FSD News

FSD 14.3.11 for HW4 and a new 14.3 Lite for HW3 both ride firmware 2026.33.5. Stack notes look like the prior 14.3.10 / 14.2 Lite family. Automatic Collision Evasion stays on the HW4 build with clearer Scenario 1 and Scenario 2 wording.

Early-access cars are downloading firmware 2026.27.11 with FSD 14.3.10. The release notes match 2026.27.10, including Automatic Collision Evasion.

FSD 14.3.10 on firmware 2026.27.10. The stack bullets still match 14.3.9. Early cars showed a notes header that said v14.3.9 includes under a 14.3.10 title. Tesla later fixed that line to v14.3.10 includes. Automatic Collision Evasion is still on this HW4 build.

FSD (Supervised) 14.2 Lite for HW3 Model 3/Y, distilled from HW4 V14. Notes unchanged. Firmware 2026.27.10 (September 18, 2026) is the same Lite path, not ACE. Tracker card date stays September 8, 2026 (original 2026.27.6). HW4 on that package is 14.3.10.

FSD 14.3.9 on firmware 2026.27.6 adds Automatic Collision Evasion. It can activate Full Self-Driving (Supervised) while you are driving manually if you are not sufficiently attentive, or if Supervised may have been unintentionally disengaged.

Tesla’s invite-only Cybercab event is 4:45 p.m. Thursday, downtown Austin, Tesla Cybercab engineering lead Eric said. Texas listed purpose-built Cybercabs on the automated-vehicle registry. A listing is not a paid fare.

Official 14.3.8 notes match 14.3.7. The useful change is firmware 2026.26.6.5 — FSD on the 2026 Summer Update.

NTA’s Aug 20 order allows up to 5,000 vehicles in Clark County and replaces the 10-car Strip interim. Tesla has 120 days to comply before paid service. Not a launch.

Official Austin event entries run Aug 17–23 (five winners Aug 25). Nevada signed a 10-car Strip-corridor permit, not a launch.

For a driver who will use FSD (Supervised), a month-to-month subscription can be worth a trial. HW3 and HW4 are not running the same software.

Official 14.3.7 notes match 14.3.6. The useful change is the Aug 1–9 rollout, plus 14.1 Lite for HW3 on firmware 2026.21.6.

As of August 2026, HW4 runs FSD (Supervised) 14.3.7 while HW3 Model 3/Y runs 14.1 Lite on the same firmware family. Same supervised product name—different software branches.

Firmware 2026.21.6 (August 9, 2026) brings FSD (Supervised) 14.1 Lite to HW3 Model 3/Y—distilled from HW4 v14, not the same as HW4’s 14.3.7 on the same package.

From April through June 2026, FSD (Supervised) 14.3.2–14.3.4 layered a unified ASS/FSD/Robotaxi model, intervention feedback, summon speed, streaks, and Cybertruck summon—without rewriting the 14.3 stack.

FSD (Supervised) 14.3 on firmware 2026.2.9.6 (April 7, 2026) brought Tesla’s RL training upgrade, vision-encoder refresh, and MLIR compiler rewrite to HW4. Here is what the official notes actually say.

One wrap for FSD (Supervised) 14.2.2.x in January–February 2026: arrival options, emergency vehicles, vision routing, and polish—before 14.3 became the real step-change.

Tesla has sent out an email reminding owners that FSD (Supervised) is currently transferable to new vehicle purchases until March 31, 2026 for vehicles that have the FSD package purchased outright.

Today, Tesla has removed the Autopilot option from new vehicle purchases in the US and Canada, as reported by Sawyer Merritt.
