content: Not entirely sure what you mean here. Electric vehicles have substantially lower maintenance costs with next to no regular maintenance even necessary. The exact figure in cost is mostly cited as about a 33% savings. No moving parts except the motor is a big one. Kind of like in your computer how one of the first things to go is usually a hard disk. Moving parts stress systems, and combustion engines are full of numerous extremely high energy moving parts. Instant torque means electric engines don't even have transmission/gears.
