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 flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.
The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.
Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990
Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.
However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.
Multi-Row Climate Control
Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility
One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.
Tesla has improved upon this with the Model Y L:

PowerShare will be included
Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.
Wireless Charging Pad
There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.

Tesla owner fixes common feature complaint with crafty DIY retrofit
Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.
Thermal Management Improvements
These improvements in the Model Y L were seen with thermal management:
- Up to 15% faster cabin cooling
- +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
- 8x more solar energy reflection off of glass roof
- 30% reduction in solar energy entering the cabin

Tesla CEO Elon Musk took to his social media platform X on Thursday night to deny a ridiculous rumor regarding the sale of the company’s Chinese vehicle production plant, Gigafactory Shanghai.
On Thursday, the Wall Street Journal, citing sources familiar with the matter, claimed in a scathing new report that Tesla was exploring a potential sale of the entire China business in an effort to help bolster a potential merger between SpaceX and Tesla.
Musk immediately denied the rumor not once but twice, initially calling it “fake news,” and then calling it “absurdly fake news” in a separate post just a few moments later:
This is fake news
— Elon Musk (@elonmusk) July 31, 2026
The original poster of the Wall Street Journal article that Musk saw deleted the initial post sharing the headline and the rumored sale of Tesla’s China business.
This has never even come up in a discussion ever.
Absurdly fake news.
-People should assume news is fake until proven otherwise.
— Elon Musk (@elonmusk) July 31, 2026
The report seemed absolutely and unequivocally false to begin with; Tesla’s business in China is among the most important pieces of the company’s business. Not only does the factory supply vehicles for the domestic market, but also for various other markets in Asia and Europe.
China is also one of the largest automotive markets in the world, and Tesla has performed well there despite the robust competition.
The speculation regarding a Tesla and SpaceX merger has started to gain steam this year as the space exploration company went public just a month ago. There has been speculation that Musk will bridge all of his companies under one “umbrella company,” and analysts believe this could happen before the end of the decade.
The Tesla and SpaceX merger everyone is talking about is quietly building

This is the latest iteration of Musk’s very evident war on mainstream media. Reports regarding any of Musk’s companies are quick to get the dreaded “false” or “fake news” response from the CEO when they are unfounded.

Tesla AI boss reveals how big Optimus is going to get
Tesla’s Optimus chief corrected himself on X, confirming a staggering 10 million robot production target.
![Tesla Optimus Gen 3 [Credit: Tesla]](https://www.teslarati.com/wp-content/uploads/2026/03/tesla-optimus-gen3-diner.jpg)
Tesla’s Optimus program has a new number attached to it, after Ashok Elluswamy, the executive who has run the humanoid robot program since June 2025, posted a three word correction on X Thursday, “Correction, 10 million robots.”
The line clarifies the long term annual capacity Tesla is building toward its planned second Optimus production line at Gigafactory Texas, a figure Musk has cited repeatedly since last year’s shareholder meeting.
The scale is worth noting, because ten million robots a year would mean Tesla building more units annually than most countries sell in new cars. Tesla has framed this as a second line, not the first. The buildout is happening in two phases: a roughly one million unit per year line inside Tesla’s Fremont factory, installed on the floor space vacated when Model S and Model X production ended earlier this year, and a much larger dedicated facility under construction at Giga Texas that broke ground on its first steel structure in May. That Texas facility is the one Elluswamy’s correction refers to, and is expected to reach volume production sometime in 2027.

Tesla Optimus project fires up as Musk sees production line progress
Elluswamy took over Optimus from Milan Kovac last summer and has spent the months since talking up the program’s trajectory. Elon Musk has also floated the ten million figure at Tesla’s 2025 shareholder meeting.
-
Ending Model S and Model X production to make room for the first Optimus line was one of the more consequential manufacturing decisions in the company’s recent history, retiring two flagship vehicles in favor of a robot that has yet to enter mass production. Musk has previously estimated per unit production costs at $20,000 to $25,000 once Tesla reaches a million units a year, though he hasn’t said what that cost looks like at ten times the volume.
