Following last week’s release of FSD V14.3 Lite for HW3 to a small batch of early testers, Intel-based HW3 Model S and Model X owners are now getting FSD (Supervised) v14.3 Lite, a long-awaited upgrade for drivers who have been stuck on FSD v12 for nearly two years.
The update is significant for owners of legacy vehicles, which have missed out on several major FSD improvements introduced on newer Teslas with AMD Ryzen processors and Hardware 4.
Major Improvements Over FSD v12
According to early reviews shared by Teslascope, FSD v14.3 Lite delivers noticeable improvements in several areas, including speed control and overall driving performance.
Owners are also reporting improvements to the steering wheel nag system, making the supervised driving experience less intrusive.
Tesla says v14 Lite uses technology distilled from the full Hardware 4 version of FSD v14, allowing older vehicles to benefit from improvements originally developed for newer hardware.
The release notes highlight better navigation decisions, smoother highway merges and forks, improved responses to pedestrians and traffic lights, and more natural handling of vehicles cutting into traffic.
Steering and lane centering have also been refined.
Not All FSD v14 Features Are Available
Despite the improvements, the Intel-powered Model S and Model X are not receiving the complete FSD v14 experience.
Early reports indicate these vehicles are missing several features available on newer models, including Start from Park, Arrival Options, reversing, and Actually Smart Summon.
Interestingly, Tesla’s general v14.3 Lite release notes mention parking, unparking, reversing, and Arrival Options. However, those capabilities do not appear to be available on the older Intel-equipped vehicles receiving the update.
The rollout follows Tesla’s earlier expansion of FSD v14 Lite to HW3 vehicles, as the company continues working to bring newer self-driving improvements to its aging hardware.
It’s a big leap for owners of older S and X vehicles, even with a few newer features still missing.
