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.

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 Dan W Priestley attended the Advanced Clean Transportation (ACT) Expo in Anaheim, California, and provided an update on Tesla’s Semi truck program. The presentation covered several key developments on the status of Tesla’s Nevada Semi Factory, refinements to the Semi, and Tesla’s plans for charging and ramping production through 2026.
Let’s dig in and take a look at everything that was captured by the Out of Spec team at ACT Expo. The original video is embedded below if you’d like to watch it.
Semi Factory & Production Ramp
Priestley reaffirmed the timelines mentioned during Tesla’s Q4 2024 Earnings Call that Tesla will scale Semi production in 2026. To achieve this, Tesla has been actively building and expanding the Gigafactory Nevada site, specifically to support the production of the Tesla Semi. The dedicated Semi facility will have a targeted annual capacity of 50,000 Semi trucks.
Following the beginning of production, Tesla will utilize the initial trucks to integrate into its own logistics operations. This will serve as both a final real-world testing ground as well as an opportunity for Tesla to gather data internally. Tesla plans to begin subsequent customer deliveries throughout 2026 as the ramp-up continues.
Reuters also reported that Tesla is hiring over 1,000 new employees at the Semi Factory to begin the rapid ramping of the program.
Semi has already amassed 7.9 million miles with Tesla’s current testing and operational fleets, providing some real-world data and testing. Feedback for the truck has been exceptionally successful, with many drivers praising the Semi’s performance and comfort.
New Tesla Semi Features
Of course, it wouldn’t be a Tesla keynote without showing off some new things. The Semi will be available in 500-mile and 300-mile range configurations, now featuring updated mirror designs and a drop-down glass section to improve visibility and allow easier interaction with external elements—such as control panels at ports, for example.
New Electric Power Take-Off (e-PTO)
The Tesla Semi will also feature a new capability called Electric Power Take-Off, or e-PTO system. Similar to the PTO systems found on other vehicles, this will allow the Semi’s high-voltage battery to power auxiliary equipment at variable voltages. That includes being able to power things like climate-controlled reefer trailers, potentially replacing the noisy and polluting diesel generators traditionally used for this purpose.
Charging and Batteries

Tesla is also working on an updated battery pack design for the final production design of the Semi. This new pack is designed to be more cost-effective to manufacture. The battery pack itself is slightly smaller than before, but the truck maintains the same level of range through efficiencies. Dan also confirmed during his keynote that the battery cells for the Semi will be sourced domestically inside the United States, helping to alleviate potential burdens due to tariffs.
On the charging front, Tesla is using MCS - the Megawatt Charging System - capable of 1.2MW - and designed specifically for Semi. The system uses the same V4 charging hardware found at Supercharger sites but focuses on that larger power output. Alongside a smaller physical footprint, Tesla will be able to configure these V4 cabinets for either dedicated Semi charging or for shared power scenarios with regular Superchargers. Tesla is also working on an integrated overnight charging product, but Tesla isn’t ready to talk about it yet.
46 Semi Charger Sites Coming

Finally, Tesla has made substantial investments in a public charging network for the Semi. There are currently 46 sites in progress throughout the United States, and plans for significant expansion throughout 2026 and 2027. These sites are strategically located alongside major truck routes and within industrial areas to support long-haul and regional operations. Tesla is aiming to offer the lowest possible energy costs to operators to help incentivize adoption.
This was one of the best updates to the Tesla Semi we’ve received since its initial unveiling. It seems that the Semi will receive a big portion of Tesla’s attention in 2026, while Robotaxi and FSD Unsupervised take the stage this year.
The Tesla Semi has the potential to transform transportation even more dramatically than EVs already have, serving as a testament to Tesla’s mission to electrify the world.
Sentry Mode is an invaluable tool for owners - capable of keeping the vehicle safe and secure even when you’re not around. This is especially true in recent times, with the misguided and unfortunate incidents surrounding Tesla ownership, including damage to Tesla vehicles, showrooms, and Superchargers.
B-pillar Camera Recording and Dashcam Viewer
With the 2025 Spring Update on 2025.14, Tesla is expanding Sentry Mode’s functionality for certain vehicles with some much-needed changes. Sentry Mode and Dashcam can now record footage from the vehicle’s B-pillar cameras. These cameras are located on the side pillars of the vehicle, between the front and rear doors.
This adds two crucially needed viewpoints, making Tesla’s Sentry Mode a truly 360-degree security system. These cameras also provide the best angles for capturing license plates when parked, so they will be greatly appreciated by owners in the event of an incident.
These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view. It also allows users to jump back or forward in the video in 15-second increments.
However, to the disappointment of many owners, not all vehicles are receiving these updates due to the additional processing power needed.
Limited to Hardware 4 Vehicles, Ryzen Isn’t Enough
We have confirmed that Tesla is only adding the additional camera recording and improved Dashcam Viewer on hardware 4 (HW4 / AI4) vehicles. The newer hardware presumably has the additional processing power and bandwidth needed to handle recording and saving the two additional video streams during Sentry Mode and Dashcam.
For the time being, owners of HW3 vehicles are not receiving this feature. This includes all vehicles with HW3, even those with AMD Ryzen infotainment systems. If you’re not sure whether your vehicle has HW3 or HW4, you can refer to our FSD hardware guide.
While there’s no doubt that recording two additional camera streams would be more computationally intensive, we hope that Tesla adds the improved Dashcam Viewer to HW3 vehicles in a future update.
Cybertruck Also Missing Improved Sentry Mode
Surprisingly, and most confusing for many - is the fact that the Cybertruck is also not receiving the improved Dashcam Viewer and B-pillar camera recording with this update. This struck us as odd, especially since the Cybertruck is currently the only vehicle with the improved, more efficient version of Sentry Mode.
Every Cybertruck is equipped with HW4 and AMD Ryzen infotainment units, so this clearly isn’t a hardware restriction. It’s possible the more efficient Sentry Mode is playing a role here due to the infrastructure changes. However, we expect Tesla to address this in a future update and eventually release these features for the Cybertruck as well.
Given the Cybertruck’s high visibility and its status as a frequent target for both positive and negative attention, many owners hoped that the Cybertruck would be one of the vehicles to receive this feature.
Adaptive Headlights
Tesla finally started rolling out its adaptive headlights in North America. While the new Model Y already came with the feature when it was released last month, other vehicles with matrix headlights are now receiving the feature in the Spring Update.
All vehicles with matrix headlights are receiving this feature, which includes the new and old Model 3, first-gen Model Y, and the new Model S and Model X.
If you’re not sure if your vehicle includes matrix headlights, check out our guide. What’s interesting here is that older vehicles that were retrofitted with matrix headlights due to an accident or user replacement are also receiving the adaptive headlights feature.
Legacy Model S & Model X
As with most updates, the older legacy Model S and Model X are not receiving all the features included in this update. Unfortunately, some of the features, which include the Blind Spot Camera on the instrument cluster, Save Trunk Height Based on Location and Keep Accessory Power On are limited to the new Model S and X.
Legacy S and X models will receive the Alternative Trip Plans feature, Avoid Highways (Requires Intel MCU) and the Keyboard Languages feature.
These vehicles are also receiving all the features in the Minor Updates section except for the visualization showing how far the door is opened, which is exclusive to the Cybertruck. These additions include improved music search results, contact photos in the phone app, automatic connecting to hotspots, the ability to show third-party chargers, view Supercharger amenities, and various improvements to music services.
While many users will be disappointed not to receive the B-pillar camera recording and Dashcam Viewer improvements, it’s important to remember that Tesla typically does a great job at bringing features to older vehicles, at least with the Model 3 and Model Y. If a feature isn’t added, it’s usually due to a hardware limitation.
