Tesla is finally getting ready to release support for the Apple Watch and presumably Android wear devices. It’s anyone’s guess if development for smartwatches has been in the works or if the Tesla team found out at the same time as the rest of us. Despite this request being made several times before, Elon Musk recently responded to the request with a simple “Sure.” Although the response is short, Musk has a good record of delivering on items he has said “sure” or “okay” to on X/Twitter. A few examples are agreeing to add WiFi garage door support, a glovebox PIN feature, disabling mirror auto-dimming, and many others. When Musk responds to these requests, in all likelihood, they’re already on Tesla’s product roadmap.
The days of living in fear of your phone running out of juice and not having your key card may be numbered. X user @dani_elle831 described that exact situation: “well it finally happened. my phone died & I got locked out of my tesla thankfully the massage place let me use their phone & hubby unlocked it from his phone not sure why the car can’t be unlocked using an Apple Watch or other smart watch. any chance this could be incorporated @elonmusk?”
One of the big advantages Apple Watch and Android Wear support could bring is the ability to use your watch as a vehicle key. From the context of the post on X, it’s not clear whether this will be included, as the post simply talks about unlocking the vehicle when you don’t have a working phone on you. It could mean having full-fledge key support on your watch, or simply being able to unlock and start the vehicle over the internet like you can already do through the app when you’re outside of Bluetooth range.
There’s no doubt that having ‘phone key’ support would be the best option, as it would work seamlessly and not require an internet connection, although it’s not clear what Tesla’s intentions are. Tesla has not added support for Apple’s CarKey and is unlikely to add it at this point. However, Tesla could add phone key support in the same method they already support on iPhones and Android devices.
Phone key leverages Bluetooth to unlock the vehicle when it’s nearby, and Tesla recently added ultra-wideband support, which brings even more precision to phone key. However, ultra-wideband is only available on newer devices, such as the iPhone 11 and later, some Samsung Galaxy 21 devices and later, as well as select other models. It also required a new Model 3, Cybertruck, or a newer Model S or X, with these sensors built in. Unfortunately, the previous generation Model 3 and the current Model Y do not include ultra-wideband support.
It is interesting to note that the Apple Watch has had ultra-wideband support since the Series 6, including the new Ultra models. Hopefully, we’ll be in for a treat and will see full phone key support through Bluetooth and Ultra-wideband, but either way, it seems like we’ll at long last be able to unlock the vehicle from our smartwatches in some form.
From Widgets to Watch Support
Tesla added lock screen widgets to the iPhone back in 2022
Not a Tesla App
Tesla rolled out lock screen widget support on iPhones in app update 4.14, and we’re likely going to see these same lock screen widgets supported on the Apple Watch and possibly on Android Wear devices. Tesla has two lock screen widgets that display relevant vehicle information. The larger one displays the range left on the vehicle, the name of the vehicle and a progress bar showing the charge level. If you have more than one Tesla, you’ll need to choose which vehicle is displayed in the widget, however, you can have multiple instances of the same widget. There is also a smaller widget that is half the size and simply displays the vehicle’s state of charge. Both of these would adapt well to ‘complications’ on the Apple Watch..
Smartwatch Support Expectation
Another concept of a Tesla app on the Apple Watch by @niccruzpatane
@niccruzpatane
We don’t know what Tesla is developing and it could be anything from a full-fledged Tesla app for smartwatches that allows you to access most commands available in the Tesla app such as charging, unlocking, starting the climate, setting charge level (as shown in the concept above), and even include full phone key support. However, it could also be a slimmed-down app that introduces watch widgets and allows you to access the most important commands and information about the vehicle, such as seeing the vehicle’s range, unlocking it, and starting a charge. Smartwatch support has been a long time coming, and even if Tesla releases the latter, it will be a great addition.
Other Manufacturers
Tesla's development of smartwatch apps is a welcome step, but surprisingly a step behind the competition, which is unlike Tesla in terms of software. Companies like Porsche, BMW, Dodge, Toyota, and Ford have already introduced support for smartwatches. These apps offer a range of features such as remote engine start and stop, door lock and unlock, car finder, vehicle status, and parking meter assistance.
Timing is Everything
Tesla's consideration of a smartwatch app comes at an intriguing time, closely following Apple's announcement to cancel its electric vehicle project, which would’ve competed directly with Tesla. It’s likely a coincidence, and it could have more to do with the recent addition of ultra-wideband, as this new tech provides significant improvements in energy usage and precision. We should find out more soon, so stay tuned.

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

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.
