakers reduce the average CO₂ emissions across their fleet of newly manufactured vehicles. The EU’s 2025 targets are particularly aggressive, and manufacturers risk hefty fines if a sufficient portion of their new vehicles aren’t low- or zero-emission.
Emission Pool
Emissions pooling is a regulatory mechanism that allows automakers to combine their fleet CO₂ emissions to collectively meet environmental targets. Companies with low or zero emissions—like Tesla—can partner with higher-emitting automakers to help reduce their combined average and avoid costly fines.
In practice, this means pool members purchase emissions credits from Tesla, which uses its all-electric lineup to generate surplus credits. These credits help other manufacturers offset their emissions, while Tesla earns a tidy profit.
Tesla has long capitalized on this model, regularly selling emissions credits to strengthen its financials. Now, its European Union emissions pool is expanding again—with Honda and Suzuki joining existing members like Stellantis, Toyota, Ford, Mazda, and Subaru.
Green Bottom Line
Every automaker in Tesla’s emissions pool is effectively buying credits from a company with a 100% zero-emission fleet. In Q4 2024 alone, Tesla earned $692 million from regulatory and emissions credits, making up nearly 30% of its quarterly net income.
That’s a major chunk of profit driven by programs like emissions pooling—and with Honda now onboard, Tesla gains a significant new partner (and revenue stream) in the EU.
