The newly built Model Y 4680 battery packs are seeing an impressive and positive (pun intended) charging speed.

According to Twitter user The Kilowatts, they were able to charge their new Model Y from 0% to 97% in just 52 minutes.

The Kilowatts’s Ryan Levenson took delivery of an Austin, Texas-made dual-motor Model Y, which is built with Tesla’s highly anticipated 4680 battery pack.

Levenson rents out electric vehicles he owns on Turo and maintains them. Levenson shared on Twitter that he drove the new Model Y three miles past its 0% state of charge. He noted that there was no effect on the vehicle’s acceleration.

“0% -> 97% in 52 minutes for our MIT (made in Texas) Dual Motor Model Y,” Levenson writes on Twitter.

“Plugged in at 12:25 am with 0 miles of range remaining (actually drove 3 miles beyond 0 with seemingly no impact on acceleration). Unplugged at 1:17 am with 270 miles of range.”

Levenson noticed that by plugging into a V3 supercharger, the vehicle almost immediately ramped up to the 250kW charging rate, which is much different than Tesla’s current battery packs that take time to ramp up to the 250kW rate.

“For anyone trying to analyze the charge curve here, it seems quick but what I find most interesting is the almost immediate jump to ~250kW unlike the ramp up to 250kW we’re used to and from there it slowly tapers down throughout the charge cycle.”

Tesla’s currently listing the Model Y dual motor configuration to have a total of 279 miles of EPA-rated range.

Being able to drive past 0% state of charge is interesting. Tesla purposely builds in a little buffer to err on the side of caution when estimating the remaining range.

Tesla does software lock the range on its vehicles to prevent them from losing all of their charge and damaging the battery.

In order to meet manufacturing efficiencies, Tesla has previously shipped vehicles with larger batteries and software-locked them if an owner bought a model with a shorter range.

Although the owner can only access the portion of the battery that they paid for, they actually receive a couple of hidden benefits.

The car can be charged to "100%" every day without any ill effects since the battery itself is not charged to 100%, only the portion the owner paid for.

Another advantage of such models is that the owner can buy and unlock the additional range at a later date if they choose to.

In 2019, during Hurricane Dorian in Florida, Tesla remotely extended the ranges on such vehicles so they could escape Dorian’s path.

They also provided Tesla drivers with free supercharger access and force-charged the Powerwall batteries to full power so they would be ready in case of a severe power outage.

Tesla’s battery day event back in September 2020 unveiled some pretty impressive technologies coming, but Tesla has yet to share in-depth data on what we can expect in real-world scenarios.

Tesla Preparing to Expand Robotaxi Geofence As Validation Vehicles Spotted

By Karan Singh
Not a Tesla App

Tesla appears to be preparing to expand its Robotaxi geofence in Austin, Texas, with numerous engineering vehicles taking to the road. One of the most interesting sights, between the short and tall LiDAR rigs, was a Cybertruck validation vehicle, which we don’t often see.

Tesla’s expansion is moving the Robotaxi Network into downtown Austin, a dense urban environment that is currently outside the geofence. It appears Tesla is content with the latest builds of Robotaxi FSD and is ready to take on urban traffic.

The inclusion of a Cybertruck in the validation fleet is noteworthy, as the rest of the vehicles are Model Ys. This suggests that Tesla may be addressing two challenges simultaneously: expanding its service area while also addressing the FSD gap between the Cybertruck and other HW4 Tesla vehicles.

Using LiDAR

Recent sightings have shown a fleet of Tesla vehicles, equipped with rooftop validation sensor rigs, running routes throughout downtown Austin and across the South Congress Bridge. While these rigs include LiDAR, it’s not a sign that Tesla is abandoning its vision-only approach.

Instead, Tesla uses the high-fidelity data from the LiDAR as a ground truth measurement to validate and improve the performance of its cameras. In short, it essentially uses the LiDAR measurements as the actual distances and then compares the distances determined in vision-only to the LiDAR measurements. This allows Tesla to tweak and improve its vision system without needing LiDAR.

Additionally, the validation vehicles are likely scouting for the new, pre-determined, selectable pick-up locations that have just rolled out as part of the Robotaxi app.

Expanding the Geofence

This data collection in a new, complex environment right outside the Robotaxi geofence is an indicator that plans to expand the geofence. Tesla has previously indicated that they intend to roll out more vehicles and expand the geofence slowly. Given that their operational envelope includes the entire Austin Metro Area, we can expect more locations to open up gradually.

Once they expand the operational radius to include downtown Austin, they will likely also have to considerably increase the number of Robotaxis active in the fleet at any given time. Early-access riders are already saying that the wait time for a Robotaxi is too long, with them sometimes having to wait 15 minutes to be picked up.

With a larger service area, we expect Tesla to also increase the number of vehicles and the number of invited riders to try out the service.

After all, Tesla’s goal is to expand the Robotaxi Network to multiple cities within the United States by the end of 2025. Tesla has already been running an employees-only program in California, and we’ve seen validation vehicles as far away as Boston and New Jersey, on the other side of the country.

Cyber FSD Lagging Behind

One of the most significant details from these recent sightings is the presence of a Cybertruck. Cybertruck’s FSD builds have famously lagged behind the builds available on the rest of Tesla’s HW4 fleet. Key features that were expected never fully materialized for the Cybertruck, and the list of missing features is quite extensive.

  • Start FSD from Park

  • Improved Controller

  • Reverse on FSD

  • Actually Smart Summon

It may not look like a lot, but if you drive a Cybertruck on FSD and then hop in any of the rest of Tesla’s HW4 vehicles, you’ll notice a distinct difference. This is especially evident on highways, where the Cybertruck tends to drift out of the lane, often crossing over the lane markings.

We previously released an exclusive mentioning that a well-positioned internal source confirmed with us that a new FSD build for the Cybertruck was upcoming, but we never ended up receiving that particular build, only a point release to V13.2.9. The AI team’s focus had clearly shifted to getting the latest Robotaxi builds running and validated, and while a flagship, the Cybertruck fleet was small and new, and really a secondary task.

The Cybertruck’s larger size, steer-by-wire, rear-wheel steering, and different camera placements likely present a bigger set of challenges for FSD. Deploying it now as a validation vehicle in a complex environment like downtown Austin suggests that Tesla is finally gathering the specific data needed to bring the Cybertruck’s capabilities up to par. This focused effort is likely the necessary step to refine FSD’s handling of the Cybertruck before they begin rolling out new public builds.

When?

Once Tesla’s validation is complete, we can probably expect the Robotaxi Network to expand its borders for the first time in the coming days or weeks. However, we’ll likely see more signs of the expansion, such as Robotaxi vehicles driving themselves around the area, before the expansion actually happens.

Hopefully, the Cybertruck will also learn from its older siblings and receive the rest of its much-needed FSD features, alongside an FSD update for the entire fleet.

Tesla Updates Robotaxi App: Adds Adjustable Pick Up Locations, Shows Wait Time and More [VIDEO]

Tesla is rolling out a fairly big update for its iOS and early-access-only Robotaxi app, delivering a suite of improvements that address user feedback from the initial launch last month. The update improves the user experience with increased flexibility, more information, and overall design polish.

The most prominent feature in this update is that Tesla now allows you to adjust your pickup location. Once a Robotaxi arrives at your pickup location, you have 15 minutes to start the ride. The app will now display the remaining time your Robotaxi will wait for you, counting down from 15:00. The wait time is also shown in the iOS Live Activity if your phone is on the lock screen.

How Adjustable Pickups Work

We previously speculated that Tesla had predetermined pickup locations, as the pickup location wasn’t always where the user was. Now, with the ability to adjust the pickup location, we can clearly see that Tesla has specific locations where users can be picked up.

Rather than allowing users to drop a pin anywhere on the map, the new feature works by having the user drag the map to their desired area. The app then presents a list of nearby, predetermined locations to choose from. Once a user selects a spot from this curated list, they hit “Confirm.” The pickup site can also be changed while the vehicle is en route.

This specific implementation raises an interesting question: Why limit users to predetermined spots? The answer likely lies in how Tesla utilizes fleet data to improve its service.

Release Notes

While the app is still only available on iOS through Apple’s TestFlight program, invited users can download and update the app.

Tesla included these release notes in update 25.7.0 of the Robotaxi app:

  • You can now adjust pickup location

  • Display the remaining wait time at pickup in the app and Live Activity

  • Design improvements

  • Bug fixes and stability improvements

Why Predetermined Pick Up Spots?

The use of predetermined pickup points is less of a limitation and more of a feature. These curated locations are almost certainly spots that Tesla’s fleet data has identified as optimal and safe for an autonomous vehicle to perform a pickup or drop-off.

This suggests that Tesla is methodically “mapping” its service area not just for calibration and validation of FSD builds but also to help perform the first and last 50-foot interactions that are critical to a safe and smooth ride-hailing experience.

An optimal pickup point likely has several key characteristics identified by the fleet, including:

  • A safe and clear pull-away area away from traffic

  • Good visibility for cameras, free of obstructions

  • Easy entry and exit paths for an autonomous vehicle

This change to pick-up locations reveals how Tesla’s Robotaxi Network is more than just Unsupervised FSD. There are a lot of moving parts, many of which Tesla recently implemented, and others that likely still need to be implemented, such as automated charging.

Frequent Updates

This latest update delivers a much-needed feature for adjusting pickup locations, but it also gives us a view into exactly what Tesla is doing with all the data it is collecting with its validation vehicles rolling around Austin, alongside its Robotaxi fleet.

Tesla is quickly iterating on its app and presumably the vehicle’s software to build a reliable and predictable network, using data to perfect every aspect of the experience, from the moment you hail the ride to the moment you step out of the car.
