Yesterday, Tesla released FSD v12.5.4 with update 2024.27.25. The update includes improvements to Tesla’s vision-based attention monitoring and Actually Smart Summon. This update initially rolled out to early-access testers yesterday, but since then, it has rolled out to more users, with the latest wave coming just moments ago.
This update includes more than just FSD bug fixes, so let’s take a look at what’s changed.
Actually Smart Summon Improvements
Actually Smart Summon is now officially known as Actually Smart Summon (Supervised), as per Tesla’s latest video on X (see it below). When Tesla released Actually Smart Summon, it added support for Tesla Vision, live camera feeds, and additional options.
Range Increase: Now, Tesla has brought even more improvements to the table. To start, Actually Smart Summon has had its range increased by about 50 feet – for a total range of 279 feet, or 85 meters. This also comes alongside a few new features, including completion and abort sounds.
Sounds: You can now choose to have the vehicle play a sound when Summon completes successfully. You can select from several – including Applause, “Ta Da,” “Ba-dum Tiss,” and Random. For now, unlike with your vehicle lock sounds, you can’t customize it just yet. To play summon sounds, your vehicle will need a functional Pedestrian Warning Speaker, or PWS. The abort sound only has one option right now – Emissions. Tesla’s engineers love their fart jokes.

Sadly, Actually Smart Summon is also missing a couple of features—HomeLink compatibility isn’t available for Summon, and Tesla says it's coming soon. The Side Clearance option, which previously let you choose between Standard and Tight clearances, is also gone.
For now, you’re also required to use Continuous Press to summon your vehicle. Usage without Continuous Press is coming soon though.
Actually Smart Summon Requirements
This new version of Actually Smart Summon also comes with some interesting requirements. Just like with previous versions, the doors, tailgate, and frunk must be closed before the vehicle is moved. However, the vehicle must also have a TPMS PSI of 34 or higher (on a Model 3 – this is likely the optimal PSI for your vehicle’s standard tires).
You’ll also need a Tesla app update – v4.37.0 is now the required version, which is currently available for iOS, but not available yet in the Google Play store..
The tire pressure requirement could be a big change, especially as many people who use aftermarket winter tire sets don’t run TPMS units. If you don’t have TPMS sensors in your tires, you may not be able to use Actually Smart Summon at all.
The second major update with 2024.27.25 is for Vision-Based Attention Monitoring. Vision monitoring allows FSD to function without users constantly having their hands on the wheel. Instead, it monitors the driver’s eyes to see if they’re paying attention.
Previously, this was limited to users not wearing sunglasses, although Tesla said the functionality to support sunglasses use would be coming soon. With this update, users can wear sunglasses and enjoy no-nag Full Self Driving.
This is a major update, as one of the biggest consternations with FSD V12.5 was that while vision monitoring was fantastic, it wasn’t always available to the driver if they wanted to wear sunglasses.
An undocumented change for vision monitoring is that if it detects a device—such as a cellphone—in your hand, it will say “Attention Monitoring unavailable—Detected device in hand.” This popped up when the user, @WifeDirtyTesla, leaned her head on her hand while her elbow was on the center console. It may have appeared that she was holding a phone up to her head.
That’s definitely an interesting little undocumented change, and we’re glad to see that Tesla is working to improve user safety for FSD (Supervised).
Tesla recently launched software update 2025.8.3, which included a bunch of “minor updates.” Nestled away in the release notes are a couple of interesting features - including some major changes to the Energy App.
We’re not quite sure we’d call these minor updates, so let’s take a bit of an exploration of the revitalized Energy App.
The Energy App has received some new categorization features in the Consumption tab. You can once again limit the graph by distance. As part of the 2024 Holiday Update, Tesla redesigned the consumption tab and brought it to the new Model S and Model X for the first time. However, with the redesign, Tesla removed the ability to choose the distance shown in the graph, instead providing a static display of the last 200 miles (300km).
The first part of the improved Energy App is bringing back this distance filter. You can now choose between showing the last 10, 100, or 200 miles (15, 150, or 300 km). This differs from the previous available distances of 5, 15 and 30 miles, but brings back the ability for the driver to choose a distance that may be more applicable to how they’re driving.
We’d love for Tesla to introduce custom distances by pinching and zooming the graph or simply add the ability to choose “This Drive Only” to the list of available distances.
Reset Energy App History

Sadly, the “Instant Range” button that was available in the Energy App before is still not available, but Tesla introduced a new feature that may be even better. You can now clear your driving history so that the graph only reflects your current driving style.
This is a little hidden, but if you tap the little info icon at the top near your average Wh/mi, you’ll now be presented with a dialog that lets you clear your history.
This could be useful if you’ve just come from some hard driving on a track or off-road, where energy consumption could be exaggerated. It could also be useful if you just started towing or a different type of driving that is drastically different from your current driving.
Other Changes
In addition, it looks like future predictions of the Energy app now take into account your driving history and apply that in addition to expected vehicle consumption, weather, altitude, and the multitude of other factors that your Tesla constantly takes into account while calculating your expected range.
While these are smaller improvements to the Energy app, they added some important functionality, as it helps users better understand their vehicle consumption and display data that is more applicable to the current driving style.
This is a great example of Tesla listening to its customers and bringing back features they had previously been removed. Check out the video below by akide on the updated Energy app in update 2025.8.3.
Sandy Munro once again had the opportunity to chat (video below) with Lars Moravy, Tesla’s Vice President of Vehicle Engineering, as well as Franz Von Holzhausen, Tesla’s Chief of Vehicle Design. This time, rather than focusing on the improvements to the refreshed Model Y and all the new engineering behind it, the focus was on Tesla’s autonomous ambitions.
In this case, the Cybercab and Robovan were the key highlights, with a distinct focus on the Cybercab. With that all said, let’s dig into all the fun new stuff. You can check out the entire video at the end of the article.
Cybercab Unboxed Process
The Cybercab will be the first of Tesla’s vehicles to use their new unboxed assembly process, which builds vehicles in parallel sections, and then brings them together all at once for final assembly. Traditionally, vehicles are assembled from the ground up, and sometimes even disassembled for parts of production to take place.
This innovative method involves using a big rear and front casting, brought together by a structural battery pack on the floor. The door rings are hot-stamped and laser-welded to form the side shell of the Cybercab, resulting in a very rigid structure that can also absorb crash impacts due to its unique manufacturing.
Paint-Free Panels
We’ve already talked about the Cybercab’s unique paint-free panels, but we’ve never heard until now exactly how Tesla intends to manufacture them. Tesla will inject colored PU plastic onto the backside of another plastic part (formed from various processes) and then ultrasonically weld that entire piece to an inner part.
That essentially combines multiple parts into one smooth piece that is easy to repair - because all you have to do is remove the entire panel - it just comes off as the interior fasteners are removed. There is no subframe holding it together - instead, the subframe is part of the panel.
The only area of the vehicle that will have any paint will be the hot-stamped door rings - which will be painted to improve corrosion resistance to protect the steel.
Aerodynamics
Aerodynamically, the Cybercab boasts the largest aero-cover-to-wheel ratio of any Tesla vehicle. This updated aero cover improves efficiency, even with the Cybercab’s relatively large tires—chosen to reduce rolling resistance. Interestingly, the impact of unsprung weight on efficiency is minimal compared to the benefits of improved rolling resistance and aerodynamics.
Another key to the aerodynamics is the teardrop shape of the Cybercab itself. With its low profile and smooth shape, it is extremely aerodynamically efficient. While neither Sandy nor Lars delved into drag coefficients, we expect it will likely be more efficient than the Model 3’s already fantastic Cd of 0.219.
Range and Battery Pack
Tesla currently has prototypes undergoing real-world testing at Giga Texas to evaluate range and efficiency. The goal is to ensure the vehicle can operate throughout an entire day in the city before returning to charge.
Tesla is targeting a battery pack under 50kWh, delivering close to 300 miles of real-world range—an impressive efficiency of around 166Wh/mi, even outperforming the Model 3’s lowest at 181Wh/mi.
When Does It Arrive?
So, with all that new knowledge - when does the Cybercab arrive? Well - the prototypes for the June Robotaxi network deployment in Austin are getting prepared now - but Tesla expects to begin production and sales sometime in the first half of 2026.
