Tesla’s Q4 earnings call is coming up, and just like Tesla has done in the past, they’ll be answering popular investor questions during their Q&A session.
The earnings call itself opens up at 5:30 PM EST on January 29, 2025 - and Travis Axelrod, Head of Investor Relations at Tesla, will be heading the event, as usual. Tesla Investor Relations will livestream the event, and we’ll have links available for you once they’re posted.
Q4 2024 Top Questions
Tesla is once again accepting questions for their Q&A portion of the call through Say Technologies. While the Say Q&A question voting isn’t over, some of the most popular questions will likely stick at this point. The current batch of questions is interesting and should provide additional clarity on what Tesla hopes to accomplish in 2025.
Here are the current top 10 questions:
Is unsupervised FSD still planned to be released in Texas and California this year? What hurdles must be overcome to make this happen?
Is Optimus now mostly design locked for 2025 production?
When will Tesla start selling Optimus and price?
Elon has said publicly that long-term shareholders of Tesla will have the ability to invest in his other companies. Could you provide some clarity/color as to what that looks like? Brokerage firms use FIFO, so anyone who trades won’t have the true length of time as an investor.
Are there any discussions with other auto companies about licensing FSD?
Is it expected that Tesla will need to upgrade HW3 vehicles and if so, what is the timeline and expected impact to Tesla's CapEx?
What is the status on mass production of the Tesla Semi? How do you project it will affect revenue at scale?
Is there a new affordable Tesla model coming soon?
What technical breakthroughs will define "v14" of FSD, given then v13 is photon-to-control?
Is the Roadster still launching this year?
Note: We’ve made some grammatical corrections to the above questions to improve readability.
Interesting Questions
There are several other interesting questions that aren’t in the top 10, but making it into the top 10 isn’t a guarantee that Tesla will answer the question during their investor call, but they’ll at least be aware of what’s on investors’ minds.
Here are some of the more interesting questions investors have submitted:
Can you please tie purchased FSD to our owner accounts vs. locked to the car? This will help us enjoy it in any Tesla we drive/buy and reward us for hanging in so long, some of us since 2017.
Full voice control of the car, via Grok, will be a huge improvement. Can you elaborate on that functionality and when we will see it in cars?
When are we going to get the extended battery pack for the Cybertruck, and what is the range?
When will we see additional states added to Tesla insurance? Can you provide any additional info about the projects status?
How will Tesla manage having a part-time CEO, with Elon being busy with DOGE, SpaceX, X and others? Is a strong COO, ala Gwynn Shotwell, being considered?
Can you tell us some of the safety statistics for FSD v13.2 so far? How close is Tesla to achieving 1000 miles per intervention? 10,000 miles? Can Tesla make any safety data/metrics available to investors so we can more accurately track the rate of autonomy progress?
Can you share the latest developments regarding the integration of dry cathode cells in the Cybertruck?
When will the lower-cost model launch? And at what price point?
Is there a supply continuity plan for LFP cell supply in the US pending tariffs or potential Chinese export restrictions - this includes both Megapacks and vehicles.
Has Tesla given up on ramping up its solar roof?
What is the status on mass production of the Tesla Semi? How do you project it will affect revenue at scale?
We’ve submitted our own question regarding FSD below:
Tesla frequently highlights the number of miles between critical interventions as a key safety metric for FSD. Could Tesla consider publishing these figures quarterly to provide investors with greater clarity on FSD's progress?

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?
