Tesla software update 2021.40 to add 'Live Camera Streaming'

Tesla is on a roll with it's app lately. We've seen numerous releases since the app was updated to version 4.0 back in August. Just yesterday Tesla released version 4.2.0 with quick action buttons in one of its widgets and much better interior details of the vehicle.

With this same release, it looks like Tesla is starting to prepare to release a much anticipated feature in the near future, the ability to stream live video from your car.

Live Stream Video From Car

With the release of software update 2021.40, Tesla will allow you to stream live camera feeds from your car directly to your phone. You'll be able to view any of the cameras that are included in Dashcam or Sentry Mode, which include the front and rear cameras and the two side fender cameras.

When viewing the live feed from your car, you'll also be given the chance to save the video directly to the car. It's possible that Tesla will allow you to save it to your phone, but judging by the fact that Tesla is requiring your car to have a USB drive in order to stream video and that there is a new API endpoint to save dashcam footage, it's likely that the recorded video will be saved to your car instead of your phone.

View Sentry Clips and Dashcam Footage

In addition to being able to view live video from your car, and notably more useful. You'll now be able to remotely view Sentry Mode clips instead of having to wait until you get back to your car.

You'll likely be presented from a similar interface that appears in your car to view Sentry Mode and Dashcam clips and you'll be able to view and delete them.

Requirements

There will be a few requirements before you're allowed to stream video to your phone. Your car will obviously need to have the ability to use the Dashcam and Sentry Mode features, which require a vehicle with FSD HW 2.5 or higher. It will also require your vehicle to have software update 2021.40 or higher.

In addition, before being able to initialize the video stream, Tesla will require that your car be in park, have all doors closed and for no one to be in the car. Tesla is making these requirements presumably for privacy concerns around spying on individuals in a private environment.

Premium Connectivity Required

It's strongly suspected that your vehicle will need to be subscribed to Tesla's Premium Connectivity or be connected to WiFi in order to stream live video or remotely view Dashcam or Sentry Mode videos.

Tesla will very likely not introduce a higher priced connectivity option. Tesla already allows you to stream video services for unlimited periods. The bandwidth required to stream your car's cameras will be fairly small when compared to streaming video.

Limitations / Daily Limit

Tesla will impose a daily viewing limit on how long you can remotely monitor your vehicle with video. This is likely to prevent users from live streaming video for long periods of time. For example, if they went out to dinner, started a live stream and set their phone down.

I suspect the daily limit will be more than reasonable and you'll be unlikely to reach the limit unless you're trying to use your car as a security camera.

Talk to Car From Your Phone

When monitoring your car remotely, you'll be able to talk directly to your phone and have your voice come out of the car. This will require your vehicle to be equipped with the Pedestrian Warning System (PWS). Basically, if you have the Boombox feature, then you have the PWS.

In addition to being able to talk to the car from your phone, you'll also be able to honk the horn and flash your car's lights to alert anyone around your vehicle.

This snippet was found in the latest Tesla app:

"Tesla allows you to use your microphone to speak through your car or attach videos when scheduling service for your vehicle",

If you don't, then for some models Tesla can retrofit the PWS for a couple hundred dollars, although it's not available on all model years. Your car will need to already be wired to support the outdoor speaker.

I can see this feature being fun, but also useful. If there's someone seriously looking at your vehicle with ill intent, then what better way to deter them then to talk to them. They'll likely think that you're walking up to the car and walk away.

Of course, I'm sure there will be lots of humorous ways owners will use this feature as well.

Unfortunately, because Teslas do not (yet) have external microphones, this will be one-way audio. So you'll be able to talk to the individuals, but unfortunately unable to hear their surprised or funny reactions.

In-Car Purchases

As we talked about back in August, Tesla is adding in-car purchases. Features that you can buy directly on your phone today will become available in the vehicle as well. Features such as adding the FSD subscription, Performance Boost and others will now be only a couple taps away.

According to information in the latest iOS app, this feature will also be added in the 2021.40 software update.

As the owner of the vehilce, you'll see be able to limit in-car purchases as well, much like you can limit in-app purchases on other platforms.

Software updates have contained slightly less than usual lately as Tesla focuses on FSD and catching up on the new Model S software, but 2021.40 is surely to be an exciting release, even if this was the only feature in it.

Stay tuned for more.

Tesla Updates Energy App in Update 2025.8.3: Adds Reset and Distance Filter [VIDEO]

@EV3_Model3 on X

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.

Select Distance in 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

@EV3_Model3 on X

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.

Franz and Lars Discuss the Tesla Cybercab in New Interview

Munro Live

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.
