The electric drivetrain may be the answer you're looking for. The electric motor is much simpler than the ICE.
There is a version of a hybrid that uses an ICE to charge the batteries, that would allow you to have an entirely electric drivetrain, but still retain the flexibility of a hybrid vehicle.
I don't think the auto companies are in favor of a less complicated vehicle. The simpler the autos become, and the fewer parts are used, the less profit there is in parts.
