Tesla was pretty light on the specifications and details behind the vehicles, but there was some information that made its way out to the open in the following days. We’ve gathered up all that juicy information, so leave your Supercharger cable behind, and let’s take a look at some Cybercab battery and range details.
In addition to Tesla Vision, Optimus leverages many of our vehicles' hardware components, like batteries, cameras & computers
Tesla released this excellent animation on X recently, which looked at the similarities between Optimus - Tesla’s humanoid robot - and the Cybercab. The key note is that the Cybercab and Optimus share the same batteries, same computer, and same cameras, all based on AI5. So, assuming the video is accurate, we can roughly determine how many batteries are inside the Robotaxi, and then extrapolate the range as well. We’ve also got a second method to take estimate the vehicle’s battery size, based on the video where Tesla showed off the Cybercab’s wireless charging capabilities.
Method 1: Counting Batteries
Based on the animation, the grid of cells is 27 wide by 30 tall. If the video accurately depicts the Cybercab’s battery pack, that gives us 810 cells. We already know the 4680 battery pack in the Cybertruck has 1,344 cells, with a capacity of 123 kWh.That’s about 0.09kWh per cell, which works out to 74.685kWh in the Cybercab.
However, we feel that this number is far too large, especially given that Tesla is already intending to use the new NC05 battery format in the Cybercab. We expect the Cybercab to launch with a battery smaller than the Model 3 Standard Range (54 kWh). Therefore, we can try a different method to determine the pack size.
Method 2: Charging Math
Rafael Levy on X helped out with this calculation - it's possible to extrapolate the battery size in the Cybercab by looking at the charge rate, time remaining, and battery max charge level in Tesla’s wireless charging video. In the video, the car starts charging at 35% and is being charged at about 25 kW. The video shows the charger starting at 19 kW and going up to 25 kW of power. The video also shows that the vehicle is charged for 56 minutes. Near the end of the video the vehicle finishes charging at 80% - likely suggesting a non-LFP battery.
When you calculate it out - 25 kW for 56 minutes, you get 23.3 kWh, which is 45% of the battery pack (35% to 80%). Calculating for the full pack, it sounds like the Cybercab’s battery pack is approximately 51kWh, a much more reasonable number.
We expect the Cybercab to launch with the new NC05 cells that Tesla has been working on, which will likely be a smaller, more efficient cell than the Cybercells in today’s Cybertruck. Those smaller cells will also have less energy per cell while also taking up less space and being easier to warm or cool due to overall thermal mass.
The Cybercab doesn’t need to solve every travel case, just the most popular, which would be shorter distances. Tesla’s goal with the Cybercab is efficient and cost-effective, and a smaller battery pack definitely fits into that motive. We expect the Cybercab to include between a 40 kWh and 50 kWh battery pack.
Being autonomous, the Cybercab will have more opportunities to charge and clean itself without inconveniencing the consumer since it could go to a nearby hub after dropping off a customer.
Cybercab / Robotaxi Range
Yesterday, Tesla shared its Q3 earnings call deck, which revealed some new information about the Cybercab. In it, Tesla stated that the Cybercab will include a new powertrain and will achieve an estimated 5.5 miles per kWh. For reference, the Model 3 Long Range gets about 3.9 miles per kWh, so this is a massive improvement. Some of the improvements likely lie in the Cybercab's lighter weight and improved aerodynamics, but the new powertrain likely also brings some increased efficiency.
If the Cybercab achieves 5.5 miles per kWh, we can speculate that, depending on the battery pack size, it’ll have a range between 220 and 270 miles.
Top Gear also attended the Robotaxi event and was told by an employee that Tesla is aiming for a vehicle with 200 miles of range, which matches the lower end of our calculations above. Top Gear also stated at the time that the Cybercab would achieve 5.5 miles per kWh, which Tesla revealed yesterday.

Following customer requests, Tesla has once again returned FSD Transfers for North America. This comes after some new details we received on FSD Supervised and Unsupervised at the recent Q1 2025 Earnings Call.
Vox Populi, Vox Dei … FSD Transfer is back
All countries (in NA), all S3XY + @cybertruck (excl Foundation Series & Launch Series)
This latest round of FSD transfers doesn’t have a specific time limit - so if you’re in the market for a new vehicle and were worried about transferring FSD from a HW3 vehicle - now is the best chance.
This transfer opportunity is applicable for any new vehicle purchases, including the Model S, 3, X, Y, as well as the Cybertruck. The only vehicles it doesn’t apply to are the Foundation-Series Cybertruck or a Launch-Series Model Y, which already come with FSD included.
If you’re conducting an FSD transfer, you’ll need to reach out to your Tesla delivery coordinator through the Tesla app to confirm you’re eligible and to get the process started.
Note that once you take delivery, FSD access is removed from your older vehicle, regardless if you plan to trade in your vehicle or keep it.
Canada and Mexico
For those in Canada and Mexico, there’s some good news. This opportunity is available for customers in those countries as well, however, new vehicle orders are currently paused in Canada and Mexico for unknown reasons.
Running Offers
There are also several other offers running in North America, with the country flags indicating which countries their available in:

Tesla’s long-awaited ambitions for a fully autonomous Robotaxi network powered by the futuristic, control-less Cybercab have finally started to take shape.
During their Q1 2025 earnings call, Tesla shared new details about its Robotaxi network, including that the network will start with new Model Ys. The Cybercab will join the network in 2026.
Robotaxi Plans
Tesla confirmed during the Earnings Call that it is on track to conduct the pilot launch of its Robotaxi network in Austin in June 2025. The first vehicles deployed for this service won’t be Cybercabs, as production for those is still in the prototyping stage.
However, Tesla did outline part of their plan for the Robotaxi network rollout. The initial aim is to begin driverless operations in Austin and then expand the service to other cities within the United States by the end of 2025. Interestingly, Tesla is also testing in California - albeit with safety drivers at this time.
Not a Tesla App
Looking further ahead, there are ambitious plans to ramp up operations to have millions of vehicles operating autonomously within the network by the end of 2026. While substantial revenue generation won’t be immediate, Tesla anticipates that the Robotaxi network will start to “meaningfully move the financial needle” in the second half of 2026.
Tesla also highlighted the current real-world benefits that FSD is already offering today—and will be able to offer to many more people in the near future.
These include reducing effort and time spent on daily commuting or transit, as well as improving mobility for customers with disabilities. Tesla plans to emphasize some of these community stories and wants to highlight the advantages and capabilities of FSD to improve people’s lives.
Robotaxi App and Robotaxi Vehicle UI
Not a Tesla App
After the call, Tesla AI also shared a video showcasing the Robotaxi interface in the Tesla app, as well as some footage that included the in-vehicle UI, at least as it currently stands.
The video shows Tesla employees using and testing Robotaxi features, although there are safety drivers in place. It looks like there is already a set of well-integrated UI mechanisms for both the front and rear screen when in Robotaxi mode.
Tesla is testing this today, and this network has already completed 1,500 trips, totaling approximately 15,000 miles. The system is being tested for vehicle allocation, mission control, and remote assistance operations.
Remote Operators
Inevitably, edge cases or unique situations will come up, and they will be difficult to handle. For these cases, where a Robotaxi vehicle gets stuck or requires assistance, Tesla will likely implement remote support.
While they didn’t completely confirm remote support operators on the Earnings Call, Tesla has previously posted positions for Teleoperator Engineers for Robotaxi, and an AI T=team member posted on LinkedIn about testing for remote assistance operations.
Scaling Up
Tesla initially intends to deploy a relatively small fleet in Austin, with its pilot beginning with about 10 to 20 vehicles on day 1. They will scale up gradually as the systems are validated and operations are refined, and the target is for anyone visiting Austin to be able to hail a robotaxi by the end of June or early July 2025.
Scaling Out
Not a Tesla App
Tesla’s confidence in scaling out stems from its generalized approach with FSD. The team believes that once FSD is thoroughly verified and capable in a few diverse North American cities, deploying it to any other North American city should be technically feasible. After all, driving regulations don’t vary much from one major city to another, except for things like no right turns on red lights.
The primary limitation with scaling out geographically is expected to be securing regulatory approvals in different regions and jurisdictions. While the principles of Tesla’s FSD are expected to apply globally, as with the China rollout, regulation will continue to be a considerable hurdle.
Cybercab

Tesla’s fully autonomous, two-seater vehicle, the Cybercab, is also being developed. While volume production for the Cybercab won’t begin until 2026, Tesla is already undergoing sample production validation. The first actual Cybercab builds are expected to be completed near the end of Q2 2025, and we’re excited to see if anything changes from the prototypes shown at We, Robot.
Tesla intends to build Cybercab at Giga Texas, and the production line is on schedule, according to Tesla. Cybercab production will not require a new building and will be built inside the existing Giga Texas factory.
Unboxed Method
Tesla's Shareholder Deck for Q1 2025 is now out, and we're 40 minutes away from the Earnings Call.
It seems Tesla won't be using the unboxed process for its more affordable model - which is a new vehicle.
The Cybercab’s production and low-cost methodology heavily rely upon Tesla’s innovative new unboxed manufacturing method. Tesla’s executive team mentioned that progress and implementation with this new manufacturing solution was going well, and it will be key to lowering the cost of production while considerably raising the level of automation.
Tesla has already achieved key milestones with this method, including successfully integrating large sub-assemblies and resolving challenges related to connecting portions of the vehicle's ceiling during the process. They have also successfully completed corrosion testing related to the new assembly method, as well as begun initial crash testing for the Cybercab.
All of that and more will eventually be incorporated into other vehicle production lines, and the Cybertruck is already benefiting from some aspects of these developments. With a final ambition of achieving a 5-second cycle time per Cybercab, Tesla has come a long way—but it still has quite a bit to go. They’ve managed to meet a 33-second cycle time for the Model Y at Giga Shanghai between two production lines, but 5 seconds per vehicle is quite ambitious.
Not a Tesla App
With all that said, between Robotaxi and Cybercab, there is a lot of interesting news coming from Tesla. We expect this to continue throughout the year as Tesla launches its network and then aims to release FSD Unsupervised to customers, with a potential price increase.
