When you remove the noise of the combustion engine, the noise inside the cabin is reduced significantly. But as a result, you start to notice other noises, like wind noises, and much more. In many cases, they may be even more bothersome than a car with a combustion engine. Wind noise comes from aerodynamics, or the friction between the airflow around the car and the car’s chassis itself. Therefore, the shape of the car is crucial to what you hear in the cabin.
