The latest Prius is an amazing success. It doesn't have a gearbox,
just
one plaetary gear assembly.

Whereas a gearbox is what?

Shifting ratios between cogs. The Prius doesn't do this or have a CVT which
has pullies and a belt. Just a simple assemmbly.

It has no mechanical transmission. No mechanism to shift gears or wind
pullies in and out. It is very simple. You need to look more and understand
how a planetary system works. There is no ratio selection. It is simpler
than a normal car. No complex power sapping transmission, juts a planetary
gear assembly, which
just turns, as do bearings. The "complexity" is people not understanding
it.
