Tesla says Full Self-Driving (Supervised) v14 Lite is now rolling out to eligible older Model S and Model X vehicles that combine an Intel infotainment computer with HW3 (AI3) self-driving hardware.
The announcement, posted by Tesla's Tesla Super Intelligence account on October 13, 2026, expands access to this FSD generation beyond newer vehicles and HW3 cars with AMD-based infotainment systems. The rollout is beginning, not complete, and availability still depends on a vehicle's hardware, software and regional eligibility.
What's changing for legacy Model S and X owners?
The important news is which vehicles can receive v14 Lite. Legacy Intel-based Model S and Model X cars had not been part of the earlier v14 Lite rollout.
Software trackers associate the expansion with Tesla firmware 2026.38.5.1, first tracked on October 13. This build also includes FSD v14.3.12 for eligible HW4 cars, while eligible HW3 vehicles receive v14.3 Lite.
Not all cars receive the same interface or supporting features. Intel infotainment hardware may have additional limitations compared with AMD-equipped vehicles, and Tesla has not published a complete Intel-specific feature-by-feature compatibility list. Owners should use the release notes shown in their own cars to verify what is enabled.
What is FSD v14 Lite?
FSD v14 Lite is a version of Tesla's supervised driver-assistance software intended for HW3 vehicles. Tesla's general v14 Lite release notes discuss improvements to responsiveness, merging, pedestrian interactions, comfort and driving profiles, with capabilities depending on vehicle eligibility.
Those are general release notes, not independently verified new performance gains or a promise that every listed feature works on legacy Intel Model S or Model X vehicles.
FSD remains supervised: an attentive driver must monitor the road, keep responsibility for the vehicle and be ready to intervene. Receiving this update does not authorize driverless operation.
What to watch next
Key questions include how quickly the update reaches Intel-equipped cars, which model years and configurations receive it, and which features remain limited by their older infotainment hardware.
For owners, the practical next step is to check the car's available software updates and its own release notes rather than assume every vehicle has received 2026.38.5.1.
