The Features in Tesla's 2024.38 Software Update

Not a Tesla App

Tesla has released software update 2024.38 to its employees for its last round of internal testing. We now have preliminary release notes for this update.

It looks like this update will be smaller and focus on two main changes. However, keep in mind that there could be additional features that may only apply to certain regions or vehicles that are not mentioned here.

The two features are the ability to use Spotify with a free Spotify account (still requiring Premium Connectivity), and improvements to the vehicle’s side mirror functions.

We’ve recently been able to confirm these changes with an employee.

Spotify

Since Premium Connectivity’s free Spotify Premium (for Europeans only) is going the way of the dodo, it looks like Tesla and Spotify will now allow you to log in to your Spotify account with a free account, at least in Europe and Australia. Tesla also recently announced that vehicles in North America that use the “Streaming” app will now be changed to a free version of Slacker that will include ads and other limitations.

If the ability to use Spotify for free is limited to Europe and Australia, where these users already had free access to Spotify Premium, then this isn’t a huge deal. However, if Tesla and Spotify now allow you to stream Spotify in your vehicle with a free account, that will be a huge win for many owners. The free version of Spotify has limited skips and includes ads. Other music services require you to have a premium or paid subscription before allowing you to stream in the vehicle. In either case, you’ll still need Tesla’s Premium Connectivity plan to stream music over the vehicle’s connection, or you could use your phone’s hotspot feature.

Side Mirrors

The side mirrors are finally getting some additional customization options with two improvements.

First, you will now be able to customize the side mirror’s tilt when reversing. By default, a Tesla’s side mirrors will angle downwards while reversing to provide a better perspective of what’s close to the edges of your vehicle, rather than your blind spots. You’ll now be able to customize the level of tilt when this happens. To adjust the tilt angle, go to Controls > Mirrors > Adjust Tilt Position.

This will help folks who are either taller or shorter than the norm – you’ll now be able to customize the angles to better suit you. It’s a simple update, but a much-appreciated one!

Next up for the side mirrors – you’ll be able to fold them in the quick menu. That’s the menu that pops up when you press and hold down the left scroll wheel. You’ll also be able to unfold them from the quick menu as well.

Other Updates

Similar to other recent updates, Tesla now has an Other Updates section where they list smaller features that don’t warrant their own release notes.

In this section, Tesla outlines four improvements, although only two are noteworthy. One of them is the ability to manually fold the side mirrors using the quick function that we talked about above and the other is improvements to the WiFi menu. The four points Tesla mentions in their release notes are:

- The Wi-Fi menu provides more information about your Wi-Fi connection as well as tips for improving your connection.

- Hold down the left scroll wheel and select Fold Mirrors to fold the mirrors in or out.

- This update contains important security fixes and improvements

- This version contains minor fixes and improvements

Release Date

This update is expected to start rolling out to users in the next week or two, so it won’t take long now before we have the full release notes for this update available.

A Closer Look at Tesla's Updated Energy App - What's Changed

Not a Tesla App

One of the big undocumented changes in Tesla’s 2024 Holiday Update was the changes to the Energy app. While the Model S, Model X, and Cybertruck received the Consumption tab in the Energy app for the first time, the changes made for those models also carried over to Model 3 and Model Y.

The Consumption tab lets you view your vehicle’s consumption over recent trips as well as view projected range estimates based on historical usage, but it now offers different options.

Sadly, legacy Model S and Model X vehicles produced before the 2021 refresh still don’t have access to the Energy app at this time.

Energy App

Tesla’s Energy App previously let you view a lot of in-vehicle data on what is consuming energy and how to improve your energy consumption. It was previously refreshed in 2022 and brought Drive, Park, and Consumption tabs to help compare actual vehicle energy consumption versus what you’d expect from the EPA ratings.

The old Energy App's consumption page.

Key Changes

The Energy App has seen a lot of changes - mostly in the name of simplicity and reducing confusion. Some changes reduce functionality, but others bring even more. All of these changes impact the Consumption tab - the Park and Drive sections are unchanged.

Distance

Previously, you were able to switch the graph on the Consumption tab to show the last 5, 15, or 30 miles. Instead, it is now a static display of the last 200 miles (or 300km). This means your last 200 miles of driving - whether it's a single trip or multiple trips. Your range prediction and energy usage are now based on 200 miles of driving instead of the previous selectable distance.

This allows for a more reasonable range prediction as small bursts of high-energy usage, such as time spent accelerating to highway speeds from an offramp, are now less of an impact and are instead averaged out by regular driving.

However, for those who love to take their Teslas to the track or tow regularly, this makes the consumption significantly less useful because you can no longer see your actual energy usage for the type of driving you’re doing. This could be fixed with a reset button or by adding the ability to select your distance — similar to before.

Projected Range and Average Wh/mi

Unfortunatley, the Instant Range button has been removed, and the graph is now locked on what was previously the Average Range. Essentially, you cannot view your real-time range based on current instantaneous consumption - but you can view the overall projected range.

Additionally, average Wh/mi and projected range are still displayed - but in different areas compared to before. The projected range is displayed on the center-left side of the graph, while the average Wh/mi is now displayed at the top of the screen.

Not a Tesla App

Compare Vs EPA

Another new feature is that the average range is now compared to the EPA estimated range in terms of wh/mi. You’ll be able to see whether your driving style and conditions put you over or under the EPA estimate in a pretty quick way, which is helpful.

This new comparison is located just under your average Wh/mi.

Small and minor adjustments to your driving style - like not taking off like an electric lightning bolt at every red light - will make a big difference to your range. Don’t worry - we know its hard, we love doing it too! Other things - such as driving downhill versus uphill, will have an impact that you can’t necessarily avoid unless you’re old enough that you went to school uphill both ways.

Total Vehicle Consumption

The final new feature is a total vehicle consumption number at the bottom left, under the chart. It will tell you how much energy you’ve consumed over the distance you’ve driven so far. This is a convenient way of seeing exactly how much energy you’ve used.

Bug

There’s currently a bug in the way the Y-axis is labeled. The yellow area of the graph means the vehicle is using energy, while green means the vehicle is generating energy through regenerative braking. However, the Y-axis is currently mislabeled and shows generated energy as using about 100-200 Wh/mi.

The confusion appears to be due to the dark gray line, which looks like “0” on the Y-axis but actually represents the vehicle’s rated range. We would expect this to be Y-axis 0, since above the line the graph is yellow, and underneath it, the graph is green. However, this line is at about the 240 Wh/mi mark but will vary depending on the vehicle.

Due to this bug, it’s currently not possible to see how much energy is being generated.

Dynamic Y-Axis

The Y-axis in the Consumption tab is now dynamic - it will expand and contract automatically based on the driving data. We’ve seen it go from 400 Wh/mi all the way up to 800 Wh/mi. You likely need to be in a Model S Plaid or Cyberbeast with Launch Mode to see numbers much higher than that.

We’re sad to see the X-axis get locked to 200 miles, but being able to see total vehicle consumption and comparing average consumption against what’s rated is equally, if not even more valuable.

Overall, the new and improved Consumption tab is simpler and doesn’t require user input. While it takes away some features, it makes it easier for drivers who may not use it regularly. The most important piece is the projected range, which is now easier to see and understand unless you're towing and need the historical usage erased because it’s now irrelevant to your current drive. Hopefully, Tesla will allow you to scrub the graph horizontally in the future, adding the ability for the user to adjust the X-axis dynamically.

Tesla Smart Voice Assistant Coming - Vehicle Responds for First Time

Not a Tesla App

If you hop into your Tesla and say ‘Hi’ or ‘Hello’ after pressing the Voice Command button, there is a good chance it’ll reply with “Hello!” This is the newest and most interesting piece of news pointing us to the conclusion that a Tesla voice assistant is on the way.

Previously, if you tried this, it would simply return “Command not understood.” This is the first time the vehicle is responding and interacting with the user.

Experience It Yourself

You’ll need to have your vehicle language set to English. Once that’s done, you can use the voice command button on your steering wheel or yoke - for the Model 3 and Model Y, push the right wheel button, and for the Model S, Model X, and Cybertruck, press the button. Then go ahead and say Hi or Hello.

The Hello! response may even have regional differences. For a German Tesla owner, after setting his language to English, the response came back as “Hallo.” We’re interested to see what the responses may be in other regions, so let us know if you notice anything interesting.

We’ve tried a few other basic things, but it seems that, for now, the vehicle only replies to a simple greeting. Asking it what time it is or the $TSLA stock price doesn’t seem to do much yet - unless you’re in China with the updated Smart Assistant.

Not a Tesla App

Server-Side Update

This update appears to be happening over Tesla’s voice system backend and doesn’t require the Holiday Update. Users who aren’t on the Holiday Update are reporting that they’re getting this new response as well.

We already know that Tesla interprets speech remotely, and the driver’s voice is not processed in the vehicle. Instead, the voice snippet is transmitted to Tesla’s servers, where Tesla processes it and sends a response back to the vehicle so that the vehicle can interpret it. This is unlikely to change with a smart assistant, as Elon Musk has already said that Grok will still process data server-side instead of on-device.

Many users recently also noticed significant improvements to voice commands, saying that the system understands them better and that responses now come back faster.

All of these things point to a new backend system for voice processing that Tesla is testing. It’s not unusual for a company to switch to a new backend process but keep the capabilities the same as the legacy system until it’s ready to roll out the new features. At that point, it’s simply a flip of a switch to allow the new capabilities.

The new smart assistant that was rolled out in China is mostly a backend change, with the in-vehicle experience largely remaining the same. The activation method (button press) and user interface remain the same. What changed is the response that comes back from the server, and the assistant gained a voice. The new voice we receive with a smart assistant could very well be the new voice users are experiencing in the navigation system in newer vehicles.

Below is a video of the voice assistant in China:

Vehicle Support - Intel?

When China received the Smart Assistant, it was locked to cars equipped with AMD Ryzen processors only. Shortly after its initial launch, it became available to older cars with Intel Atom processors as well.

However, we’re not sure whether it would apply to legacy Model S and Model X owners. A legacy vehicle owner had their vehicle report “Command not understood” when they tried the ’Hi’ voice command.

Grok for Tesla

Elon has previously mentioned that Tesla vehicles would receive Grok AI. Grok, as of yet, still doesn’t have live speech support like other LLM models such as OpenAI’s ChatGPT or Google’s Gemini. However, a major update to Grok just brought massively improved image generation via a new model called Aurora.

xAI has been hard at work improving Grok, and we’re sure that live speech support is on its way soon. Once that feature arrives on X, Tesla will likely be well-positioned to enable a Grok-powered smart assistant fleet-wide with a flick of a switch.
