The hybrid transaxle on the Prius is a technological marvel. While the transaxle and battery pack add their own significant costs, complexity, and failure modes, they also eliminate a lot of the components on a conventional gas engine vehicle. In my area, it is common to see a lot of hybrids used as taxis. Some of the older ones I see likely have 500k miles.
