This will have a minor refresh for the Model S and Model X
Edmunds
Tesla has found itself in a bit of a pickle. Its flagship vehicles, the Model S and Model X now have a similar feature set as the recently released new Model 3. While the new Model 3 does have an improved suspension, the Model S, Model X, and soon the Cybertruck are still the only Tesla vehicles with an air suspension. However, the new Model 3 now includes many features that were previously exclusive to the Model S/X, such as ventilated seats, a quieter cabin, and a rear screen, reducing the feature set gap between Tesla's economy and luxury lines.
Ambient Lighting for Model S & X
However, it looks like the Model S and X will be catching up in some regards. Greentheonly was able to find references to the Model S/X receiving the same RGB ambient lighting treatment as the new Model 3. The references were discovered in one of Tesla's recent firmware updates. As Green points out, Tesla is much more careful nowadays to include any code that may reveal upcoming features. Given the discovery, he believes that Tesla is already implementing or will soon start implementing the feature on its assembly lines.
Upcoming Minor Refresh
One of our sources has confirmed that the S/X will not only receive Tesla's latest interior lighting feature in an upcoming refresh, but that it will also be outfitted with a front bumper camera. It's unknown whether Tesla will introduce both these features simultaneously or in a phased manner. Considering Tesla's known strategy of incorporating upgrades as they deplete available parts, it wouldn't be surprising if they took the latter route.
Model Y Envy
After Tesla China's surprising reveal of an upgraded Model Y with some modifications like adding ambient lighting to the dashboard, the spotlight is now turning to what's in store for the Model S and Model X. The Model Y's changes, touted as its "evolutionary debut" by Tesla China on its official Weibo account came out of nowhere.
Ambient Lighting is a Must
Ambient lighting has always been a staple in luxury car interiors, enhancing the ambiance and offering a more sophisticated driving experience. For years, Mercedes-Benz, BMW, Audi, Lexus, Jaguar, Porsche, Volvo, and others have used ambient lighting, also known as mood lighting. That didn't seem to matter all that much to the Model S and Model X, which have worked their way up the luxury brand market.
But now that ambient lighting is in the Model Y, Model 3, and the upcoming Cybertruck, the omission of the features from the luxury models is noticeable.
With the Model Y's recent update featuring ambient lighting on its dash and front doors, there is speculation about the extent to which this feature will be introduced in the S and X. Will Tesla stick to the approach seen in the Model Y, or will they amplify the luxury feel with an almost 360-degree wraparound, similar to the new Model 3?
Front Camera
In addition to ambient lighting, the Model S and Model X will get a front bumper camera. We expected to see it in the Model 3 refresh. Still, it mysteriously didn't make the long list of changes when the car was revealed, even though the camera was spotted in various Tesla photos. However, the Cybertruck does have a front bumper camera.
It's not known if the front bumper will be used to improve Autopilot and Full Self Driving or if it could be more about enhancing parking assist capabilities. The front camera is not available in the existing fleet, which would put those vehicles at a disadvantage if FSD utilizes the camera in future updates.
With the last quarter of the year unfolding, Tesla enthusiasts and potential buyers have much to look forward to. A new Model 3, slightly refreshed Model Y, the Cybertruck, and maybe even an enhanced Model S and X are yet to arrive before Santa.

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.
