I think Kona Ultimate gets ACC/LFA/LKA, while Kona Limited gets FCW/LKA only.
Ioniq Limited gets all of them: ACC/LFA/LKA/HDA, where HDA, AKA Carrie Underwood, really takes it up a notch from “driver assist” to “you are merely a passenger in the driver seat”.
It wouldn’t surprise me if I messed them up in this post. Someone can please correct me.
Tl~dr: Fully loaded Ioniq and Palisade have full blown “Jesus Take the Wheel” - other KIA/Hyundai models have less aggressive versions of the technology: more focused around safety than autonomy.
