Why are electric cars silent?
In fact they have laws stating that “quiet” EVs must automatically generate artificial cautionary sounds like beeps and chimes, at speeds lower than 30 kmph. Apparently at speeds higher than this, the road and tyre noise and the sound of wind resistance, are loud enough to alert pedestrians or other road users.
Are electric cars selling well?
Sales of electric vehicles, including plug-in hybrids, are projected to be less than 4% of U.S. sales this year, according to industry forecasters. Of those, all-electric models — such as Teslas — are only at 2.6% of the market, or about 394,000 vehicles, according to LMC.
Do Teslas make a noise?
Electric vehicles are soundless. Even though the Tesla cars are super expensive than internal combustion engine-powered cars, they can’t make a noise like the ICE engines.

Because an electric car doesn’t need a clutch, it also doesn’t require gears. Electric vehicles don’t feature a multi-speed gearbox like conventional petrol or diesel vehicles. Instead, they have just one gear. … In contrast, electric motors generate 100 per cent of their torque at very low speeds (under 1,000 rpm).
