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.
The revamped Model 3 is known internally as Project Highland

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.

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.

Tesla’s first major update of 2025, software update 2025.2, is now rolling out to select vehicles in North America and Europe. While the update isn’t widespread yet, it is rolling out to most vehicles, including HW3 and HW4 cars. The Cybertruck and legacy Model S/X vehicles are currently the only vehicles that haven’t received this update.
Let’s take a look at everything we know that’s included in this update.
Third-Party Charger Preconditioning
First up, vehicles will now support preconditioning for third-party chargers. While this was previously available in Europe for approved third-party chargers that met Tesla’s strict standards, it’s now available in North America for the first time.
What’s New: When you navigate to a charging location, whether it’s listed in the vehicle’s charging locations or not, the vehicle will now precondition the battery for faster charging. It looks like the vehicle will automatically determine if the destination is an EV charging location and enable preconditioning. If the destination is a charging location, you’ll see a little banner show up, letting you know the vehicle’s battery is now being preconditioned. There isn’t a button to manually precondition the battery yet.
What’s Not Added: In Europe, the vehicle's charging filter shows approved third-party chargers. Unfortunately, it does not look like this is being added in North America, where Tesla only displays Superchargers and destination chargers. However, the above feature still applies in North America, where the vehicle will precondition the battery for fast chargers such as Electrify America.
The video below shows how the feature will work:
Muchos me habéis pedido que haga un vídeo de cómo se activa el precalentamiento en cargadores "no Tesla". Pues simplemente, en la ruta que elijáis, pulsáis sobre el cargador en cuestión y automáticamente se activa solo. pic.twitter.com/snMoPDx6Dr
Following up on the addition of rear cross-traffic alerts showing up as red indicators as part of the 2024 Tesla Holiday Update, Tesla is now adding an alert chime to go with it. Now, there is a visual indicator on the screen, as well as an audible indicator that a vehicle or object has been detected crossing behind you.
This is a great addition and almost looked like a glaring omission in the initial release of the feature. Tesla likely wanted to make sure the feature was working as expected in the wider fleet before introducing a more drastic alert.
The chime is enabled by default, but if you want to disable it, you can go to Controls > Safety > Rear Cross-Traffic Chime to disable it. Joe Mode will reduce the chime’s volume if you prefer that instead.
Improved Phone Key Reliability: Ultra-wideband (UWB) is an alternative to Bluetooth, which offers highly accurate positioning and tracking of devices. It uses about the same amount of energy as Bluetooth Low Energy but with increased location accuracy. By having your phone communicate with the vehicle over UWB, the vehicle knows exactly where your phone is in relation to the car, drastically increasing the reliability of your vehicle’s phone key.
Hands-Free Trunk and Frunk Opening: More precise location tracking enables new features such as Hands-Free Trunk and Hands-Free Frunk support. This feature has been available on iOS devices for approximately a year and will now be available on Android devices.
Supported Models: Unfortunately, not all models are supported, and your vehicle needs to have ultra-wideband sensors. Supported models include the 2021+ Model S and Model X, the 2024+ Model 3, the Cybertruck, and the upcoming 2025+ Model Y. Only the Model S, Model X, and Cybertruck support the hands-free frunk.
Supported Phones: Most recent Android phones support ultra-wideband, especially flagship devices, however, it’s not available on all phones. If you have a Google Pixel 6 or higher, Samsung Fold 2 or higher, Samsung S21+, or other recent Android phone, then your phone already supports ultra wideband.
Users with Android devices with UWB will initially be prompted to “Upgrade” their phone key when opening the Tesla app. This will switch your phone key from using Bluetooth to ultra-wideband. Once upgraded, you can go to Controls > Locks > Hands-Free Frunk / Trunk in your vehicle settings to enable the new hands-free feature. If you aren’t prompted for the upgrade, you’ll find it under Security & Drivers > Phone Key > Upgrade in the Tesla app.
Weather Information
With every Tesla update, there are smaller features, and this one is no different. In this update, the weather information is now displayed for both the final destination and any additional stops (waypoints) you have set along the way. Previously, the weather would only be displayed for your current location and your destination.
Battle of Polytopia
Next up, Battle of Polytopia is receiving another update. This time “The Forgotten” skin is being added for the recently-added Aquarion faction, adding some old-world Atlantis vibes to the fishy folk. Additional language support and balance changes are also included in this Battle of Polytopia update.
Cybertruck Charging Improvements
Last month we reported that The Cybertruck is expected to receive charging and regenerative braking improvements soon. Tesla was aiming at releasing these updates in the 2025.2 update, so there’s a chance that these cold weather improvements are also included in the 2025.2 update, but we won’t know for sure until the Cybertruck starts receiving this update in the coming days or weeks.
Other Features?
Since this update hasn’t rolled out to all models or regions yet, it’s possible we may see some additional features added in this update, although at this point, it may only be features for the Cybertruck or the legacy Model S and Model X.
Finally, as usual, Tesla includes minor fixes, performance enhancements, security fixes, and improvements. If you notice any undocumented changes, please let us know.
Well-known Tesla hacker Greentheonly has discovered a new FSD computer labeled Model Y “Reloaded.” This AI4 FSD computer differs from other Model Y Autopilot hardware which is usually just labeled “Model Y.”
Initially, it looks like this new computer may be for the just-announced refreshed Model Y Juniper, which is now open for orders in North America and Europe as well as Asia Pacific, but several features reveal it’s not for Tesla’s upcoming best-seller.
So, with that said, put on your detective hats, we’re going for a little sleuth into what exactly this “Reloaded” computer could be used for.
Model Y Reloaded Computer
The AI4 computer is the brain behind Tesla’s FSD. It is the Autopilot computer, where all the vehicle’s cameras connect, enabling real-time data processing and analysis.
This particular unit is not the standard FSD unit that’s being shipped with the current, now “first-gen” Model Y. The biggest sign that it differs from the current AI4 computer is that it features a connector for the front bumper camera. While the 2024 Model 3 was expected to come with a front bumper camera, it was only ever available on the Cybertruck and will soon be available on the new 2025 Model Y.
This is similar to the physical connector for the front bumper camera present in newer iterations of the Model S and Model X computers. These vehicles were originally slated to get a bumper camera last year, but that hasn’t happened yet. We reported back in 2022 that they received the additional camera hook-ups but no camera.
Tesla recently issued a recall for the AI4 computer, citing physical and software issues that could cause a potential short on the board. According to Green, this board is not the recalled unit but could instead be a replacement unit. However, why the board includes a front bumper camera connection remains a mystery.
Not a Juniper FSD Computer
We know that this isn’t the correct part for the refreshed Model Y Juniper because it lacks a connector for the secondary rear screen in the upcoming model.
Additionally, Tesla has labeled this computer unit as “MY Reloaded” - previous versions of the computer for the Model Y were listed as just “MY.” In addition, all the other computer versions have been pulled from Tesla’s Electronic Parts Catalogue - only this one is now available as Part #2003160-S0-E.

Speculation
This new FSD hardware doesn’t appear to match the current or new Model Y, so what could it be? Well, there are a few things here. Tesla wouldn’t bother populating that front bumper camera slot for no reason - and this computer is a slightly different form factor than the one that goes in the Model S and Model X - so they’re not just sharing parts between the Model S and Model Y.
The most likely scenario is that Tesla is planning to replace any faulty AI4 computers with this updated part. But could Tesla be open to offering a retrofit for the front bumper camera? It’s important to note that this is not the hardware upgrade that many HW3 owners are waiting for. It is a different form factor than the HW3 computer and wouldn’t fit in HW3 vehicles. If anything, this is a potential replacement for the AI4 computer to support forward compatibility if FSD ever requires a bumper camera.
The full computer.

Bumper Camera Retrofit?
Is Tesla planning to offer a front bumper camera retrofit? Maybe. Tesla doesn’t typically offer retrofits. They did for several items in the past, but they have largely stopped doing so.
Tesla included a front bumper camera on the refreshed Model Y Juniper, as well as on the Cybertruck - and it could be extremely useful for both Actually Smart Summon and FSD to remove the frontal blind spot.
However, it could be an optional feature rather than a retrofit feature. Until FSD Unsupervised arrives, we won’t know for sure whether a bumper camera is required.
For now, it would be best to keep an eye on this. Just like the Model S and Model X having the slot populated, it may not necessarily happen, but it leaves the door open for a future upgrade if necessary.
