2026.27.11 Release Notes

This release includes FSD v14.3.10 and FSD v14.2 Lite. It follows update 2026.27.10 as an FSD refresh, with the FSD versions unchanged.

Vehicle-to-Home with Powerwall

Availability: CT.

Your Tesla can extend your homes backup power during an outage by sharing its battery with your Powerwall. When connected and enabled, the vehicle will automatically support your homes energy needs as required.

Enable it via Charging > Powershare. The vehicle must be parked and plugged into a compatible Wall Connector, with charge above your configured discharge limit. Requires a Powerwall.

Automatic Collision Evasion

Supported hardware: HW4. Supported models: New S, 3, New X, Y, CT.

Automatic Collision Evasion can activate Full Self-Driving (Supervised) to attempt to keep the vehicle safe and then continue driving. It may engage while you are driving manually if the system detects you are not sufficiently attentive to the road (for example, reaching toward the back seat), or if Full Self-Driving (Supervised) was unintentionally disengaged.

See your Owner's Manual for more details.

FSD (Supervised) v14.3.10

Supported hardware: HW4. Supported models: New S, 3, New X, Y, CT.

Full Self-Driving (Supervised) v14.3.10 includes:

Upgrades to the Reinforcement Learning (RL) stage of training the FSD neural network, improving performance across a wide range of driving scenarios.
Upgrades to the neural network vision encoder, enhancing understanding in rare and low-visibility situations, strengthening 3D geometry comprehension, and broadening traffic sign understanding.
A ground-up rewrite of the AI compiler and runtime with MLIR, delivering 20% faster reaction time and speeding up model iteration.
Mitigations for unnecessary lane biasing and minor tailgating behaviors.
More decisive parking spot selection and maneuvering.
Improved parking location pin prediction, now shown on a map with a P icon.
Enhanced responses to emergency vehicles, school buses, right-of-way violators, and other uncommon vehicles.
Better handling of small animals through focused RL training on difficult cases and added rewards for proactive safety.
Improved traffic light handling at complex intersections with compound lights, curved roads, and yellow light stops, driven by RL training on challenging examples sourced from the fleet.
Improved handling of rare or unusual objects that extend, hang, or lean into the vehicle path by leveraging infrequent events sourced from the fleet.
Better management of temporary system degradations by maintaining control and automatically recovering without driver intervention, reducing unnecessary disengagements.
Improved driver monitoring sensitivity with better eye gaze tracking, eyewear handling, and higher accuracy in variable lighting.
Unified the model between Actually Smart Summon, FSD, and Robotaxi for more capable and reliable behavior. (New in FSD v14.3.2 for non-Cybertrucks, New in FSD v14.3.4 for the Cybertruck)
Actually Smart Summon max speed is now increased to 8mph (13km/h). (Added in FSD v14.3.3, not available on Cybertruck)
Option to help Tesla improve Self-Driving by selecting an intervention reason on the main screen after taking over. (New in FSD v14.3.2)
Display of distance traveled in FSD (Supervised) without an intervention, and the Self-Driving App shows your longest intervention-free streak. (Added in FSD v14.3.3)
Parking options now appear on the map upon arrival. (Added in FSD v14.3.4)

Upcoming improvements:

Expand reasoning to all behaviors beyond destination handling.
Add pothole avoidance.

Full Self-Driving (Supervised)

Supported hardware: HW4. Supported models: New S, 3, New X, Y, CT.

With your supervision, Full Self-Driving (Supervised) can drive your Tesla in most situations: it can start from a parked position, change lanes, choose forks to follow your navigation route, navigate around vehicles and objects, make left and right turns, and park at your destination. You and anyone you authorize must stay attentive and exercise additional caution. It does not make the vehicle autonomous. Do not become complacent.

Full Self-Driving (Supervised) is enabled on your vehicle. To use it, press the Start Self-Driving button on the UI or press the right scroll wheel once. You can disable Full Self-Driving (Supervised) in Autopilot Settings.

FSD (Supervised) v14.2 Lite

Supported hardware: HW3. Supported models: 3, Y.

FSD (Supervised) v14.2 Lite includes:

Distillation of intelligence from HW4 V14 to HW3, enabling HW3 to learn scenario handling guided by HW4 V14. This brings HW4 improvementsincluding Reinforcement Learning (RL) and offline modelsto HW3.
Improved proactive and reactive responsiveness across navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-ins.
Greater comfort in nominal scenarios with fewer false slowdowns, smoother steering, and more consistent lane centering.
Introduction of parking, unparking, and reversing capabilities.
Arrival Options to choose where FSD should pull over or park: Parking Lot, Street, or Driveway.
Speed Profiles available at all times for further customization of driving style.

Start Self-Driving from Park

Supported hardware: HW3. Supported models: 3, Y.

A button appears on the screen when driver requirements are satisfied. Examples of requirements include:

Driver is seated in the drivers seat
Driver is buckled
Cabin Camera is unobstructed

Brake Confirm requires pressing and releasing the brake pedal before FSD (Supervised) can be activated. When Brake Confirm is disabled, pressing the button allows Self-Driving to apply the brakes and engage FSD (Supervised). If driver detection requirements are not met or FSD (Supervised) does not detect a driver, you will need to press and release the brake pedal to confirm. You can enable this in Self-Driving > Brake Confirm.

This feature does not make the vehicle autonomous; remain attentive and ready to take over at any time. Only a licensed driver authorized to operate the vehicle should have access to the drivers seat position any time the vehicle is not in Theater or Arcade modes.

Arrival Options

Supported hardware: HW3. Supported models: 3, Y.

Select an arrival option such as Parking Lot, Street, Driveway, or Pull Over for Robotaxi-style drop-offs.
Preferences for arrival options and preferred parking positions are saved per destination.

Speed Profiles

Supported hardware: HW3. Supported models: 3, Y.

FSD (Supervised) now determines an appropriate speed using a combination of driver profile, speed limit, and surrounding traffic.

New Speed Profile SLOTH offers lower speeds and more conservative lane selection than CHILL.
Driver profile has a stronger effect on behavior; more assertive profiles allow a higher max speed.
The right scroll wheel up/down now adjusts the Speed Profile setting instead of your precise max speed offset in mph/kph.
