Tesla recently rolled out power efficiency improvements to its Sentry Mode feature for the Cybertruck with software update 2024.38.4. These updates drastically improve the vehicle’s power consumption when Sentry Mode is active.

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 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.

Tesla Will Face $2 Billion in Lost Profit as 'Big Beautiful Bill' Kills EV Credits

By Karan Singh

The massive legislative effort titled the "Big Beautiful Bill" is taking direct aim at what has become one of Tesla’s most critical and profitable revenue streams: the sale of US regulatory credits. The bill could eliminate billions of dollars from Tesla’s bottom line each year and will slow down the transition to electric vehicles in the US.

The financial stakes for Tesla are absolutely immense. In 2024, Tesla generated $2.76 billion from selling these credits. This high-margin revenue was the sole reason Tesla posted a profit in Q1 2025; without the $595 million from regulatory credits, Tesla’s reported $409 million in profit would have been a $189 million loss.

How the ZEV Credit System Works

Zero-Emission Vehicle (ZEV) credits are part of state-level programs, led by California, designed to accelerate the adoption of electric vehicles. Each year, automakers are required to hold a certain number of ZEV credits, with the amount based on their total vehicle sales within that state. Under this system, automakers that fail to sell a certain percentage of zero-emission vehicles must either pay a significant fine or purchase credits from a company that exceeds the mandate.

Automakers who fail to sell enough EVs to meet their quota have a deficit and face two choices: pay a hefty fine to the state government for each missing credit (for example, $5,000 per credit in California) or buy credits from a company with a surplus.

As an all-EV company, Tesla generates a massive surplus of these credits. It can then turn around and sell them to legacy automakers at prices cheaper than the fine, creating a win-win scenario: the legacy automaker avoids a larger penalty, and Tesla gains a lucrative, near-pure-profit revenue stream. 

This new bill will dismantle this by eliminating the financial penalties for non-compliance, which would effectively make Tesla’s credits worthless. While the ZEV program is a state law, the Big Beautiful Bill will fully eliminate the penalties at a federal level.

A Multi-Billion Dollar Impact

The removal of US ZEGV credits would be a severe blow to Tesla’s financials. One JPMorgan analyst estimated that the move could reduce Tesla’s earnings by over 50%, representing a potential annual loss of $2 billion. While Tesla also earns similar credits in Europe and China, analysts suggest that 80-90% of its credit revenue in Q1 2025 came from US programs. 

Why the Program Exists

While the impact on Tesla would be direct and immediate, the credit system has a wider purpose. It creates a strong financial incentive for legacy automakers to develop and accelerate their zero-emission vehicle programs, whether it’s hydrogen, electric, or another alternative.

Eliminating the need for these credits would remove that financial pressure. This could allow traditional automakers to slow their EV transition in the US without the fear of a financial penalty, potentially leading to fewer EV choices for consumers and a slower path to vehicle electrification in the country.

Big, But Not Beautiful

On Sunday Morning TV, Elon Musk was asked his thoughts on the Big Beautiful Bill. They were pretty simple. A bill could be big, or it could be beautiful - I don’t know if it can be both, Musk stated.

The bill poses a threat to Tesla’s bottom line and to the adoption of EVs in the US market, where automakers will no longer have a financial incentive to transition to cleaner vehicles, a market they’ve regularly struggled in when competing against Tesla.

Tesla will have to work carefully in the future to cut expenses to remain profitable after the elimination of these regulatory credits.
