We’ve now uncovered more details on how Tesla achieved such drastic improvements in the vehicle’s power consumption, which Tesla estimated to be a 40% reduction.
Tesla made architectural changes to how it processes and analyzes video — optimizing which components handle which tasks. While the Cybertruck is the first to benefit from these advancements, Tesla plans to extend these upgrades to other vehicles in the future.
Sentry Mode Power Consumption
Tesla vehicles feature two main computers: the MCU (Media Control Unit) computer, which powers the vehicle’s infotainment center, and the FSD computer, which is responsible for Autopilot and FSD. Both of these computers remain on and powered any time the vehicle is awake, consuming about 250-300 watts.
Typically, the vehicle only uses this power while it’s awake or actively driving. It’s not a major concern since the car automatically goes to sleep and shuts down its computers after about 15 minutes of inactivity. However, the larger issue is that these computers also need to remain on when Sentry Mode is active, causing a 250-watt draw whenever Sentry Mode is on.
Interconnected System
Today, the vehicle’s cameras are connected to the FSD computer, which connects to the MCU, which is finally connected to the USB ports. Because of this interconnected setup, everything needs to remain powered. Footage needs to be streamed from the FSD computer into the MCU, where processes like motion detection occur. The data then needs to be compressed before finally being written to the USB drive. That’s a lengthy process, requiring multiple computers to remain on in order to be able to record and save live video.
Architectural Changes
Tesla is making some architectural changes to address Sentry Mode’s high power consumption by shifting the responsibilities of the vehicle’s computers. By shifting motion detection and possibly the compression activity to the FSD computer, Tesla will now be able to keep the MCU computer asleep. The MCU is still required to push the video to the USB drive, but Tesla can now wake up the system only when it’s needed.
For instance, the FSD computer will still handle the connection to the vehicle’s cameras, but it will now also detect motion. When that Sentry event occurs, it can wake up the MCU to write the data to the USB drive and then have it go back to sleep.
This approach ensures the MCU isn’t continuously powered to analyze and compress video, instead activating it only when data needs to be written.
Processor Isolation & Task Allocation
Tesla’s current architecture separates the Autopilot Unit (APU) from the MCU. This is done for several reasons - but first and foremost is safety. The MCU can be independently restarted even mid-drive without impacting the APU and key safety features.
Additionally, by isolating the APU from the MCU, tasks that are optimized for each unit—processing versus image transcoding—can be offloaded to the processing unit that’s better suited for it. This helps keep both the APU and MCU operating at their optimal power and performance parameters, helping to manage energy consumption more efficiently.
Kernel-Level Power Management
Tesla’s been working on more than just FSD or new vehicle visualization changes and has been putting in the effort to optimize the operating system’s underlying kernel. While not in heavy use, Tesla is underclocking the processors of both the MCU and APU, reducing power usage and heat generation.
Of course, other kernel optimizations and programming tricks, such as the ones Tesla uses to optimize its FSD models, also factor into the increased overall efficiency of the vehicles.
Additional Benefits
Since Tesla vehicles also include a Dashcam that processes video, it’s possible we may also see these additional power savings whenever the vehicle is awake. This could also affect other features, such as Tesla’s Summon Standby feature, which keeps the vehicle awake and processing video to give users almost instant access to the vehicle’s Summon feature.
Roll Out to Other Vehicles
While the Cybertruck was the only vehicle to receive these power improvements to Sentry Mode, we were told that they’re coming to other vehicles too. Tesla is introducing these changes with the Cybertruck first, leveraging its smaller user base for initial testing before expanding the rollout to other vehicles.
USB Port Power Management
To further conserve energy and reduce waste, Tesla now powers down USB ports, even if Sentry Mode is active. This change has impacted many users who rely on 12v sockets or USB ports to remain powered to keep accessories such as small vehicle refrigerators on.
It’s not immediately clear whether these changes to Sentry Mode impact this change or whether power to 12v outlets was removed strictly due to safety concerns.

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.

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.
