Tesla has begun rolling out firmware 2026.20.6.10, and according to the company's own AI leadership this is the build of "FSD v14 Lite" set to graduate from Early Access to a wide release for Hardware 3 (HW3/AI3) cars — the older self-driving computer fitted to millions of Teslas built between roughly 2019 and early 2023.
The wide-release signal
Tesla's VP of AI software, Ashok Elluswamy, indicated that 2026.20.6.10 is "the version that's likely going to wide release" for v14 Lite. That matters because until now v14 Lite has only reached HW3 cars enrolled in Early Access. A wide release would push the current-generation v14 driving stack to the broad HW3 fleet for the first time. As of reporting the build had reached only a small fraction of cars, so the wider push is imminent rather than complete. It follows the initial v14 Lite rollout for HW3 in firmware 2026.20.5.1 in late June.
What's new in 2026.20.6.10
The release notes bring several features HW4 cars already have on the main v14 branch:
| Area | Change |
|---|---|
| Mobile app | The FSD "path" and a "Self-Driving" status label now appear in the phone app whenever the system is active |
| Driving streaks | The car tracks uninterrupted-navigation milestones, celebrating 100, 250, 500, 1,000 and 5,000-mile streaks with full-screen animations |
| FSD stats | New in-app FSD statistics alongside the "Park at Destination" interface |
| Start from Park | Option to turn off the brake-confirm step when starting FSD from a parked position |
| Responsiveness | Further improvements to navigation, merges and forks, pedestrian handling, traffic lights and vehicle cut-in scenarios |
Still HW3, still supervised
v14 Lite is a distilled version of the HW4 v14 stack, compressed to fit the lower camera resolution and compute budget of AI3. It remains a supervised system: the driver must stay attentive and keep hands ready, and Tesla has been explicit that Unsupervised FSD is not coming to HW3. The Lite branch is about closing the feature gap with newer cars, not unlocking hands-off driving on legacy hardware.
What European owners should note
FSD (Supervised) is still not broadly approved for use on public roads across most of Europe, so many HW3 owners on the continent will receive the interface changes — driving streaks, the app path, the statistics screen — without yet being able to use the full driving feature. Even so, a wide HW3 release signals that Tesla intends to keep its oldest self-driving computer on the current software track rather than letting it fall behind newer cars.
Update: 2026-07-23
On 21 July 2026, the wide release flagged above began in earnest — but on a newer build than expected. After AI VP Ashok Elluswamy signalled 2026.20.6.10 as the wide-release candidate, Tesla issued a quick bug-fix point release and pushed 2026.20.6.11 to the broad Hardware 3 fleet instead, according to Tesla Oracle. The new build also merges the HW3 v14 Lite and HW4 FSD v14.3.6 firmware into a single version, so legacy HW3 cars now carry the same distilled feature set as HW4 vehicles on v14.3.6.
Update: 2026-07-26
Since 2026.20.6.11 reached the broad Hardware 3 fleet, owners have flagged a problem with the newly added low-speed reversing feature: some cars fail to detect stationary objects while backing up. In videos gathered by Not a Tesla App, HW3 vehicles reversed straight into obstacles sitting in driveways, with one owner reporting that "v14 Lite does not care about hitting things while reversing." The problem shows up far more often on the Lite branch than on the full HW4 version of v14. Reversing is new to v14 Lite, and because Tesla iterates quickly on this branch, an over-the-air fix is expected once the behaviour is diagnosed. Until then, drivers should stay ready to intervene whenever the car reverses under FSD.
