Tesla has officially begun rolling out Full Self-Driving V14 Lite to owners running Hardware 3 — the chip platform that shipped in Model 3, Model Y, Model S, and Model X vehicles from 2019 through early 2023. The OTA update is live now, and owners across the country are already reporting the notification in their Tesla app.
FSD V14 Lite has just officially started rolling out to @Tesla owners with HW3! It’s finally here!

V14 Lite introduces many of the same features for HW3 owners as V14 for HW4 owners, including:
• Speed profiles
• Start self-driving rom park
• Arrival options
• and much more! pic.twitter.com/M1yAvpxAbJ
The rollout marks the end of a grueling wait. HW3 vehicles have been frozen on FSD v12.6 since mid-2024 — sitting on the sidelines while HW4 cars received two landmark upgrades in V13 and V14. That 18-month software drought is officially over.
What's New in FSD V14 Lite
V14 Lite is not a stripped-down consolation prize. Tesla's AI chief Ashok Elluswamy put it plainly: HW3 owners will "essentially have all the same features" as the HW4 fleet. The "Lite" designation refers strictly to the size of the compressed neural network running under the hood — not the experience behind the wheel.
Beyond new features, V14 Lite brings the same architectural leap that made V14 feel like a step-change on HW4: a unified end-to-end neural network that processes the entire driving environment in a single pass. The result is noticeably smoother lane changes, more confident unprotected left turns, and better roundabout handling — driving behavior that actually feels human rather than scripted.
HW3 vs. HW4: The Real Difference
Feature parity is the goal — but physics still applies. Because HW3 runs a compressed version of the neural network on older silicon, drivers should expect slightly longer reaction times and a bit less precision in edge cases compared to HW4 vehicles. The lower-resolution cameras on HW3 hardware also reduce long-range detection capability. Tesla had to retrain the models from scratch to account for the different camera inputs.
| Capability | HW3 (V14 Lite) | HW4 (Full V14) |
|---|---|---|
| Start from Park | ✓ Supported | ✓ Supported |
| Speed Profiles | ✓ Supported | ✓ Supported |
| Arrival / Parking Options | ✓ Supported | ✓ Supported |
| Reverse & Gear Shift | ✓ Supported | ✓ Supported |
| High-Res Camera Input | ✗ Not available | ✓ Full resolution |
| Unsupervised / Robotaxi | ✗ Hardware limit | ✓ Future roadmap |
One thing is non-negotiable: FSD V14 Lite is still a Level 2 driver-assistance system. Drivers must remain attentive and be ready to take the wheel at any time. That will not change on HW3 hardware — the compute ceiling is a physical reality, not a policy decision.
What Happens Next
The North American rollout is underway right now. Tesla has confirmed plans to expand V14 Lite to international markets after the domestic rollout is complete, though the company has not committed to specific dates abroad — regional regulatory approvals and model retraining for local road conditions add meaningful lead time outside the U.S..
To make sure you're first in line, set your software update preference to Advanced (Controls → Software → Software Update Preference) and keep your car on Wi-Fi. The OTA notification will come through your Tesla app when your vehicle is queued up.
