I'm concerned like this a quite a blanket statement. Are all EVs that much simpler? There are simple EV drivetrains and there are complex EV drivetrains. Not all EV drivetrains are the same.

This also applies to ICE. Most ICE drivetrains that do not have forced induction tend to be quite simple. Forced induction makes the drivetrain much more complex and puts a lot more strain on the drivetrain, and is one of the reasons why Toyota has stayed away from forced induction.

Is the drive train in a Tesla Model X P100d much simpler than that in a 1.5 NA Yaris? I'm not sure, and would love to be proved incorrect on this.

> Are all EVs that much simpler?

Yes.

Internal Combustion Engines have at a minimum a Combustion System, Ignition System, Fuel Delivery System, Exhaust System, and a Cooling System. These can vary in complexity but, apart from air cooling, any one of those systems will be more complex than an EV's electric power-train. On top of that, most of the parts of an ICE are mechanical moving parts where as most of the parts of an electric motor are stationary non-moving parts.

ICE vehicles almost universally have a transmission gear box that contains a configurable gear system to alter the gear ratio of the vehicle. All EVs on the market use a fixed gear box with a single reduction gear set.

Yes, dramatically.

Where are the complex EV drivetrains? It isn't remotely the same thing as ICE. Even the most reliable ICE drivetrains are extremely complex. Toyota just uses conservative and overbuilt ICE technology to achieve remarkable reliability. That's fine, but still has tons of moving parts compared to electric drivetrains.
