Tesla has started testing a new build of FSD v14 Lite, the version of its driver-assistance software built for cars with the older Hardware 3 (HW3, also called AI3) computer, and the executive who leads Tesla’s AI team says it could be the one that reaches every eligible car. Software version 2026.20.6.10 began rolling out on July 20, 2026, but only to a small early access group described as “mostly belonging to the influencer community,” according to Tesla Oracle’s review of the release.
Tesla AI chief Ashok Elluswamy wrote on X that this build is “likely going to wide release,” as reported by Not a Tesla App. Tesla has not given a timeline for when the update will reach the full HW3 fleet, and as of this writing it is still limited to early testers.
Why this matters if you have an older Tesla
Hardware 3 shipped in Tesla vehicles before the company moved to its newer Hardware 4 computer, and HW3 cars can’t run the full-size FSD v14 that HW4 cars already have. Lite is a smaller model distilled from HW4’s version 14 so HW3 cars can keep gaining capability without a hardware swap, per Tesla’s release notes for 2026.20.6.10. According to Not a Tesla App, HW3 cars are also expected to be excluded from the next major version, FSD v15, which is built for unsupervised driving — making Lite the main path HW3 owners have to newer features for now.
What changes in this build
Tesla’s release notes and early tester accounts, summarized by Tesla Oracle, point to several practical changes:
- Starting Self-Driving from Park no longer requires pressing and releasing the brake pedal to confirm.
- New “Arrival Options” let you choose where the car pulls over — parking lot, street, driveway, garage, or curbside.
- A new Self-Driving app in the app launcher tracks your subscription and activation status.
- Testers describe smoother highway driving, with fewer unnecessary lane changes and better traffic-light behavior, along with new parking and reversing capability.
Early testers told Tesla Oracle the update feels “so much safer” than the older v12.6.4 software most HW3 cars were still running, though they noted parking maneuvers still need work.
What to do now
If your Tesla has Hardware 3, there’s nothing to opt into yet — the early access group is small and Tesla hasn’t said when a broader rollout starts. Check your car’s software version under Controls > Software, and watch for an update in the coming weeks if you’re not already in the early access program. As with any FSD (Supervised) release, you’re still required to keep your hands on the wheel and attention on the road; the feature assists with driving, it doesn’t replace you.
