It's only been a few days since Tesla officially announced the Model Y refresh, but we’re already finding out more. While deliveries won’t begin for at least another three months, there are plenty of things to get excited about.
We covered the Model Y Refresh in detail, but it is always worth it to take a moment and appreciate all the little things Tesla has included in this version of the Model Y.
Turn Signal Stalk & Steering Wheel
Not a Tesla App
First up is the return of the signal stalk. The Cybertruck and Model 3 Refresh both shipped without a signal stalk. Instead, the signals, as well as the wiper control, were located on the steering wheel.
For the Model 3, this was met with considerable pushback, given that it was a vehicle intended for the mass market rather than enthusiasts. While it's possible to get 3rd-party stalks for the Model 3 now, Tesla has clearly taken consumer sentiment to mind when refreshing the world’s best-selling vehicle.
With the Model Y Refresh, there’s a single turn signal stalk on the left side. Based on the photos, it appears that this may be a simpler stalk than we’ve seen in the past, as it doesn’t appear to have a button at the end. Given the headlights button on the steering wheel, it’s unlikely to move forward/back for high beams as well.
The steering wheel itself is very similar to the new Model 3 but with reduced buttons, thanks to the stalk. On the left side of the steering wheel you have buttons for the Wipers and High Beams. While on the right, it looks like there will be a button for Voice Commands (soon to be the smart assistant) and the rear/front camera.
There is no right stalk, so Autopilot and shift functionality is the same as the new Model 3, which means that you’ll be using the right scroll wheel and the screen for that functionality instead.
Rear Power Reclining Seats
The new Model Y is definitely aimed at families and those with lots of stuff to move. Tesla has put some good thought into this - and has added power reclining seating, which folds flat.
At the press of a button from the trunk or with a tap on either the front screen, the rear seats can be folded flat or raised up to their normal position. That’s definitely a helpful feature, especially if you’re trying to get something big into the trunk of your vehicle - and you need to drop the seats.
Now, a single-button press does the trick, which is super convenient. The ability to fold the seats flat is also new. In the previous Model Y, the seats folded mostly flat - and they’d squish down further if you put something heavy on them, but that could potentially damage the seats.
The rear seat cushions are also a 1/2” longer than before, making them more comfortable for adults to sit in.
Rear Trunk / Lift Gate

The vehicle’s lift gate has also received some upgrades. Instead of being a “single” piece, there’s now a seam between the sides and the tail of the trunk piece. This will likely make repairs much cheaper for light rear-end accidents or other light damage. Owners can opt to replace just the trim part of the trunk instead of having to replace the entire life gate.
The rear glass has also been updated. Instead of featuring a curved edge at the bottom, it’s now much more rectangular. This appears to be a cosmetic change or tied to the new seam location.
To go along with the changes to the trunk, the new Model Y will also support the new hands-free trunk opening. Users with a supported phone will be able to automatically open the trunk simply by standing near it. This is something all new models have had since last year, but it will come to the Model Y for the first time.
Frunk
One change that didn’t make the cut is a powered frunk. While we’re disappointed that the new Model Y won’t include a powered frunk like the Cybertruck, Tesla did add a drain plug to the bottom of the frunk.
A drain plug allows the frunk to easily be used for cooling drinks during tailgating. Simply add ice and drinks.
New Speaker Placement and Double Stitching
Not a Tesla App
The new Model Y includes new speaker placements on the doors. The speakers on the door have been moved up next to the door handle. Their integration feels a lot smoother, and they’re fitted with a metal grill instead of a plastic one.
The interior also features a lot more double stitching when compared to the new Model 3. You can see this on the dash, where this is a single piece on the Model 3. While it likely adds a little bit to the cost, it makes the vehicle look a lot more premium.
The ambient lighting is also slightly different, now only reaching half the length of the door — on the front and rear doors. However, the design is sleek and fits in nicely.
Not a Tesla App
To Tow, or Not to Tow
We initially reported that the Model Y Refresh doesn’t have a tow hitch. We still stand by this point, but others have pointed out that the openable slot for the tow hitch still seems to be present.
Tesla doesn’t show the tow hitch as an option on any of the Asia Pacific sites right now - so it seems that, at the very least, the Launch Edition will not include a tow hitch. It also doesn’t show up as a feature, and the maximum tow weight is not listed as a vehicle specification.
We’re hoping that this is either an oversight or that Tesla intends to bring the tow hitch to the market as a Tesla Store retrofit and then offer it for new vehicles sometime in the future. Towing is very popular on the Model Y, but many people also use the hitch for bike racks and luggage carriers - owing to the versatility of the Y as a do-everything vehicle.
New Wheels
Alongside all the fun new features - the Model Y also comes with a new set of 20” Helix 2.0 wheels. One interesting item of note is that there is no aero cover included with these wheels, at least for now. They’re probably already quite efficient and likely wouldn’t benefit too much from aero covers like the current generation Model Y’s wheels.
This likely won’t be the only wheel option - but it is the standard for the Launch Series. We’ll likely see a 21” performance wheel option once the Performance variant arrives, as well as a cheaper 19” wheel variant with aero covers.
However, the new Helix 2.0’s are some of Tesla’s best-looking wheels, in our opinion, so there is that too. 20” wheels are a good balance in terms of looking good and providing enough rubber to dampen sounds, vibrations, and bumps. Tesla also claims to have improved handling performance and comfort, so these new wheels likely contribute to the overall experience.

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.

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?
