I'm only moderately familiar with this topic (mostly from following racing, where many major series have integrated hybrid powertrains), but this doesn't seem accurate to me. All the hybrid vehicles have to develop and integrate an ICE in addition to the hybrid system, not instead. I don't see where the simplicity gains you refer to would come from.

Again, I'm not very knowledgeable here, I just have intuition to go on and familiarity with the fact hybrids are definitely viewed as more complex to develop and race, in motorsports. I'd love to be more informed if I'm missing some major factors
