Tesla has started rolling out FSD v14 “Lite” to its Hardware 3 (HW3) cars, the company’s AI chief Ashok Elluswamy confirmed today. The build, firmware version 2026.20.5.1, is going out first to early-access drivers. It’s the first major Full Self-Driving update for the roughly 4 million HW3 vehicles that had been frozen on FSD v12.6 since early 2025 — but it remains a supervised, hands-on Level 2 system.
Amidst ongoing scrutiny of FSD development, Tesla is now addressing a significant installed base of older hardware that had been stagnant on previous software versions.
This update extends advanced autonomous capabilities to a large segment of Tesla's fleet, demonstrating progress in scaling software to diverse hardware and potentially accelerating wider adoption and data collection for FSD.
Approximately 4 million HW3 Tesla vehicles will now receive updated FSD capabilities, moving them beyond prior limitations and enhancing the pool of active FSD users, albeit still under supervised conditions.

HW3 Tesla owners gain access to improved FSD features, enhancing their vehicle's capabilities.
Increased FSD data collection from a larger and more diverse fleet accelerates the refinement and expansion of Tesla's autonomous driving systems.
Broader public familiarity with and acceptance of advanced Level 2 autonomous driving systems could grow, impacting regulation and future adoption of higher autonomy levels.
