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.

Tesla Appears to Have Updated Its Navigation Voice in Newer Vehicles [VIDEO]

It looks like Tesla has updated its English voice that’s used during navigation guidance on newer vehicles. Many users have noted a change in the pitch and speed of the spoken text when using Tesla’s navigation system. Right now, we’re not sure whether this voice change is an indication of a larger change that’s coming, a minor tweak for better clarity, or just a bug.

Tesla Voice Guidance

A reader, known as FSDTester#420 on Tesla Motors Club recently reached out to us to report a new nav voice. He took delivery of a new Tesla and immediately noticed that the navigation’s voice was much better than his other Tesla. The voice is noticeably faster and appears to have fewer pauses, making it sound more natural.

After posting his experience on Tesla Motors Club, other readers chimed in saying they had the same voice in their new vehicle. The change does not appear to be affecting older vehicles, so it’s not clear what’s driving this change. The user has the same navigation map data and software version as many others, so it’s not clear whether this is an improvement or simply a bug.

Tesla Smart Assistant

It looks like Tesla will be updating its Voice Commands system in the future, with Musk recently saying that Tesla will support Grok AI in the car. Tesla’s current voice commands are limited and require you to say phrases in a very specific way, although they do give you access to the most common features (Top 10 Tesla Voice Commands).

Overall, voice commands are not very smart – and they’re nothing like using Google Gemini with Voice or other modern AI-based assistants. Back in January, Tesla began implementing a smart assistant in China – which brought things beyond just vehicle control, like weather updates, stock market information, language translation, and even poetry.

However, this never made its way out of China, even though Tesla’s smart voice assistant has been sitting dormant in the software for quite a while. It looks like we’ll get a wake-word, similar to the common “Hey, Tesla” – it could even be “Hey, Grok” – if we get full Grok integration as previously hinted at by Elon Musk earlier in 2024.

Either way, for now, there haven’t been any significant changes, but this voice change we’re seeing could be related to Tesla’s upcoming smart assistant feature, where they may need a more capable, more natural sounding voice.

Tesla Confirms Hardware 3 is Robotaxi Ready

Tesla took to the Hollywood stage at ‘We, Robot’ last week, and lots of interesting new information has been revealed. One of the most interesting items that many people have been wondering about is Tesla’s plan with Hardware 3.

Tesla previously mentioned that there would be a divergence between AI4 and Hardware 3, but so far, Tesla has kept Hardware 3 going strong with code optimization and model improvements. However, it is pretty evident that Hardware 3 is hitting its computing limit, as Tesla sees that AI4 has much more capability to unlock.

However, they have said they’ll do their best to continue to support the millions of vehicles on the road today running Hardware 3. Tesla’s Cybercab, on the other hand, will be running on AI5, an as-yet-unreleased hardware stack that promises to greatly improve and expand the available compute performance.

Hardware 3 Robotaxi

Lars Moravy, the Vice President of Vehicle Engineering at Tesla, spoke to attendees at We, Robot, and mentioned that Hardware 3 will be Robotaxi capable (at the 7:25 mark). That means that it will be capable of Unsupervised FSD, according to Tesla. Kim Java, a YouTuber focused on Tesla and EVs in general, posted this video featuring her speaking with both Lars, as well as Franz Von Holzhausen, the Chief Designer at Tesla.

Given Lars and Franz both seem confident in the assertion that you can remove a HW3 vehicle’s steering wheel and get it Robotaxi capable, it definitely seems that Tesla intends to continue supporting HW3 well into the future.

So, while Hardware 3 might be reaching its limits, the company's not giving up on it yet. With this, they’ve essentially confirmed that the millions of vehicles with Hardware 3 won't be obsolete anytime soon when it comes to Robotaxi and Unsupervised FSD. 

Tesla is continuing to demonstrate its commitment to its customers and its vision of the future, and we’re looking forward to seeing what’s next on the list.
