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 improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
