Tesla Supercharger V3 details: 250 kW, no charge splitting, twice as fast

Published

on

Tesla launched its newest V3 Supercharger at an official unveiling event in Fremont, California, Wednesday night.

As we first reported, V3 Superchargers will be able to charge twice as fast the current generation Supercharger with a maximum power output of 250 kW or 1,000 miles per hour. Additionally, Tesla owners using V3 Superchargers will no longer need to split power with neighboring vehicles, thereby substantially increasing the charge rate and reducing the overall amount of charging time by nearly half.

Supercharger V3 details first surfaced Wednesday evening in Release Notes for a new over-the-air firmware update that went out to Model 3 owners, first captured by Erik @teslainventory on Twitter.

Tesla began to roll out the over-the-air firmware update to a small group of Model 3 owners that were invited to attend the official Supercharger V3 unveiling. Attendees are members of Tesla’s “Early Access Program” who will be one of the first to use Tesla’s next-generation Supercharger.

The firmware update went out ahead of the event to prepare these vehicles to accept the higher power output from Tesla’s newest ultra-fast chargers.

“Your Model 3 is now able to charge at V3 Superchargers at up to 250 kW peak rates. Supercharger stations with V3 hardware are designed to enable any owner to charge at the full power their battery can take – no more splitting power with another vehicle connected to your cabinet. This combination of higher peak power and dedicated vehicle power allocation across the site enables you to charge in half the time.”

Of note is the final sentence in the section for “Supercharger Improvements”, which indicates that the firmware update will allow a vehicle to condition its batteries before arriving at a V3 Supercharger station. “Also, when you navigate to a Supercharger, your call will condition its battery during the drive, so it can charge faster,” reads the release note.

Preconditioning a battery isn’t something new for Tesla vehicles, especially for P100D owners looking to ‘Bring it on!‘ with Ludicrous Mode. Being able to optimize the temperature of the battery cells allows them to be in a state that can operate at higher current and thereby charge at the higher 250 kW power.

At the moment, our understanding is that only Model 3, which utilizes a newer generation 2170 cell compared to the older 18650 form factor cell found in Model S and Model X, will be able to V3 Supercharge at full potential.

Be sure to check back as we will update the story with full details and specifications for Tesla Supercharger V3.

Update: Tesla published details for V3 Supercharging in a company blog post (included below). A video of the fast charging speed can be seen in their video.

Introducing V3 Supercharging

Tesla has more than 12,000 Superchargers across North America, Europe, and Asia and our network continues to grow daily: more than 99% of the U.S. population is covered by the network, and we anticipate similar coverage in Europe by the end of 2019. Recently, we passed 90% population coverage in China and are growing that number quickly. However, in order to drive continued electric vehicle adoption and further accelerate the world’s transition to sustainable energy, charging needs to be even faster, and the number of vehicles able to charge at a location in a day needs to be significantly higher. Today, we’re unveiling V3 Supercharging, the next step in the growth of Tesla’s Supercharger network. V3, which is born from our experience building the world’s largest grid-connected batteries, enables our vehicles to charge faster than any other electric vehicle on the market today.

Faster Charging, No More Power Sharing
V3 is a completely new architecture for Supercharging. A new 1MW power cabinet with a similar design to our utility-scale products supports peak rates of up to 250kW per car. At this rate, a Model 3 Long Range operating at peak efficiency can recover up to 75 miles of charge in 5 minutes and charge at rates of up to 1,000 miles per hour. Combined with other improvements we’re announcing today, V3 Supercharging will ultimately cut the amount of time customers spend charging by an average of 50%, as modeled on our fleet data.

Supercharger stations with V3’s new power electronics are designed to enable any owner to charge at the full power their battery can take – no more splitting power with a vehicle in the stall next to you. With these significant technical improvements, we anticipate the typical charging time at a V3 Supercharger will drop to around 15 minutes.

On-Route Battery Warmup
New Supercharging infrastructure isn’t the only way we are improving our customers’ charging experience. Beginning this week, Tesla is rolling out a new feature called On-Route Battery Warmup. Now, whenever you navigate to a Supercharger station, your vehicle will intelligently heat the battery to ensure you arrive at the optimal temperature to charge, reducing average charge times for owners by 25%.

This combination of higher peak power with V3, dedicated vehicle power allocation across Supercharger sites, and On-Route Battery Warmup enables customers to charge in half the time and Tesla to serve more than twice the number of customers per hour. Additionally, we are also unlocking 145kW charge rates for our 12,000+ V2 Superchargers over the coming weeks.

With Model 3 now shipping globally in high volumes and Model Y on the way, V3 Supercharging enables us to deliver the fastest production charging experience at an unprecedented scale compared to other electric vehicle manufacturers. By increasing the number of vehicles we’re able to charge at each Supercharger in a day, the investment we’re making in our network will go significantly further with every V3 station deployed. Paired with other savings, these efficiencies will translate to an increased pace of investment for Superchargers moving forward, with a continued focus on getting to 100% ownership coverage across all regions we operate. With thousands of new Superchargers coming online in 2019, the launch of V3, and other changes we’re making to improve throughput, the Supercharger network will be able to serve more than 2x more vehicles per day at the end of 2019 compared with today – easily keeping pace with our 2019 fleet growth.

Beginning today, we’re opening the first public beta site in the Bay Area, which will incrementally be made available to owners in Tesla’s Early Access Program. We’re launching V3 Supercharging for Model 3, our highest volume vehicle, and we’ll continue to expand access as we review and assess the results of millions of charging events. We will increase Model S and X charging speeds via software updates in the coming months. V3 Supercharging will roll out to the wider fleet in an over the air firmware update to all owners in Q2 as more V3 Superchargers come online. Our first non-beta V3 Supercharger site will break ground next month, with North American sites ramping in Q2 and Q3 before coming to Europe and Asia-Pacific in Q4.

Elon Musk rips ABC News over fatal NYC Tesla crash report

Musk pushed back on NYC Tesla crash coverage, pointing to a pattern of premature blame.

Published

on

By

Elon Musk pushed back overnight against media framing of a fatal Tesla crash in Midtown Manhattan, telling a user on X that “it wasn’t the car” and that the vehicle’s Autopilot system had nothing to do with the wreck.

The crash happened just before 3 a.m. Wednesday, when a 2024 Tesla Model Y struck a sidewalk shed outside 315 Madison Ave., a bus stop pole and a mailbox on East 42nd Street, according to the NYPD. The car kept moving several more blocks before stopping near Second Avenue. Both women inside, each 27, were taken to Bellevue Hospital, where the passenger was pronounced dead. The driver was charged with vehicular manslaughter, driving while ability impaired and leaving the scene of an accident.

Police have not attributed the crash to Autopilot or Full Self-Driving in any public statement. The charges point to impairment, not software. Musk’s response followed a since-deleted ABC News post that he said mischaracterized the incident. Replying to a user on X, Musk wrote that if Autopilot had been engaged, “they would not have crashed,” and added that “the legacy media will never forgive Tesla for failing to advertise with them,”

It’s a familiar cycle for Tesla. In June, headlines from several national outlets described a fatal crash in Katy, Texas, as happening while the car was “on autopilot,” based on the driver’s own account to police after his Model 3 struck a home and killed a 76-year-old woman. Tesla’s data told a different story when Ashok Elluswamy, Tesla’s head of AI, said the driver had pressed the accelerator to 100% and reached 73 mph in a residential zone. Harris County prosecutors later confirmed the human override and the driver was charged with manslaughter.

Florida Gov. Ron DeSantis pointed to that same Katy crash last month to argue that outlets routinely name Tesla in crash headlines while leaving other automakers unnamed, even after a driver’s own actions are shown to be the cause. A similar pattern played out in 2024, when Musk had to clarify that FSD was never even downloaded onto the Model 3 involved in a fatal Colorado DUI crash, despite a passenger’s claim that an “auto drive feature” was in use.

Tesla has not issued a separate statement on the Manhattan crash beyond Musk’s posts on X. The NYPD’s investigation is ongoing, and no cause for the driver losing control has been released.

Tesla’s two defunct flagship models are getting a big upgrade

Published

on

Tesla’s two recently-defunct flagship models, the Model S and Model X, are getting a big upgrade, according to the company’s Head of AI, Ashok Elluswamy.

Older Hardware 3 Model S and Model X vehicles have been the last major holdouts in Tesla’s Full Self-Driving v14 Lite rollout, and that wait now appears to be ending.

Tesla brings closure to flagship ‘sentimental’ models, Musk confirms

At Tesla’s Cybercab launch, AI chief Ashok Elluswamy told Ryan McCaffrey that he thought the S and X build “was supposed to go out last week.” Evidently, Elluswamy expects the suite to be rolled out to those HW3 Model S and Model X very soon:

Those cars are not the current Model S and Model X, which already ship with Hardware 4. They are the pre-refresh flagships built around Tesla’s older Autopilot computer, often called HW3 or AI3.

Tesla stopped putting that computer in new vehicles years ago, which is why owners treat these S and X cars as a closed generation. Model 3 and Model Y vehicles on the same computer began receiving v14 Lite in late June 2026 and saw a wider North American expansion in July. South Korea followed as an early international market. The S and X versions of the same software never joined that wave.

v14 Lite is Tesla’s way of squeezing the current v14 driving stack onto hardware that cannot run the full AI 4 model. The company describes the process as distillation: behaviors learned on the newer computer, including reinforcement learning and offline models, are compressed so the older chip and cameras can use them as a guide.

Early descriptions put the distilled network at roughly 15 percent of the original size. The result is still supervised Level 2 driving. Tesla has been clear that HW3 cannot support unsupervised Full Self-Driving or robotaxi operation because of memory and bandwidth limits.

The feature list is what made the wait so frustrating for S and X owners, as plenty of new features are to be shipped with it.

Official notes for the first Lite build, firmware 2026.20.5.1, added parking, unparking, and reversing; arrival options for a parking lot, street, driveway, or curbside; speed profiles that stay available at all times; and start-from-park engagement. Tesla also claimed better handling of merges, forks, pedestrians, traffic lights, and cut-ins, plus fewer false slowdowns and smoother lane centering.

A mid-July follow-on build, 2026.20.6.10, added more of the Hardware 4 interface, including a standalone Self-Driving app and the ability to start a trip from Park without a brake-pedal confirmation.

Elluswamy called that version the one “likely going to wide release.”

That wide release already reached most other HW3 cars in the United States and Canada. International timing still depends on regional validation and regulatory approval. For S and X owners, the remaining work appears to be model-specific validation rather than a new software stack.

There is no official Tesla changelog or build number for those two models yet, only Elluswamy’s offhand timeline. Some HW3 drivers who already have Lite report large gains over v12.6; others have described new indecision or phantom braking. The next test will be whether the same software lands cleanly on the older flagships that have waited the longest.

This tiny Tesla Cybertruck adjustment has big advantages

Published

on

Yesterday, we reported on Tesla Cybertruck getting some major adjustments from a manufacturing standpoint in an effort to make the all-electric pickup more cost-effective, more reliable, more serviceable, and more easily produced.

Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup

One of those changes was the addition of a self-reinforcing polypropylene aero shield that sits underneath the truck. Previously, Tesla utilized aluminum for this, but the self-reinforcing polypropylene was more durable while also being cheaper and lighter.

Tesla has revealed another small change it made to the Cybertruck, and it has to do with the side repeater cameras.

Tesla does not wait for a new model year to improve its vehicles. On September 8, Cybertruck lead engineer Wes Morrill posted side-by-side photos of an updated side repeater camera housing now rolling off the line at Gigafactory Texas.

The triangular camera pod mounted on the front fender looks almost identical at first glance. A closer look reveals a revised contour that uses the air already flowing around the truck to keep the lens clearer in rain and road spray.

The side repeater cameras sit in an exposed position on the Cybertruck’s angular stainless-steel body.

In wet weather, they readily collect water droplets that can degrade the image Autopilot and Full Self-Driving use for lane changes and blind-spot monitoring. Early production trucks sometimes left owners wiping lenses by hand or accepting temporary restrictions on driver-assistance features.

Tesla has added washers to cameras on certain other models and on Cybercab prototypes, but those active systems add cost, complexity, and extra potential leak points.

The new housing solves the problem with passive geometry. Subtle changes in the surround create localized airflow disturbances as the vehicle moves. Those eddies physically push water droplets away from the optical surface. Morrill called the result “pure vision improvement” achieved at “no cost penalty.” Once the production mold is updated, every subsequent part costs the same as the original.

The advantages compound quickly. Clearer cameras in rain improve the reliability of driver-assistance features precisely when they are needed most. The design consumes no extra energy and introduces no new failure modes.

New Cybertrucks built after the tooling changeover receive the updated part automatically. Some owners of trucks delivered as late as June 2026 have already confirmed they received the revised housing. Retrofit questions have appeared in replies, and the cameras appear electrically compatible, though Tesla has not announced an official service program.

A few millimeters of reshaped housing will not make headlines the way a new battery pack does, but these changes are incremental and increase the Cybertruck’s effectiveness as a vehicle over time.

This improvement illustrates how Tesla continues to refine the Cybertruck after volume production began. Better wet-weather vision, zero added cost, and no extra hardware add up to a meaningful gain in everyday usability and safety.
