Over the past few years Tesla has released a major version of their car's software every year (v10 update, v9 update). This year we have been anticipating version 11. Elon Musk has teased it several times and has said that it will include features we've been wanting and features we didn't know we wanted.
The past few Tesla releases have been unusual and have only contained minor changes and bug fixes as Tesla appears to be keeping features in v11 hidden.
The anticipation has been building and now it looks like v11 has been leaked on a redesigned Model S test vehicle.
A major focus of this release appears to be personalization. When examining the UI, a lot of the elements appear to be customizable, where a user could possibly choose which icons or apps they'd like to show up. Elon Musk has previously tweeted that Tesla would allow multiple layouts in the future. He could have been hinting at these features in v11.
In the first image we can see this new tile-like interface, where you will presumingly be able to select which tiles you'd like to appear. For example, you may choose to have Music, Car Visualizations, Maps, Calendar, Energy Graph and many others. It'll be interesting to see how many choices Tesla really offers here and how they adapt this to other vehicles.
When we take a closer look at the bottom bar which normally houses a consistent car navigation and is the main way to get to climate controls, seat heaters and other apps, it looks like this will also become customizable. From the image we can see that the nav no longer takes up the full width of the screen and that in this image the seat heaters are right next to one another, which is very different from what Tesla has offered in the past.
There are now many apps and features in Tesla vehicles where some of them now require multiple taps to get to, and making this navigation customizable makes a lot of sense. For example if a user relies on the Phone app heavily, they will now be able to access it with one-tap instead of two. Like-wise, if you don't live in a cold climate, it's almost silly to have seat heaters and the rear window defroster take up multiple spaces in this prime real estate area.
We have recently seen buttons removed or moved around in recent updates. One such example is that the Voice Commands button has been removed and is currently only accessible through the buttons on the steering wheel, leaving the passenger without a way to use voice commands. We expect this button to return with v11.
The former top strip which contained car information and quick actions such as the time, Bluetooth, HomeLink and other functions have been moved and appear as a vertical strip on the left side of the screen.
It looks like right beneath this, we will see another big feature which appears to be a "Quick Menu," which will allow you to access the car's most often used features. Upon tapping it you will be presented with quick-function buttons such as lock car, open frunk, open glove box, display brightness, mirror and steering wheel adjustments and others.
Some of these features were fairly accessible before, but others required digging through the Car Controls menu, so this should make changing some settings much quicker. There doesn't appear to be a clear indication in this menu, but given the same square tile-like buttons, we would also expect these tiles to be customizable.
We also get a quick-peek at some of the other car menus. It looks like this particular version of the car (remember this is a refreshed Model S, but unclear whether it's Plaid or not), will also feature a "Drag Strip Mode." It's not clear which models this will apply to but it appears to be a new launch control system.
Continuing looking at this menu, a few other things stick out. We can see there is an option for "Smart Shift," which will allow the car to shift into drive or reverse for you. We knew this feature would be included in the refreshed Model S / X, but it's certainly possible that Tesla will bring this feature to all existing AP 2+ vehicles. We wouldn't necessarily expect it, but it's certainly possible. We also recently discovered how this feature will work.
We also see that there is a new option to turn on/off "Media on Drive," which gives you control whether you'd like the media player to automatically open when you put the car into drive.
The menu on the left looks very familiar with some minor changes. We no longer have the Quick Settings option at the top, which the Quick Menu from the home screen seems to have replaced. We also see a new "Trips," tab, which could be for more precise navigation settings, and possibly allowing for multi-stop destinations (way-points), which Elon Musk said was coming last September.
There are sure to be many more features included in this huge v11 release, but these are the major features we can see looking through these few images.
Some of these features will be slightly different on other vehicles as Tesla has to adapt them to work on a vertical screen for previous Model S / X vehicles and also make adjustments for the Model 3 / Y which need to include car visualizations on the main display.
We are all super excited for this highly anticipated release which appears to focus heavily on personalization.
Tesla vehicles are equipped with two main computer systems: the MCU (Media Control Unit), which is responsible for entertainment and display functions, and the Autopilot/FSD Unit, often referred to as the FSD Computer.
Both of these systems have evolved over the years, and they’re commonly referred to by their generation. For example, MCU 2 refers to the second generation of the Media Control Unit. Similarly, the FSD computer is identified by its generation, often called Hardware 3 or Hardware 4, when referring to the third and fourth-generation hardware. More recently, Tesla has started referring to the FSD Computer as AI3 and AI4, but you’ll still hear the older terms used interchangeably.
These two systems are separate and they’re not upgraded at the same time, meaning it’s possible to have a vehicle with MCU 2 and FSD Hardware 3 or MCU 3 with Hardware 3. Some vehicles even feature MCU 1 alongside Hardware 3.
The MCU is not involved with Autopilot or FSD functions—it’s purely for infotainment and in-vehicle features such as vehicle visualization, gaming, maps, and entertainment. It doesn’t impact the capabilities or limitations of Tesla’s autonomous driving systems.
MCU 1 - NVIDIA Tegra 3
MCU 1 was the first media control unit to be introduced in Tesla vehicles, starting back in 2012. This system was used in the Model S and Model X until about April 2018, when Tesla began transitioning to MCU 2.
By the time the Model 3 launched in late 2017, it already included MCU 2. To keep legacy vehicles up to date, Tesla offers an infotainment retrofit that upgrades MCU 1 to MCU 2, which helps make the infotainment unit much more responsive and adds a variety of newer features. Tesla continues to support vehicles with MCU 1, although upgrades are much further apart. In 2024, Tesla added Automatic Emergency Braking (AEB) improvements to vehicles with MCU 1 and even support for FSD V12.3.6 (FSD HW3 required).
Period Offered: 2012 through April 2018
Upgrade: Available as a paid upgrade for Model S and Model X vehicles to go from MCU 1 to MCU 2.
MCU 2 - Intel Atom
The launch of the Model 3 introduced MCU 2, which ran on Intel’s Atom mobile processor. While the Intel Atom was capable at the time, it’s now considered outdated compared to modern standards. As Tesla continues to roll out new features, the limitations of the Atom processor have become more apparent.
There is a notable list of features that are unavailable to vehicles with MCU 2. Although Tesla has optimized software to improve compatibility, not all features have been made accessible to these vehicles.
Period Offered: MCU 2 was offered in 2017 (Model 3) through 2022 (availability differs based on region and model).
Upgrade: As of now, Tesla has not offered an upgrade path or retrofit to transition from MCU 2 to MCU 3, and they’re unlikely to do so.
MCU 3 - AMD Ryzen
In December 2021, Tesla began shipping vehicles with MCU 3, powered by AMD’s Ryzen processor. The first vehicles to feature MCU 3 were the refreshed Model S and Model X, which debuted in 2021. Shortly after, Model 3s and Model Ys were also equipped with MCU 3, and today, all Tesla vehicles, including the Cybertruck, come standard with MCU 3.
This MCU is now the most widely used on the road and is Tesla’s most advanced infotainment processor. It supports impressive 3D visualizations, allows improved gaming on the center touchscreen (and rear screens in equipped vehicles), and offers a host of other capabilities. MCU 3 is also the most feature-complete version, with new features being designed for it first and then backported to MCU 2 or MCU 1 when possible.
Period Offered: The first MCU 3 vehicles were released in December 2021 and is current through today.
Upgrade: MCU 3 is the most current infotainment unit that Tesla offers.
Features Missing on MCU 2 (Intel Atom)
High-fidelity park assist is limited to vehicles with MCU 3
Not a Tesla App
While Tesla does its best to continue to support MCU 2, there is a growing difference between the features available on a vehicle with an Intel Atom infotainment unit and one with the AMD Ryzen processor.

In the interface, you’ll find details about whether your vehicle is equipped with an Intel Atom (MCU 2) or AMD Ryzen processor (MCU 3).
MCU 4?
It’s been more than three years since Tesla introduced the AMD Ryzen-powered MCU. Despite advancements, including the transition from FSD Hardware 3 to AI4—and eventually AI5—there’s been no indication of an MCU 4 on the horizon.
The Ryzen processor’s impressive capabilities make it a solid choice for infotainment, and it’s well-suited to serve until there’s another big leap in CPU performance.
While Tesla will upgrade to MCU 4 at some point, it doesn’t seem imminent. Some may argue that Tesla transitioned to MCU 3 too late, leaving vehicles just a few years old feeling outdated. It’s possible Tesla might choose to introduce MCU 4 ahead of the need for more processing power, ensuring that older vehicles can continue to benefit from new software features in the future.
Following the surprising return of the turn signal stalk on the refreshed Model Y, reliable Tesla source Chris Zheng has indicated that the Model 3 will also be receiving a turn stalk. While it initially seems surprising, Tesla mentioned that after receiving lots of customer feedback, there is a lot of demand for the return of the stalk.
For those who appreciate the newer turn signal buttons on vehicles like the Cybertruck, this might come as a surprise. However, the Model 3 and Model Y are designed for the average driver transitioning from a traditional vehicle, making the removal of the turn signal stalk an unexpected and potentially disappointing change.
Turn Stalk
In a conversation during the latest episode of Jay Leno’s Garage, Tesla’s VP of Vehicle Engineering, Lars Moravy, mentioned that Tesla works to remove superfluous parts. In this case, they removed one part too many - and are now bringing back the turn signal stalk.
The updated stalk on the refreshed Model Y is a simplified version of the current Model Y stalk. It doesn’t include multi-stage turn signals (short three flashes versus staying), buttons, or other features. Pure and simple - it is utilized for signaling left and right. The rest of the functions of a traditional stalk remain either on the wheel or on the screen.
Lack of Right ‘Shifter’ Stalk
Tesla has no intent to bring back the right stalk, which is traditionally used to shift the vehicle from Drive to Reverse and Park in Teslas. It’s also used to activate Autopilot. The shifting functionality will remain on-screen or available via the backup by tapping the buttons on the ceiling near the hazards button. Shifting via the dash is intuitive and convenient once you get used to it - and with AutoShift hopefully coming out of Beta sometime soon, this could get even better.
Autopilot activation will remain with a button on the steering wheel. While a vehicle with a single stalk may look a little odd at first, Lars mentioned that Tesla didn’t receive many complaints about shifting or Autopilot use.
Retrofit
Not a Tesla App
We haven’t heard anything about retrofitting the 2024+ Model 3s with the turn signal stalk at this point. However, we imagine this may be a possibility in the future.
However, we can recommend using the wireless Enhauto’s S3XY Stalks if you want to bring a single or dual stalks back to your refreshed Model 3 and don’t want to wait for an official retrofit to arrive. They’re easy to install, well-designed, and reliable.
Other Models
The big question now is: will Tesla bring back the turn signal stalk for its other models? It’s possible, but we doubt it. The Model S and Model X, especially with the Yoke, feel more natural without a stalk, and the button-based signals suit their design. While a stalk might occasionally be useful—like signaling in and out of a roundabout—any future refresh of the S or X would likely include steer-by-wire instead.
On the Cybertruck, the absence of a stalk goes unnoticed, thanks to steer-by-wire, as the squircle steering wheel is never in an awkward position. After thousands of kilometers of daily driving, including plenty of roundabouts, the author can confidently say the signal stalk isn’t missed at all. In fact, the turn signal buttons feel more intuitive, given how the Cybertruck handles.
That said, could Tesla offer signal stalks as an option for those who prefer them? It’s not out of the question. We’ll keep you updated, but in the meantime, let us know—do you prefer turn signal buttons or a traditional stalk?
