Tesla Rolls Out FSD v14.3 Lite to Intel HW3 Model S/X for First Time
Tesla has begun rolling out FSD (Supervised) v14.3 Lite, via update 2026.38.5.1, to Model S and Model X vehicles with HW3 and Intel processors, according to an announcement from the official Tesla Super Intelligence account on X. It is the first time these vehicles have received the distilled FSD branch. The release notes state that it incorporates the intelligence from HW4 V14 along with better handling of merges, pedestrians, traffic lights, and cut-ins, with fewer false slowdowns and smoother steering.…
- FSD v14.3 Lite reaches HW3 Intel Model S and X with version 2026.38.5.1.
- Still missing Arrival Options, starting FSD from Park, FSD reversing, and Smart Summon.
🔎 Why it matters: It is the first time Intel-based HW3 Model S and X vehicles have received the distilled FSD v14 branch, although Tesla has confirmed HW3 will not support unsupervised FSD or FSD v15.
📈 Upside: Better handling of merges, pedestrians, and traffic lights, with fewer false slowdowns and smoother steering, according to the release notes.
📉 Risk: Tesla has confirmed HW3 will not support unsupervised FSD or v15, and Arrival Options, starting FSD from Park, and reversing remain unavailable.
