Tesla’s 2026.38 software update quietly added Grok support files to Model 3 and Model Y builds for cars with the older Intel Atom infotainment computer, and one owner with root access has already switched the in-car assistant on. Tesla hasn’t announced Grok for Intel cars, and for now it doesn’t officially support them.
The find was reported by Not a Tesla App on October 31. A video first posted by @angellvroo and shared on X by @Luckeronisekcz shows Grok and the full-screen parked visualization running on an Intel Atom car after the owner flipped the feature flags. Lucker described the frame rates as “surprisingly solid.”
What changed in 2026.38
Tesla builds a separate software package for each vehicle type. Until recently, the Intel Model 3 and Model Y packages didn’t include the Grok integration code at all, so there was nothing to turn on. That changed with 2026.38, which began rolling out in late September.
Well-known Tesla hacker green (@greentheonly) confirmed the change in a reply on X: “the Intel model 3 did get them added in 2026.38 so enabling it looks feasible indeed.” He also pointed out the limit. Older Model S and Model X cars on the same Intel chip, the cars the “MCU2” label strictly refers to, still don’t have the Grok support files.
Tesla’s own Grok support page still lists an AMD processor as a requirement, along with software 2025.26 or later and Premium Connectivity or Wi-Fi. The 2026.38 release notes mention Grok only to say its beta label is gone, which is the change we covered with FSD v14.3.13.
Will Tesla turn it on?
Nobody outside Tesla knows yet. Grok does most of its work in the cloud, which is why owners think the slower Intel chip can keep up, and the video backs that up. Not a Tesla App suggests the files could be groundwork for a wider release, possibly with this year’s Holiday Update.
There’s a reason for caution, though. The assets for full-screen parked visualizations have sat on Intel cars for a while and were never enabled. Asked whether Tesla would bring Grok to Intel cars, green said “I don’t really know” and suggested this could be the start of a long stretch of compatibility testing.
Rooting a car isn’t something most owners can or should do. For everyone else, the official answer remains AMD only.
The EVX Take
Tesla doesn’t ship code for fun, and adding Grok files to a specific set of Intel builds looks like deliberate prep work rather than leftover clutter. Japan has a real stake in this: Model 3 deliveries here started in 2019, so a good share of the early Model 3s on Japanese roads were built in the Intel era and have been watching Grok from the sidelines. If Tesla flips the switch, those owners get the biggest feature upgrade their cars have seen in years without a hardware swap. Owners can check which chip they have under Controls > Software > Additional Vehicle Information.
