Tesla Begins Rollout of FSD v14 'Lite' for Hardware 3 Vehicles

Tesla's AI chief has confirmed the release of Full Self-Driving (FSD) v14 'Lite' to its extensive fleet of Hardware 3-equipped vehicles. This update, firmware version 2026.20.5.1, marks the first significant FSD advancement for these cars since early 2025, reaching early-access drivers first. It aims to bring crucial feature enhancements to roughly four million vehicles that were previously limited to FSD v12.6 capabilities, though it remains a supervised Level 2 system requiring active driver attention.
