Tesla shares Supercharger V3 details, critiques Porsche’s 350 kW chargers
Tesla CEO Elon Musk and CTO JB Straubel revealed the first details of the company’s upcoming Supercharger V3 network during the company’s recently conducted first-quarter earnings call. The discussion about the next-generation charging stations came as a response to a question addressing Porsche’s 350 kW IONITY network, which is set to outgun Tesla’s 120 kW Superchargers when it gets fully rolled out.
According to Musk, Tesla will introduce an improved version of its Superchargers, though they would not be along the same specs as Porsche’s 350 kW stations.
“We’re definitely going to be improving our Supercharger’s technology. The thing about a 350 kW charger is that it doesn’t actually make a ton of sense, unless you got a monster battery pack or have like a crazy high C rating… We think 350 kW for a single car; you’re gonna frag the battery pack if you do that. You cannot charge a high-energy battery pack at that rate, unless it’s a very high kW battery pack. So, (for us), something along the couple of hundred, 200-250 kW, maybe.”
Musk’s statements were backed up with an explanation from Tesla CTO JB Straubel, who noted that the levels of power for Supercharger V3 involve a considerable amount of balancing. Straubel further stated that Tesla could make a 300-400 kW Supercharger, but such a system would not be a useful tradeoff for the company’s consumer base.
“That’s definitely sort of the power level that we’ve discussed and explored. Some of it also comes down to an optimization around utility versus cost, and tradeoffs in the car itself. There is a tradeoff, fundamentally, between charge speed and essentially range, and cost of the battery. We look at that pretty carefully. We understand the tradeoff. We could design cells and a pack that could charge at, you know, faster than 300-400 kW, but it’s not a very useful tradeoff to the customer.”
Elon Musk also provided a real-world explanation that differentiates Tesla’s Supercharger V3 to Porsche’s 350 kW IONITY network.
“Energy is range, and power is your peak acceleration, the rate in which you consume energy. It’s more important to have long range than it is to have a super fast charge time. You can sort of think about this in the devices that you use. Would you rather have a cellphone that charges in 5 minutes or 10 minutes, but only lasted 2 hours. Or, if you’d like a cellphone that can last two days, and maybe takes an hour to charge?”
Musk also discussed the idea of opening the Supercharger network to other electric car makers. According to the CEO, the Superchargers are not a “walled garden,” and that Tesla would be happy to partner with other players in the EV industry. So far, however, Musk noted that no automaker had approached Tesla about a possible Supercharger partnership.
“We’ve always said that this is not intended to be a walled garden, and we’re happy to support other automakers and let them use our Supercharger stations. They would just need to pay, you know, share the costs proportionate to their vehicle usage, and they would need to be able to accept our charge rate or at least our connector, at least have an adapter to our connector. This is something that we are very open to, but so far, none of the other car makers have wanted to do this. It’s not because of opposition from us. This is not a walled garden.”
As we noted in a previous report, a key difference between Tesla’s Supercharger and Porsche’s IONITY network lies in the rates the companies demand for each service. Tesla has maintained that the Superchargers are not being built for profit, while Porsche deputy chairman of the executive board Lutz Meschke noted that using the IONITY network would roughly cost the same as filling up an ICE vehicle with gasoline.
Tesla is lowering the monthly price of its Cybertruck Windshield Protection Plan from $35 to $25. The new rate will apply to the first payment on or after October 1, 2026. Tesla has told subscribers that all other benefits stay the same.
The plan covers unlimited repairs for chips and minor cracks on the front windshield. It also includes one full replacement every 12 months at no extra charge. Additional replacements in the same year carry a $100 deductible. Service is performed with Tesla glass and camera calibration, which matters because Autopilot and Full Self-Driving rely on those lenses behind the windshield.

There is no long-term contract. Coverage applies only to the front glass and does not include collision, vandalism, or weather damage.
The Cybertruck’s large, complex windshield has been more expensive to replace than glass on Tesla’s cars, which is why the pickup started at a higher subscription price. The $10 monthly cut reduces the annual cost from $420 to $300. Tesla has not publicly explained the change. The timing coincides with a year of claims data after the plan was extended to the Cybertruck.
Tesla sells several related protection products as monthly subscriptions through the Tesla app. The Windshield Protection Plan is also offered on other models. Model 3 and Model Y currently cost $16 a month. Those passenger-car rates are unchanged in the latest Cybertruck notice.
The Wheel and Tire Protection Plan covers road-hazard damage such as potholes, nails, and debris. Repairs are unlimited. Each wheel or tire replacement appointment has a $25 deductible. Pricing varies by model and whether the vehicle is a Performance version. Tesla is raising some of those rates on the same October 1 date.
Reported examples include Model 3 Performance moving from $16 to $24 and Model Y Performance from $20 to $24. Cybertruck wheel-and-tire coverage has been listed at $20 a month for the standard configuration.
A separate Luxe Package bundles four years of windshield coverage, wheel-and-tire coverage, and recommended maintenance on certain new Model S, Model X, and Cyberbeast orders, although the Model S and X are now defunct.
Tesla also offers an Extended Service Agreement after the basic vehicle warranty ends. That product covers many Tesla-manufactured parts rather than glass or tires. Together, the plans give owners a menu of targeted, cancel-anytime coverage instead of relying only on auto insurance.
UPDATE: The number has now been updated to 45 units, up from 7!
Here we go! Tesla has just added another 38 Cybercabs to its Robotaxi fleet, bringing the total up to 45, according to the Texas DMV.

Tesla is bolstering its Cybercab fleet with the State of Texas’s regulatory bodies ahead of the planned launch of the all-electric ride-hailing vehicle this Thursday.
Seven purpose-built Tesla Cybercabs have been added to Texas’s official automated vehicle registry, appearing in the Texas Motor Carrier Credentialing System (TxMCCS) public lookup just three days before Tesla’s invite-only Cybercab launch event in Austin on September 3.
The records, visible through TxDMV’s Motor Carrier and Automated Motor Vehicle Operator Lookup, list seven 2026 Tesla Cybercabs under Tesla Robotaxi, LLC. Their VINs begin with the 5YJA prefix, distinct from the 7SAYG Model Y robotaxis that already dominate Tesla’s Texas fleet.
Community trackers that scrape the same public database recorded the new entries on August 31, bringing Tesla’s authorized Texas robotaxi total to 276 vehicles: 269 Model Ys and the seven Cybercabs:

Texas Senate Bill 2807, which took effect in late May 2026, created a self-certification framework for commercial Level 4 operations. Operators file through TxMCCS, attest to SAE Level 4 capability, maintain insurance, and keep an active vehicle list.
Tesla completed that process months earlier for its existing Model Y Robotaxi service, which has carried paying passengers in Austin, Dallas, Houston and other markets. Adding the Cybercabs to the same authorization means the new two-seat, steering-wheel-free vehicles are now legally recognized for commercial use on Texas roads.
The timing is deliberate as Tesla scheduled the September 3 event at its Austin campus after sending invitations to selected Robotaxi riders and other guests. The company has described the evening as a chance to “experience the future of full autonomy” and plans to livestream it.
Production Cybercabs, which lack pedals and a steering wheel, have been rolling off the Giga Texas line for months; some earlier examples still carried temporary driver controls for data collection. Registering a small fleet of the finished design immediately before the public event signals that Tesla intends to move the purpose-built vehicle from factory and test tracks into the same Robotaxi app already used by Model Y passengers.
The seven units remain a tiny fraction of Tesla’s overall Texas authorization and far smaller than competing fleets. Registration does not automatically equal unsupervised public rides; it is the legal prerequisite.
Still, the sudden appearance of Cybercab VINs in the state’s lookup system, after a year of Model Y-only listings, is the clearest official confirmation yet that Tesla’s dedicated robotaxi hardware is entering the regulatory pipeline at the same moment the company is preparing to show it to invited guests and a global livestream audience.
Whether those seven vehicles appear at the September 3 event or begin carrying passengers shortly afterward, their presence in TxMCCS marks a concrete regulatory step that has been anticipated since the Cybercab concept was first revealed.
Tesla has expanded the operational geofence for its driverless Robotaxi service in Austin, Texas, marking the first such increase in some time. The updated Service Area for Robotaxi in Austin now spans about 288 square miles and is roughly 9 percent larger than the previous boundary.
This incremental growth adds approximately 24 square miles of coverage, bringing the prior zone of roughly 264 square miles into a broader footprint that better serves northern suburbs.
The expansion extends the geofence northward toward Pflugerville along the US 183 corridor, incorporating additional neighborhoods north of the Domain and areas such as Mesa Park. These additions include higher-end residential and commercial districts that previously sat just outside the allowed operating zone.
Riders can now request unsupervised trips that begin or end in these newly included locations, provided the entire route remains inside the digital boundary:

Tesla first launched public Robotaxi operations in Austin in mid-2025 with a modest initial zone of about 20 square miles. Subsequent enlargements in 2025 and early 2026 steadily grew the map until it covered much of the metropolitan area.
After the last major update roughly ten months earlier, the company held the boundary steady while it collected additional miles and refined the FSD suite.
The modest nine percent increase still matters for daily utility. Longer trips become possible, more residents gain access, and the fleet can accumulate more diverse real-world data across new road types and traffic patterns. Observers note that the added territory aligns with existing Tesla service infrastructure, which could support more efficient vehicle staging in the North end of Austin.
Although the geofence has grown, Tesla continues to operate a relatively small unsupervised fleet in the city. The company has emphasized safety and software readiness over rapid geographic scaling. This latest map update signals that Tesla remains committed to expanding Robotaxi availability in its home market as it prepares for further software improvements and potential Cybercab deployments.
The 288-square-mile zone now gives Austin riders one of the larger driverless service areas currently available in the United States.
