When the refreshed Model S was revealed this summer, we were introduced to a brand new user interface. An interface that was different from all other Teslas.
Tesla Model S UI
The feature set of the new software is essentially the same as other Tesla models, minus any features that are exclusive to the refreshed Model S, such as Active Road Noise Reduction.
However, the new UI does bring some capabilities that make it easier to use and more versatile.
Some of the biggest changes in the UI include customizable buttons along the bottom of the screen.
It also introduces the ability to drag and dock windows to different parts of the screen.
There are many smaller changes as well, such as a mini music player that sits on top of the map. The mini player gives you quick access to music controls used most often, such as skip and pause.
The new Model S and Model X contain Tesla's latest infotainment hardware, known as MCU 3. It features a more powerful processor, the AMD Ryzen, instead of the Intel Atom processor that is used in MCU 2.
MCU 3 gives Tesla the ability to have a richer UI. The animations in the new UI are smooth and fluid when dragging windows and tapping buttons.
Up until recently Tesla's MCU 3 was exclusive to the new Model S and Model X, however recent Model Y vehicles coming out of China now also include the new MCU.
Although new Model Ys in China now feature Tesla's latest MCU, they are still running the same UI that is found in all Model 3 and Model Y cars.
The speculation began whether these Model Ys would be upgraded to run the new UI that is found in refreshed Model S vehicles. Since they use the same hardware, they should both be capable of running the same software.
New User Interface Coming
A new document that was presented to the European Union outlines changes coming to the Model Y. The document confirms that new 2022 Model Y vehicles, known as V20 will indeed support the new user interface that is used on the new Model S.
The new interface will need to be adapted to a slightly smaller screen since Model Ys have a 15” screen instead of the Model S' 17” screen. However, the bigger adjustment and likely the reason why new Model Ys are not running this new UI yet, is because the software still needs to be adapted to support a single screen.
Since Model 3 and ModelYs only contain a single screen, all the information that is included in the Model S' intrument cluster needs to also appear on the Model Y's main screen. This includes information such as the car's visualizations, speedometer and more.
It's not clear whether visualizations in the Model Y will be permanently docked to the side of the screen like they are in current Model Ys, or whether Tesla will treat them as an app and let you move them around or even hide them.
Current Model 3 / Model Y
The big question on everyone's mind is whether current Model 3 and Model Ys will support the new UI.
There has been no official word from Tesla or Elon Musk, but we expect that this question will be asked more often and Tesla will provide an official answer in the future.
There are various possibilities and reasons why Tesla may or may not support the new UI on current vehicles.
The first possibility is that Tesla will support the new UI on current vehicles, but it will require an upgrade to MCU 3.
This won't be a cheap upgrade, likely in the $2,000-$3,000 or more range, but there would be additional benefits by upgrading the MCU as well, such as faster rebooting, faster loading of apps and even new features that may be exclusive to MCU 3.
The other two possibilities are more obvious, either Tesla will support the new UI on MCU 2 or they won't.
There is currently speculation and good arguments for both sides.
Up until 2017 Tesla was releasing vehicles with MCU 1. All Tesla UI updates in the past have applied to MCU 1 and MCU 2 vehicles. Of course, there are some features that are exlusive to MCU 2, like Tesla Theater, but the look and feel of the interface is the same across the vehicles.
It's possible that Tesla will follow a similar approach and make the new UI available to all.
There are other smaller reasons, such as Elon saying that Auto Shift is coming to all Teslas. That feature is exclusive to the new UI thus far.
There are various other reasons that lead us to think that Tesla may bring the new UI to all vehicles. This may mean that some features such as window dragging or window docking get dropped, but it's very much possible we'll see the new UI in all Teslas.
As many reasons as there are for Tesla supporting the new Model S UI on older Teslas, there are just as many reasons why Tesla won't be able to.
It's obvious that the new interface requires more horsepower, more than MCU 1 or maybe even MCU 2 can deliver. The UI lets you drag apps around. It lets you have multiple apps on screen at the same time, but these more intensive features could be removed for vehicles that may not be able to handle them.
Perhaps the most convincing reason for the new UI not becoming available for all vehicles is that Tesla engineers have said MCU 2 isn't capable of running the new interface. These comments were made by a couple Tesla engineers, so it's definitely not official by any means. They were also said when the new Model S was released this summer, so it's possible a lot has changed since then.
One thing is for sure. Tesla has a history of supporting older vehicles, regardless of the model year. In fact, Tesla still delivers updates to the original Model S that was released in 2012. If Tesla can find a way to bring the new UI to all Teslas, then they most likely will.
Elon tweeted just yesterday that Tesla will be releasing a Holiday Update this year with many ‘cool' features. Who knows what's in store for us. However, just like Christmas, lets temper our expectations and be thankful for anything we receive.

So, with Halloween all squared away, the next big holiday coming up is Christmas. Each year, Tesla releases a big Holiday update packed with features. Last year’s update included some awesome features, including alternate routes, the Vision upgrade for Park Assist, Speed Cameras and Traffic Light icons, and the Automatic Blind Spot indicator, among others.
We already know that update 2024.44 - the Holiday Update Branch - is coming with Blind Spot Monitoring while Parked, Supercharger Improvements, and more. But, we’ve got a ton of good ideas that we hope will make the list, so put down your pumpkin spice, and grab your egg nog. It’s the holidays, and it’ll be Cybertruck’s first Christmas, so let’s celebrate!
Apple Watch App
First up—the Apple Watch app. This has been a highly requested feature over the past couple of years, and it looks like Tesla is listening. Tesla has apparently already begun development to support the Apple Watch in app update 4.38, so we’re expecting this to arrive as part of the big Holiday update. We’d love to see an equivalent app for Android-based watches, too.
Phone Left on Charger Alert
It’s easy to forget your phone inside of the vehicle, especially if it’s on the phone dock. A simple app alert that a phone has been left in the vehicle would be really useful. Tesla could potentially even tell the difference between a driver’s phone and a passenger’s phone, depending on the vehicle’s profile being used or which doors were open and closed.
Either way, just receiving an app notification if a phone is left in the car would be really useful, especially since your phone is your car key.
Live Activities
Not a Tesla App
iOS introduced support for Live Activities with iOS 16.1 in October 2022. Live Activities are auto-updating, persistent notifications that can provide real-time information about a certain task. Live Activities are used to provide real-time information about your Uber arrival or the status of a flight. In Tesla’s case, they can be used for instances where up-to-date information may be important, such as when Supercharging or when Sentry Mode is active.
Arrival State of Charge
A popular request among Tesla owners is the ability to set a desired battery charge percentage upon arriving at a destination. This past year, Tesla has added several features to the app’s Trip Planner, including waypoints. Although the app lets you choose a starting charge percentage, it does not let you pick the state of charge at your destination.
If you’re traveling somewhere without a nearby charger, this becomes an issue. It’d be nice if the Tesla app let users pick their desired state of charge at arrival, and the route planner would automatically recommend charging stops and durations to reach that target.
Not a Tesla App
Light Show Support
Tesla Lightshows are great, but they could be made even better with Tesla app support. At the very least, it’d be great to be able to start/schedule or stop a light show from the app.
To really make light shows shine, Tesla could add the ability to create a light show directly from the app. Right now creating a light show involves using the open-source app xLights on a computer, so a simplified version of it running in the app would make it accessible to a lot more users.

Similar to an in-vehicle preconditioning button for 3rd party chargers, the Tesla App should also have a button to precondition the battery. This will make it easy for users, especially those who don’t have home charging – to get their vehicles ready for DC Fast Charging before departing.
Garage Door Controls
Tesla owners with HomeLink can control their garage doors directly from the vehicle. However, the Tesla app currently only allows users to open the first programmed garage door and doesn’t give the user access to any of the other programmed doors. Adding the option to choose which garage door to open via the HomeLink button would be a valuable addition—especially useful when paired with Actually Smart Summon.
Drive Stats
While Tesla already records and displays charging sessions in the app’s Charge Stats section, it’d be really helpful if Tesla also added the ability to record drives. That way, you could easily track how much your vehicle was driven on a particular day, week, or over the course of the year.
If you have any other suggestions, let us know in our forums. Who knows, some Tesla product managers may even be listening.
Tesla has added payment plan options to its shop items for the first time. They’ve partnered with Klarna, a deferred payment provider, to spread the cost of items across multiple payments. For now, this appears to be limited to the Tesla Shop in the United States—no support for other regions quite yet.
Payment Options
Klarna’s primary payment option allows buyers to get 0% APR for 6 weeks, with 4 payments. The payment schedule is essentially one payment every two weeks for whichever product you buy - enabling you to buy now, and pay later with 0% financing.
For example, the payment schedule for the $420 Wall Connector is evenly divided into four portions. Of course, you’d also have to pay for shipping and taxes, both of which will be included in your first payment.

For some of Tesla’s more expensive Shop options - like the Cybertent, this could be a fantastic means for some owners to pick up something more expensive without having to worry about interest charges on their credit card.
Klarna also offers some other payment schedules, which do have interest. While these are far more expensive and are more like credit cards, they still provide buyers a means to buy now and pay over time. These are all open loans as well, so you can pay them down at a faster rate, thereby reducing the overall interest.

FSD Payment Options?
We’d love to see an equivalent payment option available for Tesla’s FSD purchase, which is currently $8,000, even if it's bought after the vehicle purchase. The high upfront cost is likely one reason why Tesla’s FSD subscription is so popular.
It’s likely that purchasing FSD is much more popular at the time of vehicle purchase, as owners can roll the cost of FSD into their financing rather than paying the full $8,000 later on.
IPO Filing
Interestingly enough, along with today’s news that Klarna is working with Tesla, Klarna has also filed for an IPO in the United States. It is one of the first financial tech (FinTech) companies to file for an IPO in 2025 and, interestingly, one of the first European companies to conduct an IPO in the United States.
For those who trade in the financial sector, this will be one to watch—Klarna was valued at around $46 billion in 2021 and is now valued at approximately $15 billion. Partnering with a large and well-known brand like Tesla could uplift Klarna, but that’s all financial speculation.
