While Tesla showed off a fantastic list of upcoming features for the 2024 Holiday Update, several things were left out. Now that the update has started rolling out in small numbers to the public, it’s our chance to find out about some of these smaller features and view others in action for the first time.
The Energy app has been updated for all models. For the first time, the Model S, Model X, and Cybertruck receive the Consumption tab, which shows real-time energy usage and how the car performed over a certain period. Previously, only the Drive and Park tabs were available.
The consumption tab was already available on the Model 3 and Model Y, but it’s receiving some changes. The Y-axis (energy used/gained) now appears to adjust based on the data; however, the X-axis (distance) is now fixed at 200 miles or 300 km, and the user can no longer change it. Previously, you could switch the graph between a 5-, 10-, and 15-mile history, but now it appears to be static at 200 miles.
The Energy app also included buttons to view your average range over the selected distance or your real-time range. However, those buttons have been removed, and you can now only view your average range at the top of the app and see how it compares to the rated (EPA) range. You can also view your projected range (the distance you can travel at this rate), which shows up in the middle of the graph.
In addition to those metrics, the app also shows you the total amount of energy used in the bottom left corner, which is a nice addition.
The addition of the consumption tab to the Model S, X, and Cybertruck is great, but some users may not be fans of the simplified look and controls. Not being able to select the distance or see the instant energy usage is a little bit of a disappointment. We would’ve loved to see the ability to pinch in and out of the graph so that you can adjust the time period to practically anything you wanted, up to a maximum of the last 200 miles, but overall these are nice improvements.
Unfortunately, this does not bring the Energy app to legacy Model S and Model X vehicles.
Weather At Destination
As part of the Holiday Update, Tesla is including a new feature to show the weather at your arrival destination. Tesla added the ability to view live weather and weather forecasts in the 2024.26 update, and now they’re extending it so that you can also view the weather at your destination.
The UI is intuitive, and tabs are simply added so that you can switch between the weather at your current location and your destination.
Tesla will also highlight any significant weather differences between your current location and final destination.
This feature is available for the Model 3, Model Y, Cybertruck, and new Model S and Model X. It also includes Intel-based vehicles (MCU 2), but like the original weather feature, it requires Premium Connectivity.
Another big part of the Holiday Update is precipitation maps appearing as overlays on your vehicle map. When you tap the new precipitation icon on the right next to the satellite imagery button, a precipitation map overlay will appear, giving you insight into areas with incoming rain or snow. There is also an animated 3-hour forecast that shows weather patterns.
This particular portion of the Weather update requires an AMD (MCU 3) vehicle. Unfortunately, since Tesla is paying for this weather data, it’s only available if you have Premium Connectivity and using a hotspot or being on WiFi is not enough to enable the feature.
It’s available on all vehicles except the legacy Model S and Model X.
Boomerang Fu
@g3st4l1
The new Boomerang Fu game will let you slice and dice your friends in a frantic physics party game. The game is available in Arcade > Boomerang Fu, and must be downloaded before being played. If you have Premium Connectivity, you’ll be able to download it on the go.
This new game requires an AMD Ryzen-based (MCU 3) vehicle and it’s available on the new Model S, new Model X, Model 3, Model Y and Cybertruck.
Light Show Improvements
Tesla has really hit it out of the park with Light Show Improvements in the 2024 Holiday Update. The biggest change is the ability to start Light Shows directly from your mobile app (V4.39.5+), but there’s more. Tesla has added two new built-in Light Shows based on Cyber Symphony by Lionel Yu and Ready for Assault by Evgeny Bardyuzha.
Tesla is already adding the ability to control interior lighting for Light Shows by adding special color effects, which is sure to make Light Shows even more spectacular. Tesla has also extended the maximum allowed length of a Light Show with this update.
You can check out the music for Ready for Assault below.
Theater Updates
Theatre mode can now be interacted with via the rear screen on vehicles that have them, including the ability to edit playlists or play and pause videos.
But here’s the most surprising feature in the update. You’ll also be able to start a video in the web browser before you start driving and it’ll continue to play when you shift into drive only. The video will be disabled, but the audio will continue to play. So you’ll now be able to listen to YouTube-only podcasts.
Tesla is also giving us the ability to control the video with the media player, so you’ll be able to pause or start the content while driving.
Dashcam Viewer & Sentry Mode Improvements
@g3st4l1
The Holiday update is packed with features, but one of the most useful will be the ability to view your dashcam and Sentry Mode videos directly from your phone.
You’ll be able to access all of the content on your USB drive from your phone. The vehicle will stream the video from your USB drive, so the vehicle will need an active WiFi or cellular connection in order for the feature to work.
You’ll be able to change cameras, jump to Sentry Mode alerts, and even save clips onto your phone, making it much easier to save that important data.
Sentry Mode Improvements
Sentry Mode also received a batch of improvements. Tesla already sends mobile notifications for critical events - like an alarm going off. Now, Tesla will notify you if Sentry Mode is active and a door handle is pulled on a Model 3 or Model Y. In addition, if someone attempts to open the trunk by pressing the button - or open the Cybertruck’s vault - you’ll get a notification for that too.
The update is currently only going out to vehicles that don’t have access to FSD. However, we expect it to soon be available to users on FSD 12.5.4 and later available to those on FSD 12.5.6 and FSD v13.2.
If you’ve noticed any undocumented features in this update, definitely let us know through the Contact Us link at the bottom of this page.
Tesla’s Dan W Priestley attended the Advanced Clean Transportation (ACT) Expo in Anaheim, California, and provided an update on Tesla’s Semi truck program. The presentation covered several key developments on the status of Tesla’s Nevada Semi Factory, refinements to the Semi, and Tesla’s plans for charging and ramping production through 2026.
Let’s dig in and take a look at everything that was captured by the Out of Spec team at ACT Expo. The original video is embedded below if you’d like to watch it.
Semi Factory & Production Ramp
Priestley reaffirmed the timelines mentioned during Tesla’s Q4 2024 Earnings Call that Tesla will scale Semi production in 2026. To achieve this, Tesla has been actively building and expanding the Gigafactory Nevada site, specifically to support the production of the Tesla Semi. The dedicated Semi facility will have a targeted annual capacity of 50,000 Semi trucks.
Following the beginning of production, Tesla will utilize the initial trucks to integrate into its own logistics operations. This will serve as both a final real-world testing ground as well as an opportunity for Tesla to gather data internally. Tesla plans to begin subsequent customer deliveries throughout 2026 as the ramp-up continues.
Reuters also reported that Tesla is hiring over 1,000 new employees at the Semi Factory to begin the rapid ramping of the program.
Semi has already amassed 7.9 million miles with Tesla’s current testing and operational fleets, providing some real-world data and testing. Feedback for the truck has been exceptionally successful, with many drivers praising the Semi’s performance and comfort.
New Tesla Semi Features
Of course, it wouldn’t be a Tesla keynote without showing off some new things. The Semi will be available in 500-mile and 300-mile range configurations, now featuring updated mirror designs and a drop-down glass section to improve visibility and allow easier interaction with external elements—such as control panels at ports, for example.
New Electric Power Take-Off (e-PTO)
The Tesla Semi will also feature a new capability called Electric Power Take-Off, or e-PTO system. Similar to the PTO systems found on other vehicles, this will allow the Semi’s high-voltage battery to power auxiliary equipment at variable voltages. That includes being able to power things like climate-controlled reefer trailers, potentially replacing the noisy and polluting diesel generators traditionally used for this purpose.
Charging and Batteries

Tesla is also working on an updated battery pack design for the final production design of the Semi. This new pack is designed to be more cost-effective to manufacture. The battery pack itself is slightly smaller than before, but the truck maintains the same level of range through efficiencies. Dan also confirmed during his keynote that the battery cells for the Semi will be sourced domestically inside the United States, helping to alleviate potential burdens due to tariffs.
On the charging front, Tesla is using MCS - the Megawatt Charging System - capable of 1.2MW - and designed specifically for Semi. The system uses the same V4 charging hardware found at Supercharger sites but focuses on that larger power output. Alongside a smaller physical footprint, Tesla will be able to configure these V4 cabinets for either dedicated Semi charging or for shared power scenarios with regular Superchargers. Tesla is also working on an integrated overnight charging product, but Tesla isn’t ready to talk about it yet.
46 Semi Charger Sites Coming
The 46 new MCS sites coming soon.

Finally, Tesla has made substantial investments in a public charging network for the Semi. There are currently 46 sites in progress throughout the United States, and plans for significant expansion throughout 2026 and 2027. These sites are strategically located alongside major truck routes and within industrial areas to support long-haul and regional operations. Tesla is aiming to offer the lowest possible energy costs to operators to help incentivize adoption.
This was one of the best updates to the Tesla Semi we’ve received since its initial unveiling. It seems that the Semi will receive a big portion of Tesla’s attention in 2026, while Robotaxi and FSD Unsupervised take the stage this year.
The Tesla Semi has the potential to transform transportation even more dramatically than EVs already have, serving as a testament to Tesla’s mission to electrify the world.
Sentry Mode is an invaluable tool for owners - capable of keeping the vehicle safe and secure even when you’re not around. This is especially true in recent times, with the misguided and unfortunate incidents surrounding Tesla ownership, including damage to Tesla vehicles, showrooms, and Superchargers.
B-pillar Camera Recording and Dashcam Viewer
With the 2025 Spring Update on 2025.14, Tesla is expanding Sentry Mode’s functionality for certain vehicles with some much-needed changes. Sentry Mode and Dashcam can now record footage from the vehicle’s B-pillar cameras. These cameras are located on the side pillars of the vehicle, between the front and rear doors.
This adds two crucially needed viewpoints, making Tesla’s Sentry Mode a truly 360-degree security system. These cameras also provide the best angles for capturing license plates when parked, so they will be greatly appreciated by owners in the event of an incident.
These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view. It also allows users to jump back or forward in the video in 15-second increments.
However, to the disappointment of many owners, not all vehicles are receiving these updates due to the additional processing power needed.
Limited to Hardware 4 Vehicles, Ryzen Isn’t Enough
We have confirmed that Tesla is only adding the additional camera recording and improved Dashcam Viewer on hardware 4 (HW4 / AI4) vehicles. The newer hardware presumably has the additional processing power and bandwidth needed to handle recording and saving the two additional video streams during Sentry Mode and Dashcam.
For the time being, owners of HW3 vehicles are not receiving this feature. This includes all vehicles with HW3, even those with AMD Ryzen infotainment systems. If you’re not sure whether your vehicle has HW3 or HW4, you can refer to our FSD hardware guide.
While there’s no doubt that recording two additional camera streams would be more computationally intensive, we hope that Tesla adds the improved Dashcam Viewer to HW3 vehicles in a future update.
Cybertruck Also Missing Improved Sentry Mode
Surprisingly, and most confusing for many - is the fact that the Cybertruck is also not receiving the improved Dashcam Viewer and B-pillar camera recording with this update. This struck us as odd, especially since the Cybertruck is currently the only vehicle with the improved, more efficient version of Sentry Mode.
Every Cybertruck is equipped with HW4 and AMD Ryzen infotainment units, so this clearly isn’t a hardware restriction. It’s possible the more efficient Sentry Mode is playing a role here due to the infrastructure changes. However, we expect Tesla to address this in a future update and eventually release these features for the Cybertruck as well.
Given the Cybertruck’s high visibility and its status as a frequent target for both positive and negative attention, many owners hoped that the Cybertruck would be one of the vehicles to receive this feature.
Adaptive Headlights
Tesla finally started rolling out its adaptive headlights in North America. While the new Model Y already came with the feature when it was released last month, other vehicles with matrix headlights are now receiving the feature in the Spring Update.
All vehicles with matrix headlights are receiving this feature, which includes the new and old Model 3, first-gen Model Y, and the new Model S and Model X.
If you’re not sure if your vehicle includes matrix headlights, check out our guide. What’s interesting here is that older vehicles that were retrofitted with matrix headlights due to an accident or user replacement are also receiving the adaptive headlights feature.
Legacy Model S & Model X
As with most updates, the older legacy Model S and Model X are not receiving all the features included in this update. Unfortunately, some of the features, which include the Blind Spot Camera on the instrument cluster, Save Trunk Height Based on Location and Keep Accessory Power On are limited to the new Model S and X.
Legacy S and X models will receive the Alternative Trip Plans feature, Avoid Highways (Requires Intel MCU) and the Keyboard Languages feature.
These vehicles are also receiving all the features in the Minor Updates section except for the visualization showing how far the door is opened, which is exclusive to the Cybertruck. These additions include improved music search results, contact photos in the phone app, automatic connecting to hotspots, the ability to show third-party chargers, view Supercharger amenities, and various improvements to music services.
While many users will be disappointed not to receive the B-pillar camera recording and Dashcam Viewer improvements, it’s important to remember that Tesla typically does a great job at bringing features to older vehicles, at least with the Model 3 and Model Y. If a feature isn’t added, it’s usually due to a hardware limitation.
