You may have misread the parent comment, which talked about HYBRID vehicles being more reliable than ICE-only vehicles. Hybrid vehicles include all of the comments of an ICE vehicle, plus they have electric batteries and motors, and may have a system of transferring power from either system to the wheels. Overall they have higher complexity than either ICE or electric-only vehicles.

They have higher complexity, but also more redundancy. Likely neither of the powertrains experiences the same rate of wear and tear as either would experience on ther own.

Apologies I did misread that.

This is not true, at least for the most popular Toyota hybrid drive train. It's probably got fewer moving parts than the ICE counterpart by virtue of dispensing with the automatic transmission.

  Check this diagram and tell me it's simpler than an engine and transmission. https://automotorpad.com/toyota/83449-funcionamiento-sistema-hibrido-toyota-prius.html https://automotorpad.com/toyota/83449-funcionamiento-sistema... It's essentially an engine, a transmission, another transmission (power split device), a drive motor and a generator.

    Most of the images there are broken, all I see are some conceptual block diagram type things. Find a teardown of the hybrid unit and compare to a teardown of any automatic, look at the actual internal complexity and moving parts. I was surprised. Here's a video of the P710: https://m.youtube.com/watch?v=O61WihMRdjM https://m.youtube.com/watch?v=O61WihMRdjM
