eli5: What makes electrical motors in cars so quiet?

302 views

I mean in comparison with other motors, like power tools or even home appliances? Is it just sound insulation or is it a different kind of motor?

Carmakers can make quite quiet gas motors, but market research shows people expect noise, so they add extra noise.

It turns out people don’t believe something is powerful unless it’s loud.
This is probably also true for power tools.

I wish they gave consumers a silent option.
