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.

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.

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.

Tesla Expected to Fix Cybertruck Charging and Regen Issue in Update 2025.2

BrianASilver3 / Tesla

Cybertruck owners in northern areas - especially those in Canada, have noticed slower charging rates on some vehicles. These owners are experiencing low charging amperage even when using a 48-amp Wall Connectors.

The 4680 cell - the Cybercell, seems to be sensitive to temperature changes and, as such, loses the ability to charge or discharge rapidly. Tesla accommodates this by warming the battery in advance of driving or while driving. However, there seems to be a software issue preventing the battery pack from warming up properly.

In addition, other users have noted that they don’t have regen braking due to the battery not warming up properly, even after driving. If you drive other Tesla vehicles while they’re cold-soaked, they will eventually warm up to offer you full regen and full performance. The Cybertruck, interestingly, will offer you full performance at cold-soaked temperatures as low as -20C (-4F), but will have regen unavailable in temperatures as warm as -5C (41F). 

Software Fix Confirmed

Brian Silver over on X reached out to Tesla Service with his findings, who confirmed that this is a known software issue that has now been validated. Tesla Service responded by saying that they’re hopeful a fix can be built into the 2025.2 software update. This is the first time we’re hearing about Tesla’s next major software update, which is expected to be released around the second or third week of 2025.

Tesla has also confirmed that this is not a physical issue with the heating system, so no repair is required for this one - it’ll be another OTA fix, just like many others.

We’re glad to see this one getting fixed so quickly. The issue appears to have started with the 2024 Holiday Update, or it could just be a coincidence since Cybertrucks begin to settle into Canada this year, where winters are much harsher and colder on average.

Workaround

We’re hoping to see this fix go out soon, as the current procedure to get around this is annoying. It requires you to set the navigation to a nearby Supercharger so that your vehicle will precondition the battery. You can stop the navigation to the Supercharger after 5-10 minutes, at which point the battery pack will be more than warm enough to charge at the full amperage of your home charger.

This workaround also resolves the issue of limited regenerative braking by warming up the battery pack sufficiently.

Tesla Introduces Multi-Vehicle Coordinated Light Shows [VIDEO]

Not a Tesla App

As part of Tesla’s Holiday Update, Tesla has introduced an awesome new feature - multi-vehicle synchronized Light Shows.

Now, you’re probably going to say: Wait! We’ve seen those kinds of light shows already.

And you’re not wrong - thanks to the hard work of people using the Light Show tool, you could synchronize light shows and run different shows on different vehicles. But this was a lot of manual, time-consuming work. Tesla now officially supports creating a light show involving up to eight vehicles.

Coordinated Shows

These new coordinated shows can be set up in the new xLights interface, making it far easier for Light Show designers to assemble everything. They’ll be able to edit and view multiple vehicles at the same time, synchronize them all together - and build variants with up to eight vehicles.

The output is still eight different Light Shows - which will still need to be put on USB flash drives and distributed to the correct vehicles in the correct order, but designers can now build a unified and coordinated light show. It could be possible to coordinate more than eight vehicles in a single Light Show - and we’re sure we’ll find out in the coming weeks what is possible with the updated xLights software.

Tesla showed off a great example below, putting together a jaw-dropping 8-vehicle Light Show using the new “Ready for Assault” show that arrived with the 2024 Holiday Update. Tesla has also gone ahead and contributed example Light Shows on Github to get Light Show designers familiar with the new process.

Everything New in Light Shows

Tesla’s light show feature received a massive update with this year’s holiday update, but we’re only finding out about some of the features now. Here’s a quick rundown of everything new in Tesla’s Light Show feature:

• Support the Off-road Lightbar for the Cybertruck

• Start, Stop, or Schedule a Light Show from the Tesla app

• Create longer Light Shows

• Two new songs, including Cyber Symphony and Ready for Assault

• Ability to control Ambient Lighting in 2024 Model 3 or Cybertruck

• Display color effects on the vehicle’s center screen

• Create Light Shows that involve up to eight vehicles

Cybertruck Lightbar Support

Another interesting addition is the recent support for the Cybertruck’s off-road lightbar. The off-road lightbar can be addressed in three zones - the forward main bar and left and right ditch beams. With the holiday update, Tesla also added the ability to program the vehicle’s ambient lighting, display color effects, and create longer light shows than ever before.

Tying everything together in this update is the ability to start, schedule, or stop a light show directly from the Tesla app.
