Tesla’s Updates FSD Roadmap: Talks FSD V13 and End-to-End Highway

October 31, 2024

Last month Tesla shared a roadmap with its progress on FSD and its goals for the coming months. Since we’re coming to the end of October and Tesla had yet to release the two items listed under October, we asked Tesla if they could provide an updated roadmap to help keep everyone’s expectations in line.

We’re not sure whether Tesla saw our message or already had plans to provide an updated roadmap, but today Tesla published an update to its initial roadmap.

Instead of focusing on timelines, Tesla has now simply published what their AI team is working on and what customers could expect next.

Tesla’s Original Timeline

The roadmap Tesla provided in early September focused on FSD improvements, releasing Actually Smart Summon, FSD on Cybertruck, FSD v13, and the expansion of FSD outside of North America.

This was Tesla’s initial roadmap which was provided on September 5th.

September 2024

v12.5.2 with ~3x improved miles between necessary interventions
v12.5.2 on AI3 computer (unified models for AI3 and AI4)
Actually Smart Summon
Cybertruck Autopark
Eye-tracking with sunglasses
End-to-End network on highway
Cybertruck FSD

October 2024

Unpark, Park and Reverse in FSD
v13 with ~6x improved miles between necessary interventions

Q1 2025

FSD in Europe (pending regulatory approval)
FSD in China (pending regulatory approval)

Elon Musk also replied to Tesla’s post, saying that, hopefully, right-hand drive markets will also get FSD in late Q1 or early Q2.

Goals Tesla Met

While we’re only at the end of October, Tesla managed to check off their September goals with a perfect score, nailing all of their goals such as eye-tracking with sunglasses, FSD on the Cybertruck and releasing Actually Smart Summon in the United States and Canada.

They also released the unified FSD model for HW3 and AI4, although it seems like the good news may stop there for HW3 owners. At least Tesla has recently said HW3 owners will get a free upgrade to more capable hardware if Tesla isn’t able to achieve unsupervised FSD on those vehicles.

Goals Tesla Is Still Working On

Although the company met its September milestones, the October goals have been delayed. Initially targeting the release of unpark, park, and reverse features and FSD v13 for October, Tesla now plans to integrate these features with FSD v13 in November.

The delay isn’t surprising given the ambitious goals, but we’re thrilled to see that Tesla is keeping the communication lines open.

The goals Tesla set to release FSD outside of North America are still to be determined, but we presume they may shift slightly due to the delay of FSD v13.

What’s Coming

While Tesla avoided dates and timelines for their upcoming features, they actually provided a lot more detail on what they’re working on and what we can expect in FSD v13. Unfortunately for HW3 owners, most of these improvements appear to be destined for Hardware 4 (AI4).

Complete Rollout of End-to-End

Tesla’s first item on its updated list is to complete the rollout of its end-to-end highway stack. Tesla’s current highway stack is based on FSD v11 and doesn’t feature end-to-end AI, meaning that AI is only used for input and not to control the vehicle. End-to-end AI essentially has AI managing everything in the vehicle, from detecting objects and lane markers to the steering and brake pedals.

Tesla started including end-to-end for highway driving in FSD v12.5.5 for the Cybertruck and then opened it up to other AI4 vehicles with FSD 12.5.6. The latest public FSD version is FSD 12.5.6.1, but it’s only available for AI4 vehicles.

The majority of vehicles with FSD are still on version 12.5.4, which doesn’t include the new highway stack. Tesla aims to release the updated highway stack to all AI4 vehicles next week, which will also include improvements to stop smoothness and improved bad weather notifications.

Actually Smart Summon

While Actually Smart Summon was released in September in North America, most of the world is still waiting. Tesla now says that A.S.S. will be available in other regions but didn’t provide a timeline. Users who bought or subscribe to Enhanced Autopilot or FSD in Europe should expect to receive this feature as part of Tesla’s normal feature releases instead of being a part of a special FSD build. It’s possible this could come in Tesla’s next major update, possibly 2024.44.

It’s not clear whether Tesla’s list was in any sort of order, but if it is, we could expect Actually Smart Summon sooner rather than later.

Improved FSD for HW3

Tesla’s updated list was largely focused on FSD for AI4, but HW3 did get mentioned in one bullet point item. Tesla says that HW3 should receive improved FSD v12.5.x models for city driving. Unfortunately, this almost sounds like bad news. AI4 mentions in the roadmap talk about FSD v13 and end-to-end highway support, while HW3 specifically states improved “city-driving,” possibly saying that end-to-end highway driving is not coming to HW3 vehicles soon.

Given that a new version of FSD v12.5.4.2 just started rolling out for HW3 vehicles, it looks like it may be a while before HW3 owners have access to the new highway stack. Earlier this month, Musk said that HW3 owners should receive an update that will increase FSD’s smoothness, so it seems like this is what Tesla is referring to in their roadmap.

FSD V13

The rest of Tesla’s post was dedicated to FSD v13. Tesla provided a lot of specifics such as FSD v13 unlocking the full resolution of Tesla’s HW4 cameras. The computer will now process full-resolution video at 36 FPS instead of using lower frames per second or scaling the video down.

FSD v13 will also increase the AI model by three times and data by 4.2 times. Tesla expects this to provide better collision avoidance, improved traffic controls and navigation.

FSD Unsupervised Feature Complete

Tesla’s VP of AI, Ashok Elluswamy, is just as excited about v13. He reposted Telsa’s post and said that a lot of work is going into the FSD v13 release and that Tesla expects v13 to make FSD Unsupervised feature complete. This is far from saying that FSD v13 will achieve autonomy, but simply that all the pieces of the puzzle are now in place with v13. The car will be able to navigate from a garage to its parking spot at a destination without any human input. Each of these pieces will likely still need to be refined over time to achieve unsupervised FSD.

Release Date for FSD V13

Tesla is targeting the release of FSD v13 to employees by the end of this week. Tesla expects the update to go through several iterations before it’s released to customers in FSD v13.3. Tesla says that the target launch for a public version of FSD v13.3 is around Thanksgiving for AI4 vehicles.

FSD Arrival Options

In addition to FSD v13 including the ability to “unpark,” reverse and park itself, Tesla will also add various options for when the vehicle arrives at its destination. Users will be able to choose from simply pulling over, parking in a parking spot or driveway or even a garage.

We believe that “unpark” in this statement refers to the ability for the user to engage Autopilot while the vehicle is still parked. The vehicle will automatically shift from Park to Drive and drive or reverse out of its parking spot before proceeding to its destination.

Detecting Emergency Vehicles

One other item Tesla pointed out in their roadmap is that FSD v13 will process audio inputs to better handle emergency vehicles. FSD now appears to rely only on detecting emergency vehicles visually, but with FSD v13, Teslas will be able to detect them audibly as well. Unfortunately, all Teslas only have microphones inside the cabin, which are currently used for phone calls and voice commands, but Tesla will soon continuously process the audio to detect emergency vehicles and potentially other things.

Outlook

Tesla has already integrated some v13 improvements and reports a 4x increase in miles between necessary interventions compared to v12.5.4. It’s clear that Tesla’s focus is on AI4 and reaching its goal of Unsupervised FSD. They appear very focused on this goal and will do whatever it takes to get there. Right now, that means focusing on AI4, but if at any point they run out of compute power needed there, they could shift to AI5, but that’s not expected to happen any time soon.

AI5, which is included in the Cybercab, isn’t expected to be released until the end of the year. We expect Tesla to continue marching toward achieving autonomy, regardless of the power required. Once they can figure out FSD, they can work backwards to get it working on older hardware.

Tesla Intel Atom (MCU 2) and AMD Ryzen (MCU 3): Feature Differences and How to Tell What You Have

February 18, 2025

By Karan Singh

DirtyTesla

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.

Feature	MCU 2	MCU 3
Games / Arcade	⚠️ Limited Games*	✅ Additional Games**
Parked View	⚠️ Split screen visualization with vehicle on left and map on right	✅ Full-screen Parked Viz - Shadows, Sun Reflections, Shadows
Vehicle Visualizations	⚠️ Some limitations, such as non-transparent glass	✅ Improved visualizations
Full-Screen FSD Visualization	⚠️ Only Available in North America	✅ Available in All Regions
Zoom Meetings	❌ Not Available	✅ Available
High Fidelity Park Assist	⚠️ Top-Down Visualization Only	✅ Full 3D Visualization
Autopark Visualizations (video)	⚠️ Top-Down Visualization Only	✅ 3D Visualization
Improved UI for Display Modules - Media, Next Turn, Trip Planner	⚠️ Solid Color/Semi-Transparent	✅ Transparency + Background Blur for Display Modules

*Many recent game additions are available to MCU 3 only, including the ever-popular Vampire Survivors and Castle Doombad. Only certain Model S and Model X vehicles include a GPU and the ability to play games on Steam.

**Atari Games were removed from MCU 3 vehicles due to Emulator Licensing issues.

How to Tell - Intel or AMD

Identifying which MCU your vehicle has is straightforward. Simply go to Vehicle Options > Software > Additional Vehicle Information.

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.

Tesla Expected to Add Turn Signal Stalk Back to Model 3

February 18, 2025

By Karan Singh

Not a Tesla App

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?
