Electric cars were supposed to be less noisy than internal combustion engines. In fact, they are so quiet that manufacturers have to add “pedestrian warning sounds” to make sure pedestrians can hear cars and make way for them. However I can hear them when sitting in my apartment with the windows open. Or when I’m just walking around in the city. In the end, I find some of them more noisy and annoying than internal combustion engines when they are moving at low speed.
So far the most noisy electric cars to me are Hyundai and Chevrolet.
I know they are just complying with safety regulations in their own way. After all, people can’t drive a two ton lethal silent vehicle at speed in compact and dense urban environments without at least making some sort of alien spaceship noise, for safety. But it’s making some electric cars annoying to me. So in the not so distant future, living in a city will sound like this?!
So, aside from those two, what are the other brands that are making their electric cars more noisy and annoying than cars with internal combustion engines?
That is wrong. EV tires are different to reduce noise, EVs have lower air drag, also to reduce noise. The phenomenon engineers have addressed is called tire roar, it is minimal in EVs because of tread design and an inner foam liner.
So I looked into it a tiny bit, and I am not surprised. These tires can reduce noise a bit indeed: mainly FOR THE PEOPLE INSIDE THE CAR because those notice it more now where they used to not notice it much because of their own engine being louder in the cabin.
Even if newer tires end up making it relatively more silent than older tires, the heavier vehicles (ever larger SUV’s + very heavy battery) will probably mean it’s a zero sum game compared to the old cars and tires. There is no magic tire eliminating the rubber-road surface noise. Cars on roads are noisy, the only thing effectively keeping the noise down is speed reduction in cities or building expensive tunnels.
Sources?
Why would air drag be lower? Big SUV cube = big SUV cube. The only difference is lack of air intake grill in front.
There are roads “near” me (750m - 1500 m) away with speed limits 80-120 km/h. That’s already pretty damn far away compared to many other buildings in average cities, and there’s lots of stuff in between me and the roads, like other buildings, parks, sound shield barriers next to the road, et cetera. Yet, when the wind is coming from that direction, it is very very loud, especially at night. Even at such far distance and it not being just open plains between the roads and me… I find it quite hard to believe there would suddenly be new fancy tires that reduces this noise, and mainly: why wouldn’t the same tires be used on internal combustion cars then? There’s also the “whisper” asphalt. Yeah, it means a dB or two less, but it sure as hell ain’t fixing the problem completely for me.
I live right on the corner of a 50km/h collector street and the noise is terribly distracting. Not counting any of the souped up racing bikes or modded straight piped track cars that zip past, from my back yard you can hear the road noise from the traffic coming well before it actually arrives.
