Tesla's software train is finally picking up its Full Self-Driving passengers. On September 1, 2026, the company began rolling out 2026.27.200, the first update that fuses the 2026 Summer Update feature package with FSD (Supervised) 14.2.2.6 for Hardware 4 vehicles in Europe — closing a split that had left FSD owners waiting weeks for mainstream features everyone else already had.
Not a Tesla App's release-notes tracker describes the build simply as “FSD with the Summer Update in Europe.” Rollout data from TeslaFi showed 83 cars, roughly 0.7 percent of the fleet, on the new version within a day of release — a sign the push was just getting underway.
Why FSD Cars Fell Behind
For much of 2026, Tesla shipped its software on two tracks. Vehicles with FSD rode a separate “FSD branch” — many sat on the 2026.21.x line — while the rest of the fleet received the 2026.26 Summer Update starting in July: Grok voice commands, Caraoke with scoring, automatic navigation, refined range estimates, custom wraps, and welcome animations.
The gap was structural. Because FSD builds are merged into the main branch later, after extra testing, owners on the FSD track tended to get cabin and entertainment features a month or more after everyone else. Autoevolution noted the Summer Update reached North American cars about a month before FSD-equipped ones. Updates like 2026.27.200 exist to close exactly that delay.
What Lands on FSD Vehicles Now
2026.27.200 is not a new feature dump so much as the Summer Update finally arriving on the FSD branch. For cars previously parked on the FSD track, the release notes now list the full package: Grok Commands and the “Hey Grok” wake word, Preferred Routes and Automatic Navigation, Caraoke with scoring, custom wrap uploads from the phone app, Set Arrival Energy, camera preview at any time, speed-camera symbols on route, welcome animations, and a rear-display lock.
Not every feature reaches every car. “Hey Grok,” Grok Commands, and Caraoke scoring require the AMD Ryzen infotainment processor, and welcome animations are limited to the new Model 3 and Model Y. The rollout itself is gradual, delivered over Wi-Fi.
“This update includes FSD with the Summer Update in Europe.”

America vs. Europe: Same Update, Unequal FSD
The Atlantic merge happened on both sides, but not with equal FSD content — European builds must be approved by regulators (the Dutch RDW certified the 14.2.2 line in April) before reaching customers, so Europe ships an older FSD while the U.S. moves faster. Hardware 3 vehicles on both continents stay on the separate FSD v14 Lite branch.
| Market | Build | Rollout began | Bundled FSD | Vehicles |
|---|---|---|---|---|
| United States / Canada | 2026.26.6.5 | Aug 26–27, 2026 | FSD v14.3.8 | HW4 S/3/X/Y, Cybertruck |
| Europe | 2026.27.200 | Sep 1, 2026 | FSD 14.2.2.6 | HW4 Model S/3/X/Y |
| HW3 (both) | FSD v14 Lite line | ongoing | FSD v14 Lite | HW3 Model 3/Y |
When the U.S. rollout began in late August, investor and FSD user Sawyer Merritt flagged what the merge meant for owners: “Tesla FSD V14.3.8 is now officially starting to roll out, and it comes with the 2026 Summer Update!” Europe is now following the same playbook, just on its regulator-approved FSD version.
An OTA Recall Remedy, Bundled In
Alongside the feature merge, 2026.27.200 quietly carries a remedy for EU Recall Submission 2026_103555 on Model 3 and Model Y. Tesla's release notes say the software “restores compliance with UNECE Regulation No. 135” — delivered over the air, with no service visit required.
The Bottom Line for FSD Owners
The two-track era is ending. FSD vehicles in Europe now get the same Summer Update features as the rest of the fleet, and future seasonal updates should land on FSD cars at the same time instead of a month late. If your car has been stuck on the FSD branch waiting for Grok, Caraoke scoring, or smarter navigation, watch for the 2026.27.x prompt on your screen — the gap is closing.
