The improvements in v12.5 are supposed to focus on rarer, more complex situations and vehicle-to-fleet communication. Tesla’s Autopilot lead, Ashok Elluswamy, also mentioned that FSD would gain the ability to go in reverse around this time.
Merge City & Highway Stacks
FSD v12 has been a multi-stack setup so far, with a city-streets stack that is end-to-end, and an older highway stack that was carried over from v11. FSD v12.5 will once again merge the city/highway stacks according to Musk, who confirmed the feature yesterday. That means that there will no longer be an implicit highway stack.
This could cause some regressions during highway driving, similar to the ones we experienced when Tesla first merged highway and city stacks back in FSD v11. Ultimately, when the issues were ironed out, we ended up with a smoother and better Autopilot experience on the highway. When FSD v12.5 rolls around, we may see some similar issues but expect FSD v12.5 to do to highways what v12 did for city driving.
Vehicle-to-Fleet Communications
Tesla’s FSD relies heavily upon maps, with the mapping information designating routing and lane changes. When vehicles encounter difficulties, they are unable to communicate that back to the rest of the fleet. This results in every vehicle encountering the same problem. With FSD V12.5, vehicles will be able to communicate road closures or other obstacles back to the rest of the fleet in real-time. This will turn FSD into software that’s constantly improving as the fleet gathers more data, instead of having to wait for a software update.
Cybertruck Finally Gets FSD
In a recent post on X, Musk also confirmed that V12.5 will finally bring FSD to the Cybertruck. Currently, all Cybertrucks only have access to Traffic Aware Cruise Control (TACC). Autopilot and FSD capabilities should arrive alongside all the other features.
Actually Smart Summon
Musk has talked quite a bit about Actually Smart Summon. With FSD 12.5, the new vision-based summon may finally be released. This will introduce Smart Summon capabilities to vision-only cars for the first time. However, it’s expected to be a drastic improvement for all vehicles in similar ways to the new Autopark. The new summon has been tied to the ability to move the vehicle in reverse by Tesla’s Autopilot lead, so expect either both of them to arrive in FSD 12.5, or be held off for a later release.
Release Date
Musk originally mentioned that FSD V12.5 would be released in late June, however, there were several delays with FSD 12.4 and that time frame has now come and gone. FSD 12.4 was initially released in May 2024, but it went through several lengthy revisions before it was introduced to public testers. Going by that time frame, it appears that FSD 12.5 was expected to be released about 4-6 weeks after FSD 12.4. If FSD 12.4.3 is finally got a good spot, we could see FSD 12.5 become available in the next 4-6 weeks or about late August.

Rendering of what Tesla's license plate feature could look like
Not a Tesla App
Tesla update 2024.38 has started rolling out to several regions and vehicles. Thanks to Tesla hacker Greentheonly, we have a behind-the-scenes look at some new features coming to Teslas.
License Plate Display
According to Greentheonly, it looks like Tesla may soon let you display your actual license plate in the vehicle’s visualization on the screen. In our article, The Most Request Tesla Features, several readers suggested displaying the vehicle’s license plate in the visualization instead of a blank, white plate.
It looks like Tesla will be doing just that, at least in China. Green found references that appear to conclude that you’ll be able to display your vehicle’s plate on screen. This will likely be user input, so you could have it say anything you’d like, and it doesn’t have to be your actual license plate.
For many owners, who may find it difficult to remember their license plate, this could serve a practical purpose in addition to adding to the visualization's realism.
While Green was only able to say it’ll be available in China, we expect this is due to China’s software development team working on it and that it’ll eventually be released worldwide.
While code for this feature was found in update 2024.38, we may not be turned on in China yet. We suspect this feature may be a strong candidate for Tesla’s upcoming holiday update.
FSD Hardware Version Display
As part of the 2024.38 update, Tesla has now made it easy to determine whether your vehicle includes Hardware 3 or Hardware 4. You can now simply navigate to Controls > Software and tap Additional Vehicle Information. In addition to other hardware information about your vehicle, your Autopilot hardware version will now be listed as well.
You can see whether your vehicle has HW2.5, HW3, or AI4. This in-car display is useful, but if you don’t have access to the vehicle, you can always use our guide on how to determine the hardware version of a Tesla.
New Battery Health Test & Service Mode Improvements
Green found some additional things as well. There’s a new and improved Battery Health Test. The new test will show you how your car scores compared to similar vehicles in the Tesla fleet.
In addition, maintenance records can now be permanently stored “in the car.” It doesn’t appear that this feature is activated yet, but it’s likely in active development with some parts leaking out in the 2024.38 update.
Tesla has included various Service Mode improvements and new visualizations in this update.
Mr Li on X came across some covered-up Project Juniper vehicles recently and he managed to get various shots of the vehicle.
Juniper Images
This front image reveals what looks like two rows of lights, possibly confirming the front light bar for the Model Y refresh — similar to the one on the Cybercab.
The rear side has a lot of lights on it!
Mr Li on X
The rear side shows a ton of brake lights, but it’s not clear why. While it looks like the Model Y refresh will also feature a rear light bar similar to the Cybertruck, there isn’t strong evidence of that in this photo.
Mr Li on X
There's an obvious set of lights at the bottom, so it looks like the Model Y refresh will be similar to the new Model 3 where the bottom lights can operate as brake lights when the one-piece tail lights and trunk are up.

In the last photo, we see that the overall form factor of the refreshed Model Y will remain unchanged, and Tesla is focusing the changes on the front and rear ends of the vehicle, much like the Model 3 refresh. However, in this one shot, we can also see what appears to be red light leaking out of the rear camera cover opening, possibly due to the rear light bar.
The Model Y is not only Tesla’s best-selling vehicle but also the world’s best-selling car in 2023. This year, it’s expected to be the best-selling vehicle in the United States and again in the world, so this refresh will be huge for Tesla.
@DominicBRNKMN made another fantastic set of concepts based on these new images. Given he had the most accurate Model 3 Highland concept before the official launch, we’re pretty sure his latest work be close here as well.

We’re super excited to see the eventual reveal of Project Juniper, which is expected in the first half of 2025. However, expect to see a few more leaks before production kicks off at Giga Shanghai.
