This is what the person that I was responding to wrote, and it's objectively wrong: >Hybrids are the worst of both worlds when it comes to maintenance. They have their benefits and are key to fighting climate change, but mechanically you inherit all the problems from both sides. Also, much more complex is a value judgement. Complex in what way? High voltage electronics isn't exactly "not complex", and the coolant loops in BEVs are more complex than those in regular cars, because the tolerances are tighter. I'm going to go out on a limb and assume that you mean mechanical complexity, but even then, that's not a given for ICEs. Gas turbines can have as little as one moving part, and there are piston engines that can get away with as few as four (the piston-conrod-crankshaft assembly and a compressor wheel). At the end of the day, a good design has the minimum amount of complexity necessary to perform a given task, and no more. Given that BEVs are fundamentally unable to replace ICEVs in several niches (e.g. those relying on on-street parking, off-roading), maybe a little more complexity is warranted? As is, they aren't a 1:1 replacement for a standard car, and that's okay, but they're being marketed as such which is a recipe for failure.

I don’t think that a single-moving-piece gas turbine powered cars are currently on the market? And how many are single piston? Go carts and motorcycles maybe, but cars? And I was using complex as a shorthand for „more things to maintain“.

  A few companies have tried small APU range extenders, but there wasn't really a market for it at the time. The point was more that complexity is relative and not necessarily a given, and it's not necessarily a bad thing if it's required. A door is simpler than a bed, but I'd still rather sleep on a bed. Maintenance is a function of usage. BEVs still have coolant and lubricants, which means they also have pumps. They have a HVAC system which also means filters and refrigerant. Yes, you don't have to replace spark plugs and a timing belt, but both of those are infrequent and generally easy. You might have to replace brake pads less, but hybrids share that same feature. Hell, hybrids don't even have fan belts, alternators, ignition motors, and transmissions these days. They share nearly all of their underlying foundation with BEVs, for most of the same reasons you would want to go BEV in the first place.
