> an EV is still a car. So you still have the same old things ... No, an ICE has a very complex drivetrain with thousands of moving parts. Belts, transmissions, gears, fuel filter, oil seals and gaskets, batteries (ICE's need them too), spark plugs, fuel pump, fuel injector, alternator, radiator and water pump, catalytic converter, etc etc . Brakes also wear slower on EVs since regnerative braking captures some energy. Electric motors themselves are far more reliable and simpler than ICE motors.

since you mention the radiator, the EV needs quite the cooling as well; although I do agree for the most part. The electric motors are a lot simpler than even a small engine lawnmower.

  > batteries (ICE's need them too) I've replaced a few ICE batteries in my time. You can replace them at home in 5 minutes and they are a gazillion times cheaper than an EV battery. :) > ICE has a very complex drivetrain with thousands of moving parts. Belts, transmissions, gears, fuel filter, oil seals and gaskets This whole thing about ICE is FUD IMHO. Yes, complex, but on modern ICE vehicles is highly-reliable. Also I would argue with EVs you are replacing ICE "complexity" with other complexity. For example, in EVs you now have individual motors on four wheels (i.e. potentially four points of failure), you have all the software in EVs etc. etc. etc. I would also argue that the ICE "complexity" of what you speak is NOT where the bulk of ICE maintenance costs come from. Afterall, topping up the oil and replacing gaskets is kids work. The bulk of ICE maintenance will ultimately be the same as EV maintenance, i.e. all the wear-and-tear parts I listed already, such as tyres.

    Most EVs don't have four motors on each wheel. They'll have one or two.

    It also depends a lot on what type of ICE we are talking about. A very high power output downsizing engine with two turbochargers, direct fuel injection, EGR, intercooler, electric oil pump(s) (for turbo cooling), variable valve timings and/or lift systems etc. -- what you'll typically find in a high trim ICE mid-class car -- has far, far more parts and experiences a lot higher stresses than e.g. the naturally aspirated port injection engine you might find in a city car.

Those "complex parts" (engine and gearboxes) usually only require yearly oil changes and replacement of minor parts as you mentioned (spark plugs, plug wires, belts, tensioners--maybe injectors every 100kmi) for the first quarter million miles. At 10kmi/yr that's 25yr. The complexity as defined by parts count doesn't have much practical impact on TCO.

That said, my BEV is currently in service due to the charger shorting out for some reason. Not sure which came first, but the battery cable harness also got damaged and had to be replaced. A quick change once the parts arrived they said. The car is still under warranty so won't cost me a dime, but if the bill they presented me with is real and not some "medical bill" shenanigans, the charger alone would be 1/8th the price of the car as new, total repair cost 1/5th... So yeah, still some expensive parts that can break. Was quite happy with very little maintenance costs so far, but if that price was real and charger breaks after warranty is out, the whole value proposition is quite different.
