> How are ICEs quieter than EVs? Are you talking about the artificial noise EVs put out at low speeds so they don't sneak up on people? I think your second sentence answers your first. Car noise = tire noise + motor noise. EVs have very low motor noise compared to IC. EVs also tend to have better cabin dampening on average, but that likely has to do with price-band consumer expectations, and not inherent to the method of propulsion. | ||

You know you can disable that. It might be against the law though, and it isn't the EVs that demand noise, it is the society that demands them not to be silent killers. Even Hybrids have to make this noise when they are running on their electric drive trains. But let's say ICEs were made as quiet, they would be demanded to make noise as well. Also, no one has done anything about tire noise yet, so at high speeds, EVs and ICEs are about the same. | ||

EVs are also much heavier, which contributes to lower noise as well. You've got a massively heavy battery pack between you and the road. |
