First Look at Tesla FSD V12.6 and How It Compares to FSD V13

Not a Tesla App

A couple of weeks ago, Ashok Elluswamy, Tesla’s VP of AI, announced that Tesla would finally roll out an FSD update for vehicles with Hardware 3. Earlier this week, on December 30th, Tesla did just that and started a public rollout of FSD V12.6.

Since the initial rollout, the update has gone out in several other waves, but they’ve been extremely small. Thanks to several users, we know have our first look at FSD V12.6 and how it compares to the previous FSD version and to the latest version for Hardware 4 vehicles — FSD V13.2.2.1.

How FSD V12.6 Compares to 12.5.4.2

Vehicles receiving the FSD V12.6 update are coming from Tesla’s Holiday update, version 2024.44.25.2, which includes FSD V12.5.4.2.

While FSD V12.5 was a big step up from FSD V12.3.6 for most users, it did include its share of issues. The big two have been lane selection and behavior at traffic lights.

While the release notes for FSD V12.6 highlight features such as End-to-End on Highway, Improved City Streets Behavior, and Smoother and More Accurate Tracking, FSD V12.6 is noticeably smoother and more capable. It now handles turns and scenarios that it struggled with or simply couldn’t perform on FSD V12.5.

How it Compares to FSD V13

One of the key features of FSD V12.6 is a redesigned controller for smoother and more accurate tracking. This feature actually comes from FSD V13, so users should think of FSD 12.6 as a hybrid between FSD V12 and FSD V13. In fact, it seems like Tesla considered calling this version V13, but more on this later.

The controller referenced in the release notes is responsible for tracking objects around the vehicle. The vehicle can only drive as well as it can see, so the improved tracking accuracy directly improves FSD decision-making, leading to smoother driving. This is very evident in FSD V12.6, which now delivers a level of smoothness comparable to what users are experiencing in FSD V13.

Thanks to Rhys Samson, who has both FSD V12.6 and FSD 13.2, they directly compare the two versions and say that FSD V12.6 now operates as smoothly and confidently as his Cybertruck on FSD V13.2.

In their eyes, FSD 12.6 has done a lot to reduce, if not eliminate, the anxiety of not having AI4/HW4 in their Model S. This may change as AI4 vehicles continue to receive improvements while HW3 vehicles are expected to lag in FSD updates, but FSD V12.6 is a big step forward and could have arguably been called FSD V13.

Which Vehicles are Receiving V12.6

Right now, FSD V12.6 is only rolling out to Model S and Model X vehicles with Hardware 3. So far this has only been “refreshed” models, so it doesn’t include Model S/X cars prior to 2021. When the update was released on December 30th, Ashok Elluswamy stated that the update would be available for “other platforms,” presumably the Model 3 and Model Y, within a week. This puts us at around January 6th for other models. Ashok’s timelines have been extremely accurate and we believe Tesla will deliver this update sometime next week.

The Model 3 and Model Y are expected to be supported, but it’s not clear whether it’ll also include legacy Model S/X vehicles as well.

We expect this release to eventually become available for everyone soon, the only question would be whether it’d become available for legacy S/X vehicles with MCU 1. While the upgrade to MCU 2 isn’t cheap, any owners with an MCU 1 vehicle and HW3 would receive a much more capable vehicle by upgrading to the newer infotainment unit.

What About FSD V13 for HW3?

Rhys Samson

While we expected Tesla to release an FSD update for HW3 vehicles with the new end-to-end highway stack, FSD V13 was more of a wildcard. Would Tesla wait to upgrade HW3 vehicles with newer hardware or spend the time creating a smaller V13 model for HW3 vehicles?

Due to a small bug, it looks like we may have some insight into this question. Users who have installed FSD V12.6 will notice that while the release notes and the vehicle will call update 2024.45.25.10 FSD V12.6, the version shown in the app is actually quite different.

At the bottom of the main screen in the Tesla app, Tesla will show several bits of information, including your vehicle’s software version and the FSD version. While the vehicle software is correctly labeled as 2024.45.25.10, the FSD version actually mentions an unreleased FSD version — v13.2.3.

While this could simply be a bug or a typo, it could also be an indication that Tesla was considering calling this release FSD V13.2.3 and that it may have been a last-minute decision. While this may not mean much, it could be a sign that is already thinking about or developing FSD V13 for HW3 vehicles.

Keep in mind that many features for FSD V13 take advantage of the more powerful hardware, such as larger AI models and improved video feeds. However, other features could potentially be carried over to HW3.

Roll Out

While FSD V12.6 is still only available for the Model S and Model X, it continues to go out in increasingly larger waves. The last wave occurred overnight, and there’s a possibility of us seeing more today. Given the continued waves, it looks like everything is on track for a release to other models this weekend or early next week.

You can keep an eye out on our statistics page to track additional roll outs, and we’ll be sure to cover the release when it becomes available to more vehicles.

Want to See the New Tesla Model Y? Here's Where It’s on Display

Not a Tesla App

Tesla’s refreshed Model Y has started hitting display and Tesla showrooms across North America and Europe, where you can now get up close and personal with the new Model Y and all of its improvements, including the smallest of details.

The refreshed Model Y surprised all of us by sporting its own unique look instead of just being a stretched-out Model 3. While it’s available to order now through the Launch Edition, which includes FSD and Acceleration Boost, deliveries won’t start for another couple of months.

The new front light bar and rear indirect lights make the vehicle unique and worth checking out. There are plenty of new items to check out in the updated interior as well, including new door panels, powered rear seats, and more.

Here’s where you can check out the new Model Y in North America and Europe:

North America

In North America, the updated Model Y can be seen in 19 showrooms across the United States and Canada. The photo below shows the 17 locations in the U.S. and two in Canada. We expect this list to grow as Tesla produces more vehicles and we get closer to the official launch.

New Model Y Displays in North America

Not a Tesla App

Europe

In Europe, the Model Y is already on permanent display at two locations - the Mall of Berlin in Germany, and at Tesla’s Amsterdam Europe Headquarters - both publically accessible. If you’re in the area, definitely drop by and take a look.

Tesla is also holding special events throughout Europe where they’ll be showing the new Model Y through select dates. place to check if you’re far away from the ones above is on Tesla’s Events List.

We recommend checking the page out to confirm any dates, as Tesla will be rotating the locations until each showroom receives its permanent display vehicles.

Tesla will also be visiting major auto shows, including the Toronto and New York International Auto Shows with the new Model Y - so keep an eye out for those events as well.

Tesla's Holiday Update: The 15 Undocumented Features

Not a Tesla App

While Tesla’s exciting holiday update is now behind us, it left us with amazing new features, such as weather radar, Apple Watch support, mobile Dashcam viewer, SiriusXM, and so many other great features that some of us now use every day.

However, it doesn’t end there. Tesla always includes other smaller changes that don’t make it into the release notes, and the holiday update was a big one in terms of undocumented changes.

We’ll go through all the new features that are now available in your vehicle that Tesla didn’t show in their release notes.

Precipitation Map

Not a Tesla App

While this feature did make it to the release notes, some users may still not be aware that the Precipitation Map (weather radar) is now available on all Teslas with the Intel infotainment unit (except for legacy Model S/X). This feature was requested so long ago that, honestly, we didn’t think it’d ever be released. All Model 3, Model Y and 2021+ Model S and X vehicles now have access to the weather radar map overlay.

Fart on Sit

Not a Tesla App

For the Emissions Testing Mode easter egg, you can now have your vehicle fart when someone sits down in their seat.

The sound will come from the direction of their seat. For example, a fart sound will sound from the front-right speaker when someone sits in the front passenger seat. It will play the sound selected in the fart selection box, or play a random fart if you choose "I'm so random."

This option defaults to off after every drive.

Voice Assistant

Not a Tesla App

You can now say 'Hi' or 'Hello' to your vehicle through the voice command prompt, and the vehicle will respond with "Hello!"

This is the first sign of Tesla adding a smart voice assistant to the vehicle, which is expected to be powered by Grok.

Voice Command Changes

Not a Tesla App

If you use Tesla's voice commands, there are a few changes. When you press the voice command button on the steering wheel, you may now not get audible feedback that the button has been pressed. This will depend on whether there’s music playing or other circumstances.

When sending a text message through a voice command, you may now have to press the steering wheel button again to start dictation after choosing a recipient. It’s not clear what’s causing this change, as sometimes it goes straight into dictation mode, while other times it ask you to press the button to start dictation.

Equalizer

Not a Tesla App

You can now reset the equalizer settings with the touch of a button by tapping the new circular arrow to the right of the equalizer. This will bring all settings back down to 0.

Performance Improvements

Not a Tesla App

Intel users are seeing performance improvements while using the Tesla interface, especially in more demanding areas like Tesla Theater. Videos on YouTube now stutter less and Tesla Theater can be minimized more smoothly than before.

The media controls can now control YouTube videos and other web video content as well, even after the vehicle is put into drive.

Service Mode Updates

Not a Tesla App

Several screens in Service Mode have been updated to show larger visualizations, such as the Airbags and Seats menu.

Tesla has also introduced several new visualizations to vehicles with the Intel infotainment unit, that were previously only available on AMD-based vehicles. Some of these includes Coolant and HVAC options.

The only new feature in Service Mode is for the Cybertruck under Service Mode Plus, which includes:

Connector Reference (Service Mode Plus): A new Connector Reference panel is available to help find connectors and highlight harnesses on the vehicle. Rotate the 3D model to explore or type in the search bar to find a specific connector.

Rearranged Menus

Not a Tesla App

With the addition of the Seats menu to settings, Tesla has now rearranged the menu options so that the more used options are now more easily accessible.

The Software menu has been moved up, while other options like Navigation and Trips have been moved down to be close to WiFi, Bluetooth and Upgrades.

Selected Custom Lock Sound

Not a Tesla App

The currently selected custom lock sound is now shown underneath the Lock Confirmation Sound option in the Controls > Locks menu.

Ambient Lighting Easter Eggs

Not a Tesla App

The Rainbow Road and Santa Mode easter eggs have been updated on vehicles that include the ambient lighting feature.

There are new options in these easter eggs that let you enable or disable the ambient lighting while the easter egg is active.

If enabled, the light strips will cycle through colors of the rainbow when the Rainbow Road easter egg is enabled. For Santa Mode, the interior lights will cycle between red, green and white.

Updated Energy App

Not a Tesla App

The Consumption tab in the Energy app has been updated with several changes, including:

• The last 200 miles are now shown, instead of a user-selectable, 5, 15 or 30 miles.

• Instant Range / Average Range has been removed to simplify the interface.

• The average range as moved to the top left and now shows the offset from the vehicle's EPA-rated Wh/mi

• Total energy consumption is now displayed at the bottom left.

• The colors now have different meanings. Before this update, yellow meant the vehicle was using energy, while green meant the vehicle was generating energy through Regenerative Braking. However, now, yellow means that the vehicle consumed more than the EPA average, and green means that the vehicle consumed less than the EPA average and doesn’t necessarily mean it generated energy.

Toll Roads

Not a Tesla App

When navigating to a destination, the alternative routes menu that is displayed when you first enter a destination will now show you which routes include tolls by displaying a dollar sign icon next to the travel time.

Limiting Explicit Content

Not a Tesla App

The Exlicit Content toggle under Audio Settings now applies to YouTube Music as well. This now supports LiveOne, Apple Music, Apple Podcasts, and TIDAL.

Charging Icons

Not a Tesla App

Tesla has redesigned the charging pins that appear on the map. Supercharger and third-party charger pins are now oval-shaped instead of circular.

Instead of just having the number of charging stalls available, Tesla has added the charging icon to make it more obvious these are charging stations.

Adjust Dashcam Viewer Speed

Not a Tesla App

You can now adjust the Dashcam Viewer's playback speed. Users can pick from 0.5x, 1x or 2x playback speeds by tapping the playback speed button.

Tire Pressure Indicator

Not a Tesla App

Tapping the tire pressure indicator will now open the tire pressure card on the left side of the screen instead of opening the Service menu under Controls > Service.

If you ever spot a change that isn’t listed in Tesla’s release notes, we’d love to hear about it!
