Add FSD to a Kia K8 Hybrid? Here's what works

Tesla's FSD stays on Teslas. But your K8 Hybrid can steer itself and follow traffic with one device plugged in behind the mirror.

Yes. Your K8 Hybrid is on comma's list.

comma lists the 2023 K8 Hybrid. It needs Highway Driving Assist II on the car. The car's own adaptive cruise keeps speed control; an early openpilot option exists. Steering works all the way down to a stop.

Steers itself in the lane

Continuous centring on highways and most roads, not a nudge back from the line.

Follows the car ahead

Your car's adaptive cruise keeps doing the gas and brakes while openpilot steers.

You stay in charge

A driver camera checks your eyes. No city turns, no naps, no FSD claims.

How to add it to your K8 Hybrid

Four steps. No wiring cut, no dealer visit.

  1. 1

    Confirm your year and trim

    Open your exact K8 Hybrid below. Trim names decide whether the car has the cruise and camera openpilot needs.

  2. 2

    Order the comma four with the Hyundai Q connector

    Pick your car in comma's shop and the right harness is added. Nothing else is required.

  3. 3

    Mount it behind the mirror

    Stick the mount high and centred, plug the harness in at the camera, and route one cable. About fifteen minutes.

  4. 4

    Drive a few minutes, then engage

    It calibrates on your first drive. Then press your cruise button and the K8 Hybrid takes the lane.

Highway Driving Assist versus openpilot

Kia says HDA only works on certain federal highways. openpilot centres the lane on most roads for the EV6, Telluride, Niro, and more.

Questions K8 Hybrid owners ask

Is this Tesla FSD for a K8 Hybrid?

No. FSD is Tesla software for Tesla cars. This is openpilot, an open-source driver-assist system that steers and follows traffic on your K8 Hybrid. You watch the road and stay responsible.

Which Kia K8 Hybrid years work?

comma lists the 2023 K8 Hybrid, with Highway Driving Assist II. Open the exact year below to confirm your trim.

Do I keep Highway Driving Assist?

Yes. The harness sits between the car and its camera, and your factory safety features keep working. Unplug it and the car is stock again.

Does it handle stop-and-go traffic?

Yes on the listed K8 Hybrid years. It slows to a stop behind traffic and moves off again on its own.

Is there a subscription?

No. The device and the software are a one-time purchase. comma prime is an optional extra for remote access and longer drive storage.

Do I need to keep my hands on the wheel?

Not constantly. A small camera watches that your eyes stay on the road, and openpilot warns you and stops steering if they do not.
