Performance - Models - Sound - Bass - Din
“Performance models need to have a more assertive sound, with more bass. It cannot be a high pitched din, like a sewing machine. It has to be futuristic,” he said, adding that SUVs will have a deeper sound to reflect their bigger size.

For its new EQC model, German rival Mercedes-Benz developed an artificial humming noise loud enough to warn pedestrians that the vehicle is approaching, but not disturb its passengers.
“We want the car to be as quiet as possible from the interior, but there are rules for sound decibel levels for the...
