A few weeks ago, we reported that Tesla will deliver its first HW4 vehicles without the suspected additional cameras. Shortly after, Twitter user Kilowatts ventured into one of Tesla’s vehicle lots and was able to snap photos of some of the first Teslas with hardware 4.0.
Delivery of HW4 Model X
A poster on Reddit shared pictures and video of his 2023 Model X delivery, showcasing hardware 4.0. According to their post, the vehicle was built on February 25th and delivered March 5th, a mere 10 days after being built.
Software Still a Work In Progress
Teslas with hardware 4.0 are missing visualizations, TACC and Autopilot right now

However, several features on his vehicle are currently unavailable as Tesla appears to still be developing and testing software for HW4. These features include almost everything that utilizes the vehicle's cameras, including Autopilot and Traffic Aware Cruise Control (TACC). Full Self-Driving Beta (FSD Beta) is also disabled.
The visualizations on-screen are also absent, the vehicle displays almost no visualizations of any kind. According to the author of the post, only road markings are visible.
The vehicle does not show any details confirming it has HW4 in any of the usual places such as the software tab, in the 'additional vehicle information' dialog, or in Tesla's Service menu. However, the owner says that Tesla themselves confirmed that the vehicle is equipped with Tesla's latest FSD hardware and the author's photos confirm the presence of the new cameras.
HW4 Timeline for Other Teslas
While Tesla continues to work on the software for HW4, we’re anticipating the Model 3 and Model Y vehicles to follow with HW4 deliveries at some point this year. Tesla’s “Project Highland” is making way, but Tesla may add hardware 4.0 to the Cybertruck first, as the new hardware may be constrained due to ramping production.
Retrofits for HW4
Tesla CEO Elon Musk has said that HW4 will not be available for retrofits. He’s said that as long as HW3 remains safer than a human then there’s no need for an upgrade. The entire computer has been rebuilt and rearranged, making it much more difficult to pop it into HW3 vehicles.
After Greentheonly’s leak about HW4 last month, Munro Live shared an in-depth video explaining every detail of HW4 and what to expect. Additionally, they went over why retrofits are not feasible.
Update
Update: The owner, Jason has updated their Reddit post to provide an update on some of the missing ADAS features. He noticed that his rear camera was failing and that he could reset it in Tesla's Service Mode.
Resetting the camera would bring it back online, however, it crashes again just minutes later. Jason was able to have the camera online long enough to confirm that Autopilot was available if the camera was working. However, as soon as it crashes, Autopilot and other features would go offline, even if they didn't completely depend on the rear camera.
For example, visualizations would appear, but as the rear camera crashed, they would completely disappear, even if the objects that were in front of the car.
Jason said that Navigate on Autopilot, TACC and visualizations appeared to be available while the rear camera was online, but it wasn't clear whether all features were available such as AutoPark, Summon and FSD Beta.
This appears to be a software-related issue, but it's not clear at this time whether it's affecting everyone with hardware 4.0 or if it's limited to some vehicles.
Update 2
Update 2: The vehicle in question has now received another software update, version 2023.201, which contains "bug fixes."
This update has fixed the issue with the rear camera and the vehicle has regained access to Autopilot, TACC, vehicle visualizations and other features, although AutoPark and FSD Beta are still unavailable. This update addresses the larger concerns and reestablishes the major features of the vehicle, however, we hope the additional functionality is restored soon.

Last night on X, Elon Musk confirmed that Tesla will be expanding the service area for its Robotaxi Network pilot in Austin, Texas, this coming weekend. This is the first official confirmation we’ve had of a date for expansion, following news that Tesla is hiring more Vehicle Operators and plans to expand the Robotaxi supervisor ratio in the coming months.
This is a sign of Tesla’s confidence in the Robotaxi pilot program and its current FSD builds.
Expanding to a larger service area in Austin this weekend
The announcement confirms the sights we’ve been seeing of Tesla’s engineering validation vehicles focusing on areas outside the initial geofence. This public test shows that Tesla was likely finalizing FSD builds and gathering the necessary safety data to push the boundaries for the service, and this upcoming weekend’s expansion will be the first direct result of that work.
Given the increase in service zone size, this expansion will also likely include the addition of more vehicles to the initial Robotaxi fleet of approximately 20 vehicles. We expect the new number to be anywhere from 30-50 vehicles serving both the original and new areas, combined, based on Tesla’s previously expected rollout schedule.
What to Expect
While the exact new boundaries haven’t been released, it is almost certain that the expansion will include the South Congress Bridge and the downtown core areas of Austin. Expanding into a dense urban zone will include more complex intersections, heavy pedestrian traffic, and a unique road layout. That is a major vote of confidence for Robotaxi FSD’s capabilities.
The expansion will also help Tesla to close the service area gap with Waymo, its primary autonomous competitor in the city. This quick expansion is a sign of just how scalable Tesla’s vision-only approach is, versus Waymo’s arduous and drawn-out mapping processes.
We also expect that with this first service zone expansion, Tesla will continue to invite more people to its Robotaxi Network in the coming weeks. Tesla has already sent out various rounds of events, as they’ll need users to continue using the system. If you’re waiting for an invite, it may be time to start getting excited about the next rollout.
We’ve been hearing about Grok, xAI’s AI assistant, coming to Teslas for almost two years now, but this is finally coming to fruition soon. XAI unveiled Grok 4 last night, but the entire stream didn’t mention Teslas. However, Musk later posted on X that Grok will arrive in Tesla vehicles “by next week.”
Between leaks and the Grok mobile app, there’s a lot we already know about Grok, but there are a few missing pieces that will be cleared when it finally arrives.
Next Week, or Next Next Week?
Musk said that Grok would arrive by next week, meaning it could arrive before then. However, based on how Musk typically states Tesla timelines, there are a few things to consider that give us a better idea of what to expect.
First, whenever Musk posts a Tesla timeline on X, he typically means when it’ll be released to employees and not a public release. Expect this to be the same thing.
Tesla releases software updates to employees first for a final round of testing before starting a gradual release to the public. Sometimes issues are found, especially with FSD updates, and the update needs some fixes before being released publicly. So expect employees to get it by next week, and not necessarily normal Tesla owners.
The second part to this is that Tesla always rolls out their updates gradually, so when it does finally arrive, it’ll only be available on a small percentage of vehicles. Tesla will gradually monitor issues and logs, continuing the rollout as long as no major issues are found.
Which Software Update?
The entire Grok UI was already included in software update 2025.20, but it’s not exposed to users. Typically, a new feature like Grok requires a vehicle update to be added; however, this version may be different, as it’s locked behind a server-side configuration.
Tesla likely has the ability to enable it for all supported vehicles with a simple switch. However, we feel more confident in it being rolled out in Tesla’s next major update, which is likely to be 2025.24 or 2025.26. Rolling it out in a new update aligns with how Tesla has historically introduced features.
If they turned it on for everyone at the same time, they could be exposing everyone to potential new issues, rather than only a smaller segment of users. While Grok is now well-tested through X and the Grok app, there are several elements that are new in Teslas, likely including the ability to control various vehicle functions, such as opening the glove box or other capabilities that voice commands are currently capable of. The Grok interface in the vehicle is also entirely new and may have some bugs associated with it that will need to be addressed, especially if they impact other features.
What we can likely expect is that Tesla will make some tweaks or bug fixes to Grok with the next major update that weren’t included in update 2025.20 and they’ll begin rolling it out to employees and then customers.
Supported Vehicles
Speaking of supported vehicles, thanks to the behind-the-scenes look at Grok, we have a good idea of the vehicles that will be supported. Tesla uses the same code for most of its vehicles, but then it’s compiled for each type of hardware. However, only the needed code is compiled for each vehicle, meaning that some pieces are left out entirely. Unfortunately, Grok code is not included in Intel software builds, meaning that only AMD Ryzen-based vehicles will receive Grok, at least initially.
We’ve seen Tesla go back and add support for Intel vehicles after it initially released a feature for AMD vehicles. We saw this with the weather radar overlay and several other features in the past. However, Tesla has been developing code with web technologies lately. While this makes development easier, it just doesn’t perform as well on the slower Intel hardware, causing it to be left out. We saw this with the new Dashcam Viewer, which is entirely coded in HTML, CSS, and JS. The new viewer was available on HW3 and HW4 vehicles, but only those that included the Ryzen infotainment processor.
Grok is coming to Tesla vehicles very soon. Next week at the latest.
There’s a lot we’re expecting in Grok for Teslas. Some people will absolutely love it because it’ll completely transform their drives from a singular experience to feeling like they have a knowledgeable person sitting right next to them. Given the recent controversies surrounding Grok, some people will strongly oppose it. Hopefully, Tesla makes it easy for those users to turn off Grok.
The voice command system, which is activated through the steering wheel, is expected to be replaced with Grok. This will mean that you’ll be able to talk to your vehicle much more naturally, rather than having to remember specific syntax and commands, which should be a major improvement.
We’re personally looking forward to just being able to ask questions that pop into our heads while driving, such as What’s the date of Tesla’s next event, or How many miles away is Mars? Knowledge will be available at the touch of a finger and more accessible than ever.
Grok is also expected to support continuous conversations, meaning that you’ll be able to hold a conversation with it and go back and forth about a certain topic. While there are hints of a wake word in the code, for now, it seems like you’ll press the steering wheel button once to activate it, and then again to turn it off.
For those excited about AI and Grok, this will be one of the biggest additions to Tesla’s software in years, possibly only rivaled by the Dashcam / Sentry Mode feature and FSD Beta.
It shouldn’t be long now before we all have a chance to try it out for ourselves.
