I thought the same thing and was disappointed to see a planetary gear setup to turn an outer ring gear. Shame, we have come so far in EV motor design and yet Hyundai seems stuck on drivetrain power design.

My experience with a planetary gear in a bicycle is that it produces additional noise. I wonder if this would be noticeable for an automobile.

I'm sure it would. Any mechanical gears will produce noise at higher velocities so curious what this sounds like myself. Electric hub motors produce a wine from the EMF that is audible but that's a different sound (the hum of a tesla going by) or a Surron that uses a radial flux motor with chain link gears (this is my favorite hobby design, chain gears are super useful).

the sound is not coming from EMF, but rather from speakers due to safety regulations for pedestrians
