Tesla Software Update 2025.8 Released to Employees—What May Be Included
Tesla has just released software update 2025.8 to employees for testing. This is the norm for Tesla, as they release software updates to their internal audience for testing before beginning a rollout to the public.
While we don’t know what’s in this update just yet, there are several features we know that are coming up and could be included.
Adaptive Headlight Support
Tesla’s VP of Vehicle Engineering, Lars Moravy, recently confirmed that the refreshed Model Y will receive adaptive headlights, as well as the matrix headlight functionality. In fact, it’ll be the first vehicle in Tesla’s line-up that will support matrix headlights in North America.
The feature just received approval in the United States recently and will be rolling out to all Tesla vehicles that have matrix headlights sometime soon. That includes support for the Cybertruck, and Model S, Model X, and Model 3 as well.
Grok Support
xAI recently launched the newest version of their smart assistant - Grok 3. That same smart assistant is eventually supposed to make its way over to Tesla vehicles, according to Elon Musk.
The new smart assistant is expected to provide quite a bit of new functionality when it comes to intelligently handling your voice commands, and it could be included in this upcoming update, although a Spring launch is more likely. Grok 3 just launched voice support last week.
Cybertruck Updates
Siddhant Awasthi, Tesla’s Cybertruck program manager, recently confirmed that a new set of suspension controls are on their way to the Cybertruck. As of now, you can only adjust the vehicle’s height in the vehicle.
We’re hoping this new feature allows access to vehicle height adjustments from the Tesla App, as well as unlocking some new vehicle drive heights in general.
One of the items that didn’t manage to make it into 2025.2 was the Cold Weather Fix for the Cybertruck. Certain Cybertrucks have issues reaching max charging speed due to not properly pre-conditioning in cold weather when plugged into an L2 charger, and some Cybertrucks are also seeing drastically reduced regen in those temperatures, too. Hopefully, this will also get tackled in update 2025.8.
In-Cabin Radar Support
Tesla has started to activate the in-cabin radar in older Model Y vehicles that have it equipped, but it has confirmed that other equipped models will eventually also receive support. The in-cabin radar replaces the front seat occupancy sensors and instead uses the radar to more accurately detect the presence of humans.
We expect vehicles to also start supporting rear-seat passenger detection in Q3 2025.
New Nav Routing Options
New navigation routing options were released for Chinese users in early January, which included new options such as Least Congestion, Prefer Highways, and Lowest Tolls. It also brought with it a new Service Area modal, which shows what amenities are available at various vehicle service areas on the highways.
We’re hoping to receive at least some of these features in North America and Europe sometime soon. We’ve been waiting for that Avoid Highways option for what seems like an eternity now.
Trailer Profiles for Model S, X, Y
Trailer Profiles launched with the Cybertruck, and are, for now, an exclusive feature. Hopefully, the ability to save trailer details will make its way to other tow-hitch-compatible vehicles. Trailer Profiles allow you to save information about your trailer, including type and braking settings - which can help more accurately estimate energy usage. In addition, it is an easy way to track trailer mileage.
Custom Vehicle Wraps for Models S, 3, X, Y
With the 2024 Holiday Update, Tesla gave the ability to wrap the Cybertruck in whatever style you wanted - in the vehicle visualization. Many people used it to match the actual wraps or decals they had on their vehicles. This functionality also covered license plates - including custom styles, numbering, and lettering.
Tesla later confirmed these wrap and license visualizations would eventually roll their way out to the rest of the fleet, so we’re expecting them to either in 2025.8 or shortly after.
Sentry Mode Efficiency Update
Back in November 2024, Tesla made some significant improvements to the Cybertruck’s Sentry Mode. They achieved an almost 40% reduction in the overall energy usage of Sentry Mode by making better use of the onboard vehicle compute.
These updates should soon roll out to the rest of the fleet, greatly improving Sentry Mode efficiency.
Release Date
In general, Tesla takes between one to two weeks to release an update to customers after sending it to wave 1 employees. That timeline isn’t firm - so sometimes it could take five days, and sometimes it could take the full two weeks, but the clock is ticking for this one now. We should have the full release notes in the next week or two and then our first look at some of the new features in the following days.
Update: Tesla update 2025.8.3 has now started rolling out to employees. This is often an internal bug fix release before the update starts going out to the public. We’d expect Tesla to release this update to the first batch of vehicles in the next few days to a week.
