Tesla starts FSD v14 ‘Lite’ rollout to HW3 cars

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.
