On June 10th Tesla showed off the new Model S Plaid and it’s completely redesigned interface. The new UI contains many new features and enhancements, such the ability to customize the buttons at the bottom of the screen so that you can have your most used apps easily accessible. It also includes the ability to drag and drop apps between the left side and right side of the screen. A new mini player also makes music controls always easily accessible. You can read about all the new features in the new UI, which we covered last month.
Since the day of the event, everyone has wanted to know whether this new UI would be carried over to previous cars, since the cars' displays differ quite a bit. Previous Model S and X vehicles contain vertical displays, and the Model 3 and Model Y do not contain an instrument cluster, so people started to wonder whether Tesla would be able to adapt the new UI for these other dimensions.
Elon took to Twitter and confirmed that a new UI will indeed be coming to all Teslas. We anticipate that this new UI will be similar to the UI in the new Model S, although Elon was not specific on Twitter. Elon simply said that an “updated UI coming with FSD wide release,” which doesn’t necessarily mean it will be the same as the UI in the new Model S. However, Tesla has never had different UIs for different vehicles in the past. Even when they overhauled the UI various times in the past, the changes always trickled down to older vehicles as well.
Yes, updated UI coming with FSD wide release. All cars with FSD computer will have new “mind of car” view. All 3/Y can be upgraded to have FSD computer.
It’s clear however that the UI needs some big changes before it can work on older vehicles. We may see some features dropped or changed. For example, on the Model 3 and Model Y, the left side of the screen is used for car visualizations and takes up a significant amount of the screen. Tesla could allow stacking of apps on the right side or the cars may be limited to a single app at a time.
In December of last year, Elon said that we will have multiple display options, so that feature may be included in this update.
Although we may not be able to hide the car visualizations completely, we may be able to choose how big or small they are on the screen. It would be great to see an option where the car visualizations are hidden completely and we merely keep a small window with the important information, such as current speed, speed limit and Autopilot details.
As for the vertical screened Model S and Model X, it’s possible Tesla may just stack the apps vertically instead of horizontally and the rest of the layout would remain largely unchanged since those cars include an instrument cluster.
Elon mentions that the new UI will come with the FSD wide release, which honestly we don’t know when that’s coming. However Elon has said recently that he expects FSD to be ready “soon.” It’s been pushed back several times since we first expected it in April, but it looks like Tesla may be getting close. We expect the FSD beta to be limited to beta testers initially, but hopefully it won’t have to wait too long after that.
The other tidbit Elon teases is that the new UI will include the “mind of the car” view. We covered this before and in short, we expect this to be new and improved car visualizations. As Tesla gets better at understanding and interpreting the world around us, the car visualizations also improve and we think this will be a major step forward in what we see on the screen.
We don’t know exactly what the future holds, but it’s exciting to hear that a new UI will be coming soon and new car visualizations will be coming soon.
Update: Tesla delivered v11 with an updated UI based off of the new Model S in the 2021 Holiday Update.

In a new video posted to X, Tesla is showing the progress of its first Lithium Iron Phosphate (LFP) cell manufacturing factory in North America. The facility, located in Sparks, Nevada, will be used to produce LFP battery cells for Megapacks and Powerwall.
However, the implications of this new factory extend beyond Tesla Energy. By on-shoring the production of these cost-effective batteries, Tesla is not only securing its energy supply chain but also opening the door to potentially reintroducing LFP-based vehicles in North America.

The immediate beneficiary of the new Nevada LFP facility is Tesla’s Energy division. LFP chemistry is ideal for stationary storage products like Megapack and Powerwall. It offers a very long life cycle, is extremely thermally stable and safe, and is significantly cheaper to produce than nickel-based batteries, partly because it contains no cobalt.
Until now, Tesla has relied on suppliers like CATL in China for these cells. A dedicated, domestic supply will enable Tesla to dramatically ramp up Megapack production to meet North America’s increasing demand for grid-scale energy. On the other hand, Megafactory Shanghai continues to utilize CATL’s LFP batteries and will support the rest of the world.
Tesla first revealed that they were planning to onshore LFP production in North America at the Q1 2025 Earnings Call, which will help them avoid costs, innovate in new technology, and insulate themselves from geopolitical supply chain risks.
A Potential Return for LFP Vehicles?
Another exciting application for Tesla is what this new factory means for Tesla’s budget-oriented lineup. For years, Tesla has been constrained in its ability to offer LFP-based vehicles in North America. While LFP packs are used in other markets for specific standard-range RWD vehicles, tariffs on important Chinese cells made it difficult to import these cells for use in North America.
With a domestic supply of LFP cells produced in Nevada, this tariff-related barrier will be mostly eliminated, pending the sourcing of lithium from a North American site. This is likely to lead to the reintroduction of LFP-based vehicles to the North American market, possibly in late 2026 or 2027.
An American-made LFP pack could lead to a more affordable base Model 3 or Model Y, or potentially help Tesla cut costs on the next-generation Affordable Model even further. This helps to give customers a lower-cost entry point without sacrificing a lot of range, and with the added benefit of being able to regularly charge to 100%.
Mega Nevada
With Mega Nevada now progressing well, Tesla is in an excellent position to continue iterating on its vertical integration and scaling Megapack and Powerwall—two of Tesla’s fastest-growing businesses—further. There are tons of benefits for consumers in the future as Tesla continues down this path, with more affordable Powerwalls for the home, cheaper electricity prices thanks to grid-forming Megapacks, and cheaper LFP vehicles.
The next major upgrade for Tesla’s in-car experience is pretty much already here - just hiding beneath the surface, awaiting the flick of a switch. According to new details uncovered by Tesla hacker Greentheonly, a fully functional version of the Grok conversational AI assistant is already present in recent firmware builds, just waiting for Tesla to activate it.
The feature, which is currently behind a server-side switch, could be enabled at any time by Tesla for vehicles running update 2025.20 and newer. The findings provide a better picture of what we already learned from Green’s breakdown on Grok last month.
Grok’s Requirements
@greentheonly on X
According to what Green determined from the latest software builds, the foundation for Grok was laid with update 2025.14, with more abilities and functionality added in 2025.20 to flesh it out. He also determined exactly which vehicles will be receiving Grok.
In terms of hardware, any vehicle with a Ryzen-based infotainment computer will receive Grok. This means that vehicles with the older Intel Atom processor will not be supported, at least initially. The underlying Autopilot hardware is not a factor, as Grok’s processing is not done in-vehicle.
Grok will also require premium connectivity or a Wi-Fi connection for the vehicle. At this point, we’re not sure whether Grok in your Tesla will also require you to sign up for SuperGrok, X Premium, or X Premium+, but Tesla is requiring you to sign into your Grok account. It’s just not clear whether the free version of Grok will work, or if you’ll need the premium version.
Grok User Experience
@greentheonly on X
Green also revealed the user interface for Grok for the first time. You’ll find many of the same features from the Grok app, but surprisingly, it looks like it’ll have a dark UI, even if you’re using light mode in your vehicle.
It appears that there will be a Grok app, likely for settings. However, Grok will largely operate in a modal, similar to voice commands, which are displayed near the bottom left corner of the screen.
There’s an on-screen microphone button, as well as drop-down menus for the voice and type of assistant you’d like to use.
Similar to the Grok app currently on mobile devices, you’ll be able to select from a set of voices and then define their personality. The available voices for now are the standard Ara (Upbeat Female), Rex (Calm Male), and Gork (Lazy Male).
There’s also a settings button, which, when expanded, allows you to enable or disable NSFW mode (including swearing and adult topics), as well as a Kids Mode, which will tone Grok down to be suitable for when kids are in the car.

How Grok Will Work (Button / Wake Word)
Users will be able to activate Grok by pressing a button, likely the same one that activates voice commands today. Grok will then remain enabled for the duration of your conversation, allowing you to go back and forth, asking and answering questions. To end your conversation, you’ll press the mic button again.
While it doesn’t appear to use a wake word yet, Green says that some code refers to a wake word, so it’s possible that this could be an option Tesla plans to activate in the future.
Replacing Voice Commands
The most significant implication of Grok’s future integration is in its potential to fully replace the existing and relatively rigid voice command system. Green notes that internally, this feature is part of the car assist module, and that eventually, the plan is for Grok to take over car control functions.
Unlike the current system, which requires specific phrases, a true conversational AI like Grok can understand natural language. This will enable more intuitive requests, completely changing how drivers interact with their car.
Language Support
@Greentheonly/X
Grok will also launch with multi-language support, similar to its current abilities in the Grok app. Green says that it already appears to have support for English and Chinese and one or two other languages.
Release Date
Grok appears ready to go from a vehicle standpoint, but Green wasn’t able to actually test it out. While development appears to be nearly complete in the vehicle, Tesla and xAI may still be working on some server-side changes to better integrate with the vehicle. If they plan for Grok to replace voice commands on day one, then it’ll need to be trained and be able to execute a variety of vehicle commands.
It’s possible Tesla is actively testing Grok or adding server-side changes to replace voice commands. However, it looks like vehicle development is nearly complete and Grok could launch as soon as the next major Tesla update, which is expected to be update 2025.24.
