Exclusive: Tesla's Model 3, Project Highland Exposed: What’s Changing

Tesla's Model 3 is going to go through some of its biggest changes this year

Tesla

Tesla has been working on a revamp of one of its most popular vehicles, the Model 3. The project is codenamed Project Highland and the vehicle will see the most profound changes since it launched in 2017.

Despite Tesla keeping the car under wraps for months, we now have early information on the major changes coming to the best-selling electric vehicle of all time. Thanks to a trusted insider, we can confirm and provide more information about Tesla's plans for the car. Inside and out, the Highland will change.

Redesigned Headlights

Caped Model 3s have been spotted with the front bumper, rear end and dash covered. However, more recently the incognito Model 3 also had its headlights covered. The headlight openings that were clear before were now covered in what appeared to be duct tape. Turns out there is a good reason for this. The Model 3 revamp will include redesigned headlights. The new headlights will be a different shape than they are today. Tesla has been providing some models with matrix headlights, but they have yet to be enabled through software yet. Tesla will continue to offer matrix headlights through this redesign, although it's not clear whether they'll be enabled at launch either.

Bumper Camera

A new shape of headlights also means a new front bumper. There has been a lot of speculation that the front of the car is changing after recent images show a smoother front end. Tesla is always looking for more aerodynamics to improve the drag coefficient. However, there's another good reason for redesigning a new front bumper. The front bumper will now house a single camera in the center area of the lower-vent area of the bumper.

The location of the new camera will be very similar to the one shown off on the Cybertruck at Tesla's Investor Day.

Since the company removed USS, people have been wondering how the car will detect objects in what's considered a camera blind spot directly in front of the vehicle. Now we know.

Rear Bumper

The rear bumper of the vehicle is also being redesigned, although it's not clear why. We don't expect the rear camera to change position and there won't be additional cameras in the rear of the vehicle. The new rear bumper could just be to 'refresh' the car or may have cost-saving measures.

Mirrors

Updated mirrors are also joining the party. We're told that they will receive a very minor 'refresh' and will look very similar to the way they do today. It's not clear whether Tesla is changing them to match other areas of the vehicle better or to streamline manufacturing, but we've been told to expect a minor change.

Additional Cameras

Tesla recently launched hardware 4.0 on Model S and Model X cars, although many were surprised to learn that the new vehicles feature the same number of cameras as HW 3 vehicles, when hardware 4 allows for more cameras. This is where Project Highland comes in.

We can now say that more cameras will indeed be used in Project Highland. There will be three new cameras in all, one in the center of the front bumper as we discussed earlier, and two more on the sides of the vehicle.

The fender camera housing will now contain two cameras each. One will face backward as it does now, while the other will point in the other direction. It's not clear how the new camera will be oriented, but we speculate that they will be aimed off to the side to give the car a better view at certain intersections.

Some road junctions have objects such as buildings or bushes that can make it difficult for the vehicle to see with its B-pillar cameras. This often causes the vehicle to creep forward in order to gain enough visibility to proceed. Creeping too far forward sometimes causes the vehicle to be in a poor situation, where it has entered the path of other vehicles. These new cameras are likely aimed at solving this problem.

As previously reported, the repeater camera housing on the front fenders appears to be changing. It now appears to include a line that goes further back than the original. This could be part of the new design.

Project Highland will ship with Tesla's latest supercomputer, Hardware 4. The cameras themselves are expected to be the same cameras featured on HW4 Model S and Model X vehicles. They're estimated to be 5-megapixel cameras with an anti-glare coating. These cameras are significantly more advanced than the current 1.2-megapixel cameras in current HW 3 vehicles.

With the new front bumper cameras and the two additional side cameras, Tesla may now have everything it needs in order to provide a real birds-eye view that is often seen in many vehicles.

Sensors

In order to cut costs, Tesla is removing the vehicle's temperature sensor that is used to detect the temperature outside of the vehicle. Instead of using a temperature sensor, the vehicle will determine the exterior temperature based on its GPS location and weather data. This could lead to more accurate temperatures being displayed, as wind or other environmental factors can sometimes cause inaccuracies. However, owners will lose the ability to view the temperature in their immediate location, such as their garage.

Tesla is also making improvements to its GPS module which is expected to provide a more accurate location. In August 2022, Tesla applied for a patent on a multi-band Global Navigation Satellite System (GNSS) antenna. Various types of satellites and networks can be used to identify an object's location. GPS is just one of those networks. This new system allows Tesla to use other networks, besides GPS, in order to identify the vehicle's location. This could lead to faster location detection or higher precision.

Interior

Inside the vehicle, there will be some changes as well. However, don't expect a major refresh as we saw with the 2021 Model S, but it will still be noticeable. The wood trim is being removed and replaced with a fabric finish, possibly Alcantara fabric that Tesla already uses in the Model S and X.

The vehicle's dash will also receive a facelift, but we weren't given any details on what's changing with it. Again, this could be a way to simplify the manufacturing process instead of offering something new and improved.

There may be other interior changes, but these are expected to be the two bigger differences. We've been told that this refresh will be 'minor' and focuses on cost-cutting, however, it appears that Tesla is taking the time to upgrade the vehicle to its newest hardware and introduce new cameras, which will certainly be a highlight of the vehicle.

The Model Y project, codenamed Juniper is already underway as well, although it's expected to arrive after the Model 3 revamp. We expect the Model Y to undergo many of the same changes that we've outlined here.

Release Date

Overall, the Model 3 Highland's updates show that Tesla is always looking for ways to improve its vehicles and stay ahead of the competition. As is the nature of these things, some items could be subject to change. With these changes, the Model 3 will continue its success as one of the most popular electric vehicles on the market. Production for the vehicle is expected to start in the third quarter.

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.
