The Tesla Cybertruck buzz continues to ramp up. Elon Musk says it will change the road, and he plans to make the futuristic truck his daily driver. Thanks to its distinctive design and outstanding performance capabilities, millions of buyers are on the wait list to drive this amazing truck.
Matthew Donegan-Ryan, a shareholder who attended Tesla's Investor Day, had the chance to speak with senior Tesla executives and learn more about Cybertruck. Several investors were sharing information about Cybertruck, but Matthew Donegan-Ryan has posted extensive videos about his conversations with Tesla executives.
Sizes and Variations
According to rumors, the Cybertruck pre-production beta that was on display at Investor Day is how the truck would appear if it were available for purchase right now. The Cybertruck is about 5% smaller than the prototype unveiled in 2019, but despite being a smaller vehicle than the Ford F-150 Raptor, it has more usable space. The Ford Super Crew Raptors at the event were comparable to the Cybertruck, which is slightly smaller. The size reduction means that the Cybertruck can only hold five passengers instead of six. It's expected to weigh between 6,500-7,500 pounds. Other investors are reporting 7,000 pounds
The Cybertruck will come in two versions: a dual-motor base model and a high-end performance model. It was initially believed that the top trim would be a quad motor, but conversations with Tesla staff seemed to suggest that Tesla would forego developing a quad-motor powertrain in favor of a tri-motor powertrain for the Cybertruck. All Cybertruck configurations will come standard with rear-wheel steering.
Largest Display in a Tesla
The Cybertruck will have Tesla's largest display ever, measuring 18.5 inches diagonally, however it'll come without a gauge cluster, or heads-up display. The redesigned Model S and Model X have a 17" center screen, while the Model 3 and Model Y include a 15" center display.
A combination of a typical round steering wheel and the yoke found on the Model S and Model X, the steering wheel will be round on the sides with flat top and bottom edges.
Unlike the F-150 Lightning, the front bumper grille does not open along with the hood. The production version of the Cybertruck windshield light bar will have amber lights, just like the Tesla semi, to indicate that the truck is wider than the standard 80 inches.
Wheels and Suspension
Highly advanced air suspension will come standard on every Cybertruck. Staff told the intrepid investor that Cybertruck can handle pretty much anything. "I was told very directly that they have tested the air suspension and they're confident it can handle Baja-style racing."
The Cybertruck will have 18-inch wheels, and at the very least, all-terrain and all-season standard tire options will be available. The tire's dimensions are 285/65 R18, or 35 inches by 11.25 inches by 18 inches. The company in charge of making the tires for the Cybertruck will be Goodyear. Donegan-Ryan estimates each tire will cost $385.
No Self-Presenting Doors
The doors on the Cybertruck won't self-present themselves like the doors on the Model X. Unlike the prototype's stainless steel bumpers, the Cybertruck's production beta's bumpers and side skirts are made of black plastic and are five-mile-per-hour impact compliant. The side-view mirrors are supposedly removable, but no confirmation of that.
New Team is Developing Accessories for Cybertruck
The 48-volt architecture used by the Cybertruck will provide more power, lighter and less expensive wiring, and a smaller accessories battery. For the vehicle, Tesla has created a Cybertruck Accessories Team, and rather than working with aftermarket businesses to build add-ons, Tesla will do it themselves. Off-roading, camping, and racing are the three subgroups of the Accessories team.
With millions of people on the waiting list in North America, it appears that list will not be opening up in Europe. With it's immense size, Donegan-Ryan says there are no plans to have this beast on the narrow European roads.
The Cybertruck will be a strong and adaptable vehicle, suitable for off-roading, camping, and even racing, according to the most recent information about it. The Cybertruck is poised to have a big impact on the pickup truck market thanks to its distinctive design and impressive features.

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.

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.
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?
