Tesla recently released Trailer Profiles for the Cybertruck with software update 2024.45.32.5. Trailer Profiles were spotted in decompiled code late last year but weren’t enabled until this release.

Back then, all we knew was that the new feature was coming soon, and we’d be able to make unique profiles per trailer to better track range, consumption, and trailer mileage. However, now that the feature has been released, we have our first look at what Tesla has put together.

Trailer Profiles

The new Trailer Profiles feature is available in the Towing & Hauling menu on the Cybertruck. However, it’s expected to arrive in other vehicles later this year.

Within the new menu, you’re able to create new trailer profiles, keep track of several unique values, and also adjust trailer-based settings. For now, you can have up to 20 unique trailers, which will enable you to build profiles for both loaded and unloaded variants of whatever you’re towing.

Supported Cars

While Trailer Profiles is currently exclusive to the Cybertruck, we expect other models that are capable of towing to receive the feature as well. Tesla typically likes to release features in smaller batches and limit their release. Sometimes this is done regionally, while other times, it’s done by model. Tesla has tried other ways to limit a feature, but these are typically the methods used. Future support should include the Model S, Model X and Model Y.

Trailer Setup

You can set the following settings when setting up a new trailer:

Trailer Name: Name your trailer just like you would your vehicle or your Tesla profile. This will make it easier when you want to switch to that profile later.

Type: You can select between an open or enclosed trailer variant here to help the system adjust for range estimation better.

Trailer Mass: You can put in the weight of the trailer. This value can also be adjusted later on, so you can update it on the fly.

Dimensions: You can put in the dimensions of your trailer. For now, this appears to be locked to the imperial measurement system, but we’re sure metric support will be available soon.

Mileage: Finally, you can add in the mileage of your trailer as the starting mileage, if you know it. This value will also adjust automatically as you tow the trailer, so there’s no need to manually update it in the future. This feature, along with better range estimations, are probably the two biggest reasons to use Trailer Profiles. You’ll now have a better idea of when to check your trailer’s tires and brakes based on mileage.

Settings Menu

A batch of trailer-towing-specific settings is also available in the Towing and Hauling Menu, enabling you to fine-tune your trailer tow setup. These are saved per trailer profile, so you can quickly get going once you select your trailer.

Trailer Brake Gain: This is a sliding scale between 1 to 10 that calibrates the overall degree of braking applied. 0 applies no brakes, whereas 10 applies the full brakes.

Trailer Brake Boost: The brake boost option increases the reaction speed of the trailer brakes. By default, Tesla recommends the Low option, as braking will become much more harsh at the higher settings.

Adaptive Regenerative Braking: At the start of the drive, your vehicle will automatically estimate the total load being towed to calibrate the proper level of regenerative braking. Regenerative braking starts at a “standard” level and increases as the vehicle learns the trailer’s weight and cargo.

Trailer Auxiliary Power: Enables or disables auxiliary power to your trailer and its accessories.

Right Scroll Wheel Trailer Brake: Enabling this allows you to tilt the right scroll wheel to the right, which will trigger the trailer brake. This disables the follow distance control for TACC.

Trailer Alarm: Cybertruck can extend its coverage of Sentry Mode to the trailer hitch - if the trailer is disconnected, the alarm will sound, and you will be notified.

Profile-Derived Improvements

Tesla’s new Trailer Profiles allow your vehicle to make better predictions of its energy usage. This will also let your in-vehicle navigation adapt to charging stations, better predicting when you need to stop and for how long. Plus, while you have tow mode engaged, your vehicle will automatically prioritize trailer-friendly Superchargers.

For anyone who tows, this will greatly help when towing, especially over longer drives. As your vehicle adjusts to your trailer’s energy usage the accuracy of the feature will continue to improve.

Tesla FSD Vehicles To Receive Latest Features With Update 2025.2.8

Tesla has now merged the latest FSD versions with the newest Tesla production features. This has several impacts on users with and without FSD, including giving FSD vehicles some of the latest Tesla features. The new software update is 2025.2.8 and it’s rolling out now in several countries.

FSD Vehicles Get Latest Features

For the first time, Tesla’s FSD is based on the 2025 branch, bringing the latest features to vehicles with FSD.

The highlight features of update 2025.2 include Hands-Free Trunk and Frunk Support for Android, the Rear Cross-Traffic Chime and it finally activates the in-vehicle radar in Model Y vehicles. In North America, vehicles also gain access to Third-Party Charger Preconditioning, while the Cybertruck gets Trailer Profiles support and some much-needed improvements to its wiper.

As for FSD, this update still includes FSD 12.6.4 for HW3 vehicles and V13.2.8 for HW4 cars, so there aren’t any updates there except for potential bug fixes.

New Base FSD Version?

While the latest FSD version is now available on update 2025.2, it’s not immediately clear whether this replaces FSD V12.5.4.2 as the new base FSD version that Tesla will include in all future updates.

Tesla has the ability to include different FSD releases with the same software update, so we’ll have to wait and see if this version continues to roll out to non-FSD vehicles.

Subscribe and Get the Latest FSD

Since Tesla doesn’t allow vehicles to roll back software update versions, users who were already on one of Tesla’s 2025.2 updates would be stuck with receiving FSD 12.5.4.2. However, anyone who subscribes to FSD will now be eligible to receive the latest FSD version.

FSD versions often lag behind in non-FSD Tesla features, so it’s always exciting to see an update go out that catches everyone up. Furthermore, if Tesla makes FSD V12.6 and V13.2 the new base versions that are included in all Tesla updates, that will be a huge win for everyone as these latest versions perform much better for most users.

Tesla’s next major update may be their Spring Update, which last year included a ton of new features, so there is a lot to look forward to!

Tesla Awaits Regulatory Green Light for FSD in Europe

March 1, 2025

Tesla recently launched FSD in China, making it the first region outside North America to receive the feature via a software update. This marks a major milestone for Tesla, which has been working diligently to gain regulatory approval outside of North America.

Both China and Europe were key targets on Tesla’s Autonomy Roadmap, with the company aiming to roll out FSD in these regions by Q1 2025—pending regulatory approval.

Regulatory Issues

Elon Musk recently confirmed on X that FSD is ready for Europe—Tesla is just waiting on regulatory approval. However, securing approval could be challenging, as the process is overseen by the United Nations Economic Commission for Europe (UNECE), which sets regulations for the entire EU.

While the UNECE has fast-tracked some advancements—such as adaptive and matrix high-beams (soon available in the U.S.), its approach to autonomy has been far more cautious. The commission has consistently slowed the deployment of self-driving technology and even reduced the capabilities of Autopilot.

Adding to the challenge, the UNECE body responsible for vehicle autonomy meets infrequently, sometimes with months between sessions. The next meeting is scheduled for March 4, but autonomy is not yet on the agenda, meaning approval could still be a long way off.

We are waiting for regulatory approval - Musk

Regulation 157

UNECE Regulation 157 governs “Automated Lane Keeping Systems” (ALKS), similar to Autopilot or lane-keeping cruise control in other vehicles. This regulation imposes strict limits, including speed restrictions and requiring driver confirmation for every autonomous decision.

While approving a lane change with a tap on the screen or steering wheel might seem minor, imagine having to do so for every FSD action—speed adjustments, turns, stops, starts, and more.

Additionally, Regulation 157 only permits autonomy in areas where pedestrian traffic is physically separated from vehicles. This means that many highways without clear barriers would be off-limits for autonomous driving.

Hope on the Horizon

There’s still hope—if the UNECE amends Regulation 157, over 50 nations, including the EU and Japan, could open the door for FSD.

A step in the right direction came with the 2024 adoption of UN Regulation 171, which expanded the framework for driver-assist systems that don’t fully take over control—such as FSD (Supervised).

While regulatory changes take time, the momentum is building. As technology advances rapidly, it’s only a matter of time before the rules catch up.
